Answer:
4x+4x+7x=180
15x=180
x=12
Step-by-step explanation:
Answer:
From the lines we know that that two sides are the same so the other angle is also 4x
the total of a triangle equals 180 so
4x+4x+7x=180
15x=180
x=12

Given:
Two triangles are given in the figure.
To find:
The m∠K and m∠J.
Solution:
In triangle FHK and IGJ,
[tex]m\angle F=m\angle I[/tex] [Given]
[tex]m\angle H=m\angle G[/tex] [Given]
Two corresponding angles are equal. So,
[tex]\Delta FHK\sim \Delta IGJ[/tex] [By AA similarity theorem]
All corresponding angles of similar figures are same.
[tex]m\angle K=m\angle J[/tex] ...(i)
[tex]4y^2=6y^2-40[/tex]
[tex]4y^2-6y^2=-40[/tex]
[tex]-2y^2=-40[/tex]
Divide both sides by -2.
[tex]y^2=20[/tex] ...(ii)
Taking square root on both sides.
[tex]y=\pm \sqrt{20}[/tex]
Now,
[tex]m\angle K=(4y^2)^\circ[/tex]
[tex]m\angle K=[4(20)]^\circ[/tex] [Using (ii)]
[tex]m\angle K=80^\circ[/tex]
[tex]m\angle K=m\angle J=80^\circ[/tex] [Using (i)]
Therefore, the m∠K is 80° and m∠J is 80°.

4÷16/17=
Answers
Step-by-step explanation:
Turn 4 into 4/1. Then switch 4/1 or 16/17 because I don't know which to switch. If you don't know what I'm talking about, when you switch 4/1 or 16/17, you'll get 1/4 or 17/16. Then you multiply 1/4 × 16/17 or 4/1 × 17/16. You multiply across, like this, 1 × 16 and 4× 17 Same thing with 4/1 × 17/16 but backwards (4×17 and 1×16). Do both equation (4/1 × 17/16 and 1/4 × 16/17) by yourself, then simplest it. Example: 2/4 = 1/2. You divide 2/4 by two, 2÷2 for the numerator and 4÷2 for the denominator. That how you simply.

This table shows values that represent an exponential function.
what is the average rate of change for this function for the interval from x=2 to x=4?
Answers
Answer:
Subtract the two Y values of X = 2 and X = 4 to find the total difference, then divide by the difference between X=2 and X =4
When X = 2 Y = 9
When X = 4 Y = 64
Difference between the two Y values = 64 -9 = 55
Difference between the two X values = 4-2 = 2
The rate of change = difference in Y divided by difference in X:
55/2 = 27.5

Find the difference between numbers:
Divide the second number by the first number:
36/108 = 1/33
Divide the third number by the second number:

Multiply the last known number by 1/3 for the next number:
12 x 1/3 = 4
The next term is 4

Find the range for the possible measure of the third side of a triangle given two sides?
4 cm, 6 cm
Range:
Answers
Answer:
The possible range of the measure of the third side is 2 < 3rd side < 10
Step-by-step explanation:
In any triangle:
The sum of the lengths of any two sides must be greater than the length of the 3rd sideThe length of any side must greater than the difference of the lengths of the other two sidesThe difference of the other sides < The side < The sum of the other sidesLet us solve the question
∵ The measures of the two sides of a triangle are 4 cm and 6 cm
∵ The difference between their measures = 6 - 4 = 2 cm
∵ The sum of their measures = 6 + 4 = 10 cm
→ By using the rules above
∴ The measure of the third side is between 2 and 10
∴ 2 < the third side < 10
∴ The possible range of the measure of the third side is 2 < 3rd side < 10
Howard is putting napkins on tables at a restaurant. Each table gets the same number of napkins.
• After putting napkins on 6 tables, Howard has 124 napkins remaining
• After putting napkins on 10 tables, Howard has 108 napkins remaining
How many napkins does each table get ?
Answers
Answer:
Each table gets 4 napkins
Step-by-step explanation:
Rate of change
It usually refers to how fast one quantity changes with respect to another. We are given the following information.
After putting napkins on 6 tables, Howard has 124 napkins remaining
After putting napkins on 10 tables, Howard has 108 napkins remaining
This means that Howard used 124-108=16 napkins in 10-6=4 tables.
The rate of change (or rate of use in this case) is 16 napkins/4 tables= 4 napkins per table.
Each table gets 4 napkins

I’m really hoping I do fail this assignment so can someone please help?
Answers
the answer is 99!
here is an explanation to help you understand:
the angles 81 degrees and b are supplementary angles. Supplementary angles mean that two angles have the sum of 180 degrees so you would need to find the x when you have a given already.
do an equation like this:
x + 81 = 180
here is how to answer the equation:
x + 81 - 81 = 180 - 81
x = 99
Here you only need to subtract 81 from both sides. in simple terms, do 180 minus the measure given.

1. A right angled triangle has two shorter sides and one is twice as long as the other. The hypotenuse is 25 cm long. What are the lengths of the shorter sides?
Answers
Step-by-step explanation:
The hypotenuse of a right-angled triangle = 25 cm
One side is twice as long as the other.
Let the other side is x.
First side = 2x
Using Pythagoras theorem to find the lengths of the shorter sides.
[tex]x^2+(2x)^2=25^2\\\\x^2+4x^2=625\\\\5x^2=625\\\\x^2=125\\\\x=11.18\ cm[/tex]
So, the other side = 11.18 cm
First side = 2(11.18) = 22.36 cm
So, the lengths of the shorter sides are 11.18 cm and 22.36 cm.
