Answer:
Step-by-step explanation:
Set up a proportion
15 Liters / 4 gallons = 210 Liters / x Cross Multiply
15x = 4 * 210 Combine the right
15x = 840 Divide by 15
x = 840 / 15
x = 56 gallons
determine the size of V
Answer:
Size of V = 95°
Step-by-step explanation:
The total sum of angles in a triangle is 180°
You can find Angles T and V.
2x+3x+5 = 180°-25°
5x+5 = 155°
5x = 155°-5
= 150°
x = 150°÷5
= 30°
Angle V = 3×30°+5
= 95°

MAQ Unit 4: Parallel and Perpendicular Lines Assessment 8. Acub cut for wheelchairs must meet ADA (Americans with Disabilities Act requirements. Find the measure of 21 (exterior to the triangle) in the diagram below. 78° 1
Answer:
168
Step-by-step explanation:
- first we need to find the third angle of the triangle, and since 180 is the sum of all angles, 180 - 90 - 78 = 12
- 12 is the interior angle at point 1, the exterior angle is 180 - 12 = 168
(here we use 180 because its a straight line)
The measure of 21 (exterior to the triangle) is 168 degrees.
The calculation is as follows:
The third angle for the triangle is= 180 - 90 -78
= 12
Now the exterior angle should be= 180 - 12
= 168
Therefore we can conclude that the measure of 21 (exterior to the triangle) is 168 degrees.

If the length of the base of a triangle is
increased by 10 percent and the height is
decreased by 20 percent, what is the
percent decrease in the area of the
triangle?
(A) 6%
(B) 8%
(C) 10%
(D) 12%
Answer:
d
Step-by-step explanation:
the answer is 12% decrease in area
The required, percentage decrease in the area of the triangle is 12%. Option D is correct.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Area of the triangle = 1/2bh
Now,
The length of the base of a triangle is increased by 10 percent and the height is decreased by 20 percent,
base = b + 0.1b = 1.1b
height = h - 0.2h = 0.8h
New area = 1/2[1.1b][0.8h] = 0.88 [1/2b/h]
Percentage decrease in area = [ 1/2bh - 0.88 [1/2b/h] / 1/2bh × 100%
= 12%
Thus, the required, percentage decrease in the area of the triangle is 12%. Option D is correct.

Find the volume of the tetrahedron with the given vertices. (2, 0, 0), (0, 4, 0), (0, 0, 4), (2, 4, 4)
Answer:
The volume of the tetrahedron is
[tex]\frac{-32}{3}[/tex]
Step-by-step explanation:
To find the volume of a tetrahedron with vertices (2, 0, 0), (0, 4, 0), (0, 0, 4), (2, 4, 4).
We know by definition that the volume of a tetrahedron with vertices [tex](x_{1}, y_{1}, z_{1}), (x_{2}, y_{2}, z_{2}), (x_{3}, y_{3}, z_{3})[/tex] is
[tex]\frac{1}{6}\begin{vmatrix}
2 & 0 & 0 & 1\\
0 & 4 & 0 & 1\\
0 & 0 & 4 & 1\\
2 & 4 & 4 & 1
\end{vmatrix}[/tex]
From here we have:
[tex]\frac{1}{6}\begin{vmatrix}
x_1 & y_1 & z_1 & 1\\
x_2 & y_2 & y_2 & 1\\
x_3 & y_3 & z_3 & 1\\
x_4 & y_4 & y_4 & 1
\end{vmatrix}[/tex]
Finding the determinant of that matrix we have:
[tex]\frac{1}{6} (-64)[/tex] = [tex]\frac{-32}{3}[/tex]

A) 20
B) 10
C) 30
D) 40
don't guess. I'll give you brainly.
Answer:
Hey buddy, here is your answer. Hope it helps u

The area of a rectangular wall of a barm is 140
Square feet. its length is 6 feet longer than twice its
width. Find the length and width of the wall of the barn.
Answer:
length = 20 feet
width = 7 feet
Step-by-step explanation:
This problem can be solved using a system of equations. Using the given information, you can formulate 2 equations:
l*w = 140
l = 2w + 6
In order to solve this system of equations, you can use the Substitution Property of equality to substitute the l in the first equation for (2w + 6) in order to find the width:
where l*w = 140 and l = 2w + 6,
1. (2w + 6)*w = 140
2. 2w^2 + 6w = 140
3. w^2 + 3w = 70
4. w^2 + 3w - 70 = 0
5. (w - 7) (w + 10) = 0
6. w = 7, -10
1. Substitution
2. Simplification
3. Divide both sides by 2
4. Subtract 70 from both sides
5. Factor the left side (find 2 numbers that add to 3 and multiply to -70)
6. Solve for w
The width must be 7 because a width of -10 is impossible. Now, you just need to plug that into the equation to solve for l:
l*w = 140
7l = 140
l = 20
That means that the length is 20 and the width is 7.

In △ABD, altitude AC¯¯¯¯¯ intersects the right angle of triangle ABD at vertex A. BC=3.1 in. and CD=7.2 in..
What is the length of AC¯¯¯¯¯?
Enter your answer in the box. Round your final answer to the nearest hundredth.
Answer:
4.72 in.
Step-by-step explanation:
BC = 3.1 in.
CD = 7.2 in.
Altitude of right triangle altitude is given as [tex] h = \sqrt{xy} [/tex], where:
h = altitude
x = 3.1 in.
y = 7.2 in.
Plug in the values into the formula
[tex] h = \sqrt{3.1*7.2} [/tex]
[tex] h = \sqrt{22.32} [/tex]
[tex] h = 4.72 in. [/tex] (nearest hundred)
Answer:
4.72

A 2,100-square-foot home in Cheyenne, WY , costs $110 per square foot. How much does this home cost? (Do not enter anything but numbers for the answer or it will count it wrong. Follow directions please because I am not coming back to grade if you mess up)
$231,000.
Step-by-step explanation:We have been given that a 2,100 square foot home in Cheyenne Wyoming costs $110 per square feet.
To find the total cost of home we will multiply the total area of home by the cost of per square feet area.
The total cost of home:2,100 × 110 = 231,000$
