Step-by-step explanation:
There is a two-digit number x. 47 divided by x gives a remainder of 5, 91
divided by x gives a remainder of 7 and 132 divided by x gives a remainder of 6.
Find x.
Answer:
x = 21 or x = 42Step-by-step explanation:
Given
47 = mx + 5 ⇒ mx = 4291 = nx + 7 ⇒ nx = 84132 = kx + 6 ⇒ kx = 126As we see, the number x is factor of 42, 84 and 126. The two-digit factors are:
42 = 1*42 = 2*2184 = 2*42 = 4*21126 = 3*42 = 6*21We have two possible solutions:
21 and 42Proof:
47/21 = 2 rem 5, 47/42 = 1 rem 591/21 = 4 rem 7, 91/42 = 2 rem 7132/21 = 6 rem 6, 132/42 = 3 rem 6Help i really don’t get it and I need it for my test help me please and thank you

where the area of the base is 6.8\text{ m}^26.8 m 2 and the height of the pyramid is 8.6\text{ m}8.6 m. Round your answer to the nearest tenth of a cubic meter.
r = radius h = height s = slant height V = volume L = lateral surface area B = base surface area A = total surface area π = pi = 3.14159 √ = square root
The Volume of pyramid is 19.5 [tex]m^{3}[/tex].
What is pyramid?A pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apx. Each base edge and apx form a triangle, called a lateral face.
What is volume of pyramid?The volume of a pyramid refers to the space enclosed between its faces.
Volume of pyramid = (1/3) (Base area * height of pyramid )
According to the question
Area of the base = 6.8 [tex]m^{2}[/tex]
Height of the pyramid = 8.6 m
now,
using the formula of Volume of pyramid
Volume of pyramid = (1/3) (Base area * height of pyramid )
substituting the values
Volume of pyramid = (1/3) ( 6.8 * 8.6 )
= 19.49 [tex]m^{3}[/tex]
Rounding off to nearest tenth of a cubic meter
Volume of pyramid = 19.5 [tex]m^{3}[/tex]
Hence, the Volume of pyramid is 19.5 [tex]m^{3}[/tex]

an equation is shown below:
5 ( 2x - 8 ) + 15 = -15
write the steps you'll use to solve the equation and explain each step.
Answer: x = 1
Step-by-step explanation:
5 ( 2x - 8 ) + 15 = -15 (write the equation)
5 ( 2x - 8 ) = -30 (subtract by 15 on both sides)
2x - 8 = -6 (divide by 5 on both sides)
2x = 2 (add 8 to both sides)
x = 1 (divide by 2 on both sides)

Skills needed: One-Variable Equations, Solving Equations
1) The first thing is to use P.E.M.D.A.S
There are no Parentheses, or Exponents, so we go to multiplication
The quantity we multiply is: [tex]5(2x-8)[/tex]
Using distributive property (which is [tex]a(b+c) = ab+ac[/tex]), you get:
[tex]5(2x-8) = 5(2x) - 5(8) = 10x - 40[/tex]
2) Now, we substitute back in and combine like terms:
[tex]10x-40+15=-15[/tex]
Combine the -40 and 15 ([tex]-40+15=-25[/tex])
Then, you will get: ([tex]10x-25=-15[/tex])
3) Add 25 to both sides, to isolate the variable:
[tex]10x = -15+25[/tex], and then -15+25 is 10, so
[tex]10x = 10[/tex]
4) Divide by 10 on both sides, and get [tex]x = 1[/tex]

Randy rented a rectangular storage shed with the volume of 357 ft does it sheds height is 8 and 1/2 ft and the width of is 6 ft what is the length of the shed
Answer:
7 feets
Step-by-step explanation:
Volume of shed, V = 357 feet³
Height of shed, H= 8 1/2 fts
Width of shed, W = 6 ft
Using the relation :
Volume = Length * width * height
357 = L * 6 ft * 17/2 feets
357 feets³ = L * 51 feets²
L = 357 feets³ / 51 feets²
Length, L = 7 feets
Tyler bought shoes for $72. The next week he noticed that the price went
up to $87. What was the percent increase (percent change)? Round your
answer to the nearest whole percent. *
Answer:
Percent increase is 21%
Step-by-step explanation:
Initial cost of shoes = $72
New price of shoes = $87
Increase in price of shoes = New price of shoes - Initial cost of shoes
= [tex]87-72[/tex]
= $15
Percentage increase in price of shoes = ( Increase in price of shoes ÷ Initial cost of shoes) × 100
= [tex]\frac{15}{72}(100)=20.8\%[/tex]
≈ 21%
So, percent increase is 21%

how to do graphs of quadratic functions
Answer:
The Graph of a Quadratic Function
A quadratic function is a polynomial function of degree 2 which can be written in the general form.
Step-by-step explanation:
Example: Graph: f(x)=−x2−2x+3.
Solution:
Step 1: Determine the y-intercept. To do this, set x=0 and find f(0).
f(x)f(0)===−x2−2x+3−(0)2−2(0)+33
The y-intercept is (0,3).
Step 2: Determine the x-intercepts if any. To do this, set f(x)=0 and solve for x.
f(x)000x+3x======−x2−2x+3−x2−2x+3x2+2x−3(x+3)(x−1)0−3orx−1x==Set f(x)=0.Multiply both sides by −1.Factor.Set each factor equal to zero.01
Here where f(x)=0, we obtain two solutions. Hence, there are two x-intercepts, (−3,0) and (1,0).
Step 3: Determine the vertex. One way to do this is to first use x=−b2a to find the x-value of the vertex and then substitute this value in the function to find the corresponding y-value. In this example, a=−1 and b=−2.
x====−b2a−(−2)2(−1)2−2−1
Substitute −1 into the original function to find the corresponding y-value.
f(x)f(−1)====−x2−2x+3−(−1)2−2(−1)+3−1+2+34
The vertex is (−1,4).
Step 4: Determine extra points so that we have at least five points to plot. Ensure a good sampling on either side of the line of symmetry. In this example, one other point will suffice. Choose x=−2 and find the corresponding y-value.
x −2 y 3f(−2)=−(−2)2−2(−2)+3=−4+4+3=3Point(−2,3)
Our fifth point is (−2,3).
Step 5: Plot the points and sketch the graph. To recap, the points that we have found are
y−intercept:x−intercepts:Vertex:Extra point:(0,3)(−3,0) and (1,0)(−1,4)(−2,3)

Answer:
FV= $10,714.81
Step-by-step explanation:
Giving the following information:
Initial investment= $7,567
Number of periods= 7*4 = 28 quarters
Interest rate= 0.05/4= 0.0125
To calculate the future value, we need to use the following formula:
FV= PV*(1+i)^n
FV= 7,567*(1.0125^28)
FV= $10,714.81
A swimming pool is the shape of a rectangular prisam. If pool is 12 3/4 yards wide and 9 yards deep what is the volume of the swimming pool
Complete question :
A swimming pool is the shape of a right rectangular prism. If the pool is 12 3/4 yards long, 5 2/3 yards wide, and 9 yards deep, what is the volume of the swimming pool
Answer:
650 1/4 yd³
Step-by-step explanation:
Volume of a rectangle prism :
V = Length * width * height
V = 12 3/4 * 5 2/3 * 9
V = 51/4 * 17/3 * 9/1
V = (51*17*9) / (4*3*1)
V = 7803 / 12
V = 650 3/12
Volume of swimming pool = 650 1/4 yd³
