Answer:
The Answer is B
Step-by-step explanation:
In [tex](a^{-2} * 8^{7})^{2}[/tex], each inner term has its exponent multiplied by the two on the outside. The answer is thus [tex]a^{-4}*8^{14}[/tex] or [tex]\frac{8^{14}}{a^{4}}[/tex]

Answers
Step-by-step explanation:
Question:-Order these numbers from largest at the top, to smallest at the bottom.
1.57x10^-4
4.5x10^3
1.3x10^1
987
We can see that:-
The exponent with highest power is the largest number.
Here, the largest number is
[tex]1.3 \times 10 ^3[/tex]
Next, is [tex]987[/tex]
Smaller than this, next is :-
[tex]1.3 \times 10^1[/tex]
A number with negative power is smaller.
So, last is
[tex]1.57 \times 10^{-4}[/tex]

A school nurse can give 25 eyes test in a two-hour period. How long will it atke the nurse to give eye test to all 600 student sin her school?
Answers
Answer:
96 hours
Step-by-step explanation:
25 eyes - 2 hours
1200 eyes* - x hours
[tex]x = \frac{2 \times 1200}{25} [/tex]
[tex]x = 96[/tex]
*each student has 2 eyes. So 600 students have 600×2=1200 eyes.
It will take the nurse 48 hours to give eye tests to all 600 students in her school.
What is Expression?An expression is combination of variables, numbers and operators.
If the nurse can give 25 eye tests in two hours, then she can give 12.5 tests in one hour (since 25 divided by 2 equals 12.5).
To give eye tests to all 600 students, the nurse will need to give 600 tests in total.
Using the rate of 12.5 tests per hour, we can set up a proportion:
12.5 tests / 1 hour = 600 tests / x hours
Apply Cross-multiplication
12.5 tests × x hours = 600 tests
Divide both sides by 12.5 tests
we get, x hours = 600 tests / 12.5 tests per hour
x hours = 48 hours
Therefore, it will take the nurse 48 hours to give eye tests to all 600 students in her school.

suppose three Riders rode a total of 260 Mi if they use a total of 18 horses and rode each horse to the same number of miles how many miles did they ride before replacing the horse
Answers
Answer:
14.3 - Not entirely sure?
Step-by-step explanation:
So you first divide 260 by 3 (the riders), and if they used a total of 18 horses together you then divide them by 3 as well. You get the answer from 260 and 3 (which would be 86) also the answer from 18 and 3 (which would be 6) and divide them together (I know, lots of dividing) and there's your answer! 14.3

Aggie is an australian exchange sudent in china, and she currenly has 14,000 yuan in her bank account. If the exchange rate changes from 1 australian dollar to 6.21 yuan to 1 australian dollar 6.37 chinese yuan, what happens to the value in australian dollars of the money in aggies bank account
Answers
Step-by-step explanation:
Amount in Aggie bank account = 14,000 yuan
Initial exchange rate:
1 Australian dollar = 6.21 yuan
Initial amount in Australian dollars will be;
x aus dollar = 14,000 yuan
cross multiply
6.21x = 14,000
x = 14,000/6.21
x = 2,254.428 australian dollars
If the exchange rate increases to 6.37 Chinese yuan, her new balance in Australian dollars will be y;
1 Australian dollar = 6.37 yuan
y Australian dollar = 14,000 yuan
cross multiply
6.37y = 14,000
x = 14,000/6.37
y = 2,197.80 Australian dollars
The change in her account balance due to increase in exchange rate is y-x
y-x = 2,197.80 - 2,254.428
y-x = -56.626 aus dollars
This negative values shows a decrease in her account balance by 56.626 aus dollars due to increase in the exchange rate.

Answers
Answer:
[tex]121=6w[/tex]
Step-by-step explanation:
Formula for perimeter of a rectangle:
[tex]P=2l+2w[/tex]
[tex]w[/tex] = width
[tex]l[/tex] = length
Since the length is twice the width,
[tex]l=2w[/tex].
So, plugging these values into the formula, as well as the given perimeter of 121 feet, we get,
[tex]121 = 2(2w)+2w[/tex]
