The top of the desk is shaped like a trapezoid the bases of the trapezoid are 26.5 and 30 cm long the area of the desk is 791 CM

kotegsom [21]

Answer:

28 cm

Step-by-step explanation:

Given that :

Area = 791 cm

Base, b1 = 26.5 cm

Base, b2 = 30 cm

Area, A of trapezoid :

A = 1/2 (a + b) h

Where a and b are the bases ;

791 = 1/2(26.5 + 30)h

791 = 0.5(56.5)h

791 = 28.25h

h = 791 / 28.25

h = 28 cm

Colin loves to play the piano but doesn't like practicing the exercises his piano teacher assigns. Colin

kati45 [8]

The linear equation for the number of cookies he receives, for x hours practicing the piano, is:

$y = x + 10$

A <u>linear function</u> has the format given by:

$y = mx + b$

In which:

m is the slope, which is the rate of change.
b is the y-intercept, which is the value of y when x = 0.

In this problem:

We have two points: (5,15) and (10,20).
The slope is given by <u>change in y divided by change in x</u>, then:

$m = \frac{20 - 15}{10 - 5} = \frac{5}{5} = 1$

Then

$y = x + b$

Point (5,15) means that when $x = 5, y = 15$ , which is used to find b.

$15 = 5 + b$

$b = 10$

The, the function is:

$y = x + 10$
