Answer:

$\frac{9}{5}$

Step-by-step explanation:

$\frac{4}{9}$ × $\frac{45}{36}$

= $\frac{4}{9}$ × $\frac{5}{4}$ ( cancel 4 on numerator/ denominator )

$\frac{5}{9}$

Given a number n then its reciprocal is $\frac{1}{n}$

Then the reciprocal of $\frac{5}{9}$ is

$\frac{1}{\frac{5}{9} }$ = $\frac{9}{5}$

Find the area of a parallelogram with the given vertices. P(-2, -5), Q(9, -5), R(1, 5), S(12, 5)

valentina_108 [34]

Answer:

The area of the parallelogram is 55 square unit.

Step-by-step explanation:

The area of a parallelogram is

$A=\frac{1}{2}\times base\times height$

It is given that the vertices of the parallelogram are P(-2, -5), Q(9, -5), R(1, 5), S(12, 5).

Plot these points on a coordinate plane, and draw a perpendicular on PQ from the point R.

From the graph is clear that length of PQ is 11 and the height of the parallelogram is 10. So, the area of a parallelogram is

$A=\frac{1}{2}\times 11\times 10$

$A=55$

Therefore the area of the parallelogram is 55 square unit.

an architect is presenting a scale model of a building she's designed to the planning committee of college the scale of the mode

Naddik [55]

The tall of the actual building will be 216 feet

Step-by-step explanation:

An architect is presenting a scale model of a building she's designed

to the planning committee of college

1. The scale of the model is 1 inch = 18 feet

2. The tallest wall in the model is 12 inches

3. We need to know how tall the actual building will be

Let us used the ratio method

∵ The scale of the model is 1 inch represents 18 feet

∵ The tallest wall in the model is 12 inch

→ Model(in) : Actual(ft)

→ 1 : 18

→ 12 : h

- By using cross multiplication

∴ 1 × h = 12 × 18

∴ h = 216 feet

∴ The actual height is 216 feet

The tall of the actual building will be 216 feet
