Below is the solution:
C = number of Cube
P = number of pyramids 
You may utilize either substitution or end. 
6C + 5P = 95 
5C + 5P = 85 


C = 10

Answer with Step-by-step explanation:

We know that number of sides in cube=6

and number of sides in pyramid=5

Let there be c cubes and p pyramids.

The total number of objects in the box is 17.

⇒ c+p=17

⇒ p=17-c

The total number of sides for the cubes and pyramids is 95.

⇒ 6c+5p=95

⇒ 6c+5(17-c)=95

⇒ 6c+5×17-5c=95

⇒ c+85=95

⇒ c=95-85

⇒ c=10

Hence, number of cubes in box are:

10

What does the fraction 5/6 mean? Show how it can be written using division.
Veseljchak [2.6K]
5/6 means 5 out of 6 items. 5/6 can also be written as 0.83 (the three never ending). This means 5 out of 6 things is 83% of the total.

The scatterplot shows the relationship between the number of slices of pizza eaten by each member of a football team (x) and the
ivolga24 [154]

Answer:

5.31

Step-by-step explanation:

Given the regression line equation, y = 10 - 0.67x, where,

x = number of slices of pizza eaten

y = number of laps run immediately

Number of laps run by a player who ate 7 slices of pizza can be predicted by plugging in x = 7 into the regression line equation to find y:

y = 10 - 0.67x

y = 10 - 0.67(7)

y = 10 - 4.69

y = 5.31

9. Write an equation parallel to y = 2x + 4that<br> passes through the point (-4,-1).
sasho [114]

Answer:y=2x+7

Step-by-step explanation:

so for the new equation, we know the slope is going to be the same (because its parallel) so for starters we have y=2x+b so now in order to find b (the y-intercept) we have to plug the point into the equation. So it would look like -1=2(-4)+b and then you solve for b and get 7 for b. SO the final answer is y=2x+7.

Item 18 A spherical ball with a volume of 972π in.3 is packaged in a box that is in the shape of a cube. The edge length of the
alexandr402 [8]
Check the picture below.

so, the diameter of the sphere, is the same as a side's length of the cube, bearing in mind that all sides in a cube are the same length.

since all sides in the cube are "d", then its volume is V = d*d*d or V = d³.

\bf \textit{volume of a sphere}\\\\&#10;V=\cfrac{4\pi r^3}{3}~~&#10;\begin{cases}&#10;r=radius\\&#10;-----\\&#10;V=972\pi &#10;\end{cases}\implies 972\pi =\cfrac{4\pi r^3}{3}\implies 2916\pi =4\pi r^3&#10;\\\\\\&#10;\cfrac{2916\pi }{4\pi }=r^3\implies 729=r^3\implies \sqrt[3]{729}=r\implies \boxed{9=r}

since the diameter is twice as much as the radius, thus d = 2r, or namely d = 18.

therefore, the volume of the cube will be V = 18³.
