Answer: 44

Step-by-step explanation:

1/5 of the slab are grey implies that 4/5 are yellow.

The ratio of grey to yellow is thus given as :

1/5 : 4/5

which is 1 : 4

Therefore , the ratio of grey to yellow is 1: 4

The total ratio = 1 + 4 = 5

To calculate the number of yellow , we use the formula

number of yellow = $\frac{ratio of yellow}{total ratio}$ X total number of slabs , that is

number of yellow = $\frac{4}{5}$ X 55

number of yellow slab = 44

dybincka [34]

Answer:

.1273 mi = 627.2 feet

c = 2 $\pi$ r

.4 = 2 $\pi$ r

r = $\frac{.4}{2\pi }$

r = $\frac{.2}{\pi }$

d = $\frac{.4}{\pi }$

d = .1273 mi = 627.2 feet

Sam cut a flat wooden board into fourths. He used three of the pieces as backgrounds for posters. He used equal pieces of the le

grandymaker [24]

To answer this question you would start with 1 whole piece and break it into 4 equal pieces. Each piece would be 1/4 of the original.

If you used 3 of these, you are left with 1/4.

Out of the 1/4 leftover, you create 5 equal-sized pieces.

1/4 divided by 5.
1/4 x 1/5 = 1/20 of the original board for each.

Three blocks a, b, and c and a grooved block d have dimensions a, b, c, and d as follows: a 5 1.500 6 0.001 in b 5 2.000 6 0.003

tankabanditka [31]

solution:

a) The mean value of gap w̅ is given by,

w̅= d̅ - a̅ - b̅ - c̅

w̅=06.520-0.150-2.000-3.000

w̅=0.020 in

bilateral tolerances of the gap is given by,

tw = ∑t

tw = 0.001+0.003+0.004+0.010= 0.018 in

w = 0.020 ± 0.018 in

b) if wmin =0.010 in , then

w̅ = wmin + tw

w̅ = 0.010+ 0.018=0.028 in

mean size of d is

d̅ = a̅ + b̅+ c̅+ w̅

d̅ =1.500+2.000+3.000+0.028

= 6.528 in
