If 5=a^x, then 5/a=?
Answer:
Step-by-step explanation:
To find the expression for 5/a, you first need to solve the equation 5=a^x for a. To solve for a, raise both sides of the equation to the 1/x power.
5=a^x
5^(1/x)=(a^x)^(1/x) (now multipy exponents)
5^(1/x)=a (x*1/x = 1 - the exponent on a)
Now that the equation is solved for a, substitute the left side of the equation into 5/a. So,
5/a = 5/5^(1/x) (since the bases are the same, 5, subtract the exponents; note that the exponent in the numerator = 1)
5/a = 5^(1 - 1/x) (subtract by getting lcd, x)
5/a = 5^((x-1)/x)
Just to show you that this works: Let a = 25 and x = 1/2.
We know that 5 = a^x = 25^(1/2) = sqrt(25)=5.
Now, 5/a should equal 5/25 = 1/5, so let's plug the numbers into the new expression.
5/a = 5^((.5-1)/.5) (I'm using .5 instead of 1/2 so it's not so many parentheses.)
Lucy and Cody were playing a board game. They rolled a die 142 times. An even number was rolled 56 times. A one was rolled 21 times. A three was rolled 34 times. How many times was a five rolled? Select the correct equation to solve. A. 142 - 56 - 21 + 34 = t B. 142 - 56 - 21 - 34 = t C. 142 + (56 - 21) + 34 = t Solution:
Answer:
[tex]Five = 31[/tex]
Step-by-step explanation:
Given
[tex]Total = 142[/tex]
[tex]Even = 56[/tex]
[tex]One = 21[/tex]
[tex]Three = 34[/tex]
Required:
Number of times 5 were rolled
Even represents 2, 4 and 6.
So, we have:
[tex]Total = Even + One + Three + Five[/tex]
[tex]142 = 56 + 21 + 34 + Five[/tex]
[tex]142 = 111 + Five[/tex]
Collect Like Terms
[tex]Five = 142 - 111[/tex]
[tex]Five = 31[/tex]

price
========================================================
There are two methods to get the answer.
The slightly longer method is to take 7% of the original price to get
7% of 1350 = (7/100)*1350 = 0.07*1350 = 94.50
The sales tax is $94.50
Add this onto the original price to get 1,350+94.50 = 1,444.50
----------------------------
A shortcut is to multiply the original price by 1.07
The multiplier 1.07 represents a 7% increase since
1 = 100%0.07 = 7%1.07 = 1 + 0.7 = 100% + 7%So we will have 1.07*1350 = 1,444.50
Answer:
$172.5
Step-by-step explanation:
Store A is defintley better because 6% of sales tax is $72 and $1200 + $71 = $1272 while store B: 7% of $1350 is $94.5 and $1350 + $94.5 = $1444.5. To find out how much you would save by using store A, you would simply subtract it = $1444.50 - $1272 = $172.5

Celia put hot water and cold water into a bathtub. For the first two minutes she added only hot water to the tub. After two minutes, she added both hot and cold water to the bathtub.
. The hot water flows at the rate of 2.2 gallons per minute
. The cold water flows at the rate of 3.4 gallons per minute.
. Let t represent the number of minutes Celia put cold water into the bathtub
Which inequality can be used to determine the number of minutes after which the amount of cold water Celia put into the bathtub is greater than the amount of hot water she put into the bathtub?

Fill in the blank with Yes or No. Rectangle A has length 12 and width 8. Rectangle B has length 15 and width 10. Rectangle C has length 30 and width 15. 1. Is Rectangle A a scaled copy of Rectangle B? 2. Is Rectangle B a scaled copy of Rectangle A? 3. Is Rectangle A a scaled copy of Rectangle C?
Answer:
1. Yes
2. Yes
3. No
Step-by-step explanation:
Given
Rectangle A:
[tex]Length = 12; Width = 8[/tex]
Rectangle B:
[tex]Length = 15; Width = 10[/tex]
Rectangle C:
[tex]Length = 30; Width = 15[/tex]
Solving (1): Is Rectangle A a scaled copy of Rectangle B?
To do this, we simply determine the ratio of the length and width of both rectangles;
i.e.
[tex]Ratio = \frac{A}{B}[/tex]
For Length:
[tex]Ratio = \frac{12}{15}[/tex]
[tex]Ratio = 0.8[/tex]
For Width:
[tex]Ratio = \frac{8}{10}[/tex]
[tex]Ratio = 0.8[/tex]
Since both ratios are the same, then this statement is true
Solving (2): Is Rectangle B a scaled copy of Rectangle A?
This is the inverse of (1) calculated above.
Since (1) is true, then (2) is also true
3. Is Rectangle A a scaled copy of Rectangle C?
To do this, we simply determine the ratio of the length and width of both rectangles;
i.e.
[tex]Ratio = \frac{A}{C}[/tex]
For Length:
[tex]Ratio = \frac{12}{30}[/tex]
[tex]Ratio = 0.4[/tex]
For Width:
[tex]Ratio = \frac{8}{15}[/tex]
[tex]Ratio = 0.53[/tex]
Since both ratios are the not same, then this statement is false
A binder at the store costs $4.87. A pack of pens at the same store costs $2.94. You pay for both the binder and pack of pens with a $20 bill
How much change do you receive?
Answer:
How much change you receive is $12.19
Step-by-step explanation:
$20 - $4.87 (price of a binder) - $2.94 (price of pack of pens) = ?
$4.87 + $2.94 = $7.81
$20 - $7.81 = $12.19

Mortar is made by mixing cement, sand and quicklime in the ration 1:2:3
a) work out the volume to make 2.1m cubed of mortar mix
Answer with step-by-step explanation:
If the ratio for the ingredients is 1:2:3, then the total would be 6. If so, we have to divide 2.1 by 6, which is 0.35. Now, you need to multiply 0.35 to the according ingredient amounts.
Cement: 1 x 0.35 = 0.35
Sand: 2 x 0.35 = 0.70
Quicklime: 3 x 0.35 = 1.05
If you add it up, you will get 2.1, which is the volume.
