Aright triangle has leg lengths of 7 centimeters and 24 centimeters.
What is the length of the triangle's hypotenuse?
Answers
A^2 + b^2 =c^2
=
49+576=c^2
625=c^2
c= sqrt 625
c=25
Answer:
25 centimeters
Step-by-step explanation:
We can use the Pythagorean Theorem to find the length of a missing side of a right triangle
Pythagorean Theorem: a² + b² = c²
where a and b = legs and c = hypotenuse
For the following problem we are given two legs and need to find the hypotenuse, to do so we simply plug in the length of the legs and solve for the hypotenuse or "c"
Leg lengths = 7 and 24
So a = 7 and b = 24
So we plug in 7 and 24 for a and b and solve for c
a² + b² = c²
a = 7
b = 24
(7)² + (24)² = c²
simplify exponents
49 + 576 = c²
add 59 and 576
625 = c²
take the square root of both sides
√625 = 25
√c² = c
we're left with c = 25
So the length of the hypotenuse would be 25 centimeters

Find a, R, and T.
Answers
a = 4, R = 147, T = 33
Step-by-step explanation:
find a
a/(a + 7) = (16/3)/(44/3)
a/(a + 7) = 16/44
44a = 16a + 112
44a - 16a = 112
28a = 112
a = 112/28
a = 4
find R
2x + 5 = 3x - 9
5 + 9 = 3x - 2x
14 = x
m ∠R = 180° - (2x + 5)
= 180 - (2(14) + 5)
= 180 - (28 + 5)
= 180 - 33
= 147°
find T
m ∠T = 3x - 9
= 3(14) - 9
= 42 - 9
= 33°

Which table represents a linear function?
Answers
Answer:Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.
So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values.
For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.

the hypotenuse side is always the longest so its 28
:

Complete the statement.
Answers
Answer:
angle 4 = 56°
Step-by-step explanation:
Interior angles in the same side of the transversal are supplementary (their sum is 180°)
Angle 1 and 4 are interior angles on the same side of the transversal.
So, angle 1 + angle 4 = 180°
Angle 1 = 124° (given)
124 + angle 4 = 180°
angle 4 = 180° - 124° = 56°
Therefore, angle 4 = 56°

Answers
Answer:
-9+30x
Step-by-step explanation:
-3 x 3 is -9
-3 x -10x is 30x
Answer:
-9 + 30x
Step-by-step explanation:
Like you mentioned, to solve this expression we need to use the distributive property...
We have to distribute -3 to 3 and -10x.
When multiplying negative and positive numbers it is important to know that...
-negative times negative equal positive
-negative times positive equal negative
-3 · 3 = -9
-3 · -10x = 30x
Therefore the answer is -9 + 30x

you are driving to a friends house at 35 miles per hour and the friend lives 21 miles away. how long to get to the house
Answers
Answer:
35miles/1 hr=21miles/x hr
= x hr* 35miles/1 hr= 21 miles
= x = 21/35 =0.6 hr
So, traveling at 35mph it will take 0.6 hours to travel 21 miles.
If you want time in mins then keep going:
=> 60 mins = 1 hour, 0.6 hours = x mins
60mins/1 hr = x mins/ 0.6 hr
0.6 * 60 mins = 36 mins.
:. It takes 0.6 hrs or 36 mins to drive 21 miles at a constant speed of 35mph
