The top of a desk is shaped like a trapezoid. The bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk

Stolb23 [73]

Answer:

28 centimeters.

Step-by-step explanation:

Let w be width of desk.

We have been given that the bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk is 791 square centimeters long.

Since the area of trapezoid is half the sum of parallel sides times its height.

$\text{Area of trapezoid}=\frac{h}{2}*(a+b)$ , where

h= Height of trapezoid,

a and b= Length of parallel sides of trapezoid.

We have been given that the height of the trapezoid is the width of the desk.

Upon substituting our given vales in above formula we will get,

$791=\frac{w}{2}*(26.5+30)$

$791=\frac{w}{2}*(56.5)$

$791=w*28.25$

$w=\frac{791}{28.25}$

$w=28$

Therefore, the width of trapezoid is 28 centimeters.

What is the measure of ∠x

scZoUnD [109]

Answer:

∠x = 63°

Step-by-step explanation:

The exterior angle added with the measure of ∠BAC will equal 180, since they will form a straight line, so we can calculate the measure of ∠BAC:

128 + x = 180

x = 52

∠BAC = 52°

The angles in a triangle all add up to 180°, so we can set up another equation to find x:

52 + 65 + x = 180

117 + x = 180

∠x = 63°

A solid object in the shape of a cylinder is shown below.

lozanna [386]

Answer:

$0.08\ kg/m^3$

Step-by-step explanation:

Density is defined as mass of an object divided by its volume.

#We calculate the volume of the cylinder:

$V=\pi r^2 h, r=D/2=6/2=3\ cm\\\\=3.14\times 3^2\times 7\\\\=197.82\ m^3$

Given the mass= 15.3kg and volume as above, we calculate density as:

$\rho=\frac{Mass}{Volume}\\\\=\frac{15.3\ kg}{197.82\ m^3}\\\\=0.0773\approx 0.08\ kg/m^3$

Hence, the solid's density is $0.08\ kg/m^3$
