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:

[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°.

Hope this helped!

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:

$2.58

Step-by-step explanation:

First, we should divide each number by 10 to get the amount per person we get...

10 cups

10 plates

20 balloons

Since the cost of cups, plates, and balloons is written as 100 of them, we just have to divide each of the by the amount we got after dividing by 10 and use that same amount and divide the money...

1. 10 cups is 1/10 of 100 cups so we divide $5.45 by 10 = .545

2. 10 plates is 1/10 of 100 plates so we divide $4.75 by 10 = .475

3. 20 balloons is 1/5 of 100 balloons so we divide $7.80 by 5 = 1.56

Now, we add them all up to get $2.58

Hope this Helps!!! :)

Answer:

D The volume of a cube increases by a factor of 8 when its edge length doubles

Step-by-step explanation:

Volume of a cube is represented by the function

[tex]V(x)=x^3[/tex]

where [tex]x[/tex] represents the edge length of the cube

Now when [tex]x=2x[/tex] i.e., when the edge length is doubled we have

[tex]V(2x)=(2x)^3\\\Rightarrow V(2x)=8x^3\\\Rightarrow V(2x)=8(V(x))[/tex]

It can be seen that the volume of the cube increased by 8 times when edge length doubles.

Answer:

Step-by-step explanation:

[tex]x^2 - 2x = 120\\x^2 - 2x - 120 = 0[/tex]

We have to find the factors of 120 that can either add up to or have a difference of 2.

The factors of 120 are:

[tex]\pm 1, 120, 2, 60, 3, 40, 4, 30, 5, 44, 6, 20, 8, 15, 10, 12...[/tex]

The difference of 10 and 12 is 2. In the equation, since the 2 is negative, the larger number must be subtracted, so the factorized form is:

[tex](x+10)(x-12)[/tex]

Answer:

[tex]d = 2.5r[/tex] and [tex]r = \frac{d}{2.5}[/tex]

Step-by-step explanation:

Given

5 daises to 2 roses

Required

Determine the relationship between them

The question shows a direct proportion between number of daises and roses.

i.e.

[tex]d\ \alpha\ r[/tex]

Where d = daises and r = roses

Convert the above expression to an equation

[tex]d = kr[/tex]

Make k the subject

[tex]k = \frac{d}{r}[/tex]

When d = 5 and r = 2;

[tex]k = \frac{5}{2}[/tex]

[tex]k = 2.5[/tex]

So, the first relationship between d and r can be gotten by substituting 2.5 for k in d = kr

So:

[tex]d = 2.5 * r[/tex]

[tex]d = 2.5r[/tex] ----------- (1)

Make r the subject in (1)

[tex]r = \frac{d}{2.5}[/tex] ------------------------(2)

Hence, the relationships between d and r are:

[tex]d = 2.5r[/tex] and [tex]r = \frac{d}{2.5}[/tex]

Answer:

3.5

Step-by-step explanation:

 3.5 inches would represent 350 feet.

Relationship between inches and feet is that one inch is equal to [tex]\boldsymbol{100}[/tex] feets as per the map.

So,[tex]350[/tex] feet represent [tex]\frac{350}{100}=3.5[/tex] inches.

Therefore, [tex]\boldsymbol{3.5}[/tex] inches would represent [tex]350[/tex] feet in decimal.

Answer:

Step-by-step explanation:

Step one:

given

number of blinks= 3

time taken to blink=15 seconds

the rate of blink is given as

rate= number of blinks/time taken

rate= 3/15

rate= 1/5 blinks per second, 0.2 blinks per second

Step two:

hence for a 65 second period, the number of blinks is

rate=number of blink/time

0.2=number of blink/9=65

cross multiply we have

number of blink=0.2*65

number of blink=13 blinks

Answer:

You will need to make 3 transactions

Step-by-step explanation:

For the first one you will do 22 times 3 people which is 66 plus 10 which is 76. For the second one you will do 20 times 3 people which is 60 plus the 16 dollar which gives you 76. So 3 people have to buy tickets for the two companies to have the same price.

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
