A contractor bought 12.6 ft2 of sheet metal. He has used 3.7 ft2 so far and has $160.20 worth of sheet metal remaining. The equation 12.6x−3.7x=160.2 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answer:$18 per square foot
Step-by-step explanation:
12.6x-3.7x=160.2
8.9x=160.2
x=18
$18 per square foot

Answer:
the answer would be B: 4x=3y
Step-by-step explanation:
this is perimeter which means that you add the side lengths all together.
5x-3y+x+4y-2x+2y
then you just add the like terms
Answer:
b) 4x + 3y
Step-by-step explanation:
add all equations (perimeter = side + side + side)
P= 5x-3y + x+4y -2x+2y
combine like terms
5x + x - 2x = 4x and -3y + 4y + 2y = 3y
P = 4x + 3y
4/28 - [10 + (3 + 1) x 2]]
Answer:
[tex]\frac{4}{28}-\left(10+\left(3+1\right)x\cdot \:2\right)=-8x-\frac{69}{7}[/tex]
Solving systems by substituting
Explanation:
4x+3y=37
y=x-4
4x+3(x-4)=37
4x+3x-12=37
add 12 to both sides
7x=49
x=7
Now you use plug in x
4(7)+3y=37
28+3y=37
subtract 28 to both sides
3y=9
y=3
answer: x=7 and y=3
Four lab rats stage a daring escape in broad daylight, eventually establishing a colony behind the laboratory's parking garage. After one month, the population of the colony has risen to eight rats. After two months, the population is sixteen; after three months, thirty-two, and so on. If the pattern continues, how many months will it take for the colony population to reach 1,024 rats?
Answer: 9 months
Step-by-step explanation:
It's a pattern of multiplying by 2.
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
128 x 2 = 256
256 x 2 = 512
512 x 2 = 1,024

In a neighborhood of 72 families. 18 families on one or more cats. Write the number of families who own one or more cat as a fraction. Then write the fraction as a decimal.
Answer:
0.25
Step-by-step explanation:
The fraction is 18/72. The decimal is different. If you divide 72 by 18, you get 4. That tells you how it is in a quarter, aka four pieces. Divide 100 by 4, you get 25. That’s why the answer is 0.25

Santa Claus has been experiencing some recent back pain and is unable to carry large bags of toys over his shoulders. As a result, he has decided to use FedEx to deliver many of his gifts this year. FedEx charges a flat rate of $2.50 plus $0.85 per pound. If the cost of sending gifts to the Jones's was $28.85, how much did their gifts weigh?
Answer:
31 pounds
Step-by-step explanation:
From the information given, you can write the following formula to calculate the total cost of sending gifts:
Total cost of sending gifts=2.50+0.85x, where x is the weight of the gifts in pounds
Also, you know that the total cost of sending gifts is $28.85 and you can replace this value and solve for x:
28.85=2.50+0.85x
28.85-2.50=0.85x
26.35=0.85x
x=26.35/0.85
x=31
According to this, the answer is that the gifts weighed 31 pounds.
A company manufactures two products. A and B on two machines, I and II. It has been determined that the company will realize a profit of $3/unit of product A and $5/unit of product B. To manufacture a unit of product A requires 11 min on machine I and 7 min on machine II. To manufacture a unit of product B requires 19 min on machine I and 11 min on machine II. There are 5 hr of machine time available on machine 1 and 3 hr of machine time available on machine II in each work shift. How many units of each product should be produced in each shift to maximize the companies profit?
Answer:
product A on machine 1 would make 27 units (rounded down) 81 dollars profit.
product A on machine 2 would make 25 units (rounded down) 75 dollars profit.
product b on machine 1 would make 15 units (rounded down) 75 dollars profit.
product b on machine 2 would make 16 units (rounded down) 80 dollars profit.
Step-by-step explanation:
a1 refers to product a on machine 1
a2 refers to product a on machine 2
same rule applies for product b 1 and 2

find the slope of the line through each pair of points
(-3,9), (0,3)
Answer:
-2
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 3-9)/(0- -3)
= (3-9)/(0+3)
= -6/3
= -2
Five years ago, Charlie was twice older than Priya. What are their ages now if in 3 years the sum of their ages will be 76?
I need both ages thx
present age of charlie is 45 years
present age of priya is 25 years
Step-by-step explanation:
Let start from five years ago
Let at that age of Priya was x years
given that
Charlie was twice older than Priya
age of Charlie = 2x
_____________________________________________
present age of charlie = age 5 years ago + 5 years = 2x + 5
present age of priya = age of priya 5 years ago + 5 years x + 5 = x + 5
_________________________________________________
age of charlie 3 years from now = present age of charlie + 3 years
age of charlie 3 years from now =2x + 5 + 3 = 2x + 8
age of priya 3 years from now = present age of priya + 3 years
age of priya 3 years from now =x + 5 + 3 = x + 8
Given that
in 3 years the sum of their ages will be 76
thus
sum of their ages in 3 years from now = x + 8 + 2x + 8 = 76
=> 3x + 16 = 76
=> 3x = 76-16 = 60
=> x = 60/3 = 20
Thus,
present age of charlie = 2x + 5 = 2*20 + 5 = 45 years
present age of priya = x + 5 = 20 + 5 = 25 years
will mark the brainiest.

Answer:
The difference quotient of f is 8. Option C
Explanation:
Difference Quotient
Given a function f(x), the difference quotient is defined as
[tex]\displaystyle d=\frac{f(h+h)-f(x)}{h},\ h\neq 0[/tex]
The function provided in the question is
[tex]f(x)=8x+1[/tex]
Find f(x+h) by substituting x by x+h:
[tex]f(x+h)=8(x+h)+1[/tex]
[tex]f(x+h)=8x+8h+1[/tex]
Now compute:
[tex]\displaystyle d=\frac{8x+8h+1-(8x+1)}{h}[/tex]
Operating:
[tex]\displaystyle d=\frac{8x+8h+1-8x-1}{h}[/tex]
Simplifying:
[tex]\displaystyle d=\frac{8h}{h}[/tex]
d=8
A. Incorrect.
This choice is different from the answer.
B. Incorrect.
This choice is different from the answer.
C. Is correct
The difference quotient is 8 as explained above.
D. Incorrect.
This choice is different from the answer.
