The linear scale factor of two similar solids is given. Then the surface area and volume of the smaller figure are also given. Find the surface area and volume of the large figure.
Scale factor: 4:5
Surface area: 160
volume: 704
Surface area: ?
volume: ?
Answer:
Surface area: 250
Volume: 1375
Step-by-step explanation:
Scale factor: 4:5
This means that the dimensions of the larger figure are 5/4 of those in the smaller figure.
Surface area:
The surface area is found multiplying the square of the change(5/4) by the original surface area(160). So
[tex]S = (\frac{5}{4})^2 \times 160 = \frac{25}{16} \times 160 = 25 \times 10 = 250[/tex]
Volume:
The volume is found multiplying the cube of the change(5/4) by the original volume(704). So
[tex]S = (\frac{5}{4})^3 \times 704 = \frac{125}{64} \times 704 = 125 \times 11 = 1375[/tex]

Lauren shares money between herself, Millie
and Sana in the ratio of 3:4:5.
Millie gets £32. How much money should
Lauren and Sana have?
Answer:
the Lauren and sana have £24 and £40 respectively
Step-by-step explanation:
The computation of the money between lauren and sana have is as follows:
Given that
The ratio between herself, Millie and Sana is 3:4:5
And, Millie gets £32
The total money is
= £32 × (3 + 4 + 5) ÷ (4)
= £96
Lauren have
= £96 × 3 ÷ 12
= £24
And, Sana have
= £96 × 5 ÷ 12
= £40
Hence, the Lauren and sana have £24 and £40 respectively

The number of chair covers Diane will be able to make is 5.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Length of the fabric = 20 yards
Length of fabric needed for each chair cover = 3(2/5) yards
The number of chair covers that can be made with 20 yards.
= 20 ÷ 3(2/5)
= 20 ÷ 17/5
= 20 x 5/17
= 100/17
= 5.8
= 5
Thus,
The number of chair covers is 5.

Solve for w in the proportion 32/40 = 28/w W= ?
32 = 28
40 W
cross multiply so that 32W = (40*28)
then 32W = 1,120
now divide by 32 on both sides
32W = 1,120
32 32
so now it's only W = 1,120/32
which simply equals W = 35

A and B working together complete a work in 35 days. If A takes 60 days to complete it, how long would B alone tale to complete
a) 64 days
b) 72 days
c) 81 days
d) 84 days
plz ......I will surely follow you, if you answer with explanation.
Answer:
Efficiency (Work done per day) for :
( ˘ ³˘)/
A & B together = 1/35th
A alone = 1/60th
Thus, efficiency of B alone = Total - A’s efficiency
Step-by-step explanation:
OR Efficiency of B alone = (1/35) - (1/60) = 6/210 - 3.5/210 = 2.5/210 = 1/84th
Hence, since B completes 1/84th work daily, he would take 84 days to complete the work alone.
write the 0.216 in the form of p by q
Answer:
27/125
Step-by-step explanation:
Given the decimal value 0.216, we are to express as a fraction in the fofrm of p/q
0.216 = 216/1000
216/1000 = 2 * 108/2 * 500
216/1000 = 108/500
108/500 = 4*27/4*125
108/500 = 27/125
Hence the expression in form p by q is 27/125

Zada needs to simplify the expression below. 72 – 4 × 12 ÷ 6 Which solution for Zada’s expression is correct?
F. 408, because 72 – 4 is 68, 12 ÷ 6 is 6, and 68 × 6 is 408
G. 64, because 4 × 12 is 48, 48 ÷ 6 is 8, and 72 – 8 is 64
H. 4, because 4 × 12 is 48, 72 – 48 is 24, and 24 ÷ 6 is 4
J. 136, because 72 – 4 is 68, 68 × 12 is 816, and 816 ÷ 6 is 136
Answer:
order of operations matter here so
72 - 4 × 12 ÷ 6
start with 4 × 12 (which equals 48)
72 - 48 ÷ 6
next is 48 ÷ 6. (which equals 8)
72 - 8 = 64
so g is correct
