Answer:

22.

Step 1: Find area of inner square = 4 ft × 12 ft = 48ft2

Step 2: Find area of outer shape =

25 ft +11 ft = 36 cm2

Step 3: Area of shaded region = area of outer shape – area of inner square

= 36 ft2 – 48 ft2

= 12 ft2

Consider the diagram below. which of the following represents the values x,y and z?
Gemiola [76]

Answer:

x=4\sqrt{6}\ units

y=4\sqrt{2}\ units

z=4\sqrt{3}\ units

Step-by-step explanation:

The picture of the question in the attached figure

step 1

In the right triangle ABD

Applying the Pythagorean Theorem

x^2=y^2+(12-4)^2

x^2=y^2+64

y^2=x^2-64 ----> equation A

step 2

In the right triangle BDC

Applying the Pythagorean Theorem

z^2=y^2+4^2

z^2=y^2+16

y^2=z^2-16 ----> equation B

step 3

In the right triangle ABC

Applying the Pythagorean Theorem

12^2=x^2+z^2

144=x^2+z^2 ----> equation C

step 4

Equate equation A and equation B

x^2-64=z^2-16

x^2=z^2+48 -----> equation D

step 5

substitute equation D in equation C

144=z^2+48+z^2

solve for z

2z^2=144-48

2z^2=96

z^2=48

z=\sqrt{48}\ units

simplify

z=4\sqrt{3}\ units

Find the value of x

x^2=z^2+48

x^2=48+48=96

x=\sqrt{96}\ units

x=4\sqrt{6}\ units

Find the value of y

y^2=z^2-16

y^2=48-16

y^2=32

y=\sqrt{32}\ units

y=4\sqrt{2}\ units

a plumber charges $55 for a service call, plus $35 per hour. If the plumber bill was $160 ,then how many hours was he there
marysya [2.9K]

Answer:

he was there 3 hours

Step-by-step explanation:

so you take 160 and subtract 55 from that number

160-55=105

next take 105 and divide that by 35 to get how many hours he was there.

105÷35=3

if you need this in slope intercept for a graph you use the equation where y = the total money spent

y=35x+55
