Answer:

[tex]x = 8.5[/tex] and [tex]y = 5.3[/tex]

Step-by-step explanation:

Given

[tex]x = cupcakes[/tex]

[tex]y = brownies[/tex]

From the first statement:

[tex]2.75x + 1.25y = 30[/tex]

From the second statement:

[tex]x + y \le 14[/tex]

Required

Solve graphically

I've written the equations (above) and they are:

[tex]x + y \le 14[/tex]

[tex]2.75x + 1.25y = 30[/tex]

See attachment for graph.

The blue line represents [tex]2.75x + 1.25y = 30[/tex]

The shaded part of the graph represents [tex]x + y \le 14[/tex]

From the graph, the solution is:

[tex]x = 8.5[/tex]

[tex]y = 5.3[/tex]

Answer:

= 0.8 + -0.4y

Step-by-step explanation:

Simplifying

5x + 2y = 4

Solving

5x + 2y = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

5x + 2y + -2y = 4 + -2y

Combine like terms: 2y + -2y = 0

5x + 0 = 4 + -2y

5x = 4 + -2y

Divide each side by '5'.

x = 0.8 + -0.4y

Answer: B. Acute and F. Equilateral

Step-by-step explanation: Acute triangles contain interior angles that are less than 90 degrees. All triangles must have interior angles that add to 180 degrees when combined. In this triangle, all interior angles are equal. Therefore, we can divide 180 by the 3 angles to find that each angle is 45 degrees. 45 degrees is less than 90, so it is an Acute Triangle.

In equilateral triangles, all sides have the same length. We can see in the diagram that all of the sides contain the same marking, indicating they are the same length. So, the triangle is also equilateral.

Hope this helps!

Answer:

Look below! Branliest please!

Step-by-step explanation:

To find the volume, we multiply 12 by the height and then by 3.14. So for 1, we get 1*12 which equals 12, then we multiply that by 3.14 and we get 37.68. So we do that for all of them.

1*12*3.14 = 37.68

3*12*3.14 = 113.04

5*12*3.14 = 118.4

7*12*3.14 = 263.76

Answer:

It should be 56, sorry if i am wrong

Step-by-step explanation:

28 divided by 14 is 2

56 divided by 14 is 4

Answer:

56

Step-by-step explanation:

First, you simplify 2/4 to 1/2. Then you figure that 28 * 2= 56/1= 56.

To double check your answer, put 56 in the box and see if the two fractions equal each other.

Answer:

Option 4.7% = 3,500 x 4.7% =$164.50 simple annual interest.

82.25 this is what Scott will pay in 6 months at simple interest.

Option 4.2% =3,500 x (1 +0.042/12)^6 =3,500 x 1.0035^6=$3,574.15.

3,500 =$74.15 this is what Scott will pay in 6 months at compounded interest.

The compound option is cheaper by: 74.15 =$8.10.

Probability that Sara does not wins a raffle is  [tex]\frac{3}{n+3}[/tex].

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

Given

Probability that Sara wins a raffle is given by the expression

P(win) = [tex]\frac{n}{n+3}[/tex]

Probability that Sara does not wins a raffle is given by

P(does not win) = 1 - [tex]\frac{n}{n+3}[/tex]

= [tex]\frac{n+3}{n+3} -\frac{n}{n+3}[/tex]

= [tex]\frac{n+3-n}{n+3}[/tex]

= [tex]\frac{3}{n+3}[/tex]

Thus, probability that Sara does not wins a raffle is  [tex]\frac{3}{n+3}[/tex].

Answer: Hi, the answer is 9/4 or C!

Step-by-step explanation:

You would take 2/7 and multiply both the top and bottom by 2 to make it 4/14, the. youd flip 4/14 into 14/4, then multiply the top numbers (9 and 14 by eachother to get 126) then multiply the bottom numbers ( 14 and 4 to get 56) and simplify the new fraction (126/56) to get 9/4!
