The chart below shows how many cups of lemonade Marcia sold each hour she had her lemonade stand set up. To make 10 cups of lemonade, Marcia has to squeeze 3 lemons. How many lemons did Marcia use in the first 4 hours?
Answers
Answer:
[tex]123\frac{1}{3}\ cups[/tex]
Step-by-step explanation:
Given
[tex]10\ cups = 3\ lemons[/tex]
See attachment for chart
Required:
Lemons used in first 4 hours
First, we calculate the number of lemon sold in the first 4 hours.
[tex]Lemon = 6 + 5 + 11 + 15[/tex]
[tex]Lemon= 37[/tex]
Represent the number of cups of lemonades needed with x
So, we have:
[tex]x = 37\ lemons[/tex]
and
[tex]10\ cups = 3\ lemons[/tex]
Cross Multiply:
[tex]x * 3 = 10 * 37[/tex]
[tex]3x = 370[/tex]
Make x the subject
[tex]\frac{3x}{3} = \frac{370}{3}[/tex]
[tex]x = \frac{370}{3}[/tex]
[tex]x = 123\frac{1}{3}[/tex] cups

A car covers a distance of 60 km in 3 hours. However, for the first 40 km it travels 16 km/hr. At what speed must it travel for the rest of the distance in order to complete the journey on time?
Answers
Answer:
40 km/hr
Step-by-step explanation:
Given that:
Total distance covered in 3 hours = 60km
Speed during first 40 km = 16km/hr
Hence, time spent during the first 40 km ;
Recall:
Time = distance / speed
Time = 40 / 16
Time = 2.5 hours
Hence, speed required to cover the remaining (60 - 40) = 20km in (3 - 2.5) hours =0.5 hours
Speed = distance / time
Speed = 20 / 0. 5
Speed = 40 km / hr

The expression represents the number of comic books a friend has is F = 3c + 5.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
As per the given,
A friend has 5 more than triple c
Suppose a friend has an "F" number of comic books then,
F = 3c + 5
Hence "F = 3c + 5 is an expression that indicates how many comic books a friend owns".

Answers
Answer:
y = 1x + 2
Step-by-step explanation:
To fill in slope intercept form(y = mx + b) identify the initial value(b) and slope(m).
The initial value is the y coordinate when the x coordinate is 0. It is also known as the point where the line crosses the y axis. This point on the graph is (0, 2). So, the initial value is 2.
Slope is identified by finding a point on the graph that the line passes through and creating a right triangle to a point that is even with both point. Then, divide the y coordinate of that point by its x coordinate. One coordinate you could use is point (-2, 2). 2 divided by -2 is -1. But, since the line has a positive association, the slope is going to be a positive number. So, the slope is 1.
Now fill in the the slope intercept form.
y = mx + b ---> y = 1x + 2
Answer:
y= X + 2

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the length of the mat is 5 ( 1 / 4 ) and the length cut by 2 / 3 feet. The new length will be calculated as below:-
New length = 5 ( 1 / 4 ) - ( 2 / 3 )
New length = ( 21 / 4 ) - ( 2 / 3 )
New length = ( 63 - 8 ) / 12
New length = ( 55 ) / 12
New length = 4 ( 7 / 12 )
Therefore, the new length of the mat will be 4 ( 7 / 12). The correct option is A.
