Check the picture below.
notice chord QR is a diameter, thus the vertex at P has a right-angle by Thales theorem.
-2x+15y=-24
2x+9y=24
solve the system of equation
Answer:
x = 12, y = 0
Step-by-step explanation:
Use elimination.
24y = 0
y = 0
Then plug back into the second equation.
2x + 9(0) = 24
2x = 24
x = 12
Plug back into the first equation to check.
Solve x/3 = x+2/2
x=?
Answer:
x = -6
Step-by-step explanation:
∵ [tex]\frac{x}{3}=\frac{x+2}{2}[/tex]
* These are two equivalent fractions
we can solve by using cross-multiplication way
that means we multiply x by 2 and multiply (x + 2) by 3
∴ 2(x) = 3(x + 2)
* Take care about the multiplication of 3(x + 2) you must
multiply 3 by x and also multiply 3 by 2
∴ 2x = 3x + 6
* Now lets start to collect the like terms
∴ 2x - 3x = 6
∴ -x = 6
* Divide the both sides by -1
∴ x = -6
x = -3/2 (Or) x = -1.5
First apply the rule a/a = 1
2/2 = 1
x/3 = x +1
Multiply both sides by 3
(x/3 * 3) = (x * 3) + (1 * 3)
Simplify
x = 3x + 3
Subtract 3x from both sides
(x - 3x) = (3x + 3 - 3x)
Simplify
-2x = 3
Divide both sides by -2
(-2x / -2) = (3 / -2)
Simplify
x = -3/2
(Decimal: x = -1.5)

please help me find the surface area of the triangular prism ( number 3)
Check the picture below.
so the triangular prism is really 3 rectangles and two triangles stacked up to each other at the edges, so if we simply get the area of each figure individually and sum them up, that's the area of the prism.
let's notice, the triangles have a base of 2.4 and a height/altitude of 1.
[tex]\bf \stackrel{\textit{2 triangles's area}}{2\left[ \cfrac{1}{2}(2.4)(1) \right]}~~+~~\stackrel{\textit{right rectangle}}{(2\cdot 1.5)}~~+~~\stackrel{\textit{left rectangle}}{(2\cdot 1.7)}~~+~~\stackrel{\textit{bottom rectangle}}{(2\cdot 2.4)} \\\\\\ 2.4+3+3.4+4.8\implies 5.4+8.2\implies 13.6[/tex]
What is the solution of the system of equations?
y = x - 10
y = 2x + 5
Final answer:
To solve the system of equations y = x - 10 and y = 2x + 5, we equate both expressions for y, solve for x, and find x = -15. Substituting x back into either equation gives y = -25, making the solution (x, y) = (-15, -25).
Explanation:
The question seeks the solution of the system of equations given by y = x - 10 and y = 2x + 5.
To find the solution, one can use the substitution method, where the expression for y in one equation is substituted into the other equation.
This gives us two equations stated to have the same value of y, which means they can be set equal to each other: x - 10 = 2x + 5.
Solving this equation for x involves moving x terms to one side and constants to the other, yielding x = -15. Substituting x back into either original equation (e.g., y = x - 10), we find y = -25.
Thus, the solution to the system of equations is x = -15 and y = -25.
What is the area of the trapezoid?
Answer:
Hi there!
I got the answer: 88 units^2
Step-by-step explanation:
to find the area you the formula: A=(a+b)/2 times height
"a" in this case is 17 and "b" is 27 because 5+5+17 is 27
height is 4
then you plug what you know into the equation
(17+27)/2 times 4 to get 88
What is the measure of an arc intercepted by an inscribed angle whose measure is 88 degrees
44
88
176
None of the above
Answer:
[tex]176\°[/tex]
Step-by-step explanation:
we know that
The inscribed angle is half that of the arc it comprises.
so
In this problem
Let
x-----> the measure of an arc intercepted by an inscribed angle
[tex]88\°=\frac{1}{2}(x)[/tex]
[tex]x=2(88\°)=176\°[/tex]
Option (C) The intercepted arc of an inscribed angle measuring 88 degrees has a measure of 176 degrees, which is twice the size of the inscribed angle according to the Angular Measurement of Arcs property.
The measure of an arc intercepted by an inscribed angle is twice the measure of the inscribed angle. Given that the inscribed angle measures 88 degrees, the intercepted arc would therefore measure 176 degrees. This is because according to the Angular Measurement of Arcs property, an arc's measure is twice that of its corresponding inscribed angle (Theorem 7 in the reference material).

Jen slices a cone with a height of 10 centimeters and a radius of 4 centimeters using a plane that is perpendicular to the base and that passes through the vertex of the cone. What is the area of the cross-section in square centimeters?
A cone that is sliced through the vertex would make the shape of a triangle.
You are told the h eight is 10 cm and the radius is 4 cm.
The radius would be half the base, so the base would be 4 * 2 =8 cm.
The area of the triangle is found by multiplying the base by the height, then dividing by two.
Area = 8 x 10 = 80
80 / 2 = 40 square centimeters.

A child’s pool is in the shape of a rectangular prism with a height of 2 ft and a base that is 4 ft wide by 5 ft long. During the course of the summer, the child’s pool needed to be filled 3 times.
How many cubic feet of water were needed to fill the pool during the summer?
A. 40 ft³
B. 80 ft³
C. 120 ft³
D. 160 ft³
Answer:
C. 120 ft^3
Step-by-step explanation:
Area of rectangular prism is Length * Width * Height.
4 * 5 * 2 = 40
It was filled 3 times so multiply 40 by 30
40 * 30 = 120 ft^3
Please help me answer this question!!! and explain bc im very stupid and my grades are low. 15 points
Answer:
17
Step-by-step explanation:
The top angle is 90 degrees, so I would assume that m<1 is 90 degrees. Plugging this into the equation gives us 90 = 4y + 22. Subtract 22 from both sides, and we get 68 = 4y. Divide both sides by 4, and we get 17 = y.

Prove: If a chord of a circle makes an angle of 30° with a diameter, prove that the distance from the center to the chord is one-fourth the length of the diameter.
Answer:
See explanation.
Step-by-step explanation:
Let BC be the diameter of the circle with center at point O, AB be the chord and ∠ABC=30°. OD is the distance from the center to the chord.
Consider triangle BDO. This triangle is special 30°-60°-90° right triangle. The leg OD is opposite to the angle of 30° and is half of the hypotenuse. The hypotenuse of the triangle BDO is BO. BO is the radius of the circle and is equal to half of the diameter AB. Thus,
[tex]OD=\dfrac{1}{2}BO=\dfrac{1}{2}\cdot \dfrac{1}{2}AB=\dfrac{1}{4}AB.[/tex]

Question 3 mathematics
Answer:
Part a) The area of the shaded region is [tex]41\ ft^{2}[/tex]
Part b) The area of the nonshaded region is [tex]87\ ft^{2}[/tex]
Step-by-step explanation:
we know that
The total area is equal to the area of the shaded region plus the area of the nonshaded region
step 1
Find the total area
The total area is equal to the area of the rectangle
[tex]A=8(16)=128\ ft^{2}[/tex]
step 2
Find the area of the shaded region
The area of the shaded region is equal to the area of the trapezoid minus the area of the smaller square
so
[tex]A=\frac{1}{2}[(8-2)+3)](8+2) -2^{2} \\ \\A=\frac{1}{2}[9](10) -4\\ \\A=41\ ft^{2}[/tex]
step 3
Find the area of the nonshaded region
The area of the nonshaded region is equal to the total area minus the area of the shaded region
so
[tex]A=128\ ft^{2}-41\ ft^{2}=87\ ft^{2}[/tex]
The ratio of the perimeters of two rectangles is 5 to 8 . the perimeter of the larger rectangle is 72 inches. What is the perimeter of the smallest triangle?
ANSWER
45 inches.
EXPLANATION
Let the perimeter of the smaller rectangle be x.
Then, the ratio of the perimeter of the smaller rectangle to the larger rectangle is
[tex]x:72=5:8[/tex]
We change the ratio to fraction to obtain,
[tex] \frac{x}{72} = \frac{5}{8} [/tex]
Multiply both sides by 72.
[tex]x = \frac{5}{8} \times 72[/tex]
[tex]x = 5 \times 9 = 45[/tex]
The perimeter of the smaller rectangle is 45 inches.
Answer:
45 inches
Step-by-step explanation:
The 72 inches is 8 parts of the ratio, hence
[tex]\frac{72}{8}[/tex] = 9 inches ← 1 part of the ratio
5 parts = 5 × 9 = 45 inches ← smaller perimeter

Solve
b = 3/4a
a + b = 21
Answer:
(12, 9)
Step-by-step explanation:
Please enclose fractions inside parentheses in cases such as this one. You meant b = (3/4)a, not b = 3/(4a).
To solve this system, subst. (3/4)a for b in the 2nd equation, obtaining:
a + (3/4)a = 21.
Mult. all 3 terms by 4 to eliminate the fraction 3/4:
4a + 3a = 84
combining like terms: 7a = 84
Solving for a: a = 84/7 = 12.
If a = 12, b = (3/4)a = (3/4)(12) = 9
The solution is (12, 9)
Answer:
a=12
b=9

Jessica bought 10 pieces of candy at the store. She spent $8.60. How much did each piece of candy cost?
Answer:
Each piece of candy cost
$0.86
Step-by-step explanation:
Step one This problem bothers on well we can do and understand our division of numbers
Step two
Given that Jessica spent $8.60
To buy 10 pieces of candy
Step three
We can get the unit cost of each candy by simply divide the total amount spent by the total Candy purchased
Hence
A candy cost = 8.60/10
= $0.86
