Answer:360 m/s
Step-by-step explanation:
The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
As we can see in the graph:
When the air temperature is 10°C the speed of sound is around 337m/s
When the air temperature is 20°C the speed of sound is around 344m/s
When the air temperature is 30°C the speed of sound is around 348m/s
When the air temperature is 40°C the speed of sound is around 355m/s
From the above observation, the air temperature increases the speed of the sound increases.
So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.
Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.

Solve the equations:
1. 9x - 5 = 5x + 7
2. 8x - 2 = x - 16
3. 8x + 5 = 2x + 23
4. 2x + 8 = 5x + 20
5. 5(2x + 6) = 3x - 5
Answer:
5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x
step1:- 5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x
step2:- 5x + 3x - 9x - 20 = 8x - 2x + 6 - 5
-x - 20 = 6x + 1
stp 3
-20 = 7x + 1
step 4
-21 = 7x
divide both sides by 7:-
-3 = x
thats the solution x = -3
Answer:
1. X=3, 2. X= -2, 3. X=3, 4. X= -4

Jimmy takes 12 minutes to run 6 times around a 600 meter track. Assuming he runs at a constant speed, how long does he take to run 1 kilometer?
Answer:
10/3 minutes
Step-by-step explanation:
12 minutes to run 6 times is the same as 2 minutes to run once (ratios)
so it takes 2 minutes to run once around a 600 m track
so 2 minutes/600m = x minutes/1000m
x = 2/600 * 1000 = 20/6 = 10/3
Answer:
10/3
Step-by-step explanation:
At Breakfast Break, 2 eggs and 1 sausage patty cost $2.23 and 3 eggs with 2 sausage patties cost $3.76. Assuming that these amounts only pay for the eggs and sausage, how much does one sausage patty cost?
Cost of one sausage patty is $0.83.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
Cost of 2 eggs and 1 sausage patty = $2.23,
Cost of 3 eggs and 2 sausage patties = $3.76.
Write above expression in equation form,
2 eggs + 1 patty = 2.23 (1)
3 eggs + 2 patties = 3.76 (2)
To find the cost of patty, multiply equation (1) with 3 and equation (2) with 2,
6 eggs + 3 patties = 6.69 (3)
6 eggs + 4 patties = 7.52 (4)
By solving equation (3) and (4)
1 patty = 0.83
The cost of 1 sausage patty is $0.83.

The distance between two cities on a map is 4 1/2 inches. The actual distance between the two cities is 24 miles.
What is the scale used on the map?
If the scale on a different map of the same area is 1/4 inch = 1 mile, how many inches separate the same two cities?
Helper
Jan 13, 2020
the scale is 4.5in/24mi
since 1 mile = 63360 in, that means the scale is
4.5 : 24*63360 = 4.5 : 1520640 = 1:337920
Maybe now you can figure the scale on the 2nd map.

huh. I guess you can't follow the logic? If 1/4 inch = 1 mile then the scale is
1/4 in : 63360 inin = 1/4 : 63360
now just simplify that so it is 1 : ____
