Answer:

2.75

Step-by-step explanation:

So to figure this out, lets start by converting it into a inproper fraction.

So we know that the whole number is 7, and the denominator is 16, so we need to multiply them together to make our fraction improper:

7*16

=

112

Now add the 9 from what we already had of the fraction:

112+9

=

121

So our improper fraction is:

121/16

Now we must find the square root.

So to find the square root of a fraction, you have to take the square root of both the numerator and the denominator.

The square root of 121 is 11. We know this because 121 is a perfect square, and 11*11 makes 121.

The square root of 16 is 4. We know this as well because 16 is also a perfect square, and 4*4 makes 16.

So the square root of 121/16 is now:

11/4

If you need to, you can convert this into a mixed fraction or a decimal.

4 goes into 11, 2 times with a remander of 3. So:

2 3/4.

3/4 is equivelent to 0.75, so this can also be:

2.75

This is your answer!

Hope this helps!

Answer: Its 5.71%

Step-by-step explanation:

Answer:

The park formed like a rectangle so :

Area = length × width

Area = ( 9/10 ) × ( 4/5 )

Area = 9 × 4 / 10 × 5

Area = 9 × 2 × 2 / 5 × 5 × 2

Area = 18 / 25

Answer:

44.

Step-by-step explanation:

Given expression: [tex]3t^2-t[/tex]

To find the value of [tex]3t^2-t[/tex] where t = 4, we need to substitute t for 4 in the expression.

After substituting, we use PEMDAS (the order of operations) to solve. This is because this problem includes multiple operations.

[tex]3(4)^2-4[/tex]

[tex]=3(16)-4[/tex]

[tex]=48-4[/tex]

[tex]=48-4=44[/tex]

[tex]\to \inft3(4)^2-4=44[/tex]

Therefore, the value of [tex]3t^2-t[/tex] is 44, when t = 4.

Answer: [tex]x^2+\frac{11}{4}x+\frac{3}{2}[/tex]

Step-by-step explanation:

Use FOIL:

[tex]x^2+\frac{3}{4} x+\frac{4}{2} x+\frac{12}{8}[/tex]

[tex]x^2+\frac{3}{4} x+\frac{8}{4}x+\frac{12}{8} \\[/tex]     Make 3/4x and 4/2x have the same denominator

[tex]x^2+\frac{11}{4}x+\frac{12}{8}[/tex]            Add like terms

[tex]x^2+\frac{11}{4}x+\frac{3}{2}[/tex]              Simplify

Estimate the following product in scientific notation, and then select the best answer for the product's power of 10

(91x10²) ÷ (3.3 x10¹²)

Answer:

2.75 ×10^-9

Step-by-step explanation:

Estimate the following product in scientific notation, and then select the best answer for the product's power of 10

(91x10²) ÷ (3.3 x10¹²)

= (91 × 10²) / (3.3 × 10¹²)

= (91 × 10²) / (33 × 10¹¹)

= 91/33 × ( 10^2 - 11)

= 2.757575757 × 10^-9

Approximately

= 2.75 × 10^-9

Answer:

0.25

Step-by-step explanation:

1) the probability for Spinner-1 is:

1/3;

2) the probability for the Spinner-2 is:

3/4;

3) the required probability for the Spinner-1 and the Spinner-2 is (should be used the rule logical 'AND'):

1/3 * 3/4 = 1/4=0.25

Answer:

y = x

Step-by-step explanation:

i took two points which are very close to the trend line - (3,3) and (5,5) - to get the slope

the slope is 2/2 or 1 and the y-intercept is zero

this means the trend line is 'y = x'

Answer:

A

Step-by-step explanation:

If you use BIDMAS or BODMAS the first rule is brackets and inside the brackets you add and is therefore the first operation to use.

Answer:

D. Zero product property of multiplication

Step-by-step explanation:

The property of real numbers that Felipe used for step 2 is Zero product property of multiplication.

The zero product property of multiplication states that if any two factors of an algebraic expression is multiplied together and equated to zero, at least one of the expressions is equal to zero.

In the above question, factorising the algebraic expression above, we have two factors:

(x+2) and (x+4),

(x+2) (x+4) = 0

Hence,

x+2 =0 or X+4=

Therefore, Option D is correct.

Round this value however you need to. The exact length is sqrt(319)

In other words, sqrt(319) = 17.8606

=======================================================

Work Shown:

Apply the pythagorean theorem to solve for b.

a^2+b^2 = c^2

9^2 + b^2 = 20^2

81 + b^2 = 400

b^2 = 400-81

b^2 = 319

b = sqrt(319)

b = 17.8606 which is approximate

I'm going with the approximate value it makes more sense to do so in this case. Saying "the length is sqrt(319)" to someone not familiar with math, would probably not convey just how long the third side must be. Round the value in bold however you need to.

Answer:

19 Five is not tangent to the circle.

20 Eight is tangent to the circle.

Step-by-step explanation:

In order for one of the legs to be a tangent to a circle, the length must be part of a right angle triple.

I don't think the diagram on the left is, but I'll check it.

5^2 + 12^2 =

25 + 144 =

169

square root of 169 is 13

The length of the hypotenuse should be 13 not 14. Fourteen does not make Pythagorean triple. 13 would. So the line 5  units long does not make a tangent to the given circle.

The diagram on the right is a different story. 6 8 and 10 do make a Pythagorean triple, even though the two diagrams are not the same.

The radius and the distance to the external point  form a right angle.

The Pythagorean triple is

6^2 + 8^2 = 10^2

36 + 64 = 100  

100 = 100
