Amanda uses the recipe shown to make trail mix for a camping trip. How many cups of M&M's will she need to make 180 cups of trail mix?
Answer:
40 cups
Step-by-step explanation:
7 part nuts and 2 parts M&M makes up 1 trail mix
7 and 2 part = 9 parts in total
There are 180 cups in total, so each part would be:
180/9 = 20 cups = 1 part
Now, we know there are 2 parts M&Ms and there are 20 cups in a part, so:
M&Ms required = 2 * 20 = 40 cups

A right triangle has side lengths a, b, and c as shown below.
Use these lengths to find tanx, cosx, and sin x.
Step-by-step explanation:
step 1. tan x = opposite/adjacent = c/b
step 2. cos x = adjacent/hypotenuse = b/a
step 3. sin x = opposite/hypotenuse = c/a

Answer:
91 rad/s
Step-by-step explanation:
The relationship between angular velocity (ω) and constant angular acceleration (ω') is ...
ω(t) = ω0 + t·ω'
ω(0.25) = 95 = ω0 + 0.25(16)
95 -4 = ω0 = 91 . . . rad/s
The initial angular speed was 91 radians per second.

x° = 118°
y° = 180° - (22° + 180° - x°)
y° = 180° - (22° + 180° - 118°)
y° = 180° - 22° - 180° + 118°
y° = 118° - 22°
y° = 98°

The graph of y = f(x) is shown below. What are all of the real solutions of
f(x) = o?
Answer:
The real solutions are : -6, -3 and 2
Step-by-step explanation:
The solutions of a functions are the input values at an output zero
Graphical wise, this can be represented by the order pairs (x, 0)
In other words, these are the points that lie on the x-axis
Examining the given graph, we can see that the points lying on the x-axis are:
(-6, 0), (-3, 0) and (2, 0)
This means that:
The real solutions of the function are:
-6, -3 and 2

To express % as a decimal, move the decimal point ▼ two three one places to the ▼ left right and ▼ leave the number as it is. remove the dollar sign. divide by 100. remove the percent sign.
Question
To express 7.5 % as a decimal, _______, ___________ and remove the percent sign.
▼ move the decimal point [two] [three] [one] places to the [left] [right]
▼ leave the number as it is.
▼ remove the dollar sign.
▼ divide by 100.
Answer:
▼ move the decimal point [two] places to the [left]
▼ divide by 100.
Step-by-step explanation:
Given
[tex]Number = 7.5\%[/tex]
Required
Express as decimal [Select all correct options]
From the list of given options, the correct options are:
▼ move the decimal point [two] places to the [left]
▼ divide by 100.
To prove that the options are correct:
(1)
▼ move the decimal point [two] places to the [left]
7.5% becomes 0.075%
▼ Remove the percent sign
0.075% becomes 0.075
So:
[tex]7.5\% = 0.075[/tex]
(2)
Divide by 100
7.5% when divided by 100 is: 0.075%
Remove the % sign, we have: 0.075

A group of friends wants to go to the amusement park. They have $243.25 to spend on parking and admission. Parking is $15.75, and tickets cost $22.75 per person, including tax. How many people can go to the amusement park?
Answer: 10 people
Step-by-step explanation:
Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.
The amount spent on just tickets is therefore:
= 243.25 - 15.75
= $227.50.
If $227.50 was for tickets alone, the number of tickets they could buy is:
= Total amount left/ Price of tickets
= 227.50 / 22.75
= 10 people
