Answer:
21.42 inStep-by-step explanation:
It will have a perimeter of:
r + r + 1/4C =2r + 1/2πr = 12 + 1/2*6*3.14 = 12 + 9.42 = 21.42 insolve 10x-10g(4x-2)=1
Answer:
Below
Step-by-step explanation:
x=[tex]\frac{1-20g}{10(1-4g)}[/tex]
Answer:
using BODMAS=(4x-2)=(2x)
10x-10g(2x)=
10x=10+(2x)=
10x=20x
divide both sides by 10
10x/10=20x/10
x=20/10
x=2

What is a rectangle?A rectangle is one of the types of quadrilaterals in which all four angles are right angles or equal to 90 degrees. It is four-sided polygon in which the opposite sides are parallel and equal to each other.
For the given situation,
The diagram shows the polygon.
Let us consider the polygon as two rectangles as opposite sides are parallel and all the angles are right angle as shown below.
The rectangle ABCD has the dimensions length is 10 cm and breadth is 27 cm.
The rectangle DEFG has the dimensions length is 14 cm and breadth is 9 cm.
Thus the area of the polygon is the sum of areas of rectangle ABCD and DEFG.
The formula of area of rectangle, [tex]A =( length)(breadth)[/tex]
Then total area of the shape is
⇒ [tex](27)(10)+(14)(9)[/tex]
⇒ [tex]270+126[/tex]
⇒ [tex]396[/tex]
Hence we can conclude that the area of the shape is 396 square cm.

The courtyard of an apartment complex is represented by the vertices T(4, 1), U(30, 11), and V(17, 36). Each unit represents 1 meter. A bench is located at the centroid of the courtyard. Which ordered pair gives the coordinates of the centroid?
Answer:
[tex](x,y) = (17,16)[/tex]
Step-by-step explanation:
Given
[tex]T(x_1,y_1) = (4, 1)[/tex]
[tex]U(x_2,y_2) = (30, 11)[/tex]
[tex]V(x_3,y_3) = (17, 36)[/tex]
Required
Determine the coordinates of the centroid
The coordinate is calculated as:
[tex](x,y) = (\frac{1}{3}(x_1+x_2+x_3),\frac{1}{3}(y_1+y_2+y_3))[/tex]
Substitute values for x's and y's
[tex](x,y) = (\frac{1}{3}(4+30+17),\frac{1}{3}(1+11+36))[/tex]
[tex](x,y) = (\frac{1}{3}(51),\frac{1}{3}(48))[/tex]
[tex](x,y) = (\frac{51}{3},\frac{48}{3})[/tex]
[tex](x,y) = (17,16)[/tex]
Hence, the coordinates of the centroid is (17,16)
2. What is the equation of the line with a y-intercept of (0,8) and a slope of
-2? *
A. y = 8x + 2
B. y = -8x-2
C. y = 2x + 8
D. y = -2x +8
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2 and c = 8, then
y = - 2x + 8 → C

The percentage decrease in basketball participation from 2013-2014 to 2014-2015 is 0.35%.
What is the Percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.
As per the given information in the question,
Number of basketball participants in 2013-2014 = 974,398
Number of basketball participants in 2014-2015 = 970,983
Then, the percentage decrease in the participants,
% decrease = (974,398 - 970,983)/ 974,398 × 100
% decrease = 0.35%.

There were 1 200 people in a
village. If 40% of them were adults.
how many children were there?
A. 480
B. 720
C.800
D 1 160
Answer:
A. 480
Step-by-step explanation:
ok so first you multiply 1200 by 40 percent
we gonna change 40 percent to a decimal which will be 0.40
then multiply which will get 480
Answer:
720 children
Step-by-step explanation:
40% were adults
So 60% were children
60% of 1200 is 720 children (0.60 x 1200)
A card has p meters of lace edging wound on it. Nerys buys n lengths of edging, each x cm long. If Q meters of edging are left on the card, find a formula for Q in terms of P, n and x
Answer:
Q = P - n(x/100)
Step-by-step explanation:
P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.
So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;
Q = P - n(x/100)
The air force reports that the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches. Part A: A male pilot whose height is 74.2 inches is at what percentile? Mathematically explain your reasoning and justify your work. (5 points) Part B: Air force fighter jets can accommodate heights of soldiers between 70 inches and 78 inches without compromising safety. Anyone with a height outside that interval cannot fly the fighter jets. Describe what this interval looks like if displayed visually. What percent of male pilots are unable to fly according to this standard? Show your work and mathematically justify your reasoning. (5 points)
Answer:
Step-by-step explanation:
Given that X - the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches.
Height of male pilot = 74.2 inches
We have to find the percentile
X = 74.2
Corresponding Z score = 74.2-72.6 = 1.6
P(X<174.2) = P(Z<1.6) = 0.5-0.4452=0.0548=5.48%
i.e. only 5% are below him in height.
Thus the malepilot is in 5th percentile.

Kate had a sum of money,she spent 1/8 of the money on a skirt and the remaining amount on a handbag,the skirt cost $16,how much money did kate have at first?
Answer:
$18.28
Step-by-step explanation:
Step one:
given data
Kate had a sum of money,she spent 1/8 of the money on a skirt and the remaining amount on a handbag
let the total money be x
so mathematically
x-1/8*x= 16
solve for x
x-x/8= 16
8x-x/8= 16
7x/8=16
cross multiply
7x= 8*16
7x=128
divide both sides by 7
x=128/7
x=$18.28
