Answer:

13) A

14) B

15) C

16) C

Step-by-step explanation:

13)

Since the total number of seats, 18,000, is a combination of both the field and the grandstand seats, their number needs to be added together. Therefore, the equation is s+7,500=18,000.

14)

If you subtract 56 from both sides of the equation that you are given, you will be left with a=72.

15)

If you divide both sides of the equation by 2.4, you will be left with p=3.15.

16)

If you divide both sides of this equation by 2/3, you will be left with w=(3/4)/(2/3)=9/8 or 1 1/8 pounds. Hope this helps!

Sara drove 96 miles on 3.2 gallons of gas. How many miles can Sara drive on 12.5 gallons of gas
Blababa [14]

Answer:

375 miles

Step-by-step explanation:

Create a proportion where x is the number of miles she can drive on 12.5 gallons of gas:

\frac{96}{3.2} = \frac{x}{12.5}

Cross multiply and solve for x:

3.2x = 1200

x = 375

So, with 12.5 gallons of gas, Sara can drive 375 miles

Use the formula to evaluate the series 1+2+4+8+...a10
valina [46]

Answer:

The sum of the given series is 1023

Step-by-step explanation:

Geometric series states that a series in which a constant ratio is obtained by multiplying the previous term.

Sum of the geometric series is given by:

S_n = \frac{a(1-r^n)}{1-r}

where a is the first term and n is the number of term.

Given the series: 1+2+4+8+.................+a_{10}

This is a geometric series with common ratio(r) = 2

We have to find the sum of the series for 10th term.

⇒ n = 10 and a = 1

then;

S_n = \frac{1(1-2^{10})}{1-2} =\frac{1-1024}{-1} =\frac{-1023}{-1}=1023

Therefore, the sum of the given series is 1023
