1 answer:
gizmo_the_mogwai [7]2 years ago
8 0

Answer:

B is the answer

Step-by-step explanation:

A = πr²

24π = πr²

24 = r²

24 = r²

\sqrt{24} = r

r = \sqrt{4}\sqrt{6} = 2\sqrt{6}

C = 2πr

C = 2π(2\sqrt{6})

C = 4\sqrt{6}π

What is a 15% tip on a meal that costs $25.00
nataly862011 [7]
25.00/ 10= 2.50
 \\ 2.50*1.5= 3.75 \\ 25.00+3.75= 28.75
As you've got 15%, the best thing to do is to find 10%, then multiply it by 1.5. Once you've found the tip, you add this onto the cost of the meal.
Therefore, the total cost of $25 meal with a 15% tip is $28.75
Hope this helps :)

A shipping container will be used to transport several 140-kilogram crates across the
velikii [3]

Answer:

91.42 crates

Step-by-step explanation:

Let

Greatest Number of 140kg crates = x

weight of crate = 140-kilogram

Weight of other shipment = 13200 kilograms

greatest weight of container = 26000 kilograms

Weight of other shipment + (weight of crate * number of crates) ≤ greatest weight of container

13,200 + 140x ≤ 26,000

140x ≤ 26,000 - 13,200

140x ≤ 12,800

x ≤ 12,800/140

x ≤ 91.42 kilograms

Greatest Number of 140kg crates = 91.42 crates

What do you round 150 to??
Vedmedyk [2.9K]
It depends on what you are rounding off to.

If you are round it off to the nearest ten, you must look at the unit number.
If you are rounding off to the nearest hundred, you must look at the ten number.

In this case I think they are asking to round to the nearest hundred. Now we must look at the ten number, which is the number after the 'hundred' number.

The ten number is '5' and the hundred number is '1'. If the ten number is 5 or above, it changes to 0 and it makes the hundred number one higher.

So because the ten number is 5, it changes to 0 and it makes the hundred number one higher, to become 2.

The number is now 200.

What are the y and x intercepts for -5x-4y=10
KatRina [158]

Answer:

x-intercept(s) = (-2,0)

y-intercept(s) = (0, - 5/2)

Step-by-step explanation:

the x-intercept, substitute in  0  for  y  and solve for  x . To find the y-intercept, substitute in  0  for  x  and solve for  y .

x-intercept(s) = (-2,0)
