Answer:

[tex]\sqrt{28}[/tex]

Step-by-step explanation:

It is given that the triangle (QRS) is right, thus one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states,

[tex](a)^2+(b)^2=(c)^2[/tex]

Where (a) and (b) are the legs or the sides adjacent to the right angle and (c) is the hypotenuse or the side opposite the right angle. The unknown side in the triangle is a leg, thus, let (b) represent this value. Substitute in the given values and solve,

[tex](6)^2+(b)^2=(8)^2\\\\36+b^2=64\\\\b^2=28\\\\b=\sqrt{28}[/tex]

Answer:

A

Answer:

10p squared ×3r

Step-by-step explanation:

2p ×3r×5p

group like terms

2p×5p×3r

10p squared × 3r

Answer:

Option C

Step-by-step explanation:

Given :-

And we need to find out the nature of the roots . The nature of the roots is determined by the Discriminant of the equation , and the Discriminant of a quadratic equation is ,

[tex]:\implies[/tex] Discriminant = b² - 4ac

[tex]:\implies[/tex] Discriminant = 2² - 4(1)(4)

[tex]:\implies[/tex] Discriminant = 4 -16

[tex]:\implies[/tex] Discriminant = (-12)

Now here the value of D is less than 0 .So the roots will be imaginary .

Hence the roots are imaginary and unequal.

Answer:

y=2/5x+8/5

Step-by-step explanation:

so say you plot a graph of rain against the hours the gradient would be the rate of change and the information given as your points and the gradient

now to get an equation of a straight line use one of your points eg(1,2) and the gradient or rate of change mine was 0.4

Answer:

Option C is your answer

Step-by-step explanation:

21,22,  23,  26,29,  32,  34,38,  40,  42,43

Yes, Q1 is 23, median is 32, Q3 is 40

So the box should start on 23, end on 40, and have its inner line over 32.

In your picture, that's option C

Answer:

[tex]A=200.96\ unit^2[/tex]

Step-by-step explanation:

Given that,

The circumference of the circle, C = 50.24 units

We need to find the area of the circle.

The formula for the circumference of the circle is given by :

[tex]C=2\pi r[/tex]

r is the radius of the circle

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{50.24}{2\times 3.14}\\\\r=8\ units[/tex]

The formula for the area of a circle is given by :

[tex]A=\pi r^2\\\\A=3.14\times 8^2\\A=200.96\ unit^2[/tex]

So, the area of the circle is equal to [tex]200.96\ unit^2[/tex].

hope this helps :)

Answer:

3, 3

Step-by-step explanation:

[tex]n^2 - 6n + 9 = 0 \\ n^2 - 3n - 3n+ 9 = 0 \\ n(n - 3) - 3(n - 3) = 0 \\ (n - 3)(n - 3) = 0 \\ n - 3 = 0, \: \: n - 3 = 0 \\ n = 3, \: \: n = 3[/tex]

Thus, the two numbers are 3, 3

Answer:

(-6,8)

Step-by-step explanation:

Answer: 142 degrees

mBC = 52

mCD = 90

90 + 52 = 142

It would most likely equal to 6. Hope this helped.

Step-by-step explanation:

Answer:

C is correct

Step-by-step explanation:

Firstly, we have to solve for x in the solution set of the inequality

We have this as follows;

x + 2 ≥ 6

x ≥ 6-2

x ≥ 4

To graph this, we consider the middle sign which is greater than or equal to

So, the inequality sign has to face the right side

secondly, it has to be shaded on the point 4 due to the fact that it has the ‘equal to’ beneath the single inequality symbol

so, the correct answer here is option C

Answer:

2.2 tons

Step-by-step explanation:

1 pound = 0.0005 tons

You have to multiply 4400 pounds by 0.0005 to get tons:

4400(0.0005) = 2.2 tons

Answer:

2.2 Tons

Step-by-step explanation:

You just have to see how many tons is in 4,400 pounds.

Answer: $156

Step-by-step explanation:

If a fishing reel had a markdown from $354 to $298, the percentage decrease will be:

= (354 - 298)/354 × 100

= 56/354 × 100

= 15.82%

Using thesame percentage decrease, when the price of a laptop is $185, the new price will be:

= (100% - 15.82%) × 185

= 84.18% × 185

= 0.8418 × 185

= 155.7

= $156 approximately
