Answer:

20%

Step-by-step explanation: So 40 percent = 100 percent. If you divide 40 percent by 5 you get 8. 1/5 is equal to 20% and 8 is a fifth of 40. So the answer is 20%.

We have that the 8 is 40 percent of 20 and it  is mathematically given as

x=20

Question Parameters:

8 is 40 percent of what number

Generally the equation for the statement  is mathematically given as

x*40%=8

Therefore

x*40%=8

x*0.4=8

x=20

The baker used 2 1/3 cups of pastry flour per cup of wheat flour.

To find out how many cups of pastry flour are used per cup of wheat flour, we can set up a proportion based on the given information:

3 1/2 cups pastry flour / 1 1/2 cups wheat flour = x cups pastry flour / 1 cup wheat flour

We can solve for x by cross-multiplying:

(3 1/2)(1) = (1 1/2)(x)

7/2 = 3/2x

Now we can solve for x by dividing both sides of the equation by 3/2:

(7/2) ÷ (3/2) = x

7 ÷ 3 = x

x = 2 1/3

Therefore, the baker used 2 1/3 cups of pastry flour per cup of wheat flour.

The diameter of the new cell, which is exactly half the diameter of the original cell (4.32 x 10^-4 millimeters), is 2.16 x 10^-4 millimeters.

The lab technician is dividing a cell with an original diameter of 4.32 x 10^-4 millimeters. The new cells' diameter is stated to be exactly one half of the original diameter. Therefore, to find the diameter of the new cell, simply take half of the original cell's diameter. This can be accomplished by dividing the numerical value of the diameter by 2, which would be 4.32/2 = 2.16. The exponent remains the same because the size (magnitude) of cell diameter is only halved, not the order magnitude. So the diameter of the new cell is 2.16 x 10^-4 millimeters.

The number of cups required to make 30 cups of donuts toppings=18 cups

Answer:

Quotient = 0.16, Remainder = 0    

Step-by-step explanation:

Standard algorithm of division is a step by step procedure to perform division.

In this question we have to divide 0.64 by 4, therefore, 0.64 is the dividend and 4 is the divisor.

Steps:

Zero times four is 0. Then we put decimal point in our quotient.

Continuing one times 4 is 4. We subtract 4 from 6 to have remaining value of 2. Then, we copy down 4. Thus, the remaining value now is 24.

Six times four is 24. Thus, the remaining value is zero.

Hence, we get the remainder of zero and quotient 0.16.

When 0.64 is divided by 4 using standard algorithm, we get 0.16.

Division in maths is the process of breaking a number up into equal parts, and finding out how many equal parts can be made.

Given is 0.64 divided by 4.

In order to divide 0.64 by 4, follow the given steps -

1 : 4 multiplied by 0 is equal to 0. Start writing the quotient as by writing 0 and decimal point after it.

2 : 4 multiplied by 1 is 4 and when 4 is subtracted from 6, we get 2. The quotient will now become 0.1 . Bring 4 down, next to 2.

3 : Now, 24 divided by 4 gives 6, this will leave remainder 0 and the final quotient will be 0.16

Therefore, 0.64 divided by 4 using standard algorithm, we get 0.16.

The summation of 10 yds and fifteen yds is 25 yds thus the ball is the on 25 yd line and the zero represents the ball is in the net and goals.

The summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.

There could be only two terms, but there could be one hundred, a thousand, or a million.

As per the given question,

The initial position of the ball = 10 yd line

The team gained 15 yds in the first play.

Therefore, New position of the ball = 10 yds + 15yds = 25 yds

Hence "The summation of 10 yds and fifteen yds is 25 yds thus the ball is the on 25 yd line and the zero represents the ball is in the net and goals".
