1. Find six rational numbers between 2/7 and 5/2​

Answer:

Step-by-step explanation:

Sum of angles of a triangle = 180

x + (180 - 105) + (180 -140) = 180

x + 75 + 40 = 180

x = 180 -75 - 40

x = 65

Answer:

This is false. Lines will be congruent if they have the same length, which is not the case in all situations.

Answer:

Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.

Answer:

∠A = 126°

Step-by-step explanation:

Supplementary angles are angles that add up to equal 180°

Given that ∠B = 54°, we can subtract 54° from 180°.

180° - 54° = 126°

∠A = 126°

Answer:

Following are the solution to the question:

Step-by-step explanation:

[tex]p = 0.43\\\\n = 243\\\\\sigma =\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.43 (1 -0.43)}{243}}=0.0013[/tex]

z-score for [tex]\hat{p}=0.2[/tex] will be:

z score for will be:

[tex]z=\frac{\hat{p}-p}{\sigma}=\frac{0.39 - 0.43}{0.0013}=-30.76[/tex]

[tex]P(0.2 <\hat{p}< 0.39) = P(-176.92 < z < -30.76)[/tex] using excel method to calculate the value.

Answer:

The HCF is 75

Step-by-step explanation:

Here, we want to get the highest common factors of the two numbers

To do this, we have to write the numbers as the product of their prime factors

We have;

3,000 = 2 * 2 * 2 * 3 * 5 * 5 * 5

525 = 3 * 5 * 5 * 7

now looking at this, we can see that in both numbers, we can have 3 * 5 * 5 taken out as it is common to both numbers

This represents the highest common factor of the two numbers

and that is 75

Step-by-step explanation:

Answer: 60

Step-by-step explanation:

Answer:

r = 0.05 or 5%

Step-by-step explanation:

3450 = 3000 + (3000 · r · 3)

450 = 9000 · r

450/9000 = r

r = 0.05 or 5%

Step-by-step explanation:

Answer:

mean = 2

median = 2.5

Step-by-step explanation:

There are a total of 20 goals  (1*0 + 3*1 + 1*2 + 3*5 = 0 + 3 + 2 + 15 = 20)

There are 10 games, so 20/10 = 2 = mean

Threre are 5 games with goals greater than 2.5 and 5 games with goals below 2.5.  So the median is 2.5

Answer:

4ft

Step-by-step explanation:

to get the area of a square you multiply the sides together so you just find the square root of the area

Answer:

4 feet would be the legth of the squares side

Step-by-step explanation:

t16 is the squares area and the area of a square is length X width, since all the sides of a square are equal, we can just take the square root of  16 which is 4 feet.

Answer:

3 out of 8

Step-by-step explanation:

Answer:

P(blue) = 3/8

Step-by-step explanation:

it waz correct. trust me

Answer:

We have to first see that the given lengths makes a triangle or not by using a+b > c in which a,b and c are

length of sides of a triangle lets check out

16 + 21 = 37 > 28

21 + 28 = 49 > 16

16+ 28 = 44 > 21

As because the statement fits correct in the lengths given so its a triangle

So we can say that the triangle is scalene by means of measurements

but cant be a right angle as by taking the pythagorean triplet

= a^2 + b ^ 2 = c^2

lets see if a=16, b = 21 and c = 28

So a^2 + b^2

= 256 + 441

= 697

but c^2

= 28^2 = 784

As 441 =/= 784

So The triangle lengths cant be a right angled triangle

So 1/2 of possibility is the traingle acute and 1/2 of the possibilty that the triangle is obtuse

Now you can find the correct triangle on the basis of acute or obtuse angle by drawing with given length of sides of triangle

Step-by-step explanation:

Answer:

it is an octagon; it is not regular

Answer:

1) 2400 sq feet

2) $93.75

3) A (first answer)

Step-by-step explanation:

1) replace the 6 inches with 60 feet and 4 inches with 40 feet. We do this bc 1 inch = 10 feet. Then multiply 60 x 40 to get 2400 sq feet

2) we know that 25% off of 100 is 75. Then to add 25% back to 75 we find 25% of 75. 25% of 75 is 18.75. So we add 18.75 + 75 to get $93.75

Step-by-step explanation:

(10-10) (10+2)

0 X 12=0

Answer:

0

Step-by-step explanation:

In order to solve this, we just substitute 10 instead of r, and get...

(r - 10)(r + 2) = (10 - 10)(10 + 2) = (0)(12) = 0
