The cost (c) to buy gasoline for a car varies directly to the amount of gas (g) in gallons purchased. Helen spent $16.72 on 8 gallons of gas for her car. Nathan is buying the same gasoline, but only has $10.45 to spend. How many gallons of gas can Nathan buy? How do you know?​
Answer:
5 gallons
Step-by-step explanation:
1) How much did Helen spend per gallon?
16.72/8 = $2.09/gallon
2) 2.09g = 10.45
10.45/2.09 = g

what is an equation of the line in the slope- intersepct is (0,3)
Answer:
using the formula x/a + y/b =1
a: slope intercept on the x axis
b:slope intersect on the y axis
x/0 + y/3 = 1 (since x/0 is undefined ,the slope doesn't exist and it is impossible for a slope to be linear)

Step-by-step explanation:
Sn = n/2(2a+(n-1)d)
a=6
a+ 4d= 18
6 +4d= 18
4d = 12
d = 3
162= n/2(12+(n -1)3)
324=n(12 + 3n-3)
324=12n + 3n^2 - 3n
3n^2 + 9n-324=0
3n^2+ 36n-27n -324 =0
3n(n+12) -27(n+12)= 0
3n-27 =0; n+ 12=0
n=9 ; n= -12
since n can't be negative n=9
The number of terms is 9

The value of the function g(h(10)) will be 2√2.
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given that g(x) is √(x-4) and h(x) is 2x - 8. The value of the function g(h(10)) will be calculated as:-
h(x) = 2x - 8
At x = 10 the value of the function h(x) will be:-
h(10) = ( 2 x 10 ) - 8
h(10) = 20 - 8
h(10 ) = 12
Calculate the value of the function g(h(10)):-
g(h(10)) = √(x-4)
g(h(10)) = √(h(10)-4)
g(h(10)) = √( 12 -4 )
g(h(10)) = √( 8 )
g(h(10)) = 2√2.
Therefore, the value of the function g(h(10)) will be 2√2.

At 109°F, a certain insect chirps at a rate of 77 times per minute, and at 117°F, they chirp 101 times per
minute. Write an equation in slope-intercept form that represents the situation.
The equation that represents this situation is
Answer:
y=3x-250
Step-by-step explanation:
Slope intercept form: y=mx+b
Step 1) to find slope, use (y2-y1)/(x2-x1)
(101-77)/(117-109) = 3
m = 3
Step 2) determine y-intercept (b)
109 * 3 = 327
77-327 = -250
b=-250
y=3x-250

Based on the temperature change and the amount of time it did so, the average change in temperature per hour is -3.5°F.
The average change in temperature per hour can be found by:
= Temperature change / Number of hours
Solving would give:
= -23.8 / 6.8
= -3.5°F
We can therefore conclude that in every hour of this cold day, the temperature changed by an average of -3.5°F.

What is the angle measure for
Answer:
x = 6
∠PQR = 29
Step-by-step explanation:
Sum of interior angles in a triangle is 180,
15x - 4 + 4x + 5 + 65 = 180
15x + 4x + 5 - 4 + 65 = 180
19x + 1 + 65 = 180
19x + 66 = 180
19x = 180 - 66
19x = 114
x = 114 / 19
x = 6
∠PQR = 4x + 5
Substitute x = 6,
∠PQR = 4 ( 6 ) + 5
= 24 + 5
∠PQR = 29

4. Each morning you do a combination of aerobics, which burns about 12 calories per
minute, and stretching, which burns about 4 calories per minute. Your goal is to burn
416 calories during a 60-minute workout. How long should you spend on each type of
exercise to burn the 416 calories?
22 minutes is spent doing aerobics and 38 minutes doing stretching
Let x represent the amount of time spent doing aerobics, Let y represent the amount of time spent doing stretching.
Since the goal is to do a 60-minute workout, hence:
x + y = 60 (1)
Also, 416 calories needs to be burnt hence:
12x + 4y = 416 (2)
We need to solve equation 1 and 2 simultaneously; multiply equation 1 by 4 and subtract the result from equation 2, hence:
8x = 176
x = 22 minutes
Put x = 22 in (1)
22 + y = 60
y = 38 minutes
Therefore 22 minutes is spent doing aerobics and 38 minutes doing stretching.
