Answer:

<A = 63degrees

Step-by-step explanation:

From triangle DEF;

<D + <E + <F = 180

87 + 30 + <F = 180

117 + <F = 180

<F = 180 - 117

<F = 63degrees

Since <A = <F based on similarities, then <A = 63degrees

A cat weighs 8 1/4 pounds.

Brilliant_brown [7]

8 1/4 pounds converted to ounces is 132 ounces. 1 pound is 16 ounces, so all you have to do is multiply the number of pounds by 16.

(8,-7)m=-3/4 write an equation in point slope form of the line that passes through the given point and has the given slope

Paladinen [302]

Answer:

Equation of the straight line in point-slope form

y -(-7) = $\frac{-3}{4}$ (x-8)

Equation of the straight line

3x +4y +4=0

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the point ( 8,-7) and $m = \frac{-3}{4}$

Equation of the straight line passing through the point (x₁, y₁) and having slope 'm'

y - y₁ = m (x-x₁)

y -(-7) = $\frac{-3}{4}$ (x-8)

4( y+7) = -3(x-8)

4y +28 = -3x +24

3x +4y +28 -24 =0

3x +4y +4=0

Austin buys 30 cups he places 4 balls in each cup how many cups does he need

ollegr [7]

I think you misworded this question. If he buys 30 cups and puts four balls in each, then he would still have 30 cups.
