Answer:
Area of circle: 1662.57 cm
Circumference of circle: 144.57 cm
Step-by-step explanation:
Formula of area of circle:
pi x r2 or radius x radius
So, it's 22/7 x 23 x 23 = 1662.571429
Formula of circumference of circle:
2 x pi x radius OR
pi x diameter
Let's use the second method, to find diameter it is radius x 2 = 46
So,
46 x 22/7 = 144.5714286

Evaluate: C(14, 10)
no pic just answer it
Given:
The combination C(14,10).
To find:
The value of the given combination.
Solution:
We know that,
[tex]C(n,r)=\dfrac{n!}{r!(n-r)!}[/tex]
Using this formula, we get
[tex]C(14,10)=\dfrac{14!}{10!(14-10)!}[/tex]
[tex]C(14,10)=\dfrac{14\times 13\times 12\times 11\times 10!}{10!(4)!}[/tex]
[tex]C(14,10)=\dfrac{14\times 13\times 12\times 11}{4\times 3\times 2\times 1}[/tex]
[tex]C(14,10)=7\times 13\times 11[/tex]
[tex]C(14,10)=1001[/tex]
Therefore, the value of C(14,10) is 1001 and the correct option is B.
The equivalent expression of "[tex]C(14,10)[/tex]" is "1001".
Equivalent expression:using formula:
[tex]\to ^n C_r=\frac{n!}{r!(n-r)!}[/tex]
putting the given value into the above formula:
[tex]\to ^{14} C_{10}=\frac{14!}{10!(14-10)!}[/tex]
[tex]=\frac{14 \times 13 \times 12 \times 11 \times 10! }{10! \times 4 \times 3 \times 2 \times 1}\\\\=\frac{14 \times 13 \times 12 \times 11 }{ 4 \times 3 \times 2 \times 1}\\\\={7 \times 13 \times 11 }{}\\\\=1001[/tex]
Therefore, the final answer is "1001".

Step-by-step explanation:
The distance in miles that some students live from school is show in the histogram which stamen about the data in the histogram is true
Answer:
D). The distribution of the data is symmetrical, so the mean and median are within the "2.1-3 mile" category.
Step-by-step explanation:
The last statement i.e. 'The distribution..."2.1-3 mile" category' correctly asserts a true claim regarding the data provided in the given histogram. It aptly states that the dissemination of the data is uniform(2, 4, 5, 4, 2(no. of students) live between the distance of 0.1 to 5 miles from the school) and this causes both the mean, as well as, the median of the distribution to fall in the category between '2.1 to 3 mile.' Thus, option D is the correct answer.
Duncan is running to raise awareness and money for cancer. He finds 2 people who have pledged to
donate money based on the distance he runs. His neighbor says he will donate $0.25 for every 40 feet
Duncan runs. His aunt also says that she will donate $12 for every mile he runs. If Duncan runs a total of
7 miles during the cancer awareness run, how much money will he have raised based on these two
donations?
Answer:
$1008
Step-by-step explanation:
12 x 7 = $84 his aunt gives him.
1 mile = 5,280 feet
5,280 x 7 = 36,960 feet he ran.
5,280 ÷ 40 = 132 for every mile he runs
132 x 7 = $924 from his neighbor.
924 + 84 = 1,008
what is the value of z?
Answer:
3 (z = 35)
Step-by-step explanation:
(22 + 19) + 104 + z = 180° => triangle sum theorem
41 + 104 + z = 180
145 + z = 180
145 + z - 145 = 180 - 145
z = 35

The expression is given as;
[tex]\frac{9}{5x}[/tex]
Q2 The product of a sum and difference of x and y
Sum of x and y = x + y
Difference of x and y = x - y
The expression is given as;
(x + y) * ( x -y)

The dimensions of a box are (x+3),(3x-4),(5x+1). What is the volume of the box? 9x 9x^3 15x^3+28x^2-55x-12
Answer:
15x^3+28x^2-55x-12
Step-by-step explanation:
Dimensions of the box are (x+3), (3x-4), and (5x+1). Let these be length, width and height of the box.
assuming the box is cuboidal
Therefore, volume of the box = Length× width× height
⇒volume of the box = (x+3)×(3x-4)×(5x+1)
now, (x+3)×(3x-4) = (3x^2+5x-12)
Now, volume of the box = (3x^2+5x-12)×(5x+1)
= 15x^3+28x^2-55x-12

0.4x - 1.2 = 0.15x + 0.8 ?????????
Answer:
x = 8
Step-by-step explanation:
0.4x - 1.2 = 0.15x + 0.8
0.4x - 1.2 + 1.2 = 0.4x
0.15x + 0.8 + 1.2 = 0.15x + 2
0.4x = 0.15x + 2
0.4x - 0.15x = 0.25x
0.15x + 2 - 0.15x = 2
0.25x = 2
0.25x / 0.25 = x
2 / 0.25 = 8
x = 8

Round the following real number to the nearest hundredth: 67.498
Answer:
67.50
Step-by-step explanation:
Answer:
67.5The hundredth is always the second number after the decimal point (to the right).
So, when rounding to that number look at the number on the right of it, which in this case is 9.
Then, if the number is 5 to 9, round up, but if it is 0 to 4, round down.
In this case, the number above 0.49 is 0.5.

Ben put $6,500 into a savings account that earns 2.5% interest each year. How much interest will he earn after 6 years in the savings account?
Answer:
$1,038
Step-by-step explanation:
the equation for annual compound interest is y=p(1±r)^t, where p is the principal (starting amount), r is the rate (as a decimal), and t is the number of years (time).
2.5% as a decimal is 0.025
We will add that to 1, because when we earn interest, we are gaining money.
So we will substitute our given numbers into the equation:
y=6500(1.025)^6
solve:
y=$7,5638 (rounded)
That's the total amount he earned (principal + interest). To find out how much interest he earned over those 6 years, subtract our new amount from our starting amount
75638-6500
$1,038
So he made $1,038 in interest

Angle DEF is similar to angle JKL.Find the length of JL and KL? First triangle DF 12.4cm DE 4cm EF 9cm other triangle JK 3cm JL ? KL ?
Answer:
KL = 6.75cm
JL = 9.3cm
Step-by-step explanation:
SInce Angle DEF is similar to angle JKL.
Then;
DE/EF = JK/KL
Given
DE = 4cm
JK = 3cm
EF = 9cm
Substitute
4/9 = 3/KL
4KL = 27
KL = 27/4
KL = 6.75cm
Similarly
DF/EF = JL/KL
12.4cm/9 = JL/6.75
9JL = 12.4 * 6.75
9JL = 83.7
JL = 83.7/9
JL = 9.3cm
