Answer:
The correct answer is 2 23/63
Step-by-step explanation:
To determine how much the plant grew, start by subtracting the starting whole number value from the ending whole number value.
4 - 1 = 3
Now do the same with the fractions. Use common denominators.
2/9 - 6/7
14/63 - 54/63
-40/63
Now add the two numbers together.
3 - 40/63 = 2 23/63
Answer:
Scaling is used to resize the dimension of a structure to fit the different platforms, like from structure to paper.
Step-by-step explanation:
To resize down-scale the dimension of a room, if the scale is 1/4 inches per foot, then the size of a 6x4 feet (width and length) room would be;
1/4 x 6 = 1.5 inches
1/4 x 4 = 1 inches
that is, 1.5 x 1 inch on paper when scaled down.
First car: $10 + 3 every mile
Second car: $20 + 2 per every mile
For the part that says "Write an equation that represents the cost of
each car service and determine when they cost the same.", find the LCM of 13 and 22.
Answer:
is it y = -15x + 63
Step-by-step explanation:
The cars speed in kilometres per hour is = 87.2 Km/hr
<h3>Calculation of speed of a car:</h3>
The speed of the car = d/t
The distance(d) travelled by the car = 41 kilometers
The time(t) taken to cover the distance = 28 minutes
To solve, convert minutes to hours
But 60 mins = 1 hour
28mims = X
cross multiply,
X = 28/60
X = 0.47hour
To calculate the speed substitute d and t with it's variables provided.
speed = 41/0.47
=87.2 Km/hr ( which is to the nearest tenth)
Therefore, The cars speed in kilometres per hour is = 87.2 Km/hr
