Answer:

  84 cm³

Step-by-step explanation:

There are formulas for the volumes of simple geometric solids: prism, cylinder, pyramid, cone, frustum of a pyramid or cone.

The formula for the volume of a rectangular prism is ...

  V = LWH . . . . . product of Length, Width, and Height

Put the numbers in place of the corresponding variables and do the arithmetic.

  V = (3 cm)(4 cm)(7 cm) = 84 cm³

The volume of this rectangular prism is 84 cubic centimeters.

Answer: y = -2x - 7

Step-by-step explanation:

The equation for a perpenducular line has a slope that is the negative inverse of the reference line, in this case x - 2y = 6.

Let's put this equation into standard slope-intercept form, y = mx+b, where m is the slope and b the y-intercept (the value of y when x is 0).

x - 2y = 6

- 2y = 6 - x

y = (1/2) x -3

The slope is (1/2), so a perpendicular line will have a slope of -2.

y = -2x + b

We can find b by using the given point ((-3,-1), a known solution):

-1 = -2*(-3) + b

-1 = 6 + b

b = -7

The perpendicular equation is y = -2x - 7

y = -2x

7^3+8^3=(7+8)(7^2−(7*8)+8^2)

               (15)(49-56+64)

                (15)(57)

7^3+8^3=855

a. 240 - 144 = 96 Adult males

260 - 129 = 131 Female children

b. 275-225 = 50 more children

c. 225/500 simplifies to 9/20 visitors are adults

d. 240:260

e. 144/500 chance that it is a male child

Okay so for a number 1 they want you to subtract the total from the child or adult. so for males, they want you to subtract 240 from 144. 240 - 144 equals 96 so there are 96 adults in males. moving on to the female we have to find how many children there are so, we have to subtract 260 from 129 which will equal 131. 131 is how many children are females.

For "B" we have to work out how many child visitors there are than adults. Easy we just have to subtract 275 from 225 which will equal 50!

Now for question C, we have to write the adult total in the lowest term what they mean by that is a fraction said to be written using the lowest terms if its numerator and denominator are relatively prime, that is, they have no common factors other than 1. So the lowest term for the adult is 9/4

Now for question D, they want us to make a ratio for the number of males and for the number of females. A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. The ratio for the male is 96:144 (for every 96 adults there are 144 children) The ratio for females is 129:131 (for every 129 female there are 131 children)!

For E it is a probaIlity that there is a 144/500 chance there's a male child! Not much I can explain for E because that's a hard one but that's the answer for E

Answer:

x=6

Step-by-step explanation:

5x-7=23

5x-7 +7=23+7

5x=30

30/5=6

x=6

Answer:

A) You would use the two points that are closest to the graphed line

(2,7) and (8,13)

B) Slope = change in Y over the change in X:

Slope = (13-7) / (8-2) = 6/6 = 1

Slope = 1

c) Point slope is written as y -y1 = m(x-x1) where m is the slope y1 is the first Y value and x1 is the first x value.

Equation is: y-7 = x-2

d) To rewrite y -7 = x-2 in slope intercept form, you need to isolate y.

To isolate Y add 7 to both sides:

y = x +5

Step-by-step explanation:

The equation of line which passes through point (-7,-2) and having slope 3 is y = 3x + 10.

What is Algebraic expression ?

Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.

Here, it is given that line passes though point (-3,1) and having slope of 3.

Now, Let us find the equation of the line using point-slope equation of line :

(y-y₁) = m(x-x₁)

Substituting all the values in above equation to get the equation of line :

(y-1) = 3(x-(-3))

y -1 = 3x + 9

y = 3x + 9 + 1

y = 3x + 10

Therefore, the equation of line which passes through point (-7,-2) and having slope 3 is y = 3x + 10.

Answer:

52 square feet.

Step-by-step explanation:

length*width=area

Top rectangle = 4ft*5ft = 20sq.ft

Bottom rectangle = 4ft*8ft = 32sq. ft

20+32=52 sq.ft OR (4*5)+(4*8)=52sq.ft

Answer: There are two formulas that we will use the first one is the y=m x+b and the second one is finding the perpendicular line.

Step-by-step explanation:

the first one is

y=m x+b

y= 3 x -12

the second one is

first find the negative reciprocal of the slope of the original line and use the point slope formula y- y,= m(x - x1) to find the line perpendicular to

Y= 3 x 1

X= 5

In the given figure, let the third angle of the triangle be x

From Angle sum property of a triangle, we know that :

so, the third angle will be 50°

and as we can observe here, the third angle of the triangle is equal to (3c + 2)° by vertical opposite angle pair.

so,

hence, value of c = 16°

Answer:

x = ± 5

Step-by-step explanation:

x² - 25 = 0 ( add 25 to both sides )

x² = 25 ( take square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5

That is x = - 5, x = 5
