Answer:

The slope is -2 and the slope-intercept form is y=-2x+20

Step-by-step explanation:

To find the slope between two points, remember to use the equation y2-y1 over x2-x1. That will help you get the slope. To find the y-intercept, use any of the two points given and insert the slope into the equation y=mx+b. For this one I used the two points (7,6)

What’s the surface area in square units if right I’ll mark brainleiest

erik [133]

Answer: 349 square units

============================================

Work Shown:

L = 5.5 = length
W = 5 = width
H = 14 = height

SA = surface area of rectangular prism

SA = 2*(L*W + L*H + W*H)

SA = 2*(5.5*5 + 5.5*14 + 5*14)

SA = 2*(27.5 + 77 + 70)

SA = 2*(174.5)

SA = 349

The surface area is 349 square units.

the length of your stride is 30 inches, if you walk 10,000 steps in a day, how many miles will you walk? Rounded to the nearest

Taya2010 [7]

Answer:

4.7 miles

Step-by-step explanation:

10, 000 steps (stride) * 30 inches per stride = 300,000 inches per day.

To know miles, we need the miles-to-inches conversion, which is:

1 miles = 63,360 inches

To find number of miles walked in a day, we would need to divide total (300,000) by 63,360 :

$\frac{300,000}{63,360}=4.73$

So, that 4.73 miles a day

Rounded to nearest tenth, 4.7 miles per day

Nonamiya [84]

Answer:

23.09 ft

Step-by-step explanation:

Here we are given that the angle from stake in ground to the top of the tree is 60° and the height of the tree is 40ft . We are interested in finding out the distance from stake to the bottom of the tree . For figure refer to the attachment .

From the figure , BC = 40ft which is the perpendicular of the right angled triangle ABC . Also assume that AB = x ft , which is the base of the triangle .
