Answer:

-10, 20 because -20, 40 divided by 2 = -10, 20

The ordered pair that would form a proportional relationship with the point (-20, 40) is given as follows:

(15, -30).

A proportional relationship is a relationship in which a constant ratio between the output variable and the input variable exists.

The equation that defines the proportional relationship is a linear function with slope k and intercept zero presented as follows:

y = kx.

The slope k is the constant of proportionality, representing the increase or decrease in the output variable y when the constant variable x is increased by one.

The constant for this problem is given as follows:

k = 40/-20

k = -2.

Hence the equation is:

y = -2x.

When x = 15, the numeric value of the equation is given as follows:

y = -2(15)

y = -30.

Hence the point is:

(15, -30).

Answer:

Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.

It says that three-fourth of the total weight is metal and says to find the weight of wooden part.

We can find the weight of metal part and then subtract it from the total weight to calculate the answer.

Step-by-step explanation:

Total weight = 14.9 kilograms.

Metal part = three-fourth of total weight =

Wooden part = 14.9 - 11.175 = 3.725 kilograms.

Hence, the wooden part is 3.725 kilograms.

Answer:

-21/5 = -5.25 or -5

Step-by-step explanation:

It is so because I estimated the -21.87 to -21 because of the 8 being higher than five. I estimated the 4 to 5 because of the 7 being higher than five also.

(4)(25) - 300 can be written as an addition equation: 100 + (-300).

An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.

Given:

An equation is (4)(25)-300.

To write (4)(25)-300 as an addition equation,

we can break it down into two separate addition equations as follows:

(4)(25) - 300 = (4)(25) + (-300)

To solve this further,

substitute the value 25 x 4 = 100 to the above equation, we get,

= 100 + (-300)

Therefore, the equation in the required form is  100 + (-300).

Answer:

Nope

Step-by-step explain

1+5=6

6/5 is not 1

2+5=7

7/5 is not 2

NO, a whole number can't be 5 more than another number, & 5 times another number.

Let a whole number be = n

5 more than whole number = n + 5 ; And 5 times the whole number = 5n

Equating them , n + 5 = 5n

5n - n = 5

4n = 5

n = 5 / 4

5 / 4 is not a whole number, as it is in fractional form.

Also, 5/4 + 5 = (5 + 20) / 4 = 25 / 4

5 / 4 x 5 = 25 / 4

Both above sum & product are also in fractional form, so are not whole numbers.

Hence proven.

Answer:

The volume of the prism is the area of the base times the height. So to calculate height, divide the volume of a prism by its base area. For this example, the volume of the prism is 500 and its base area is 50. Dividing 500 by 50 results in 10.

Answer: The correct answer is - 50.

Step-by-step explanation: :)

Answer:

50

Step-by-step explanation:

To calculate the mean, we do the total divided by the number of values. Therefore, to get 30, with 7 values, we need to have a total of 210. Currently, we have a total of 160, so Saturday needs to be 50, because 210-160=50.

Answer:

$16

Step-by-step explanation:

So Sapatra spent $80 at Mr. and Mrs. Crab and She left a tip of 20%. We can convert  20% into a decimal, that would be .2 when you move your decimal from the left 2 times and multiply 80 by .2. meaning her tip she left is $16

Answer:

4021.2 cm³

Step-by-step explanation:

you start by getting the radius, the radius is half the diameter which in this case half of 16 is 8 so 8 is your radius and you already know the height which is 20, now that we have the radius and the height we can start

the formula for finding the volume of a cylinder is πr² · h

so are formula would be π8² · 20 which turns into π64 · 20 which then turns into 1280π or 4021.238...

which you then said we need to round the nearest tenth so 4021.238 to the nearest tenth is 4021.2 cm³
