Answer:

some information is missing, so I looked for similar questions and found the attached image:

since each recipe requires ¹/₂ cup of butter, you are able to make 12 ÷ ¹/₂ = 24 recipes with one container of butter (assuming you have all the other ingredients).

One-half, ¹/₂, is a fraction that can also be written in decimal form as 0.5. Two times ¹/₂ is equal to 1, and similarly, twenty four times ¹/₂ is equal to 12.

Answer:

  57,001 cm², or 5.7 square meters

Step-by-step explanation:

The surface area of a cylinder is given by the formula ...

  A = 2πr(r +h)

  A = 2π(14 cm)(14 cm +40 cm) = 1512π cm²

Then 12 cylinders will have an area of ...

  12 × 1512π cm² = 18,144π cm² ≈ 57,001 cm²

Rui Feng wants to paint a total surface area of 57,001 cm², about 5.7 square meters.

Answer:

10

Step-by-step explanation:

If Sabrina is 5 & Michael is 7. (5×7=35)

Michael is 7, & he is 3 yrs younger than Meghan, who is 10. And Meghan is twice as old as Sabrina, when Sabrina is 5 (5×2=10).

Answer:

Meghan is 10 years old

Step-by-step explanation:

We can write out the information with equations and then combine the information. Then, we can solve for x and hence solve for Meghan's age.

We write our first variable, x. Meghan (m) is twice as old as Sabrina (x). So we write:

m = 2x

Michael (M) is 3 years younger than Meghan. So we write:

M = m - 3

The product (multiplication) of Sabrina's and Michael's age is 35. So we write:

Mx = 35

To solve for x, we can substitute Meghan's age (2x) into the equation for Michael.

M = 2x - 3

Then, we can substitute this for M in the final equation to solve for x. This will be a quadratic so we factorise to solve it:

x(2x - 3) = 35

2x² - 3x = 35

2x² - 3x -35 = 0

(2x - 7)(x - 5) = 0

x = ⁷⁄₂ or 5

we know it is 5 since ⁷⁄₂ does not work and it is not a whole number. Hence:

m = 2(5)

m = 10

Answer:

0.75 or 3/4

Step-by-step explanation:

10 1/2 teaspoons of sugar ÷ 14 oz energy drink = ?

10.5 teaspoons of sugar ÷ 14 oz energy drink = 0.75 teaspoons of sugar per drink

OR (fraction way):

10 1/2 ÷ 14 = ?

First, Convert any mixed numbers to fractions.  Then your initial equation becomes:

21/2 ÷ 14/1 = ?

Apply the fractions formula for division (just flip the second fraction and multiply):

21/2 x 1/14 = 21/28 = 3/4 = 0.75

Answer:

[tex]1 \dfrac{1}{4} \ liters[/tex]

Step-by-step explanation:

Given that:

Claire uses 2 liters of paint to cover 1 3/5 doors

Then in order for her to paint 1 door, She will need:

2 L = 1 3/5 door

x L = 1 door

[tex]x (L) = \dfrac{2 L \times 1 door }{ 1 \dfrac{3}{5} \ door}[/tex]

[tex]x (L) = \dfrac{2 L }{ 1 \dfrac{3}{5} }[/tex]

[tex]x (L) = \dfrac{2 L }{ \dfrac{8}{5} }[/tex]

[tex]x (L) = \dfrac{2 L\times 5 }{ 8 }[/tex]

[tex]x (L) = \dfrac{10 \ L }{ 8 }[/tex]

[tex]x(L) =1 \dfrac{1}{4} \ L[/tex]

Step-by-step explanation:

[tex] \because \angle 1 [/tex] and [tex] \angle 2 [/tex] are complementary.

[tex] \therefore m\angle 1+m\angle 2=90\degree... (1)[/tex]

[tex] \because \angle 2 [/tex] and [tex] \angle 3 [/tex] are complementary.

[tex] \therefore m\angle 2+m\angle 3=90\degree... (2)[/tex]

From equations (1) & (2), we find:

[tex] m\angle 1+m\angle 2-m\angle 2=m\angle 3

Answer:

25 and 11

Step-by-step explanation:

because subtract 14 from 36 it will give u 11 so 11 is your smaller number and 25 is your bigger

Hope this helps :)

Answer:

The numbers are 11 and 25.

Step-by-step explanation:

Assign x to the the numbers.

One of the numbers is 14 more than the other.

x + (x+14) = 36

Smaller number = x

Bigger number = x +14

2x + 14 = 36

2x = 22

x = 11 = smaller number

x = 11 + 14 = 25 = bigger number

Answer:

First term = 160

Common ratio = 3/2

Step-by-step explanation:

The 3rd term and the 6th term of a G.P are 360 and 1215

The terms are 3 terms apart so find the cube root of the ratio between the 6th and the 3rd term as;

[tex]\frac{1215}{360} =\frac{27}{8} \\\\\sqrt[3]{\frac{27}{8} } =\frac{3}{2} \\\\\\=\frac{3}{2}[/tex]

The common ratio is : 3/2

To find the first term, divide the third term by the common ratio to get the second term then do that to the second term to get the first term

360 / 3/2

360 *2/3 = 240  -----2nd term

240/ 3/2

240 * 2/3 = 160 ------1st term

Answer:

[tex]f^\prime(x)=-2|x-1|-3[/tex]

Step-by-step explanation:

Write the equation for f(x)=IxI but vertically stretch it by a factor of 2, flip it over the x axis, shift it down 3 units, shift it 1 unit to the right

We have the (parent absolute value) function:

[tex]f(x)=|x|[/tex]

And we want to write a new function which represents the previous function: 1) Vertically stretched by a factor of 2, 2) flipped over the x-axis, 3) shifted down 3 units, and 4) shifted 1 unit to the right.

1)

To vertically stretch/compress a function, we multiply the function by a constant a.

We want to vertically stretch our function by 2. So, we will multiply our function by 2. Therefore:

[tex]f^\prime(x)=2|x|[/tex]

2)

We want to flip the function over the x-axis.

To flip a function over either axis:

Since we want to flip our function over the x-axis, we will multiply it by -1. So:

[tex]f^\prime(x)=-2|x|[/tex]

3)

We want to shift our function down by 3 units.

To shift a function vertically, we simply add the vertical shift to our function.

Since we are shifting downwards by 3 units, we will add -3 to our function. So:

[tex]f^\prime(x)=-2|x|-3[/tex]

4)

Finally, we want to shift our function 1 unit to the right.

To shift a function horizontally, we replace the x with (x-n), where n is the horizontal shift.

Since we are shifting our function to the right, n=1. Therefore, we will replace x with (x-1). So, our function becomes:

[tex]f^\prime(x)=-2|x-1|-3[/tex]

And we have our final function.

Note: In general, try doing the vertical/horizontal stretches first, x/y-axis reflections second, and then vertical/horizontal shifts last to avoid mistakes.

Attached above is the answer

Answer:

[tex]\huge\boxed{m\angle 1 = 131 \textdegree}[/tex]

[tex]\huge\boxed{m\angle 2 = 49 \textdegree}[/tex]

[tex]\huge\boxed{m\angle 3 = 112 \textdegree}[/tex]

Step-by-step explanation:

We can use basic angle relationships to find the measure of angles 1, 2, and 3 here.

First off, we know that the 49° angle and m∠1 are supplementary. This means that their angle measures will add up to 180°.

Since we know one, we can find the other easily.

[tex]x + 49 = 180\\\\x = 180-49\\\\x = 131[/tex]

So m∠1 = 131°.

We also know that m∠2 is opposite to the 49° angle. This means that m∠2 is also 49°.

Now, we know that m∠3 is also opposite to the 112° angle. Therefore, their angle measures are the same, and m∠3 is also 112°.

Answer:

B. $0.88

Step-by-step explanation:

x = number of bananas

y = cost of bananas in dollars

Given that 4 bananas cost $3.52, the constant of proportionality that relates cost of bananas, y, to the number of pounds of bananas, x = y/x

y = 3.52

x = 4

Therefore:

Constant of proportionality = [tex] \frac{3.52}{4} = 0.88 [/tex].
