Since that angle all together is 180, 100 is 2z-10 and z is 55
Sauron [17]3 years ago
3 0

Step-by-step explanation:

80+(2z-10)=180 {sum of angles in straight line is 180}

  • 80+2z-10=180
  • 70+2z=180
  • 2z=180-70
  • 2z=110
  • z=110/2
  • z=55

now, 2z-10=2×55-10

=110-10

=100

therefore z=55 & 2z-10=100

Joseph typed a 1200- word essay in 25 minutes.at this rate,determine how many words he can type in 45 minutes.
Deffense [45]
First you divide 1200 by 25 (1200/25) it comes out to 48. 
That means the he types at a rate of 48wpm. So then all you have to do is multiply 48 and 45 and you get 2160 words.

A cylinder has a base diameter of 14m and a height of 10m. What is its volume in cubic m, to the nearest tenths place?
VARVARA [1.3K]

Answer:

1539 cubic meters

Step-by-step explanation:

Hello, I can help you with this

to solve need  we will need these two equations

Step one

Remember

area of a circle

Area=\pi *\frac{diameter^{2} }{4}\\

Also, the volume of the cylinder

Volume= area of the circle * height

Volume=\pi *\frac{diameter^{2} }{4} *height\\

Step 2

put the values into the equation

Let

diameter= 14 m

height = 10 m

Volume=\pi *\frac{diameter^{2} }{4} *height\\\\Volume=\pi *\frac{(14\ m)^{2} }{4} *10\ m \\\\Volume=\pi *49\ m^{2} *10\ m\\Volume=1539.38\ cubic\ meters

I hope it helps,have a great day.

Please answer this question correctly for 25 points and brainliest!!
lesya692 [45]

Step-by-step answer:

Given an enlargement from preimage (ABC) to image (A'B'C').

Need to find scale factor.

Solution:

Scale factor = linear size of image / linear size of preimage.

From the accompanying diagram, we see that

L(preimage) = AC = 4 units

L(image) = A'C' = 12 units

Therefore

Scale factor = L(image) / L(preimage) = 12 / 4 = 3
