a). (20 x 80) + (20 x 6) + (7 x 80) + (7 x 6)
Answer:
D. 17.4%
Step-by-step explanation:
To find a percent, divide the part by the whole and multiply by 100.
The part is the sum of Tim's Chevron and Car:
$23 + $272 = $295 = part
The total is $1695 = whole
percent = part/whole * 100%
percent = 295/1695 * 100%
percent = 0.174041 * 100%
percent = 17.4%
Answer: D. 17.4%
By using a change of units, we can see that the rate in dollars per liter is:
R = $0.0027 per liter.
<h3>
How to convert the rate?</h3>
Here we have a rate in dollars per cubic foot, and we want to rewrite this in dollars per liter. So we just need to apply a change of units.
The original rate is in dollars per square foot, and it is given by:
R = $1.30 for 16.7ft^3
We know that the relation between cubic feet and liters is:
1ft^3 = 28.32 L
Then, if we apply a change of units, we can rewrite the volume as:
16.7ft^3 = 16.7*(28.32) L = 472.9 L
Then the rate is $1.30 per 472.9 L, taking the quotient we get:
R = ($1.30/472.9 L) = $0.0027 per liter.

Answer:
B. f(x) domain: x ≥ 1; f⁻¹(x) range: y ≥ 1
Step-by-step explanation:
The <em>domain</em> of a function is identical to the <em>range</em> of its inverse. This is reflected in choices B and D. However, f(x) is undefined for x < 1, so it makes no sense to restrict its domain to x ≤ -2, as in choice D.
The appropriate response is ...
B.
- f(x) domain: x ≥ 1
- f⁻¹(x) range: y ≥ 1
Answer:
Nikki grows 20 tomato plants and she measures their heights.
We want to complete the frequency table.
All we have to do is count the number of values that fall between each range.
The values are:
5 10 12 16 14
17 20 15 10 7
13 11 6 18 15
6 12 17 8 12
Height Frequency
-> 5 ≤ h < 10 5
10 ≤ h < 15 8
15 ≤ h < 20 6
20 ≤ h < 25 1
