What is the area of this ^2

Ad libitum [116K]

<h2>Question:- Area of the given diagram</h2>

<h2>Answer :- </h2>

Divide the diagram as shown in attachment.

Now first calculate the area of the rectangle having side 1 and 12

So area = length ×breadth

Area = 1× 12 = 12 unit²

Now find the Area of the remaining triangle with sides 12,13,5 units

$Area = \frac{1}{2} \times base \times height \:$

Now put the value as -> base= 5 and height= 12

$Area = \frac{1}{2} \times base \times height \: \\ Area = \frac{1}{2} \times 5 \times 12 \\ Area = \frac{1}{ \cancel2} \times 5 \times \cancel{12}^{ \: \: 6} \\ Area = 5 \times 6 \\ Area = 30 \: units^{2}$

Now add both areas for your answer

$Area{ \tiny{1}} = 12 {units}^{2} \\ Area{ \tiny2} = 30 {units}^{2} \\ Area{ \tiny{total}} = Area{ \tiny{1}} + Area{ \tiny{2}} \\ Area{ \tiny{total}} = 12 + 30 = 42 {units}^{2}$

Use properties of multiplication to show why 4 x 50 = 8 x 25.

nikdorinn [45]

Given:

$4\times 50 =8\times 25$

To find:

The steps to prove the given statement by using the properties of multiplication.

Solution:

We have,

$4\times 50 =8\times 25$

Taking left hand side, we get

$LHS=4\times 50$

$LHS=4\times (2\times 25)$

$LHS=(4\times 2)\times 25$ (Associative property of multiplication)

$LHS=8\times 25$

$LHS=RHS$

Hence proved.

Cindy and Zoey work at a store. Both girls earn $6.25 per hour

wolverine [178]

Answer:

Step-by-step explanation:

I think this is your full question, right?

<em>Cindy and Zoey work at a store. Both girls earn $6.25 per hour. During a normal week Cindy works 15 hours and Zoey works 20 hours. The expression 6.25(15) + 6.25(20) can be used to calculate the total amount of money that the girls earned in one week. Which expression shows another way to calculate the amount of money the girls earn in one week? </em>

My answer:

The expression shows another way must be equal to: <em>6.25(15) + 6.25(20) </em>

<=> 6.25 (15+20)

Because both girls earn the same per hour.

Needed help with a algebra 2 question if so...

erma4kov [3.2K]

Answer:

Quadrant II

Step-by-step explanation:

Since there are 360 degrees in a circle we will subtract it from 860 until we get a number less than 360

$860-360=500\\500-360=140$

Since it less than 180 but more than 90 it will be in the second quadrant

Hope this helps! <3
