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

Answers

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.

The Gilberts are you designing a rectangular patio for their backyard. The patio has an area of 432 square feet. The width of the patio is 3/4 its length. What is the length of the patio?

A: 15 feet
B: 24 feet
C: 36 feet
D: 270 feet

Answers

Answer: B: 24 feet.

Step-by-step explanation:

Let's assume that the length of the rectangular patio is "L" feet. Then, the width of the patio would be 3/4 L.

The area of a rectangle is given by the formula A = L x W, where A is the area, L is the length, and W is the width. We know that the area of the patio is 432 square feet. Substituting the values of L and W, we get:

432 = L x (3/4 L)

Multiplying both sides by 4/3, we get:

(4/3) x 432 = L^2

Simplifying, we get:

576 = L^2

Taking the square root of both sides, we get:

L = ±24

Since the length cannot be negative, the length of the patio is 24 feet.

Therefore, the correct answer is option B: 24 feet.

B 24ft
X length
Width is 3/4x
X times 3/4x =432

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%

The circle graph describes the distribution of preferred music from a sample of 400 randomly selected middle school students.

a circle graph titled preferred music, with five sections labeled rock 13 percent, hip hop 25 percent, pop 35 percent, classical 13 percent, and jazz 14 percent

Which of the following conclusions can we draw from the circle graph?

Pop is the preferred music for 35 students.
Jazz is the preferred music for 56 students.
Together, Hip Hop, Rock, and Jazz are the preferred music for less than half the students.
Together, Hip Hop and Pop are the preferred music for 260 students.

Answers

Answer:

Step-by-step explanation:

(i) Number of people who are into classical music =10%

10% of pie chart =20 people.

1% ⇒ 10/20 ×100

and 100% ⇒ 10/20 ×100 × 100/ 100

​⇒200 people.

(ii) Light chart represent maximum number as it is 40% of total. ∴ Light music is liked by maximum people.

(iii)

Number of CD's of classical music ⇒ 100/10 × 1000(10%) =100

umber of CD's of semi classical music = 100/20 × 1000(20%) =200

just like that 30% is 300, 40% is 400.

Bryan randomly asked several students which type of animal they had at home as a pet. The results are in the pie chart below.

b. What percent of the students had birds?

c. How many total students did Bryan interview?

Answers

Answer:

60% of the students have dogs

10% of the students have birds

Bryan interviewed 200 students

Step-by-step explanation:

a.3/5 = 60%

b.60% + 30% = 90%

100% - 90% = 10%

c. 20 x 10 = 200

Answer: 60%, 10%, 200 students.

Step-by-step explanation:

Let's start with turning all of the values into percentages.

3/5 of the students said dogs. As a percentage, 3/5 is equal to 60%.

We now have two percentages, the amount of cats and the amount of dogs. 30%+60%=90%. So that leaves 10%, and that 10 percent is the 20 students who had birds.

If 20=10%, all we have to do is multiply 20 ten times to get to 100%. 20x10=200.

There were 200 students interviewed.

Question: The drying times in hours for a new paint are as follows:1.5,0.8,2.4,0.5,1.3,2.7,3.6,3.2,2.0,1.9 What is the median drying time

A. 1.99
B.1.95
C.1.9
D.1.5
E. NONE OF THE ABOVE

Answers

Answer:

First, we need to arrange the numbers in order:

0.5, 0.8, 1.3, 1.5, 1.9, 2.0, 2.4, 2.7, 3.2, 3.6

There are 10 numbers in the list, so the median is the middle value. In this case, the middle values are 1.9 and 2.0. To find the median, we take the average of these two numbers:

(1.9 + 2.0) / 2 = 1.95

Therefore, the median drying time is 1.95 hours, option B.

B. 1.95 because (1.9+2.0)/2= 1.95

The translation used to create the image include the following: A. 5 units down.

What is a translation?

In Mathematics and Geometry, the translation of a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image;

g(x) = f(x + N)

Conversely, the translation a geometric figure downward simply means subtracting a digit from the value on the positive y-coordinate (y-axis) of the pre-image; g(x) = f(x) - N.

Based on the information provided, we have:

(x, y)                               →                  (x + h, y + k)

(1, -1)                              →                   (1, -6).

1 + h = 1

h = 1 - 1

h = 0

-1 + k = -6

k = -6 + 1

k = -5.
