Answer:

54.88cm

Step-by-step explanation:

For shaded region perimeter, subtract the circle perimeter from the rectangle

perimeter

= (10*8) - (2 * 3.14 * 8/2)

= 80 -  25.12

= 54.88cm

Given:

The given expression is:

[tex]\dfrac{3.6\times 10^7}{7.2\times 10^7}[/tex]

To find:

The value of the quotient.

Solution:

We have,

[tex]\dfrac{3.6\times 10^7}{7.2\times 10^7}[/tex]

It can written as:

[tex]=\dfrac{3.6}{7.2}\times \dfrac{10^7}{10^7}[/tex]

[tex]=\dfrac{1}{2}\times 1[/tex]

[tex]=0.5[/tex]

It can be rewritten as:

[tex]=5\times \dfrac{1}{10}[/tex]

[tex]=5\times 10^{-1}[/tex]

Therefore, the value of the quotient is [tex]5\times 10^{-1}[/tex].

Answer:

D)  1.0

Step-by-step explanation:

if y = 1 then x = 1

Answer:

A. -8

Step-by-step explanation:

Given the values of the function in a table, to determine the initial value of the function, you need to determine where x = 0.

Since the function is linear, the rate of change will be constant/the same.

To find the rate of change, you need to divide the change in the y value by the change in the x value.

X Y

+2↓ -5 | 7 ↓ -6

+2↓ -3 | 1 ↓ -6

+2↓ -1 | -5 ↓ -6

1 | -11

_____________

Since y changes by -6 and x changes by +2 every time, ∆Y/∆X = -6/+2 [Reduce] = -3/+1.

Slope = -3.

This means that y will decrease by 3 units every increase of 1 unit in x.

If (-1, -5) is a point which means that -1 is x when -5 is y.

We can apply the rate of change to see where x = 0.

So -5 + 1(-3/+1) → -5 + -3 = -8

=12.36/6

=2.06cm

Therefore, the answer is 2.06cm

Answer:

5.0003 x 10^-5

I believe this is the answer!

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive. Hope this helps!

Step-by-step explanation:

5/6+1/15+1/12in on minute

Emma's best record is 59/60 kilometers per minute.

Given that, Emma personal record was 5/6 of a kilometer in one minute.

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Given, after six months, she improved her record by 1/15 of a kilometer. After a year, she further improved her record by 1/12 of a kilometer.

Now, 5/6 + 1/15 + 1/12

LCM of denominators 6, 15 and 12 is 60.

50/60 + 4/60 + 5/60

= 59/60

Therefore, Emma's best record is 59/60 kilometers per minute.

Answer:

B

Step-by-step explanation:

Hi,

2πr is the formula for circumference, you know your diameter is 4cm and radius is half of the diameter, so your radius is 2cm.

To find the circumference, you have to multiply 2 by 2 and pie. 2 x 2 is 4. So 4 times pie. B is your correct answer.
