Answer:
Barry's kart is faster as he goes 21 Mph while Alan only goes 19.89 Mph.
Step-by-step explanation:
First to get this answer we need to convert feet per minute to miles per hour. So we multiple 1750 feet per minute by 60 to get a hour. This gets up 105000 total feet in a hour. Now we need to divide this by 5280, which is how long a mile is, to get 19.89 miles which is how many miles he travels in a hour making him travel 19.89 mph which is less than 21 making Barry faster.
Can anyone help me with this?
re f(x) = 2x-5 and g(x)= Žx + 5
inverses? Explain.
We are being asked the inverse of the function f(x) = 2x - 5. Now by definition of an inverse function, f(g(x)) = x. f(x) = 2x - 5, so the inverse would be in the following format:
[tex]=> \mathrm{f\left(g\left(x\right)\right)\:=\:2g\left(x\right)\:\:-\:5}\:[/tex]
[tex]=> \mathrm{2g(x) - 5 = x}\:[/tex]
[tex]=> \mathrm{2g(x) = x + 5}\:[/tex]
[tex]=> \mathrm{g(x) = x + 5 / 2}\:[/tex]
I don't understand the inverse function you gave, 'g(x)= Žx + 5' but if it is in other words 'g(x) = x + 5 / 2' then the two functions you gave are inverses.

The number of sides of two regular polygons are as 5:4 and the difference between their angles is 9°. Find the number of sides of the polygons,
Answer:
8 and 10.
Step-by-step explanation:
I am assuming the difference of 9° is between their interior angles.
The formula for the interior angle of a regular polygon is 180° - 360°/n, where n is the number of sides.
As the number of sides increase, the interior angle increases.
Therefore 180° - 360°/(5x) = 180° - 360°/(4x) + 9°.
180° - 360°/(5x) = 180° - 360°/(4x) + 9°
360°/(4x) = 360°/(5x) + 9°
90°/x = 72°/x + 9x°/x
=> 90° = 72° + 9x°
9x° = 18°
x = 2.
Hence the number of sides of the regular polygons are 8 and 10.

Step-by-step explanation:
8 1/3 = 25/3
25/3 pages of a book in 10 minutes
Multiply both numbers by the reciprocal of 10, which is 1/10
25/3 x 1/10 = 25/30 = 5/6
So, Charlotte reads 5/6 pages of a book in 1 minute.
Which is equal to 75 1/3%

Solve for X:
-7x -1 = -9x -17
Answer:
-8.
Step-by-step explanation:
-7x - 1 = -9x - 17
-7x - (-9x) = -17 - (-1)
-7x + 9x = -17 + 1
2x = -16
x = -8.

what is the simplest form of 8√5 + √250 - √720? i’ve been crying over this for an hour pls help
Step-by-step explanation:
8√5 + √250 - √720
= 8√5 + (√2)(√5)(√25) - (√5)(√144)
= 8√5 + 5(√2)(√5) - 12√5
= √5 (8 + 5√2 - 12)
= √5 (5√2 - 4)
= √10 (5 - √2).

Please do step by step of how you did it PLEASE :)
Answer:
1 1/2 one and a half
Step-by-step explanation:
So we know 100% is 1 whole so we already know we have 1. 50% is half and if we put 1 and 1/2 together is gives us 1 1/2 one and a half hope this answered your question.
Answer:
1.50 is 150% in decimal form and 1 1/2 is in fraction form
Step-by-step explanation:
150 is over 100 so equals 1 whole
50 is left over
50 is half of 100 so 1/2 is the same fraction

Answer:
The Answer is actually B & E if doing this via Connexus. Connexus doesn't view putting an extra zero at the end to be incorrect (as it really isn't, it is just pointless) but Connexus does view NOT selecting that one as incorrect.
So while E is the correct answer, you will only get partial credit if you don't also select B. (With Connexus you can tell ones that are supposed to have multiple answers if they have check boxes instead of radio buttons.)

6. Toni can carry up to 18 lb in her backpack. Her lunch weighs 1 lb, her gym clothes weigh 2 lb, and her books (b) weigh 3 lb each. How many books can she carry in her backpack?
Do not use the equal sign, we're using the greater than sign > and the < less than sign!
Answer:
x≤ 5
Step-by-step explanation:
18-2-1=15
15/3=5
Answer:
the number of book she can carry is 5 books
Step-by-step explanation:
backpack capacity = 18 lb
backpack can carry:
lunch = 1 lb
gym clothes = 2 lb
books = 3 lb per book
find:
how many books can she carry in her backpack?
backpack capacity = lunch + gym clothes + x books
let x be the number of books
18 = 1 + 2 + 3x
18 - 1 - 2 = 3x
15 = 3x
x = 15 / 3
x = 5
therefore, the number of book she can carry is 5 books
