6. Sue goes to the bakery and purchases cupcakes and cookies for a picnic. She needs to serve 36 people. Cupcakes cost $2.50 eac

ruslelena [56]

Answer:the number of cupcakes that Sue purchased is 12

Step-by-step explanation:

Let x represent the number of cupcakes that Sue purchased at the bakery.

Let y represent the number of cookies that Sue purchased at the bakery.

She needs to serve 36 people. This means she would purchase a total of 36 people. Therefore,

x + y = 36

Cupcakes cost $2.50 each, cookies cost $1.00 each. She spends $54.00. This means that

2.5x + y = 54 - - - - - - - - - 1

Substituting x = 36 - y into equation 1, it becomes

2.5(36 - y) + y = 54

90 - 2.5y + y = 54

- 2.5y + y = 54 - 90

- 1.5y = - 36

y = - 36/ - 1.5

y = =24

x = 36 - y = 36 - 24 = 12

On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(1, 2). What is the length of Side RT

andriy [413]

Answer : 7 units

There are two ways you can solve this problem:

1st way - Subtract the T's x coordinate by r's x coordinate.

1-(-6) = 1+6 = 7

2nd way - Graph the points than count the units between them.

[I attached a picture, I graphed ur points]

Find the volume of the garden shed

Leno4ka [110]

Answer:

47.3 m³

Step-by-step explanation:

The garden shed is made up of a rectangular prism and a pyramid.

<h3><u>Volume of a rectangular prism</u></h3>

$\begin{aligned}\textsf{Volume of a rectangular prism}&=\sf width \times length \times height\\&=4 \times 4 \times 2\\&=16 \times 2\\&=32\;\; \sf m^3\end{aligned}$

<h3><u>Volume of a pyramid</u></h3>

<u />

From inspection of the given diagram, the slant height of the pyramid is 3.5 m.

Calculate the perpendicular height of the pyramid using Pythagoras Theorem:

$\begin{aligned}\implies a^2+b^2&=c^2\\2^2+h^2&=3.5^2\\h^2&=8.25\\h&=\sqrt{8.25}\;\; \sf m\end{aligned}$

Therefore:

$\begin{aligned}\textsf{Volume of a pyramid}&=\dfrac{\sf length \times width \times height}{3}\\\\&=\dfrac{\sf 4 \times 4 \times \sqrt{8.25}}{3}\\\\& = 15.31883372\;\; \sf m^3\end{aligned}$

<h3><u>Volume of the garden shed</u></h3>

$\begin{aligned}\implies \textsf{Volume of shed}&=\textsf{Volume of rectangular prism}+\textsf{Volume of pyramid}\\&=32+15.31883372\\& = 47.3\;\; \sf m^3\;(nearest\;tenth)\end{aligned}$
