Answer:

Percentage change = 26.61 %

Step-by-step explanation:

Given

To determin

Percentage change = ?

Using the formula

Percentage change = (Final value - Initial value) / | Initial Vaue |  × 100%

                                  = (100​ - 78.98) / 78.98  × 100%

                                  = [21.02/78.98] × 100%

                                  = 0.266143 × 100%

                                  = 26.6143 %

Rounding off to 2 decimal places

                                   = 26.61 %

Therefore,    

Percentage change = 26.61 %

Answer:

g=64.8 meters

Step-by-step explanation:

[tex]\frac{26.1}{24.3}[/tex] = [tex]\frac{69.6}{g}[/tex]

69.6×24.3= 26.1×g

1,691.28=26.1g

64.8=g

g=64.8

Answer:

1.6

Step-by-step explanation:

7 and three tenths = 7 + 3/10 = 7.3

5 and seven tenths = 5 + 7/10 = 5.7

7.3-5.7 = 1.6 or can be written as 1 and six tenths, or 1 and three fifths.

Answer:

x = √6/2

Step-by-step explanation:

Side a = 1.73205 --> √3

Side b = 1.22474 --> √6/2

Side c = 1.22474 --> √6/2

To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that

X + 14 - 14 = 56 - 14

X=42

Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.

Answer:

Step-by-step explanation:

What is so special about the centroid? It is the distinct point that each of the three medians intersect. Therefore, from this definition we can figure out through some geometric proof (I'm not going to go into this) the following:

If you draw the medians, you will notice that they intersect at exactly one point. That is the centroid. You will also notice that the centroid splits the median into 2 parts: top and bottom. The proof suggests that the top part is 2 times the bottom part.

In this case, the centroid is D and the top point is B. Therefore, we can figure out that BD, the top part, must be 2 times the bottom part, which is BE. Thus, we determine that BE is 2 because 4/2 = 2.

I would encourage you to draw it out so you can understand. Unfortunately, typing may not work all the time

Answer:

Yes

Step-by-step explanation:

In the first equation, sub in (-3x/2) for y:

3x+4y=12

3x+4(-3x/2)=12

3x-(12x/2)=12

3x-6x=12

-3x=12

x=-4

y=-3x/2

y=-3(-4)/2

y=12/2

y=6

Since x=-4 and y=6, (-4,6) is a solution.

Answer:

H0 is rejected and Ha is accepted that the students show a higher population mean math score on the SAT if their parents attained a higher level of education.

Step-by-step explanation:

Part a:

The null and alternate hypothesis can be formulated as

H0 : u1 ≤ u2 the two means ( of students whose parents did or did not attain a higher level of education) are equal .

against the claim

Ha: u1 > u2 the students show a higher population mean math score on the SAT if their parents attained a higher level of education.

Part b:

The point estimate of the difference between the means for the two populations is the difference of sample means

Step-by-step explanation:

Given

-30 = - 0.4 k

30 = 0.4k

k = 30 / 0.4

k = 75

hope it helps :)

Answer:

Simplifying

-38 = -0.4k

Solving

-38 = -0.4k

Solving for variable 'k'.

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

Add '0.4k' to each side of the equation.

-38 + 0.4k = -0.4k + 0.4k

Combine like terms: -0.4k + 0.4k = 0.0

-38 + 0.4k = 0.0

Add '38' to each side of the equation.

-38 + 38 + 0.4k = 0.0 + 38

Combine like terms: -38 + 38 = 0

0 + 0.4k = 0.0 + 38

0.4k = 0.0 + 38

Combine like terms: 0.0 + 38 = 38

0.4k = 38

Divide each side by '0.4'.

k = 95

Simplifying

k = 95

Find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.

Multiples of 24:

24, 48, 72, 96, 120, 144, 168, 192, 216

Multiples of 84:

84, 168, 252, 336

Therefore,

LCM(24, 84) = 168

Answer:

612 dollars

Step-by-step explanation:

From the given information:

Amount of the total mixture = 6000 pounds

Also, for each batch, there needs to be at least 25% bluegrass seed.

It implies that:

In 6000 pounds, there are (25×6000)/100 = 1500 pounds of bluegrass seed.

The remaining amount of (6000 - 1500 = 4500)pounds will be for rye and Bermuda.

Suppose the amount of rye seeds = x pounds

while that of Bermuda is (4500 - x) pounds

Then, since the amount of Bermuda contains no more than 2/3 of that of rye.

The equation can be written as:

[tex]( 4500 - x) = \dfrac{2x}{3}[/tex]

13500 - 3x = 2x

13500 = 5x

[tex]x = \dfrac{13500}{5}[/tex]

x = 2700

Now, the amount of rye seed = 2700 pounds

while that of Bermuda seed = 4500 - 2700 = 1800 pounds

However, For Bluegrass, we are told that the cost of 1 pound is 12 cents.

So, the cost of 1500 bluegrass seeds = 12 × 1500 = 18000 cents

For rye seed; cost of 1 pound = 14 cents

the cost of 2700 rye seeds = 14 × 2700 = 37800 cents

For Bermuda seed; cost of 1 pound = 3 cents

the cost of 1800 rye seeds = 3 × 1800 = 5400 cents

The total amount = (18000 + 37800 + 5400) = 61200 cents

Recall that:

100 cents = 1 dollars

61200 cents = x dollars

x = 61200 cents/100 cents

x = 612 dollars

Thus, the minimum cost is 612 dollars.

Answer:

12

Step-by-step explanation:

add the numbers to get the total then divide the total by the amount of columns/numbers.

12 + 12 + 18 + 6 = 48

48 / 4 = 12

Answer:

12 + 12 + 18 + 6 = 48

48/4 = 12

Answer:

12%

Step-by-step explanation:

If we subtract both numbers we get 540.

[tex]\frac{540}{4500} = \frac{x}{100} \\[/tex]

540 x 100 = 54,000

54,000 / 4,500 = 12%

Step-by-step explanation:

1) first eliminate constant(number without variable) you eliminate constant by doing the inverse operation(if constant is being added, then subtract)(if constant is being subtracted, then add it)

ex: if   x+9=32

subtract 9 from both sides to get rid of it

x=23

2) if there is another constant but this constant is being multiplied/divided then do the opposite operation to remove it

you could multiply by 3 on both sides:

x+9=69

x=60

Answer:

1) first eliminate constant(number without variable) you eliminate constant by doing the inverse operation(if constant is being added, then subtract)(if constant is being subtracted, then add it)
