The triangles are similar. The area of the larger triangle is 200 cm².
What is the area of the smaller triangle?
12.5 cm²
50 cm²
100 cm²
200 cm²
Answer:
The correct answer option is 12.5 cm[tex]^2[/tex].
Step-by-step explanation:
We are given two triangles that are similar with one of the corresponding sides with known values.
The ratio of the corresponding sides of the smaller triangle to the larger triangle is [tex]\frac{16}{64} =\frac{1}{4}[/tex]. So the ratio between the areas of these triangles will be [tex]\frac{1}{4^2} =\frac{1}{16}[/tex].
If the area of the larger triangle is 200 cm[tex]^{2}[/tex] then the area of the smaller triangle will be = [tex]\frac{1}{16} *200=12.5[/tex].
Therefore, the area of the smaller triangle is 12.25 cm[tex]^2[/tex].
Formula to find Area of a triangle is
A=(height×base)/2
base of bigger triangle is=64cm^2
base of smaller triangle is=16cm^2
Area of bigger triangle is =200cmCm^2
area of smaller triangle=?
we imagine
height = base
then area of bigger trianglewillbe=64*64/2=2048
and area of smallertriangle will be=16*16/2==128
but we are given thatarea of bigger triangle is 200
when we divide 2048/10
it approximately gives 200
similarly when we divide 128/10
it approximately gives 12.5cm^2
hence area of smaller triangle is 12.5cm^2

use the given information to prove that FG=HF
1. EG = HJ (Given)
2. EG = EF + FG, HJ = HF + FJ (Seg. Add. Prop.)
3. EF + FG = HF + FJ (Subst. Prop.)
4. EF = FJ (Given)
5. FG = HF (Subtraction Prop.)
It's challenging to demonstrate that FG equals HF as these may represent different elements or variables in different mathematics or physics contexts. At its simplest, FG seems to represent the gravitational force between two masses, and HF would need to represent the same force to hold true.
The equation given seems to pertain to gravitational forces where FG represents the gravitational force between two masses, electron and proton.
Given that FG = GMM where G is the gravitational constant (6.67×10-¹1 N·m²/kg²), m and M represent the masses of the electron and proton, to prove that FG=HF, it implies that HF represents the same gravitational pull.
However, without more detailed context or information, I can't further demonstrate or prove that FG does equal HF as these terms may refer to different elements or variables in different contexts of mathematics or physics problems.

1.does y vary directly with x? If it does, write an equation for the direct variation.
x|y
−3|2.25
1 |−0.75
4 |−3
Answer:
y = -.75 x
Step-by-step explanation:
To determine if y varies directly with x, we look at y/x and see if it is a constant
y/x = 2.25/-3 = -.75
= -.75/1 = -.75
=-3/4 = -.75
Since it is a constant, it has direct variation. The constant of variation is -.75
y = -.75 x
An ice cream vendor sells three flavors: chocolate, strawberry, and vanilla. Forty five percent of the sales are chocolate, while 30% are strawberry, with the rest vanilla flavored. Sales are by the cone or the cup. The percentages of cones sales for chocolate, strawberry, and vanilla, are 75%, 60%, and 40%, respectively. For a randomly selected sale, define the following events:
a. chocolate chosen
b. strawberry chosen
c. vanilla chosen
d. ice cream on a cone
e. ice cream in a cup
Find the probability that the ice cream was sold on a cone and was strawberry flavor
Answer:
Step-by-step explanation:
Sales of the chocolate ice cream is 45%, 30% for strawberry and 25% (100%-45%-30%) of vanilla.
Percentages of cone sales for chocolate, strawberry and vanilla are 75%, 60% and 40%respectively.
A. Probability chocolate chosen: 45%=0.45
B. Probability strawberry chosen: 30%=0.30
C. Probability vanilla chosen:25%=0.25
D. Probability ice cream on a cone: 75%×45%+60%×30%+40%×25%
=0.75×0.45+0.60×0.30+0.40×0.25
=0.3375+0.18+0.1
=0.6175
E. Probability ice cream in a cup: 1- Probability ice cream in a cone
=1-0.6175
=0.3825
Probability that the ice cream sold on a cone and was strawberry flavoured is : 30%×60%
=0.30×0.60
=0.18
Answer: 0.18.
Step-by-step explanation: Let us define the following events
A= event that chocolate chosen,
B=event that strawberry chosen,
C=event that vanilla chosen,
D=event of choosing ice-cream on a cone
and
E=event of choosing ice-cream on a cup.
Then, according to the given information, we have
P(A)=0.45, P(B)=0.30, P(C)=0.25, P(A\D)=0.75, P(B\D)=0.60 and P(C\D)=0.40.
Therefore, the probability that the ice-cream was sold on a cone and was strawberry flavour is given by
[tex]P(B\cap D)=P(B)\times 0.60\\\Rightarrow P(B\cap D)=0.30\times 0.60\\\Rightarrow P(B\cap D)=0.18.[/tex]
Thus, the required probability is 0.18.

Tickets to a show cost different for seniors, children, and adults. Adult tickets are twice as much as senior tickets. Two senior tickets plus one children's ticket cost $17. Two children tickets plus one adult ticket cost $24. How much does one senior ticket cost? A) $5 B) $7 C) $9 D) $10
Answer:
The senior's ticket cost is A, $5.
Step-by-step explanation:
say a children's ticket was $7; 7 + 7 + 14
so if an adult ticket is twice as much, let's say it was $10 per adult ticket.
one adult ticket plus two children's tickets would be $24 with these numbers.
two seniors ($5) + one children's ticket ($7) would be $17
therefore, we can conclude that a senior's ticket would cost $5

Find a parametric representation for the surface. The part of the sphere x2 + y2 + z2 = 144 that lies between the planes z = â’6 and z = 6. (Enter your answer as a comma-separated list of equations. Let x, y, and z be in terms of θ and/or Ď•.) (where â’6 < z < 6)
The parametric equations that represent the sphere surface between the planes z=±6 are x = 12*sin(θ)*cos(φ), y = 12*sin(θ)*sin(φ), and z = 12*cos(θ), with θ and φ being between π/3 and 2π/3, and 0 and 2π respectively.
Explanation:This question involves a mathematical concept known as parametric representation of a surface, specializing in spheres and planes. In a 3D coordinate system, the equation of a sphere is given by x² + y² + z² = r² where r is the radius of the sphere, but we restrict the z variable to lie in a certain range, which is between -6 and 6 in this situation.
To represent the sphere in parametric form, we often use spherical coordinates. The relationships between Cartesian coordinates and spherical coordinates are as follows: x = r*sin(θ)*cos(φ), y = r*sin(θ)*sin(φ), z = r*cos(θ). Here r = √144 =12, is the radius of the sphere.
Given the restrictions z = ±6, we have cos(θ) = ±6/12 = ±1/2, or θ = π/3 and 2π/3. So, the spherical coordinates range within 0 <= φ <= 2π and π/3 <= θ <= 2π/3.
This gives the parameters of the restricted surface in terms of θ and φ those are as follows: x = 12*sin(θ)*cos(φ), y = 12*sin(θ)*sin(φ), and z = 12*cos(θ).

The parametric equations which represent the part of the sphere x² + y² + z² = 144 that lies between the planes z = -6 and z = 6 are: x = 12*sin(θ)*cos(Ď•), y = 12*sin(θ)*sin(Ď•), z = 12*cos(θ), with 60° ≤ θ ≤120° and 0° ≤ Ď• ≤ 360°.
Explanation:The question asks for a parametric representation of part of a sphere lying between two planes. The given sphere equation is x² + y² + z² = 144, and the two planes are defined by z = -6 and z = 6. This is a common problem in multivariable calculus, and we solve it using spherical coordinates. In spherical coordinates, x= r*sin(θ)*cos(Ď•), y= r*sin(θ)*sin(Ď•) and z= r*cos(θ) where r is the radius, θ is the inclination angle, and Ď• is the azimuthal angle. For the given sphere, r = √144 = 12.
The bounds for z adds constraints to our inclination angle θ. Given -6 ≤ z ≤ 6, we determine corresponding bounds on θ. For z = r*cos(θ), we have -6 ≤ 12cos(θ) ≤ 6, or -1/2 ≤ cos(θ) ≤ 1/2. This yields θ values between 60° and 120°. The parametric equations describing the part of the sphere between the planes z = -6 and z = 6 are:
x = 12*sin(θ)*cos(Ď•)
y = 12*sin(θ)*sin(Ď•)
z = 12*cos(θ)
where 60° ≤ θ ≤120° and 0° ≤ Ď• ≤ 360°.

Quentin has 6 5/8 feet of lumber but needs another 2 3/4feet to complete the project he's working on. How much total wood will the project have used when finished?
Answer:
Total wood required for the project will be 9 3/8 feet.
Step-by-step explanation:
As given in the question Quentin has lumber of length = 6 5/8
feet =53/8 feet.
Now Quentin needs more lumber = 2 3/4 feet =11/4 feet or 22/8 feet.
So we can get total wood required by adding these two figures
That is = 53/8 + 22/8
= (53 +22)/8
= 75/8
= 9 3/8 feet
Answer:
[tex]The\ total\ wood\ will\ the\ project\ have\ used\ be\ 9 \frac{3}{8}.[/tex]

If William has 5 different shirts and 7 different pairs of pants, how many different combinations could he wear?
The question is asking how many different outfit combinations William can form if he has 5 shirts and 7 pants. It's a simple multiplication of the two numbers (5*7) resulting in 35 different combinations. Therefore, William could wear a different outfit for 35 days without repeating.
Explanation:The subject of this question is combinatorics, a branch of mathematics concerned with counting, both as a means and an end. In this specific context, we are looking at the number of different combinations that William can wear with the clothes he has. Since each shirt can be worn with any pair of pants, this translates into a simple product calculation.
William has 5 different shirts and 7 different pairs of pants. So, the total number of combinations of outfits he can put together is calculated by multiplying these numbers together. Hence, 5 shirts * 7 pants = 35 combinations.
This means that if William chooses a different combination each day, he could go for 35 days without wearing the same outfit twice.

How much money should be deposited today in an account that earns 3 % compounded semiannually so that it will accumulate to $8000 in three? years
To calculate the amount that should be deposited today in an account that earns 3% compounded semiannually to accumulate to $8000 in three years, we can use the compound interest formula.
Explanation:To calculate the amount that should be deposited today in an account that earns 3% compounded semiannually to accumulate to $8000 in three years, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the future value, P is the principal, r is the interest rate, n is the number of compounding periods per year, and t is the number of years. In this case, the future value (A) is $8000, the interest rate (r) is 3% or 0.03, the number of compounding periods per year (n) is 2 (semiannual compounding), and the number of years (t) is 3. Plugging these values into the formula, we get:
A = P(1 + r/n)^(nt)
$8000 = P(1 + 0.03/2)^(2*3)
$8000 = P(1 + 0.015)^(6)
$8000 = P(1.015)^(6)
To find the value of P, we divide both sides of the equation by (1.015)^6: P = $8000 / (1.015)^6. Using a calculator, we find that P ≈ $7383.42. Therefore, approximately $7383.42 should be deposited today in the account.

Answer:
A. 8 rows.
B. 3 toy soldiers.
Step-by-step explanation:
We are told that Meliza has 43 toys soldiers, she line them up 5 to fight imaginary zombies .
A. Let us find the greatest multiple of 5 from 43.
Multiples of 5 are: 5,10, 15, 20, 25, 30, 35, 40, 45,..
We can see the greatest multiple of 5 from 43 is 40.
Let us divide 40 by 5 to find the number of rows that Meliza can make.
[tex]\text{Number of rows with 5 soldiers in each row}=\frac{40}{5}=8[/tex]
Therefore, Meliza can make 8 rows of 5 from 43 toy soldiers.
B. To find the number of soldier in last row we will subtract 40 from 43.

The triangles below are similar.
Which similarity statements describe the relationship between the two triangles?
CHECK ALL THAT APPLY!!!!!!
Answer: choices B, C, D and E
B) triangle RSP is similar to triangle ZXY
C) triangle SRP is similar to triangle XZY
D) triangle PSR is similar to triangle YXZ
E) triangle RPS is similar to triangle ZYX
In short, the answers is nearly everything but the first and last answer choice
================================================
For the first triangle, angle S is 54 degrees. In the other triangle, angle X is also 54 degrees. This means that the two angles correspond as they are equal to one another. The answer will have the letters S and X show up in the same position, whether that position is the first, second or third place of the three letter sequence.
Choice A is not one of the answers. RPS ~ XYZ is false because of what I mentioned above. We see that S is shown last in RPS while X is shown first in XYZ. The letters S and X do not correspond together, so we can cross choice A off the list.
Choice B is one of the answers because we have R corresponding to Z (first letters of each sequence RSP and ZXY; both are 41 degrees) and we have S correspond to X, and we have P correspond to Y (both the same measure as well)
Choice C is another answer for similar reasons as choice B. The only difference is that R and S have swapped, so have X and Z. The order is important or else things wouldn't line up properly.
Choice D is another answer. Again we have the same correspondence of P to Y (both in the first slot), S to X (second slot), and R to Z (third slot). For each slot, the pair of angles are both the same measure.
Choice E is another answer. Similar reasons as before, just a different order.
Choice F is not one of the answers. We see that P and Z occupy the second slots, but they aren't congruent angles.

Point B is Point A reflected across the y-axis.
Step-by-step explanation:
Answer:
B is A reflected across the y-axis; only the signs of the x-coordinates of A and B are different.
Step-by-step explanation:

To find the equation of a line perpendicular to a given line, find the negative reciprocal of the slope and use the point-slope form of a line.
Explanation:To find the equation of a line that is perpendicular to the given line and passes through the given point, we first need to determine the slope of the given line. The given line has a slope of -1/5, which is the negative reciprocal of the slope we want for the perpendicular line. The negative reciprocal of -1/5 is 5/1 or 5. Now we have the slope of the perpendicular line and a point it passes through (-2, 7), we can use the point-slope form of a line to find the equation: y - y1 = m(x - x1), where m is the slope and (x1, y1) is the given point.
Substituting the values, we get: y - 7 = 5(x - (-2))
y - 7 = 5(x + 2)
y - 7 = 5x + 10
y = 5x + 10 + 7
y = 5x + 17
Therefore, the equation of the line that is perpendicular to the given line and passes through the given point (-2, 7) is y = 5x + 17. Option B is the correct answer.

The correct answer is B. y=5x+17.
To write the equation of a line that is perpendicular to the given line y-3=-1/5(x+2) and that passes through the point (-2, 7), first, we need to find the slope of the given line and then determine the slope of the perpendicular line, which will be the negative reciprocal of the given line's slope. The slope of the given line is -1/5, so the slope of the line perpendicular to it will be 5 (since the negative reciprocal of -1/5 is 5).
Next, we use the point-slope form of the equation of a line, which is y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point through which the line passes. Plugging in our slope of 5 and the point (-2, 7), the equation becomes:
y - 7 = 5(x - (-2))
Expand and simplify to solve for y:
y - 7 = 5x + 10
y = 5x + 17
The correct answer is B. y=5x+17.
