Clarissa has a sink that is shaped like a half-sphere. The sink has a value of 660tt in^3. One day her sink clogged, she has to use one conical cup to scoop the water out of the sink. The sink is completely full when Clarissa begins scooping.
(a) The conical cup (shaped like a cone) has a diameter of 5 in and a height of 8 in. How many cups of water must Clarissa scoop out of the sink with this cup to empty it?
(ROUND THE NUMBER OF SCOOPS TO THE NEAREST WHOLE NUMBER)
Answers
Answer:
13 scoops
Step-by-step explanation:
PART 1) 2.5*2.5*8/3*3.14
52.36
PART 2) 660/52.36
13 scoops
Answer:
40 scoops
Step-by-step explanation:
Volume of the sink is 660pi in³
Volume of the cone/scoop is:
⅓ × pi × 2.5² × 8 = 50pi/3 in³
No. of scoops required:
660pi ÷ 50pi/3
660 ÷ 50/3 = 39.6

Can you help me on this math problem pleaseee?
Answers
Answer:
a. - 1 3/4
b. 6
Step-by-step explanation:
For each, plug in the given number to the corresponding variable:
a. When x = -2. Plug in -2 for x in the given expression:
2^(-2) - 2
Simplify. Note that when a negative sign is located in the power sign, you would do the normal power, and then put the number over 1.
2^(-2) = 1/(2 x 2) = 1/4
Simplify:
1/4 - 2 = - 1 3/4
- 1 3/4, or -7/4 is your answer.
b. When x = 3. Plug in 3 for x in the given expression:
2^(3) - 2
Simplify. First solve the power, then subtract:
2^3 = 2 * 2 * 2 = 4 * 2 = 8
8 - 2 = 6
6 is your answer.

Josie and her brother, Sean both have a job after school. For every $5.50 José earns, her brother earns $6.50. On Tuesday, they earned a total of $30.00. How much did Josie earn? How much did her brother earn?
Answers
5.50h + 6.50h = 30.00
Whereas 'h' stands for number of hours worked.
Simplify the equation:
12h = 30.00
Divide:
h = 30.00/12
Simplify;
h = 5.00/2
h = 2.50
They worked for 2.5 hours. Now that we know how many hours they worked, simplify multiply the number of hours by their pay rate:
Josie: 5.50 * 2.5 = $13.75
Sean: 6.50 * 2.5 = $16.25

Me. Sanchez bought some books at a book sale, including 15 paperback books. 75% of all the books he bought were paperbacks
Answers
The total number of books based on the given percentage will be 20 including 15 paperback books.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Suppose Mr. Sanchez bought a total of x number of books.
75% of x = (75/100)x
This is the paperback thus,
(75/100)x = 15
x = 1500/75 = 20
Thus, the number of total books = 20 including 15 paperback books.
Hence "The total number of books based on the given percentage will be 20 including 15 paperback books".

With similar triangle, the ratios of all three paris of corresponding sides are equal
Answers
Answer:
TRUE
Step-by-step explanation:
If this is a True/False question, the answer is True.
__
One of the ways to define triangle similarity is by the ratios of the sides. If the ratios of corresponding sides are the same, the triangles are similar.
Another way to define triangle similarity is by the angle measures. If corresponding angles are congruent, the triangles are similar.
Both conditions will be met by similar triangles.

As x approaches ∞, which statement is correct?
A) The linear function will eventually exceed the exponential function.
B) The exponential function will eventually exceed the linear function.
C) The exponential function will only exceed the linear function if it has a greater growth factor.
D) The linear function will only exceed the exponential function if it has a greater common difference.
Answers
Answer:
B
Step-by-step explanation:
This is very simple if we understand a point of linear and exponential functions.
First of all, a linear growing function increases.
An exponential growing function increases as well.
But, linear function, no matter what the slope is, grows at a CONSTANT RATE. But,
Exponential function grows at a COMPOUND RATE.
So, if there are 2 functions, linear and exponential, the exponential will always exceed the linear, AT SOME POINT EVENTUALLY because of the growth factor (no matter growth factor of linear and exponential -- whatever they are).
So,
B is the correct answer.
Growth factor of each (both) doesn't matter. Exponential will always win!
Answer:
b
Step-by-step explanation:
The exponential function will always exceed the linear function.A quantity increasing exponentially eventually exceeds a quantity increasing linearly.

quarterly, to have a balance of $1000 after 10
years?
Answers
Answer:
[tex]\$487.48[/tex]
Step-by-step explanation:
we know that
The compound interest formula is equal to
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
[tex]t=10\ years\\ A=\$1,000\\ r=7.25\%=7.25/100=0.0725\\n=4[/tex]
substitute in the formula above
[tex]1,000=P(1+\frac{0.0725}{4})^{4*10}[/tex]
[tex]1,000=P(\frac{4.0725}{4})^{40}[/tex]
[tex]P=1,000/(\frac{4.0725}{4})^{40}[/tex]
[tex]P=\$487.48[/tex]

D) {-2, -1, 0, 1, 2
Answers
Hello! Remember you have to write complete questions in order to get good and exact answers. Here you forgot to write the relation so I could help you providing my own relation.
Remember that for any relation, we have a set [tex]A[/tex] that matches the the domain (also called the set of inputs) of the function and the set [tex]B[/tex] that contains the range (also called the set of outputs).
Suppose our relation is:
[tex]y=-10+x \\ \\ For \ x=1,2,3,4,5[/tex]
So the x-values represents the set A and the y-values the set B. Therefore, by evaluating the x-values into our relation we get:
[tex]\text{If x=1} \\ \\ y=-10+1=-9 \\ \\ \\ \text{If x=2} \\ \\ y=-10+2=-8 \\ \\ \\ \text{If x=3} \\ \\ y=-10+3=-7 \\ \\ \\ \text{If x=4} \\ \\ y=-10+4=-6 \\ \\ \\ \text{If x=5} \\ \\ y=-10+5=-5[/tex]
So in this context, the correct option is:

Yoryi bought an Apple Watch for $470. He paid $200 at the time of purchase and will make monthly payments of $30 to finish paying for the Apple Watch. He used the equation 200 + 30m = 470 to determine the number of months (m) he needs to make payments. For how many months will he make payments?
Answers
Answer:
9 months
Step-by-step explanation:200+30m=470
30m=270
m=9
He will pay for 9 months
Yoryi will make payments for 9 months.
Explanation:To determine the number of months (m) Yoryi needs to make payments, we can solve the equation 200 + 30m = 470. Here's how:
Subtract 200 from both sides of the equation: 30m = 270.Divide both sides of the equation by 30: m = 9.Therefore, Yoryi will make payments for 9 months.

I am 97 cm tall and my elder brother is 2m tall. How much taller is my elder brother than I?
Answers
Answer: 1.3 meters taller. so 103 cm.
Step-by-step explanation:
Answer:
103cm
Step-by-step explanation:
From the question given, we obtained the following data:
Height of the boy = 97cm
Height of the elder brother = 2m
First let us convert the height of the elder brother to cm. This is illustrated below:
1m = 100cm
2m = 2 x 100 = 200cm
So, the elder brother is 200cm tall. To know how much taller the elder brother is than the boy, subtract the height of the boy from that of the elder bother' as shown below:
200 — 97 = 103cm
Therefore, the elder brother is 103cm taller than the boy

90 in terms of pi please help
Answers
90 in terms of pi is [tex]\frac{\pi}{2}[/tex] .
Step-by-step explanation:
We know that ,
Degrees are a unit of angle measure. A full circle is divided into 360 degrees. For example, a right angle is 90 degrees. A degree has the symbol ° and so ninety degrees would written 90°. Another unit of angle measure is the radian.The radian is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics. The length of an arc of a unit circle is numerically equal to the measurement in radians of the angle that it subtends; one radian is just under 57.3 degrees.We have to convert 90 in terms of pi i.e. degree to radians:
⇒ [tex](90)\frac{\pi }{180}[/tex]
⇒ [tex]\frac{90 }{180}(\pi)[/tex]
⇒ [tex]\frac{1 }{2}(\pi)[/tex]
⇒ [tex]\frac{\pi}{2}[/tex]
Therefore, 90 in terms of pi is [tex]\frac{\pi}{2}[/tex] .
