What is a rectangular prism?A closed solid with two parallel rectangular bases joined by a rectangle surface is known as a rectangular prism.
A rectangular box has a length of √90 inches, a width of √14 inches, and a height of √70 inches.
The volume of the box is given as,
V = LBW
V = (√90) x (√14) x (√70)
V = 296.98 cubic inches
The area of the top of the box is given as,
SA = 2(LW + WB + BL)
SA = 2(√90 x √14 + √14 x √70 + √70 x √90)
SA = 292.35 square inches
The ratio of the height of the box to the length of the box is given as,

What is the best way to show that the side lengths 8 feet, 16 feet, and 22 feet do NOT form a right triangle?The best way to show that the side lengths 8 feet, 16 feet, and 22 feet do not form a right triangle is to substitute these values into the Pythagorean theorem and show that a false statement results.The Pythagorean theorem states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side.In this case, 8^2 + 16^2 = 64 + 256 = 320, which does not equal 22^2 = 484.This disproves the possibility of the triangle being a right triangle. As an alternative, one could also determine the sum of the side lengths and compare it to the Pythagorean theorem.In this case, the sum of the side lengths is 8 + 16 + 22 = 46, which again does not equal the square of the longest side.Both these methods show that the side lengths 8 feet, 16 feet, and 22 feet do not form a right triangle.To learn more about Pythagorean theorem refer to:

A banker loaned $5000 to one cutomer and $8000 to another. If the annual interet on the econd loan i %2 higher than the firt and the combined annual interet i $810, What i the interet rate for each loan?
The interest rate for first loan is 5% and for the second loan is 7%.
The amount of first loan = $5000
Let the rate of interest for first loan = r
The interest from first loan = ($5000 × r)/100
= 50 r
The amount of second loan = $5000
Let the rate of interest for second loan = r+2
The interest from first loan = ($8000 × (r+2))/100
= 80 r + 160
Total interest = 50 r + 80 r + 160
= 130 r + 160
As per the question statement combined annual interest = $810
810 = 130 r + 160
r = (810-160)/130
r = 5%
Rate of second loan = r+2 = 5+2

A relation is plotted as a linear function on the coordinate plane starting at point E at(0, 27)and ending at point F at (5, −8).
What is the rate of change for the linear function and what is its initial value?
Select from the drop-down menus to correctly complete the statements.
The rate of change for a linear function, also known as the slope, can be found by calculating the change in the y-coordinate (rise) divided by the change in the x-coordinate (run) between two points on the line. The slope of a line describes how steep the line is and whether it is increasing or decreasing.
In this case, the slope of the linear function can be found by using the coordinates of points E and F:
Slope = (y2 - y1) / (x2 - x1)
Slope = (-8 - 27) / (5 - 0)
Slope = -35/5
The slope of the linear function is -35/5 or -7.
The initial value of a linear function is the y-intercept, which is the point where the line crosses the y-axis. To find the y-intercept, we can use the slope and one point on the line (in this case point E (0,27)):
y = mx + b
27 = -7(0) + b
b = 27
The y-intercept of the linear function is 27.
So, the linear function starts at point E (0,27) with an initial value of 27, and has a rate of change or slope of -7.
Figure 3 of a tile pattern has 11 tiles, while figure 4 has 13 tiles The patter grows at a constant rate.

B which figure will contain 1015 tiles
Answer:
y = 2x + 5
Figure 505
Step-by-step explanation:
(3,11) ( 4,13)
Find the slope
Change in y over the change in x
[tex]\frac{13-11}{4-3}[/tex] = [tex]\frac{2}{1}[/tex] = 2
slope (m) is 2.
Part A
Find the y -intercept
m = 2
x = 3 from the point (3,11)
y = 11 from the point (3,11)
y = mx + b Substitute what I know and solve for b
11 = (2)(3) + b
11 = 6 + b Subtract 6 from both sides
11 - 6 = 6 -6 + b
5 = b
The y intercept (b) is 5
y = mx + b
y = 2x + 5
Part B
y = 2x + 5
1015 = 2x + 5 Subtract 5 from both sides
1015 - 5 = 2x + 5 - 5
1010 = 2x Divide both sides by 2

An equation that can be used to determine the number of hours, h, that Moira needs to read to finish the book is h + 178 = 214.
How to write an equation to model this situation?In order to write an equation that model this situation, we would assign a variable to the number of hours that is needed to read to finish the book and the total number of hours respectively, and then translate the word problem into algebraic equation as follows:
Let the variable h represent the number of hours.Let the variable T represent the total number of hours.Next, we would translate the word problem into an algebraic equation based on the fact that she read for 178 hours yesterday as follows;
h + 178 = T

What is the value of exponential 2?
The value of exponential 2 is 2^2, or 4. This means two multiplied by itself two times or squared.
Exponential notation is a way of expressing a number, usually greater than 10, as a base number, the number 2 in this case, raised to a power, which in this case is 2. Therefore, exponential 2 is written as 2^2, which means two multiplied by itself two times or squared.
For example, if we wanted to find the value of exponential 8, we could easily calculate 2^8, or 256, which is much faster than multiplying 2 by itself 8 times. Exponential notation is also helpful when calculating exponents with variables.
For example, if we wanted to find the value of 3^x, we could use exponential notation to find the answer quickly. In summary, exponential notation is a useful tool for quickly finding the value of a number raised to a power.

Cost is equal to Selling price plus Loss ( when selling price and loss is given )Therefore, the cost price (C.P.) is 350.
Find the C.P ?Cost is the same as the selling price plus the loss ( when selling price and loss is given ).
The Profit and Loss Percentage Formula
Profitability (P%) is calculated as (Profit /Cost Price) / 100.
Loss percentage (L%) Equals 100 divided by (Loss / Cost price).
S.P. = {(100 + P%)/100}
if SP > CP, then CP
If SP > CP, S.P. = (100 - L%)/100 CP
C.P. = {100/(100 + P%)}
if SP > CP, then SP
C.P. = SP (if SP > CP)/100/(100 - L%)
Loss percent = 10%
To find:
The C.P.
Solution:
Let x be the C.P.
We have,
S.P. = 315
Loss percent = 10%
S.P = C.P - 10% 0f C.P
315 = X- 0.1X

whats the equation of the line in slope-intercept form
The equation in slope intercept form is
y = 5/2x + 5
What is Slope intercept form ?One of the most popular ways to describe a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula may be used to get the equation of a line ( the y-coordinate of the point where the line intersects the y-axis). The equation of a line is the equation that each point on the line fulfills.
The slope intercept form is a technique for figuring out a straight line's equation in the coordinate plane. Any point's coordinates on a straight line must fulfill a certain relation, which is known as the equation of a straight line.
Any location that is not on the line will not fulfill the coordinates.
This equation's solution is simple to find. A straight line's slope, or angle of inclination from the x-axis, and the intercept it makes with the y-axis are both necessary to determine the slope intercept form of the line.
Two points on the line are (-2,0) and (0,5)
The slope intercept form is
y = mx + c
so when y = 0 and x = -2
0 = -2(m) + c
or, 2m -c = 0 ..(i)
again when x= 0 y = 5
5 = 0*m + c
c = 5
so putting c= 5 in equation (i) we get
m = 5/2
so the equation in slope intercept form is
y = 5/2x + 5

Answer:
area of shaded region = 119 cm²
Step-by-step explanation:
the outer figure has one pair of parallel sides and is a trapezium.
the shaded area (A) is calculated as
A = area of trapezium - area of white triangle
the area of a trapezium is calculated as
area = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height between the bases b₁ and b₂
here h = 14 , b₁ = 9 , b₂ = 17 , then
area = [tex]\frac{1}{2}[/tex] × 14 × (9 + 17) = 7 × 26 = 182 cm²
the area of the triangle is calculated as
area = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
here b = 9 and h = 14 , then
area = [tex]\frac{1}{2}[/tex] × 9 × 14 = 4.5 × 14 = 63 cm²
then area of shaded region (A) is
A = 182 - 63 = 119 cm²
