Answer:
[tex]\frac{27}{8}[/tex]
Step-by-step explanation:
using the rules of exponents/ radicals
• [tex](\frac{a}{b}) ^{-m}[/tex] = [tex](\frac{b}{a}) ^{m}[/tex]
• [tex]a^{\frac{m}{n} }[/tex] = [tex](\sqrt[n]{a}) ^{n}[/tex]
then
[tex](\frac{16}{81}) ^{-\frac{3}{4} }[/tex]
= [tex](\frac{81}{16}) ^{\frac{3}{4} }[/tex]
= [tex]\frac{(\sqrt[4]{81})^3 }{(\sqrt[4]{16})^3 }[/tex]
= [tex]\frac{3^3}{2^3}[/tex]
= [tex]\frac{27}{8}[/tex]

express the following ratios as fractions in their lowest term
a.4 birr to 16 cents
b.5 days to 100 hrs
Answer:
1/4 is A and 1/20 is B
Step-by-step explanation:
Not much of an explanation needed
The ratios 4 birr to 16 cents and 5 days to 100 hrs can be expressed as [tex]\frac{1}{4}[/tex] and [tex]\frac{1}{20}[/tex] in their lowest terms.
What is Ratio?Ratio is the relationship between two quantities which shows the number of times that the one quantity is contained within the other quantity.
If 'a' is related to 'b', they can be denoted in terms of ratio as a : b.
Ratios can be expressed as fractions.
(a) 4 birr to 16 cents = [tex]\frac{4}{16}[/tex]
The highest common factor of both 4 and 16 is 4.
[tex]\frac{4}{16}[/tex] = (4 × 1) / (4 × 4) = [tex]\frac{1}{4}[/tex]
(b) 5 days to 100 hrs = [tex]\frac{5}{100}[/tex]
The highest common factor of 5 and 100 is 5.
[tex]\frac{5}{100}[/tex] = (5 × 1) / (5 × 20) = [tex]\frac{1}{20}[/tex]
Hence the ratios can be expressed as [tex]\frac{1}{4}[/tex] and [tex]\frac{1}{20}[/tex] in their lowest terms.

An aquarium holds 11.5 cubic feet of water, and is 2.2 feet long and 1.6 feet wide. What is its depth??
The depth is _____ feet.
Answer: 3.52
Step-by-step explanation:
Hey!
So for this problem, we need to follow the Volume formula which is:
length x width x height
We know our length and width so all we need is our height (depth)
First , We multiply our length and width.
2.2 x 1.6 = 3.52
Next, we figure out what times this will equal 11.5. We can see that this number can’t be times 4 because that would make it twelve so we need to lower it. We can divide 11.5 (the volume) by 3.52 to get our answer.
We get 3.267. Rounded to the hundredths it would be 3.27 ft.
Hope this helps! :D

A construction worker is making concrete by mixing sand, gravel, and cement in water. For each pound of sand, he uses 1 2/3 pounds of gravel. For each pound of gravel, he uses 2/5 pound of cement. He is making enough concrete that he needs to use 3 pounds of sand. How many pounds of cement does he use? PLEASE HELP DUE NOW !! TYYY
A. 1 pound
B. 1 4/15 pounds
C. 2 pounds
D. 2 1/15 pounds
Using mathematical operations, the construction worker requires C. 2 pounds of cement to mix 3 pounds of sand.
What are the mathematical operations?The basic mathematical operations are subtraction, addition, division, and multiplication.
These mathematical operations combine numbers, variables, mathematical operands, and the equation symbol to solve mathematical problems.
In this situation, we can apply the mathematical operation of multiplication to determine the quantity of cement required for 5 pounds of gravel.
The quantity of gravel per pound of sand = 1²/₃ = 1.667 pounds
For 3 pounds of sand, the quantity of gravel required = 5 pounds (1²/₃ x 3)
The quantity of cement per pound of gravel = ²/₅ pounds or 0.4
For 3 pounds of sand and 5 pounds of gravel, the quantity of cement required = 2 (5 x 0.4) or (5 x ²/₅)
Thus, 2 pounds of cement are needed to mix with 3 pounds of sand and 5 pounds of gravel.

how many times does 5 go into 103?
Answer and Step-by-step explanation:
We know that 5 can go into 100 twenty times, so lets try 20 and see what happens.
5 times 20 = 100
103
- 100
3
We get a remainder of 3. This means that 5 goes into 103 only Twenty times.
If we were to fully divide 103 by 5, then 5 goes into 103 '20.6' times.

Answer:
x=4, y =5
Step-by-step explanation:
there's no factorization involved, just elimination and substitution. First subtract equation 1 and 2. The x's cancel out and you get y by itself and can solve for it. Then plug the value of y into equation 2 and solve for x and you get it. (In my picture I put value of y in equation 1 but your question asks for putting it in equation 2 so do that instead)
A spinner has regions numbered 1 through 18. What is the probability that ___________________
the spinner, spun once, will stop on an even number or a multiple of 3?
Answer:
Probability that the spinner stop on an even number or a multiple of 3 = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Given - A spinner has regions numbered 1 through 18.
To find - What is the probability that the spinner, spun once, will stop on an even number or a multiple of 3?
Solution -
Given that,
A spinner has regions numbered 1 through 18.
So,
The sample space, S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18}
i.e.
n(S) = 18
Now,
Let A be the outcomes that gives even number or a multiple of 3,
Then
A = {2, 3, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18}
i.e.
n(A) = 12
∴ we get
Probability that the spinner stop on an even number or a multiple of 3 = [tex]\frac{n(A)}{n(S)}[/tex]
= [tex]\frac{12}{18}[/tex]
= [tex]\frac{2}{3}[/tex]
i.e.
Probability that the spinner stop on an even number or a multiple of 3 = [tex]\frac{2}{3}[/tex]

Alan has 11 nickels and
dimes in his pocket. When
he counted his change he
found he had $0.95. How
many dimes does Alan
have?
Answer:
4
Step-by-step explanation:
Nickels are 5 cents a piece so you will multiple 11 by 5 to find how much Alan has in nickels. Then subtract that from the total of 95 to get your answer.
11 × 5 = 55
95 - 54 = 40
Since dimes are worth 10 cents you divide 40 by 10 and that is how many dimes Alan has.
40/10=4

Write the equation of a line in slope-intercept form that has a slope of -5 and passes through the point (3,- 2)
9514 1404 393
Answer:
y = -5x +13
Step-by-step explanation:
We know from the slope-intercept equation ...
y = mx + b
that the y-intercept b can be found as ...
b = y - mx
Filling in the given values of m and (x, y), we find ...
b = -2 -(-5)(3) = 13
Then the equation is ...
y = -5x +13
