Plane A leaves the Calgary airport at a bearing of 70 degrees and travels a distance of 420km. Plane B leaves the Calgary airport at a bearing of 280 degrees and travels a distance of 340km. How far apart are the planes to the nearest kilometre.
Answer:
16650 km
Step-by-step explanation:
If plane A leaves from Calgary airport at a nearing of 70 degree, it would end up on the first quadrant. Since we are not given exact bearing here we would assume both planes begin from the first quadrant, they move from North. Example plane A moves North 70 degrees.
Plane B will move North 280 degrees and end up in the fourth quadrant (because each quadrant is 90 degrees so we would have 90+90+90+10=280)
Distance apart = 70+80=150 degrees( since all four quadrants =360 degrees)
1 degree= 111km (approximate metric equivalent of degrees)
Therefore distance apart = 150 degrees ×111km = 16650km

Raheem made 14 ounces of curry sauce which contained (among other things), 3.25 ounces of spices. He wants to make a larger batch for a family dinner and decides he will need a total of 84 ounces of sauce altogether. How many ounces of spices will he need to complete his recipe?
Answer:
19.5 ounces of spices
Step-by-step explanation:
Raheem made 14 ounces of curry sauce which contained (among other things), 3.25 ounces of spices. He wants to make a larger batch for a family dinner and decides he will need a total of 84 ounces of sauce altogether. How many ounces of spices will he need to complete his recipe?
The question above is calculated as:
14 ounces of sauce = 3.25 ounces of spices
84 ounces of sauce = x ounces of spices
Cross Multiply
14x = 84 × 3.25
x = 84 × 3.25/14
x = 19.5 ounces of spices
Hence, for 84 ounces of curry sauce he would need 19.5 ounces of spices
A junior one-day admission to an amusement park is $26. This price is increased by %70 for adults. Find the mark-up and the adult price. The mark-up is nothing.
Answer:
The price for adults would be $44.20
Step-by-step explanation:
There are 2 ways to solve this problem
1) You can multiply 26 by 0.7 and then add That to 26
Or
2) You can just multiply 26 by 1.7
You get the same answer for both ways
So first way
26*0.7 is 18.2
Now add 18.2 to 26
You’ll get 44.20
Second way
26*1.7. I multiplied by 1.7 becuase its a markup of 70 percent, th kid’s price is already 100 percent and for adult its an extra 70 percent so the china ally we’re paying 170 percent for the adult ticket
Now multiplying by 170 percent is basically the diamond 1.7
so 26*1.7 is 44.2

A town has a population of 43,650 and 75 people move out every month 125 move in every month. If a town near has a population of 45,225 but 125 people move out every month how many months until they have the same population?
Answer:
361.8
Step-by-step explanation:
The equation of the first Population can be given by
Population of the town A= 43650+50x
The equation of the second Population can be given by
Population of the town B= 45225-125x
For population B to catch up to population A, we have 125×361.8( since 45225/125=361.8)

suddenly the number of math problems mathletes had to solve increased by 60%! to keep on track the mathletes try to go faster but only increase their speed by 25% By what percent must the number of mathletes on the team increase so they can solve all the problems on time?
9514 1404 393
Answer:
28%
Step-by-step explanation:
If x represents the fractional increase in the number of mathletes, and if problem-solving speed is jointly proportional to their speed and their number, we want ...
(1 +25%)(1 +x) = (1 +60%)
1 +x = 1.60/1.25 = 1.28
x = 0.28 = 28%
The team size must increase by 28% to solve all of the problems on time.

factorize py+ pz + y² + yz
Answer:
you could either say p(y+z)+y(y+z)or y(p+y)+ z(p+y)
Step-by-step explanation:
I cant really explain it but I hope this helps
Answer: [tex](p+y)(y + z) \\\\[/tex]
=======================================
Work Shown:
[tex]py + pz + y^2 + yz \\\\(py + pz) + (y^2 + yz) \\\\p(y + z) + (y*y + yz) \\\\p(y + z) + y(y + z) \\\\(p+y)(y + z) \\\\[/tex]
I grouped the terms into pairs. Then I factored the GCF from each pair
The GCF of py+pz is p
The GCF of y^2+yz is y
On the last line, I factored out the overall GCF (y+z)
You can use the FOIL rule or the distributive property to expand out (p+y)(y+z) and you should get the original expression back again. This is a way to confirm the correct answer.

Which values are within the range of the piecewise-defined function?
f(x) =
2 x + 2 x < - 3
X x = -3
- x - 2 X > -3
y = -6
y=-4
y=-3
y = 0
y = 1
y = 3
Answer:
-6, -4, -3, 0
Step-by-step explanation:
I just did this question and got it right.
-6, -4, -3, and 0 are the values which are within the range of the piecewise-defined function.
Correct options: a) y = -6, b) y = -4, c) y = -3, d) y = 0
Here, we have, to determine which values are within the range of the piecewise-defined function, we need to evaluate the function for each given value of y.
Given piecewise-defined function:
f(x) =
2x, x < -3
x, x = -3
-x - 2, x > -3
Let's evaluate the function for each value of y:
a) y = -6
For y = -6, we need to find x such that f(x) = -6.
-6 is in the range of the function if there exists an x such that f(x) = -6.
For x < -3: f(x) = 2x
2x = -6
x = -3
For x = -3: f(x) = x
x = -3
For x > -3: f(x) = -x - 2
-x - 2 = -6
x = 4
Since there is a value of x (-3) that satisfies f(x) = -6, option a) y = -6 is correct.
b) y = -4
For y = -4, we need to find x such that f(x) = -4.
-4 is in the range of the function if there exists an x such that f(x) = -4.
For x < -3: f(x) = 2x
2x = -4
x = -2
For x = -3: f(x) = x
x = -3
For x > -3: f(x) = -x - 2
-x - 2 = -4
x = 2
Since there is a value of x (-3) that satisfies f(x) = -4, option b) y = -4 is correct.
c) y = -3
For y = -3, we need to find x such that f(x) = -3.
-3 is in the range of the function if there exists an x such that f(x) = -3.
For x < -3: f(x) = 2x
2x = -3
x = -1.5
For x = -3: f(x) = x
x = -3
For x > -3: f(x) = -x - 2
-x - 2 = -3
x = 1
Since there is a value of x (-3) that satisfies f(x) = -3, option c) y = -3 is correct.
d) y = 0
For y = 0, we need to find x such that f(x) = 0.
0 is in the range of the function if there exists an x such that f(x) = 0.
For x < -3: f(x) = 2x
2x = 0
x = 0
For x = -3: f(x) = x
x = -3
For x > -3: f(x) = -x - 2
-x - 2 = 0
x = -2
Since there is a value of x (-3) that satisfies f(x) = 0, option d) y = 0 is correct.
e) y = 1
For y = 1, we need to find x such that f(x) = 1.
1 is in the range of the function if there exists an x such that f(x) = 1.
For x < -3: f(x) = 2x
2x = 1
x = 0.5
For x = -3: f(x) = x
x = -3
For x > -3: f(x) = -x - 2
-x - 2 = 1
x = -3
Since there is no value of x that satisfies f(x) = 1, option e) y = 1 is incorrect.
f) y = 3
For y = 3, we need to find x such that f(x) = 3.
3 is in the range of the function if there exists an x such that f(x) = 3.
For x < -3: f(x) = 2x
2x = 3
x = 1.5
For x = -3: f(x) = x
x = -3
For x > -3: f(x) = -x - 2
-x - 2 = 3
x = -5
Since there is no value of x that satisfies f(x) = 3, option f) y = 3 is incorrect.
Correct options: a) y = -6, b) y = -4, c) y = -3, d) y = 0
The correct values within the range of the piecewise-defined function are -6, -4, -3, and 0.

Solving systems of equations using substitution/eliminationSolving systems of equations by graphingStep-by-step explanation:
Step 1: Define systems
y = x + 9x + 5
y = -x + 11x + 29
Step 2: Simplify systems
y = 10x + 5
y = 10x + 29
Step 3: Solve for x
Substitution
Substitute in y: 10x + 5 = 10x + 29Subtract 10x on both sides: 5 ≠ 29Here we see that 5 does not equal 29.
∴ The systems has no solutions.
Step 4: Graph systems
Check the solution set (if applicable).
We see that the 2 lines are parallel and will never intersect. Therefore, this proves that our systems has no solution.
