The volume of the rectangular prism will increase by 33% if the width, length, and height are each increased by 10%.
Every three-dimensional object occupies some space. This space is measured in terms of its volume. Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.
The formula for the volume of a rectangular prism is:
V = l x w x h
where
“l” is the base length
“w” is the base width
“h” is the height of the prism
If the width, length, and height are each increased by 10%, the equation will now become:
[tex]V_{2}= 1.10 l * 1.10 w*1.10h[/tex]
[tex]V_{2}= 1.331* l*w*h[/tex] V = l*w*h
[tex]V_{2}= 1.331* V[/tex]
Hence, if the width, length, and height are each increased by 10%, the volume of the rectangular prism will increase by 33%.

Step-by-step explanation:

Answer:
x = 7, x = 10
Step-by-step explanation:
x² + 70 = 17x ( subtract 17x from both sides )
x² - 17x + 70 = 0 ← in standard form
consider the factors of the constant term (+ 70) which sum to give the coefficient of the x- term (- 17)
the factors are - 10 and - 7 , since
- 10 × - 7 = + 70 and - 10 - 7 = - 17 , then
(x - 10)(x - 7) = 0 ← in factored form
equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x - 10 = 0 ⇒ x = 10
Evaluate.

Step-by-step explanation:
First start by raising all the numbers to the power indicated:
5^4 = 625
8^5 = 32768
2^9 = 512
5^2 = 25
Then divide the numerators by the denominators:
625 / 8 = 78.125
32768 / 64 = 512
512 / 25 = 20.48

What is a scale factor?A scale factor is a ratio between the scale of the original object in an actual sense and the prototype figure of the same object.
We have
The height of the plane in scale drawing:

answer to the nearest tenth.
4x
6x - 6
Answer:
Circumference = 75.4
Step-by-step explanation:
Since the circles are identical, that means that the radii must be equal.
4x=3x+3
x=3
That means that radius = 12
The formula for the circumference = 2pi × radius
2pi × 12 = 24pi ≈ 75.4
Answer:
75.4 (nearest tenth)
Step-by-step explanation:
The diameter of a circle is the distance from one side of the circle to the other through the center. The diameter is the widest part of the circle.
The radius of a circle is the distance from the center to the circumference. The radius is half the diameter of a circle.
We have been given the radius of the circle on the left: r = 4x.
Therefore, as the diameter is twice the radius, the diameter of the circle on the left is: d = 2(4x) = 8x
We have been given the diameter of the circle on the right: d = 6x + 6
Equate the two diameters and solve for x:
⇒ 8x = 6x + 6
⇒ 8x - 6x = 6x + 6 - 6x
⇒ 2x = 6
⇒ 2x ÷ 2 = 6 ÷ 2
⇒ x = 3
Substitute the found value of x into one of the diameter expressions to find the diameter of both circles:
⇒ d = 8x
⇒ d = 8(3)
⇒ d = 24
Circumference of a circle
C = πd
(where d is the diameter)
Substitute the found diameter into the circumference formula:
⇒ C = πd
⇒ C = 24π
⇒ C = 75.39822...
⇒ C = 75.4 (nearest tenth)
Therefore, the circumference of each circle is 75.4 units (nearest tenth).

mav is older than justin. Their ages are consecutive integers find mavs age if the product of their age is 42
Answer:
7
Step-by-step explanation:
hope this works :)
consecutive numbers means 2 numbers next to eachother like 8 and 9 or 3 and 4
product means basically the result of numbers multiplying together, e.g. the product of 8×9 = 72
so if you use trial and error you will find 6 × 7 = 42 and since mav is older she must be 7 years old
Answer:
mav is 7
Step-by-step explanation:
let justin's age be n then mav is n + 1 and the product is
n(n + 1) = 42
n² + n = 42 ( subtract 42 from both sides )
n² + n - 42 = 0 ← in standard form
(n + 7)(n - 6) = 0 ← in factored form
equate both factors to zero and solve for n
n + 7 = 0 ⇒ n = - 7
n - 6 = 0 ⇒ n = 6
since n > 0 then n = 6
mav is n + 1 = 6 + 1 = 7

write the equation for a parabola with a focus at (6,-4)(6,−4)left parenthesis, 6, comma, minus, 4, right parenthesis and a directrix at y
The equation of the parabola is (x - 6)² = 6(y + 5.5).
Given that, a focus at (6,-4) and a directrix at y= -7.
We need to find the equation for a parabola.
What are focus and directrix?Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).
The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where
The vertex of the parabola is (h , k)
The focus is (h, k + p)
The directrix is at y = k - p
∵ The focus of the parabola is at (6, -4)
The coordinates of the focus are (h, k + p)
∴ h = 6
∴ k + p = -4 ⇒ (1)
∵ The directrix of the parabola is at y = -7
The directrix is at y = k - p
∴ k - p = -7 ⇒ (2)
Solve the system of equations to find k and p
Add equations (1) and (2) to eliminate p
∴ 2k = -11
Divide both sides
∴ k = -5.5
Substitute the value of k in equation (1) to find p
∵ -5.5 + p = -4
Add 5.5. to both sides
∴ p = 1.5
∵ The form of the equation is (x - h)² = 4p(y - k)
Substitute the values of h, k, and p in the form
∴ (x - 6)² = 4(1.5)(y - -5.5)
∴ (x - 6)² = 6(y + 5.5)
Therefore, the equation of the parabola is (x - 6)² = 6(y + 5.5).

4x = 0.5(2x- 12) solve for x
Answer: x = -2
Step-by-step explanation:
4x=0.5(2x−12)
Use the distributive property to multiply 0.5 by 2x−12.
4x=x−6
Subtract x from both sides.
4x−x=−6
Combine 4x and −x to get 3x.
3x=−6
Divide both sides by 3.
x= 3−6

For the equations 7 x - y = 7 and x + 2 y = 6, we get the solution as x = 4 / 3 and y = 7 / 3.
We are given the equations:
7 x - y = 7 … (1)
x + 2 y = 6
x = 6 - 2 y … (2)
Substitute equation (2) in equation (1), we get that:
7 ( 6 - 2 y ) - y = 7
42 - 14 y - y = 7
15 y = 35
y = 35 / 15
y = 7 / 3
x = 6 - 2 ( 7 / 3)
x = 18 - 14 / 3

Answer should be rounded to the nearest WHOLE NUMBER
The total number of people in the food court eating pizza, burritos, and hamburgers is 113 (Approximate) or (Whole number)
People eating hamburger P(h) =0.38
People eating burritos P(b) = 0.31
Number of people eating pizza = 35
Let's suppose the total number of people is 1
So,
By adding the total number of people eating hamburgers and burritos
= 0.38+0.31
= 0.69
The ratio of the total number of people eating pizza = 1.00 - 0.69
= 0.31
So total number of people eating pizza = 0.31 = 35
By solving :
1 = 35 / 0.31
= (35*100)/31
= 3500/31
= 112.9 (we have to write it down in the nearest whole number)

In a triangle:
The shortest side is opposite the smallest angle.The longest side is opposite the biggest angle.When labeling angles and sides of triangles, it is convention to label the side opposite an angle with the same letter but in lower case.
Therefore in ∆JLK:
Side j is opposite angle J.Side l is opposite angle L.Side k is opposite angle K.As 16 < 73 < 91
