Step-by-step explanation:      

<u>Step 1: Simplify</u>

4+9x^2/3 - 1

=4+3x^2+-1

<u>Step 2: Combine Like Terms:</u>

= 4+3x^2+1-1

= (3x^2)+(4+-1)

Answer: = 3x^2+3

Explanation in words (Short Form)

-  The first step is to use the formula and simplify it. So first we will Rewrite the division as a fraction.

- The second step is to Cancel the common factor of 9 and 3. Then Factor 3 out of 3. After that Cancel the common factor.

- The third step is to divide 3x^2 by 1. Then at the end, subtract 1 from 4. The answer will result as 3x^2+3

Answer:    

=3x^2+3

Hope this helps.

Question 11
dem82 [27]

Answer:

There were 49 questions on this Geometry test.

Step-by-step explanation:

You can start by setting up a proportion:

x = total number of questions on Geometry test

\frac{37}{x} = \frac{75.51}{100}

Now, to solve for x, cross multiply:

75.51x = 3700

Finally, isolate x and solve:

x = 49.0001324328

This is very close to 49.

Given the speeds of each runner below, determine who runs the fastest. \text{Debbie runs 15 feet per second.} Debbie runs 15 fee
grin007 [14]

Answer:

Debbie

Step-by-step explanation:

Remember that

1 mile=5,280 ft

1 minute=60 seconds

In order to be able to compare all the speeds, we are going to unify the units to feet per second

we have

1) Debbie runs 15 feet per second

15\frac{ft}{sec}

2) Liz runs 112 feet in 11 seconds

Divide the distance by the time to find the unit rate

\frac{112}{11}=10.18\frac{ft}{sec}

3) Stephanie runs 1 mile in 411 seconds

Convert to feet per second

\frac{1}{411}\frac{mi}{sec}=\frac{1*(5,280)}{411}=12.85\frac{ft}{sec}

4) Tony runs 581 feet in 1 minute

Convert to feet per second

\frac{581}{1}\frac{ft}{min}=\frac{581}{60}=9.68\frac{ft}{sec}

therefore

The fastest is Debbie because her speed is greater than the other runners.

15\frac{ft}{sec}>12.85\frac{ft}{sec} > 10.18\frac{ft}{sec} > 9.68\frac{ft}{sec}
