Which shows the following expression using positive exponents? a^3 b^-2/ ab^-4

Answers

Answer 1

The answer to this question would be: a^2 b^2
In this question, you have two variable ( a and b) with some exponent. To make the number express positive exponent, you can switch it location from denominator to numerator position, or vice versa. In this case, the calculation would be:

a^3 * b^-2 / a^1 b^-4=
a^3 * b^4 / a^1 b^2=
(a^3 / a^1) * (b^4/b^2)=
a^(3-1) * b^(4 -2)=
a^2 * b^ 2

solve the proportion 3x/10=9/4

Answers

x =7.5
this is because you would cross multiply to get 12x=90. You would have to isolate the variable by dividing both sides by 12. that leaves you with x=7.5

Hello There!

First solve the numerical side:
9/4 = 2.25
So now we know:
3x/10 = 2.25
Multiply both sides by 10:
3x/10 x 10 = 2.25 x 10
Simplify it:
3x = 22.5
Divide both sides by 3:
3x/3 = 22.5/3
Simplify it:
x = 7.5

3(7.5)/10 = 9/4

What is the answer to 46.25 divide by 5 - 2

Answers

First, we divide 46.25 by 5 which is 9.25. Subtract 2 from 9.25 and you have 7.25

If it's 46.25 ÷ (5-2), then the answer is 15.42

If it's (46.25 ÷ 5) - 2, then the answer is 7.25

solve the system of equation 2x-9y=14 x=-6y+7

Answers

You know the value of x: -6y +7
So you can replace the x in the first equation:
2*(-6y+7)-9y = 14
distributive law
-12y+14-9y = 14
-21y+14=14
-14
-21y = 0
:(-21)
y = 0
Now you replace the y in the seccond equation with 0
x = -6*0+7
x = 7

ANSWER: x is 7 and y is 0

To solve such problems we must know about the system of equations.

The system of the equation will give a unique solution at point (7, 0).

Given to us2x - 9y = 14x= - 6y + 7

SolutionEquation 1

2x-9y=14

as the value of x is already given in equation2, therefore, substituting the value of x in equation 1, we get,

[tex]2(6y+7)-9y=14[/tex]

[tex]-12y+14-9y=14\\ -12y-9y =14-14\\ -21y = 0\\ y =0[/tex]

Equation 2

[tex]x= - 6y + 7[/tex]

Substituting the value of y,

[tex]x= - 6(0) + 7\\ x= 7[/tex]

Verification

The system will give a unique solution at points x=7, and y=0, this can be verified by plotting the two equations on the graph.

Hence, the system of the equation will give a unique solution at point (7, 0).

a pizza with a diameter of 8 inches cost $10 a pizza with a diameter of 14 inches costs $16 whitch is the better buy explain you thinking

Answers

The 14-inch diameter pizza, because you're getting approximately 10 square inches of pizza per dollar. For the 8-inch pizza, you only get around 5 per dollar.

Final answer:

To find the better buy between the two pizzas, we calculate the cost per square inch for each. After determining the area of each pizza, the calculations show that the 14-inch pizza offers the better value at $0.104 per square inch, compared to the 8-inch pizza's $0.199 per square inch.

Explanation:

To determine which pizza offers the better buy, we need to calculate the price per square inch of each pizza. First, we find the area of each pizza using the formula for the area of a circle, A = πr^2, where r is the radius (half the diameter).

For the 8-inch pizza: radius = 4 inches. So, A = 3.14 × (4)^2 = 50.24 square inches.

For the 14-inch pizza: radius = 7 inches. So, A = 3.14 × (7)^2 = 153.86 square inches.

Next, we calculate the cost per square inch:

8-inch pizza: $10 / 50.24 square inches = $0.199 per square inch.

14-inch pizza: $16 / 153.86 square inches = $0.104 per square inch.

Therefore, the 14-inch pizza offers the better value at approximately $0.104 per square inch, as opposed to the 8-inch pizza's $0.199 per square inch.

A seal dove 95 meters below the surface of the water to reach a fish. It traveled 18% of the total distance every second. What was the depth of the seal after 5 seconds? (1 point)

Answers

95 ÷ 18% = 17.1
17.1 × 5 = 85.5
Therefor, your answer is 85.5 meters.
Hope is helps :)

Answer:

Depth of seal in 5 seconds = 85.5 meters

Step-by-step explanation:

Distance between a seal and fish = 95 meters below the surface of the water

It traveled 18% of the total distance every second so distance covered in one second = 18% of 95

= 95×0.18

= 17.10 meters

And distance covered in 5 seconds will be = 17.10 × 5 = 85.50 meters

Therefore, depth of the seal in 5 seconds will be 85.5 meters

Someone came into a store and stole 100 dollars from the register. The person returned 5 minutes later and purchased 70 dollars in merchandise with the same 100 dollars he stole I gave him 30 dollars change. How much money did the store loose.

Answers

Think of it this way. Ignore for now that $100 was stolen.

The purchase of the $70 item for $100 cash with $30 change is a perfectly fair purchase. The store received $100 cash, and the store gave $70 worth of merchandise plus $30 cash.There was no loss to the store there.

The fact that $100 in cash was stolen earlier from cash register means the loss is $100. The legitimate transaction does not affect the loss.

If you have a hard time understanding the loss is $100, then think of it this way.
Reverse the order of the two happenings.

A person walked into a store and bought a $70 item with a $100 bill. He received $30 change. So far, there is no loss to the store. Everything is legit.

That customer later came back to the store and stole $100 from the cash register.

Here we see clearly that the loss is exactly $100. It is simply the $100 stolen from the cash register.

(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.

Answers

let Kim's sisters age be x
then Kim's age= 2x
so when adding both ages you get 36
2x+x=36 i. e 3x=36 (x rep Kim's sisters age)

so x=36/3 = 12
kim sister's age is 12 years
while kim is 2×12= 24years

So because Kim's age is twice the age of her sister an appropriate ratio could be
Kim : Sister 2 : 1
So because you know thier ages are combined to 36 you could divide 36 by 3 which is 12 then you would need to double it for Kim.
So their ages are
Kim- 24
sister- 12

Angle 1 = 75 degrees.
Angle 2 = 75 degrees Angle 3 = 150 Angle 4 = 90

a bouquet had 10 flowers and sold for $90 how much would a bouqet of 5 flowers cost?

Answers

First, you would need to figure out how much a single flower would cost. To do this, you would divide $90 among the 10 flowers.
$90 ÷ 10 = $9

A single flower would cost $9.

Now, all you would have to do is multiply the cost per flower by the number of flowers.
$9 × 5 = $45

I would cost $45 for a bouquet of 5 flowers.

How many more barrels of gasoline then diesel were produced last year gasoline 34% diesel 29% total crude oil -60 million barrels Total

Answers

Answer: 3 million barrels

Step-by-step explanation:

Given :- Total crude oil= 60 million barrels

Quantity of gasoline = 34% of total crude oil

[tex]=0.34\times60\text{ million barrels}\\=20.4\text{ million barrels}[/tex]

Quantity of diesel = 29% of total crude oil

[tex]=0.29\times60\text{ million barrels}\\=17.4\text{ million barrels}[/tex]

Clearly, Quantity of gasoline is more than Quantity of diesel

difference = Quantity of gasoline-Quantity of diesel

[tex]20.4\text{ million barrels}-17.4\text{ million barrels}\\=3\text{ million barrels}[/tex]

Therefore, The production of gasoline is 3 million barrels more than diesel last year.

3 million more barrels of gasoline then diesel were produced and this can be determine by using the arithmetic operations.

Given :

Gasoline is 34% of total crude oil.Diesel is 29% of total crude oil.Total crude oil = 60 million barrels.

The quantity of Gasoline = 34% of total crude oil

[tex]=\dfrac{34}{100}\times 60[/tex]

= 20.4 million barrels

The quantity of Diesel = 29% of total crude oil

[tex]=\dfrac{29}{100}\times 60[/tex]

= 17.4 million barrels

Quantity of Gasoline - Quantity of Diesel = 20.4 - 17.4 = 3 million barrels

Therefore, 3 million more barrels of gasoline then diesel were produced.
