A. 34
f(5)=5^2+2x-1
you replace all x with 5
5^2=25
2(5)= 10
f(5)=25+10-1
f(5)=34

3. Connie bought several types of candy for Halloween: Milky Ways, Tootsie Rolls,

devlian [24]

Answer:

Tootsie Rolls = 13

Step-by-step explanation:

Given:

Milky Ways and Tootsie Rolls together were 15 more than the number of Reese's Cups.

There were 4 fewer Reese's Cups than Hershey Bars.

There were 12 Milky Ways and 14 Hershey Bars.

Solution

Milky Ways and Tootsie Rolls = Reese's Cups + 15

There were 4 fewer Reese's Cups than Hershey Bars.

Hershey Bars = 14

Then,

Reese's Cups = 14 - 4

= 10

Milky ways = 12

Hershey bars = 14

Reese's Cups = 10

Milky ways = 12

Milky Ways + Tootsie Rolls = Reese's Cups + 15

12 + Tootsie Rolls = 10 + 15

12 + Tootsie Rolls = 25

Subtract 12 from both sides

Tootsie Rolls = 25 - 12

= 13

Tootsie Rolls = 13

A company makes wax candles in the shape of a solid sphere. Suppose each candle has a diameter of 15 cm. If

jekas [21]

We have been given that a company makes wax candles in the shape of a solid sphere. Each candle has a diameter of 15 cm. We are asked to find the number of candles that company can make from 70,650 cubic cm of wax.

To solve our given problem, we will divide total volume of wax by volume of one candle.

Volume of each candle will be equal to volume of sphere.

$V=\frac{4}{3}\pi r^3$ , where r represents radius of sphere.

We know that radius is half the diameter, so radius of each candle will be $\frac{15}{2}=7.5$ cm.

$\text{Volume of one candle}=\frac{4}{3}\cdot 3.14\cdot (7.5\text{ cm})^3$

$\text{Volume of one candle}=\frac{4}{3}\cdot 3.14\cdot 421.875\text{ cm}^3$

$\text{Volume of one candle}=1766.25\text{ cm}^3$

Now we will divide 70,650 cubic cm of wax by volume of one candle.

$\text{Number of candles}=\frac{70,650\text{ cm}^3}{1766.25\text{ cm}^3}$

$\text{Number of candles}=\frac{70,650}{1766.25}$

$\text{Number of candles}=40$

Therefore, 40 candles can be made from 70,650 cubic cm of wax.
