Consider the formula for surface area

Answer:

I think the answer is letter A.

Answer:

its A

Step-by-step explanation:

just expand it out

I'm guessing you don't know how to multiply fractions, just do a/b *c/d = ac/bd

and a(b+c) = ab+ ac

Answer:

The median is 45

Step-by-step explanation:

Answer:

45

Step-by-step explanation:

The median is the middle number.

The middle number is expressed as the middle line of the box in a box plot

The middle line hovers over the number 45 which means that the middle number or median is 45

Answer:  no solutions

Step-by-step explanation:

y = −7x + 3

y + 7x = 10

Answer:

No solution the lines are parallel

Step-by-step explanation:

y = 6x  +x + 3

y = 7x + 3

y = 7x + 3 + 1

y = 7x + 4

No solution the lines are parallel

Answer:

w = 12ds/x

Step-by-step explanation:

Here, we want to write the equation in terms of w

What we simply do here is to bring x and w to reach others side

we have this as;

w = 12ds/x

Answer: [tex]8x^3y[/tex]

Step-by-step explanation:

Given

The area of a rectangle is [tex]24x^5y^7[/tex]

The length of the rectangle is [tex]3x^2y^6[/tex]

The area is given by the product of length and width

Suppose, w is the width of the area

[tex]\therefore A=l\times w\\\Rightarrow 24x^5y^7=3x^2y^6\times w\\\\\Rightarrow w=\dfrac{24x^5y^7}{3x^2y^6}\\\\\Rightarrow w=8x^3y[/tex]

Thus, the width of the rectangle is [tex]8x^3y[/tex]

Answer:

V = 18.84 units³

Step-by-step explanation:

The formula for the volume of a cone of base radius r and height h is

V = (1/3)(pi)(r²)(h).

Here, with pi = 3.14, r = 3 and h = 2, we get:

V = 18.84 units³

Answer:

x = - 6, y = 15

Step-by-step explanation:

3x + 2y = 12

3(-6) + 2(15) = 12

-18 + 30 = 12

----------------------------------------

2x - 3y = -57

2(-6) - 3(15) = -57

-12 - 45 = -57

First you have to find the factors for these zeros

f(x) = (x-2)(x+8)

Then FOIL to come up with the function

f(x) = x2+8x-2x-16

Combine like terms

f(x) = x2+6x-16

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Total money needed= $5,000

Percentage raised= 75%

To calculate the amount collected and the difference required, we need to use the following formulas:

Total collected= 5,000*0.75

Total collected= $3,750

Difference= 5,000 - 3,750

Difference= $1,250

Answer: [tex]56,900\left( 0.919\right)^x[/tex]

Step-by-step explanation:

Given

Marcos purchased a sailboat for [tex]\$56,900[/tex]

Each year the boat will decrease in value by [tex]8.1\%[/tex]

After 1 year it is

[tex]\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\[/tex]

after another year it becomes

[tex]\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2[/tex]

After [tex]x[/tex] years it is

[tex]\Rightarrow 56,900\left( 1-0.081\right)^x[/tex]

[tex]\Rightarrow 56,900\left( 0.919\right)^x[/tex]

Answer:

9

Step-by-step explanation:

Answer: (x - 5)^2 + (y - 7)^2 = 50

Step-by-step explanation:

The general equation for a circle is (x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre

Use Pythagoras to find r^2

r^2 = (5 - -2)^2 + (7 - 8)^2

= 7^2 + (-1)^2

= 50

So the circle is (x - 5)^2 + (y - 7)^2 = 50

Answer:

Number of T-SHIRT sold = x = 110

Number of sweatshirt = y = 40

Step-by-step explanation:

Let

Number of T-SHIRT sold = x

Number of sweatshirt = y

The number of T-shirts sold was 10 fewer than three times the number of sweatshirts sold.

x = 3y - 10

Cost of each T-SHIRT = $11

Cost of sweatshirt = $19

Total cost = $1,970

Total = x + y

1,970 = 11(3y - 10) + 19y

1970 = 33y - 110 + 19y

1970 + 110 = 33y + 19y

2080 = 52y

y = 2,080/52

y = 40

Substitute y = 40 into

x = 3y - 10

x = 3(40) - 10

x = 120 - 10

x = 110

Number of T-SHIRT sold = x = 110

Number of sweatshirt = y = 40

Answer:

110

Step-by-step explanation:

Answer:

9a = 11a - 2a

9a = 9a

Step-by-step explanation:

9a = 11a - 2a

11 - 2 = 9

Similarly, 11a - 2a = 9a

Eleven minus two equals nine. Similarly, 11a minus 2a equals 9a. You can subtract them because they both have the same variable a.

Answer:

42.7%

Step-by-step explanation:

Correlation is a statistical measure of inter relationship between two variables' co movement.

Correlation coefficient denotes the direction & extent by which two variables' (same or opposite) movement is linked to each other.

Coefficient of determination = r^2 symbolises percentage of variation in one variable, that can be explained by variation in other variable.

So, in this case r^2 = (0.654)^2 = 0.427716 ; Hence approx 42.7% variation in one variable can be explained by variation in other.
