So we know its a supplementary angle which is angles athat add up to 180 degrees since its a straight line.
Make an equation: 60+60+2x=180COmbine like terms
120+2x=180
subtract 120 on both sides
2x=60

Answer:
$8.97 and no decimal include in itWrite in slope-intercept form an equation of the line that passes through the given points (4, 1), (8, 2)
The slope-intercept form of the line is [tex]y=\dfrac{1}{4}x[/tex].
Given:
A line passes through the two points [tex](4,1)[/tex] and [tex](8,2)[/tex].
To find:
The slope-intercept form of the line.
Explanation:
The slope-intercept form of a line is:
[tex]y=mx+b[/tex]
Where, [tex]m[/tex] is slope and [tex]b[/tex] is the y-intercept.
The line passes through the two points [tex](4,1)[/tex] and [tex](8,2)[/tex]. So, the equation of the line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-1=\dfrac{2-1}{8-4}(x-4)[/tex]
[tex]y-1=\dfrac{1}{4}(x-4)[/tex]
Using the distributive property, we get
[tex]y-1=\dfrac{1}{4}(x)+\dfrac{1}{4}(-4)[/tex]
[tex]y=\dfrac{1}{4}x-1+1[/tex]
[tex]y=\dfrac{1}{4}x[/tex]
Therefore, the slope-intercept form of the line is [tex]y=\dfrac{1}{4}x[/tex].

What is the value of X
Answer:
The value of x is 15
Step-by-step explanation:
If a line intersected two parallel lines, then some pairs of angles are formed
Alternate interior angles, equal in measuresAlternate exterior angles, equal in measuresCorresponding angles, equal in measuresAdjacent interior angles, the sum of their measures is 180°In the given figure
∵ There are two parallel lines intersected by another line
∵ The angles of measures (4x + 2) and 62° are alternate interior angles
∴ Alternate interior angles are equal in measures
∴ 4x + 2 = 62
→ Subtract 2 from both sides
∵ 4x + 2 - 2 = 62 - 2
∴ 4x = 60
→ Divide both sides by 4
∴ x = 15
∴ The value of x is 15

Given constant temperature, P1 = 25 psia, P2 = 40 psia, and V1 = 30 cu in, what is V2 in cubic inches? Select one: a. 15 b. 17.5 c. 18.75 d. 33.33
Answer:
V2 = 18.75 cu in
Step-by-step explanation:
Given that:
Given constant temperature :
P1 = 25 psia, P2 = 40 psia, and V1 = 30 cu in,
Calculate v2
Using the relation :
Since Temperature T is constant ;
P1V1 = P2V2
25 * 30 = 40 * V2
750 = 40V2
V2 = 750 / 40
V2 = 18.75 cu in

9. The diameter of the Earth is 7899.83 miles from the North Pole to the South Pole and 7926.41 miles from opposite points at the equator.
a. Find the approximate surface area of Earth using each measure.
b. About 75% of Earth's surface is covered by water. Find the surface area of water on Earth, using the diameter of the Earth is 7926.41 miles from opposite points at the equator.
Answer:
a. The approximate surface area of the Earth based on the diameter of the Earth measured from the poles is approximately 1.961 × 10⁸ mi²
The approximate surface area of the Earth based on the diameter of the Earth measured from the equator is approximately 1.974 × 10⁸ mi²
b. The surface area of the water on Earth using the diameter of the Earth measured from opposite points of the equator is approximately 1.480 × 10⁸ mi²
Step-by-step explanation:
The given parameters are;
The diameter of the Earth measured from the North to the South pole, [tex]D_p[/tex] = 7899.83 miles
The diameter of the Earth measured from (across) opposite points of the equator, [tex]D_e[/tex] = 7926.41 miles
a. The surface area, [tex]A_E[/tex], of the Earth, taking the Earth as a perfect sphere, is given as follows;
A = 4 × π × r²
Where;
r = The radius of the sphere = 1/2 × the diameter of the sphere
For the diameter measured from poles, [tex]r_p[/tex] = [tex]D_p[/tex]/2 = (7899.83 miles)/2 = 3949.915 miles
The approximate surface area of the Earth based on the diameter of the Earth measured from the poles, [tex]A_{Ep}[/tex] = 4 × π × (3949.915 miles)² = 196058359.283 mi² ≈ 1.961 × 10⁸ mi²
For the diameter measured from equator, [tex]r_e[/tex] = [tex]D_e[/tex]/2 = (7926.41 miles)/2 = 3963.205 miles
The approximate surface area of the Earth based on the diameter of the Earth measured from the equator, [tex]A_{Ee}[/tex] = 4 × π × (3963.205 miles)² = 197379906.233 mi² ≈ 1.974 × 10⁸ mi²
b. The percentage of the surface area of the Earth covered by water ≈ 75%
The surface area of water on Earth using the diameter of the Earth = 7926.41 miles (the diameter measured from the equator), we have;
The area of the Earth with a diameter of 7926.41 miles was given as [tex]A_{Ee}[/tex] = 4 × π × ((7926.41 miles)/2)² = 197379906.233 mi²
The surface area of the water on Earth = 75% × The area of the Earth = 75/100 × 197379906.233 = 148034929.675 mi² ≈ 1.480 × 10⁸ mi²
The expression 2a+3b gives the cost (in dollars) for a shirts and b pairs of pants at a garage sale. A. The cost for 1 shirt is $ and the cost for 1 pair of pants is $ . B. The total cost for 5 shirts and 5 pairs of pants is $ . Question 2 c. Is $20 enough to buy 7 shirts and 2 pairs of pants?
Answer:
Step-by-step explanation:
If 2a+3b gives the cost (in dollars) for a shirts and b pairs of pants at a garage sale
a) To get cost for 1 shirt and the cost for 1 pair of pants, we will substitute a = 1 abd b = 2 into the expression given
Cost = 2(1) + 3(2)
Cost = 2 + 6
Cost = $8
Hence cost for 1 shirt and the cost for 1 pair of pants is $8
b) For the total cost for 5 shirts and 5 pairs of pants;
a = 5 and b= 5
Cost = 2(5)+3(5)
Cost = 10 + 15
Cost = $25
Hence the total cost for 5 shirts and 5 pairs of pants is $25
c) To check whether $20 will be enough to buy 7 shirts and 2 pairs of pants, we will substitute a = 7 and b = 2 into the expression;
Cost = 2(7)+3(2)
Cost = 14 + 6
Cost = $20
Hence $20 will be enough to buy 7 shirts and 2 pairs of pants
Find the total cost of buying a product that cost $12 if it is 25% off. DO NOT PUT A $. Only numbers.
Answer:
the answer will be 9 dollars
Explanation:
The discount of 25% off means you save 0.25*12 = 3 dollars, meaning the final cost is 12-3 = 9 dollars.
Or you can think of it like this: if you save 25%, then you still pay the remaining 75%. So 0.75*12 = 9 dollars is the total cost.

Step-by-step explanation:
[tex]\frac{3}{12} =\frac{x}{28} \\28(\frac{3}{12} )=x\\x=7[/tex]
Answer:
7
Step-by-step explanation:
we first divide 12 by 3 and we get
[tex]\frac{12}{3}=\frac{4}{1}[/tex]
that means:
for 4 pints we have 1 pitchers
so 28=4*7
[tex]\frac{4}{1}*\frac{7}{7}=\frac{28}{7}[/tex]
so that means for 28 pints we have 7 pitchers
