The nitro-methane fuel mixture used to power some experimental cars is 96% nitrogen dioxide and 4% methane. How many gallons of methane are needed to fill a 15-gallone fuel tank?
Answer:
0.6 gallons of methane are needed to fill a 15-gallone fuel tank.
Step-by-step explanation:
Methane is 4% of the total amount.
The total amount is of 15 gallons. So
0.04*15 = 0.4*1.5 = 0.6
0.6 gallons of methane are needed to fill a 15-gallone fuel tank.

Answer:
c. 11
Step-by-step explanation:
By the property of intersecting secants outside of a circle, we have:
[tex] m\angle R = \frac{1}{2} \times (175\degree - 75\degree) [/tex]
[tex] m\angle R = \frac{1}{2} \times 100\degree [/tex]
[tex] (4x+6)\degree = 50\degree [/tex]
4x + 6 = 50
4x = 50 - 6
4x = 44

THE MEASURE OF TWO ADJACENT ANGLES OF THE PARALLELOGRAM ARE IN THE RATIO OF 3:2. FIND THE MEASURE OF EACH OF THE ANGLES OF THE PARALLELOGRAM
Answer:
The adjacent angles are: 72 and 108
Step-by-step explanation:
Given
Angle Ratio = 3 : 2
Required
Find the measure of each angle
Let the angles be [tex]x\ and\ y.[/tex]
Such that:
[tex]x + y = 180[/tex] --- adjacent angles of a parallelogram
and
[tex]x : y = 3 : 2[/tex] --- given
Convert to fraction
[tex]\frac{x}{y} = \frac{3}{2}[/tex]
Cross Multiply:
[tex]2x = 3y[/tex]
Make x the subject:
[tex]x = \frac{3}{2}y[/tex]
[tex]x + y = 180[/tex] becomes
[tex]\frac{3}{2}y + y = 180[/tex]
Take LCM
[tex]\frac{3y + 2y}{2}= 180[/tex]
[tex]\frac{5y}{2}= 180[/tex]
[tex]y = \frac{2}{5} * 180[/tex]
[tex]y = 0.4 * 180[/tex]
[tex]y = 72[/tex]
Recall that:
[tex]x = \frac{3}{2}y[/tex]
[tex]x = \frac{3}{2} * 72[/tex]
[tex]x = 1.5 * 72[/tex]
[tex]x = 108[/tex]
Hence, the adjacent angles are: 72 and 108

Cayden is 6 years older than Kaylee. If Cayden is y years old, and Kaylee is x years old, which of the following equations represents the relationship between their ages?
Answer: x + 6 = y OR y = x + 6 (same equation in different format)
Step-by-step explanation: If x represents Kaylee’s age, and Cayden is 6 years older, then you must always add 6 to Kaylee’s age in order to find Cayden’s age (y).
Answer:
x + 6 = y or y - 6 = x
Step-by-step explanation:
If you know that Cayden is 6 years older than Kaylee, then x (Kaylee's age) + 6 years = y (Cayden's age). You don't know the ages of them but you still know how much older Cayden is than Kaylee.
It can also be y - 6 = x because it shows that if you subtract 6 years from Cayden's age, you get Kaylee's age.
I don't know the options to this question but I hope this helps you :)

Doug earns $10.50 per hour working at a restaurant. On Friday he spent 1 3/4 hours cleaning, 2 1/3 hours doing paperwork, and 1 5/12 hours serving customers. What were Doug's earnings?A$46.97B$47.25C$53.00D$57.75
Answer:
$57.75
Step-by-step explanation:
The total hours spent working :
1 3/4 + 2 1/3 + 1 5/12
7/4 + 7/3 + 17/12
L.C.M = 12
(21 + 28 + 17) / 12

The sports shop has 30 part-time employees and 20 full-time employees. What percentage of the employees at the sports shop work part-time?
Answer:
the percentage of the employees at sports shop work part time is 60%
Step-by-step explanation:
The computation of percentage of the employees at sports shop work part time is shown below:
= Part time ÷ total employees
= 30 ÷ (20 + 30)
= 30 ÷ 50
= 3 ÷ 5
= 60%
Hence, the percentage of the employees at sports shop work part time is 60%
Solve each of these equations. Explain or show your reasoning. 2(3x+2)=2x+28 5y+13=-43−3y 4(2a+2)=8(2−3a)
Answer:
first equation=6
second equation=15
Third equation=
Step-by-step explanation:
2(3x+2)=2x+28
6x+4=2x+28
collect like terms
6x-2x=28-4
4x=24
Divide both sides by 4
4x/4=24/4
x=6
second equation
5y+13=43-3y
collect like terms
5y-3y=43-13
2y=30
Divide both sides by 2
2y/2=30/2
y=15
Third equation
4(2a+2)=8(2-3a)
8a+8=16-24a
collect like terms
8a+24a=16-8
32a=8
Divide both sides by 32
32a/32=8/32
a=1/4
1) The solution to the equation is x = 6.
2) The solution to the equation is y = -7.
3) The solution to the equation is a = 0.25
Given are three equations we need to solve for their variables,
1) 2(3x + 2) = 2x + 28
2) 5y + 13 = -43 - 3y
3) 4(2a + 2) = 8(2 - 3a)
Let's solve each equation step by step:
1) 2(3x + 2) = 2x + 28
Expanding the parentheses on the left side:
6x + 4 = 2x + 28
Next, let's isolate the variable terms on one side and the constant terms on the other side:
6x - 2x = 28 - 4
Combine like terms:
4x = 24
To solve for x, we need to isolate x by itself. Divide both sides of the equation by 4:
4x/4 = 24/4
x = 6
Therefore, the solution to the equation is x = 6.
2) 5y + 13 = -43 - 3y
Let's start by moving the variable terms to one side and the constant terms to the other side:
5y + 3y = -43 - 13
Combine like terms:
8y = -56
To solve for y, we divide both sides of the equation by 8:
8y/8 = -56/8
y = -7
Therefore, the solution to the equation is y = -7.
3) 4(2a + 2) = 8(2 - 3a)
First, distribute the multiplication on both sides:
8a + 8 = 16 - 24a
Next, let's group the variable terms on one side and the constant terms on the other side:
8a + 24a = 16 - 8
Combine like terms:
32a = 8
To solve for a, divide both sides of the equation by 32:
32a/32 = 8/32
a = 0.25
Therefore, the solution to the equation is a = 0.25.

What are the angle measures of each vertex of the garden? Show your work.
Answer:
m<a=36
m<b=175
m<c=92
m<d=93
m<e=144
Step-by-step explanation:
since the shape has 5 sides we can determine the sum of the measure of interior angels with the equation 180×(n-2). replacing n with 5 would bring us to 180×3 equalling 540. since all the angels must add up to 540 we can combine them together to get it to 15x=540. simplify to get x=36. sub in x in the equations.
