what is the surface area

Answer:

f(2) = 0

f(-4) = 24

Step-by-step explanation:

[tex] \hookrightarrow \: { \tt{ \sf{f(n) = {n}^{2} - 2n }}}[/tex]

When n is 2 ✔

[tex] \dashrightarrow \: { \tt{f(2) = {(2)}^{2} - (2 \times 2) = 4 - 4 = 0}} \\ [/tex]

When n is -2 ✖

[tex] \dashrightarrow { \tt{ {( - 2)}^{2} - (2 \times - 2) = 4 + 4 = 8 }}[/tex]

When n is 1 ✖

[tex] \dashrightarrow{ \tt{f(1) = {(1)}^{2} - (2 \times 1) = - 1 }}[/tex]

When n is 5 ✖

[tex] \dashrightarrow{ \tt{f(5) = {(5)}^{2} - (2 \times 5) = 15}}[/tex]

When n is -4 ✔

[tex] \dashrightarrow{ \tt{f( - 4) = {( - 4)}^{2} - (2 \times - 4) }} \\ { \tt{ = 16 + 8}} \\ { \tt{ = 24}}[/tex]

Answer:x=9689

Step-by-step explanation:based on given conitions,formulate:13205+x=22894

Answer:

12,955 + x = 24,894

x = 11,939

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

Given : 7 11 4 2 =10. To Find : make it true using order of operations. Solution: 7 11 4 2 =10. 7 + 11 - 4 x 2 = 10. Applying BODMAS.

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.

B. A Bowling ball

3 kilograms is approximately 7 pounds, the weight of most Bowling balls

B. A Bowling ball

Step-by-step explanation:

Options A and D are most likely to weigh more than 3kg and option C will most likely weigh less but option B can weigh up to 3kg

Answer:

no

Step-by-step explanation:

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.

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:

Step-by-step explanation:

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.

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

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.

#SPJ1

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%

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.

Hope this helped :)
