Tyler is designing a banner that will welcome people to a festival. The design for the banner has an
area of 1.5 square feet. The actual banner will be a dilation of the design by a factor of 5. What will
the area of the actual banner be?
Answer:
7.5 sq ft
Step-by-step explanation:
1.5*5=7.5
The design is 1/5 of the actual size, so you just multiply by 5 to get the real size.
Need help ASAP please--about estimate. which answer is correct. Please give me an opinion. Three students were asked to use estimation strategies to find a reasonable solution to this question: Ricky had 26 stickers before buying 7 from the store. Then he gave 8 to his sister. Estimate how many stickers he has left. From the choices below, select the student with the most reasonable solution.
a) Student A: Ricky has around 45 stickers left. Round 26 stickers to 40, 7 bought to 10, and 8 given to 5. Add 40 + 10 to get 50. Then subtract 50 − 5 to get the estimated answer of 45.
b) Student B: Ricky has around 30 stickers left. Estimate the sum of 6 from the 26 stickers plus 7 bought to be about 20. Add the 20 to the leftover 20 to get 40. Round 8 given to 10. Then subtract 40 − 10 to get the estimated answer of 30.
c) Student C: Ricky has around 10 stickers left. Estimate the sum of 6 from the 26 stickers plus 7 bought to be about 10. Add the 10 to the leftover 10 to get 20. Round 8 given to 10. Then subtract 20 − 10 to get the estimated answer of 10.

tmara is making a medium length necklace. write an expression that shows how nuch it will cost tamara for the chain,pendant,and b beads that cost $0.25 each.Then find the total cost of the necklace if tamara uses 30 beads.
Answer:
1/4(n), $7.50
Step-by-step explanation:
Expanded: cost = 0.25 * chains + 0.25 * pendants + 0.25 * beads
Simplified: c = (1/4)(total number of items)
Expression only: 1/4n where n = # chains + # pendants + # beads purchased
Total cost of 30 beads = 1/4(30) = 7.5 = $7.50

Jamal has 30 ounces of a 20% saline solution. This means 20% of the solution is salt. He combines this solution with 25 ounces of a 30% saline solution.
What is the total amount, in ounces, of salt in the combined mixture? Please help and please provide an explanation?
Answer:
12.5 or 12 1/2 (may be wrong)
Step-by-step explanation:
First I set up a formula to solve how many ounces of salt there were out of 30,
x/30=20/100, I crossed multiplied and got 5/30, next, I set up the same formula for how many ounces of salt there were out of 25, x/25=30/100, I got 7.5, the last thing I did was add them both together leading me to the answer 12.5 or 12 1/2. Hope this helps! Please say if I am wrong.

One shirt is represented as “y”
He ordered four shirts totaling $44
y+y+y+y =$44
Answer:
1. x = 462.30m
2. c
Step-by-step explanation:
1. Let "x" represent how much Samantha earns, and "m" represent how many months she has worked.
Because she makes $462.30 per month, if we multiply that by "m" then we will get x.
2. Kyle spend $44 on four sweaters total, which would make the total cost be evenly distributed into 4 sections.

Step-by-step explanation:
what is the measure of angle b
Answer:
34
Step-by-step explanation:
A triangle will add up to a degree of 180, so if you add those 2 angles then subtract it from 180 you will get the answer. So, 115+31=146 then 180-146=34
So the answer is 34
Answer:
b = 34 degrees
Step-by-step explanation:
*triangles have an interior angle of 180 degrees
to find b, take the known angles (115 and 31) add them together and subtract the sum from 180:
⇒ 180 - (115 + 31)
solve:
⇒ 180 - 146 = 34
b = 34

If there are 150 people born in the world every minute; how
many are born every Hour? Day? Year?
Step-by-step explanation:
150 x 60 = 9,000 every hour
9000 x 24 = 216,000 every day
216000x 365 = 78,840,000 every year
Answer:
Hour: 9,000 people
Day: 216,000 people
Year: 78,840,000 people
Step-by-step explanation:
In order to solve this, you need to identify how many minutes there are in an hour, a day, and a year:
Hour: 60 minutes
Day: 60 minutes × 24 hours = 1,440 minutes
Year: 60 minutes × 24 hours × 365 days = 525,600 minutes
Now, you need to multiply each of these numbers by 150 to find how many people are born every hour, day, and year:
Hour: 60 minutes × 150 people = 9,000 people
Day: 1,440 minutes × 150 people = 216,000 people
Year: 525,600 minutes × 150 people = 78,840,000 people

What is the relationship between the two triangles at right? Create a flowchart to justify your conclusion.
Answer:
[tex]3^{2}+4^{2}=JH^{2} \\\\9+16=25=JH^{2} \\\\JH=\sqrt{25} =5\\\\[/tex]
[tex]AB^{2} +6^{2} =10^{2} =100\\\\AB^{2} =100-36=64\\\\AB=\sqrt{64}=8\\[/tex]
all three pairs of appropriate sides of a triangle are proportional, the ratio is the same.
10/5=8/4=6/3=2 so the triangles are similar

Find value of x
Find value of y
Answer:
Step-by-step explanation:
use SOH CAH TOA
Sin = Opp / Hyp
Cos = Adj / Hyp
Tan = Opp / Adj
then we know the adjacent side and the angle, and want to find the Hyp, so use CAH
Cos(60) = ( 8[tex]\sqrt{3}[/tex] / 3 ) / Hyp ( cos(60) = 1/2 )
Hyp = (8[tex]\sqrt{3}[/tex] / 3) / (1/2)
Hyp = 2 ((8[tex]\sqrt{3}[/tex] / 3)
Hyp = 16[tex]\sqrt{3}[/tex] / 3
x = 16[tex]\sqrt{3}[/tex] / 3
Now use SOH
Sin (60) = Opp / 16[tex]\sqrt{3}[/tex] / 3 ( sin(60) = [tex]\sqrt{3}[/tex]/2 )
(16[tex]\sqrt{3}[/tex] / 3)([tex]\sqrt{3}[/tex]/2) = Opp
16 * 3 / 6 = Opp
8 = Opp
y = 8

I need help and please give me an understandable answer because I need to go to bed right now. I used 31 and 40 feet and none of them worked
Answer:
35 feet
Step-by-step explanation:
We'll begin by calculating the resultant for you and your friend.
For you:
R² = 12² + 9²
R² = 144 + 81
R² = 225
Take the square root of both side
R = √225
R = 15 feet
For your friend:
R² = 16² + 12²
R² = 256 + 144
R² = 400
Take the square root of both side
R = √400
R = 20 feet
Finally, we shall determine the distance between you and your friend.
The distance between you and your friend is obtained by adding your resultant and that of your friend together i.e
You resultant = 15 feet
Your friend's resultant = 20 feet
Distance between you and your friend = 15 + 20 = 35 feet.
Therefore, you threw the baseball 35 feet away from your friend.
The graph below models the changes in temperature of a liquid during a laboratory experiment what point of the graph represents the final temperature?
Answer:
J
Step-by-step explanation:
Since the final tempurature means the final point of the line, you can see the point that ends is on (7, 0). The order for coordinate points is (x, y) and the point ends on 7 on the x-axis and 0 on the y-axis. Hope this helped!
