Step-by-step explanation:
To find average add all of the numbers and divide by the number of numbers:
12 + 8 + 6 + 10 / 4 = 36 / 4 = 9
Answer: 9
Step-by-step explanation:
We can find the average using this formula =
Sum of all values in a data set ÷ the number of values = average (mean)
Step 1: We find the sum of the values
12 + 8 + 6 + 10 = 36
Step 2: We find the number of values
12 8 6 10
1 2 3 4
There are 4 values.
Step 3: We divide the sum of the values by the number of values
36 ÷ 4 = 9
So the answer is 9

The area of a rectangle is 48x®y7
square yards. If the length of the
rectangle is 6x2y4 yards, which
expression represents the width of the
rectangle in yards?
A. 42x4y3
B. 42x6y3
C. 8x4y3
D. 8x6y3
Answer:
D
Step-by-step explanation:
Remember, area equals width x height so you can set up this equation.
[tex]48x^8y^7=6x^2y^4 * w[/tex]
Solving for w,
[tex]\frac{48x^8y^7}{6x^2y^4} =w[/tex]
Simplifying,
[tex]8x^6y^3[/tex]
Thus, D is the answer
Find the area of this circle. Use 3 for pi.
Answer:
Area= 48 cm²
Step-by-step explanation:
Since the radius is 4, to get area, you must get 4 squared(4 x 4), which is 16. Then, multiply 16 to 3(pi), and the answer is 16 x 3 = 48.

5. Beverly is serving hamburgers and hot dogs at her
cookout. Hamburger meat costs $3 per pound, and hot
dogs cost $2 per pound. She wants to spend no more than
$30.
a. Write an inequality to describe the situation.
b. Graph the solutions on a coordinate plane.
C. Give two combinations of pounds of hamburger and
hot dogs that Beverly can buy.
Answer:
Hamburger meat
Cost = $2 per poundVolume = x poundsTotal cost = 2xHot dogs
Cost = $3 per poundVolume = y poundsTotal cost = 3yBudget = $30a) Inequality:
2x + 3y ≤ 30b) The graph is attached
c) Combinations are reflected on the graph
Find the area and Perimeter of the shape made
by connecting the following
points in order.
P (0,5) V (2,8) H (5,8) (5,5)
Answer:
area = 12 units²
perimeter = 17.61 units
Step-by-step explanation:
line VP² length = 2² + 3²
line VP = 3.61 units
perimeter = 5+3+3+3.61 = 17.61 units
area = (3)(3) + (1/2)(2)(3) = 12 units²
The base of a triangular pyramid is 21 inches squared. The volume is 63 inches cubed. What is the height of the pyramid?
Answer:
9
Step-by-step explanation:
So the formula for a triangular pyramid is v=1/3bh
you plug in the values and you get 63=1/3(21)(h) and since you are finding the height, you get h=63*3/21
and then you check answers with
63=1/3(21)(9) which is true so the height is 9

Gas from a local station costs $2.85 per gallon (in US dollars). Tara's car gets 13.4 kilometers to the liter.
About how much will it cost Tara to drive 640 kilometers if she buys the gas from that local gas station?
Answer:
$250.8
Step-by-step explanation:
13.4 = $2.85
13.4 x 15 = 111.0
111.0 = $42.75
111.0 x 6 = 666.0
666.0 - 26.0 = 640.0
$42.75 x 6 = $256.5
$2.85 x 2 = $5.07
$256.5 - $5.07 = $250.8

The total cost of 640 liters of gas is $35.91.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, Gas from a local station costs $2.85 per gallon (in US dollars).
We know that, 1 gallon = 3.785 liters
Tara's car gets 13.4 kilometers to the liter.
Number of liters of gas = 640/13.4
= 47.76 liters
Number of gallons = 47.76/3.785
= 12.6 gallons
Total cost = 12.6×2.85
= $35.91
Therefore, the total cost of 640 liters of gas is $35.91.

If a =3, b = 2 and c = 5, solve the following algebraic expressions: (3 marks)
a) 3c + 5 - b
b) b(4 - 2) + c
c) 4a - (2c)
Answer:
A) 18
B)9
C)-2
Step-by-step explanation:
Replace the a,b or c with the give number. So let’s say it’s says 2 + a. It would be 2+3.

A circle has a secant AC and a tangent AD that intersect outside of the circle. If the
measure of ZA is 29° and the measure of BD is 43°, then determine the measure of
CD.
Answer:
CD = 101°
Step-by-step explanation:
The secant- tangent angle DAB is hlf the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (CD - BD ) = 29° ( multiply both sides by 2 )
CD - BD = 58°, that is
CD - 43° = 58° ( add 43° to both sides )
CD = 101°
find the surface area of the triangular prism
Answer:
608 ft²
Step-by-step explanation:
1) Find the area of the bases
[tex]A=\frac{1}{2} bh[/tex] where b is the base length and h is the height
Plug in b and h
[tex]A=\frac{1}{2} (12)(8)\\A=48[/tex]
Multiply the answer by 2 (because there are 2 bases)
A=96
Therefore, the area of the two bases is 96 ft².
2) Find the area of the two sides facing up
[tex]A=lw[/tex] where l is the length and w is the width
Plug in l and w
[tex]A=10*16\\A=160[/tex]
Multiply the answer by 2 (because there are 2 sides)
A=320
Therefore, the area of these two sides is 320 ft².
3) Find the area of the bottom side
[tex]A=lw[/tex] where l is the length and w is the width
Plug in l and w
[tex]A=12*16\\A=192[/tex]
Therefore, the area of this side is 192 ft².
4) Add all the areas together
96 ft² + 320 ft² + 192 ft²
= 608 ft²
Therefore, the surface area of the triangular prism is 608 ft².
I hope this helps!
Answer:
608
Step-by-step explanation:
first off you have to find the area of the base
the base is 16 by 12 feet.
so you multiply them and you get
16*12=192 you will have to come back later for this number
next, you find the two outsides of the triangular prism.
they are 10 by 16
10*16=160 and there are two of them so you double it and get 320
now save the 320 too with the 192
now we are going to find the triangles
the formula for an area of a triangle is A=1/2h*w
so we plug in the height which is 8 and the width which is 12
A=1/2(8)*(12)
Simplify
A=48 once again there are two of them so we double it to make it 96
now take all your saved numbers and add them all up
96+320+192
this should give you an answer of 608
hope this helps! have a nice day:)

Answer:
x=2
Step-by-step explanation:
Primero, necesitamos calcular <<a>>
Sabemos que AD=BC y AB=CD porque lados opuestos congruentes
Entonces, vamos a calcular <<a>>.
Usamos AD y BC
2a-1=4a-15
suma 15 a ambos lados
2a+14=4
añada 2 en ambos lados
14=2a
divida
7=a
Ahora, usamos esta información para calcular <<x>>
Usamos CD=AB
2a-8=4x-2
pero sabemos que <<a>> es 7
entonces:
14-8=4x-2
6=4x-2
8=4x
2=x
<<x>> es 2

find the average rate of change, in simplest form, of the function over the interval 4\le x \le 74≤x≤7.
Answer:
[tex]Average\ Rate = \frac{104}{3}[/tex]
Step-by-step explanation:
Given
See attachment for table
Required
Determine the average rate of change over: 4≤x≤7.
Average rate of change is calculated as:
[tex]Average\ Rate = \frac{f(b) - f(a)}{b - a}[/tex]
Where:
[tex]a=4[/tex]
[tex]b = 7[/tex]
So:
[tex]Average\ Rate = \frac{f(b) - f(a)}{b - a}[/tex]
[tex]Average\ Rate = \frac{f(7) - f(4)}{7 - 4}[/tex]
[tex]Average\ Rate = \frac{f(7) - f(4)}{3}[/tex]
From that table:
f(4) =
f(7) =
So:
[tex]Average\ Rate = \frac{f(7) - f(4)}{3}[/tex]
[tex]Average\ Rate = \frac{108-4}{3}[/tex]
[tex]Average\ Rate = \frac{104}{3}[/tex]
Find the measure of angle x
Answer:
118° is given , so angle on a straight line =180°
therefore, 180°-118°=62°
the □(squared angle) indicates 90°
x°+62°+90°=180°
x°=180°-152°
x°=28°
if you want to recheck
28°+62°+90°=180°

What is 5/6 of 48?
In fractions
Answer:
30
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
5/6 of 48
In math, when the word "of" is used, it means multiplication.
5/6 of 48 ---> 5/6 × 48 = 40
How much does 6 goes in 48? Anser is 8 since 6 × 8 = 48. So this means that 6 and 48 cancels out remaining 8 and 5. 5 × 8 = 40 which is your answer. Hope this helps, thank you :) !!
