QveST [7]

The question has missing details

The missing options are:

A. 188,000 square yards

B. 138,000 square yards

C. 600 square yards

D. 300 square yards

See attachment 1 for the missing diagram

Answer:

B. 138,000 square yards

Step-by-step explanation:

The figure can be divided into two shapes (see attachment 2)

From attachment 2,

The dimension of the big rectangle is 1300ft by 800ft

The dimension of the small rectangle is 500ft by 400ft

So, the area is:

Area of the big rectangle added to the area of the small rectangle

i.e.

$Area = 1300 * 800 + 500 * 400$

$Area = 1040000 + 200000$

$Area = 1240000ft^2$

Convert to $yd^2$ by dividing by 9

$Area = 1240000yd^2 /9$

$Area = 137777.777778\ yd^2$

From the list of given options, the closest to the area of the diagram is

B. 138,000 square yards

Type the correct answer in each box. The reflection of point S across the y-axis is point . The reflection of point Q across the

tresset_1 [31]

Answer:

$S' = (-5,-5)$

$Q"=(-5,-5)$

Step-by-step explanation:

Given

$S = (5,-5)$

$Q= (5,5)$

Solving (a): Reflect S across y-axis

The rule to reflect across y-axis is:

$(x,y) \to (-x,y)$

So, we have:

$S(5,-5) \to S'(-5,-5)$

Hence:

$S' = (-5,-5)$

Solving (b): Reflect Q across x and y-axis

The rule to reflect across x-axis is:

$(x,y) \to (x,-y)$

So:

$Q(5,5) \to Q'(5,-5)$

The rule to reflect across y-axis is:

$(x,y) \to (-x,y)$

So:

$Q'(5,-5) \to Q"(-5,-5)$

Hence:

$Q"=(-5,-5)$

I don’t understand at all

mariarad [96]

A=1/2ab
Replace the variables with their value
15=1/2(3/2)b
Multiply 1/2 and 3/2
$\frac{1}{2} \times \frac{3}{2 } = \frac{3}{4}$
15=3/4b
Divide 3/4 on both sides
15/(3/4) is the same thing as
$\frac{15}{1 } \times \frac{3}{4} = \frac{45}{4}$
45/4=b
