Step-by-step explanation:
TU is parallel to IJ. So ∠I and ∠T are corresponding angles, and ∠U and ∠J are corresponding angles.
By AA similarity, ΔHTU and ΔHIJ are similar.
Write a proportion:
HT / HI = HU / HJ
Plug in values:
4 / 10 = x / (x + 9)
Cross multiply:
4 (x + 9) = 10x
4x + 36 = 10x
36 = 6x
x = 6
So HU = 6, and HJ = 6 + 9 = 15.
There are 25 female performers in a dance recital. There ratio of men to women is 2:5. How many men are in dance recital.
Answer:
There are 10 men in the dance recital.
Step-by-step explanation:
The ratio 2:5 means that for every 5 women there are 2 men.
We will divide 25 by 5 to figure out how many groups there will be.
[tex]25/5=5[/tex]
[tex]x*y=z[/tex]
x = amount of groups.
y = amount of men per group
z = total amount of men.
[tex]5*2=10[/tex]
This means that there are 10 men in the dance recital.

Rectangle QUAD has coordinates Q(0,0), U(0,3), A(7,3), and D(7,0). Q'U'A'D' is the image of QUAD after a dilation with center (0,0) and scale factor 6. What are the coordinates of point U '?
Answer:
22
Step-by-step explanation:
After dilation with center (0,0) and scale factor 6 new coordinates of point U are ( 0, 18).
What is dilation?" Dilation is defined as to resize the given geometrical shape with given scale factor."
Formula used
Scale factor
= (Dimensions of new shape) ÷ (Dimensions of original shape)
According to the question,
Given rectangle QUAD,
Coordinates of Q(0,0)
Coordinates of U(0,3)
Coordinates of A(7,3)
Coordinates of D(7,0)
Q'U'A'D' is the image of QUAD after a dilation with center (0,0) and scale factor 6.
New Coordinates of Q'(0,0)
New Coordinates of U'(0,18)
New Coordinates of A'(42,18)
New Coordinates of D'(42,0)
Hence, after dilation with center (0,0) and scale factor 6 new coordinates of point U are ( 0, 18).

volume =160.875m, length =6.5m, height =5.5m, breadth =?
Answer:
b = 4.5 m
Step-by-step explanation:
Since we have 2 sides of the shape and the total volume, we can easily find the measurement of the third side which is the breadth by:
volume = 160.875
v = l×h×b
160.875m=(6.5m)×(5.5m)×b
160.875m=35.75b
b = 4.5 m
Answer:
4.5m
Step-by-step explanation:
v=lbh
b=v/lh
= 160.875/(6.5×5.5)
=160.875/35.75
=4.5m

Marissa has a goal of shooting exactly 400 three–pointers during her basketball practice every week. She has already shot 105 of them over the first two days of practice. Write an equation to represent how many three–pointers (t) Marissa has to average over the next 5 days to reach her goal.
Answer: 5t = 400-105
Step-by-step explanation:
Let t= Number of three–pointers Marissa has to average over the next 5 days to reach her goal. .
Goal = 400 three–pointers every week.
Marissa has already shot = 105 three–pointers
Remaining shots to achieve target (5t) = Goal - (Marissa has already shot)
i.e. 5t = 400-105 (required equation)
⇒ 5t = 295
⇒ t = 59
hence, she need to make 59 shots per day for next 5 days.

The slope of the given data in the table will be 25.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
The formula to calculate the slope of the line will be given below:-
m = (y₂ - y₁) / (x₂ - x₁)
Given data is as below:-
Number of months Savings Principal
5 $125
6 $150
7 $175
8 $200
The slope will be calculated as below:-
m = (y₂ - y₁) / (x₂ - x₁)
m = ( 150 - 125 ) / 6 - 5 )
m = 25
Therefore, the slope of the given data in the table will be 25.

The sum of three odd numbers is odd and that added to an even number results in an odd number.
What are some other related concepts?An even number raised to the even or odd power is even and an odd number raised to the power of even or odd is always an odd number.
We know the sum of two even numbers is even, the sum of two odd numbers is also even and the sum of an odd and even number is odd and vice versa.
Given four numbers first two numbers are odd so their sum is even.
The next two numbers are even and odd so their sum is odd, Now the sum of even and odd is odd.
