The width of a rectangle is 6t-1.5 feet and the length is 1.5t+6 feet. Find the perimeter of the rectangle. The perimeter of the rectangle is nothing feet.
Answer:
15t+9 ft
Step-by-step explanation:
Given data
Width= 6t-1.5 ft
Length= 1.5t+6 ft
Required
The perimeter
The expression for perimeter is
P= 2L+2W
P= 2(1.5t+6)+ 2(6t-1.5)
open bracket
P= 3t+12+ 12t-3
collect like terms
P= 3t+12t+12-3
P= 15t+9 ft
Hence the perimeter is 15t+9 ft

Max purchased a box of green tea mints. The nutrition label on the box stated that a serving of three mints contains a total of 10 calories. Write an equation that represents C(x). Where C(x) represents the number of calories in 'x' mints. A full box of mints contains 180 calories. Determine the total number of mints in the box.
I WILL GIVE BRANLIEST PLEASE JUST ANSWER BRUV
Answer: equation is
c(x)=(10/3)x
54 mints per box
Step-by-step explanation: ok so 3 mints=10 calories
if you input 3 for number of mints, ou get 10 for caloires
10=k3
divide both sides by 3
10/3=k
therfor
C(x)=(10/3)x
full box =180 caloies
therefor
full=180=(10/3)x
multiplyboth sides by 3/10 to clear fraction (since 10/3 times 3/10=30/30=1)
540/10=x
54=x

please help shawty baes
find the volume of the composite solid
Answer:
156
Step-by-step explanation:
Volume Rectangular Prism Formula
V = L * W * H
Givens
L = 6
W = 6
H = 3
Solution
V = 6 * 6 * 3
V = 108
Volume Pyramid
Formula
V = 1/3 * B * H
Givens
B = 6*6
H = 4
Solution
V = 1/3 * 6*6 * 4
V = 1/3 * 36 * 4
V = 48
Total
Total = 108 + 48 = 156
The numbers 1 to 8 are placed in a hat. What is the probability that you will pick an odd number, and without replacing the number in the hat, select the number 2?
Answer:
1 /7
Step-by-step explanation:
Sample space =. (1, 2, 3, 4, 5, 6, 7, 8)
Odd numbers = (1, 3, 5, 7)
Probability of picking an odd number = number of odd numbers / sample space
P(odd number) = 4 / 8 = 1/2
Without replacement :
P(picking a 2) :
Sample space = 8 - 1 = 2
Hence,
P(picking a 2) = 2 / 7
P(picking an odd number and the a 2) =
1/2 * 2/7 = 2 /14 = 1/7

The perimeter of a photograph is 34 inches. It is 10 inches long. How wide is it?
inches
Answer:
the width of the photo is W = 14" / 2, or 7"
Step-by-step explanation:
Recall that P = 2W + 2L. Here L = 10" and P = 34".
Thus, 2(10") + 2W = 34", or
2W = 14"
Then the width of the photo is W = 14" / 2, or 7"
What does A U B mean?
Answer:
Math:The Union of A and B is the set of all those elements which belong either to A or to B or both A and B. use the notation A U B (which is read as 'A union B') to denote the union of set A and set B.
Algebra: n(A U B) = n(A) + n(B) - n(A n B) so 20 = n(A) + 10 - 5 OR n(A) = 15.

Brainliest for first correct awnser
Answer:
Step-by-step explanation:
x²y = k, where k is a real constant.
When x = 3.5, y = 8.
=> (3.5)²(8) = k, k = 98.
When y = 8/9,
we have x²(8/9) = (98).
=> x² = 110.25
=> x = 10.5 or x = -10.5.
Since we want the negative value,
the answer is x = -10.5.

Answer:
7/50 is the correct answer
Step-by-step explanation:
First you would need to convert this to an improper fraction which it would be 0+14/100.
Then you would add 0 and 14/100 to get the same answer 14/100
After this you would factor out the 14 and 100
Finally you should get
2(7)/ 2(50)
Now you should be able to cancel out the 2 and be left with 7/50.
Hope this helps!!!

2x^2-7=-7
This is solving quadratic functions by square roots btw
Answer:
x = 0
Step-by-step explanation:
add 7 to each side to get:
2x² = 0
divide each side by 2 to get:
x² = 0
take square root of each side to get:
x = [tex]\sqrt{0}[/tex]
x = 0
Answer:
x = 0
Step-by-step explanation:
[tex] {2x}^{2} - 7 = - 7[/tex]
[tex] = {2x}^{2} = 0[/tex]
[tex] = {2x}^{2} \div 2 = 0 \div 2[/tex]
[tex] = {x}^{2} = 0 \div 2[/tex]
[tex] = {x}^{2} = 0[/tex]
[tex] = x = 0[/tex]
