Answer:
BC = 1 6.45
Step-by-step explanation:
The way it is written, BC is the hypotenuse
BC^2 = AB^2 + CA^2 Substitute the numbers for AB and CA
BC^2 = 13.9^2 + 8.8^2 Perform the squares
BC^2 = 193.21 + 77.44 Add the right side
BC^2 = 270.65 Take the square root of both sides
BC = 16.45

Regan's New Year's resolution is to exercise more. Today, she plans to run 1.5 miles on the track around her school's football field. If each lap around the track is 0.25 miles, how many laps should she run?
Answer:
6 laps
Step-by-step explanation:
According to the scenario, calculation of the data are as follows:
Each lap = 0.25 miles
Regan's plan to run= 1.5 miles
So, we can calculate number of laps by using following formula,
Number of laps = Total miles to run ÷ each lap miles
By putting the value, we get
Number of laps = 1.5 miles ÷ 0.25 miles
= 6 laps
So, she should run 6 laps.

What is the missing value in the work shown?
A.

B.
-81
C.
-162
D.
81
Answer:162
Step-by-step explanation:
Missing value in the equation of the storage bin that gives a maximum area is 162.
What is area?
" Area is the surface which represents the space occupied by any two dimensional object."
Formula used
(a -b)² = a² -2ab + b²
According to the question we have ,
A(x) = -2x² +36x
= -2(x²- 18x)
= -2 ( x² - 18x ) + 2 (9)² - 2(9)²
= -2 (x² - 18x + (9)²) + 2 (9)²
= -2 (x -9)² + 162
Hence we conclude that Option A is correct.

5 A triangle has two congruent angles. The length of one
side of the triangle is 16 cm and the length of another
side is 32 cm. Which of the following is the length of
the third side of the triangle?
A. 64 cm
B. 48 cm
C. 32 cm
D. 16 cm
E. It cannot be determined based on the informati
Answer:
Answer: C. 32 cm
Step-by-step explanation:
Triangle Inequality Theorem
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
We know the triangle has two congruent angles, which means the triangle is isosceles, i.e., it has two congruent sides.
We are given two side lengths of 16 cm and 32 cm. The third side must have a length of 16 cm or 32 cm for the triangle to be isosceles.
If the third side had a length of 16 cm then the lengths would be 16-16-32. But that combination cannot form a triangle because of the condition stated above.
If y=16, z=16, and x=32 (the worst possible combination), then the inequality
0 < x < 32
wouldn't be satisfied, thus the third side cannot have a length of 16 cm and it must have a length of 32 cm
Answer: C. 32 cm
We want to find the length of the missing leg of the given triangle. We will see that the correct options are C and D.
Congruent angles:
Two angles are congruent if these have the same measure.
Then if the triangle has two congruent angles it means that the triangle must be an isosceles triangle.
Finding the missing side.We know that one side measures 16cm and the other side measures 32 cm, and this is an isosceles triangle, so it must have two equal sides.
Then the possible measures of the missing side are either 16cm or 32 cm.
So the correct options are C and D.

The width of a rectanle is 8n - 8.5 feet and the lenght is 8.5n + 10 feet. Find the perimeter of the rectangle
Answer:
The perimeter of a rectangle is:
P = 33n+3Step-by-step explanation:
Given
The width of a rectangle w = 8n - 8.5 feet
The length of a rectangle l = 8.5n + 10 feet
To determine
The perimeter of a rectangle = P = ?
The perimeter of a rectangle can be determined using the formula
[tex]P = 2(l+w)[/tex]
substitute l = 8.5n + 10 and w = 8n - 8.5
[tex]P=2\left(8.5n+10+8n-8.5\right)[/tex]
[tex]=2\left(16.5n+10-8.5\right)[/tex]
[tex]=2\left(16.5n+1.5\right)[/tex]

Therefore, the perimeter of a rectangle is:

HELPP
Answer:
X and Y
Step-by-step explanation:
Right triangle: a = 1/2bh
Rectangle: a = lw
Circle: a = pi*r^2
1/2*2*3 = 3
2*3 = 6
pi(1.5^2) = 7.069
Sqrt2^2 = 2
Sqrt2*2Sqrt2 = 4
2+4 = 6
figure "X" and the figure "Y" have the same amount of area.
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given four figures to find the which two figures have the same area.
To calculate the area consider these mini squares to be unit squares.
For the first figure,
area of triangle = 1 /2 * base * height
In our case,
base = 2 unit
height = 3 units
Thus, area = 1/2 * 3 * 2
Area = 3 unit square
For second figure,
area of rectangle = base * height
in our case,
base = 3
height = 2
thus,
area = 3 * 2 = 6 unit squares
For the third figure,
We will separate it into two figures one is rectangle of √2 and 2√2 sides and the other is a square of √2 side.
(Since, diagonal of the Unit square is √2 from the Pythagorean theorem)
Thus,
Area of the "Y" figure = √2 * 2 √2 + (√2)²
Area of the "Y" figure = 4 + 2
Area of the "Y" figure = 6 unit square
For the fourth figure,
Area of circle = pi * radius²
In our case,
radius = 1.5 unit
Thus,
Area = pi * 1.5*1.5
Area = 7.68 unit square
Therefore, figure "X" and the figure "Y" have the same amount of area.
