Answer:
l = 16 cm
Step-by-step explanation:
Let's set the width of the rectangle as "w" and the length of the rectangle as "w/2 + 9".
The perimeter of a rectangle is calculated by adding up the value of all of its side lengths. Therefore, we can find the perimeter using 2l + 2w = P.
We can substitute 60 for P and w/2 + 9 for l.
2(w/2 + 9) + 2w = 602w/2 + 18 + 2w = 60 w + 18 + 2w = 603w + 18 = 603w = 42w = 14Substitute w = 14 into the equation for length l.
l = w/2 + 9 l = 14/2 + 9 l = 16The length of the rectangle is 16 cm.
PLZ HELP I WILL MARK BRAINLIEST A rectangular prism has a base that is 5 cm by 7 cm and a height of 12 cm. If all dimensions are doubled, what happens to the volume? When the dimensions are doubled, the volume is twice the original volume. When the dimensions are doubled, the volume is three times the original volume. When the dimensions are doubled, the volume is four times the original volume. When the dimensions are doubled, the volume is eight times the original volume.
Answer:
When the dimensions are doubled, the volume is eight times the original volume.
Step-by-step explanation:
difference in volume = volume of prism with dimensions doubled / original volume of prism
Volume of a prism = length x width x height
original volume of prism = 7 x 5 x 12 = 420
doubled dimensions of prism = (7x2) x (5x2) x (12 x 2)
volume = 14 x 10 x 24 = 3360
3360 / 420 = 8
Answer: D When the dimensions are doubled the volume is eight times the original volume

There are 45 rows of tomato plants in the hydroponics farm at O'Brien's Farms Each row has 14 plants. 2/3 of the plants have sprouted. How many sprouted plants does O'Brien's have?
Answer: 420 sprouted plants
Step-by-step explanation:
First find the total number of tomato plants in the farm.
= Number of rows * No. of plants per row
= 45 * 14
= 630 plants
2/3 of them have sprouted so the number of sprouted plants is:
= 2/3 * 630
= 420 sprouted plants

Answer:
The angle marked E is 120 degrees
Step-by-step explanation:
Here, we want to get the value of the angle marked E
when two triangles are similar/congruent, we have equal angle measures
Using the markings, we can deduce the following relationships;
4y -28 = 83 + y
4y-y = 83 + 28
3y = 111
y = 111/3
y = 37
So, we have;
4y-28 as
4(37) - 28
= 120

Answer:
D. 150
Step-by-step explanation:
X = W/5
X + W = 180
*If X = 30, and W = 150:
30 = 150/5

A
$66.33
B
$65.71
С
$62.28
D
$56.21
Answer:
B
Step-by-step explanation:
52.78×6.5%=3.43
52.78×18%=9.50
52.78+3.43+9.50=65.71

I have no idea what to do! Help
Answer:
X= 1.8
Step-by-step explanation:
If I’m not mistaken then this is how to work it out. X^2 + 4x -9 =0. X^2 + 4x would be 5x. 5x - 9 = 0. +9 on both sides. 5x=9. Divide by 5 on each side. X= 1.8

Represent 0.533 (only the last 3 is bar number) into a rational number
Answer:
[tex]\frac{8}{15}[/tex]
Step-by-step explanation:
We require 2 equations with the repeating 3 placed after the decimal point.
let x = 0.5333.. ( multiply both sides by 10 and 100 )
10x = 5.333... → (1)
100x = 53.333... → (2)
Subtract (1) from (2) tus eliminating the repeating 3
90x = 48 ( divide both sides by 90 )
x = [tex]\frac{48}{90}[/tex] = [tex]\frac{8}{15}[/tex]
Answer:
IT IS 8/15
Step-by-step explanation: Divide and multiply the fraction from 100 to tens
Solve for b pls. Due by 2:45.....
Answer:
b = 12
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
b² + 5² = 13²
b² + 25 = 169 ( subtract 25 from both sides )
b² = 144 ( take the square root of both sides )
b = [tex]\sqrt{144}[/tex] = 12
help me with this math question gr 8 math please
Answer:
C = 112, A = 150, D = 30, B = 38
Step-by-step explanation:
I solved C first using:
30+38+c = 180 (angles along a straight line should add up to 180 since a whole circle is 360)
-
I solved A by looking across from C.
Angles on opposite sides should mirror each other but A includes 38* + C
Just by doing 112 + 38 you get 150.
-
I solved D by looking at 30*, alternative interior angles are the same so D is 30*.
-
I solved B by taking C (112) and D (30) and adding them together and subtracting from 180.
Interior angles of a triangle should all add up to 180,
112 + 30 + B = 180
From this I got that B was 38.
Alternatively you can find this out by looking at the 38 degrees, corresponding congruent angles are always the same.
I suggest reviewing this angles sheet if you're ever stuck in the future.
Answer:
C = 112, A = 150, D = 30, B = 38

Write an equation in slope-intercept form of the line that passes through the given points.
Answer:
y = 2
Step-by-step explanation:
Since the y- coordinates of the ordered pairs are all 2
This indicates the line is horizontal with equation y = c
where c is the value of the y- coordinates the line passes through, then
y = 2 ← equation of line
