suppose that the current canadian dollar to US dollar exchange rate is 0.80 CAD = $1 US and that the U.S. dollar price of an Apple iphone is $320 what is the Candian dollar price of iphone?
Answer: 256 CAD
Step-by-step explanation:
Hi, to answer this question we simply have to multiply the price in US dollars of the iphone (320) and multiply it by 0.80 ( Canadian dollar to US dollar exchange rate)
Mathematically speaking:
Since:
$1 US = 0.80 CAD
$320 x0.80 = 256 CAD

AE is 9. ED is 6. The triangle ABE is proportional to ACD, so their sides are proportional. For example, AE:ED = AB:BC. So, ED/AE = 2/3 = BC/AB. This gives us 2/3 = x/10, which gives us x=6.6667

Olga is putting a border around her triangular flower bed. She has 20 feet of border material, which will fit perfectly around the bed. She wants to make the flower bed larger by tripling the length of each of its sides. How much border material will she need in total?
Answer:
60 feet
Step-by-step explanation:
We know that a triangle has 3 sides, in this case we will call them a, b and c.
It tells us that everything is material, it measures 20, that is:
a + b + c = 20
They tell us that she wants to triple each side and to know how much material she would need in total. Then it would be:
border material need = 3 * a + 3 * b + 3 * c
common factor 3:
border material need = 3 * (a + b + c)
border material need = 3 * 20
border material need = 60
Which means that she needs a total of 60 feet of material.
Answer: She would need 60 ft of border material.
Step-by-step explanation: Olga has a triangular flower bed, which means her flower bed is three sided. Also it has been stated that she has 20 feet of border material available. which will fit perfectly around the bed. This also means the perimeter of her flower bed is 20 feet.
Assuming the sides of her flower bed are labeled as a, b and c. Then a plus b plus c would equal 20, since the perimeter is the addition of all sides of the triangle.
However, she intends to triple the length of each side of the flower bed, and that would translate into the sides being 3a, 3b and 3c respectively. This effectively triples the length of the perimeter which is shown as,
Perimeter = a + b + c
20 = a + b + c
3(20) = 3a + 3b + 3c
60 = 3a + 3b + 3c
Therefore, she is going to need more border material and that is calculated as 60 feet.

5(z + 1) = 3(z + 2) + 11 Solve for Z
Answer:
z=6
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
5(z + 1) = 3(z + 2) + 11
5z + 5 = 3z + 6 + 11
5z + 5 = 3z + 17
5z = 3z + 12
2z = 12
2z/2 = 12/2
z = 6
:)
Answer:
z= 6
Step-by-step explanation:
5(z + 1) = 3(z + 2) + 11
Distribute
5z+5 = 3z+6+11
Combine like terms
5z+5 = 3z+17
Subtract 3z from each side
5z+5-3z = 3z-3z+17
2z+5 = 17
Subtract 5 from each side
2z+5-5 = 17-5
2z = 12
Divide each side by 2
2z/2 =12/2
z = 6
The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse. Which is an equivalent equation solved for y? y = a · πx y = a + (πx) y = a – πx y = a ÷ (πx)
Answer:
Step-by-step explanation:
If [tex]A =\pi xy[/tex], then π, x, and y are all multiplied together. Multiplication is undone by division, so we will divide away the πx to solve for y:
[tex]\frac{A}{\pi x}=y[/tex] which is your last option.
Here, we are required to find an equivalent equation solved for y if the area, a is given by;
a = πxy
An equivalent equation solved for y is;
y = a ÷ (πx)
To find an equivalent equation solved for y,
We have to make y the subject of the formula in;
a = πxy.
Therefore, by dividing both sides of the equation by πx, so that y is left alone on the right hand side.
Therefore, y = a ÷ (πx).

In the late 18th century, a decimal clock was proposed, in which there were 100 'minutes' in one 'hour' and 10 'hours' in one day. Assuming that such a clock started from 0:00 at midnight, what time would it show when an ordinary clock showed 6am?
Answer:
2:50
Step-by-step explanation:
On an ordinary clock, there are 24 hours.
1) 6/24 = 0.25 (The percentage in which the day has passed)
2) 10 (total hours in a day in the decimal clock) * x 0.25 = 2.50
3) 2.5 Hours. On a typical clock, that would read 2:30, however, because the decimal clock proposes that there are 100 minutes in one hour, it will be 2:50, Therefore, the clock will display 2:50
The time that is shown in a decimal clock when it is 6 am in the ordinary clock is 2:30 am.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

One day = 10 hours
Ordinary clock:
One day = 24 hours

One quarter is 6 hours.
Now,
Number of hours in one quarter in the decimal clock

Find angle x°,y°,z°.
Answer:
x = 22°
y = 26°
z = 48°
Step-by-step explanation:
∠PQS and ∠QSR is a pair of alternate interior angles
plus PQ is parallel to SR
then
x = 22°
SPR is an isosceles triangle then m∠PRS = 66°
Therefore x + y = 180-(66+66) = 180-132 = 48
then y = 48 - x = 48-22 = 26
finally, z = x + y = 48
Answer:
x = 22
y = 26
z = 48
Step-by-step explanation:
ΔSPR is isosceles, meaning two angles are equal, as indicated.
one base angle is 66, meaning the other one is also 66.
alternate angles are equal ; angle Q = angle S = 22 = x
To find the other angle of the triangle below, add 22 and 66 and subtract from 180 to get 92.
vertically opposite angles are equal ; 92
88 88
92
the triangle on the upper right has 92, 22, and the missing angle which is 66.
the upper left triangle has 88, 66 and the missing which is 26 = y
the straight line above(PQ), now has 66, 66 and the missing one .add , then take away from 180 to get 48 = z

A total of 70 tickets were sold for a concert and earn the organizers $804. If the cost of each ticket is either $10 or $12, how many tickets of each type were sold?
Answer:
X=18
Y=52
Step-by-step explanation:
Let X represent the first type of ticket sold at the concert
Let Y represent the second type of ticket sold at the concert-----equation 1
X + Y= 70 (Total number of tickets sold) ------equation 2
(X×10) + ( Y×12)=$804. ( Total money generated in the concert
Since,
X+Y= 70
X= 70-Y
Substitute (70-Y) for X in equation 2
(70-Y)×10 + Y×12=804
700-10Y+12Y= 804
Collect the like terms
700+2Y=804
2Y=804-700
2Y= 104
Divide both sides by the coefficient of Y which is 2
2Y/2= 104/2
Y=52
Substitute 52 for Y in equation 1
X+Y=70
X+ 52=70
collect the like terms
X= 70-52
X=18
Hence the first type of ticket sold is 18 tickets and the second type of ticket sold is 52 tickets.

Answer:
x=36
Step-by-step explanation:
The angles in a triangle must add to 180 degrees.
Therefore,
x+65+79=180
Add 65 and 79
x+144=180
We want to solve for x. In order to do this, we have to get x by itself. 144 is being added to x (+144)The opposite of addition is subtraction, so subtract 144 from both sides(-144)The +144 and -144 will cancel out, and leave x by itself.
x+144-144=180-144
x=180-144
x=36
Let’s check our answer. Add all the angles together, and make sure they equal 180 degrees.
x+65+79
We know x is equal to 36, so we can substitute it in
36+65+79
180
The 3 angles add to 180, so we know that x=36
