Answer:
The supposition is incorrect.
Step-by-step explanation:
The growth rate of a child is not constant, so height versus time does not look like a straight line. Nothing is wrong with the prediction made using the false assumption. You can conclude anything you like when you start with a false premise.
Answer:
The surface area is 91
Step-by-step explanation:
3*4=12
12/2=6
6*2=12
7*5=30
4*7=28
3*7=21
12+30+28+21=91
The equations that are on the left are caculations triangle calcuations. The equations on the right are the ones that equal each of the 2d shapes in the prism and if u add them all up you get your surface area.

Answer:
13a) $3.40
13b) 0.85X
13c) $25.88
Step-by-step explanation:
13a) When there is a 15% discount, we can say that we are only paying 85% of the original price because out of 100%, 15% is taken away. 85% in decimals is 85/100 = 0.85.
$4 x 0.85 is the discounted price, which is $3.40
13b) In 13a, the price was 4. Now, the price is X. Hence we plug in (substitute) X in for 4, giving us X x 0.85, which we can write as 0.85X
13c) 85% of the cake is $22. To find 100% of the price, we can find 1% of the original price and then multiply that by 100, which gives us 100% of the price.
We know 85% of the original price. Therefore, dividng the price by 85 will give us 1% of the price. 1% = $22/85
Finally, to calculate 100%, we multiply by 100.
22/88 x 100 = 440/17 which is 25.882 in decimals, which we round to 2 decimal places (because it is currency) = $25.88
Answer:
m = 5
Step-by-step explanation:
Remark
This is a proportion question. A proportion is 2 equal ratios. There are 4 parts to a proportion. If 3 are known, the 4th can be found.
Formula
AB/AC = RQ/QS
Givens
AB = m
AC = 2
RQ = 10
QS = 4
Solution
m/2 = 10/4 Multiply both sides by 2
2m/2 = 2*10/4 Combine
m = 20/4
m = 5
Answer m = 5
