Can someone explain the steps to solve number two?

1 answer:

7 0

Ok so first you would create a proportion.
8/x=4/1. Next you cross multiply and divide,
1 • 8÷4=x. Ratios are fractions with the first number being the numerator and the second being the denominator. If you think of it this way, you just find an equivalent fraction. Your answer would be 8:2 because in your proportion x=2.

Answer:

9 cm

Step-by-step explanation:

The volume of a square based pyramid is given as :

V = 1/3a²h

Where ; a = base edge ; h = Height

Volume, V = 48 cm³ ; a = 4cm

48 = 1/3 * 4² * h

48 = 1/3 * 16h

48 * 3 = 16h

144 = 16h

h = 144 / 16

h = 9 cm

Height = 9cm

A cylinder’s volume can be calculated by the formula V=pir^2h , where V stands for volume, R for the base radius and H for the c

Answer:

Step-by-step explanation:

Formula

V pi * r^2 * h

Givens

r = 3 m

h = 6 m

pi = 3.14 when used.

Solution

V = pi r^2 * h

V = pi * 3^2 * 6

V = 9 * 6 * pi

V = 54 * pi Volume in terms of pi

V = 54*3.14 Volume using a value for pi

V = 169.56 to the hundred's place.

Two points, A and B, are on opposite sides of a building. A surveyor chooses a third point, C, 60 yd from B and 105 yd from A, w

Virty [35]

In the given question it is given that , AC = 105 yd, BC = 60 yd and angle ACB= 69.3 degree.

We have to find the distance of AB, and for that we use law of cosine, which is

$(AB)^2 = (AC)^2 +(BC)^2-2(AC)(BC) cos \theta$

Substituting the values of AC, BC and theta, we will get

$(AB)^2 = 105^2 +60^2 -2(105)(60) cos 69.3$

$(AB)^2 = 10171.217$

$AB= 101 yard$
