A right triangle has legs of 30m and 40m. What is the PERIMETER of the triangle?
choices:
A.) 120m
B.) 70m
C.) 1200m
D.) 50m
Answer:
A
Step-by-step explanation:
We know that we are dealing with a right triangle. Look at the legs given to us, 30m and 40m. That looks familiar doesn't it? In fact, this quite resembles the 3-4-5 special right triangle.
We can simply scale the legs by 10 to find the last side of the triangle.
[tex]3*10=30\\4*10=40[/tex]
and therefore, the last side of the right triangle must be:
[tex]5*10=50[/tex]
Great! Now we have all the sides of the right triangle. We just have to add them up:
[tex]30+40+50=120[/tex]
Therefore, the perimeter of the triangle is 120m. A.
I hope this helps! Let me know if you have any questions :)

which angles are complementary to each other? select all that apply.
Answer:
it's either B or D since they are vertical
Step-by-step explanation:
complementary angles add up to 90 degrees so it would be 1 but that isn't an option

The coach of the field hockey team can spend at most $475 on new team uniforms. The coach will order the uniforms online and pay a mailing cost of $11. If each uniform costs $29, how many uniforms can the coach order?
Answer:
16
Step-by-step explanation:
475-11-29n=0, so 464= 29 n. so n would be 16
Answer:
16 uniforms
Step-by-step explanation:
his budget:475
mailing cost:11
remaining budget:475-11=464
now,
cost of one uniform= 29
no of uniform he can order is= 464÷29= 16

b= 36 degrees
c= 108 degrees
Answer:
a 18
b 108
c 36
Step-by-step explanation:
each quad is 90°
purple is 18 because 90/5
green is 36 because (90-18)/2
orange is 108 because 180-36x2
The equation of the line is
a. y=2x+3
b. y=-2x+3
c. y=3x-2
d. y=-2x+1.5
Side note: please show your work
Answer:
b. y=-2x+3
Step-by-step explanation:
find slope by getting any 2 points form the graph
(0,3) (1,1)
m = (y2-y1) / (x2-x1)
m = (1-3) / (1-0) = -2 it means by moving one unit right you need to move 2 unit down
note that it does not matter which points you chose to be second or first
then use slope point equation again it does not matter which point from the slope you use
y - y1 = m ( x - x1 )
y - 3 = -2 ( x - 0)
y = -2x +3
a) 2x+3
Step-by-step explanation:
The line passes throught the point (1;1) and (0;3)
gradient(m) =change in y ÷ change in x
=y1-y2 ÷x1-x2
=1-3 ÷ 1-0
=-2
therefore m is -2.
y-y1=m(x-x1)
y-1=-2(x-1)
y=2x+2+1
y=2x+3

I need help with find the area of the other shapes. Like you can give me an example of the width and lenth like this (8:7) and I'll put a pic of what I've got so far and I need you to do what I did please.I really need help.
You must include the following items: • At least 10 shapes in which you can calculate the area (label the dimensions for each shape in feet 1 cm=3.25feet) o 2 rectangles o 1 rhombus o 3 triangles (1 must include a fractional base) o 2 trapezoids (1 base must be a decimal) o 1 pentagon o 1 irregular polygon in which you’ll have to decompose into smaller shapes. And if my pic ain't clear enough sorry.

On your cell phone bill, you are charged $0.25 for each text you send. What is the dependent variable?
Answer:
the amount of money that you are charged
Step-by-step explanation:
the dependent variable is defined as a variable which changes depending on the other variables that are manipulated in a function so what that means is that the inputs are independent variables and the outputs are the dependent variables and in the case of this question the amount of texts sent are the independent variables and the amount charged is the dependent variable

The front and back sides are both triangles, explain why you arent going to divide the base x height by 2.
Answer:
4x=Bf
Step-by-step explanation:
Pls help me so I can pass
Answer:
The slope of the line is constant. This is because all straight lines have a constant slope. The slope of this line is 1/3. When you use the legs to measure, the horizontal legs of the triangle, they increase in length by 3 units from the previous triangle. The vertical legs of the triangle also increase by 1 with each added triangle. Both of these observations support that the slope of the line is a constant 1/3.

Answer:
C
Step-by-step explanation:
1. π ≈ 3.1415. π + 10 ≈ 13.1415.
2. Find the square root of 20. It is about 4.4721. 4.4721 + 1/2 (or .5) = 4.9721
3. The square root of 100 is 10.
4. Order them.
5. It is most obvious that the answer to [tex]\sqrt{20\\}[/tex] + 1/2 is first. The square root of 100 is ten, so that goes second because pi + 10 is greater than 10. (pi + 10 goes last)
6. [tex]\sqrt{12} + 1/2, \sqrt{100}, \pi + 10[/tex]

Answer:
382 is the answer for the addition.
Step-by-step explanation:
you don't really need the side panel, however it seems it was included in the problem itself. however simply adding the first numbers together will give you the correct answer, and adding the 3 seperate numbers on the bottom will give you the same: 382.
PLEASE HELP ASAP!
Consider the 720 permutations of the numbers 1, 2, 3, 4, 5, 6. In how many of these permutations do exactly 3 of the numbers end up in the positions where they started?
The set {1,2,3,4,5,6} has a total of 6! permutations
a. Of those 6! permutations, 5!=120 begin with 1. So first 120 numbers would contain 1 as the unit digit.
b. The next 120, including the 124th, would begin with 2.
c. Then of the 5! numbers beginning with 2, there are 4!=24 including the 124th number, which have the second digit =1
d. Of these 4! permutations beginning with 21, there are 3!=6 including the 124th permutation which have third digit 3
e. Among these 3! permutations beginning with 213, there are 2 numbers with the fourth digit =4 (121th & 122th), 2 with fourth digit 5 (numbers 123 & 124) and 2 with fourth digit 6 (numbers 125 and 126).
Lastly, of the 2! permutations beginning with 2135, there is one with 5th digit 4 (number 123) and one with 5 digit 6 (number 124).
∴ The 124th number is 213564
Similarly reversing the above procedure we can determine the position of 321546 to be 267th on the list.
What is the solution to the equation?
2/3a - 1/6 = 1/3
Answer:
a = 3/4
Step-by-step explanation:
2/3a - 1/6 = 1/3
Multiply each side by 6 to clear the fractions
6*(2/3a - 1/6) = 6*1/3
Distribute
4a - 1 = 2
Add 1 to each side
4a -1+1 = 2+1
4a = 3
Divide each side by 4
4a/4 = 3/4
a = 3/4
Answer:
a= 1/3
