Answer:

B = $\frac{4}{9}$ A

Step-by-step explanation:

Given that B varies directly as A then the equation relating them is

B = kA ← k is the constant of variation

To find k use the condition A = 90 and B = 40, then

k = $\frac{B}{A}$ = $\frac{40}{90}$ = $\frac{4}{9}$

B = $\frac{4}{9}$ A ← equation of variation

(3x + 5)° + (10x - 7)° = 180°

13x + (-2) = 180

13x = 180 + 2

13x = 182

x = 14

∠QRT = 3 * 14 + 5 = 42 + 5 = 47°

∠TRS = 10 * 14 - 7 = 140 - 7 = 133°

The chart below summarizes Ralph's annual expenses for the upcoming year. Based on the information in the graph, approximately w

kenny6666 [7]

Answer:

The Federal taxes of total budget is 30%

C is correct.

Step-by-step explanation:

The chart below summarizes Ralph's annual expenses for the upcoming year.

We need to find the percentage for federal taxes.

First we find total annual budget from chart. We will add all the taxes.

Total annual budget = Federal taxes + State tax + Housing + Food + Medical +

Transportation + Recreation

Total Annual Budget = 18380 + 3448 + 15000 + 4880 + 6652 + 4332 + 3500 +

3260 + 1750

= 61202

Total Annual Budget = $61,202

Federal Taxes = $18,380

Now, we will find the percentage of federal taxes.

% of federal taxes $=\dfrac{18380}{61202}\times 100$

$=30.03\approx 30\%$

Hence, The Federal taxes of total budget is 30%

Consider the function f(x)= x² - 4

Arisa [49]

Answer:

(X+2) (X-2) . This is the final answer

Step-by-step explanation:

Solving f(x) = x^2 - 4

A^2 - B^2 is a special case where the original equation before it was foiled is

(A + B) (A - B) because the middle terms will cancel out when foiled.

This means that the equation can be written as

(X + 2)(X - 2) = 0

Each of these you will then set equal to 0 and then solve

X + 2 = 0, X - 2 = 0

X = -2, 2

I hope this helps you! let me now if its right ok <3 :)
