Bob would like to create a triangle that is seven less than twice the perimeter of the triable below. Give an expression of the perimeter of the new triangle.
Answer:
[tex] 14y + 9 [/tex]
Step-by-step explanation:
Perimeter of the triangle = [tex] (y + 9) + 2y + (4y - 1) [/tex]
[tex] y + 9 + 2y + 4y - 1 [/tex]
Combine like terms
[tex] y + 2y + 4y + 9 - 1 [/tex]
[tex] Perimeter = 7y + 8 [/tex]
If Bob creates a new triangle whose perimeter is 7 less than twice the perimeter of the given triangle, the expression for the perimeter of the new triangle would be:
Twice of the perimeter = 2(7y + 8)
7 less than twice the perimeter = 2(7y + 8) - 7
Simplify the expression
New perimeter = [tex] 2(7y + 8) - 7 [/tex]
= [tex] 2*7y + 2*8 - 7 [/tex] (distributing 2)
[tex] = 14y + 16 - 7 [/tex]
New perimeter [tex] = 14y + 9 [/tex]

What is the the simplified form of the following expression? 5 ( t - 1 ) (please see picture below to find your answer choices)
Answer:
d is correct
Step-by-step explanation:
tara bakes 225 cookies in 5 hours, and she uses 8 pounds of sugar. she divide 225 by 5 to grt a rate of 45. which of the following correspond to this rate
Options :
A cookies per pound
B. O pounds per hour
c. cookies per hour
D. hours per cookie
Answer: C.) Cookies per hour
Step-by-step explanation:
Given the following :
Number of cookies baked = 225 cookies
Total time taken = 5 hours
Amount of sugar used = 8 pounds
Tara divides 225 by 5; 225 / 5 = 45
Rate gives the amount or number of times something occurs within a given period, Hence
The rate obtained by Tara corresponds to the ratio of ; (Total cookies baked / total time taken) = (225 / 5), this translates to the amount or number of cookies baked within an hour.
Answer:
I choose C for mine and was correct :)

Find the equation of the exponential function represented by the table below:
x y
0 2
1 6
2 18
3 54
Answer:
y = 2[tex](3)^{x}[/tex]
Step-by-step explanation:
For the exponential function in the form
y = a[tex]b^{x}[/tex]
Use ordered pairs from the table to find a and b
Using (0, 2 ), then
2 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ) , thus
a = 2, so
y = 2[tex]b^{x}[/tex]
Using (1, 6 ) , then
6 = 2b ( divide both sides by 2 )
b = 3
Thus the exponential function is
y = 2[tex](3)^{x}[/tex]

A girl wanted to buy 9 apples but she needed 7 more dollars. So instead bought 3 apples and had $11 leftover. How much money does she have?
Answer:
19
Step-by-step explanation:
Answer:
She started with 20 dollars.
Step-by-step explanation:
each apple is 3 dollars because if she bought 3 apples that would be 9 dollars, and 9+11= 20. And if she was trying to buy 9 apples that would equal 27 dollars which means she would need 7 dollars more.

Answer:
the median is 2
Step-by-step explanation:
Answer:
Third Option.
Step-by-step explanation:
First Option:
The mode means the option that is selected the most.
There are 7 votes for 1 state, hence 1 is the mode as it is voted the most.
FALSE.
Second Option:
The median means the middle when arranged in numerical order.
Arranging them:
[tex]1,1,1,1,1,1,1,2,2,2,2,2,3,3,5[/tex]
If you look for the middle term, it is 2 which is the median.
Therefore, the median is not 3.
FALSE.
Third Option:
Four out of 5 students lived in only 1 or 2 states.
[tex]\frac{4}{5} *15=12[/tex]
12 students live in only 1 or 2 states.
If we count the number of people living in 1 or 2 states, we get 12.
TRUE.
Fourth Option:
There is no data for 7 states.
FALSE.

A triangle has side lengths of (5.8k+3.3m)(5.8k+3.3m) centimeters, (8.4k-2.4n)(8.4k−2.4n) centimeters, and (7.9n-4.4m)(7.9n−4.4m) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
(14.2k - 1.1m + 5.5n) cm
Step-by-step explanation:
Perimeter of a triangle = side A + side B + side C
Side A = (5.8k+3.3m)cm
Side B = (8.4k-2.4n)cm
Side C = (7.9n-4.4m)cm
Perimeter of a triangle = side A + side B + side C
= (5.8k+3.3m) + (8.4k-2.4n) + (7.9n-4.4m)
= 5.8k + 3.3m + 8.4k - 2.4n + 7.9n - 4.4m
Collect like terms
= 5.8k + 8.4k + 3.3m - 4.4m - 2.4n + 7.9n
= (14.2k - 1.1m + 5.5n) cm
Therefore, the perimeter of the triangle = (14.2k - 1.1m + 5.5n) cm

An ice cream factory makes 270 quarts of ice cream in 2 hours. How many quarts could be made in 48 hours. What was the rate per day
Answer:
6480 quarts in 48 hours
3240 quarts in a day(24 hours)
Step-by-step explanation:
2*24 is 48, so then 270*24=6480
and then half of 48 hours is a day so just half of 6480
Answer:
6480 quarts in 48 hours
3240 quarts per day
270*24= 6480
6480/2= 3240
