Answer:
D.
d = 3t; 90 mi
Step-by-step explanation:
Bicycling A bicyclist traveled at a constant speed during a timed practice period. Write a proportion to find the distance the cyclist traveled in 30 min.
elapsed time distance
10 min 3 mi
25 min 7.5 mi
Graph it. :)
Start at (0,0), then at 10 min. on the x-axis, go 3 spaces up on the y-axis and plot a point. Do the same for 25 min. and 7.5 miles. Draw a line through all of those points, and see where the line hits on the y-axis when the x-axis is at 30 min. :)
If two things vary directly it means their ratio is a constant. Therefore from the formula rt=d. r=d/t, r=3/10 or 7.5/25 which reduces to 3/10. This is the constant speed,the lable is mi/min. Now use (d/30)=(3/10) and solve for d. Cross multiply and 10d=90, or d=9 mi
Using the information given, the distance formular = 0.3t ; distance covered in 30 minutes = 9 miles
Since the speed is constant :
We could use either of distance and elapsed time values to create an equation :
Elaspsed time - - - - Distance
10 minutes _____ 3 miles
Recall :
Distance covered = speed × time
Distance covered = speed × time Speed = distance / time
Speed of bicyclist is thus :
(3 miles / 10 minutes) = speed
Speed = 0.3 miles per minute
Hence,
Distance = 0.3 × time
For a travel time of 30 minutes ;
Distance covered = 0.3 × 30 = 9 miles
Hence, distance formular = 0.3t ; distance covered in 30 minutes = 9 miles

Answer:
Y=25x
Step-by-step explanation:
Cross multiply
75/3=25
50/2=25
25/1=25
Ans: 25
Answer:
y= 25x.
Step-by-step explanation:
This is direct variation because y/x = 25/1 = 50/2 = 75/3 = 25 , and when x = 0 y = 0.
So the equation is y = 25x.

solve using suitable property -2/3 x 5/7 x -9/16 x 14/25
Answer:
[tex]\dfrac{3}{20}[/tex]
Step-by-step explanation:
We need to solve the given expression i.e.
[tex]\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-9}{16}\times \dfrac{14}{25}[/tex]
It can be calculated by simplifying such that,
25 = 5 × 5
16 = 8 × 2
14 = 7× 2
9 = 3 × 3
If we use all the values,
we get,
[tex]\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-9}{16}\times \dfrac{14}{25}=\dfrac{3}{20}[/tex]
So, the value of the above expression is equal to [tex]\dfrac{3}{20}[/tex].

Ricardo made a data table with 4 rows and 10columns
Total number of cells is
= 4×10
= 40
He colors 3/8 of the cells yellow
Therefore the number of cells in yellow can be calculated as follows
= 3/8 × 40
= 15
Hence 15 cells were painted yellow

Looking at the triangle we see the angles:
58, x
We also see a right angle, therefore you now have:
90, 58, 0
All three angles of a triangle should have a total of 180 degrees, so we add the known angles and subtract the total from 180.
90 + 58 = 148
180 - 148 = 32
Therefore, x = 32 or C

A person invested \$150$150 in an account growing at a rate allowing the money to double every 13 years. How much money would be in the account after 22 years, to the nearest dollar?
Answer:
Amount after 22 year = $484.80 (Approx.)
Step-by-step explanation:
Given:
Amount deposit in bank = $150
Double in year = 13 year
Find:
Amount after 22 year
Computation:
A = P[1+r]ⁿ
Amount after 13 year = 2 x 150
Amount after 13 year = $300
300 = 150[1+r]¹³
2 = [1+r]¹³
Rate of interest = 5.477%
Amount after 22 year
A = P[1+r]ⁿ
Amount after 22 year = 150[1+5.477%]²²
Amount after 22 year = $484.80 (Approx.)
