Danielle built a ramp with a stopping block at the bottom for her scout troop's pinewood derby. She wants to paint the top and s

ides of the ramp. Danielle calculated the area by adding the areas of 2 triangular faces and 3 rectangular faces from the ramp and 6 rectangular faces from the block. Did Danielle calculate the area correctly? If not, what was her mistake? A. Yes, Danielle calculated the area correctly. B. No, Danielle needs to remove 1 rectangle from the ramp and 1 rectangle from the block. C. No, Danielle needs to add 1 triangle to the ramp and remove 1 rectangle from the block. D. No, Danielle needs to remove 1 triangle from the ramp and add 1 rectangle to the block.

Answer:

  B.  No, Danielle needs to remove 1 rectangle from the ramp and 1 rectangle from the block.

Step-by-step explanation:

It is true that the ramp has 2 triangular and 3 rectangular surfaces, and the block has 6 rectangular surfaces. However, Danielle doesn't want to paint the bottom rectangular surface of either the ramp or the block, so needs to remove one rectangle from each for her area computation.

which of the fallowing functions has a slope 3/2 and contains the midpoint segment between (6, 3) and (-2, 11)?
kolbaska11 [484]
Well, we know the slope is 3/2, what's the midpoint of those anyway?

\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
&({{ 6}}\quad ,&{{ 3}})\quad 
%  (c,d)
&({{ -2}}\quad ,&{{ 11}})
\end{array}\qquad
%   coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)
\\\\\\
\left( \cfrac{-2+6}{2}~~,~~\cfrac{11+3}{2} \right)\implies (2,7)

so, what's the equation of a line whose slope is 3/2 and runs through 2,7?

\bf \begin{array}{lllll}
&x_1&y_1\\
%   (a,b)
&({{ 2}}\quad ,&{{ 7}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{3}{2}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-7=\cfrac{3}{2}(x-2)
\\\\\\
y-7=\cfrac{3}{2}x-3\implies y=\cfrac{3}{2}x+4

5.) If all the edges of prism A are multiplied by 5 to create prism B. The volume of prism B will be __________ times the volume
zimovet [89]

Question:

If all the edges of prism A are multiplied by 5 to create prism B. The volume of prism B will be __________ times the volume of prism A?

* 5

* 125

* 50

* 25

Answer:

* 5 times.

Step-by-step explanation:

Let us represent all the edges of prism A as = X

Prism B = All the edges of Prism A × 5

Prism B = X × 5

= 5X

Let's assume the prism is a cube

Volume of a Prism(cube) = L × W × H

Volume of Prism A = L × W × H

Volume of Prism B = 5 (L × W × H)

Therefore, The volume of prism B will be 5 times the volume of prism A

Find the formula for the nth term of the sequence: 0,7,18,33,52​
defon

Answer:

t(n) = 2n² + n - 3

Step-by-step explanation:

<u>Given sequence: </u>

  • 0, 7, 18, 33, 52

Find the formula for nth term t(n)

<h3>Solution</h3>

<u>Sequence is neither arithmetic nor geometric, analyzing:</u>

  • 0, 7, 18, 33, 52

<u>First level difference</u>

  • 7, 11, 15, 19

<u>Second level difference</u>

  • 4, 4, 4

<u>As there are two levels, the formula should be in the form of:</u>

  • t(n) = an² + bn + c

<u>Trying the formula with the known terms:</u>

  • t(1) = 0 ⇒ a+b + c= 0
  • t(2) = 4a + 2b + c = 7 ⇒ 3a + b = 7
  • t(3) = 9a + 3b + c = 18 ⇒ 3(3a+b) + c = 18 ⇒ 21 + c = 18 ⇒ c = -3

<u>Going back to previous equations to find remaining coefficients:</u>

  • t(1) ⇒ a+ b = 3 ⇒ t(2) = 2a + (a+b) = 7 ⇒2a + 3 = 7 ⇒ a= 2 ⇒ b = 1

<u>So the formula becomes:</u>

t(n) = 2n² + n - 3

Oliver walks 5/8 of a mile in 1/6 of an hour. What is his unit rate in miles per hour?
stealth61 [152]

Answer:

3.75 miles per hour

Step-by-step explanation:

(5/8)/(1/6)=3.75 mph, or you could do 5/8 x 6, since 1/6 x 6 equals one hour
