ASAP PLEASE HELP!! SCALE FACTOR! EASY!!

Answer:

a) 50.24 ft²

b) 150.72 ft²

Step-by-step explanation:

Jason is painting a large circle on one wall of his new apartment. The largest distance across the circle will be 8 feet.

The distance across a circle is also called a diameter, Hence,

D = Diameter = 8 ft

The Area of a circle = πr²

r = Diameter/2 = 8ft/2 = 4ft

π = 3.14

Hence,

The Area of the circle = π × (4 ft)²

= 50.24 ft²

a) Approximately the amount of wall the circle will cover is 50.24 ft².

b) How much area will he cover if he painted a circle on three walls?

This is calculated as:

1 wall = 50.24 ft²

3 walls = x

Cross Multiply

x = 3 × 50.24 ft²

x = 150.72 ft²

Answer:

the answer is E. none of the above

Step-by-step explanation:

not sure im so sorry!

i can't see the 4th option but from what i can see, i'd say 20 (b).

i didn't do math for this, i just used context clues.

the hypotenuse is always longer than either of the sides, so if the hypotenuse is 29, then the only logical solution is 20 feet. every other option is >29.

Answer:

Hello! answer: 20 feet

Step-by-step explanation:

29 × 29 = 841 21 × 21 = 441 841 - 441 = 400 √400 = 20 20 × 20 = 400 therefore 20 is the answer Hope that helps!

Answer:

252 cm^3

Step-by-step explanation:

The volume of a rectangular prism is denoted by the formula:

V = lwh

We can substitute in the values to get:

V = 7 x 12 x 3

V = 252 cm^3

Answer:

The answer of this question is 8.06 cm.

Step-by-step explanation:

I came to know my answer is correct because hypotenuse is bigger than base and perpendicular in right anhled triangle.

Answer:

2.4 x 10²

Step-by-step explanation:

1.44/6 x 10^8-5 = .24 x 10³ which is 240

Answer:

11.6

Step-by-step explanation:

a^2 + b^2 = C^2

121 + b^2=  256

b^2 = 135

b = 11.6

Answer:

x = -1   y = 3

Step-by-step explanation:

x + (x + 4) = 2

x + x + 4 = 2

2x = -2

x = -1

y = -1 + 4

y = 3

Answer:

y = 3

x = - 1

Step-by-step explanation:

x + y + x + 4 = y + 2

x + y - y + x + 4 = y - y + 2

x + x + 4 = 2

2x + 4 = 2

2x + 4 - 4 = 2 - 4

2x = - 2

2x ÷ 2 = - 2 ÷ 2

x = - 1

y = x + 4

y = - 1 + 4

y = 3

Answer:

Emily is solving the following system of equations using substitution:

y = 3x - 4

y = 2x + 1

Part A:

After substituting y's values:

3x - 4 = 2x + 1

What she did:

3x - 4 = 2x + 1

3x + 2x - 4 = 1

5x - 4 = 1

What she should have done:

3x - 4 = 2x + 1

3x - 2x - 4 = 1

x - 4 = 1

Part B:

This rule has not been followed: Sign changes when numbers shift from left to right of ' = 'sign.

Emily did not changed the sign of the number, 2x from + 2x to - 2x when it was moved from the right side to the left.

Answer:

86.1 I believe because I'm assuming you meant 2.87

0 solutions.

4x+2 is not = 4x+6

Therefore there will be Jo solutions

Answer:

no solutions

Step-by-step explanation:

Given the 2 equations

y = 4x + 2 → (1)

y = 4x + 6 → (2)

Substitute y = 4x + 2 into (2)

4x + 2 = 4x + 6 ( subtract 2 from both sides )

4x = 4x + 4 ( subtract 4x from both sides )

0 = 4 ← not possible

This indicates the system has no solution

Step-by-step explanation:

[tex] {2x}^{2} + 8x - 1 = 0 \\ {x}^{2} + 4x - \frac{1}{2} = 0 \\ {x}^{2} + 4x + {( \frac{1}{4} )}^{2} - \frac{1}{2} - { (\frac{1}{4} )}^{2} = 0 \\ {(x + \frac{1}{4}) }^{2} - \frac{9}{16} = 0 \\ {(x + \frac{1}{4}) }^{2} = \frac{9}{16} \\ x + \frac{1}{4} = ±( \frac{ 3}{4} ) \\ x = \frac{1}{2} \: or \: - 1[/tex]

Answer:

Step-by-step explanation:

divide each term by 2 to begin with x²

x² + 4x - 1/2 = 0

now add 1 to each side

x² + 4x = 1/2

now divide 4 in half and square the result and add it to each side

x² + 4x + 4 = 1/2 + 4

(x + 2)² = 9/2

Answer:

angle P=38°

angle Q = 38° [ Because this traingle is a isosceles triangle]

Step-by-step explanation:

This is just a guess I haven't done this in a long time

Take the Initial Angle ( 164 degrees )

subtract that from 180

you get 16

since the two unknown angles are parallel they are going to have the same angle

since there are two you divide 16 by 2

each angle is 8 degrees
