Find the perimeter of the triangle.
Answer:
39
Step-by-step explanation:
Alll the sides equal each other because of that curve u see at each angle, that curve means that the angles are the same, having the same angles means same sides, so just pick two equations to do this:
21 - x = 2x -3
add 3 to both sides
24 - x = 2x
add x to both sides
24 = 3x
divide by 3
8 = x
Now input 7 into the equations:
21 - x = 21 - 8 = 13
2(8) - 3 = 16 - 3 = 13
x + 5 = 8 + 5 = 13
Now add: 13 + 13 + 13 = 26 + 13 = 39
Another way for u to save time is remember how i said all the sides were the same? you could just solve one equation, so it'll be 13 and multiply that with 3 to get the perimeter since ur adding 13 three times anyway
So just a simple: 13(3) = 39
Whats the reciprocal for -4
Answer:
It is n-1. Does this help any or not?
Answer:
1/4
Step-by-step explanation:
so -4 is basically -4/1, you flip that and change the negative symbol to positive, making it 1/4.
what is the measure of
Since you know a line is = 180*
if angle EFG is 125, we can get angle EFD = to 180-125=55
And since we know that the line ED is congruent to line EF, angle EDF is = 55
180-55*2= 70
angle DEF=70

Factor the binomial: x^2 - 8x
Answer:
x2+8x+15=(x+5)(x+3)
Step-by-step explanation:
Trinomials have the form: ax2+bx+c. When factoring trinomials where a=1
Answer:
x(x - 8)
Step-by-step explanation:
First, factor out an x from both terms:
x² - 8x
x(x - 8)
So, the factored form of the binomial is x(x - 8)
An airplane pilot over the Pacific sights an atoll at an angle of depression of 5 . At this time, the horizontal distance from the airplane to the atoll is 4629 meters. What is the height of the plane to the nearest meter?
Answer:
404.98 m
Step-by-step explanation:
The angle of depression is 5°
The horizontal distance from the airplane to the atoll is 4629 meters.
We need to find the height of the plane.
If we consider a triangle. 4629 meters will be the base and angle is 5°. Let h is the height of the plane. Using trigonometry to find it :
[tex]\tan\theta=\dfrac{x}{4629 }\\\\\tan(5)=\dfrac{x}{4629 }\\\\x=\tan(5)\times 4629 \\\\x=404.98\ m[/tex]
So, the height of the plane is 404.98 m.
In an Animal shelter, the ratio of dogs to cats is 5 to 3. There are 25 dogs, how many cats are there?
Answer: 25:15
Step-by-step explanation: in the ratio 5:3 the 5 is dogs and the 3 is cats you multiply the 5 (aka the dogs) by 5 to get 25 (the amount of dogs in the shelter) when you multiply 3 by 5 you get the amount of cats which is 15, a good way to remember is what you do to one side you have to do to the other. I hope this helps.

Manny's cleaning supply store receives a mixture of 80% detergent and 20% water in 15-gallon buckets. Manny would like a mixture of 60 detergent and 40% water in a 5 gallon buckets. To make this he combined some 80/20 mixture with some pure water in each 5 gallon bucket. How much gallons of pure water does Manny add to each 5 gallon bucket.
Answer:
1.67 gallons
Step-by-step explanation:
Given that:
Original mixture contains 80% detergent and 20% water in a 15 gallon bucket.
New Mixture to contain 60% detergent and 40% water of 5 gallon bucket.
To find:
Volume of Pure water to be added to each 5 gallon bucket to obtain the new mixture.
Solution:
First of all, let us calculate the answer by adding pure water to 15 gallon bucket.
Let the number of gallon of water to be added = [tex]x[/tex]
New volume = (15+[tex]x[/tex]) gallons
Now, let us compare the number of gallons of water in the mixture before and after.
[tex]15\times 20\% + x = (15+x)\times 40\%\\\Rightarrow (3+x)\times 5 = (15+x)\times 2\\\Rightarrow 15+5x=30+2x\\\Rightarrow 3x=15\\\Rightarrow x =5\ gallons[/tex]
Therefore, to a 15 gallon bucket (80% detergent and 20% water)of detergent mixture, if we add 5 gallons of pure water , it will become 60% detergent and 40% water.
To a 5 gallon bucket, the number of gallons of water to be added = [tex]\frac{5}{3} =\bold{1.67\ gallons}[/tex]

What is the area of square UVWX?
Area= ... square units
Answer:
16
Step-by-step explanation:
4*4=16
Answer:
let's take the side XW
x =( -4, -4)
w = (-4,-8)
x1= -4 & x2 = -4
y1 = -4 & y2 = -8
using formula
[tex]d = \sqrt{ (x2 -x1) ^{2} + (y1 - y2) ^{2} } \\ = \sqrt[ ]{ (- 4 - ( - 4)) + ( - 4 - ( - 8))} \\ = \sqrt{0 + 4 } \\ = \sqrt{4} = 2sq.unit \: \\ now \: area \: of \: square \: = {side}^{2} \\ so \: = \: {2}^{2} = 4square \: unit \: [/tex]
here we end :P

mike is buying a large pizza the pizza cost $8.00 plus .50 for each addition topping write an equation to show the cost of a large pizza
Answer:
8+(X×0.50)=y
Step-by-step explanation:
We know it costs 0.50 for extra toppings, so X=the amount of toppings and we multiple that by the cost of the toppings. So lets pretend you're getting 3 toppings. 8+(3x0.50)=9.50
