Volume of a pyramid is (L * w * h) / 3

L=10 and w=10

h can be found by using the Pythagorean theorem:

divide the base by 2 and we get 5. Then we have that the hypotenuse is 13 and the bottom of the right triangle we formed is 5. a= sqrt(c^2-b^2)

a=h=12

we plug these numbers into the formula for the volume of a pyramid and get:

400

Which expressions are equivalent to the one below? Check all that apply.

V125BC [204]

Answer:

Step-by-step explanation:

The given expression is $10x$ .

We have to check which of he given options on simplification gives the same given expression.

(A) The expression is:

= $\frac{50x}{5x}$

= $10$

which is not equivalent to the given expression, thus this option is incorrect.

(B) The expression is:

= $10(10x)-1$

= $100x-1$

which is not equivalent to the given expression, thus this option is incorrect.

= $10(10x)+1$

= $100x+1$

which is not equivalent to the given expression, thus this option is incorrect.

(D) The expression is:

= $\frac{50x}{5}$

= $10x$

which is equivalent to the given expression, thus this option is correct.

(E) The expression is:

= $(\frac{50}{5})x$

== $10x$

which is equivalent to the given expression, thus this option is correct.

(F) The expression is:

= $x^5$

which is not equivalent to the given expression, thus this option is incorrect.

fgiga [73]

The scatter plot showing data gathered and line of best fit is attached below :

Answer:

Step-by-step explanation:

Given the regression model :

y = 1.73x + 0.0924

Where,

y = number of pink flowers

x = Red flowers

Slope = 1.73

Intercept = 0.0924

The number of pink flower that are predicted to bloom on a shrub of 40 red flowers :

Put x = 40 and calculate the value of y

y = 1.73(40) + 0.0924

y = 69.2 + 0.0924

y = 69.2924

Number of pink flowers = 69
