A triangle has sides with lengths of 21m, 28m, and 49m. Is it a right triangle?
Answer:
To find : If 21m, 28m and 49m form a right angle or not.
Logic : To find if this triangle is a right angle, we can use the Pythagoras Theorem, which states that the square if the longest side should be equal to the square of the sum of the other two sides.
The name of the longest side is called the hypotenuse, while the others are called legs or one is the perpendicular and the other the base.
Proof : [tex]h^{2} = p^{2} + b^{2}[/tex]
=> [tex]49^{2} = 28^{2} + 21^{2}[/tex]
=> 2401 = 784 + 441
=> 2401 ≠ 1225
Therefore these side lengths cannot be the lengths of a right angled triangle.

1) =========================
14 + (-12) = 14 - 12 = 2Option C)2) =========================
7 - (-7) = 7 + 7 = 14Option D)3) =========================
8 + (-12) = 8 - 12 = - 4- 4 + 4 = 0Option A)5) =========================
22 - 27 + 10 = 5Option B)Answer:
1.) C
2.) C
3.) A
5.) B
Step by-step explanation:
1.) because 14 is positive and the opposite of 12 is -12. So 14+-12=2!
2.) to get to 7 from -7 you would have to take 7 units to get there.
3.)Given that a football player caught the ball and made a gain of 8 yards on the first play. On the next play the team lost 12 yards.we are to find the number of yards needed to gain on the next play to get back to their original position.Let, x be the number of yards that the team had originally.On the next play, the team lost 12 yards, let 'k' be the number of yards needed to gain on the next play to get back to their original position.Thus, the number of yards needed to gain on the next play to get back to their original position is 4.
5.) We have been given that on Monday morning the temperature was 38°F, but by the afternoon the temperature had risen 22°F. We are also told that on Tuesday morning the temperature had dropped 27°F since Monday afternoon.Since the temperature rose by the Tuesday noon, so temperature by Tuesday noon will be 10 degrees greater than temperature by Tuesday morning.To find the number of degrees temperature is above or below 38°F on Tuesday at noon we will subtract 38°F from the temperature on Tuesday at noon. Since the difference between temperature is positive, therefore, the temperature on Tuesday at noon was 5 above .

Write an equation for a line that is parallel to y = -4x + 2 and passes through the point (-2, 5).
Answer:
y = -4x - 3
Step-by-step explanation:
y = -4x + 2
Substitue Y and X and turn 2 into b(or y intercept)
5 = -4(-2) + b
Solve for b
5 = 8 + b: subtract 8 from both sides
-3 = b
substitute for 2 with same slope(to keep parrallel)
y = -4x - 3

Answer: option C.) an 1.2 (n-1) -5 Sorry, no subscript for "a sub n"
Step-by-step explanation:
Substitute the values of n 1,2,3,4 and see if the output is the corresponding number in the sequence.
n = 1 2 3 4
-5 -3.8 -2.6 -1.4
an= 1.2 (n-1) -5 the n-1 needs to be a number multiplied by 1.2 produces a number added to -5 results in the number in the sequence.
a1=1.2(1-1) -5 a= 1.2(0) -5 a= -5
a2 1.2 (2-1) -5 a= 1.2(1) -5 a= -1.2 -5 a= -3.8
a3 1.2 (3-1) -5 a= 1.2(2) -5 a= -2.4 -5 a= -2.6
a4 1.2 (4-1) -5 a= 1.2(3) -5 a= -3.6 -5 a= -1.4

Answer:
The difference in cost per mile is $0.94.
Step-by-step explanation:
Uber
7x = 20.37
x = $2.91 per mile
Lyft
4y = 15.4
y = $3.85 per mile
3.85 - 2.91 = 0.94
Hello.
To find the difference in cost per mile, divide the cost by the amount of miles, then subtract the two answers.
20.37 / 7 = 2.91 (cost per mile {cpm} for Uber)
15.40 / 4 = 3.85 (cost per mile {cpm} for Lyft)
3.85 - 2.91 = 0.94
The difference in cost per mile is $0.94
the relationship between NP and PQ if point P is midpoint of NQ
Answer:
NP=PQ
Step-by-step explanation:
p is MIDpoint of NQ so basically distance of N to P is equal to distance of P to Q
The relationship between NP and PQ if point P is the midpoint of NQ is:
- NP + PQ = NQ
- 1/2 x NQ = NP = PQ
Given,
P is the midpoint of NQ.
We need to find the relationship between NP and PQ if point P is the midpoint of NQ
What does it mean to have a midpoint?The midpoint between two points in a line always divides the line into two equal parts.
The sum of the divided parts is always equal to the original line.
Half of the original line is equal to each part.
Example:
A_____B_____C
B is the midpoint.
We have,
AC = AB + BC
1/2 x AC = AB = BC
We have,
P is the midpoint of NQ
Now,
N______P______Q
Since P is the midpoint we can say that,
NP + PQ = NQ
And,
1/2 x NQ = NP = PQ
Thus the relationship between NP and PQ if point P is the midpoint of NQ is:
- NP + PQ = NQ
- 1/2 x NQ = NP = PQ
