Step-by-step explanation:
PRIMERO SE CALCULA LE VELOCIDAD CON EL VIENTO QUIETO
v = [tex]\frac{320 mi}{3 h}[/tex] = 106.6 mi/h
DESPUÉS SE ENCUENTRA LA VELOCIDAD DEL AVIÓN EN CONTRA DEL
VIENTO
v = [tex]\frac{320 mi}{4 h}[/tex] = 80 mi/h
FINALMENTE SE ENCUENTRA LA VELOCIDAD DEL VIENTO
v = 106.6 mi/g - 80 mi/h = 26.6 mi/h

48 girls, 41 boys, and 5 teachers sat in the gym. Write the ratio of girls to boys in three ways.
A: 48 to 41, 41:5, 5/48
B: 41 to 48, 41:48, 41/48
C: 48 to 41, 48:41, 41/48
D: 48 to 41, 48:41, 48/41
Answer:
D
Step-by-step explanation:
The answer is D because the question is asking for girls to boys. So anything that has 5 in it is wrong because it isn't asking for teachers, which eliminates A. So since it is asking girls to boys the number order has to be 48 then 41 because it is asking for girls first then to boys. So that makes B wrong. When it comes to the fraction part of the ratio the first number it is asking for (which is girls) always goes on top. So that eliminates C which leaves only answer to be D.

D

Sally is making 15 individual blueberry cheesecakes. How many pounds of blueberries will be in each cheesecake it 5 and 1/4 pounds of blueberries
Answer:
.35lbs or 7/20lbs
Step-by-step explanation:
if 5 1/4 lbs of blueberries are being distributed evenly through 15 cheesecakes, you would divide 5 1/4 by 15 to see how many lbs of blueberries would be in each cheesecake, which would make .35 lbs of blueberries per cheesecake, or 7/20 lbs.
The number of pounds of blueberries will be in each cheesecake should be .35lbs or 7by 20lbs
The calculation is as follows;
When 5 1 by 4 lbs of blueberries are being distributed evenly through 15 cheesecakes,
So, here we have to divide 5 1 by 4 by 15 i.e.
[tex]= 5\frac{1}{4} \div 15[/tex]
= 0.35 lbs

A snail can crawl at a rate of 6 cm in 0.75 minutes. Which represents the constant rate of change of the snail's crawl?
Answer:
0.00133m/sStep-by-step explanation:
Given
distance crawled by the snail = 6cm = 0.06m
Time taken = 0.75minutes = 0.75*60
Time taken = 45secs
Required
constant rate of change of the snail's crawl (speed)
Speed of the snail = distance/time;
Speed of the snail = 0.06/45
Speed of the snail = 0.00133m/s
Hence the constant rate of change of the snail's crawl in m/s is 0.00133m/s
