Answer:

The ratio of sanstone to marble is... 141414 : 333

All you have to do is look at how much sandstone Dean has and how much marble he has, then put the amount of sandstone infront of the amount of marble because in the question it says what is the ratio of sandstone to marble and you see that sandstone is first.

Hope this helps! :)

Length X Width = area

Answer:

The area of the new rectangle is 384 square units.

Step-by-step explanation:

For the original rectangle, the length is 8, and the width is 12. For the scale copy, the width is 24 (12 × 2), so the length will be 16 (8 × 2). Multiplying 24 by 16, we obtain 384 as the area of the new rectangle.

Answer:

◘ 12 pears

◘ 3 pineapples

◘ 10 kiwis

Step-by-step explanation:

Let \(x\) be the number of pears bought.

Therefore:

• number of pears = \(x\)

• number of pineapples = \(x - 9\)

• number of kiwis = \(x - 2\)

We know that the total cost was $13.50.

This means if she bought \(x\) pears at $0.50 each, \((x - 9)\) pineapples at $1.50 each, and \((x -2)\) kiwis at $0.30 each, the total would be $13.50.

∴  \([x \times 0.50] + [(x-9) \times 1.5] + [(x-2) \times 0.3] = 13.50\)

Expanding and multiplying:

⇒ \(0.5 x + 1.5x - 13.5 + 0.3x - 0.6 = 13.5\)

Collect like terms:

⇒ \(2.3x -14.1 = 13.5\)

Solve for \(x\):

⇒ \(2.3x = 13.5 + 14.1\)

⇒ \(2.3 x = 27.6\)

⇒ \(x = 27.6 \div 2.3\)

⇒ \(x = \bf 12\)

Therefore, she bought:

• 12 pears

•  \(x - 9\) = 12 - 9 = 3 pineapples

• \(x - 2\) = 12 - 2 = 10 kiwis

Marita bought 12 pears, 3 pineapples and 10 kiwis.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Let x the number of pears bought,

y the number of pineapples bought,

z the number of kiwis bought,

Given that, Marita bought 9 more pears than pineapples and 2 fewer kiwis than pears,

y + 9 = x

y = x -9 and

z + 2 = x

z = x - 2

We know that the total cost was $13.50.

This means if she bought  pears at $0.50 each,  pineapples at $1.50 each, and  kiwis at $0.30 each, the total would be $13.50.

∴  0.50x + 1.50y+ 0.30z = 13.50

Substitute the values of y and z in equation,

⇒ 0.50x + 1.50(x -9)+ 0.30(x - 2) = 13.50

Expanding and multiplying terms in equation,

⇒  0.50x + 1.50x -13.50+ 0.30x - 0.60 = 13.50

Rearrange the like terms and apply the arithmetic operation

⇒ 2.3x - 14.1 = 13.50

⇒ 2.3x = 13.50 + 14.1

⇒ 2.3x = 27.6

⇒ x = 27.6/2.3

⇒ x = 12

Therefore, the number of pears bought = 12

So, the number of pineapples bought = 12 - 9 = 3

And the number of kiwis bought = = 12 - 2 = 10

Hence, Marita bought 12 pears, 3 pineapples and 10 kiwis.

Answer:

D

Step-by-step explanation:

Lets go through each answer choice and check if it is correct.

A: False. 50% of 70 is not 31.

B: False. 17% of 70 is not 17.

C: False. The fraction 8/70 does not simplify to 2/25.

D: Correct. The fraction 14/70 simplifies to 2/10.

Answer:

The answer is D, On average, 2 out of 10 adults visited the museum most frequently.

Step-by-step explanation:

You can find this out by finding out how many adults there was total. You would do 31+14+17+8=70 and the you can see that 14 went to the museum so it would be 14/70. This fraction simplifies to 2/10.

Therefore,the possible length of the dog run is 80 feet

Hence, 750 is the number.

Answer:  36 is a multiple of 12

2 is a prime number.

2 is a factor of 64

Step-by-step explanation:

12 × 3 =36, so 12 is one of the factors.

2 is the only even prime number. All other even numbers are multiples of 2.

9 is not a prime number. 3 × 3 = 9

2 is a factor of 64.  2 × 32 = 64  None of the other numbers given can divide evenly into 64, so they are not factors of 64.

Answer:36 is a multiple of 12

Step-by-step explanation:

Here's the question for the answer

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.
