Answer:

Triangle 1: 13.6.7

None of the triangles are right triangles.

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.

Answer:

  540 cm³

Step-by-step explanation:

Apparently, the base of the prism is a parallelogram that is 15 cm wide and 3 cm from one side to the other. Its area is given by ...

  A= bh

  A = (15 cm)(3 cm) = 45 cm²

The volume of the prism is the product of its base area and height.

  A= Bh

  A = (45 cm²)(12 cm) = 540 cm³ . . . . volume of this prism

Answer:

Step-by-step explanation:

First page = 2 x 4.5 x 3 = 27 square feet.

Second page = 15 x 20 x 9 x 2 = 5400 cubic cmm

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.

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

Answer:

14km

Step-by-step explanation:

1 cm = 3.5km

4 cm = 3.5km * (4*1cm)

4 cm = 14 km

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

Answer: p= $8   s= $2.50

Step-by-step explanation:

3p + 4s = 34       and       3p + 7s= 41.50

Since the number of pizzas DIDNT change between these two equations, we can use the total of the second equation to help us find the price of one sandwich.

41.50 - 34 = $7.5 for 3 sandwiches  (7s-4s)

So how much is one sandwich?  7.50/3 = $2.50 for each sandwich

now that we know  s, it’ll be much easier finding p. We can use one equation to find p.

3p + 4(2.5) = 34    (Solve algebraically)

3p + 10 = 34

    - 10  |  -10

3p = 24

3p/3 = 24/3

p = $8.        Now you can check by substituting the variables!

Step-by-step explanation:

Answer:

5 is the median

Step-by-step explanation:

Median

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Answer:

D.) The mean may change, but the median will not change.

Step-by-step explanation:

By adding two new values to the existing dataset ; this two values are extreme values as described in the dataset.;

As the warmer will be the new minimum and the colder the new maximum .

The median value being the midpoint of the dataset when arranged in order will definitely not be affected by these new additions are at the beginning and end of the data set. Hence, the previous median points will Also be the new median points.

As for the mean, it has to do with calculation the average value, despite the number being at the extreme, the new points may take up any value and hence will affect the new sum and ultimately the obtained average.

Therefore,The mean may change, but the median will not change.
