Answer:

Step-by-step explanation:

3.8×10^{-5}:8.1×10^3

[tex]\frac{3.8 \times 10^{-5}}{8.1 \times 10^3} \\\approx4.69 \times 10^{-9}[/tex]

Performing this mathematical operation in scientific notation gives us the answer 4.691 x 10^-8.

To solve this mathematical problem, we will first divide the coefficients and then subtract the exponents of the 10s, because we are dividing. The operation 3.8 ÷ 8.1 equals approximately 0.4691. However, we have to express the coefficient in scientific notation, so we adjust it to 4.691. At the same time, we adjust the exponent by adding 1 to it, to account for the fact that we moved the decimal one place. The operation -5 - 3 equals -8. So, the final answer is [tex]4.691 \times 10^-8.[/tex]

Answer:

  b. x(x +4)

Step-by-step explanation:

The perimeter is 4 times the length of one side, so is ...

  P = 4(x +4)

The area is the square of the length of one side, so is ...

  A = (x +4)(x +4)

The difference in these values is ...

  A - P = (x +4)(x +4) - 4(x +4)

The latter factor can be factored out to give ...

  A - P = (x +4 -4)(x +4)

  A - P = x(x +4) . . . matches B

Answer:

He saw 9 movies :0

Step-by-step explanation:

First, you take the total cost and subtract the one time cost from it ($68 - $14 = $54) Next, you take the $54 and divide it buy the cost of dollars per movie. ($54/$6 = 9)

So, 9 is your answer.

Hope this helps!!

Final answer:

To find the number of movies Fern saw, subtract the cost of the discount movie pass from the total amount she spent and then divide the result by the cost of each movie ticket. Fern saw 9 movies.

Explanation:

To find the number of movies Fern saw, we need to subtract the cost of the discount movie pass from the total amount she spent and then divide the result by the cost of each movie ticket.

The cost of the discount movie pass is $14, and Fern spent a total of $68. So, $68 - $14 = $54 is the amount she spent on movie tickets.

Since each movie ticket costs $6, we divide the amount she spent on movie tickets by the cost of each movie ticket: $54 ÷ $6 = 9.

Therefore, Fern saw 9 movies.

Answer:

136 Inches

Step-by-step explanation:

One side will be x. The other will be 3x.

x=17

3x=51

It is asking for 8x

8x=136

Answer:

136 inches

Step-by-step explanation:

The perimeter of a rectangle can be found using:

p=l+l+w+w

We know the width is 17, and the length is 3 times the width, which is 17

p=(17*3)+(17*3)+17+17

p=51+51+17+17

p=136

So, the perimeter is 136 inches

Answer: 4.50 + p

Step-by-step explanation: For this problem we will write and simplify an expression to represent how much more Elana spent.

8.75 + 5p - (4.25 + 4p)        ---Distribute the negative sign to the numbers inside the parentheses.

8.75 + 5p - 4.25 - 4p            ---Combine like terms

8.75 - 4.25 + 5p - 4p

4.50 + p

So, the expression 4.50 + p represents how much more Elana spent.

Final answer:

Elana spent $4.50 plus the price of 1 pound of cherries more than Taniy. The expression representing this difference is simplified to $4.50 + p.

Explanation:

To find out how much more Elana spent than Taniy, we'll write an expression representing the total amount each person spent, using p as the variable for the price per pound of cherries. Elana's total spending is the cost of the watermelon plus the cost of cherries, expressed as 8.75 + 5p. Taniy's total spending is the cost of the pineapple plus the cost of cherries, expressed as 4.25 + 4p. To find the difference in their spending, we subtract Taniy's total from Elana's total.

The expression representing how much more Elana spent is:

(8.75 + 5p) - (4.25 + 4p)

Now we simplify the expression:

8.75 + 5p - 4.25 - 4p which simplifies to 4.50 + p.

Therefore, Elana spent $4.50 plus 1 pound of cherries more than Taniy.

Answer:

4 Hr.

Step-by-step explanation:

Given,

Your pump alone can empties the water in = 8 hrs

With the help of friend pump it take = 2.67 hr

time taken by friends to empty the whole tank = t = ?

We have,

[tex]\dfrac{1}{8}+\dfrac{1}{t}= \dfrac{1}{2.67}[/tex]

[tex]\dfrac{1}{t}= \dfrac{1}{2.67}-\dfrac{1}{8}[/tex]

[tex]\dfrac{1}{t}=0.2499[/tex]

[tex]t = \dfrac{1}{0.2499}[/tex]

[tex]t = 4\ hrs[/tex]

Time taken to empty the tank by the friends pump alone is equal to 4 Hr.

The time taken should be 4 hours.

Since Your pump empties the water from a swimming pool in 8 hours. When your friend's pump is used together with your pump, the pool is emptied in 2 hours and 40 minutes.

So, here the time taken be

[tex]1\div 8 + 1\div t = 1\div 2.67\\\\1\div t = 1\div 2.67 - 1\div 8\\\\1\div t = 0.2499[/tex]

t = 4 hours

hence, The time taken should be 4 hours.

The value of y in the given equation equals -3.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is,

5(y + 2/5) = -13

We have to find the value of y.

Using the distributive property,

5(y + 2/5) = (5y) + (5 × 2/5)

So,

(5y) + (5 × 2/5) = -13

5y + 2 = -13

Subtracting both side by 2, we get,

5y = -13 - 2

5y = -15

Dividing both sides by 5,

y = -3

Hence the value of y is -3.

Final answer:

To solve the equation 5(y + 2/5) = -13, you distribute the 5 across the parentheses, subtract 2 from both sides, and then divide by 5 to find that y = -3.

Explanation:

To find the value of y in the equation 5(y + 2/5) = -13, we will follow several steps to isolate y. First, we apply the distributive property of multiplication over addition, which gives us 5y + 2 = -13.

Next, we subtract 2 from both sides of the equation, obtaining 5y = -15. Finally, we divide both sides of the equation by 5 to solve for y, resulting in y = -3.

Answer:

Step-by-step explanation:

A soccer ball is in the form of a Sphere.

Volume of a Sphere: V = (4/3)πr3

In this case, V = 288π cm3. So:

1) Substitute the known value into the equation: 288π = (4/3)πr3

2) Notice the π value is on either side of the equation. It cancels: 288 = (4/3)r3

3) Simplifying: r3 = 216

4) Solving for r yeilds : r = 6 cm

The radius (r) of a soccer ball with a volume of 288 cm3 is 6 cm
