ABCD is a parallelogram. Find the values of x and y. Solve for the value of z, if z= x-y.
Answers
Answer:
D. 20
Step-by-step explanation:
since the given shape is a parallelogram the parallel sides' length must be equal:
2x-10 = x+30
2x-x = 30+10
x = 40
2y-10 = y+10
2y-y = 10+10
y = 20
since z = x - y
z = 40-20
z = 20

The net of a rectangular prism is shown below. What is the total surface area of this prism
Answers
Answer:
142 cm^2
Step-by-step explanation:
Okay, we can first break this down into 3 different rectangles.
3 x 5 rectangle
16 x 7 rectangle
3 x 5 rectangle.
From here, we just multiply these out and add them. 15 + 15 + 112 = 142. So our answer is 142 cm^2
Answer:
142 cm²
Explanation:
to find the surface area, you need to find the area of all of the boxes within the image above add them all together.
Starting in the middle row and working from left to right it is,
7×3+7×5+7×3+7×5
21+35+21+35=112
Than the bottom and top box is
3×5+5×3
15+15=30
Than you add both of them together,
112+30=142

=> X^2-X-56=0
Factorizing the above equation,
=> X^2–8X+7X-56=0
X(X-8)+7(X-8)=0
(X-8)(X+7)=0
X=8 or -7

Step-by-step explanation:
1. m∠4 + m∠6 = 180
Reason: m∠4 = 120 & m∠6 = 60. 120 + 60 = 180
2. m∠4 + m∠5 = 180
Reason: m∠4 = 120 & m∠5 = 60. 120 + 60 = 180
3. m∠4 + m∠5 = 180 = m∠4 + m∠6
Reason: m∠4 = 120. m∠5 & m∠6 = 60. 120 + 60 = 180
4. m∠4 = m∠4
Reason: 120 = 120. No difference between
•••••••••••••••••••••••••••••••••••••••••••••••••••
m∠5 = m∠6
Reason: the type of triangle that we’re looking at is a equilateral triangle meaning all angle measures measure the exact same thing. If one measure measures 60, the other measure measures 60.
m∠4 + m∠6 = 180
Reason: m∠4 = 120 & m∠6 = 60. 120 + 60 = 180
The average monthly rainfall for 6 months was 28.5 mm. If it had rained 1mm more each month what would the average have been? By how much would the total have been increased in six months and by how much would average have been increased per month? What's the answer??
Answers
Answer:
29.5 mm
Step-by-step explanation:
We are told that the average monthly rainfall for 6 months was 28.5 mm.
Thus, total for the 6 months = 28.5 × 6 = 171 mm
Now, we are told that it rained 1 mm extra each month.
So extra for the six months = 1 × 6 = 6mm
New total for 6 months = 171 + 6 = 177 mm
So, new average for 6 months = 177/6 = 29.5 mm
A baby weighs 100 ounces. Find the baby's weight in pounds and ounces.
Answers
Work Shown:
1 pound = 16 ounces
100/16 = 6.25
100 ounces = 6.25 pounds
100 ounces = 6 pounds + 0.25 pounds
-------
1 pound = 16 ounces
0.25*1 pound = 0.25*16 ounces
0.25 pounds = 4 ounces
------
100 ounces = 6 pounds + 0.25 pounds
100 ounces = 6 pounds + 4 ounces
100 ounces = 6 pounds, 4 ounces

What is the value of x in the equation 3x.. by y 18, when y27
Answers
Answer:
x = 15
Step-by-step explanation:
We need to find the value of x in the equation 3x – y = 18 when y = 27.
To find the value of x, put y = 27 in the above equation.
So,
3x - 27 = 18
3x = 45
x = 15
So, the value of x is 15.

Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope / gradient
c is the y intercept
a).y = 3x + 7
Comparing this equation with the general form above
Gradient of the line = 3
b).2y - 6x = 8
Divide both sides by 2
We have
y - 3x = 8
To make y the subject move 3x to the right side of the equation
That's
y = 3x + 8
Comparing with the general form above that's y = mx + c
The gradient = 3
c).y = 3x + 7
A(2 , y ) , B( x , 4)
Since they lie on the line we can substitute their values into the equation to find the missing points
For A(2 ,y)
We have
y = 3(2) + 7
y = 6 + 7
y = 13For B( x , 4)

3x = 4 - 7
3x = - 3

Write a real-life problem that you can solve using a 45 degree, -45 degree, -90 degree triangle with an 18-ft hypotenuse. Describe your solution
Answers
Answer:
A triangle with angles:
"45°, 45°, 90°"
Is a triangle rectangle, with two catheti of equal length.
Now, there is a lot of problems that you can solve with this:
"Suppose that you want to find the height at which you need to attach a wire in a tree, such that the distance between the tree and the ground is 18ft, and the distance between the base of the tree and the two points where the wire is fixed is exactly the same"
Well, here we have a triangle rectangle with a hypotenuse of 18 ft, with cathetus of equal length (the catheti are the tree and the distance between the base of the tree and the point where the wire is attached at the ground)
And because the catheti are equal, then the angles are 45°, 45° and 90°.

What is the measure of angle X?
Answers
====================================================
Explanation:
Focus on triangle BDH
Interior angles B and D are given to be 40 and 31 respectively. Interior angle H is unknown
For any triangle, the interior angles always add to 180
B+D+H = 180
40+31+H = 180
H+71 = 180
H = 180-71
H = 109
Interior angle H is 109 degrees for triangle BDH
The exterior angle is 180 minus this measure
exterior angle = 180 - (interior angle)
exterior angle = 180 - 109
exterior angle = 71
Note how this is the sum of interior angles B and D, so you could use the remote interior angle theorem here.
