morpeh [17]

Answer:

16 slices

Step-by-step explanation:

Given :

Number of pizzas ordered = 4

Number of slices per pizza = 4

If 4 pizzas are each sliced into 4 parts ; the we have :

Pizza 1 = 4 slices

Pizza 2 = 4 slices

Pizza 3 = 4 slices

Pizza 4 = 4 slices

Total slices = (4 +4 +4 +4) = 16 slices

A log splitter can split 6/5 cords of wood in 4/5 of an hour. Complete the unit rate by setting up a complex fraction and simpli

Digiron [165]

Answer:

1½ cords per hour

Step-by-step explanation:

A log splitter can split 6/5 cords of wood in 4/5 of an hour.

To find a unit rate, we divide the quantity of cords of wood by the time.

This gives us the complex fraction.

$\frac{ \frac{6}{5} }{ \frac{4}{5} }$

This is the same as

$\frac{6}{5} \div \frac{4}{5}$

To divide two fractions, we multiply by the reciprocal of the second fraction.

$\frac{6}{5} \times \frac{5}{4}$

$\frac{3}{1} \times \frac{1}{2}$

This simplifies to:

$\frac{3}{2} = 1 \frac{1}{2}$

The unit rate is 1.5 cords per hour

14.Find the value of <A in the following figure.<br>

OLga [1]

Given:

The figure of triangle ABC.

To find:

The measure of angle A.

Solution:

From the given figure, we get

$\angle ABC+120^\circ=180^\circ$ (Linear pair)

$\angle ABC=180^\circ-120^\circ$

$\angle ABC=60^\circ$

According to the exterior angle theorem, the exterior angle of a triangle is equal to the sum of two opposite interior angles.

$\angle A+\angle ABC=105^\circ$ (Exterior angle theorem)

$\angle A+60^\circ=105^\circ$

$\angle A=105^\circ-60^\circ$

$\angle A=45^\circ$

Therefore, the measure of angle A is 45 degrees.
