The super speedway at Daytona International Speedway is 2.5 miles long. The road course there is 1.4 times as long as the super speedway. How long is the road course?
Answer:
3.5 miles
Step-by-step explanation:
From the question, we have the following information:
The super speedway at Daytona International Speedway is = 2.5 miles
long
The road course there is = 1.4 times as long as the super speedway.
How long is the road course?
The length of the road course is calculated as:
1.4 × length of the super speedway
1.4 × 2.5 miles
=>3.5 miles
Therefore, length of the road course I s 3.5 miles.

Find a fraction in between 21/34 and 34/55
Answer:
A fraction between that is 2311/3740
Step-by-step explanation:
This is because the denominator is simplified into one number and the fraction is taken from there.
2311/3740
Step-by-step explanation:34 = 2×17
55 = 5×11
LCM = 2×5×11×17 = 1870
⁵⁵⁾21/34 = ²⁾1155/1870 = 2310/3740
³⁴⁾34/55 = ²⁾1156/1870 = 2312/3740
2310/3740 < 2311/3740 < 2312/3740

Help asap!!! I really need help on this
Step-by-step explanation:
The function is positive when the graph is over the x-axis, and negative when the graph is under the x-axis.
As we can see from the graph, it has x-intercepts at x = -3 and x = 3.
Since the graph curves upwards, the function is positive in intervals (-∞, -3) U (3, ∞) and negative in the interval (-3, 3).

2(4s-16)-5s= -5 What is S?
Answer:
s=9
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*(4*s-16)-5*s-(-5)=0
Pull out like factors :
4s - 16 = 4 • (s - 4)
Pull out like factors :
3s - 27 = 3 • (s - 9)
3 • (s - 9) = 0
Solve : s-9 = 0
Add 9 to both sides of the equation :
s = 9

Need 13&14!! ASAP, will put Brainliest
Answer:
13- A 14-B
Step-by-step explanation:
You take the formula (x1+x2/2, y1+y2/2) and plug in accordingly. For instance, when you plug the values in for 13, you would get:
x1+-9/2, y1+7/2= -8,2
All you have to do from there is a simple guess and check or plug in each number from the multiple answer choices you have. You should then get A (-7,-3) Do the same with 14, in which you should get B (11,-20)

Mary drove 4 hours to reach her camping spot. She increased her speed by 15 miles per hour reducing her travel time by one hour. How fast did she drive going to the camping spot?
Answer:
45 miles per hour
Step-by-step explanation:
Mary drove 4 hours to reach her camping spot. Driving home, she increased her speed by 15 miles per hour, reducing her travel time by 1 hour. How fast did she drive going to the camping spot?
d = rt
Where,
d = distance
r = rate of speed
t = time
Going to the camping spot
d=rt
Where, t = 4 hours
d = r × 4
d = 4r (1)
Driving home
She reduced her travel time by 1 hour
That is t = 4 -1 = 3 hours
Then increased speed by 15 miles per hour
That is r = r + 15
d=rt
d = (r+15) × 3
d = 3r + 45 (2)
Equating the two equations
4r = 3r + 45
Collecting like terms
4r - 3r = 45
r = 45
r = 45 miles per hour
check:
d = 4r
d = 45*4
=180 miles
d = 3r + 45
d = 3*45 + 45
= 135 + 45
=180 miles

Solve the equation-3y = 21 using inverse operations. What is the inverse operation step? What is the solution?
Answer:
Y=-7
Step-by-step explanation:
The solution to the equation -3y = 21 is y = -7.
To solve the equation -3y = 21 using inverse operations, we want to isolate the variable y by performing the inverse operation.
Now, the inverse operation of multiplication by -3 is division by -3.
By dividing both sides of the equation by -3, we can isolate y.
Let's perform the inverse operation:
(-3y) / -3 = 21 / -3
y = -7
Therefore, the solution to the equation -3y = 21 is y = -7.

Hana made $126 for 7 hours of work.
At the same rate, how many hours would she have to work to make 216?
Answer:
12 hours
Step-by-step explanation:
126 dollars / 7 hours of work = 18 dollars per hour (Pretty neat honestly)
So she made 216 dollars / x = 18 dollars per hour
18x=216 (cross multiply)
216/18 = 12 hours of work
Answer: 12 hours
Step-by-step explanation:
It takes her 7 hours to make $126 dollars and we need to find out how many hours(a) to make $216
So this is the equation
7 hours= 126 dollars
a hours= 216 dollars
Cross multiply
126 x a = 7 x 216
126a = 1512
Divide both sides by 126
a= 12 hours

Which of the following is a proportion? 9/12= 8/10 3/4= 9/12 6/8= 8/12 12/18= 9/16
Answer:
It would be 3/4=9/12
Step-by-step explanation:
The proportion relationship of the given ratios is 3/4= 9/12 thus option (B) is correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
In the fractions, 3/4

If f(x)=x+1, find f(x+10).
Answer:
x + 11
Step-by-step explanation:
Substitution!
Since you're trying to find f(x+10), you would replace each x in the equation (in this case only one) with x+10.
So instead of
[tex]x+1[/tex]
it would be
[tex](x+10)+1 = x + 10 + 1 = x + 11[/tex]

Solve the inequality 6x – 8 > 4x + 26.
Ox<9
Ox< 17
Ox>9
Ox> 17
Answer:
The answer is x>17
Step-by-step explanation:
First subtract 4x from both sides
6x - 8 > 4x + 26
-4x. -4x
2x - 8 > 26
8 is negative so to get rid of it add 8 to -8 and 26
2x - 8 > 26
+8. +8
2x > 34
x needs to be by itself so divide both sides by 2
2x > 34

x > 17
