It 7 hours and 5 minutes to complete the race because it would be 8 times 50 which equals 400 and 400 plus 250 which equals 650 and 650 divided by 60 is 7.5 which is 7 hours and 5 minutes I believe so 7.5 is the answer.............

10. If ABCD is a kite, DB=48 in. and CE=7 in. find DC. *
Dmitry_Shevchenko [17]

Answer:

25 in.

Step-by-step explanation:

DEC is a right triangle. <DEC is a right angle.

(DE)² + (EC)² = (DC)²

DE = ½DB = ½(48 in.) = 24 in.

(24 in.)² + (7 in.)² = (DC)²

576 in.² + 49 in.² = (DC)²

(DC)² = 625 in.²

DC = 25 in.

Answer:

D

Step-by-step explanation:

Ben is buying 30 juice boxes. Since each pack has 3 juice boxes, we can make it (30 / 3) so far. 30 / 3 is how many packs Ben buys. Now, since each pack is $1.25, we have to multiply 30 / 3 by 1.25.

Therefore, the answer is c = (30 / 3) * 1.25

zmey [24]

Answer:

3 pencils

Step-by-step explanation:

We are given Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.

Number of pencils=72

Number of calculators=24

If Zayed creates the greatest number of identical packages

Then , we find GCF of 72 and 24

72=2\times 2\times 2\times 3\times 3

24=2\times 2\times 2\times 3

GCF=2\times 2\times 2\times 3

Hence, Zayed creates 24 packages.

Number of pencils in each package=\frac{72}{24}=3

Hence, 3 pencils and one calculator will be in each package .
