Answer: 120

Step-by-step explanation:

2 = 240

240 / 2 = 120

unit = per

so the answer will be 120 calories

Answer:

2:240 or 2/240, whichever you like better. If you need a single unit answer, you would just divide this rate shown by 2 in order to get 1/120 or 1:120

Step-by-step explanation:

Every single part of the chart adds the first number. 2+2=4+2=6+2=8

Same thing with the bottom, 240+240=480+240=720+240=960.

The unit rate would be 2/240 by that logic, because for every 2 servings there are 240 calories.

Answer:

Volume of solid = 737 cm³ (Approx)

Step-by-step explanation:

Given:

Radius r = 4 cm

Length of cylinder = 12 cm

Find:

Volume of solid

Computation:

Volume of solid = Volume of hemisphere + Volume of cylinder

Volume of solid = (2/3)πr³ + πr²h

Volume of solid = (2/3)π(4)³ + π(4)²(12)

Volume of solid = 134 + 603

Volume of solid = 737 cm³ (Approx)

Answer:

737.23

Step-by-step explanation:

formua for sphere:

V = 4/3 πr^3

so the volume would be 268.08

divide by 2 bc its only half of a sphere

you get 134.04

formula for cylinder:

V = πr^2h

so the vlume would be 603.19

add the volumes together you get 737.23

Answer:

60 inches

Step-by-step explanation:

There are 12 inches in a foot.

There are 3 feet in a yard.

With this information, Joe is 5 feet away from finishing the race, but we need that answer in inches.

So if one foot equals 12 inches, we will simply multiply:

5ft × 12 in = 60 inches

Answer: 6 jars

Step-by-step explanation:

All you need to do is divide 2 by 1/3. This is the same thing as multiplying 2 by the reciprocal of 1/3 (just flip the fraction) which is 3/1 or 3. Now, just multiply 2 and the reciprocal of 1/3, which we found out was three, and you should should get your answer of 6 jars. Hope this helps!

Answer:

4x + 12

Step-by-step explanation:

If we simply we get this expression we get....

5x + 2 - x + 10 = 4x + 12

4x + 12 is also an expression and it has the same result as the one show in the question, and this is why it is the right answer.

Answer:

4x+12

2(2x+6)

Thats all I can think of

Answer: √32

Step-by-step explanation: so the displacement is north 4 and west 4 and it becomes a right triangle so the hypotenuse is the distance for segment AB

So Drawn out should like straight lines up,down,left,and right. So east is positive while west is negative same for North(+) and South(-)

I recommend sticking with 2 directions first. Starting with north and south right. First you go south 1 mile but then you go north 5miles in math terms

-1+5=4 or down one is one less than 5

Same for east and west. 3+-7 = -4

So we went positive 4 miles up and 4miles to the left

So (-4)^2+4^2= hypotenuse or AB segment in this case

Answer:

Answer:

$11.20 per hat.

and $5.60 per bag

Keisha has $13.20 left over

Step-by-step explanation:

First, I multiplied .70 by 16 and got 11.20 per hat

Then, I multiplied .35 by 16 and got 5.60 per bag

Lastly, I added 11.20 to 5.60 and got 16.80, and subtracted 16.80 from  30 and got 13.20.....

Answer:

Step-by-step explanation:

In the first triangle, using Pythagorean's theorem, x^2+3^2=5^2, x = 4

In the second triangle, using Pythagorean's theorem, x^2+7^2=24^2, x = 25

In the third triangle, using Pythagorean's theorem, 8^2+15^2=x^2, x = 17

In the fourth triangle, using Pythagorean's theorem, x^2+8^2=10^2, x = 6

In the fifth triangle, using Pythagorean's theorem, 5^2+12^2=x^2, x = 13

Answer:

-3/4

Step-by-step explanation:

You just start at the lowest point on the graph, count how many points it goes up which is 3, then you go left 4. So you have 3/4, but because you went left it is -3/4

Answer:

Answer:

the answer is 3

Step-by-step explanation:

There are 3 number of items must be sold in order for the supply and demand to be equal.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

An economic model predicts that the supply, s, and the demand, d, for a new product can be estimated using the lines on the graph.

Now,

In the graph, The two line intersect at a point (3, 48).

So, We can say that;

There are 3 number of items must be sold in order for the supply and demand to be equal.

Thus, There are 3 number of items must be sold in order for the supply and demand to be equal.

Answer: y = 3, x = 5

Step-by-step explanation:

Solution by substitution method

4x+y=23

3x-y=12

Suppose,

4x+y=23→(1)

and 3x-y=12→(2)

Taking equation (1), we have

4x+y=23

⇒y= -4x+23→(3)

Putting y= -4x+23 in equation (2), we get

3x-y=12

3x-1(-4x+23)=12

⇒3x+4x-23=12

⇒7x-23=12

⇒7x=12+23

⇒7x=35

⇒x=5→(4)

Now, Putting x=5 in equation (3), we get

y=-4x+23

⇒y=-4(5)+23

⇒y=-20+23

⇒y=3

∴y=3 and x=5

Perimeter = 8pi

Step-by-step explanation:

The Rim if the leaf like shape is actually the quarter fo a circle. and 8 is the radius. So to find the perimeter is diameter time pi so 16 x pi is 16pi. And because its only a quarter its 4pi. Also, because there is 2 ramps 4pi times 2 is 8pi. So the answer is 8 pi.
