Answer:
100°
Step-by-step explanation:
The sum of all the angles in a triangle is 180°.
This is 1 + 3 + 5 = 9
180 ÷ 9 = 20
The scale factor is 20.
Multiply 5 (the greatest angle) by the scale factor.
5 x 20 = 100
Solve: 4n - 6 = 12
O n = 4
O n = -4
O n = 4.5
O n=-4.5
Answer:
4.5
Step-by-step explanation:
4n - 6 = 12
add +6 to both sides
4n = 18
divide by 4
4/4n = 18/4
n = 4.5

the width if a rectangular room is 1 less than twice the length if the perimeter is 196 feet how long is the length
Answer:
l = 33 feet
Step-by-step explanation:
Let length be l.
Width, b = 2l-1
Perimeter of the room, P = 196
We know that the perimeter of the rectangle is given by :
P = 2(l+b)
196=2(l+2l-1)
98=3l-1
Adding 1 both sides.
98+1=3l-1+1
3l=99
l = 33 feet
So, the length of the room is 33 feet.

Find the area of the
triangle.
Answer:
472.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
Base (b) = 30 yd
height (h) = 31.5 yd
Area of the triangle
= 1/2 * b * h
= 1/2 * 30* 31.5
=472.5 yd²
7th grade please solve the problem above. Write a paragraph explaining how you found the solution you must include each step for solving please!!!
Answer:
x=0
Step-by-step explanation:
You must isolate the variable to solve for it, so subtracting 14 from the left is the first thing to do. This can be supported by using PEMDAS, whereas we are doing the inverse here to solve for something in the equation. This gives us 2x=0. Next, we have to divide by 2, which gives us x=0.
solve the system using the any method:
x+3y=9
2x+5y=14

Answer:
11
Step-by-step explanation:
The future value of the account is given by the formula ...
A = P(1 +r/12)^(12t) . . . . principal P invested at rate r for t years
Solving for t, we find ...
A/P = (1 +r/12)^(12t) . . . . . . . . . . . divide by P
log(A/P) = 12t·log(1 +r/12) . . . . . . take logs
Divide by the coefficient of t, then fill in the numbers.
t = log(A/P)/(12·log(1 +r/12)) = log(202800/93000)/(12·log(1 +.068/12))
t ≈ 11.497
It will take about 11 years for the account balance to reach the desired amount.

How to tell the difference between multiplication and division word problems?
Answer:
Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction and division. The result of a multiplication operation is called a product. And division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication

What is X for brainliest
Answer:
the value of x is 2
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
Given 3 parallel lines intersected by 2 transversals then the parallel lines divide the transversals proportionally, that is
[tex]\frac{3x}{4}[/tex] = [tex]\frac{7.5}{2.5x}[/tex] ( cross- multiply )
7.5x² = 30 ( divide both sides by 7.5 )
x² = 4 ( take the square root of both sides )
x = [tex]\sqrt{4}[/tex] = 2
Find the value of x.

Mary has 3636 flower pots. She plants daisies in \frac{2}{3} 3 2 of her flower pots. In how many flower pots does Mary plant daisies? Use paper to show your work. Enter your answer in the box.
Answer: 24
Step-by-step explanation:
Number of flower pots = 36
Since she plants daisies in 2/3 of her flower pots, the number of flower pots that Mary plant daisies will be:
= 2/3 × 36
= 2 × 12
= 24
She plants daises in 24 flower pots

Find the marked prices of the following , given the percentage discount and the sale prices: part a: 12% discount , and the sale price $77
part b : 25% discount , and the sale price $123
Answer:
A) $87.5
B) $164
Step-by-step explanation:
A) Marked Price (Original Price)
= [tex]\frac{Sale Price}{1 -Discount}[/tex]
=[tex]\frac{77}{1-0.12}[/tex]
=87.5
B) Marked Price (Original Price)
=[tex]\frac{Sale Price}{1 -Discount}[/tex]
=[tex]\frac{123}{1-0.25}[/tex]
=164
14.Find the value of <A in the following figure.
Given:
The figure of triangle ABC.
To find:
The measure of angle A.
Solution:
From the given figure, we get
[tex]\angle ABC+120^\circ=180^\circ[/tex] (Linear pair)
[tex]\angle ABC=180^\circ-120^\circ[/tex]
[tex]\angle ABC=60^\circ[/tex]
According to the exterior angle theorem, the exterior angle of a triangle is equal to the sum of two opposite interior angles.
[tex]\angle A+\angle ABC=105^\circ[/tex] (Exterior angle theorem)
[tex]\angle A+60^\circ=105^\circ[/tex]
[tex]\angle A=105^\circ-60^\circ[/tex]
[tex]\angle A=45^\circ[/tex]
Therefore, the measure of angle A is 45 degrees.

The perimeter of a square is given as 8x+20. Write two different expressions for the perimeter. Use factoring to write one of the expressoins. Are the expressions equivalen? Explain
Answer:
P = 4(2x + 5)
P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)
Step-by-step explanation:
Given that:
Perimeter of square = 4 * s
Where s = side length
If perimeter, P = 8x + 20
Then,
4s = 8x + 20
Divide both sides by 4
4s / 4 = (8x + 20) / 4
s = 2x + 5
P = 4s
P = 4(2x + 5)
Or
P = 2x + 5 in 4 places
P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)
