Answer:

Multiplying a number by 10 makes calculations much easier

Step-by-step explanation:

To multiply a number by [tex]10^{n}[/tex], add n zeroes to a number.

For example, 25×1000=25×10³=25000

Consider the following pattern:

[tex]5\times 10=50\\5\times 10^2=500\\5\times 10^3=5000\\5\times 10^4=50000\\5\times 10^5=500000\\5\times 10^6=5000000[/tex]

So, basic rules of multiplying a number by 10 makes calculations much easier.

Foe example consider the following example:

[tex]26\times 20\times 30=26\times (2\times 10)\times (3\times 10)=26\times 6\times 100=15600[/tex]

How many % of 50 shirts 35 shirts

Answers

Do you mean what percent is 35 of 50? I can help with that. Well since a percent is out of 100 you can multiply 50 by 2 to get to 100. But then you would also have to multiply 35 by 2. This will get you 70 out of 100. Which would make it 70 percent. Both number are proportionate so 70 would be your answer. But since this doesn't work for most others another way to solve it is to divide 35 by 50. And you get 0.7 Which it seventy-tenths of one hundred. Or 70 percent. So you could work this one both ways. But your final answer would be 70% no matter which you do.

Answer:

C


Step-by-step explanation:

f(p) is the average number of days a house stays on the market before being sold for price p in $1,000s

A little more clearer explanation:

p is the price in $1000s, andf(p) is the number of days before its sold for p

Hence, f(250) would be the number of days before its sold for 250,000 (since p is in $1000s)

Answer choice C is the correct one.

what is the value of the second one in 15.186

Answers

Then 5 is ones and the 8 is hundrths
The second 1 in 15.186 is the one to the right of the decimal point, so the value is 1 tenth or 1/10.
Remember that when you're working with decimals the numbers to the right of the period go like this: Tenths, hundredths, thousandths and so on. So the total value of the numbers to the right of the decimal point is 186 thousandths or 186/1000.

it raind during 40% of the days of Chrissys vacation. if it rained on 2 days how many days long was chrissys vacation

Answers

Chrissy's vacation would have been 5 days total. To find this, you can set up a proportion. I did 40 over 100, (40%), equals 2 over x. You cross multiply 2 and 100. You take that number, 200 in this case, and divide it by 40 to get the variable by itself. This would leave you with what the variable equals, 5.
Final answer:

To find the length of Chrissy's vacation, use the proportion of rainy days to determine the total number of days, resulting in a 5-day vacation.

Explanation:

To find the total number of days in Chrissy's vacation, we can use the fact that it rained on 40% of the days, which is equal to 2 days. From this, we can set up a proportion to solve for the total days. So, if 40% equals 2 days, 100% equals how many days?

Set up a proportion: 40% = 2 days and 100% = x days.Cross multiply: 40 * x = 2 * 100Solve for x: x = (2 * 100) / 40Calculate x: x = 5

Therefore, Chrissy's vacation was 5 days long.

In a sale, normal prices are reduced by 20%. Andrew bought a saddle for his horse in the sale. The sale price of the saddle was £220. Calculate the normal price of the saddle

Answers

The formula for this is: (sale price) / (1 - percentage)
Percentage have to be in decimal form, so divide percentage by 100 to get the decimal form.

220/(1-.20) = $275

The original price was $275. 

The normal price of the saddle, x = £275.

To find the normal price of the saddle:

Let the normal price be x.

Since the sale price is £220, which is 80% of the normal price, you can set up the equation: 0.80x = £220.

Solve for x: x = £220 / 0.80 = £275.

leila uses 5 cups of grated zucchini to make 2 loaves of zucchini bread.How many cups of zucchini does she need to make 1 loaf ?

Answers

If you take 5 divided by 2, you would get 2.5 cups of zucchini per loaf.
Final answer:

To make 1 loaf of zucchini bread, Leila needs 2.5 cups of zucchini.

Explanation:

To find out how many cups of zucchini Leila needs to make 1 loaf, we can set up a proportion. Since she uses 5 cups of zucchini to make 2 loaves, we can say that 5 cups is to 2 loaves as x cups is to 1 loaf. We can set up the proportion as:



5 cups / 2 loaves = x cups / 1 loaf



Now we can cross-multiply and solve for x:



5 cups * 1 loaf = 2 loaves * x cups



x = (5 cups * 1 loaf) / 2 loaves



x = 5/2 = 2.5 cups



Therefore, Leila needs 2.5 cups of zucchini to make 1 loaf.

Is x + 10 a factor of the function f(x) = x3 − 75x + 250? Explain.
Yes. When the function f(x) = x3 − 75x + 250 is divided by x + 10, the remainder is zero. Therefore, x + 10 is a factor of f(x) = x3 − 75x + 250.

No. When the function f(x) = x3 − 75x + 250 is divided by x + 10, the remainder is zero. Therefore, x + 10 is not a factor of f(x) = x3 − 75x + 250.

Yes. When the function f(x) = x3 − 75x + 250 is divided by x + 10, the remainder is not zero. Therefore, x + 10 is a factor of f(x) = x3 − 75x + 250.

How much interest is earned in 2 years on an investment of $2000? The interest rate is 3%

Answers

The amount of interest that is earned after two years will be $121.8.

What is compound interest?

A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.

We know that the compound interest is given as

A = P(1 + r)ⁿ

Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.

The investment is $2,000 with an interest rate of 3%.

Then the amount of interest that is earned after two years will be given as,

A = 2,000 (1 + 0.03)²

Simplify the expression, then we have

I = $2,000 (1 + 0.03)² - $2,000

I = $2,000 × (1.03)² - $2,000

I = $2,000 × 1.0609 - $2,000

I = $2,121.8 - $2,000

I = $121.8

The amount of interest that is earned after two years will be $121.8.

What is the value of the expression? −4.2 (0.35−3.5)

Answers

the answer comes out to be 13.23

Final answer:

The value of the expression −4.2 (0.35−3.5) is found by first solving the operation within the parentheses, resulting in −3.15, and then multiplying this result by −4.2 to get 13.23.

Explanation:

To calculate the value of the expression −4.2 (0.35−3.5), we first evaluate the operation inside the parentheses.

0.35 − 3.5 = −3.15

Now, multiply this result by −4.2:

−4.2 × (−3.15) = 13.23

Therefore, the value of the expression −4.2 (0.35−3.5) is 13.23.

Answers

The area of a rectangle is calculated by the product of the length and the width of the rectangle. We calculate as follows:

Area = 12 3/4 square inches = L x W
12 3/4 square inches = L x 2 1/8 inches 
L = 51/4 * 8/17
L = 6 inches

Area = 12 3/4 square inches = L x W
12 3/4 square inches = L x 2 1/10 inches 
L = 51/4 * 10/21
L = 255/7 inches
