2/5

Answer: 1.3%

Step-by-step explanation:

The percentage decrease can be found using the formula:

percentage decrease = [(original value - new value) / original value] x 100%

Substituting the given values:

percentage decrease = [(9.79 - 9.66) / 9.79] x 100%

percentage decrease = 1.33%

Rounding to the nearest tenth of a percent, the percentage decrease is 1.3%.

Answer: hope this helps ♡

The percentage decrease is 1.33%.

Step-by-step explanation:

Percentage decrease: dividing the value by the total value and then multiplying it by 100

Total value: $9.79          Value: $9.79 - $9.66 = 0.13

[tex]\frac{0.13*100}{9.79}[/tex]  =

(0.13 × 100) ÷ 9.79 =

13 ÷ 9.79 =

1.32788559755 ≈ 1.33%

Haven't done this kinda problem in a while but I got 4/3 cm/s

Step-by-step explanation:

Using the coordinates given i put them into the formula:

        y1  -  y2

m=_________

        x1  -  x2

That gave me -16/-12, I simplified & got 4/3.

Answer: 900

Step-by-step explanation:

If 24 out of 80 students are undecided, that is 24/80, or 3/10 (0.3).

To find how many would be undecided out of 3,000 students, multiply 3/10 by 3,000/1, and you get 900, which is your answer

Answer:

Step-by-step explanation:

A school board randomly samples 80 students to determine their opinion on requiring school uniforms for the next school year. The table shows the results of the survey.

If there are 3,000 students in the district, how many students do you expect to be undecided about school uniforms?

we can solve with an equation

80 : 24 = 3000 : x

x = 24 * 3000 : 80

x = 900

Answer:

Negative 8y = 6

Step-by-step explanation:

-6x + 4y = -8

6x - 12y = 14

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

-8y = 6

Answer:

Plan A=3/2 hours Plan B=5/4 hours

Step-by-step explanation:

Plan A equals x

Plan B equals y

So than 3x+2y=7

And 8x+4y=17

Then you multiply the first equation by 2 to get rid of Y. 6x+4y=14 and 8x+4y=17 2x=3 x=1.5 y=1.25

Answer:

For A: The answer is (79-2x) degrees

For B: The answer is (169-2x) degrees

I dnt know the ture answer, but mabye this will help

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

Answer:C

Step-by-step explanation:

Answer:

There are 55 large boxes

and 70 small boxes.

Step-by-step explanation:

Let's assume that the number of large boxes is x, and the number of small boxes is y. We then can use how many pounds each box weighs to form a system of equations.

System:

[tex]50x+25y=4500\\x+y=125[/tex]

Step 1: Solve for a variable

[tex]x+y=125[/tex] is also [tex]y=-x+125[/tex]

Step 2: Substitute

[tex]50x+25(-x+125)=4500[/tex]

Step 3: Simplify

[tex]50x+-25x+3125=4500\\25x=1375\\x=55[/tex]

Step 4: Solve for y

[tex]y=-55+125\\y=70[/tex]

Answer:

(x,y) = (-3,7)

Answer: D. d > 9

Step-by-step explanation:

We have the inequality:

d/4 > 36

To solve for d, we need to isolate the variable d on one side of the inequality. We can do this by multiplying both sides of the inequality by 4:

d > 36 x 4

d > 144

Therefore, the answer is (D) d > 9, since any value of d greater than 9 would satisfy the inequality. We can also check that the other answer choices are incorrect:

   If d < 9, then d/4 < 9/4, which is less than 36. So, (A) d < 9 is not a valid solution.

   If d < 144, then d/4 < 144/4 = 36, which is less than 36. So, (B) d < 144 is not a valid solution.

   If d > 144, then d/4 > 144/4 = 36, which satisfies the inequality. So, (C) d > 144 is also a valid solution, but not the most inclusive one.

Answer:

the correct answer is option C: d > 144.

(22 - 4) / 6

The answer would be 3 miles on each of the six days

Answer:

In a week we have 7 days.

On the first day, Clare runs 4 miles.

On the other six days, she runs the same distance, let's call it D.

In total, she runs 22 miles.

Then:

4mi + 6*D = 22 mi

6*D = 22mi - 4mi = 18mi

D = 18mi/6 = 3mi.

Then the other 6 days, Clare runs 3 miles

Hope it helped! :)
