Answer:
A. 320
Step-by-step explanation:
See attachment for the figure
in order to determine Area of quadrilateral ABDF, we'll use the formula i.e
Area of quadrilateral ABDF = Area of AECD - Area of ΔBCD - Area of ΔDEF ->eq(1)
whereas, area of AECD = (AC × AE)
Area of ΔBCD = 1/2 (BC x CD)
Area of ΔDEF =1/2 ( EF x ED)
Substituting in eq(1)
eq(1)=>
Area of quadrilateral ABDF = (AC × AE) - 1/2 (BC x CD)- 1/2 ( EF x ED)
=(32 x 20) - 1/2(16 x 20) - 1/2(10 x 32)
= 640 - 160 - 160
= 640 - 320
= 320 square unit
Therefore, the area of quadrilateral ABDF is 320 square unit
SO for 18 you would say Carla had $100 then spent $18 = $82, then she added $22 = $104 then she spent $53 so subtract that amount to get $51 in August.
Answer:
25% pay raise
Step-by-step explanation:
12.50-10.00=2.50
2.50/10.00=1/4
1/4=25%
<h3>The value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889</h3>
<em><u>Solution:</u></em>
<em><u>Given that:</u></em>
We have to find the value of expression
We know that,
Therefore,
We know that,
Similarly,
Thus value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889
