Answer:
162 km per hour
Step-by-step explanation:
Hi!
Speed=Distance x Time
So... 3 x 54 = 162
Hope this helps :)
Answer:
18km/h
Step-by-step explanation:
Well. Speed = Distance x Time
So if she travelled for 3 hours. In that time, she must have travelled 54km.
Average speed is given as kilometres per hour or km/h
So all we need to do is 54/3 which gives us 18km/h
I hope that helps! ^-^
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!!!!
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°.

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?
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
3/5(a + 5.25) = 7.35 What does a equal
Answer:
a = 7
Step-by-step explanation:
Let's solve your equation step-by-step.
3/5(a+5.25)=7.35
Step 1: Simplify both sides of the equation.
3/5(a+5.25)=7.35
(3/5)(a)+(35)(5.25)=7.35 (Distribute)
3/5a+3.15=7.35
Step 2: Subtract 3.15 from both sides.
3/5a+3.15−3.15=7.35−3.15
3/5a=21/5
Step 3: Multiply both sides by 5/3.
(5/3)*(3/5a)=(5/3)*(21/5)
a=7

You and three friends buy 4 movie tickets. Each person buys a $3 popcorn. The total cost is $72. Letx represent the cost of 1 movie ticket Write an equation for
the total cost
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.
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.

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

Find the missing length indicated. (Triangle inequality theorem) please help
Answer:
Step-by-step explanation:
Oh they are " similar " triangles, so they are scale copies of each other
for 13) they are saying those same marks on the sides means those segments are the same lengh. so the bigger triangle takes 2 same lengths as does the smaller one. Yes.. that does mean the bigger one is 2 times bigger than the smaller one. sooo just multiply that known side by 2 to find BD
so BD = 2 *8
BD = 16 :)
for 14) same exact thing but in reverse
XY = 1/2 *8
XY = 4 :)
for 15)
I think that there is a line.... from U to V that isn't showing up in the photo, using your camera for a photo of a screen seems .. hmm redundant.. just push "screen print" then paste what you copied into paint . then show that pic... no phone cam required. :? and the pic would be much much better quality.. no missing lines :/
anyway so if there is in fact a line from U to V then IK is that same 2 times bigger than UV
IK = 2*4
IK = 8
For 16) this is getting to be the same thing over and over.. are you getting it? :)
DF = 2 *8
Df = 16
Americans consume on average 92 pounds of chicken per year, with a standard deviation of 10.3 pounds. What is the probability that a sample of 50 people will have consumed an average of 100 pounds or more?
Answer:
0.2187
Step-by-step explanation:
Americans consume on average 92 pounds of chicken per year, with a standard deviation of 10.3 pounds. What is the probability that a sample of 50 people will have consumed an average of 100 pounds or more?
We to find
x ≥ 100 pounds
To solve for the above question, we use the z-score formula
z = (x-μ)/σ, where
x is the raw score = 100 pounds
μ is the population mean = 92 pounds
σ is the population standard deviation = 10.3
Hence:
z = (100 - 92)/ 10.3
z = 8/1.46
z = 0.7767
Probability value from Z-Table:
P(x<100) = 0.78133
P(x>100) = 1 - P(x<100) = 0.21867
Approximately = 0.2187
Therefore, the probability that a sample of 50 people will have consumed an average of 100 pounds or more is 0.2187
