Answer:
80
Step-by-step explanation:
we search for a square number so that rows*plantsInARow gives us the number
The number should be around 50², guessed
50² = 2500 (to low)
51² = 2601 (still to low)
52² = 2704 (bingo)
now to get from 2624 to 2704 plants he needs 80 more. That is the least number.
He could also go to plant 60² plants an than need slot more.
(would really appreciate the brainliest)
Answer:
5 m
Step-by-step explanation:
A model car is made to a scale of 1:50 (model: real).
If the model has a length of 10 cm, calculate the length of the real car (answer in meters).
We have a scale of :
model: real = 1:50
The model has a length of 10cm
Hence:
1 cm = 50 cm
10 cm = x cm
Cross Multiply
x cm × 1cm = 10 cm × 50 cm
x cm = 10 cm × 50 cm/1cm
x cm = 500 cm
The length of the real car is 500cm
Converting the length of the real car to meters
100cm = 1 m
500 cm = x m
Cross Multiply
100cm × x m = 500 cm × 1 m
x m = 500 cm × 1 m/100 cm
x m = 5 m
The Length of the real car in meters is 5m
Answer: B
Step-by-step explanation:
-9 - 6 - (-8) = -9 - 6 + 8 = -7
<span>The height of Gateway Arch shown on the Missouri quarter is 630 feet or 7,560 inches. Find how many 4 inch stacks of quarters make up the height of the Gateway Arch. If there are 58 quarter in 4 inch stack o, how many quarters high is the arch? </span>
<span>Hence to find how many 4 inch stacks of quarters make up the height of the </span><span>Gateway Arch,
Since the Gateway Arch is 7560 then for every stack is 4 inches to find the stacks all in all, we just have to divide 7560 / 4 = 1890
Then, to find </span><span>how many quarters high is the arch,
58 quarter x 4 inch = 232 quarters high in inches.
