Mila built a wooden toy bin with a lid to sell in her store. The bin is shaped like a rectangular prism and measures 2 feet long

charle [14.2K]

The rectangular prism having a length of 1 feet, width of 2 feet and that

is 1 feet deep, gives the area Mila stained as<u> 8 square feet</u>.

<h3>How can the area that Mila stained be found?</h3>

The given dimensions of the rectangular prism bin are;

Length of the bin = 2 foot

Width of the bin = 1 feet

Depth of the bin = 2 feet

Required:

The surface area of the rectangular prism bin.

Solution:

The surface area, S. A., of the rectangular prism bin is given as follows;

S. A. = Length × Width + Depth × Width + Length × Depth

Which gives;

S. A. = 2 × 1 + 2 × 1 + 2 × 2 = 8

The surface of area Mila stained, S. A. =<u> 8 ft.²</u>

Find two numbers whose sum is 114 and the difference is 58. <br> (written as an equation please)

diamong [38]

$⇒$

x + y = 114

x - y = 58

Add the equations downward:

2x + 0y = 172

2x = 172

x = 86

x + y = 114

86 + y = 114

y = 114 - 86

y = 28

Answer: The two numbers are 28 and 86.

The arc length, radius and the included angle are related as

$r\theta=\widehat {XYZ}$ where $\theta$ is in radians.

The radius $r$ is given by

$r=\frac{\widehat {XYZ} }{\theta} \\ r=\frac{10.8}{1.8} \\ r=6\;units$

Correct choice is (B).

What are the coordinates of each point after quadrilateral ABCD is reflected across the y-axis and then translated 2 units down?

dezoksy [38]

Answer:

$A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)$

Step-by-step explanation:

Given [Missing]

$A = (-3,4)$

$B = (1,3)$

$C =(3,6)$

$D =(1,6)$

The first transformation: reflection across the y-axis.

The rule is: $(x,y)==>(-x,y)$

So:

$A = (-3,4)$ ==> $A' = (3,4)$

$B = (1,3)$ ==> $B' = (-1,3)$

$C =(3,6)$ ==> $C' = (-3.6)$

$D =(1,6)$ ==> $D' = (-1,6)$

Translation 2 units down

The rule is: $(x,y)==>(x,y-2)$

So:

$A' = (3,4)$ ==> $A" =(3,4-2) =(3,2)$

$B' = (-1,3)$ ==> $B" = (-1,3-2) = (-1,1)$

$C' = (-3.6)$ ==> $C" = (-3,6-2) = (-3,4)$

$D' = (-1,6)$ ==> $D" =(-1,6-2) = (-1,4)$

Hence:

$A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)$
