Answer:

18. 20,000.

19. 0

7. 1

11. 101

Step-by-step explanation:

18. I think is stays the same, because an integer is a number that is not a fraction. So still 20,000.

19. Sea level is at zero altitude. So answer is 0.

7. |17-16| = |1| = 1. The lines around it are called absolute value signs and mean to make the answer positive.

11. |-101| = 101. As said before the lines mean to make the inside part positive.

Sam is driving from Chicago to San Francisco, a distance of 2220 miles. He covers the first 192 miles in 4 hrs. At this rate, ho
Citrus2011 [14]
We can set it up like this:

\frac{192}{4} = \frac{2220}{x}

This states that Sam can drive 192 miles in 4 hours and 2220 miles in x hours.  To solve, we can use cross-multiplication:

192x = 2220*4 \\ 192x = 8880 \\ x = \frac{8880}{192} \\ x = 46.25

It will take Sam 46.25 hours to drive the whole trip, or 46 hours and 15 minutes.

A ship leaving port sails for 75 miles
ziro4ka [17]

Answer:

Vertical= 61.43 miles

Horizontal=43.02 miles

Step-by-step explanation:

We use the trigonometric ratios for a right angled triangle to calculate the components.

The vertical is the adjacent while the horizontal is the opposite.

The vertical is calculated as follows:

V= 75 Cos 35° =61.43 Miles

The magnitude of the horizontal H is calculated as follows:

H= 75 Sin 35° = 43.02 miles

Which could be the dimensions of a rectangular prism whose surface area is greater than 140 square feet? Select three options,
ElenaW [278]

Answer:

These are the rectangular prisms that have a surface area greater than 140 square feet

6 feet by 5 feet by 4 feet

7 feet by 6 feet by 4 feet

8 feet by 3 feet by 7 feet

Step-by-step explanation:

The formula to find the surface area of a rectangular prism is SA=2(wl+hl+hw)

All you have to do is go through all the options given to you to figure out which retangular prisms have a surface area greater than 140 square feet.

6 feet by 2 feet by 3 feet

SA = 2((2)(6)+(3)(6)+(3)(2))

SA = 2(12 + 18 + 6)

SA = 2(36)

SA = 72

6 feet by 5 feet by 4 feet

SA = 2((6)(5) + (4)(5) + (4)(6))

SA = 2(30 + 20 + 24)

SA = 2(74)

SA = 148

7 feet by 6 feet by 4 feet

SA = 2((7)(6) + (4)(6) + (4)(7))

SA = 2(42 + 24 + 28)

SA = 2(94)

SA = 188

8 feet by 3 feet by 7 feet

SA = 2((8)(3)+(7)(3)+(7)(8))

SA = 2(24 + 21 + 56)

SA = 2(101)

SA = 202

8 feet by 4 feet by 3 feet

SA = 2((8)(4)+(3)(4)+(3)(8))

SA = 2(32 + 12 + 24)

SA = 2(68)

SA = 136

I need help on this problem
Serga [27]

answer: y = 3/2x - 2


how i got the answer:

<em>slope intercept form: y = mx + b (slope = m , y-intercept = b)</em>

<em>with this form, any value for y or x should work and have one true solution.</em>

so, let's start by finding the y intercept, or what y is when x = o. in this case, it looks like it's -2, so we can add that to the equation.

y = mx - 2

to find the slope, let's plug a y and x value in the graph into the equation to isolate m and get our slope.

let's use the point (2,1)

1 = (2)m - 2

1+2 = 2m -2+2

3 = 2m

3/2 = 2m/2

\frac{3}{2}  = m

the slope is 3/2. lets add that to the rest of our equation:

y = 3/2x - 2

now that we have the slope value, our equation is complete!

there you go! hope this helps, and have a great day!
