A person uses about 315 calories to jog 3 miles. How many calories will be used in a 10 mile jog?
Step-by-step explanation:
315 calories for 3 miles.
315/3 = 105 calories for 1 mile
105×10 = 1050 calories for 10 miles
Answer:
Hello! The answer is 1050 calories.
Step-by-step explanation:
To calculate this, you have to find how many calories are used PER mile. To do this, you have to divide the total calories by the mileage:
315 ÷ 3 = 105
Now that you have the calories used per mile, you can find how many calories are used in a 10 mile jog:
105 × 10 = 1050 calories
20. Sofia paid $11.80 for a pen, a marker, and a binder. The marker cost $0.80 more than the pen. The binder cost 4 times as much as the marker. What was the cost of the pen?
Answer:
$1.30
Step-by-step explanation:
Let x = the cost of the pencil
Let x + .80 = the cost of the pen
Let 4(x + .80) = the cost of the binder
x + x + .80 + 4(x + .80) = 11.80
2x + .80 + 4x + 3.20 = 11.80
6x + 4.00 = 11.80
6x = 7.80
x = $1.30
x + .80 = $2.10
4(x + .80) = $8.40

IM CONFUSED: A used car dealer has the following information for 2 months of sales:
Month 1: 239 cars sold
Month 2: 324 cars sold
Do we have an increase or a decrease in sales and what percentage?
Answer:
Rounds to about 135% increase.
Step-by-step explanation:
Increase/original number x 100
324 / 239 × 100. This rounds to about a 135% increase.
I'm not sure about the answer, just saying. So you might want to double-check the formula for percent change. Thank You.
To determine if there's an increase or a decrease in sales and the percentage change, we need to compare the number of cars sold in Month 2 with the number sold in Month 1.
Calculate the difference in sales:
Difference = Month 2 sales - Month 1 sales
Difference = 324 cars - 239 cars
Difference = 85 cars
To find the percentage change, use the following formula:
Percentage Change = (Difference / Initial Value) * 100
In this case, the initial value is the number of cars sold in Month 1 (239 cars).
Percentage Change = (85 cars / 239 cars) * 100
Percentage Change ≈ 35.56%

7.23. A freight train travels 1 mile in 1 minute 30 seconds. At this rate, how many miles will the train travel in 1 hour?
Answer:
40 miles in 60 minutes
Step-by-step explanation:
1 hour has 60 minutes, and since the freight train travels 1 mile in 1.5 minutes, it can be said that the train travels 2 miles in 3 minutes (assuming a constant rate). This becomes a problem of equal ratios:
[tex]\frac{2}{3}=\frac{x}{60}[/tex] , where the numerator refers to distance, and the denominator refers to the time
After cross multiplication, we find that 3x = 120, or x = 40.
Therefore, it takes 1 hour for the train to travel 40 miles
Answer:
The number of miles will the train travel in 1 hour is 40 miles.
Step-by-step explanation:
Given:
A freight train travels 1 mile in 1 minute 30 seconds.
Find:
The number of miles that the train will travel in 1 hour
Step 1 of 1
One minute 30 seconds is [tex]$\frac{3}{2}$[/tex] minutes, so the train's speed is
[tex]$$\begin{aligned}\text { spced } &=\frac{1 \text { miles }}{\frac{3}{2} \text { minutes }} \\&=\frac{2}{3} \frac{\text { miles }}{\text { minute }}\end{aligned}$$[/tex]
There are 60 minutes in an hour, so the distance traveled in 60 minutes is distance [tex]=(60$ minutes $) \cdot\left(\frac{2}{3} \frac{\text { miles }}{\text { minute }}\right)$[/tex]

7.33. Tom can paint Mr. Thatcher's fence in 6 hours, while Huck can paint Mr. Thatcher's fence in 5 hours. If they work together, then how long will it take them to paint the fence?
Answer:
It takes them 30/11 hours to paint them together.
Step-by-step explanation:
This is known as a work problem (rate * time = work). We are given the individual times for Tom and Huck (6 hours and 5 hours respectively). However, we are not given the rates at which they can paint the fence. Since we know that the total work that they both do individually is 1 (there is 1 job to do), we can calculate the rates at which Tom and Huck paint the fence on their own:
[tex]Tom: R_{T}*6=1\\Huck: R_{H}*5=1[/tex]
We can isolate R{t} and R{h} to find the rates at which Tom and Huck work:
[tex]Tom: R_{T}=\frac{1}{6}\\Huck: R_{H}=\frac{1}{5}[/tex]
Now, we can calculate the time it takes for Tom and Huck to work together using the same formula (the combined rate is just the sum of Tom and Huck's individual rates):
[tex](\frac{1}{6} +\frac{1}{5})*T=1\\\\T*(11/30)=1 , T = 30/11[/tex]
Therefore, the time it takes them to paint the fence together is 30/11 Hours
Answer:
The number of hours it will take them to paint the fence is 2.7 hours.
Step-by-step explanation:
Given:
Tom can paint Mr. Thatcher's fence in 6 hours, while Huck can paint Mr. Thatcher's fence in 5 hours.
Find:
the number of hours it will take them to paint the fence
Step 1 of 1
Determine their work rates, and then add them.
In particular, Tom can paint [tex]$\frac{1}{6}$[/tex] of a fence per hour, and Huck can paint [tex]$\frac{1}{5}$[/tex] of a fence per hour.
So, together they can paint [tex]$\frac{1}{6}+\frac{1}{5}=\frac{11}{30}$[/tex] of a fence per hour. Therefore, the time to paint the whole fence is [tex]$\frac{1 \text { fence }}{\frac{11}{30} \text { fences per hour }}=\frac{30}{11}$[/tex] hours
[tex]$=2 \frac{8}{11} \text { hours, }$$[/tex] or a little over 2.7 hours.

Answer:
y=60° b=60°
Step-by-step explanation:
the sum of all degrees of interior triangle is 180
in the first one, 30° and 90° have been given.(that small square represent 90°)
so 180°-90°-30°=60°
in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°
Let's take this problem step-by-step:
Both problems involve triangles:
⇒ let's find out the sum of the interior angle w/ formula 180(n-2)
Total Interior Angle Sum of Triangle = 180(3-2) = 180
Let's solve the first problem (A)
⇒ we know the total interior angle sum is 180 degrees
⇒ we know that two of the angles are 30 degrees and 90 degrees
* any angle with a square on them is 90 degrees
⇒ therefore:
30 + 90 + y = 180
120 + y= 180
y = 60
Let's solve the second problem:
⇒ the angle opposite the exterior angle, 120 degrees, is on a flat line
with it
⇒ therefore it is 60 degrees
⇒ two angles on a flat line equal 180 degrees
⇒ two angles are therefore 60 degrees
⇒ therefore:
60 + 60 + y = 180
120 + y = 180
y = 60
Answer:
(A) y= 60(B) y =609. You want to compare the average amounts of time students in sixth, seventh, and eighth grade spend on homework each week.

Josh is 72 inches tall. Ruben is 9/10 as tall as josh. John is 11/12 tall as ruben. a. what is rubens height in inches b. what fractional of of joshs height is johns?
Answer:
A. Ruben's height- 64.8 inches
B. John's height- 3/4 of Josh's height
Step-by-step explanation:
A. Since Ruben's height is 9/10ths of Josh's, and Josh's is 72 inches, we can find 90% of Josh's height which is 72, therefore giving us 64.8 inches.
B. Now take John's height of being 11/12th as being tall as Ruben, we can enter 11/12th of 64.8 which would give us about 54 inches. Finally, taking John's height of 54 inches, we would divide it with Josh's height of 72 inches. Hence, 54/72=3/4 as a fraction.

1. Vertical Line Test: By definition a function can only output 1 value for each unique input. So if I were to put a vertical line on a graph it should only intersect one point, if it intersects two, that would mean there is 2 outputs for 1 input, so it's not a function
2: Term
3: Sequence: I don't really know how to explain this besides it's literally the definition
4: Relation: This can also be a function, but it it doesn't pass the vertical line test, it's just a relation
5: Solution: A solution to an equation is just what value makes an equation true (both sides equal)
6: Variable: The value varies, it can be anything, depending on what the equation is, so for example y=mx+b, the value of y varies depending on the value of x (and also m and b obviously, but those are constants)
