Answer:
A = 6x² - 10x
Step-by-step explanation:
A = lw
Given:
l = 3x - 5
w = 2x
Work:
A = lw
A = (3x - 5)(2x)
A = 6x² - 10x
2) Two angles in a triangle are 30 degrees and 40 degrees. Find the missing angle measure. Please show your math work step by step and don’t forget the unit.
there's a triangle with 40° on the top left corner with with a line on the edge and a 30° on the bottom right you need to find the missing angle for the bottom left
please help giving out 30 points please show ur work thank u <3
Answer:
Below
Step-by-step explanation:
The answer would be 90°
We know that every triangle should add up to 180°,
with that we can solve it!
30° + 40° = 70°!
180° - 70° = 90°!
30° + 40° + 90° = 180°
70° + 90° = 180°

What is the average rate of change for this function for the interval x=2 to x=4?
Answer:
12
Step-by-step explanation:
The average rate of change in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 2, 4 ]
f(b) = f)4) = 32 ← from table
f(a) = f(2) = 8 ← from table
Then average rate of change is
[tex]\frac{32-8}{4-2}[/tex] = [tex]\frac{24}{2}[/tex] = 12

In an ecosystem some animals get energy by eating plants an leek can eat 20 pounds of plants each day write and evaluate an expression to find how many pounds of plants a herd of 18 elk can eat in one week.
Answer:2520 pounds can be eaten by a herd of 18 elk in one week.
Step-by-step explanation:
Given: A elk an eat 20 pounds of plants in one day .
Now , Quantity of plants eaten by a herd of elk = (Quantity of plants eaten per day) x (Number of elks ) x (Number of days)
So, the quantity of plants a herd of 18 elk can eat in one week = 20 x 18 x 7 [1 week = 7 days]
= 2520 pounds
Hence, 2520 pounds can be eaten by a herd of 18 elk in one week.

Step-by-step explanation:
A cylinder has a height of 4 inches and a diameter of 18 inches. Which equation can be used to find the total surface area of the cylinder in square inches?
A-S=2π(9) + π(9)´2
B-S=π(9)´2 (4)
C-S=2π(9)(4) + 2π(9)´2
D-S=π(9)(4) + π(9)´2
The equation to find the total surface area of the cylinder is S = 2π(9)(h) + 2π(9)².
As per the question, the diameter of the cylinder is given as 18 inches, so we can calculate the radius (r) by dividing the diameter by 2:
r = 18 inches / 2 = 9 inches
The height of the cylinder is given as 4 inches.
To find the total surface area of a cylinder, we can use the following equation:
Total Surface Area = 2πrh + 2πr²
Now we can substitute the values into the equation to find the total surface area:
S = 2π(9)(h) + 2π(9)²
Therefore, the required equation is S = 2π(9)(h) + 2π(9)².

Step-by-step explanation:
The triangles are similar, so ...
EG/EF = DH/DF
EG = m = EF(DH/DF) = (10 yd)(12/15)
m = 8 yd
Find the area of this parallelogram. Be sure to include the correct unit in your answer. 8 in, 15 in, and 6 in
Answer:
90 in²
Step-by-step explanation:
The diagram isn't attached :
However, taking the base of the parallelogram, b as 15 in
The height as 6 in
And the Slant height as 8 in
The Area of a parallelogram is given as :
Area, A = Base, b multiplied by height, h
A = b * h
Hence, Area of the above parallelogram is:
A = 15 in * 6 in
A = 90 in²

Answer:
44
Step-by-step explanation:
since this is a right triangle it must add up to 90 so 32+14 is 46
90-46=44
therefore the unknown factor is 44.

A triangle has congruent angles. Two of the angles measure 68° and 56°. How many degrees are in the third angle?
A. 68
B. 18
C. 56
D. not enough information
Answer:
C. 56
Step-by-step explanation:
So if the total amount of degrees in a triangle is 180
(degrees = 180(n-2), d = 180(3-2), d = 180), then 180 = 68 + 56 + x
solve the equation for x
180 = 68 + 56 + x
180 - 68 - 56 = x
x = 56

Step-by-step explanation:
A translation 4 units to the right and 6 units down means that all of the x values increase by 4 and all of the y values decrease by 6.
Adding 4 to all of the x values and subtracting 6 from all of the y values gives us the coordinates:

If the volume of the cylinder is 3000i * n ^ 3 what is the height of the cylinder ? Use 3.14 for and round the answer to the nearest hundredth . r = 10in The length of height=\ in
Answer:
9.55 in
Step-by-step explanation:
First of all we have to find the base area
base area = radius^2 x 3.14 = 10^2 x 3,14 = 100 x 3,14 =314 in^2
the volume of a cylinder is
V = base area x height
so the height is
V/base area
3000 : 314 = 9.55 in

1. The width of a rectangle is 4 feet, and the diagonal length of the rectangle is 13 feet.
Which measurement is closest to the length of this rectangle in feet?
A)9ft
B)17ft
C)12.4ft
D)13.6ft
Answer:
12.4 ft
Step-by-step explanation:
Use the Pythagorean Theorem to find the length of the diagonal of the rectangle:
(4 ft)² + x² = (13 ft)², or 16 + x² = 169 ft²
Then x² = (169 - 16) ft², and x = +√(153 ft²) = 12.4 ft
(This matches Answer C)
