3/4 25% 2.8x10
Step-by-step explanation:
Use Phythagoras Theorem!!
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

I need help with square roots. I would really appreciate it if you help me understand them. Thank you! I'll give you 10 points and a five star review for a good answer.
Answer: 9/8
Step-by-step explanation:
The square root of this is 9/8 because when you square 9/8, you get 81/64, and when you square root it, you get 9/8.
The easiest way tho is knowing that when you square a number and square root the square, you get the same number, cuz the square root cancels the square. Does that make sense?
Anyways hope this helped!

Part 1 out of 2
Complete and solve the equation that can be solved to find the number of hours for which the total cost
will be the same for the two services. In your equation, use x to represent the number of hours of dog
sitting
The equation is
The total cost will be the same for the two services at
hours.
Answer: both services will cost the same if it is for 3 hours service.
Step-by-step explanation: Hope this helps.
Define x: Let x be the number of hours
Derrick Dogs sitting:
Fixed charged=$12
Hourly change=$5
Total charge=12+5x
Darlene dog sitting:
Fixed charged=$18
Hourly change=$3
Total charge= 18+3x
Find the total number of hours so that both cost are the same:
12 + 5x = 18 + 3x
5x - 3x = 18 - 12
2x = 6
x = 3
ANSWER: both services will cost the same if it is for 3 hours service
Answer:
3 hours hon

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
