A contractor buys 16 yd of nylon carpet and 22 yd of wool carpet for $1902. A second purchase, at the same prices, includes 20 yd of nylon carpet and 21 yd of wool carpet for $2033. Find the cost per yard of the wool carpet.
Answer:
$53
Step-by-step explanation:
Given that, two type of clothes nylon and wool carpet.
Let the price of one yard of nylon carpet = $[tex]x[/tex]
Let the price of one yard of wool carpet = $[tex]y[/tex]
Price for 16 yd of nylon carpet and 22 yd of wool carpet = $1902
Price for 20 yd of nylon carpet and 21 yd of wool carpet = $2033
Writing equations as per given statement:
[tex]16x+22y=1902 ...... (1)\\20x+21y=2033 ...... (2)[/tex]
Here, we have to find the value of [tex]y[/tex].
By equation (1), we get:
[tex]16x = 1902 - 22y \\\Rightarrow x = \dfrac{1}{16}(1902-22y) ..... (3)[/tex]
Putting the value from equation (3) to equation (2):
[tex]20 (\dfrac{1}{16}(1902-22y) ) + 21y =2033\\\Rightarrow 9510-110y + 84y = 8132\\\Rightarrow 26y=1378\\\Rightarrow \bold{y = 53}[/tex]
Therefore, the cost per yard for the wool carpet is $53.

Find the total surface area of the prism.
7 ft
8 ft
5 ft
5 ft
Answer:
The total surface area of triangular prism
A = 232 foot²
Step-by-step explanation:
Explanation:-
Given bases of prism 5 f t , 5 f t , 7 f t
The perimeter of the sum of the bases
P = 7 + 5 +5 = 17 f t
Lateral surface area =perimeter X height
= 1 7 × 8
= 136 f t²
Base area of the triangular prism = [tex]\frac{1}{2} h ( b_{1} + b_{2} ) = \frac{1}{2} 8 ( 5 +7) =48[/tex]
The total surface area of triangular prism
[tex]A = p h + 2 Base Area[/tex]
[tex]A = p h + 2 Base Area = 136 + 2 ( 4 8 ) = 232[/tex]
The total surface area of triangular prism
A = 232 foot²

A): 1/63; The car travels 1 mile every 63 hours.
B): 10; The car travels 1 mile every 63 hours.
C): 63/1; The car travels 63 miles every 1 hour.
D): 252; The car travels 252 miles.
The answer is C)
The car travels 63 mph(Miles Per Hours).
252/4 = 63
378/6 = 63
504/8 = 63
630/10 = 63
Hope Helps you
The rate of change of traveling of the car is 63 miles every 1 hour.
Rate of changeA
Distance = 252 miles
Time = 4 hours
Average speed = Distance / time= 252 / 4
= 63 miles per hour
B
Distance = 378 miles
Time = 6 hours
Average speed = Distance / time= 378 / 6
= 63 miles per hour
C
Distance = 504 miles
Time = 8 hours
Average speed = Distance / time=504 / 8
= 63 miles per hour
D
Distance = 630 miles
Time = 10 hours
Average speed = Distance / time= 630/10
= 63 miles per hour
Therefore, the rate of change of traveling of the car is 63 miles every 1 hour

1. How did you compute sums of dollar amounts that were not whole numbers? For example,
how did you compute the sum of $5.89 and $1.45? Use this example to explain your strategy.
Your answer
Answer:
Computing the sum of $5.89 and $1.45 we get: $7.34
Step-by-step explanation:
We need to explain, how can we compute the sum of $5.89 and $1.45?
Computing the sums of dollar amounts is same as computing the sum of simple decimal expressions. Each value will be added to its corresponding values and we will get the answer.
Computing the sum of $5.89 and $1.45
[tex]\:\:\:\:\:\$ \:\:5.89\\+\$ \:\:1.45\\------\\\:\:\:\:\:\$ \:\:7.34[/tex]
So, we will start adding from right side, 9 will be added with 5 and we get 14, 1 will be given carry and 8 will be added by 4 and add the carry we get 13, 1 will be given carry and 1 will be added by 5 and add the carry we get 7
So, Computing the sum of $5.89 and $1.45 we get: $7.34

since triangle BDF bisects each side of triangle AEC, then triangle BDF is a medial triangle and the result is the following:
all four triangles are congruent (their sides are proportional)
sides that measure 25: BA, BC, DF
sides that measure 30: CD, DE, FB
sides that measure 35: FA, FE, BD
if FA = 35 and FE = 35 then AE = 70

Question 1 (0.5 points)
Given a = 31, A = 84 degrees, and b = 20, use the Law of Sines to solve for B. Round
your answer to the nearest degree, and enter the number only. Note: The figure is
not drawn to scale.
Answer:
39.91 degrees.
Step-by-step explanation:
Formula
Sin(A)/a = Sin(B) / b
Givens
A = 84a = 31B = ?b = 20Solution
Sin(84)/31 = Sin(B)/20
20*Sin(84) / 31 = Sin(B)
Sin(B) = 0.6416
B = 39.91 degrees.
====================
This looks like it is right, but you should check. Let h be the height opposite angle A.
h/20 = sin(39.91)
h = 20*sin(39.91)
h = 12.83
31 has to be longer than that amount (which it is.) So there is one solution.
