3 cups of sugar and 6 cups of sugar

PLZ MARK BRAINLIEST!!!

Step-by-step explanation:

Three cups of sugar and six cups of flour are required to bake the cake, if for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.

It is the basic arithmetic operation, in which you are separating the number into some parts.

Given data:

A recipe for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.

Calculate the ratio for 1 cake

1 cup of sugar / 2 cups of flour

Calculate the sugar and flour  for 3 cake

1 cup of sugar / 2 cups of flour × 3

3 cups of sugar / 6  cups of flour

Therefore, 3 cups of sugar and 6  cups of flour are required to bake the cake if for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.

***If the image is sideways, use the rotate button.

Alternate exterior angles are congruent.

This means the angles are equal.

(14x - 1)° and 125° are alternate exterior angles.

(14x - 1)° = 125°

The value of x is 8.86°.

The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.

Corresponding angles are equal.

We have,

The diagram:

Line k is parallel to line l.

Line t intersects line k and line l.

This means that,

(14x - 1)° and 125° are alternate exterior angles.

Alternate exterior angles are congruent.

This means the angles are equal.

We get,

(14x - 1)° = 125°

14x - 1 = 125

Add 1 on both sides.

14x - 1 + 1 = 125 + 1

14x = 124

Divide both sides by 14.

x = 124/14

x = 8.86°

Thus,

(14x - 1)° and 125° are alternate exterior angles.

(14x - 1)° = 125°

The value of x is 8.86°.

Answer:

the download cost for a song is $1 and $11 for a movie

Step-by-step explanation:

According to the questions, the following equations are as follows:

Let us assume the song be x

And, the movies be y

So,

20x + 13y = $163.........(i)

13x + 13y = $156........(ii)

Now solve substract second equation from the first equation

7x = $7

x = $1

And the y value is

20 + 13y = $163

13y = $163 - $20

13y = $143

y = $11

Hence, the download cost for a song is $1 and $11 for a movie

Answer:

=−10y+11.5

Step-by-step explanation:

Let's simplify step-by-step.

3−2y−8y+8.5

=3+−2y+−8y+8.5

Combine Like Terms:

=3+−2y+−8y+8.5

=(−2y+−8y)+(3+8.5)

The probability that both erasers chosen were blue is 3/25.

To find the probability that both erasers chosen were blue, we need to determine the favorable outcomes (choosing two blue erasers) and the total possible outcomes.

There are a total of 25 erasers in the cup: 7 red erasers + 4 yellow erasers + 9 blue erasers + 5 green erasers = 25 erasers.

To calculate the probability, we consider the events of choosing a blue eraser without replacement.

For the first pick, there are 9 blue erasers out of 25 total erasers.

After the first blue eraser is chosen, there are 8 blue erasers remaining out of 24 total erasers.

The probability of choosing a blue eraser on the first pick is 9/25.

The probability of choosing a blue eraser on the second pick, without replacement, is 8/24.

To find the probability of both events occurring (both erasers chosen being blue), we multiply the probabilities together:

(9/25) * (8/24) = 72/600 = 6/50 = 3/25

Therefore, the probability that both erasers chosen were blue is 3/25.

Answer:

$25.96

Step-by-step explanation:

So Shawna's manicure was $22 dollars, and she left and 18% tip. In other words, she added 18%, or 0.18 to the total original price. We can represent this with an expression:

[tex]1.18 * 22[/tex]

As she pays 100%, or 1, plus another 18%, or 0.18 to the original price of $22.

Thus her total amount was $25.96

Hope this helps!

Answer:

She paid $25.96 in total

Step-by-step explanation:

The tip was $3.96. When you convert the 18% to a decimal you get .18 then, you multiply the .18 to the $22 (22x .18= 3.96). Finally, you add how much the manicure was to the tip (22+3.96=25.96)

Answer:

i. Girls : 10 merits

ii. Boys : 11.4 merits

iii. The boys did better on average because the number of their mean merits received is higher than that girls.

Step-by-step explanation:

Mean = [tex]\frac{sum of merits}{number of merits}[/tex]

Sum of merits received by boys = 5 + 10 + 19 + 22 + 13 + 10 + 1

                                    = 80

number of merits = 7

Mean number of merits received by boys = [tex]\frac{80}{7}[/tex]

                                           = 11.4286

The mean number of merits received by boys is 11.4

Sum of merits received by girls = 6 + 11 + 15 + 16 + 12 + 10 + 0

                                                 = 70

number of merits = 7

Mean number of merits received by girls = [tex]\frac{70}{7}[/tex]

                                             = 10.0

The mean number of merits received by girls is 10.0

Therefore,

i. Girls : 10 merits

ii. Boys : 11.4 merits

iii. The boys did better on average because their mean merits is higher than that girls.

Step-by-step explanation:

after 4 hours, the water level decreased by 8 feet

which is -8

Therefore -8/4 = -2 change in water level every hour

Answer:

The constant rate of change is 2 feet every hour.

Step-by-step explanation:

Since the level of the water was at 10 feet at 2 pm, and the water at 6 pm was at 2 feet, the water level dropped 8 feet in 4 hours.

With this information we can create the ratio 4:8 and when you simplify the ratio down to 1, you get 1:2

1 Representing 1 hour

2 Representing 2 feet

Every hour, the water level drops 2 feet.
