Step-by-step explanation:

to find the surface area we need to find the followng areas:  

And once we have those areas, we add them to find the surface area.

Area of the square:

the formula to find the area of a square is:

[tex]a_{square}=l^2[/tex]

where [tex]l[/tex] is the length of the side: [tex]l=5in[/tex]

thus the area of the square is:

[tex]a_{square}=(5in)^2\\a_{square}=25in^2[/tex]

Area of the triangles:

the are of 1 triangle is given by

[tex]a_{triangle}=\frac{b*h}{2}[/tex]

where [tex]b[/tex] is the base of the triangle: [tex]b=5in[/tex] (the base of the triangle is the side of the square)

and [tex]h[/tex] is the height of the triangle: [tex]h=6in[/tex]

thus, the area of 1 triangle is:

[tex]a_{triangle}=\frac{(5in)*(6in)}{2}\\ a_{triangle}=\frac{30in^2}{2}\\ a_{triangle}=15in^2[/tex]

the area of the 4 triangles is (we multiply by 4):

[tex]a_{4-triangles}=4(15in^2)\\a_{4-triangles}=60in^2[/tex]

finally we add the area of the square and the area of the 4 triangles to find the total surface area:

[tex]Surface=25in^2+60in^2\\Surface=85in^2[/tex]

Square root 114 represents the point p.

Given,

The point P value in the given figure is between 10 and 11.

We need to find which value in the option is represented by point P.

Given options are :

Sqrt 11 = 3.31

Sqrt 21 = 4.58

Sqrt 114 = 10.67

Sqrt 121 = 11

We need to see which option gives a value between 10 and 11.

We have,

Sqrt 114 = 10.67.

We also know that point P lies between 10 and 11.

Sqrt 114 gives a value between 10 and 11.

Thus Sqrt 114 represents the point p.

The probability of drawing three green marbles consecutively without replacement from a bag containing different colored marbles is approximately 0.018 when calculated step by step.

The question is about calculating the probability of drawing three green marbles in a row from a bag that contains multiple colored marbles. To find this probability, we need to use the concept of probability without replacement.

First, calculate the probability of drawing one green marble. There are 5 green marbles out of a total of 16 (7 red + 4 blue + 5 green), so the probability is 5/16. When we draw a green marble, we do not replace it, so there are now 4 green marbles left out of 15 total marbles. The probability for the second draw is then 4/15. Lastly, for the third draw, there are 3 green marbles out of 14, making the probability 3/14.

To find the overall probability of all three events occurring, calculate the product of the individual probabilities: (5/16) * (4/15) * (3/14). This gives us 60/3360, which simplifies to 1/56. To the nearest thousandth, that is approximately 0.018.

So the probability that all three marbles drawn will be green, to the nearest thousandth, is 0.018.

Answer:

Step-by-step explanation:

Multiplying bases with exponents means you have to multiply the base and add the exponent. So:

(10⁴)(5²) = 50⁶

(10³)(5³) = 50⁶

Now the equation is (50⁶/50⁶)³

Anything divided by itself will be one, so the number inside the parentheses is 1.

Now the equation is 1³, and 1x1x1 is 1.

Based on the graph, the domain of the function [tex]y=3\sqrt{x}[/tex] is [0, ∞].

In Mathematics and Euclidean Geometry, a domain is the set of all real numbers (x-values) for which a particular relation or function is defined.

The horizontal section of any graph is typically used for the representation of all domain values. Additionally, all domain values are both read and written by starting from smaller numerical values to larger numerical values, which means from the left of a graph to the right of the coordinate axis.

By critically observing the graph shown in the image attached below, we can logically deduce the following domain:

Domain = [0, ∞], {x|x ≥ 0}.

Answer: The length of radius of a circular pool is 7 meters

Step-by-step explanation:

Given that the circumference of a circular pool cover is about 88 meters

To find the length of radius

As we know circumference of a circle is given by

[tex]C=2\pi r[/tex] where C is circumference , and r is radius of the circle

Now as according to question we have

[tex]88= 2\pi r\\\\\Rightarrow 88= 2\times \dfrac{22}{7} r\\\\\Rightarrow r= \dfrac{88\times 7}{2\times 44} = 7 m[/tex]

Hence,the length of radius of a circular pool is 7 meters

Answer: 59%

Step-by-step explanation:

First, you should add all of the money together.

= $268 + $68 + $96

= $400

Now, put it into a fraction. Remember to have a percentage, you have to multiply the division by 100.

= [tex]\frac{268}{400}[/tex] x 100

= 59%

Answer:

6.38298% or 6.4%

hope this helps

To calculate the percentage decrease from 47 to 44, the difference is divided by the original number and then multiplied by 100. The result is approximately a 6.4% decrease.

To calculate the percentage decrease of the number from 47 to 44, we use the following formula for percentage decrease:

Percentage decrease = ((Original Value - New Value) / Original Value) × 100%

In this case, the original value is 47 and the new value is 44. So the calculation would be:

Percentage decrease = ((47 - 44) / 47) × 100%

Percentage decrease = (3 / 47) × 100%

Percentage decrease = 0.0638 × 100%

Percentage decrease = 6.38%

To give the answer to the nearest tenth of a percent, we round 6.38% to 6.4%. So, the number 47 is decreased by about 6.4% to become 44.

Mai, Tyler Kiran,Jada ratio = 4,2,1,1Tyler is double that of Jada

So expression could be f(t) 2 x 1t x 5 = 10

Step-by-step explanation:

The expression for the number of chips Tyler won, based on the number of chips Jada won, is 2j.

In this problem, we are asked to develop an expression for the number of chips Tyler won based on the amount Jada won. The relationships between the chips won are as follows: Kiran won as many chips as Jada (so if Jada won j chips, Kiran also won j chips), Mai won 4 times as many chips as Kiran (so Mai won 4j chips), and Tyler won half as many chips as Mai (so Tyler won 1/2 * 4j = 2j chips).

So, using j to represent the number of chips Jada won, the expression for the number of chips Tyler won would be 2j.

Answer:

±70

Step-by-step explanation:

Using a geometric sequence, it is found that the possible values of the 6th term of the sequence are -70 and 70.

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

The nth term can also be written as a function of the mth term, as follows:

[tex]a_m = a_1q^{n-m}[/tex]

In this problem, considering that we have the 5th and the 7th term, we have that:

[tex]a_7 = a_5q^2[/tex]

Since [tex]a_5 = 140, a_7 = 35[/tex]:

[tex]q^2 = \frac{a_5}{a_7}[/tex]

[tex]q^2 = \frac{35}{150}[/tex]

[tex]q^2 = \frac{1}{4}[/tex]

[tex]q = \pm \frac{1}{2}[/tex]

[tex]\pm \frac{1}{2}[/tex] of 140 is [tex]\pm 70[/tex], hence the possible values of the 6th term of the sequence are -70 and 70.

Answer:

f(-4)= -55

Step-by-step explanation:

We want to find f(x), or y, when x is equal to -4.

Therefore, we can substitute -4 in for x in the function.

f(x) = -2x^2 + 4x - 7

Substitute -4 in for x

f(-4) = -2(-4^2) + 4(-4) - 7

Evaluate the exponent

f(-4)=-2(16)+4(-4)-7

Multiply -2 and 16

f(-4)= -32+4(-4)-7

Multiply 4 and -4

f(-4)=-32-16-7

Subtract

f(-4)=-55

To find the height of the fourth bar in a relative frequency histogram, calculate the total frequency, subtract the sum of the first three frequencies, and divide the remaining frequency by the total frequency.

The relative frequency histogram given has four classes. The heights of the first three bars are 0.25, 0.35, and 0.1 respectively. To find the height of the fourth bar, we need to calculate the total frequency first. Then, subtract the sum of the first three frequencies from the total frequency. Finally, divide the remaining frequency by the total frequency to get the height of the fourth bar.

So, you need to draw square with sides of 1 dm. However, first, you need to transform from dm to cm.

We know that 1 decimenter (dm) equals 10 centimeters (cm).

That means the square sides are 10 centimerers long. So, you need to draw two squares like the first image attached shows.

Then, to draw their diagonals, you need to draw a line segment from one corner to its opposite corner, you should have an inclined line acroos each square. As the second image attached shows.

There you have it. Two squares of 1 dm side with on diagonal each.
