Answer:
x = 1851851.851....
Step-by-step explanation:
Given statement:
2.7% of x equals 50,000.
When we convert the statement into an equation, we get;
⇒ 2.7% × x = 50,000
A percentage is always written as (Percent)/100 in fraction form. Thus;
⇒ 2.7/100 × x = 50,000
Using cross multiplication:
⇒ 2.7 × x = 50,000 × 100⇒ 2.7 × x = 5,000,000To determine the value of x, we need to isolate it. This can be done by dividing the cooeficient of x both sides.
Divide both sides by 2.7
⇒ (2.7 × x)/2.7 = 5,000,000/2.7⇒ x = 1851851.851....Answer:
Percent in decimal form:
[tex]\sf 2.7\% = \dfrac{2.7}{100} = 0.027[/tex]
Therefore:
27% of X = 50000
[tex]\sf \implies 0.027 \cdot X=50000[/tex]
[tex]\sf \implies X=\dfrac{50000}{0.027}[/tex]
[tex]\sf \implies X=\dfrac{50000 \times 1000}{0.027 \times 1000}[/tex]
[tex]\sf \implies X=\dfrac{50,000,000}{27}\quad \textsf{(as a fraction)}[/tex]
[tex]\sf \implies X=1,851,852\quad \textsf{(nearest whole number)}[/tex]

The length of the line segment AM, which is a part of line segment AB when it is divided into two equal parts by Midpoint M is 14 units.
What is midpoint?For a line segment, mid-point is the middle point of it which divides the line segment into the two equal parts.
Let assume "M" is the midpoint of the segment AB. The value of has to be found out. It is given that,
[tex]AM= x+7 \\MB=2x[/tex]
In this line segment AB, M is midpoint. Thus, it divide the line segment into two equal parts of AM and MB. Thus,
[tex]x+7=2x\\2x-x=7\\x=7[/tex]
Put the value of x in AM,
[tex]AM=x+7\\AM=7+7\\AM=14\rm\; units[/tex]

At a Harare swimming club, there are 35 girls and 25 boys. . In a Bulawayo swimming club, there are 22 girls and 14 boys. Which swimming club has the greatest proportion of girls? Explain how you worked out your answer.
Answer:
Bulawayo
Step-by-step explanation:
Proportions can be compared numerous ways. Here, we find it convenient to look at the difference between girls and boys relative to the number of boys.
__
HarareWith 35 girls and 25 boys, there are 10 more girls than boys. 10 is less than half of the number of boys, so the ratio of girls to boys is less than 1.5.
BulawayoWith 35 girls and 15 boys, there are 8 more girls than boys. 8 is more than half of the number of boys, so the ratio of girls to boys is more than 1.5.
Comparision"More than 1.5" is greater than "less than 1.5", so Bulawayo has the greatest proportion of girls.
_____
Additional comment
As a fraction of the total, the proportions of girls are ...
Harare: 35/(35+25) = 35/60 = 7/12 = 21/36
Bulawayo: 22/(22+14) = 22/36 . . . . . . greater than 21/36.
Which of the following scenarios MUST represent two independent events?
P(blue) = 20%, P(green) = 60%, P(blue and green) = 13%
P(blue) = 40%, P(green) = 30%, P(blue and green) = 13%
P(blue) = 70%, P(green) = 30%, P(blue and green) = 21%
P(blue) = 80%, P(green) = 20%, P(blue and green) = 18%
Answer: C) P(blue) = 70%, P(green) = 30%, P(blue and green) = 21%
Step-by-step explanation:
Given probabilities P(A) AND P(B) are independent, the probability that both events to occur is given by:
P(A)∩P(B)
thus from the example, independent events will be:
P(blue)=70%, P(green)=30%, P(blue and green)=21%
Because:
P(blue)∩P(green)=0.7×0.3=0.21=21%

Ms. King wants to add a triangular deck in
the yard behind her house. Each side is to be
18 feet long. Find the length of the railing
that will fit completely around the deck.
Then find the area of the deck.
The length of the railing that will fit completely around the deck is 54 feet. The area of the triangular deck is approximately 164.25 square feet.
To find the length of the railing that will fit completely around the triangular deck, we need to calculate the perimeter of the triangle. The perimeter of a triangle is the sum of the lengths of all three sides.
Since each side of the triangular deck is 18 feet long, the perimeter (P) can be calculated as:
P = 18 feet + 18 feet + 18 feet
P = 54 feet
So, the length of the railing that will fit completely around the deck is 54 feet.
Next, let's find the area of the triangular deck. The area of a triangle can be calculated using the following formula:
Area (A) = (1/2) * base * height
Since the triangle is equilateral (all sides have the same length), any side can be considered as the base, and the height can be drawn from any vertex to the midpoint of the opposite side.
Let's consider one of the sides (18 feet) as the base. Now, to find the height, we can draw a perpendicular line from the vertex to the midpoint of the base, creating two right-angled triangles.
The height (h) of one right-angled triangle can be found using the Pythagorean theorem:
[tex]h^2 = (18 feet / 2)^2 + (18 feet)^2\\h^2 = 9 feet^2 + 324 feet^2\\h^2 = 333 feet^2\\[/tex]
h ≈ √333 feet
h ≈ 18.25 feet (rounded to two decimal places)
Now, we can find the area (A) of the triangular deck:
A = (1/2) * base * height
A = (1/2) * 18 feet * 18.25 feet
A ≈ 164.25 square feet (rounded to two decimal places)
So, the area of the triangular deck is approximately 164.25 square feet.

diameter of 8 in. and a height of 8 in.. How many cupfuls of water will it take for him
to empty his sink using each cup?
In your answer, give the number of cupfuls it will take to empty the sink using each
cup, and then explain how you calculated it.
Answer:
The green would take 4 and the blue would take 16 times respectivly. I did it by finding the volumes of the cups in terms of pi, then dividing it by the volume of the sink.
Step-by-step explanation:
So the volume of the whole half sphere is 512pi.

(–1, 3)

The point which is not included in the solution set for the inequality of the two-variable inequality shown in the graph is (-1,3).
How to graph the inequality?Inequality of a graph is represented with the greater then(<), less then(>) or with the other inequity signs. The inequality line on the graph is represented with the dotted lines.
A two-variable inequality is shown in the graph. It is a parabola. The vertex form of parabola is the equation form of quadratic equation which is used to find the coordinate of vertex points at which the parabola crosses its symmetry.
The standard equation of the vertex form of parabola is given as,
[tex]y=a(x-h)^2+k[/tex]
Here, (h, k) is the vertex point. In the graph, vertex points are (1,2). Thus, the equation become,
[tex]y=a(x-1)^2+2\\[/tex]
By the point of graph (0,3), find the value of a,
[tex]3=a(0-1)^2+2\\3=a+2\\a=3-2\\a=1[/tex]
Thus, the equation become,
[tex]y=1(x-1)^2+2\\y=x^2-2x+1+2\\y=x^2-2x+3\\[/tex]
The graph of this line is attached below. In this graph only point (-1,3), does not fall hence, does not satisfy the equation.
Thus, the point which is not included in the solution set for the inequality of the two-variable inequality shown in the graph is (-1,3).

2 hours 17 minutes
2 hours 48 minutes
1 hour 53 minutes
2 hours 19 minutes
1 hour 38 minutes
The team’s overall score is the average number of minutes it takes for its members to complete the course. What is this team’s score?
Step-by-step explanation:
the average is the sum of all data points divided by the number of data points (5).
2 hours 17 minutes
2 hours 48 minutes
1 hour 53 minutes
2 hours 19 minutes
1 hour 38 minutes
------------------------------
8 hours 175 minutes
175 minutes = 2 hours 55 minutes
so, we need to add this to the 8 hours and get
10 hours 55 minutes
this we need to divide by 5 for the average time
(10 hours 55 minutes) / 5 = 2 hours 11 minutes =
= 2×60 + 11 = 120 + 11 = 131 minutes.
