it raind during 40% of the days of Chrissys vacation. if it rained on 2 days how many days long was chrissys vacation
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 = 5Therefore, Chrissy's vacation was 5 days long.

What is the value of the expression? −4.2 (0.35−3.5)
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.
How much interest is earned in 2 years on an investment of $2000? The interest rate is 3%
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.

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 ?
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.

how do basic facts and patterns help me multiply a number by a multiple of 10
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]

A little more clearer explanation:
p is the price in $1000s, andf(p) is the number of days before its sold for pHence, 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.

Use long division to convert the rational number 4/9 to its equivalent decimal form.
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
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.

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.
No. When the function f(x) = x3 − 75x + 250 is divided by x + 10, the remainder is not zero. Therefore, x + 10 is not a factor of f(x) = x3 − 75x + 250.
Answer:
yes, When the function [tex]f(x)=x^3-75x+250[/tex] is divided by x+10 , the remainder is zero.Therefore, x+10 is a factor of [tex]f(x)=x^3-75x+250[/tex]
Step-by-step explanation:
We are given that
[tex]f(x)=x^3-75x+250[/tex]
We have to find [tex]x+10[/tex] is a factor of given function.
By remainder theorem
[tex]x+10=0[/tex]
[tex]x=-10[/tex]
Substitute x=-10
Then , we get
[tex]f(-10)=(-10)^3-75(-10)+250[/tex]
[tex]f(-10)=-1000+750+250=0[/tex]
Remainder=f(-10)=0
It means x+10 is factor of given function f(x) because when x+10 divides the f(x) then we get remainder=0.
Answer:yes, When the function [tex]f(x)=x^3-75x+250[/tex] is divided by x+10 , the remainder is zero.Therefore, x+10 is a factor of [tex]f(x)=x^3-75x+250[/tex]
