PLZZZZZZ HLPPPPP MEEEEEEE how could you find the y coordinate of the midpoint of a vertical line segment with endpoints at (0, 0) and (0, -12)?
CHECK ALL THAT APPLY
A. add the endpoints B. divide 12 by 2 C. divide -12 by 2 D. multiply -12 by 2
Answer:
A. Add the endpoints
C. Divide -12 by 2
Step-by-step explanation:
To find the midpoint of the vertical line segment with endpoints (0, 0) and (0, -12).
Step 1: Add the endpoints (y-coordinates)
0+-12=-12
Step 2: Divide -12 by 2
-12/2=-6
Therefore, the y-coordinate of the midpoint of a vertical line segment is -6.
Options A and C are correct.

Violeta wants to install new tiling in her kitchen. She places two triangular tiles together as shown in the following figure. In order to plan her installation, she needs to find the length of BC
Answer:
25
Step-by-step explanation:
To obtain the length of BC, we shall apply the pythagoras theory as show below:
From the diagram above, the pythagoras theory states as follow:
|BD|² = |CD|² + |BC|²
|BD| = 65
|CD| = 60
|BC| = m
|BD|² = |CD|² + |BC|²
65² = 60² + m²
4225 = 3600 + m²
Collect like terms
m² = 4225 – 3600
m² = 625
Take the square root of both side
m = √625
m = 25
|BC| = m = 25
Therefore, the length of BC is 25
An area of 4 square yards is equal to 36 square feet. 10 square yards is equal to how many square feet?
Answer:

Step-by-step explanation:
36 square feet divided by 4 square yards equals to 9 square feet for 1 square yard.
9 square feet times 10 square yards equals to 90 square feet.
Answer:
90 square feet
A tent in the shape of a triangle prism is made using the following piece of fabric.
Find the surface area of the fabric. Explain your reasoning
Answer:
85.84 ft²
Step-by-step explanation:
The surface area of the fabric would be the total net area of the shape of the tent covered.
Thus, surface area = area of the 3 rectangular faces + area of the 2 triangular faces
From the diagram given, the 3 rectangular faces have the same dimensions as follows:
L = 6ft
W = 4ft
Area of the 3 rectangular faces = 3(6*4) = 3(24) = 72ft²
The 2 triangular faces have the same dimensions as follows:
B = 4f
H = 3.46ft
Area of the 2 triangular faces = 2(½*B*H)
= 2(½*4*3.46)
= 2(2*3.46)
= 2(6.92)
= 13.84 ft²
Surface area of fabric used to cover the triangular tent = 72ft² + 13.84ft² = 85.84 ft²

85.84

A mountain climber took 2 minutes to rappel down 60 feet. Which equation shows the correct calculation to show his movement per minute? –60(–2) = 30 –60 ÷ –2 = –30 –60 ÷ 2 = –30 60(–2) = 30
Answer: –60 ÷ 2 = –30
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Speed rate = distance / time
Replacing with the values given:
Speed rate = -60 ft /2 min
The distance is negative because the climber is going down.
So, the correct equation is:
–60 ÷ 2 = –30

The ratio of the same side interior angles of two parallel lines is 1:14. Find the measures of all eight angles formed by the parallel lines and transversal. Need by (at most tmrw but would love if u answered tdy!) Thanks!
Answer:
The measures of all eight angles formed by the parallel lines and transversal are;
The four angles for the one of the parallel line = 12°, 168°, 12°, 168°
The four angles for the other parallel line = 12°, 168°, 12°, 168°
Step-by-step explanation:
The same-side interior angle theorem states that the the sum of the same side interior angles formed by the transversal intersection of two parallel lines is equal to 180°
Whereby the ratio of the angles is 1:14, we have;
Let one of the angles = x
Therefore, the other angle = 14·x
We then have;
x + 14·x = 180°
15·x = 180°
x = 180°/15 = 12°
∴ The other angle = 14×12 = 168°
Hence the four angles on one of the parallel lines are therefore;
12°, 168°, 12°, 168°
Similarly, the four angles on one of the other parallel line are;
12°, 168°, 12°, 168°
The measures of all eight angles formed by the parallel lines and transversal = 12°, 12°, 12°, 12°, 168°, 168°, 168°, 168°.

what are the next terms in the sequences below 19 , 15 , 11 , 7 , 3 , -1 , _
Answer:
The answer is -5.
Step-by-step explanation:
As you look at the first 3 terms, all have the common difference of 4. So the next term after -1 is :
19 - 4 = 15
15 - 4 = 11
11 - 4 = 7
7 - 4 = 3
3 - 4 = - 1
- 1 - 4 = - 5
There is a line that includes the point (10,3) and has a slope of 1/5 What is its equation in point-slope form?
Answer:
y -3 = 1/5(x-10)
Step-by-step explanation:
The point slope form of the equation of a line is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y -3 = 1/5(x-10)
Answer:
y - 3 = m(x - 10)
Step-by-step explanation:
The point-slope form is y - k = m(x - h). Here we are told that m = 1/5, h = 10 and k = 3, and therefore we have
y - 3 = m(x - 10)
I need help on this I’ve been stuck on it for a little bit I will give you brainliest if you help me and I will give 5 stars
Answer: 27 degrees
Step-by-step explanation:
y is 63 degrees because they are alternate interior angles. Then, 90-63=27 which is the answer.
Answer:
27°
Step-by-step explanation:
One of the properties of a rhombus is it has 2 perpendicular diagonals.So each formed triangle is a right triangle.
We can see one of the angles is 63°, so z= 90° - 63°= 27°
Dan spends 1/5 of his wages on rent and 2/3 on food. If he makes £495 per week how much money does he have left

I’m confused. Thanks
Step-by-step explanation:
Angle XBC = 55 degrees because it is a corresponding angle with Angle AXC
and corresponding angles are equal or congruent.
Ok so angle XBC = 55 degrees and since this an isosceles triangle
XBC = XCB which means XCB = 55 degrees
Now to find angle BXC we know that all angles of a triangle add up to 180 degrees.
Angle XBC + Angle XCB + Angle BXC = 180 degrees
Let x represent angle BXC
55 + 55 + x = 180
110 + x = 180
x = 180 - 110
x = 70
∴ Angle BXC = 70 degrees

What is the value of X in the given right triangle? WILL GIVE BRAINLIEST!
Answer:
Please mark me brainliest and I hope this helped!
x = 45
Step-by-step explanation:
In this case, we can use the Pythagorean Theorem to figure out the other side of the triangle.
c squared - a squared = b squared
10 squared - 7 squared = b squared
100 - 49 = b squared
51 = b squared
7.14 = b
Now that we know the other side is about 7, we can assume that x is equal to the angle between 10 and 7. So x equals 45.
