Answer:

The measure of angle a is 45 degrees.

Step-by-step explanation:

Notice that since PS = RS, this is an isosceles triangle. This means that the base angles are equal. We also know that the sum of interior triangles of a triangle equals 180, then, if 'a' is the base angle, we have the following equation:

90 + a + a = 180

2a = 180 - 90 = 90

a = 90/2 = 45

a = 45

Melanie uses 8.1 pints of blue paint and white paint to paint her bedroom walls. 2/5 of this amount is blue paint, and the rest
attashe74 [19]

Answer:

4.86

Step-by-step explanation:

Melanie uses 8.1 pints of blue paint and white paint for her bedroom

2/5 of this amount is blue paint

Therefore the amount of white paint can be calculated as follows

= 2/5

= 0.4×100

= 40%

60/100 × 8.1

= 0.6 × 8.1

= 4.86

Hence 4.86 pints of white paint will be used to paint the bedroom

Can i please get help on this Question?
Shalnov [3]
Hi there!

Given:
4m +  \frac{23 + n}{p - 3}  \\ m = 7 \\ n = 2 \\ p = 8

In order to evaluate the expression with the given values of m, n and p, we must substitute then into the expression. Then we use the correct order of operations (PEMDAS) to calculate.

Let's substitute first!
4(7)  +  \frac{(23 + 2)}{(8 - 3)}

Now find the numerator and denominator of the fraction.
4(7) +  \frac{25}{5}

Next up: multiplying
28 +  \frac{25}{5}

Divide the fraction.
28 + 5

And finally add the integers.
33

Hence, the answer is 33.
~ Hope this helps you!

Help, question is below :)))
qaws [65]

Answer:

$43 million

Step-by-step explanation:

<h3>Step 1. Turn the sentence into an equation (total = T)</h3>

15.4 million = 0.36 (T)

<h3>Step 2. Solve for T </h3>

15,400,000 / 0.36 = T

42,777,777.78 = T

$42.8 million ≈ $43 million (rounded)

The final answer rounded to the nearest million is $43 million. This makes sense since $15.4 was only 36% of this total. Checking our math, 36% of $43 million is $15.4 million!

Hope this helps :)
