18% of what number is 99

7. Numericals

Nadusha1986 [10]

Answer:

i = 1000cm2

ii = 100000cm3

Step-by-step explanation:

for q i

surface area of base = l* b

= 50* 20

1000cm^2

for q 2

volume l*b*h

= 50*20*10

= 100000cm^3

hope it will be helpfull

The high school tennis team is selling tennis balls to raise $500 for new equipment. They sell the balls for $4 each. A case h

Citrus2011 [14]

Answer:

1.75 cases need to be sold

Step-by-step explanation:

The complete question is

The high school tennis team is selling tennis balls to raise $500 for new equipment.They sell the balls for $2 each.

4).How many cases of tennis balls does the tennis team have to sell in order to raise enough money for new equipment.

Solution

Price of each ball = $4

No. of balls in each package = 3

Total number of balls that need to sold in order to raise $500 is

$\frac{500}{4} = 125$

one package = 3balls

Hence no of packages to be sold

$\frac{125}{3} = 41$ packages and 2 balls or total 42 packages

1 case has 24 packages , thus total number of cases to be sold = $\frac{42}{24} = \frac{14}{8} = \frac{7}{4} = 1.75$

The graph of the function f(30x) can be obtained from the graph of y=f(x) by one of the following actions:

charle [14.2K]

Answer:

Horizontally compress the graph of f(x) by a factor of 30 ⇒ answer b

Step-by-step explanation:

* Lets revise the vertical and horizontal stretching or compressing

a graph

- A vertical stretching is the stretching of the graph away from the

x-axis

- If k > 1, then the graph of y = k•f(x) is the graph of f(x) vertically

stretched by multiplying each of its y-coordinates by k

- A vertical compression is the squeezing of the graph toward

the x-axis.

- If 0 < k < 1 , then the graph of y = k•f(x) is the graph of f(x)

vertically

compressed by multiplying each of its y-coordinates by k

- A horizontal stretching is the stretching of the graph away from

the y-axis

- If 0 < k < 1 , then the graph y = f(k·x) is the graph of f(x) horizontally

stretched by dividing each of its x-coordinates by k

- A horizontal compression is the squeezing of the graph toward

the y-axis.

- If k > 1, then the graph of y = f(k•x) is the graph of f(x) horizontally

compressed by dividing each of its x-coordinates by k.

* Lets solve the problem

- The graph of the function f(30 x) can be obtained from the

graph of y = f(x)

∵ x multiplied by 30

∴ f(x) is stretched or compressed horizontally

- If the factor greater than 1 then the graph compressed

∵ 30 > 1

∴ f(x) is compressed horizontally by scale factor 30 to obtained

the function f(30 x)

* Horizontally compress the graph of f(x) by a factor of 30

I need help solving a math problem.A total of 516 tickets were sold for the school play. They were either adult tickets or stude

vfiekz [6]

The total number of tickets sold = 516.

Let the number of student tickets sold be S.

Let the number of adult tickets sold be A.

According to the given condition,

$S\text{ = 3A \_\_\_\_\_\_\_\lparen1\rparen}$

Also,

$\begin{gathered} A+\text{ S = 516} \\ A+\text{ 3A = 516} \\ 4A\text{ = 516} \\ A\text{ = 129} \end{gathered}$

Thus 129 adult tickets were sold.
