Answer:
d=120t
Step-by-step explanation:
i dont have an explanation for this i just got it wrong and im giving you the answer hope this helps also you have to put it in exactly like this
d = 120t
^^^^^^^^
The function that relates the distance traveled d to the time t is (d = 120t) and this can be determined by using the formula of speed.
Given :
A train leaves the station at time t0. Traveling at a constant speed, the train travels 360 kilometers in 3 hours.The following steps can be used in order to determine the function that relates the distance traveled d to the time t:
Step 1 - The formula of speed can be used in order to determine the function that relates the distance traveled d to the time t.
Step 2 - The speed formula is given below:
[tex]\rm s = \dfrac{d}{t}[/tex]
where distance is 'd' and time is 't'.
Step 3 - Now, substitute the values of d = 360 and t = 3 in the above formula.
[tex]\rm s = \dfrac{360}{3}[/tex]
s = 120 km/hr
Step 4 - Now, at time 't' the distance is given by:
[tex]120=\dfrac{d}{t}[/tex]
d = 120t

For a scale to pass inspection, the scale's reading can vary by at most
0.1% from the actual mass of an object on the scale. A test mass has
an exact mass of 250.00 grams. In what range must the scale's reading
be for the scale to pass inspection?
Answer:
I think its 249.99 to 250.01
Step-by-step explanation:
The range of the variation for the scale will be 249.75 grams to 250.25 grams.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that for a scale to pass inspection, the scale's reading can vary by at most 0.1% from the actual mass of an object on the scale. A test mass has an exact mass of 250.00 grams.
The variation of the mass will be calculated as:-
Variation = 250 x 0.1% = ( 250 x 0.1 ) / 100 = 0.25
Higher variation = 250 + 0.25 = 250.25 grams
Lower variation = 250 - 0.25 = 249.75 grams
Therefore, the range of the variation for the scale will be 249.75 grams to 250.25 grams.

b = [tex]\frac{7}{5}[/tex] = 1.4
Step-by-step explanation:

Melinda earns $48 for every 3 lawns she mows in her neighborhood. She wants to buy a skateboard that costs $208. How many lawns will Melinda have to mow to be able to buy the skateboard?
Enter the correct answer in the box.
Answer:
13 lawns
Step-by-step explanation:
Find out how much money Melinda earns for 1 lawn mowed (variable x represents money earned):
3x = 48
Isolate the variable by dividing both sides by 3
3x ÷ 3 = 48 ÷ 3
1x = 16
x = 16
She earns $16 per mowed lawn
Set up equation to find out how many lawns she needs to mow to earn $208 (variable y represents lawns mowed):
16y = 208
Isolate the variable by dividing both sides by 16
16y ÷ 16 = 208 ÷ 16
1y = 13
y = 13
She needs to mow 13 lawns to earn $208
Answer: The answer is 13 lawns... Have a great day!

A meat distributor paid $2.75 per pound for hamburger and $4.50 per pound for ground sirloin. How many pounds of each did he use to make 75 pounds of meat mixture that will cost $3.24 per pound?
Answer:
The number of pounds of hamburger meat = x = 54 pounds.
The number of pounds of ground sirloin = y = 21 pounds
Step-by-step explanation:
Let the number of pounds of hamburger meat = x
the number of pounds of ground sirloin = y
How many pounds of each did he use to make 75 pounds of meat mixture that will cost $3.24 per pound?
x + y = 75...... Equation 1
x = 75 - y
A meat distributor paid $2.75 per pound for hamburger and $4.50 per pound for ground sirloin.
$2.75 × x + $4.50 × y = 75 × $3.24
2.75x + 4.50y = 243
We substitute 75 - y for x
Hence,
2.75(75 - y) + 4.5y = 243
206.25 - 2.75y + 4.5 y = 243
Collect like terms
- 2.75y + 4.5 y = 243 - 206.25
1.75y = 36.75
y = 36.75/1.75
y = 21 pounds
Note
x = 75 - y
x = 75 - 21
x = 54 pounds
Therefore:
The number of pounds of hamburger meat = x = 54 pounds.
The number of pounds of ground sirloin = y = 21 pounds
