-2r = 28
divide by -2
r = -14
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

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.
In ΔNOP, m ∠ N = ( 9 x + 8 ) ∘ m∠N=(9x+8) ∘ , m ∠ O = ( 4 x + 13 ) ∘ m∠O=(4x+13) ∘ , and m ∠ P = ( 2 x − 6 ) ∘ m∠P=(2x−6) ∘ . Find m ∠ N . m∠N.

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]
Which graph has a rate of change of zero? On a coordinate plane, a vertical line is at x = 3. On a coordinate plane, a horizontal line is at y = 3. On a coordinate plane, a line with positive slope goes through (0, 0) and (1, 3). On a coordinate plane, a line with negative slope goes through (negative 1, 3) and (0, 0).
Answer:
horizontal line y = 3
Step-by-step explanation:
The slope of a line gives the measure of its rate of change.
The horizontal line with equation y = 3 is parallel to the x- axis and has a slope of zero.
Thus y = 3 has a rate of change of zero
Answer:
Horizontal line y = 3.

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 :)

whats the answer to -3/4=x-6
Answer:
x = 21/4
x = 5 1/4
Step-by-step explanation:
Hi there !
- 3/4 = x - 6
- 3 = 4(x - 6)
- 3 = 4x - 24
4x = 24 - 3
4x = 21
x = 21/4
x = 5 1/4
Good luck !

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.
