The circle at the right represents a planet. The radius of the planet is about 4700 km. Find the distance d to the horizon that a person can see
on a clear day from the following height h above the planet
h=2 km
A person can see a distance of approximately km on a clear day from a height of 2 km above the given planet.
Answer:
137.13km
Step-by-step explanation:
A right triangle is formed, where h + r = 2+ 4700= 4702 km is the hypotenuse, r = 4700km is one leg and d is the other leg. By Pythagorean theorem:
4702² = 4700² + d²
d² = 4702² - 4700²
d = √18,804
d = 137.13 km

I have 12 more nickels than quarters. It the coins are worth $5.40, then how many of each type
of coin do I have?
Answer:
You have 16 quarts and 28 nickels lol
Step-by-step explanation:
Answer:
16 quarters and 28 nickels
Step-by-step explanation:
Because...
1 quarter=25 cents of so if you have 16 quarters that=4.00$
2 if there are 12 more nickels then there are 28 nickels.
1 nickle=5 cents. so what is 28 x 5=1.40$
Then add 4.00$+1.40$=5.40$ and there is your answer.
Hope this helps have a great day:)
alright so I got the answer from here but I still can't figure out how we got 12p? can somebody explain step by step pls
There's no 12p in the simplification

You bought a car for $5,000. Each year it appreciates in value by 8.5%. Which equation can be used to find the value, v, of the car, x years after it was purchased?\
The equation that represents the value of the car is v = $5000(1.085)^x.
What equation represents the value of the car?Appreciation means when the value of a car increases with the passage of time. The formula that can be used to represent appreciation is:
FV = P (1 + r)^n
Where:
FV = Future value P = Present value R = interest rate N = number of years
V = 5000(1.085)^X

sukhleen is making a chess board she has 210cm2 of wood with which to make the white squares 210cm2 of wood with which to make the black squares and 6500mm2 of word to make a border
what is the total area of the chessboard?
Answer: 1070cm2
Step-by-step explanation: Hi there
(Not taking the number of squares into account)
1. Convert 6500 millimeters to centimeters
6500mm=650cm
2. Add the area of the wood
650+210+210=1070
So the total area is 1070 cm2
Have a nice day! :)

-10+4(2b+2)=
Answer:
2(4b-1)
Step-by-step explanation:
1. You would have to distribute first. So basically you just multiply 4 · 2b which gives you 8b and then 4 · 2
Answer to first step: -10+8b+8
2. Add the numbers. It should be -10 + 8 which would give you -2
Answer to second step: -2 + 8b
3. Rearranging the terms. So, instead of doing -2 + 8b you would have to do 8b - 2
Answer to third step: 8b - 2
4. 2(4b - 1) Find what times what gives you 8 (not 1 times 8) and the same for -2

Find the co-interior angle measurements for the measured angle.
Thanks! :)
Answer:
71°
Step-by-step explanation:
Line AB is parallel to line CD and that makes the angle given as 109 and the co-interior angle supplementary
since the sum of supplementary angles is equal to 180° :
180 - 109 = 71 is the measure of the co-interior angle
How can you use estimation to find
92 +91 +92 +91 +9?
Answer:
370
Step-by-step explanation:
Round each answer into easier to add numbers. 92 and 91 round down to 90. 9 rounds up to 10.
Answer:
aprox 280
Step-by-step explanation:
if you need to add these numbers quickly you can estimate either with an overestimation or under estimation:
for an over estimation, you can find the nearest 10 or 100 that each value is so for this you have 92 + 91 +92 +9 which is close to 100 +100+100+10
so using this you can quickly guess that it would be somewhere around 310
for an under estimation you can do the same thing but rounding down so we instead would add 90 + 90 + 90 + 10 which gives 280
now using both we know the answer would be somewhere between 280 and 310

Sophia is designing the seating arrangement for a concert and
outdoor theater. To give everyone a good view, each row must have 8
more seats than the row before it, and the 1st row can only have 13
seats. Help Sophia plan the rest of the seating by solving for how many seats are in row 20. Then explain to Sophia how to create an equation to predict the number of seats in any row.
Answer:
the answer for the first part is 260
the equation is n+8
Step-by-step explanation:
all you need to do is take the starting number witch is 13 then you add 8 and then take that number and add 8 so thats why the equation is n+8 n equaling the starting number and 8 equaling to the reoccurring number.

5x - 7 < 13
Answer:
5x-7 has to equal to something smaller than 13
5x-7=5
Answer: x < 4
Step-by-step explanation:
Disregarding the lesser than sign, we can treat this equation as 5x-7=13. This doesn't work all the time as there are rules, but those rules don't apply to a simple inequality such as this.
5x-7<13
5x<20
x<4
And so, our answer is x<4

Maria is building a circular pool. The radius of the pool will be 7 feet. She will put a cover on the pool and build a fence around the pool. How much material will she need to cover the top of the pool?
Answer:
about 154 square feet
Step-by-step explanation:
The area of the pool is given by the formula for the area of a circle:
A = πr²
A = π(7 ft)² = 49π ft² ≈ 153.94 ft²
About 154 square feet of material will be needed to cover the top of the pool.
__
Additional comment
The circumference of the pool is 2πr, or 14π feet -- about 44 feet.
