I'm sorry if I get this wrong, but there isn't enough evidence.
If we think about the shorter side being 4.2 cm, then just divide 33.6 by 4.2 to give it a ratio. 33.6 / 4.2 is 8. The ratio of the scale drawing to the actual playground would be 1 : 8.
The longer side is 10.5, so just multiply that by 8. You'd get 84 meters. The only part left is getting the area.
Multiply 84 x 33.6 and you'd get 2822.4
The answer would be 2,822.4 squared.

Four friends took a road trip that lasted 50 hours round trip. Denny drove five times as long as Connor, while Pat and Seth drove the same amount of time. Connor drove half as long as Pat. How long did Denny drive?
Answer:
Denny drove for 25 hours
Step-by-step explanation:
Here, we want to calculate the amount of time Denny drove
Let the time Connor drove be c
Denny drove 5 times as this which is 5 * c = 5c
Conor drove half as long as Pat
So this means that Pat drove 2 times Conor = 2c
Seth is same as Pat which is also 2c
Adding all gives 50
c + 5c + 2c + 2c = 50
10c = 50
c = 50/10
c = 5 hours
Denny = 5 * c
= 5 * 5 = 25 hours
GUYS PLEASE HELP I MARK BRAINLIEST 5 STARS IM SORRY ABOUT THE POINTS I ONLY HAVE 13 Andre’s school orders some new supplies for the chemistry lab. The online store shows a pack of 10 test tubes costs $4 less than a set of nested beakers. In order to fully equip the lab, the school orders 12 sets of beakers and 8 packs of test tubes.
Write an equation that shows the cost of a pack of test tubes, t, in terms of the cost of a set of beakers, b.
t=b-4
The school office receives a bill for the supplies in the amount of $348. Write an equation with t and b that describes this situation.
b+t=348
Since t is in terms of b from the first equation, this expression can be substituted into the second equation where t appears. Write an equation that shows this substitution.
b+(b-4)=348
b=176
How much did the school pay for a set of beakers? $____
How much did the school pay for a pack of test tubes? $____
Answer:
this is not originally by me
Step-by-step explanation:
10t = b - 4
12b+8t = $348
This is a system of equations. I’ll be solving through substitution.
In the first equation. solving for b (the easier variable to isolate) gives you:
b = 10t + 4
Substitute this into the second equation:
12(10t+4) +8t = 348
120t+48+8t = 348
128t = 300
t = 2.34375 —> round it to the nearest cent to get 2.34 dollars
b = 10t+4
b = 10(2.34)+4
b = 27.4 dollars
Can anyone please help me solve this??

Shayla tutors middle school students and high school students. She charges a different rate for each. Last week, she tutored middle school students for 5 hours and high school students for 12 hours. This week, she tutored middle school students for 6 hours and high school students for 10 hours. She earned $400 last week and $370 this week. How much does she charge each?
Answer:
Shayla charges $20 per hour for middle school students and $25 per hour for high school students.
Step-by-step explanation:
System of Equations
Let's call:
x = Shayla's hourly charge for middle school students
y = Shayla's hourly charge for high school students
Last week, Shayla tutored middle school students for 5 hours and high school students for 12 hours. The total earning was 5x+12y. She earned $400 last week, thus:
5x + 12y = 400 [1]
This week, she tutored middle school students for 6 hours and high school students for 10 hours. The total earnings were 6x+10y and it represented $370, thus:
6x + 10y = 370
Dividing by 2:
3x + 5y = 185 [2]
We have formed the system of equations:
5x + 12y = 400 [1]
3x + 5y = 185 [2]
Multiply [1] by -3 and [2] by 5:
-15x - 36y = -1200
15x + 25y = 925
Adding both equations:
-11y = -275
Dividing by -11:
y = -275/(-11) = 25
y = 25
Substituting in [1]:
5x + 12*25 = 400
5x + 300 = 400
5x = 400 - 300 = 100
x = 100/5 = 20
x = 20
Shayla charges $20 per hour for middle school students and $25 per hour for high school students.

the length pf a rectangle is 50 cm and its diagonal is 51 cm. work out the area of the rectangle, to the nearest square centimetre.
a² + b² = c²
50² + 51² = c²
2500 + 2601 = c²
5101 = c²
√5101 ≈ 71.42 cm.
Answer: Area of the rectangle = 102.5 cm² Round to 103 cm²
Step-by-step explanation:
The diagonal is the hypotenuse, c So subtract the square on the base (length) to find the altitude (height).
a² + b² = c²
a² + 50² = 51²
a² = 51² - 50²
a² = 2601 -2500
a² = 101 take the square root of both sides
a = √101
a = 10.04987562 Round to 10.05
Area = LW
Area = 50 × 10.05
Area = 102.5 cm² Round to 103 cm²

im marking brainliest who ever answers this
Answer:
84%
Step-by-step explanation:
[tex]\frac{21}{25}[/tex]
25 needs to be equal to 100, so it would need to be multiplied by 4.
So, do the same thing the numerator 21.
[tex]\frac{84}{100}[/tex]
84/100 is equal to 84%
Answer:
[tex]\frac{21*4}{25*4} =\frac{84}{100}=84%[/tex]%
