Step-by-step explanation:
Ali and Omar cycle around a cycle track.
Ali cycles each lap in 50 seconds.
Omar cycles each lap in 80 seconds.
Ali and Omar start cycling at the same time at the start line.
Work out how many laps they will each have cycled when they are next at the start line together
Answers
Answer and step-by-step explanation:
First, we will have to know at what time they will cross the line at the same time. So we can do the equation:
50 * 80 = 400
That means in 400 seconds they will be level again. Now, let's find Ali's amount of laps for 400 seconds, if it takes Ali 50 seconds for one lap. We can do:
400/50 = 8
This means it will take Ali 8 seconds to be leveled with Omar. Now Omar has the equation:
400/80 = 5
Because it takes him 80 seconds to take one lap. Therefore, it will take Ali 8 laps, and Omar 5 laps to be at the same starting line. Hope this helps!

Brandon is analyzing the profits from two of his restaurant locations. The first location showed a profit of $3,000 in the first week of the year but
has a showed a steady decrease in profits of 1.5% each week since then.
His second location showed a profit of $1,500 in the first week of the year and has showed a steady increase in profits of 1.2% each week since
then.
Which system of equations can Brandon use to determine the number of weeks, x, until the profits, y, from the two locations are the same?
ОВ.
OA y = -3,000(0.985)
y = 1,500(1.012)
y = 3,000(1.015)"
y = 1,500(1.012)"
OC.
y = -3,000(1.015)"
y = 1,500(1.012)
y = 3,000(0.985)

OD.
Answers
Answer:
y=3,000(0.985)^x
y=1,500(1.012)^x
Step-by-step explanation:
System of equations Brandon can use for two location are y= 3000[tex](0.985)^{x}[/tex] and y =[tex]1500(1.012)^{x}[/tex]
What is profit and loss percentage?Profit and loss percentage are used to refer to the amount of profit or loss that has been incurred in terms of percentage.
According to question
Brandon is analyzing the profits from two of his restaurant locations.
where
x = number of week
y = the profit
1st restaurant : showed a profit of $3,000 in the first week of the year but
has a showed a steady decrease in profits of 1.5% each week since then
So in equation we can write it as
y= [tex]3000(1 - 0.015)^{x\\}[/tex]
y= 3000[tex](0.985)^{x}[/tex]
2nd restaurant : showed a profit of $1,500 in the first week of the year and has showed a steady increase in profits of 1.2% each week since then.
So in equation we can write it as
y = [tex]1500(1+0.012)^{x}[/tex]
y =[tex]1500(1.012)^{x}[/tex]
Hence, system of equations can Brandon use to determine the x and y form the two location are y= 3000[tex](0.985)^{x}[/tex] and y =[tex]1500(1.012)^{x}[/tex]

mine the volume if its length is 18 inches
Answers
Given:
The base of a prism is a right triangle with legs measuring 16 feet and 4 feet.
Height of the prism is 14 feet.
To find:
The volume of the triangular prism.
Solution:
The area of a triangle is:
[tex]Area=\dfrac{1}{2}\times b\times h[/tex]
Where, b is base and h is height of the triangle.
The base of a prism is a right triangle with legs measuring 16 feet and 4 feet. It means the base of the triangle is 16 feet and height is 4 feet. So, the area of the base of the prism is:
[tex]B=\dfrac{1}{2}\times 16\times 4[/tex]
[tex]B=32[/tex]
Now, the volume of a triangular prism is:
[tex]V=Bh[/tex]
Where, B is base area and h is the height.
Putting [tex]B=32,h=14[/tex] in the above formula, we get
[tex]V=32\times 14[/tex]
[tex]V=448[/tex]
Therefore, the volume of the triangular prism is 448 cubic feet.

x + 6x + 40 + 3x + 100 = 360
10x + 140 = 360 ( subtract 140 from both sides )

Barry the Beaver gnaws his way through a circular section of wood. The sector has a radius of 5.90 m and central angle 85.3°. What is the area of this section of wood?
Answers
Answer:
25.899sq.metres
Step-by-step explanation:
Area of this section of wood = Area of the sector
Area of the sector = theta/360 * πr²
r is the radius
theta is the central angle
Substitute
Area of the sector = 85.3/360 * πr²
Area of the sector = 85.3/360 * 3.14(5.90)²
Area of the sector = 85.3/360 * 109.3034
Area of the sector = 9,323.58002/360
Area of the sector = 25.899
Hence the area of the section of wood is 25.899sq.metres

Find the distance between points B and C on the graph.
Answers
Answer: BC = 5.83
Step-by-step explanation:
Luckily, the triangle is placed on the graph nicely so we can count the legs of the triangle:
AB = 5
AC = 3
BC = ?
To find BC, we can simply use the Pythagorean Theorem:
[tex]a^{2}+b^{2}=c^{2}[/tex]
5^2 + 3^2 = c^2
25 + 9 = c^2
34 = c^2
Now square root to find c, or BC.
[tex]\sqrt{34}=\sqrt{c^{2} }[/tex]
c = 5.83 (rounded by nearest hundredth)
