Answer:
The city and highway average are about the same
Step-by-step explanation:
The m/slope of this graph tells us the relation between fuel used and miles traveled.
So, by looking at the slope, we can tell the average miles per liter for driving.
Because the slope of this graph stays fairly consistent (the slope stays the same throughout the entire graph, and there is no sudden change in the miles per liter ratio), we know that the fuel usage does not change.
So, we don't even have to calculate the slope for each separate section, we know that the usage is about the same (from simply looking at the graph).
(Also, if you specifically wanted to calculate slope to confirm, like I just did, you could do this too. Without even having to calculate the slope itself, you can find one point in each section to judge. The points I used were (2, 10) [10m traveled with 2 liters, meaning 5m traveled with 1 liter] and (10, 50) [50m traveled with 10 liters, 5m traveled with 1 liter])
Answer:
EF² = FA²+ EA²
20² = 12² + FA²
400 -144 = FA²
256 =FA²
16cm = FA
Now in Δ DAG
DG² = AG² + DA²
13² = 12 ²+ DA²
169 -144 = DA²
25 = DA²
5cm = DA
Then that means diagonal DF = DA + FA
= 5 + 16
= 21cm

Answer:
A)66 B)27.273%
Step-by-step explanation:
Given
Number of pizzas sold yesterday ,m=55
20% increase in pizzas sold from yesterday will get the employee a bonus
So number of pizzas to be sold today for the employee to get a promotion
Therefore 66 pizzas need to be sold today for the employee to get a bonus
if the number of pizzas sold today, n=40
⇒ Change= n-m= 40-55= -15
Negative sign indicates decrease in pizzas sold
Percentage change
=27.273%
Answer:
x = 16
Step-by-step explanation:
Given:
- Number of students = 6
- Average mark = 15
Therefore, total marks = 15 × 6 = 90
To find the value of x, add up the individual marks:
12 + 16 + 14 + 13 + 19 + x = 74 + x
Now equate this to the total number of marks found previously:
74 + x = 90
Solve for x:
⇒ 74 + x - 74 = 90 - 74
⇒ x = 16
Therefore, the value of x is 16.
