Step-by-step explanation:

Step 1: Define Systems

y = 2x - 4

y = -x + 5

Step 2: Solve for x

Substitution

Substitute in y:                    2x - 4 = -x + 5Add x to both sides:           3x - 4 = 5Add 4 to both sides:           3x = 9Isolate x:                              x = 3

Step 3: Solve for y

Define equation:                    y = -x + 5Substitute in x:                       y = -3 + 5Add:                                        y = 2

Logan is working two summer jobs, making $18 per hour tutoring and making $10 per hour clearing tables. In a given week, he can work a maximum of 13 total hours and must earn at least $170. If xx represents the number of hours tutoring and yy represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer: he could work 7 hours tutoring and 6 hours clearing tables

Step-by-step explanation:

The system of inequalities can be used to find the number of hours Logan

can spend on each job in a week.

Response:

The system of inequalities are;

x + y ≤ 1318·x + 10·y ≥ 170

A possible solution of the system of inequality obtained from the graph is the point (5, 8)

x = 5, and y = 8Methods used to solve the inequality graphically

The amount Logan makes per hour tutoring = $18 per hour

The amount he makes clearing tables = $10 per hour

Number of hours Logan can work in a week = 13

Amount he must earn in a week = At least $170

Number of hours he spends tutoring = x

Number of hours he spends clearing tables = y

Based on the given information, we have;

x + y ≤ 1318·x + 10·y ≥ 170

Please find attached the graph of the above inequality showing the feasible region.

A possible solution obtained from the feasible region is the point of intersection of the two inequalities which is the point (5, 8), which gives;

A possible solution is x = 5, y = 8

Therefore, Logan can spend 5 hours tutoring and 8 hours clearing tables in a week to work for 13 hours and make $170.

What is the value of p?
I don’t know how to do this

Answers

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

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

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.​

Answers

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?

Answers

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.

Answers

Answer:

the answer will be 9 dollars

Answer:   9

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.
