Answer:

Step-by-step explanation:

firstly we must divide the shape like this

and the area of first rectangular is 27 m²( 9m × 3m)

then second rectangular's area is 48m²( 12m × 4m and we found 4m from 9-5)

the third rectangular's area is 10 m² ( we found it from 9-4)

Total is 27+48+10=85 m²

hope it helps

have a nice day

$different\ between\ \frac{5}{8}\ and\ \frac{1}{2}=\frac{5}{8}-\frac{1}{2}=\frac{5}{8}-\frac{4}{8}=\frac{1}{8}\\\\different\ between\ 1\ and\ \frac{5}{8}=1-\frac{5}{8}=\frac{8}{8}-\frac{5}{8}=\frac{3}{8}\\\\\frac{1}{8} \ \textless \ \frac{3}{8}\ therefore\ \frac{5}{8}\ is\ closest\ to\ \frac{1}{2}$

The graph represents the number y of attendees to a market research conference after x years.

Ok, I hope im right. (Others correct me if im not. But when I worked out this problem I got y is approximatly 4,882 attendees after 6 years.

Gathering info from the graph I created a table

(0,20) , (1,30) , (2,45), ...

I found the difference between the points listed. For example, 30÷20 is 1.5. So, each point is multiplied times 1.5 to continue the sequence.

Use the equation: y=a(1+r)^t

Remember what each variable stands for. That way you can plug in the correct information

Continuing..

y=a(1+r)^t

y=20(1+1.5)^t ; combine like terms

y=20(2.5)^t

b) Plug in the # of years. 6 in our case, everywhere you see a t

y=20(2.5)^6

y is approximately equal to 4882.8125

Round because we can only have whole numbers. we're talking about people.

I hope I got this right. But, if not, I tried

ONLY ANSWER THIS IF YOU HAVE AN EXPLANATION AND IF YOU KNOW WHAT THE ANSWER IS.

Semenov [28]

F) Tyler’s gray paint is a darker shade of gray than Hillary’s gray paint

When we take Tyler’s amount, we should do 8/30, which equals approximately .27. When we do the same thing with Hillary’s amount (10/40), we get .25. .27>.25, meaning that for the amount of white paint there is, more black paint is going into Tyler’s. As we know, black makes paint dark, so Tyler’s would be darker.

Answer:

1 4/5 = peanuts

1 1/5 = raisins

3/5 = chocolate chips

Step-by-step explanation:

3 ÷ 1 1/4 = 2 2/5

2 2/5 × 3/4 = 1 4/5

2 2/5 × 1/2 = 1 1/5

2 2/5 × 1/4 = 3/5
