Steve has 18 blue marbles and 27 red marbles in a bag. What is the ratio of red marbles to
blue marbles?

Answer:I’m guessing the second one

Step-by-step explanation:

I thinking that because if u add it all up also this is just a thought

Answer:

dw i got u

3*5.2=15.6 we solve for both triangles

15.6*2=31.2

6*7*3=126 solve for the three long rectangles

126+31.2=157.2 and we add up

So option 2

Answer:

Volume = length x width x height.

You only need to know one side to figure out the volume of a cube.

The units of measure for volume are cubic units.

Volume is in three-dimensions.

You can multiply the sides in any order.

Which side you call length, width, or height doesn't matter.

Answer:

Step-by-step explanation:

Corresponding sides should have same ratio:

Solve for y:

Correct choice is B

Answer:

4 times 4 times 4 times 4 times 4

Answer:

150cm²

Step-by-step explanation:

area of 1 face=5*5=25cm²

A cube has 6 faces so you have to find the area of 6 faces to find complete surface area.

If 1 face = 25cm²

6 faces =25cm² x 6

=150cm²

Answer:

dT/dt = k(T-75)

Step-by-step explanation:

dT/dt = the rate of change of the egg's temperature T with respect to time t

k = constant

(T-75) = difference between the egg's temperature and the room temperature 75 degree

The relationship between the temperature of the egg and that of the room is dT/dt = k(T-75).

From the Newton's law of cooling, the rate of cooling of any object depends on the temperature difference between the object and the surroundings. This is usually expressed in a differential equation.

In this particular instant, the differential equation that shows the relationship between the temperature of the egg and that of the room is dT/dt = k(T-75).

Answer:

28.9 miles per gallon

Step-by-step explanation:

unit rate is usually something per something. Like miles per hour. In this case we have mile per gallon. MPG.

Unit rate is basically A number X per 1 of something.

so in this cares X per gallon.

we want 10 gallons to go to 1 gallon. So we divide by 10 to get to 1. But if we divide by 10 on one side, we have to do it to the other side. so 289/10=28.9

so our final answer is:

28.9 miles per gallon

Answer:

B. 5/3

Step-by-step explanation:

Take out the fourth root by doing 20/4 = 5. Then take out the third root by doing 5/3 so your answer is 5/3

Answer:

Answer = 5/3

Step-by-step explanation:

We simplify the squareroot to become ((x-5)^20)^1/12. Simplifying this further will get us (x-5)^5/3. We know that "b" is the exponent on (x-5), therefore the answer is 5/3.

Answer:

4 : 1

Step-by-step explanation:

1 hour : 15 minutes

However we cannot write like this since they aren't of the same unit, so you can either change the minutes to hour by dividing it with 60 or change the hours to minutes by multiplying it with 60.  

1 hour = 60 minutes

60 : 15

The ratio can be simplified.

12 : 3  ( 60 and 15 are multiples of 5 )

The ratio can again be simplified further.

 4 : 1   ( 12 and 3 are multiples of 2 )

= 180(16-2)

= 2520 degrees.

Answer:

trapezium

If the shape you're looking at doesn't have at least one set of parallel sides, it's not a trapezoid; it's something called a trapezium instead. Similarly, if the shape has two sets of parallel sides, it's not a trapezoid. It's either a rectangle, a parallelogram shape or a rhombus.

Answer:

Step-by-step explanation:

area = 30x + 30(x+3) + 30(2x)

= 30x + 30x+90 + 60x

= (120x + 90) m²

length of planting area = x + (x+3) + 2x = 4x+3 m

area = 30(4x+3) = (120x + 90) m²

x = 5

maple area = 30(5+3) = 240 m²

locust area = 30(2·5) = = 300 m²
