C. 135
Corresponding parts of congruent figures are the same
Answer:
A: 7
B: 8
C: 6
Step-by-step explanation:
You have to try to find the the same greatest factor of both of the numbers.
Since both of the numbers are divisible by 7 the number of groups equals 7.
So you divide the number of girls, which is 56, by 7, the number of girls in each group is 8.
Then you divide the number of boys, which is 42, by 7, the number of boys in each group is 6.
Coffee = $12
Tea = $8
Total cost = $2600
Total Case = 250
Assumed all 250 cases are Tea
250 x 8 = 2000
Difference in amount
2600 - 2000 = 600 (so $600 was from the coffee)
Difference between the price of coffee and tea
12 - 8 = $4
Number of cases of coffee
600 ÷ 4 = 150
Number of cases of tea
250 - 150 = 100
150 cases of coffee were ordered
Answer:
103.6726
Step-by-step explanation:
C=2πr
radius is half of diameter, so its 16.5
2* 3.14*16.5
C=103.62
103.6726 to be exact.
Answer:
The slope is -7/4
Step-by-step explanation:
∵ 7x + 4y = 10
∵ y = mx + c ⇒ where m is the slope of the line
∴ Re-arrange the equation
∴ 4y = 10 - 7x ⇒ ÷4
∴ y = 10/4 - (7/4) x
∴ y = 5/2 - (7/4) x
∴ The slope is -7/4
