The surface areas of two similar solids are 1008cm^2 and 1372ccm^2. the volume of the larger solid is 1801cm^3 find the volume of the smaller solid round your answer to the nearest hundredth

This can be treated as a proportion problem.

Larger solid: 
Surface area = 1,372 cm²
Volume = 1,801 cm³

Smaller solid:
Surface area = 1,008cm²
Volume = ?

1,372 / 1,801 = 1008 / x
1,372 * x = 1,801 * 1008
1,372x = 1,815,408
x = 1,815,408 / 1,372
x = 1,323.18

The volume of the smaller solid is 1,323.18 cm³

At Thursday’s basketball game, there were more than twice as many adult spectators as children. If x represents the number of adults and y represents the number of children, which inequality can be used to find the possible combinations of adults and children at the game?

Answer:

x > 2y

Step-by-step explanation:

It is given in the question that there were more than twice as many adult spectators as children.

If x represents the number of adults and y represents the number of children then inequality representing the relation will be

x > 2y

So inequality given above can be used to find the possible combinations of adults and children at the game.

Find the range of the function f(x)=4x-1 for the domain {-1,0,1,2,3}.

Answer:

Range defined as the complete set of possible values of the dependent variable,

or

The range is defined as the resulting y-values we get after substituting all the possible values of x from domain.

Given the function: f(x)=y = 4x-1

Also, x ∈Domain = {-1, 0, 1, 2, 3}

For x = -1;

y = 4(-1)-1 = -4 -1 = -5

For x = 0;

y = 4(0)-1 = 0 -1 = -1

For x = 1;

y = 4(1)-1 = 4-1 =3

For x = 2;

y = 4(2)-1 = 8-1 =7

For x = 3;

y = 4(3)-1 = 12-1 =11

Therefore, the range of the function are the set of all values of y i,e  

Range = {-5, -1, 3, 7 , 11}

Find the slope of the graph of the following: 9x-3y=15

Answer:

Equation of line is given by:

y = mx+b; ......[1]  where m is the slope and b is the y-intercept.

Given the equation of a line: 9x-3y =15

Subtract 9x from both sides we get;

9x-3y-9x =15-9x

Simplify:

-3y =15-9x

or

-3y =-9x+15

Divide by -3 both sides we get;

y = \frac{-9x+15}{-3}

or

y = \frac{-9x}{-3} + \frac{15}{-3}

Simplify:

y = 3x - 5

On comparing with equation [1] we have;

m = 3

Therefore, the slope of the graph of the following  9x-3y =15 is, 3

QUESTION POSTED AT 27/01/2020 - 12:42 AM

A customer went to a garden shop and bought some potting soil for $11.50 and 9 shrubs. the total bill was $94.75. write and solve an equation to find the price of each shrub. a. 9p 11.5p = $94.75; p = $4.62 b. 9p $11.50 = $94.75; p = $11.75 c. 9p $11.50 = $94.75; p = $9.25 d. 9(p $11.50) = $94.75; p = $5.00

Let

p---------> the price of each scrub

s----------> the price of the potting soil

T--------> total bill

we know that

 T=9p+s

in this problem

 T=\$94.75\\ s=\$11.50\\p=?

substitute the values in the formula above

 \$94.75=9p+\$11.50

solve for p

 9p=94.75-11.50

 9p=83.25

 p=9.25

therefore

the answer is the option C

 \$94.75=9p+\$11.50

 p=9.25

Find two consecutive odd numbers such that the sum of the first number and one-third of the second number is equal to fifty. 35 and 37 37 and 39 49 and 51

Answer:

37  and  39

Step-by-step explanation:

Let

x-------> the first odd number

x+2----> the second consecutive odd number

we know that

x+\frac{x+2}{3}=50 ----> linear equation that represent the situation

solve for x

Multiply by 3 both sides

3x+(x+2)=150

4x=148

x=37

Find the second consecutive odd number

Find s25 for 4 14 24 34

Answer:

The value of S_{25} is 3100.

Step-by-step explanation:

The given arithmetic sequence is

4, 14, 24, 34

First term of AP is 4 and common difference is

d=a_2-a_1\Rightarrow 14-4=10

We need to find the value of S_{25}. It means we have to find the sum of first 25 terms of the given AP.

The formula for sum of first n terms of an AP is

S_n=\frac{n}{2}[2a+(n-1)d]

where, n is number of terms, a is first term and d is common difference.

The sum of first 25 terms is

S_{25}=\frac{25}{2}[2(4)+(25-1)(10)]

S_{25}=\frac{25}{2}[8+240]

S_{25}=\frac{25}{2}[248]

S_{25}=3100

Therefore the value of S_{25} is 3100.

Answer:

The amount of last year's sales is:

$107,882

Step-by-step explanation:

We are given that:

Midtown antiques has found that sales have decreased 5% from last year. Sales this year are $102,488.

we have to  find the amount of last year's sales.

Let sales last year be x.

then  95% of x= 102488

⇒           \dfrac{95}{100}\times x = 102488\\\\x= \dfrac{102488\times 100}{95}\\ \\x=107882.10

⇒     x≈ 107882

Hence, correct option is:

b. $107,882
