Answer:
260 miles
Step-by-step explanation:
Sara made it to her destination in four hours, while Holly made it to her destination traveling 260 miles. This can be calculated by taking Sara's 200 miles, and dividing it by 50 mph to get a total of four hours spent driving. If Holly is also driving for four hours, but instead traveling at 65 mph, you can take 65 and multiply it by four hours to get a total of 260 miles. Hope this helps!

An item is regularly priced at $15. Raina bought it at a discount of 65% off the regular price. How much did she pay
Answer:
She paid $5.25
Step-by-step explanation:
You would multiply 15 times 0.65 and then subtract that from 15 or you could multiply 15 times 0.35 because 100-65 is 35.

Answer:

Step-by-step explanation:
given the equation y=23x,whats the value of x if y=100
Answer: 4.3478 or 100/23
Step-by-step explanation:
Set the y values equal to each other since they are the same unknown (x). You end up with 100=23x, solve for x. Move the 23 over to the other side by using division. x=100/23. If you need it in decimal form, 100÷23=4.347826087
Answer:
4.3=x
Step-by-step explanation: y=23x
substitute the variable y to 100. Now the equation looks like this 100=23x. Your next step is to get get x by itself, so you would divide 23 on both sides. That would cancel out the 23 x. The only thing you have to do now is 100 divided by 23 and that would be 4.3 and a whole bunch of number so you just round it to the nearest tenth. You answer would be 4.3.

At a fast food restaurant, customers are asked if they want to “round up” their bill to the next highest dollar and donate the additional money to charity. The cashier is instructed to tell the customer that their bill is X dollars and Y cents. Assume that the values of Y are equally likely to be any value from 0 to 99 cents and that customers are equally likely to “round up” regardless of the amount of their bill. The density curve below models Y, the donation amount. (a) What is the shape of the distribution of donations? (b) What proportion of donations are at least 85 cents? (c) What percent of donations are between 30 and 40 cents?
Answer:
(a) 0.1414
(b) 0.1010
Step-by-step explanation:
(a)
The density curve is rectangular in shape.
This implies that the distribution of donations is Uniform.
(b)
Compute the probability of donations at least 85 cents as follows:
[tex]P(X\geq 85)=\int\limits^{99}_{85} {\frac{1}{99-0} \, dx[/tex]
[tex]=\frac{1}{99}\times [x]^{99}_{85}\\\\=\frac{99-85}{99}\\\\=0.1414\\\\[/tex]
Thus, the proportion of donations that are at least 85 cents is 0.1414.
(b)
Compute the probability of donations between 30 and 40 cents as follows:
[tex]P(30\leq X\leq 40)=\int\limits^{40}_{30} {\frac{1}{99-0}} \, dx[/tex]
[tex]=\frac{1}{99}\times [x]^{40}_{30}\\\\=\frac{40-30}{99}\\\\=0.1010[/tex]
Thus, the probability of donations between 30 and 40 cents is 0.1010.

Step-by-step explanation:
Radius of the circle is r = 6/2 = 3
Area of the circle is A = π x 3^2 = 9π = 28.26
Area of the square = 6^2 = 36
Remaining board area = 36 - 28.26 = 7.74

Josh practices free throws during basketball practice on Monday and Tuesday, On Monday, he attempts 15 free throws and 6 basketballs
went in the basket. Over both days, Josh wants at least 80% of his balls to go in the basket. If he makes every free throw on Tuesday,
what is the minimum number of free throws required on Tuesday to reach his goal?
Answer:
30
Step-by-step explanation:
For the minimum free throws, he must put every throw to the basket.
So, let n be the number of throws for Tuesday, in which all the throws are successful.
So, over both the days, total free throws he makes= 15+n.
Total numbers of throws that went in the basket= 6+n.
As he wants at least 80% of his balls to go in the basket.
So, 6+n is greater than or equal to 809% of 15+n, i.e
[tex]6+n\geq \frac{80}{100}\times (15+n)[/tex]
[tex]\Rightarrow 30+5n\geq 60+4n[/tex]
[tex]\Rightarrow n\geq 30.[/tex]
Hence, the minimum number of free throws required on Tuesday to reach his goal is 30.

Factor the expression given below. Write each factor as a polynomial in
descending order. Enter exponents using the caret (^).
125x^3+343y^3
Answer:
(5x + 7y)(25x² - 35xy + 49y²)
Step-by-step explanation:
125x³ + 343y³ ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b³) , thus
125x³ + 243y³
= (5x)³ + (7y)³
= (5x + 7y)((5x)² - 5x(7y) + (7y)² )
= (5x + 7y)(25x² - 35xy + 49y²)
