Answer:
h = 3.6
Step-by-step explanation:
This is just substituting in for variables and solving for x. The hard part is knowing the formula.
R = h((a+b)/2) where a and b are the 2 different bases, h is the height or latitude, and R is the area of a trapezoid, is the formula.
Given that R = 8.1, a = 1 and b = 3.5, we can substitute these equations in the formula.
(8.1) = h(((1) + (3.5)) / 2)
= h((4.5) / 2)
= h(2.25)
8.1/2.25 = h
3.6 = h

X= 164, -8, 4, 164
Y= -99, -60, -57, -17
Which equation represents the same relationship?
A. y + 17= 1/4(x - 164)
B. y - 17= 1/4(x + 164)
C. y + 164= 1/4(x - 17)
D. y - 164= 1/4(x + 17)
Answers
The Equation of line is y + 17= 1/4(x - 164).
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
X= 164, -8, 4, 164
Y= -99, -60, -57, -17
Using slope
= ( -17 + 57 )/ ( 164 - 4)
= 40/ (160)
= 1/4
So, Slope- intercept form
y + 17 = /4 ( x- 164)

Variables x, y, and z are integers such that xyz > 0. If xy=30, x/z=2/3, and z=9, what is the value of y?
Answers
Explanation:
Plug z = 9 into the second equation and solve for x.
x/z = 2/3
x/9 = 2/3
x = 9*(2/3)
x = 18/3
x = 6
This leads to
xy = 30
y = 30/x
y = 30/6
y = 5

Angles 1 and 2 are a supplementary pair with the measure of angle 2 being six more than twice the measure of angle 1. What is the measure of angle 2?
Answers
Answer:
58° and 122°
Step-by-step explanation:
Let the 1st angle be 'a'.
2nd angle = 6 more than twice of a = 2a + 6.
Supplementary angles add upto 180°.
=> a + (2a + 6) = 180
=> a + 2a + 6 = 180
=> 3a + 6 = 180
=> 3a = 174
=> a= 174/3 = 58
Thus, angles are:
a = 58°.
2a + 6 = 2(58°) + 6 = 122°

A)m^2-mn+n^2
B)c^2-2cd+d^2
C)16x^2 + 9y^2
D)a^2+b^2
Answers
c^2-2cd+d^2 = (c-d)^2
We can verify this with the following steps
(c-d)^2 = (c-d)(c-d)
(c-d)^2 = c(c-d) - d(c-d)
(c-d)^2 = c^2-cd-cd+d^2
(c-d)^2 = c^2-2cd+d^2

Equation 1: 3 multiplied by 3 is 9. 9 divided by 2 is 4.5
Equation 2: 3 multiplied by 2 is 6. 6 divided by 3 is 2
Equation 1 yields a greater value.
Answer:
The 3x3/2 is greater than 3x2/3
Step-by-step explanation:
Here is a simple tip when solving these questions:
Decimal form is always great to use because you get the answer instantly instead of finding a common denominator while involving fractions.
Let's solve 3x3/2.
First, do 3x3 which is 9.
Your problem should be 9/2
Now, you could do this as a mixed number but like I said there shall be more work so you should do 9/2 on a calculator or divide but involve decimal point if you have a remainder.
9 divided by 2 is 4.5
9/2 is 4.5 (Above is the interpretation in words)
Next, do 3x2/3
The same thing as last, do 3x2 first.
Your problem should be 6/3
If we know our division facts then 6 divided by 3 is 2.
Lastly, compare our numbers.
The 3x3/2 is 4.5 and the 3x2/3 is 2
Line the numbers up:
4.5
2.0
The tens digit clearly shows that 4 is greater than 2.
Therefore,
The 3x3/2 is greater than 3x2/3
