One equation that represents this statement above me could be: <span>4r + 3 (10-r) = 37.
</span>How? R = Rollercoaster - B = Boat Rides
r + b = 10
37 tickets were spent so..
4*r + 3*b = 37
We just multiplied the number of rides on roller coasters and the boats with the price of both.
Now we have to express boat rides from the first equation:
b = 10-r, and express that in the second equation, now we get:
4r + 3(10-r) = 37, which is the answer.
Remark
<em><u>Two remarks</u></em>.
1. The weight of the ostrich is on the numerator of the ratio.
2. You have to change units of one of them to make the units the same.
Step One
Change the 150 kg to grams
150 kg * 1000 gram/1 kg = 150,000 grams
Step Two
Find the % of ostrich to hummingbird
Percent = (150,000 / 2) * 100%
Percent = 75000 * 100% = 7 500 000% larger.
Answer:
5
Step-by-step explanation:
you need to use the Pythagorean theorem
a^2+b^2=c^2
a&b=sides
c=hypotonuse
plug the side values into the equation
4^2+3^2=c^2
16+9=c^2
25=c^2
you have to square root 25 to find c itself
c=5
53 is kilogram53 is kilogram but I’m not to sure what 58 is
