Answer:
length=18cm,and width=9cm
Step-by-step explanation:
Let x = length
Then width = (1/2)x
Perimeter = 2(length) + 2(width) = 54
length + width = 27
So, x + (1/2)x = 27
(3/2)x = 27
x = 27(2/3) = 18 (1/2)x = 9
Answer: length = 18 cm and width = 9 cm
Answer:
Width:6 inches, Length:12 inches, Area(if needed):72 sqaure inches
Step-by-step explanation:
Put the width as w, we can write evering in terms of w.
Width: wLength: 2wPerimeter: w+2w+w+2w=6x=36, so w=36/6=6Area: w•2w=2(w^2)Now:
Width: 6 inchesLength: 2(6)=12 inchesPerimter: 36 inchesArea: 2(6^2)=2(36)=72 square inchesChange

the sum of four times a number and another number is 10. The difference of the two numbers is 35. What is the larger number? Also please explain how you got that answer
Answer:
The two numbers are 9 and -26.
The larger number is 9.
Step-by-step explanation:
Let the two unknown numbers be x and y.
The sum of a four times a number x and another number y is 10. Hence:
[tex]4x+y=10[/tex]
And the difference between the two numbers is 35. So:
[tex]x-y=35[/tex]
So, we have the system of equations:
[tex]\left\{ \begin{array} \ 4x+y=10 \\ x-y=35 \end{array}[/tex]
From the second equation, we can add y to both sides:
[tex]x=y+35[/tex]
Now, we can substitute this into the first equation:
[tex]4(y+35)+y=10[/tex]
Distribute:
[tex]4y+140+y=10[/tex]
Simplify:
[tex]5y+140=10[/tex]
Subtract 140 from both sides:
[tex]5y=-130[/tex]
Divide both sides by 5:
[tex]y=-26[/tex]
So, the value of y is -26 .
Then it follows that the value of x is:
[tex]x=y+35[/tex]
Substitute -26 for y:
[tex]x=-26+35=9[/tex]
So, our two numbers are 9 and -26.
The larger number is 9.
So, our answer is 9.

Write and solve an equation to find the number.
Five times the sum of a number(x) and 4 is –15.
Answer:
x = -7
Step-by-step explanation:
5 (x+4) = -15
Expand.
5x +20 = -15
Isolate the x.
5x = -15-20
Simplify.
5x = -35
Find x.
x = -35 ÷ 5
x = -7
Answer:
5(x+4)=-15
5x+20=-15
5x=-15-20
5x=-35
x=-7
Write an equation of the line that passes through the given point and has the given slope. (1,-5); slope: - 2/3 SLOPE INTERCEPT FORM
Answer:
y = [tex]-\frac{2}{3}[/tex] x - [tex]-\frac{13}{3}[/tex]
Step-by-step explanation:
Given dimensions:
Slope = [tex]-\frac{2}{3}[/tex]
Coordinates = (1, -5)
Now;
Equation of the line through the given points;
Solution:
The equation of a line is given as;
y = mx + c
x and y are the coordinates
m is the slope
c is the intercept
So;
let us find the y-intercept;
-5 = [tex]-\frac{2}{3}[/tex] x 1 + C
c = -5 + [tex]\frac{2}{3}[/tex] = [tex]-\frac{13}{3}[/tex]
The equation of the line is ;
y = [tex]-\frac{2}{3}[/tex] x - [tex]-\frac{13}{3}[/tex]

Charlie just bought 8 bags of 14 cookies each. He already had 9 cookies in a jar. How many cookies does Charlie have now?
Answer:
he has 121 cookies now
Step-by-step explanation:
8 times 14 plus 9
8 times 14 = 112 + 9 = 121
Answer:
121
Step-by-step explanation:
8 bags of 14 cookies means he bought 112 cookies. Since he already had 9, you add 9 to 112 and get 121 cookies in total.

4 rolls of paper towels for $5.00. how much is the cost per roll ?
Answer:
$1.25
Step-by-step explanation:
cuz 5 divided by 4 is 1.25
douple check - 1.25 times4 is 5!
Answer:
1.25
Step-by-step explanation:
If we divide the amount it costs for 4 rolls (5), by the amount of rolls bought (4), we get 1.25, which is the correct!
Don't do 4 divided by 5, or you would be saying 5 rolls bought for 4 bucks!

Step-by-step explanation:
8. The graph is of a function in the form p(t) = a • bt. What is the function? (2 points
9. Use this function to estimate the boa constrictor population in 2 years, 3 years, and 4 years. (6 points: 2 points for each year, including 1 point for showing your work and 1 point for the answer)
t: Time in years
P(t): Estimated snake population at time t

10. What pattern do you see in years 2, 3, and 4? How is the snake population changing every year? (2 points
11. How is the snake population changing every two years? (1 point
Making a Decision:
12. Do you think the snake population can continue to grow in this way forever? Why or why not? (2 points)
9514 1404 393
Answer:
8. p(t) = 5(2^t)
9. 20, 40, 80
10. doubles every year
11. multiplies by 4
12. no, it will soon exceed available habitat
Step-by-step explanation:
8. From the graph, a = p(0) = 5, and b = p(1)/p(0) = 10/5 = 2.
The function is ...
p(t) = 5(2^t)
__
9. You can read the values from the graph: 2 years: 20; 3 years: 40; 4 years: 80.
If you insist on evaluating the function, you have ...
p(2) = 5(2^2) = 5·4 = 20
p(3) = 5(2^3) = 5·8 = 40
p(4) = 5(2^4) = 5·16 = 80
__
10. The population doubles each year.
__
11. In 2 years, the population doubles twice, so is multiplied by 4.
__
12. No. Exponential functions don't last long in the real world. Eventually, required resources run out. In 15 years, there would be 163,840 snakes; in 20 years, there would be 5.2 million snakes; in 40 years, there would be 5.5 trillion snakes, about 44 snakes for every acre of land on earth (including polar areas).

A bakery produced two batches of bread with 80 loves in each batch. It sold 30 loves each hour. How many loves of bread were sold in 4 hours? How many loves of bread were left to sale
Answer:
-120 loves of bread were sold in 4 hours.
-40 loves of bread wereleft to sale.
Step-by-step explanation:
To determine the amount of loves of bead that were sold in 4 hours, you have to mutiply the amount of loves sold each hour for 4:
30*4=120
This means that 120 loves of bread were sold in 4 hours.
Now, to determine the amount of loves of bread left to sale, you have to find the amount of loves produced on the two batches of bread by multiplying the amount produce in each batch for 2:
80*2=160
Finally, you have to subtract the amount of loves sold in 4 hours from the amount produced in two batches:
160-120=40
According to this, 40 loves of bread were left to sale.

Which sentence best describes the function shown above ?
Answer:
A the function is even because of how similar the angles are.
If the length of the shorter diagonal AC of rhombus ABCD is 7 and measure of angle ABC = 60. Find the measure of angle BAC
Answer:
120 degrees
Step-by-step explanation:
It has to equal to 360, and so since angle B is 60 degrees, and it's the smaller angle, A and C have to be 120 degrees, and D has to be 60 degrees. Hope this helps.
solve the system of equations below by graphing both equations with a pencil and paper, what is the solution? y= -x-1 y=x+3
Answer:
(-2, 1)
Step-by-step explanation:
Well, to actually graph it, for the first line you'd have one point at (0, -1) [0 right, 1 down] , then you go down one, right one, and place a point there, down another, right another, and repeat.
For the second you'd place a point on (0, 3) [0 right, 3 up] and then go one up, one right, and place a point. One up, one right and place a point and repeat that. the point where the two lines cross would be your answer. If you don't want to do that then the answer is (-2, 1) I believe.
