Points E, D, and H are the midpoints of the sides of ΔTUV. UV=110, TV=140, and HD=110. Find HE.
Answers
The required value of HE is 55 units.
What is proportion?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal.
Now it is given that Points E, D, and H are the midpoints of the sides of ΔTUV.
UV = 110,
TV = 140, and
HD = 110
Since the triangles are similar there exists correspondance in the angles, so in order to solve this you just have to clear the function:
HD/HE = TV/(TV/2)
Put the values we get,
110/HE = 140 / 70
⇒ HE = 110*70/140
⇒ HE = 55 units
Thus, the required value of HE is 55 units.

The values x and y are found as (x = -7) and (y = 5).
What is defined as the system of equations?When there is more than one unidentified and enough content to set up equations within these unknowns, systems of equations are being used to solve applications. In general, we require sufficient information to established n equations in n unknowns if there are n unknowns.One solution exists for a set of 2 or more equations usually contains a set of common variables. When there is no solution to a system of equations with different slopes.The two given equation are-
-2x - 6y = -16 .......equation 1
4x - 6y = -58 .......equation 2
Multiply equation 1 with -1.
-(-2x - 6y = -16)
Solve by eliminations; subtract equation 2 from 1.
2x + 6y = 16
4x - 6y = -58
Further simplifying;
6x = -42
divide both sides by six
x =- 7
Put the value of x equation 1.
2(-7) + 6y = 16
-14 + 6y = 16
6y = 30

A costs $25 plus an additional $0.09 for each minute of calls. Plan B has no initial fee but cost $0.11 for each minute of calls
Answers
For 1,250 minutes, both plans will charge the same amount.
For how many minutes both plans charge the same?We know that Plan A costs $25 plus $0.09 per minute, so if you have x minutes of calls, the cost is given by the linear equation:
A(x) = $25 + $0.09*x
And plan B just charges $0.11 for each minute, then here we have the linear equation:
B(x) = $0.11*x
The costs are the same when:
A(x) = B(x)
$25 + $0.09*x = $0.11*x
Now we can solve this for x.
$25 = $0.11*x - $0.09*x = $0.02*x
$25/$0.02 = x = 1,250
We conclude that for 1,250 minutes, both plans will charge the same amount.

Amy has three times as many Star Wars toys as Carly. Total they have 232 Star Wars toys. How many Star Wars toys does Amy have?
Answers
Answer:
174
Step-by-step explanation:
Since we don't know how many toys Carly has, we'll use a variable (x). The equation would then be:
x+3x=232
We can then combine like terms, and the new equation would be:
4x=232
Now, we have to get x by itself. To do this, divide both sides by 4, and you get:
x=58
But, remember, x is how many Carly has. Amy has three times that, so:
58*3=174
Amy has 174 toys.

How to Partition a Line Segment?Partitioning of a line segment means dividing the line segment in the given ratio. The two numbers in the ratio must add up together to equal the total number of partitions of the line segment. For example: If a line segment AB is divided into a ratio of 2:3, it shows that the line segment can be divided into 5 equal sections. Hence, there are 5 parts in total, in which 2 parts will be before the desired point and 3 parts will be after the desired point.
We are given a line segment A F divided into different parts of points B, C, D and E.
Now, we want to find the point K such that it divides Line segment A F in the ratio 4:5.
Now, from the number line, line A F measures 12 units. Thus;
Point K = (4/5) * 12 = 5¹/₃ from point A

If the function of height in time is h(t)=-4.9[tex]t^{2}[/tex]+106t+206,then the rocket will splash down into the ocean after 23.43 seconds and the rocket will get its peak after 10.82 seconds at a height of 779.26524 meters above the sea level.
Given that the function of height in time is h(t)=-4.9[tex]t^{2}[/tex]+106t+206.
We are required to find the time after which the rocket will splash down into the ocean and the time after which the ocean will get its peak and the height of the rocket.
The rocket will splash down when the height of the rocket is 0.
-4.9[tex]t^{2}[/tex]+106t+206=0
