Mathematics

TEA [102]3 years ago
4 0

Answer:

-2

(The coordinate point is (0,-2))

Step-by-step explanation:

First, make an equation of the line.

Start off with finding the slope:

Slope = (13-1)/(5-1) = 12/4 = 3

Then solve for the y-intercept though substitution and simplification:

y=mx+b --> 1=3(1)+b --> 1=3+b --> b= -2

So the answer is -2.

Elena’s bedroom door is 0.8 m wide. How wide should the door be on the scale drawing, if the ratio is 1 to 50?
arlik [135]

We are given Elena’s bedroom door's width = 0.8 m.

Also the scale drawing is in the ratio of 1 to 50 that is 1/50.

<em>In order to find the width of  scale drawing, we need to multiply original width of the door by 1/50.</em>

If we multiply 0.8 by 1/50, we get

0.8 × 1/50 = 0.8/50 = 0.016 meter.

So, we can say 0.016 meter wide should the door be on the scale drawing, if the ratio is 1 to 50.

You want to place a towel bar that is 10 1⁄4 inches long in the center of a door that is 26 1⁄3 inches wide. How far should you
djverab [1.8K]
First we want to find the part of the door not covered by the towel bar.

So subtract 10.25 from 26.33

In order to do this we need common denominators

So we multiply the fractions to get

(26 & 4/12) - (10 & 3/12)

Now we subtract to get

15 & 1/12

Since the 15 is odd, add 12/12 to the fraction

14 & 13/12

Now divide that in half to get the distance from each edge

7 & 13/24

the temperature dropped 2°F every hour for 6 hours. What was the total number of degrees the temperature changed in the 6 hours?
Assoli18 [71]

Answer:

-12 °F

Step-by-step explanation:

To find the total change in temperature, multiply 6 by -2, since it dropped 2 degrees each hour for 6 hours.

6(-2)

= -12

This means -12°F was the total number of degrees the temperature dropped.
