What is the length of the diagonal of a cube with a side length of 5 cm? Round to the nearest tenth.

O 7.1
O 8.7
O 21.3
O 26.7

Answers

Answer 1

Answer:

8.7

Step-by-step explanation:

formula

d = sqrt(s^2 + s^2 + s^2)

d = sqrt(3*5^2)

d = sqrt(75)

d = 8.7

Where did I get the formula? If the cube sits on one of its faces then the diagonal of that face is sqrt(s^2 + s^2) = sqrt(2s^2)

Now to get the third s^2, you have to realize the the diagonal you calculated in the previous remark is one of the legs for the cube's corner to corner diagonal. The other leg is the height squared which is also s^2.

Sam is designing an open wooden box in the shape of a rectangular prism. The base of the box will be 6 feet by 8 feet. He has not yet decided what the height will be.

Answers

Answer:

10ft

Step-by-step explanation:

Let assume the volume of the box be 480ft^3

Required

height h

Volume of the box = length * width * height

Substitute

480 = 8 * 6 * h

480 = 48 * h

h = 480/48

h = 10ft

Hence the height of the box if the volume of 480ft^3 is 10ft

A line passes through the point (-4,-20) and has a slope of 3. Write an equation of the line satisfying the given conditions. Write the answer in slope-intercept form

Answers

Answer:

  y = 3x -8

Step-by-step explanation:

The point-slope form of the equation of a line can be a useful place to start.

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y +20 = 3(x +4) . . . . with given numbers filled in

  y = 3x +12 -20 . . . . eliminate parentheses, subtract 20

  y = 3x -8 . . . . . . . . slope-intercept form

2x - 3y = 16
3x + 2y = 11

Step-by-step explanation:

36 m^2 = bh/2

36·2 = bh/2·2

Cars A and B leave the same place and travel in the same direction along a straight road. Car A travels at 60 km/h and car B travels at 72 km/h. After how long will they be at 8km apart?

Answers

Answer:

Car A: 8 minutes

Car B: 6.67 minutes

Step-by-step explanation:

Car A: 60km evrery hour so,

1 km every minute, so he will be in 8km in 8 minutes.

Car B: 72km per hour so,

72/60 = 1.2 = 1.2 km per minute.

8/1.2 = 6.6666666666667 which is about 6.67 to the nearest hundredth.

Answer:

40 min

Step-by-step explanation:

Car A is traveling at 1 km/min (60/60)

Car B is traveling at 1.2 km/min (72/60)

Car B gains .2km on Car A for every minute they drive.

8km/.2 = 40

Mary Jo spends $1,450 to buy stock in two companies. She pays $15 a share to one of the companies and $20 a
share to the other. If she ends up with a total of 90 shares, how many shares did she buy at $15 a share and how
many did she buy at $20 a share?

Answers

Answer:

she bought 70 shares of the $15 shares

she bought 20 shares of the $20 shares

Step-by-step explanation:

this would be solved using simultaneous equation

let a = $15 shares

b = 20 shares

a + b = 90   equation 1

15a + 20b = 1450  equation 2

Multiply  equation 1  by 15

15a + 15b = 1350  equation 3

subtract  equation 3 from  equation 2

5b = 100

b = 20

substitute for b in  equation 1

20 + a = 90

a = 70
