Answer:

Step-by-step explanation:

Given: 8 chocolate chip cookies, 9 peanut butter cookies, 5 sugar cookies and 7 oatmeal cookies.

=> Total cookies are: 29

  • The possible outcomes of sugar cookie: C^{1} _{5} = 5 and the total possible outcomes: 25
  • The possible outcomes of oatmeal cookie: C^{1} _{7} = 7 the total possible outcomes 25-1 =24 because Catherine eats it

The probability that Catherine randomly selects a sugar cookie from the bag, eats it, then randomly selects an oatmeal cookie:

P(sugar then oatmeal) = \frac{5}{25} \frac{7}{24} = \frac{7}{120} = 0.058

A cyclist can cover a distance of 18 miles in 45 minute. How many miles the cyclist can cover in 6 hours?
kolbaska11 [484]

First, lets find how many miles the cyclist can ride per minute (speed = distance/time).

18/45 = 0.4 miles per minutes

Second, lets find how many miles the cyclist can ride per hour.

0.4 * 60 = 24 miles per hour

Third, lets find how many miles teh cyclist can ride in 6 hours.

24 * 6 = 144 miles in 6 hours

Best of Luck!

There are 4 grid lines between 0 and 1 in each direction, so each grid line represents 1/4 unit. Two of them is 1/2 unit; 3 of them is 3/4 unit. The x-dimension is listed first in the ordered pair.

Point S has coordinates (-3/4, 1/2).

Which zero pair could be added to the function fon) = x2 + 12x + 6 so that the function can be written in vertex form?
Oksanka [162]

ANSWER

36,-36

EXPLANATION

The given function is:

f(x) =  {x}^{2}  + 12x + 6

To write this function in vertex form;

We need to add and subtract the square of half the coefficient of x.

The coefficient of x is 12.

Half of it is 6.

The square of 6 is 36.

Therefore we add and subtract 36.

Hence the zero pair is:

36, -36.

The correct answer is D.

Answer: OPTION D

Step-by-step explanation:

The formula for calculate the surface area of a rectangular prism is:

SA_{rp}=2(wh+lw+lh)

Where w is the width, h is the height and l is the length.

You can see in the figure attached that:

l=3.4ft

w=3ft

h=4.1ft

Therefore, when you substitute these values into the formula you obtain that the surface area is:

SA_{rp}=2[(3ft*4.1ft)+(3.4ft*3ft)+(3.4ft*4.1ft)]=72.88ft^{2}
