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
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

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

Step-by-step explanation:
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

Sara needs 1/3 of a yard of ribbon to make a bow. She has 10 yards of ribbon. How many bows can she make?
20 bows
30 bows
40 bows
50 bows
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

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