answer is 10.69 add the two values together
Answer:
6.7% decrease each day
Step-by-step explanation:
Half life: 10 days
Fraction = 0.5^(t/10)
Where t is the no. of days
Per day: t = 1
0.5^(1/10)
0.9330329815 × 100 = 93.30329917
Decrease of: 100 - 93.30329917
= 6.696700846% each day
Proving that EFGH is a square: points E,F,G,H
separate the sides of the square ABCD into two lines. if AE=BF=CG=DH then
AH=DG=EB=FC and it shows that if we connect the points E,F,G,H to each other with line we will have a square
HAE~EBF~FCG~GDH by rule SAS
Answer:
5/9
Step-by-step explanation:
Let the total number of buttons is x.
- Round buttons = 80% of x = 0.8x
- Square buttons = 0.2x
<u>Number of red buttons:</u>
- 0.1*0.8x + 0.5*0.2x =
- 0.08x + 0.1x =
- 0.18x
Number of red square buttons is 0.1x
<u>Required probability:</u>
- P = 0.1x/0.18x = 10/18 = 5/9
From the picture, the grass is only occupying the pink shaded area. Hence, we need to get the measurement of the pink shaded area only.
The formula for area of rectangle is A = L*W; where L= length and W = width
1.) Get the area of the whole landscape
A = 150 ft. * 100 ft.
= 15,000 sq. ft. is the area of the whole landscape diagram.
2.) Get the are of the other parts of the diagram
A = 20 ft. * 10 ft.
= 200 sq. ft. is the area of the white rectangle inside the diagram
A = 40 ft. * 30 ft.
= 1,200 sq. ft. is the area of the bigger grey-shaded rectangle
A = 20 ft. * 15 ft.
= 300 sq. ft. is the area of the smaller grey shaded rectangle
3.) Subtract the total measurement of the other parts from the measurement of the whole diagram
15,000 - (200+1,200+300) = 13,300 sq. ft.
4.) Therefore, A.) 13,300 sq. ft. is the area of grass in the home landscape diagram.
