-2 1/3 ÷ 4 2/3
Please help, I will grant the 1st person to answer correctly brainliest.

Answers

Answer 1

Answer: -1/2

Step-by-step explanation:

1. We know that -2 1/3 is also equal to -7/3, because we can multiply the denominator by the main number, and add the numerator.

2. We can do the same with 4 2/3, which would be 14/3.

3. Now, we are left with -7/3 divided by 14/3.

4. To make this easier, we can flip flop the 14/3 so we can multiply instead of divide, which leaves us with -7/3 x 3/14.

5. -7/3 x 3/14 = -21/42

6. We can simplify this to -1/2.

Step-by-step explanation:

The two legs ( shorter sides) have the right angle between them in a right triangle and

5^2 + 9^2   DOES equal 13^2

The answer would be D. Knowing that 52 + 122 = 132, draw the 5 cm side and the 12 cm
side with a right angle between them. The 13 cm side will fit to form a right triangle.

The following table shows several ordered pairs of a function, m(x)

4 6

Graph m(x) on a coordinate plane to determine whether or not the function represents a direct variation. In complete sentences, describe your conclusion and reasoning. Include your graph in your answer.

Answers

Answer:

  m(x) = 1.5x . . . . direct variation

Step-by-step explanation:

You want to know if the function m(x) represents direct variation, given a table of values.

Direct variation

An equation for direct variation is ...

  y = kx

where k is a constant that can be found as the ratio of any (x, y) pair:

  k = y/x

  k = -1.5/-1 = 1.5/1 = 3/2 = 6/4 = 1.5

The ratios are constant, hence m(x) is direct variation with a constant of variation of 1.5.

Graph

The graph of direct variation is a straight line through the origin. The given points lie on such a line.

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

The expression 9.00x+4.50y represents the total amount of money Harriet earns at her two jobs, where x represents the number of hours worked at job X and y represents the number of hours worked at job Y. Which shows an equivalent expression to the given expression and correctly describes the situation?

4.50(2x+y), which shows that Harriet earns twice as much per hour at job X than job Y.

4.50(2x+y), which shows that Harriet earns 4.50 times as much per hour at job X than job Y.

13.50xy, which shows that Harriet earns $13.50 each hour she works.

13.50xy, which shows that Harriet earns $13.50 every two hours she works.

Answers

The equivalent expression that correctly describes the situation is:

13.50xy, which shows that Harriet earns $13.50 for each hour she works.

This expression represents the total amount of money Harriet earns at both jobs, where x represents the number of hours worked at job X and y represents the number of hours worked at job Y. The coefficient of xy, which is 13.50, represents the amount of money Harriet earns per hour, regardless of which job she is working. Therefore, this expression accurately reflects the situation described

A cylindrical of oatmeal canister has a diameter of 4 inches and a height of 10 inches. The manufacturing company wants to package the oatmeal in square containers to cut back on wasted storage space. If the new carton has a square base with 4 inch sides, what is the minimum height it must have, to the nearest 1/4 inch, to hold the same volume of oatmeal? Use 3.14 for the value of π.

Answers

Step-by-step explanation:

Volume of cylinder = pi r^2 h

Volume of square container = s x s x h

they need to be equal

pi r^2 h = s^2 h

pi (2)^2 * 10   = 4^2 h            (diameter = 4   then radius = 2)

40pi / 16 = h = 7.9 in  = ~ 8 in   to the nearest 1/4 inch

The price of a technology stock was $9.79 yesterday. Today, the price fell to $9.66. Find the percentage decrease. Round your answer to the nearest tenth of a percent.

Answers

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%

Answers

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]

The answer would have to be 55 small and 55 large there is no other explanation
