Area of the Composite Figure:
in?
8 in
bi
16in
Answer:
86.14 in.²
Step-by-step explanation:
Area of the composite figure = area of semicircle + area of rectangle + area of triangle
= (½πr²) + (L*W) + (½bh)
Where,
r = ½*6 = 3 in.
L = 8 in.
W = 6 in.
b = 16 - 8 = 8 in.
h = 6 in.
Plug in the values and solve
Area of composite figure = (½*π*3²) + (8*6) + (½*8*6)
= 14.14 + 48 + 24
= 86.14 in.²
What is the solution to this set of equations?
2x+2y=6
x-y=3
Which answer is correct?
(0,-3)
(3,0)
(6,3)
(0,3)
Answer:
(3,0)
Step-by-step explanation:
2x + 2y = 6 divide thru by 2 and you get x + y = 3
Name x + y = 3 equation (1) and x - y = 3 equation (2)
Add equations (1) and (2)
(1) x+ y = 3
(2) x - y = 3
2x = 6
x = 3
Substitute x = 3 into equation (1). So, 3 + y = 3
y = 0
Problem ID: PRABMTFA A solid with volume 12 cubic units is dilated by a scale factor of k. Find the volume of the image for each given value of k.
k=1/4
Answer:
Step-by-step explanation:
3/16
You can use the fact that you can think of the solid as made up of 12 cubes with side length of 1 unit.
The volume of the image of the dilated solid is for k = 1/4 is
3/16 cubic units
How can we interpret measurement of something?Remember that volume, area, length etc all are measured relatively.
If you are 1.7 meters tall, then you're height is measured relative to meters. This is called unit of the measurement. It means that if we collect 1 meter and 0.7 meters too,they together will be equally tall as you.
Similarly, if we say that a triangle has area of 40 square inches, then it means that its area is equal to 40 squares of 1 inch sides.
Using above understanding to find the volume of the dilated solidSince the original solid was of 12 cubic units. it means its volume was equal to the total volume of 12 cubes with 1 unit side length.
Now since the scale factor of the dilation is k, that means each of the cube got its side length multiplied by k
Now volume of 12 cubes with side length k units is given by
[tex]V = 12 \times k^3[/tex]
Since it is given that k = 1/4, we have:
[tex]V = 12 \times (\dfrac{1}{4})^3 = \dfrac{3}{16} \: \rm unit^3[/tex] now there are 3/16 cubes with 1 unit length.
Thus,
The volume of the image of the dilated solid is for k = 1/4 is
3/16 cubic units

2x - x + 7 = x + 3 + 4
Answer:0
Step-by-step explanation:
Simplifying
2x + -1x + 7 = x + 3 + 4
Reorder the terms:
7 + 2x + -1x = x + 3 + 4
Combine like terms: 2x + -1x = 1x
7 + 1x = x + 3 + 4
Reorder the terms:
7 + 1x = 3 + 4 + x
Combine like terms: 3 + 4 = 7
7 + 1x = 7 + x
Add '-7' to each side of the equation.
7 + -7 + 1x = 7 + -7 + x
Combine like terms: 7 + -7 = 0
0 + 1x = 7 + -7 + x
1x = 7 + -7 + x
Combine like terms: 7 + -7 = 0
1x = 0 + x
1x = x
Solving
1x = x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
1x + -1x = x + -1x
Combine like terms: 1x + -1x = 0
0 = x + -1x
Combine like terms: x + -1x = 0
0 = 0
Simplifying
0 = 0
The solution to this equation could not be determined.

The total surface area of a cube is 600
in2. What is the length of each side of the
cube? It is in.
Answer:
10
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces.
600 / 6 = 100

Answer:
11
Step-by-step explanation:
Do kcf (keep,change,flip)
First, covert 2 3/4 into an improper fraction
Then after you do that you get 11/4
so you do the equation 11/4 ÷ 1/4
when you do kcf it would be 11/4 × 4/1=
11/4×4/1=44/4 simplify divide both by 4 = 11

a. 13 square ft
b. 15.9 square ft
c. 18 square ft
d. 234 square ft
Answer:
D) 234 square ft
Step-by-step explanation:
The formula for area is: length x width.
The length is 9 in or (using the scale) 18 ft.
The width is 6.5 inches or (using the scale) 13 ft.
Multiply 18 x 13 to get 234 square ft.

7x = 14
Answer:
3+x sqrt 7 -13 is a radical equation.
The value of radical equation is,
⇒ 7√x = 14
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
All the equations are,
⇒ x +√5 = 12
⇒ x² = 16
⇒ 3 + x√7 = 13
⇒ 7√x = 14
Since, A radical equation is an equation with at least one variable put on a radical form.
In this question, there is only one kind of variable which is x.
Then, you need to find the equation where x is in the radical form.
Hence, The radical form can be expressed with square root symbol.
Therefore, The option with √x would be only,
⇒ 7√x = 14
Thus, The value of radical equation is,
⇒ 7√x = 14

Answer:
a) 46° b) 66° c) 4 cm
Step-by-step explanation:
a) because it is isosceles triangle, therefore, 2 opposite angles, and angle sum of triangle is 180 so 180-67-67=46
b) because again, isosceles triangle so two opposite sides,
x+x+48=180
2x=132
x=66
c)because it is equilateral, so therefore all angles are 60 degrees and all sides equal.

You treat your friend to lunch. The food bill was $30.24. A 7% sales tax will be added and you want to leave a 20% tip.
a. Find the sales tax.
b. Find the tip.
c. Find the total amount you pay for lunch.
Answer:
a. $2.12
b. $6.45
c. $38.81
Step-by-step explanation:
a.
I'll convert 30.24 and 7% into fractions.
756/25 * 7/100
Cross cancel 756 and 100 (GCF is 4)
189/25 * 7/25
Convert above into a single fraction
(189 * 7)/(25 * 25)
Multiply 189 by 7, then 25 by 25.
1323/625
Divide, then round to the nearest cent
$2.1168 ≈ $2.12 in sales tax
b.
Like before, I'll convert $32.26 ($30.24 + $2.12) and 20% into fractions.
1613/50 * 1/5
Multiply 50 by 5.
1613/250
Divide, then round to the nearest cent.
$6.452 ≈ $6.45 in tip money
c.
This is probably the simplest part of the 3. Just add $30.24 + $2.12 + $6.45.
$30.24 + $2.12 + $6.45
$32.36 + $6.45
You pay a total of $38.81 for lunch.

QUESTION~
For the function in Item 2, what is
the average rate of change over
the interval 2 ≤ x ≤ 3?
A.(0)
B.(1)
C.(5)
D.(25)
Answer:
See below.
Step-by-step explanation:
You don't show what the function is, but I'll explain how to do it.
The average rate of change of function f(x), from x = a to x = b, is given by the fraction:
[tex] \dfrac{f(b) - f(a)}{b - a} [/tex]
Since I don't know what the function is, I cannot evaluate the function at x = a and at x = b, which in your case are x = 2 and x = 3, but you can do it.
Here are the steps you need to do:
1) Evaluate the function at x = 3. Get a value for f(3).
2) Evaluate the function at x = 2. Get a value for f(2).
3) Evaluate the following fraction, after writing the values for f(3) and f(2) that you found in steps 1) and 2) above.
[tex] \dfrac{f(3) - f(2)}{3 - 2} [/tex]
The denominator above is easy. It's just 1.
Try it and see what you get. You can write the function and your answer in the comments if you need more help.

Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
3.75=3.75/1
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10 to the power of 2 = 100
3.75/1×100/100=375/100
Find the Greatest Common Factor (GCF) of 375 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 25,
375 ÷ 25
_______ = 15/4
100 ÷ 25
Simplify the improper fraction,
=3 3/4
In conclusion,
3.75=3 3/4
