We want to find miles per hour.
Speed is distance over time.
So take 10 miles (distance) / 3 hours (time)
This is the same as 10/3.
10/3 = 3 and 1/3
Therefore, the girl is going 3 and 1/3 miles per hour.

Answer: 80 cookies

Step-by-step explanation: He had to bake 240 cookies and on Monday he baked have of them which is 120 cookies. Then on Tuesday he baked a third of the remaining so if the baked 120 and has to bake 240 he still has to bake 120 now 1/3 * 120 = 40 so he baked 40 cookies on Tuesday on Wednesday he still has to bake the reaming cookies so 120 + 40 = 160 and 240 - 160 = 80 so on Wednesday he has to bake 80 cookies.

Please answer this correctly

Answer:

<em>514 square meters</em>

Step-by-step explanation:

Consider the length of p;

$11 * p * 3 = 528,\\33 * p = 528,\\p = 528 / 33 = 16 meters$

11, 3, and p act as the length, width, and height of this rectangular prism. We can apply the volume formula length * width * height, and thus made 11 * p * 3 equivalent to the volume 528. Now let us determine the surface area;

$Area of Side 1 = 16 * 11 = 176 square meters,\\Area of Side 2 = 3 * 16 = 48 square meters,\\Area of Side 3 = 11 * 3 = 33 square meters,\\\\Surface Area = 2 * ( 176 ) + 2 * ( 48 ) + 2 * ( 33 ) = 352 + 96 + 66 = 514 square meters$

<em>Hope that helps!</em>

Express as a trinomial (2x+8)(x-3)

Luden [163]

Answer:

$\huge\boxed{(2x+8)(x-3)=2x^2+2x-24}$

Step-by-step explanation:

$\text{Use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\(2x+8)(x-3)=(2x)(x)+(2x)(-3)+(8)(x)+(8)(-3)\\\\=2x^2-6x+8x-24\qquad\text{combine like terms}\\\\=2x^2+(-6x+8x)-24\\\\=2x^2+2x-24$
