marilyns teacher slowed her to take a makeup test she scored 24/60 on the original test and 28/40 on the makeup test by what percentage did marilyn improve her score

Answers

Answer 1
First test: 24/60 = 0.4 = 40%
Second test: 28/40 = 0.7 = 70%

So you could say 30% improvement, but if the way it’s worded makes me wonder if they want to know what percentage of 40 is 70.

0.4x = 0.7
0.7/0.4 = x
x = 1.75 = 175%

Which one sounds more like what you’re learning in class right now? That’s the answer I would go with.

Mrs. Carter baked 100 muffins for a bake sale. The muffins were sold in packages of 2. There were 12 muffins left. Write an equation to find how
many customers bought muffins at the bake sale. Model the equation using a flowchart

Answers

Answer:

2n + 12 = 100 (Equation)2n = 88 (Solving)n = 44 people bought muffins at the bake sale. (Solving)

Step-by-step explanation:

100 muffins, and 2 in each package. Therefore, there are 50 packages. However, in the end, there are 12 left, so there must have been 6 packages left.

Answer:

2n+12=100 ...........

3(2x+d)+c(x+5)=10x+17 find c and d

Answers

Answer:

c = 4, d = - 1

Step-by-step explanation:

Expand and simplify left side, then compare coefficients of like terms on the right side, that is

3(2x + d) + c(x + 5) ← distribute parenthesis

6x + 3d + cx + 5c

= x(6 + c) + 3d + 5c

Compare terms with those on the right side

coefficients of x- terms

6 + c = 10 ( subtract 6 from both sides )

c = 4

--------------

constant terms

3d + 5c = 17, that is

3d + 5(4) = 17

3d + 20 = 17 ( subtract 20 from both sides )

3d = - 3 ( divide both sides by 3 )

d = - 1

The value of c and d if 3(2x+d)+c(x+5)=10x+17  is 4 and -1 respectively

Given the equation:

3(2x+d)+c(x+5)=10x+17

Expand the bracket

6x + 3d + cx + 5c = 10x + 17

Collect the like terms

6x+cx + 3d + 5c = 10x + 17

x(6+c) + 3d + 5c = 10x + 17

Compare the coefficients of x on both sides

x(6+c) = 10x

6+c = 10

c = 10 - 6

c = 4

Similarly:

3d + 5c = 17

3d + 5(4) = 17

3d + 20 = 17

3d = 17 - 20

3d = -3

d =-3/3

d = -1

Hence the value of c and d if 3(2x+d)+c(x+5)=10x+17  is 4 and -1 respectively

In ΔTUV, t = 320 inches, u = 360 inches and ∠V=81°. Find the area of ΔTUV, to the nearest square inch.

Answers

Answer:

[tex]Area = 56892in^2[/tex]

Step-by-step explanation:

Given

[tex]\triangle TUV[/tex]

[tex]t = 320in[/tex]

[tex]u = 360in[/tex]

[tex]\angle V = 81^\circ[/tex]

Required

Calculate the area

Given two sides and a middle angle, the area of a triangle is:

[tex]Area = \frac{1}{2}ab*sinC[/tex]

In this case, it is:

[tex]Area = \frac{1}{2}tu*sinV[/tex]

[tex]Area = \frac{1}{2}*320*360*sin(81)[/tex]

[tex]Area = \frac{1}{2}*320*360*0.9877[/tex]

[tex]Area = 56891.52[/tex]

Answers

Answer:

t = 4.5

Step-by-step explanation:

Distribute 3 to the parentheses:

3(t + 4) = 25.5

3t + 12 = 25.5

Subtract 12 from both sides:

3t = 13.5

t = 4.5

So, the answer is t = 4.5
