Use the Pythagorean theorem to find the length of the hypotenuse. HELP ILL MARK THE BRAINLIEST!!
Answer:
10cm
Step-by-step explanation:
The Pythagoras Theorem states that
[tex]a^2+b^2=c^2[/tex]
Where a and b are two sides in a right-angled triangle and c is the longest side. (Hypotenuse).
Plug in values:
[tex]6^2+8^2=c^2[/tex]
[tex]36+64=c^2[/tex]
[tex]c=\sqrt{100}[/tex]
[tex]c=10[/tex]
I don't understand Division. Can you help?
Answer:
It's a bit hard to explain, in my opinion. but I'll give it a go. Lets say you have 10 full pizzas, and you want to split it upon 5 people. Now 5 2 slices is 10, like 5x2 so basically, it's kind of like backwards multiplying. if that makes sense. Think of it like this. if you see something like 14 ÷ 2, think of what number times 2 would be 14. 7, exactly. So Just write the number thats missing. Thats how i like to think of it. What number is missing.
Step-by-step explanation:
Sorry if this doesnt make sense and sorry if you dont understand.
I just started 6th grade so im not sure if i had the right idea in my noggin

Leon throws a ball off a cliff. The graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds. What is the domain? {t| 0 ≤ t ≤ 3} {t| 0 ≤ t ≤ 48} {t| 0 ≤ t ≤ 64} {t| all real numbers
Answer: t 0<t<3
Step-by-step explanation:
Answer:
The correct option is 1.
Step-by-step explanation:
The given graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds.
The value of height and time can not be negative, there the values of h and t must be greater than 0.
The set of all possible inputs is called domain. In the graph x axis represent the domain and y-axis represent the range.
The graph is defined from t=0 to t=3.
Therefore option 1 is correct.

Show your work.
Answer:
-11x-5x^2+5x^3
Step-by-step explanation;
8x^3-x-10x+5x^2+3x^3 (distribute the negative sign)
8x^3-3x^3 -x-10x (combine like terms)
5x^3-11x-5x^2

What is LaTeX: m\angle PTQm ∠ P T Q?
line ps intersecting with line qr at point t. angle ptq is x + 28 degrees. angle rts is 2x + 16 degrees.
Group of answer choices
140
40
50
12
Answer:
B. 40Step-by-step explanation:
If line ps intersecting with line qr at point t as shown, then ∠ P T Q = ∠RTS (oppositely directed angle)
Given
PTQ is x + 28
RTS is 2x + 16
Since they are both equal, then x+28 = 2x+16
collect like terms
x-2x = 16-28
-x = -12
multiply both sides by -1
-1(-x) = -1(-12)
x = 12
Since ∠ P T Q = x+28, substitute x = 12 into the function
∠ P T Q = 12+28
∠ P T Q = 40
Hence measure of ∠ P T Q is 40°

The set of ordered pairs (t, m) where m is
the remaining mass of a 500-gram sample
of a radioactive substance that has been
decaying for t hours.
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis

If a = -2, b= -5, and c = -6, then a - b + c=?
Answer:
a - b + c = - 3
Explain
a = - 2
b = - 5
c = - 6
Now,
a - b + c = - 2 - (-5) + (-6)
= - 2 + 5 - 6
= - 8 + 5
= - 3
Solve for v 3(v-2)=7v+6-2(-4v-3)
Answer:
v= -1.5
Step-by-step explanation:
3(v-2)= 7v+6-2(-4v-3)
3v-6= 7v+6+8v+6
3v= 15v+18
-12v= 18
v= -1.5

- If JL = 5x + 2, find JL.
Answer:
JL= 62
Step-by-step explanation:
27+3x-1=5x+2
3x+26=5x+2
3x+24=5x
24=2x
12=x
now plug in x(which is 12) for JL
5(12)+2
60+2
=62
The measure of the line segment is 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
JL = 5x + 2
From the line segment:
JL = 27 + 3x - 1
Plug the value of JL in the equation:
5x + 2 = 27 + 3x - 1
After solving:
5x - 3x = 26 - 2
2x = 24
x = 12
JL = 5x + 2
Plug x = 12 in the above equation:
JL = 5(12) + 2
JL = 60 + 2
JL = 62 units
Thus, the measure of the line segment is 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.
