It takes them 1 7/8 hrs to complete the job together.

How:
Fred = 3 hrs
Jason = 5 hrs

1/3x + 1/5x = 1/x

3x x 5x = 15 —> 3x/15 + 5x/15 = 15/15

3x + 5x = 8x —> 8x/15 = 1.875 = 1 7/8 hrs

During one waiters shift he delivered 13 appetizers, 17 entrées, and 10 desserts what percentage of the dishes he delivered were

Triss [41]

Question

During one waiters shift he delivered 13 appetizers, 17 entrées, and 10 desserts what percentage of the dishes he delivered were: A. Desserts B. Appetizers C. entrees

Answer:

A)Desserts = 25 %

B)Appetizers = 32.5 %

C)Entrées = 32.5 %

Step-by-step explanation:

Given:

Number of appetisers = 13

Number of entrees = 17

Number of desserts = 10

A. percentage of the dishes he delivered were Desserts

Percentage of Desserts = $\frac{\text{ Number of dessert}}{\text{ total number of dishes}} \times 100$

Total number of dishes = 13 + 17 + 10 = 40

Percentage of Desserts = $\frac{10}{40} \times 100$

Percentage of Desserts = $0.25 \times 100$

Percentage of Desserts = 25 %

B. percentage of the dishes he delivered were Appetizers 

Percentage of Desserts = $\frac{\text{ Number of Appetizers }}{\text{ total number of dishes}} \times 100$

Percentage of Desserts = $\frac{13}{40} \times 100$

Percentage of Desserts = $0.325 \times 100$

Percentage of Desserts = 32.5 %

C. percentage of the dishes he delivered were Entrées 

Percentage of Desserts = $\frac{\text{ Number of Entrees }}{\text{ total number of dishes}} \times 100$

Percentage of Desserts = $\frac{17}{40} \times 100$

Percentage of Desserts = $0.425 \times 100$

Percentage of Desserts = 42.5 %

Answer: B.20

Step 1: Understand the graph

In the graph provided, each line goes up by 10 on the y-axis, with the graph marking each 50. On the x-axis, every 5 lines is equal to 1, as indicated on the graph.

Step 2: Find the unit rate

To find the unit rate, we need to find where the line hits 1 on the x-axis. To do so, go to one on the x-axis, and go up until you find where the line hits. Then we see the value on the y-axis to know the unit rate. In this case, it is on the second line above. Since we established in step 1 that each line is equal to 10 on the y-axis, we know that the two lines will be equal to 20.

This is your answer! The unit rate is 20. Hope this helps! Comment below for more questions.

5x+y=4x-y=2GRAPHINGI need The Two slopes and The Two y- intercepts pleaseeeee

weqwewe [10]

Given the equations:

5x + y = 4

x - y = 2

Convert the standard from to the slope intercept from

The slope intercept form is : y = mx + c

Where m is the slope and c is y-intercept

So, for the equation 5x + y = 4

the slope intercept form will be:

$y=-5x+4$

so, the slope = m = -5

and y-intercept = c = 4

The graph of the line will be as following:

For the second equation: x - y = 2

The slope intercept form is :

$y=x-2$

The slope of the line = 1

and the y-intercept = -2

The graph of the line will be as following :
