blagie [28]

Answer:

12 3/8

Step-by-step explanation:

A = 2 3/4 x 4 1/2

best way is to change mixed numbers to fractions and multiply and then go back to a mixed number.

11/4 x 9/2 = 99/8 = 12 3/8

7. If 1 || m and n || q, identify any of the following<br> angles congruent to 6
s344n2d4d5 [400]

The angle congruent to ∠6 are ∠8, ∠3, ∠9 and ∠14

<h3>How to find congruent angles?</h3>

When parallel lines are cut by a transversal, angle relationships are formed. They include corresponding , alternate and many more.

L║m

n ║ q

Therefore, the angles congruent to ∠6 by alternate or corresponding relationship are as follows:

∠6≅∠8≅∠3≅∠9≅∠14

A rectangular tank 60 cm long and 50 cm wide is /5 full of water. When 24 liters of water are added, the water level rises to th
bija089 [108]

Answer:

The tank is 10cm high

Step-by-step explanation:

Given

L=60cm -- length

W=60cm -- width

x = \frac{1}{5} --- water lever

Addition = 24L

Required

The height of the tank

Let y represents the remaining fraction before water is added.

So:

y + x = 1

Make y the subject

y = 1 - x

y = 1 - \frac{1}{5}

Solve

y = \frac{5 - 1}{5}

y = \frac{4}{5}

Represent the volume of the tank with v

So:

y * v = 24L

Make v the subject

v = \frac{24L}{y}

Substitute: y = \frac{4}{5}

v = \frac{24L}{4/5}

v = 30L

Represent the height of the tank with h;

So, the volume of the tank is:

v = lwh

Make h the subject

h = \frac{v}{lw}

Substitute values for v, l and w

h = \frac{30L}{60cm * 50cm}

Convert 30L to cm^3

h = \frac{30*1000cm^3}{60cm * 50cm}

h = \frac{30000cm^3}{3000cm^2}

h = 10cm
