The midpoint of is point P at (−16,6). If point A is at (−10,8), what are the coordinates of point B? (−42,20) (−22,4) (−13,7) (2,−5)
Answer:
B (-22 , 4)
Step-by-step explanation:
-16=(-10+x)/2
*2 *2
-10+x=-32
+10 +10
x=-22
6=(8+y)/2
*2 *2
12=8+y
-8 -8
4=y
so B(-22, 4)
The coordinates of point B is (-22, 4).
What are the Coordinates?Coordinates are the set of points in a geometrical plane or space, which is used to denote the exact point in the coordinate plane or space.
If we have the end points (x', y') and (x'', y'').
The mid point is ((x' + x'')/2, (y' + y'')/2).
Given that one of the end point A is at (-10, 8).
The mid point is at P(-16, 6).
Let the other point be B(x, y).
(-10 + x) / 2 = -16 and (8 + y) / 2 = 6
(-10 + x) / 2 = -16
⇒ -10 + x = -32
⇒ x = -32 + 10
⇒ x = -22
(8 + y) / 2 = 6
8 + y = 12
y = 12 - 8
y = 4
Hence the coordinate of the other point is B(-22, 4).

Step-by-step explanation:
A) 350cm2
B) 1000cm2
C) 170cm2
D) 1200cm2
Answer:
1200 cm^2
Step-by-step explanation:
There are four 10 cm by 25 cm sides; the total area of these sides is
4 (10 cm) (25 cm) = 1000 cm^2.
There are two ends; the total area of these is 2 (10 cm) (10 cm) = 200 cm^2.
Thus, the total surface area is 1000 cm^2 + 200 cm^2, or 1200 cm^2 (Answer A).

Find the measure of the angle O. (Remember, you are finding the actual angle measure, not the ratio.)
Round to the nearest tenth.
Answer:
Θ ≈ 22.6°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosΘ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{12}{13}[/tex] , thus
Θ = [tex]cos^{-1}[/tex] ([tex]\frac{12}{13}[/tex] ) ≈ 22.6° ( to the nearest tenth )

Step-by-step explanation:
We know that the area of a rectangle is length times width, so if we call the length y, we'll get y * (x - 3) = x² - 9.
y = (x² - 9) / (x - 3)
y = (x + 3)(x - 3) / (x-3)
y = x + 3. Hope this helps!

What additional information is needed to prove that the
triangles are similar?
To prove AXYZ - AMNO using SSS, you need to
know that
Now that you know the length of XZ, you need to know
that angle O is congruent to v to prove AXYZ- AMNO using SAS.
Can someone explain please!!!
Answer:
Step-by-step explanation:
To prove ΔXYZ ~ ΔMNO using the property of SSS, we need to know that All corresponding sides of these triangles are proportional.
Similarly, If we know the length of side XZ then addition information we need to know that angle O is congruent to angle Z and length of sides YZ, MO and NO to prove ΔXYZ ~ ΔMNO by SAS property.
Angle O is the contained angle between the sides MO and NO.
Answer:
1. MN = 6 and XZ = 17.5
2. angle Z

Lorie correctly determines that for the triangles below, the statement Triangle N M O is similar to triangle T S R and the statement Triangle N M O is similar to triangle T R S both describe the relationship between the two triangles. Triangle M N O. Angle M is 54.4 degrees and angle N is 71.2 degrees. Triangle R S T. Angle R is 54.4 degrees and angle T is 71.2 degrees. Which best describes why both similarity statements are correct? Each triangle has two congruent angles: Angle M is congruent to angle O and Angle R is congruent to angle S. Each triangle has two similar angles: Angle M is similar to angle O and Angle R is similar to angle S. The triangles each have two given angle measures and one unknown angle measure. All statements, regardless of the order of the vertices, define the same triangles.
Answer:
(A)Each triangle has two congruent angles: Angle M is congruent to angle O and Angle R is congruent to angle S.
Step-by-step explanation:
In Triangle MNO
[tex]\angle M = 54.4$ degrees, \angle N = 71.2$ degrees\\\angle M+\angle N+\angle O=180^\circ\\54.4^\circ+71.2^\circ+\angle O=180^\circ\\\angle O=180^\circ-(54.4^\circ+71.2^\circ)=54.4^\circ[/tex]
In Triangle RST
[tex]\angle R = 54.4$ degrees, \angle T = 71.2$ degrees\\\angle R+\angle T+\angle S=180^\circ\\54.4^\circ+71.2^\circ+\angle S=180^\circ\\\angle S=180^\circ-(54.4^\circ+71.2^\circ)=54.4^\circ[/tex]
Therefore:
Triangle NMO is congruent to triangle TSR; and
Triangle NMO is congruent to triangle TRS
This is because
[tex]\angle M \cong \angle O =54.4^\circ; and\\ \angle R \cong \angle S =54.4^\circ .[/tex]
The correct option is A.

A

Answer:
1. B
2. C
Step-by-step explanation:
1. In this, we already know one side and one angle are congruent. For the triangles to be congruent by SAS, another side is necessary. Thus CB = FE
2. Here, we see that one set of sides are congruent. We see another set of angles are congruent as well. We also know that the center angle is congruent as the angles are formed by two straight lines intersecting. Since we see 2 next door angles and the side beside it congruent, they are proven congruent by AAS.

2. Sarah is training for a triathlon. She is planning her training schedule and wants to know how much she should run each week. Her choices are to run 2 ¼ miles three times each week or she can run 1 ¾ miles five times each week. She wants to choose the option with the longest total distance. Which option should she choose? Explain your thinking in numbers and words.
Answer: She should run 1 1/3 miles 5 times a week.
Step-by-step explanation: I converted 3/4 to a decimal to have 1.75 and I multiplied it by 5 because that is how many times she will be running 1.75 miles in a week, I got 8.75. So that means if she runs 1.75 miles for 5 days she will run a total of 8.75 miles. Then I converted 1/4 into a decimal and now have 2.25, then I multiplied 2.25 by 3 and got 6.75. So I saw that 8.75 is greater than 6.75,
So the correct answer is: she should run 1 3/4 miles 5 times a week
55 men can finish a piece of work in 42 days. How many additional men must be added to complete the work 9 days earlier.
[tex]55 . 42 = x . 33\\55 . 14 = 11 . x\\x = 5 . 14 = 70\\70 - 55 = 15[/tex]Answer:
Step-by-step explanation:
The additional men required to complete this work 9 days earlier will be 15.
What is work time?In time and work, we need to calculate the time required to complete a unit of work and find work done in a described period of time. Its known the amount of work done by a person varies directly with the time taken by them to complete the work on time.
Given that work was done by 55 men in 42 days
55 men ⇔ 42 days
Rate of work by 1 man ⇔ 1/(55×42)
Rate of work by 1 man ⇔ 1/(2310)
Now by adding N number of people the work need to complete 9 days earlier than 33 days.
Rate of work by 1 man ⇔ 1/[(55+N)×33]
Since the rate of work by 1 man will be the same for both cases
1/(2310) = 1/[(55+N)×33]
N = 15 hence,15 men additional required to complete the work 9 days earlier.
