No because if you multiply the ratio 7:4 by 7 you would get 49:28
Answer:
$13
Step-by-step explanation:
Given that :
Increase in salary factor = 11/10
New salary = $14.30
Initial salary = x
To obtain the value of the initial salary,
The product of the scale factor by the initial salary sgiuf give the amoi tof the new salary
11 / 10 * x = 14.30
1.1x = 14.30
x = 14.30 / 1.1
x = $13
Hence.initial salary per hour = $13
The tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.
<h3>What is an arithmetic operation?</h3>
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a chess tournament starts at 12:30 p.m. and ends at 5:00 p.m.
The difference between 12:30 p.m. and 5:00 p.m. can be calculated after changing time into 24 hours clock
12:30 p.m. = 12 hours 30 minutes = 12.50
5: 00 p.m. = 17 hours 00 minutes = 17.00
Difference between them:
= 17.00 - 12.50
= 4.5 hours
4.5 < 5
Thus, the tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.

Answer:
16 miles
Step-by-step explanation:
The height is 26 miles. Multiply that by 2 which gets 52 and then subtract that from 84. That gives you 32 which means the sum of the lengths is 32/2 which is 16 miles
Answer:
Distance between two cities that are 9 inches apart on the map is 11.97 miles (12 miles)
Step-by-step explanation:
As it is given in the question scaled distance on a map is 3 inches = 4 miles.
Now we have to calculate how many miles in 1 inches on the map = 4÷3
= 1.33miles
Now we get the value of 1 inches on the map = 1.33 miles
9 inches = 1.33 × 9 = 11.97 miles ( Probably close to 12 miles if allowing for changing elevations in the distance)
In elementary school we used to refer to this as a ratio problem; two equal ratios with one containing unknown as :
X/C = A/B
X miles / 9 inches = 4 miles / 3 inches
X = 9 (4÷3)
X = 9×1.33
X = 11.97
=12 miles
