A rectangle is 4 times as long as it is wide. The perimeter is 30 feet. Find the dimensions.
Answer:
Express your length and width as algebraic expressions:
width = x
length = 4x
Use the formula for the perimeter of a rectangle to solve for x:
perimeter = 2(length) + 2(width)
50 = 2(4x) + 2(x)
50 = 8x + 2x
50 = 10x
5 = x
The width (x) is 5 feet and the length (4x) is 20 feet.
Step-by-step explanation:
Answer: 3 by 3 by 12 by 12
Step-by-step explanation: Two sides are x feet long. The two other sides are 4 times x feet long. 4x+4x+x+x =10x
Set that equal to 30 and solve. x=3
Plug back into the original 4x's and x's to get the lengths
A ball shaped like a sphere has a radius of 1.5 feet. What is the measurement of the volume of the ball in cubic feet?
Answer:
9.42
Step-by-step explanation:
1.5 is the radius so you plug it into [tex]\pi r^{2}[/tex] to get about 7.07 than do get the volume of a sphere you multipy by (4/3). I used my phone so you may want to use a ti84 so you can reuse the answers to get it more exact. It is a rounded answer with rounds at each step.
2. How many terms are there in the expression: 3a + 6
Answer: 2
Step-by-step explanation: That expression is a binomial in any case the terms in a polynomial are separated by a plus or minus sign (+,-) so you can determine the number of terms by counting how many number or variable are being separated (ex: 3a+a-1 would have 3 terms and be a trinomial)

Answer:
E and F
Step-by-step explanation:
✔️To eliminate the variable y, we can multiply the first equation, -x + 4y = 1 by 7 and the second equation, 8x - 7y = 42 by 4. This will leave us with the variable x alone to solve for.
✔️Alternatively, we may decide to eliminate the variable x first by multiplying the first equation, -x + 4y = 1 by 8. Both equations would be equivalent, thus when we can easily eliminate the variable x leaving us with variable y to solve for.
The length of a rectangular frame is 4 inches longer than twice the width. If the perimeter is 38 inches, find the dimensions of the frame.
WILL GIVE WHOEVER ANSWERS BRAINIEST
Answer:
The width of the rectangle is 20 inches, and the length is 36 inches.
Step-by-step explanation:
2(2x-4) + 2x = 112
4x - 8 + 2x = 112
6x - 8 = 112
6x = 120
x = 20

3x + 2y = 6 for y
Answer:
Answer:
y=3
Step-by-step explanation:
you just need to do 2 divided by 6
Answer: y = -3/2x + 3
Step-by-step explanation:
3x + 2y = 6 First Isolate y by subtracting 3x from both sides
-3x -3x
2y = -3x + 6 Now divide both sides by 2
y = -3/2x + 3

At Silver Gym, membership is $25 per month, and personal training sessions are $30 each. At Fit Factor,
membership is $45 per month, and personal training sessions are $20 each. In one month, how many
personal training sessions would Sarah have to buy to make the total cost at the two gyms equal?
Answer:
2
Step-by-step explanation:
y = mx + b
y = total cost of the gym
m = cost per personal session
x = number of sessions
b = cost of one month
Silver gym:
y = 30x + 25
Fit Factor:
y = 20x + 45
Set them Equal to each other:
30x + 25 = 20x + 45 (get Xs on one side by subtracting 20x)
10x + 25 = 45 (isolate x by subtracting 25 from both sides)
10x = 20 (divide both sides by 10)
x = 2 personal training sessions to make the cost equal

Dora is thinking of a number between 500 and 600
When she divides it by a 1-digit number it has a remainder of 4
What could Dora’s number be?
9514 1404 393
Answer:
500 ÷ 8 = 62 r 4, for example
Step-by-step explanation:
In order to have a remainder of 4, the divisor must be greater than 4, so could be any of 5, 6, 7, 8, 9.
The corresponding numbers could be any of ...
504 +5n . . . 0 ≤ n ≤ 19
502 +6n . . . 0 ≤ n ≤ 16
501 +7n . . . 0 ≤ n ≤ 14
500 +8n . . . 0 ≤ n ≤ 12
508 +9n . . . 0 ≤ n ≤ 10
__
For example, with the divisor being 6, and n=13, the number could be ...
580 = 6·96 + 4

Answer:
The third one
Step-by-step explanation:
Since this is looking down on the cubes from above, I feel it is safe to assume that it is the third one.
From left to right, top to bottom:
3, 2, 2
2, 2, 1
2, 2, 1
We can see that all but 3 layers are 2 blocks high. The 3 block area is the top left corner, since it is 1 block higher than the 2 block areas, and the 1 block areas are the middle right and the bottom right areas.

Answer:
25 cm is the perimeter...........
Answer:
25 cm
Step-by-step explanation:
When you are told that any figure is regular it means all the sides have the same value.
A pentagon has 5 sides.
Each side is 5 cm.
The perimeter is the addition of all the sides.
To find it we just multiply
5*5= 25 cm

Write an equation in slope-intercept form for the line between (2,7) and (6, 19)
Answer:
y= 3x +1
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope and c is the y-intercept.
Gradient= [tex] \frac{y1 - y2}{x1 - x2} [/tex]
☆ (x1, y1) is the 1st coordinate and (x2, y2) is the 2nd coordinate
Using the formula above, slope of line
[tex] = \frac{19 - 7}{6 - 2} \\ = \frac{12}{4} \\ = 3[/tex]
Subst. m=3 into the equation:
y= 3x +c
To find the value of c, substitute a pair of coordinates.
When x= 2, y= 7,
7= 3(2) +c
7= 6 +c
c= 7 -6
c= 1
Thus, the equation of the line is y= 3x +1.
