Sebastian is making bags of trail mix for hiking club. He will use 21 ounces of walnuts, 10.2 ounces of almonds, and 15.6 ounces of cashews. This amount makes 24 bags of trail mix. How many ounces are in each bag?

Answers

Answer:

1.95 ounces

Step-by-step explanation:

ounces in each bag = total ounces in 24 bags / number of bags

total ounces in 24 bags = 21 ounces of walnuts + 10.2 ounces of almonds + 15.6 ounces of cashews = 46.8 ounces

46.8 / 24 = 1.95 ounces

A collection of nickels and quarters is worth $2.10. There are 22 coins in all . How many of each coin
are there?

Answers

Answer:

17 nickels

5 quarters

Step-by-step explanation:

Let n = no. of nickels

22 - n = no. of quarters

Each quarter is 25 cents and each nickel is 5 cents

5n = total amount of money in cents for the nickels

25(22 - n) = total amount of money in cents for the quarters

Since the total amount of money is $2.10 or 210 cents we have the equation

5n + 25(22 - n) = 210

5n + 550 - 25n = 210

-20n + 550 = 210

-20n = -340

n = 17 nickels

22 - n = 22 - 17 = 5 quarters

Now, you don't need to do all that I did.  I explained in detail what is going on in this problem.  All that you would need to do is write this:

let n = no. of nickels

22 - n = no. of quarters      and then write the equation and solve

5n + 25(22 - n) = 210

??                                          OK?

The iron cross is a skiing trick in which the tips of the skis are crossed while the skier is airborne. Find the value of $x$ in the iron cross shown.

A photo shows the tips of the skis crossed each other while performing iron cross in skiing. Two pairs of opposite angles are formed during crossing. One pair of the opposite is labeled 127 degrees and left parenthesis 2 x plus 41 right parenthesis degrees. PS the image is the given degrees! PLLLSS help I am timed and I need to raise my grades!!!!

Answers

Answer:

43 = x

Step-by-step explanation:

well so you have 127 degrees = (2x + 41)

so get the x by itself

127 - 41 = 86

2x + 41 - 41 = 2x

86 = 2x

86 / 2 = 43

2x / 2 = x

43 = x  

The value of x is 43°.

Here,

The iron cross is a skiing trick in which the tips of the skis are crossed while the skier is airborne.

A photo shows the tips of the skis crossed each other while performing iron cross in skiing.

Two pairs of opposite angles are formed during crossing.

One pair of the opposite angle is 127° and (2x + 41)°.

We have to find the value of x.

What is Vertically opposite angles?

The angles opposite each other when two lines cross called Vertically opposite angles.

Now,

Two pairs of opposite angles are formed during crossing.

One pair of the opposite angle is 127° and (2x + 41)°.

Clearly, Both angle are equal;

2x + 41 = 127

2x = 127 - 41

2x = 86

x = 43

Therefore, Value of x is 43°.

You are organizing a school banquet. You spend $82 on decorations. Dinner will cost $13 for each person that attends. In the equation y=13x+82, y is the total cost of the banquet for x people. Complete the solution (69,?) to find the cost for 69 people.

Answers

Answer:

(69,979)

Step-by-step explanation:

In the coordinates, x is represented as 69. We can now insert this into the equation.

y = 13x + 82

Now to insert x.

y = 13(69) + 82

Now we can multiply 13 by 69.

13*69 = 897

Now fix the equation.

y = 897 + 82

Now add to get our y.

897 + 82 = 979

Substitute into the equation.

y = 979

And there is our answer. We now need to put this into the coordinates.

And we get our final answer of (69,979).

Hope this helps. Have a nice day.
