Answer:
Step-by-step explanation:
Im pretty sure this 3d object is a prism but the formula for it should be V=B(base area) x h(height) so V= 120 x 10 = 1200in^3
0.80m
0.50c
1.40B
0.50(8)+0.80(16)
1.40(5)-12.8(3)
31.04 should be your answer, sorry if I'm wrong!
Answer:
Step-by-step explanation:
a) You want the ratio ...
(Salena's earnings)/(Drew's earnings)
It is convenient to fill in the numbers from the first line of the table:
(Salena's earnings)/(Drew's earnings) = 31/33
b) Salena's earnings in 4 days will be double her earnings in 2 days.
4 days' earnings = 2×$62 = $124
c) Salena's earnings in 30 days will be 10 times her earnings in 3 days.
30 days' earnings = 10×$93 = $930
_____
<em>Alternate solution</em>
You can go to the trouble to write an equation for Salena's earnings (s) in terms of the number of days (d). That would be ...
s = 31d
Then you can fill in d=4 or d=30 to find her earnings for 4 or 30 days. For this problem, enough information is given in the table that shortcuts can be used, simplifying the problem immensely.
Total length of the road = 6 3/4 miles.
Each markers are spaced at a distance = 1/8 of a mile.
Number of markers could be represented by following division problem:
Total length of the road ÷ each marker space =
<h3>a) 6 3/4 ÷ 1/8.</h3>
b) In order to solve it, we need to convert that fraction into improper fraction:
6 3/4 = 27/4
6 3/4 ÷ 1/8 = 27/4 ÷ 1/8
We need to convert division sign into multiplication sign and flip the second fraction.
27/4 × 8/1
On simplifying, we get
27 × 2 = 54.
<h3>c) There would be total number of 54 markers of lengths (1/8) of a mile.</h3>
