The three side lengths of four triangles are given. Which triangle is a right triangle?
Triangle 1: 13.6.7
Triangle 2: 7.8.13
Triangle 3: 10, 11, 12
Triangle 4: 10.9.8
Answer:
Triangle 1: 13.6.7
None of the triangles are right triangles.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
For a triangle to be a right triangle, the Pythagorean theorem must be satisfied.
So,
Applying the Pythagorean theorem.
Triangle 1:
13, 6, and 7
13² = 6² + 7²
169 = 36 + 49
169 = 85
Not true.
Triangle 2:
7, 8, and 13.
13² = 7² + 8²
169 = 49 + 64
169 = 113
Not true.
Triangle 3:
10, 11, and 12
12² = 10² + 11²
144 = 100 + 121
144 = 221
Not true.
Triangle 4:
10, 9, and 8
10² = 9² + 8²
100 = 81 + 64
100 = 145
Not true.
Thus,
None of the triangles are right triangles.

What two numbers multiply to 30 and add to -17
Answer:
-15 and -2
Step-by-step explanation:
Since a negative times a negative equals a positive, but when added, still stays a negative, the factors must both be negative.
Negative Factors of 30:
-30 + -1 = -31
-15 + -2 = -17
-10 + -3 = -13
-6 + -5 = -11
The two factors of 30 that add up to -17 are -15 and -2.

Answer:
≈ £ 4584.38
Step-by-step explanation:
Firstly, we need to find the number of litres that Mr. Leonard needs to fill up his tank:
We know that there is already 450 litres in the 1200 litre tank, so he must need 1200 - 450 = 750 litres.
I'm not quite sure what the variable p means, but I'm going to assume that p represents the number of litres and that 81.5 is the price per litre in pounds.
So:
Total price = 81.5p
Total price = 81.5(750)
Total price = £61125
We have to remember though that the question is asking for the discount and not the discounted price, so:
61125 × 7.5%
61125 × 0.075 = 4584.375
≈ £ 4584.38

How can you solve this equation? 15 = y - 5
A. Subtract 5 from each side.
B. Subtract 15 from each side.
C. Add 5 to each side.
D. Add 15 to each side.
Answer:
C) add 5 to each sides.
Step-by-step explanation:
1) Add 5 to both sides.
[tex]15 + 5 = y[/tex]
2) Simplify 15 + 5 to 20.
[tex]20 = y[/tex]
3) Switch sides.
[tex]y = 20[/tex]
You need to add 5 to each sides in order to solve this equation. if you do, you'll get an answer of 20.

The width of a rectangle measures (9h 1) centimeters, and its length measures
(2h – 4) centimeters. Which expression represents the perimeter, in centimeters, of
the rectangle?
0-2 + 8h
0-10 + 22h
Submit Answer
16h - 4
0-5 + 11h
Answer:
(22h - 8) centimeters
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
= 2{(9h - 1) + (2h - 4)}
= 2(9h - 1 + 2h - 4)
= 2(11h - 4)
= (22h - 8) centimeters

Decrease £120 by 12.5%
Answer:
£ 105.
Step-by-step explanation:
Since it is required to decrease £ 120 by 12.5%, to perform this subtraction the following mathematical operation must be performed:
100 - 12.5 = 87.5
100 = 120
87.5 = X
87.5 x 120/100 = X
10,500 / 100 = X
105 = X
Thus, decreasing £ 120 by 12.5% you get a total of £ 105.

Probabilities. Please help
In throwing a dice, there are 6 possible outcomes, namely 1, 2, 3, 4, 5 and 6.
P=(no. of favourable outcomes)/(no. of possible outcomes)
When we multiply the probability of an event with no. of trials, the we get the expected frequency of that event.
1) P(getting 1)=1/6
expected frequency of getting 1
=P(getting)1)×no. of trials
=1/6×600=100
But it is given that one is scored 200 times, so it makes a large difference from expected frequency, which is 100.
Therefore, the dice is not fair.
2) P(getting a tail)=0.3
estimate for the number of times the coin will land on a tail
=expected frequency of getting a tail
=P(getting a tail)×no. of trials
=0.3×150=45
3)P(getting a six)=2/3
expected frequency of getting a six
=P(getting a six)×no. of trials
=2/3×300=200
4)P(getting a three)=0.5
expected frequency of getting a three
=P(getting a three)×350
=0.5×350=175

The tip of a 8 cm minute hand of a clock sweeps out circular arcs.
What is the length of the arc made by the tip of the minute hand between 3:12 and 3:32?
Use 3.14 for pi. Round your answer to the nearest hundredth.
Enter your answer in the box.
Answer:
16.75 cm
Step-by-step explanation:
The circumference of the circle is πd
The diameter is 16, so the circumference is 16π.
The minute hand goes for 20 min between 3:12 and 3:32
20 min is 1/3 of 60 min.
Therefore, the minute hand swept 1/3 of the circumference, or 1/3(16)π
1/3(16)π = 1/3(16)(3.14) = 16.75 cm
