Suppose that the distance a car travels varies directly with the amount of gasoline it uses. A certain car uses 8 gallons of gasoline to travel 232 miles. If the car travels 435 miles, how much gasoline does it need? gallons $ ?
Answer:
Mileage ÷ Gallons= Miles per gallon.
232 miles ÷ 8 Gallons = 29 miles per gallon
Mileage÷ Miles per gallon= Gallons
435 miles÷ 29 miles per gallon= 15 gallons
as for the $ sign, that variable is not there.

In one region, the September energy consumption levels for single-family homes are found to be normally distributed with a mean of 1050 kWh and a standard deviation of 218 kWh. For a randomly selected home, find the probability that the September energy consumption level is greater than 1100 kWh.
Please show work!
Answer:
0.4093
Step-by-step explanation:
A suitable probability calculator will answer this question with no "work" required, other than to enter the numbers into the calculator. The attachment shows the probability of interest is about 0.4093 that consumption will exceed 1100 kWh.
__
Additional comment
All spreadsheets have probability functions built in. Many graphing calculators are similarly capable of giving area from probability, or probability from area. A TI-84 requires two limits. In most cases, an upper limit of about 10 standard deviations from the mean (here, 3000 kWh) will work just fine. It tells me ...
normalcdf(1100,3000,1050,218) = 0.409295417
This is in agreement with my phone app: 0.4092954170395281.

What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
A square and a rectangle are in the given figure.
Now,
Square:
Side = 5 ft
Area = Side² = 5² = 25 ft²
Rectangle:
Length = 3 ft
Wide = 2 ft
Area = 3 x 2 = 6 ft²
Now,
Total area:
= 25 + 6
= 31 ft²
Thus,
The total area is 31 ft².

if n = 11 and p = 5 what is the value of the expression 18 - n - 2 + p
Answer:
10
Step-by-step explanation:
If n = 11 and p = 5, we can just substitute the values in for n and p in the equation 18 - n - 2 + p.
The new equation would be 18 - 11 - 2 + 5.
Using PEMDAS, we get the answer of 10.
18 - 11 = 7
7 - 2 = 5
5 + 5 = 10

We are given arc KL is 12x+4, arc KJ is 8x-6, and angle E is 99 degrees. What is the measure of angle K?
46 degrees
74 degrees
81 degrees
99 degrees
Answer:
81°
Step-by-step explanation:
m(arc)JKL = 2m<E = 2(99°) = 198°
m(arc)JEL = 360° - m(arc)JKL
m(arc)JEL = 360° - 198° = 162°
m<K = (1/2)m(arc)JEL = 162°/2 = 81°
The length and breadth of a room are in in the ratio of 3:2
Find the length of breadth is 8.6 meters
Answer:
12.9 m
Step-by-step explanation:
Let length = 3x, then breadth is 2x
if breadth is 8.6 m, so 2x = 8.6 m, x = 8.6/2 = 4.3 m
length = 3x = 3* 4.3 = 12.9 m

Answer:
x > 7
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
[tex]-3x+5-5<-16-5[/tex] [tex]-3x<-21[/tex]Step 2: Divide both sides by -3.
[tex]-3x/-3<-21/-3[/tex] [tex]x>7[/tex]Therefore, the answer is x > 7.
Answer:
X = 6
Step-by-step explanation:

-18 < 21
X = 6 since -3x is -18 and negative cancels each other
