Answer:
A) D + Q = 50
B) .10D + .25Q = 7.10
We multiply A) by -.10
A) -.10D - .10Q = -5 then adding this to B)
B) .10D + .25Q = 7.10
.15Q = 2.10
Quarters = 14 = 3.50
Dimes = 36 = 3.60
Step-by-step explanation:
Answer:
<em><u>16:</u></em>
4*4
8*2
1*16
Step-by-step explanation:
"Factors" are the numbers you multiply to get another number. For instance, factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4.
18hrs because its a scale factor of 1.5
10-D
12- A
first of all find the area of the whole rectangular:
3+3=6
3*6=18
then small one
3*3= 9
18-9 =9
Answer:
Step-by-step explanation:
Considering that The Student Council expects to 150 students for a dance, and spends $10 per student.
If the expectancy is that the number of students increases by 8%
Then since the growth is 8%
we can write the the Predicted Number of Students as a Geometric Sequence,
A.
Therefore,
B) If we spend $10 per student on the 1st year, but the Council wants to reduce the expenditure 4% yearly. Since we want to reduce 4% we must multiply by 96%.
Therefore we can write:
C)
The total expenditure for food must be reduced, by 4%. As long as the public goes increasing by 8% yearly this
So,
