There are 8 brooms and 6 mops in a janitor's closet. what is the ratio of the number of mops to the total number of brooms and mops? . a: 4/3 . b: 3/7 . c: 7/3. d: 3/4

B.

Step-by-step explanation:

We are given that in a Janitor's closet

Number of brooms=8

Number of mops=6

We have to find the ratio of the number of mops to the total number of brooms and mops.

Total number of brooms and mops=8+6=14

Ratio of number of mops to the total number of broom and mops=6:14

Ratio of number of mops to the total number of broom and mops=

Ratio of number of mops to the total number of broom and mops=

Hence, the ratio of number of mops to the total number of broom and mops=

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
