Step-by-step explanation:

0.001374

standard form means writing a value in shortened form, because sometimes values are too big or small to be written, so we use standard form.

in standard for the decimal always comes after the first digit

so,

1.374 \times  {10 }^{ - 3}

the decimal moves 3 digits to the right so it becomes ten raised to the power minus 3.

9. B

For number 6, 10 vans times 12 students is 120 students. 432 - 120 = 312. 312 students divided by 6 buses is 52. To check if it right I tried Middle School B. 5 vans times 12 students is 60. 164 students - 60 = 104. 104 divided by 2 buses equals 52. So 12 students is the right answer.


For number 9, 35*2=70 and 15*5=75. 70+75=145.

A company rents water tanks shaped like cylinders. Each tank has a radius of 3 feet and a height of 2 feet. The cost is $ 4 per
Alexxandr [17]

Answer:

The total cost of the cylindrical tank is $226.28

Step-by-step explanation:

Dimensions of the tank are:  radius = 3 ft , height = 2 ft

Cost per cubic foot = $4

Now, total volume of the cylindrical tank =  \pi \times r^{2}h

Here, take π = 22/7

So, Volume  = \frac{22}{7}  \times (3)^{2} \times (2) = \frac{22 \times 9 \times 2}{7}  = \frac{396}{7}  = 56.57 cubic ft

So, the <u>volume of the tank = 56.57 cubic feet. </u>

Now, cost per cubic foot = $4

Hence, the total cost of the tank = Total Volume of the tank x cost per foot

                                                       = 56.57 x 4 = $226.28

So, the total cost of the cylindrical tank is $226.28

C. Find a parametrization for the line segment with endpoints (-1, 3) and (3, -2).
wel

Answer:

x(t) = -1 + 4t

y (t) = 3 - 5t

Step-by-step explanation:

The end points of the line segment are (-1, 3) and (3, -2).

Let a = (-1,3) and b = (3,-2)

Now, find the value of (b-a)

(b-a) = ((3+1), (-2-3))

b-a = (4, -5)

Therefore, the parametrization of the given line segment is

r(t) = a + (b-a)t

r(t) = (-1,3) +(4,-5)t

r(t) = (-1+4t, 3-5t)

We can rewrite this as

x(t) = -1 + 4t

y (t) = 3 - 5t

PLEASE ANSWER THiS MATH QUESTION !! 20 POINTS AND BRAINLIEST !!
RoseWind [281]

Answer:

A

Step-by-step explanation:

Plug in the values of each of the coordinate pairs into the linear system.

2x - 8y = 0, -3x - 8y = 20

A)

2*-4 - 8*-1 = 0

- 8 - (-8) = 0 -> CORRECT!

-3x - 8y = 20

-3*-4 - 8*-1 = 20

12 - (-8) = 20 -> CORRECT!

You don't need to try any other pairs, you already know that this is the solution to the problem! Remember, in the future, just plug all the coordinate pairs into the equation. Whichever one makes the equation true is the correct solution! Hope this helps!
