Answer:
7 minutes
Step-by-step explanation:
The computation of the number of minutes that climbs the stairs tomorrow is shown below:
Given that
He claimed 1000 stairs in 25 minutes
So for 280 stairs, he would take
= 280 × 25 minutes ÷ 1000 minutes
= 7000 ÷ 1000
= 7 minutes
hence, 7 minutes would be taken
The same is to be considered
Answer:
7 minutes

What is the sum of the measures of interior the angles of a 25-gon
Answer:
4,140 degrees
Step-by-step explanation:
Mathematically, the sum of interior angles of a polygon is;
(n-2)180
where n is the number of sides the polygon has
Mathematically;
we will be replacing n by 25 here
So, we have;
(25-2)180
= 23 * 180 = 4,140 degrees
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?
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

7) The base of a prism is a right triangle with legs measuring 16 feet and 4 feet. If the height of the prism is
14 feet, find its volume.
mine the volume if its length is 18 inches
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.

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)
y = 1,500(1.012)"
OD.
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]

Answer:
the line plot in the bottom right corner
Step-by-step explanation:
Answer:
D is the correct graph.
Step-by-step explanation:
First you put the entries in ascending order, because that's how the line plot needs to be ordered.
1/4, 3/8, 1/2, 3/4, 7/8, 1, 1 1/4
So right there, you can rule out A.
You can rule out C because 1/4 does not occur 5 times in the data set.
B is incorrect because 3/8 isn't on the line plot at all.

Find the area of the shaded region of the square, with side length 2x - 3, if each of
the ovals has an area of x – 5 square inches.
Answer:
4x^2 - 14x + 19
Step-by-step explanation:
A = LW
A = (2x-3) (2x-3)
4x^2 - 6x - 6x + 9
Combine like terms:
4x^2 - 12x + 9
-2(x - 5) (for both ovals)
(4x^2 - 12x + 9) -2(x - 5)
4x^2 - 12x + 9 - 2x + 10

Answer:
<AEB = 51.2
Step-by-step explanation:
Remark
A straight line has a degree value of 180. There are 3 angles. One of them is 90. The other two must add to 90
Equation
2.7x + 8 + 3.8x - 22 = 90 combine like terms on the left.
6.5x - 14 = 90 add 14 to both sides
6.5x = 90 + 14
6.5x = 104 Divide by 6.5
x = 104/6.5
x = 16
<AEB = 2.7*16 + 8
<AEB = 51.2

As part of statistics project, math class weighed all the children who were willing to participate as shown below.
How many children weighed less than 50 pounds?
Answer:
18
Step-by-step explanation:
The key of this leaf stem-leaf plot is:
4 | 5 = 45
Therefore, the data points that represents children with weight that is less than 50 pounds would be as follows:
First row => 12, 13, 15, 15 15, 16, 16, 19
Second row => 23, 25
Third row => 33, 35, 37, 38, 39
Fourth row => 44, 45, 45
Therefore, the number of children that weigh less than 50 pounds = 18
Ryan has 7 black pairs of socks, 3 pair of brown socks, and 8 white pairs of socks in his wardrobe. He randomly picks one pair. Find P(NOT Black) in fraction form
Answer:
Black socks pairs = 7
Brown socks pairs = 3
White socks pairs = 8
P(not black) = ?
First, you need to add the brown & white socks pairs,
[tex]3 + 8 = 11[/tex]
Then you need to add the total number of socks pairs,
[tex]7 + 3 + 8 \\ = 7 + 11 \\ = 18[/tex]
P(not black)
[tex] = \frac{11}{18} [/tex]
Step-by-step explanation:
solution given:
total pair of socks[S]=(7+3+8)=18
total pair of black socks[B]=7
total pair of brown socks [C]=3
total pair of white socks[W]=8
total no of orange marbles[O]=2
now
the P( not black) =?
we have
P( not black) =1-[tex] \frac{n[B]}{n[S]} [/tex]
P( not black) =1-[tex] \frac{7}{18} [/tex]
P( not black) =[tex] \frac{18-7}{18} [/tex]
P( not black) =[tex] \frac{11}{18} [/tex]
so 11/18 is a required probabilty.
The population P, of Caribou in the Yukon is modeled by P=6x^2-120x+1250 where X is the number of years from today. After how many years with the Caribou population route 21,000 round to one decimal place
Answer:
It will take approximately 68.2 years for the Caribou population to reach 21,000.
Step-by-step explanation:
The population P of Caribou in the Yukon is modeled by P=6x²-120x+1250 where x is the number of years from today.
If the population P of Caribou in the Yukon is 21000, then, replacing you get:
21000= 6x²-120x+1250
So:
0= 6x²-120x+1250 -21000
0= 6x²-120x - 19750
This is a quadratic function of the form: 0= ax²+ bx +c, where: a=6, b= -120 and c=-19750
To solve a quadratic function and determine the value of x you can use the expression:
[tex]x1,x2=\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}[/tex]
Replacing the values of a, b and c and solving you get:
[tex]x1,x2=\frac{-(-120)+-\sqrt{(-120)^{2}-4*6*(-19750) } }{2*6}[/tex]
[tex]x1,x2=\frac{120+-\sqrt{14400+474000 } }{12}[/tex]
[tex]x1,x2=\frac{120+-\sqrt{488400 } }{12}[/tex]
[tex]x1,x2=\frac{120+-698.86 }{12}[/tex]
So:
[tex]x1=\frac{120+698.86 }{12}[/tex]
x1= 68.24 ≅ 68.2
and
[tex]x2=\frac{120-698.86 }{12}[/tex]
x2= -48. 24 ≅ -48.2
As time cannot be negative, it will take approximately 68.2 years for the Caribou population to reach 21,000.

Find the distance between points B and C on the graph.
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
