Answer:

x=30

Step-by-step explanation:

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

x=30

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

Answer:

C.) 35

Step-by-step explanation:

Supplementary angles equal 180, therefore, the opposite side of both the angles 90 and 125, must be 180 minus that value.

180-125=55

180-90=90

Now we know that the two inside angles equal 55 and 90. Together, that's 145.

Since all the angles within a triangle equal 180, we subtract the two other angles to find p.

180-145=35

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.

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

Answer:

Step 1: Subtract x from both sides.

x+3−3=−4−3

x=−7

Answer:

x=−7

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].

Answer:

30 Bows

Step-by-step explanation:

Every yard is 3 feet, and each bow calls for 1/3 of a yard, so a foot per bow.

So you can make 10 yards, 30 feet by multiplying by 3, and then its pretty straight forward from there. 30 / 1 = 30 Bows

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
