Answer:

sample response

Step-by-step explanation: :)

You would first calculate the area of the base, which is length times width. You would then calculate the area of the faces, which is 1 2 (base times height) and multiply the result by 4 for the 4 faces. Finally, add the area of the base and the areas of the faces.

Answer:

given

area of triangle = 48

height(h)=12

base(b) =‽

now,

area of triangle(a) =1/2 base×height

48=1/2 b×12

48=b×6

b=8

Answer:

3 laps per day

Step-by-step explanation:

Divide 45 laps by 5 days to get how many laps they ran per day

45/5 = 9 laps per day

The tennis players run 6 less laps per day than the soccer players so subtract 6 laps from 9 laps to get their daily laps

6-9 = 3 laps per day

Circumference of circle with diameter 7 units is 22 square units,

Diameter of circle with area 121π square units is 22 units and

Area of circle with circumference 20π units is 314 square units

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

a) Area of circle with radius 10 units

A = πr²

A = 3.14 x (10)²

A = 3.14 x 100

A = 314 sq. units

b) Circumference of circle with diameter 7 units

C = πd

C = 3.14×7

C = 21.98 units

c) Diameter of circle with area 121π square units

Answer:

A = 240 units²

Step-by-step explanation:

the area (A) of a regular polygon is

A = [tex]\frac{1}{2}[/tex] pa ( p is the perimeter and a the apothem )

here p = 8 × 6 = 48 ( an octagon has 8 sides ) and a = 10 , then

A = [tex]\frac{1}{2}[/tex] × 48 × 10 = 24 × 10 = 240 units²

Answer:

Step-by-step explanation:

Preliminary task

Draw a regular octagon.

Draw a perpendicular from the side's midpoint to the center. (That is the  apothem).

Draw two radii from the center of the side to the center of of the octagon. The endpoints of these two radii is the endpoints of the octagon's side.

The octagon has 8 such triangles.

Area one triangle

Area = 1/2 * side *  apothem

side = 6

apothem = 10

Area = 1/2 6 * 10

Area = 30

Area of 8 such triangles.

Area = 8 * area of 1 triangle

area 1 triangle = 30

Area of 8 such triangles = 30*8 = 240

Answer:

D)  30

Step-by-step explanation:

AB is the diameter of the circle

AB = AE + EB

     = 25 + 9

     = 34

OB, OC and OD are all the radius of the circle.

Radius = half the diameter

Therefore, OB = OC = OD = 34 ÷ 2 = 17

ΔCOD is an isosceles triangle with congruent sides OC and OD, and height OE

OE = OB - 9

     = 17 - 9

     = 8

Base of isosceles triangle = [tex]2\sqrt{a^2-h^2}[/tex]

(where a is one of the congruent side lengths and h is the height)

[tex]\implies CD=2\sqrt{OD^2-OE^2}[/tex]

[tex]\implies CD=2\sqrt{17^2-8^2}[/tex]

The required Henry needs to score 18 points in his next game to have an average of 24 points per game.

The mean of the values is the ratio of the total sum of values to the number of values.

Here,
average = sum of all scores/number of scores

We know that Henry has played four games so far, and his scores are 30, 29, 22, and 21 points. Therefore, the sum of his scores is:

sum of scores = 30 + 29 + 22 + 21 = 102

Let's assume that Henry scores x points in his next game. Then, his total score for all five games will be,

total score = 102 + x

If his average is 24 points per game, we can set up the equation:

24 = (102 + x) / 5

120 = 102 + x

x = 18

Therefore, Henry needs to score 18 points in his next game to have an average of 24 points per game.

Step-by-step explanation:

You always do the operations in parenthese first.

"The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)." -khanacademy . org > ...> order of operations

Answer:

B. (20 ÷ 4 - 2 + 1)

Solved, the equation equals 29.

Step-by-step explanation:

Order of operations: PEMDAS

Parantheses

Exponents

Multiplication

Division

Addition

Subtraction

9 + 5 × 2(20 ÷ 4 - 2 + 1)

The first step would be to do the operations inside the parantheses.

9 + 5 × 2(20 ÷ 4 - 2 + 1)

So,

(20 ÷ 4 - 2 + 1)

There are several operations, so lets look at PEMDAS again..

Okay, so we dont have any exponents, or multiplication inside the parantheses, so next step is divide.

(20 ÷ 4 - 2 + 1)

20 ÷ 4 = 5

So, we replace '20 ÷ 4' with '5'

(5 - 2 + 1)

Next, we add.

(5 - 2 + 1)

2 + 1 = 3

Now, replace '2 + 1' with '3'

(5 - 3)

Now, we just subtract 3 from 5.

5 - 3 = 2

So now our equation looks like this:

9 + 5 × 2(2)

Now, we have to do the parantheses again. But this time we are going to treat the parantheses as a multiplication symbol:

9 + 5 × 2(2) → 2 × 2 = 4

↓

9 + 5 × 4

Now, we have to multiply.

9 + 5 × 4 → 20

↓

9 + 20 = 29

So, when you solve the equation, you get 29.

The measure of the angle ∠PGL will be equal to 107 degrees.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

In triangles ΔPGL and ΔNHE,

PG  = NH (given)

GL = HE (given)

If the angle ∠PGL and ∠NHE become congruent, the triangle ΔPGL and ΔNHE will be congruent to each other.

∠PGL = ∠NHE

∠PGL = 107°

The measure of the angle ∠PGL will be equal to 107 degrees.

When graphing the following equation shown below:

Answer:

{f(x) ∈ ℝ | f(x) ≥ 3}

Step-by-step explanation:

The range of a function is the output values (y-values).

Absolute value is the distance of x from zero, so it is never negative.  It is denoted by a bar on either side of the term.

Therefore, as |x| ≥ 0 then |x| +3 ≥ 3
