find the distance of a cord 8cm from the centre of a circle of a radius 5 cm
Answer:
d = 3 cm
Step-by-step explanation:
Given that,
The distance of a cord, c = 8 cm
The radius of the circle, r = 5 cm
Half of the cord = 4 cm
We need to find the distance of a cord from the centre of the circle. We can find it using Pythagoras theorem,
[tex]5^2=d^2+4^2\\\\d^2=25-16\\\\d=3\ cm[/tex]
So, the required distance is 3 cm.

Given:
The frequency distribution table.
To find:
The mean average score on a test.
Solution:
The frequency distribution table is
[tex]Marks (x_i)[/tex] [tex]Frequency(f_i)[/tex] [tex]f_ix_i[/tex]
x a xa
y b yb
z c zc
Sum a+b+c xa+yb+zc
Now, the mean average score on the test is
[tex]Mean=\dfrac{\sum f_ix_i}{\sum f_i}[/tex]
[tex]Mean=\dfrac{xa+yb+zc}{a+b+c}[/tex]
Therefore, the mean average score on the test is [tex]\dfrac{xa+yb+zc}{a+b+c}[/tex].

Find the LCM.
11, 13
STEP 1: Define the LCM (least common multiple).
The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of all the numbers.
The LCM can be found by first writing each number as a product of prime factors.
The LCM must contain all the prime factors of each number.
STEP 2: Determine the prime factorization of each number.
Determine the prime factorization of 11.
11 =
Determine the prime factorization of 13.
13 =
STEP 3: Multiply all of the prime factors.
11 ×
=
LCM =
Answer:
143...is the lcm...
Step-by-step explanation:
lcm (11; 13) = 143: least common multiple, calculated. Numbers have no common prime factors: 143 = 11 × 13...................

Sandra wrote the sequence shown:
7, 14, 25, 40, 59
Complete each of the 2 activities for this Task.
Activity 1 of 2
What explicit expression can be used to find the nth term of this sequence?
Answer:
2n^2 + n + 4.
Step-by-step explanation:
7, 14, 25, 40, 59
The differences are 7, 11, 15, 19 which is arithmetic sequence so the given sequence is quadratic.
Compile a table:
n 1 2 3 4 5
term 7 14 25 40 59
Diff: 7 11 15 19
Diff: 4 4 4 - this indicates that first part is 2n^2.
2n^2 2 8 18 32 50
term-2n^2 5 6 7 8 9
- the nth term for the last sequence is 5+ (n - 1)d =
= 5 + (n - 1)* 1
= n + 4.
So nth term for the original sequence is 2n^2 + n + 4.

Haley made 88% on a history test. The
test had 50 questions of equal point value.
How many questions did Haley miss?
Answer:
She missed 6 questions.
Step-by-step explanation:
88% can be written as (88/100) or as 0.88.
You can set this as a ratio problem which is,
88/100 = correct/50
correct = (88/100)*50 (multiply both sides by 50)
correct = 44
So, 50 (total questions) - 44 = 6 incorrect questions

(5x4+5x3-17x2+6x)-(3x4+6x3-7x2-12)/x+2
Please show your work
Answer:
6x^2+3x-4/x
Step-by-step explanation:
first multiply to get (20+5x3-17x2+6x)-3x4+6x3-7x2-12/x+2
then remove the two opposites that add up to zero to get (20+15-34+6x)-6x3-7x2/x+2
then remove unnecessarry parentheses to get 1+6x-18-14/x+2 and then calculate to get 3+6x-4/x
then write all of the numerators above the common denominator to get 3x+6x^2-4/x and reorder the terms to get your solution which is 6x^2+3x-4/x

Mr. And Mrs. Jenkins wanted to make a down payment of $25,000 on a house. If the house costs $125,000, what percent is this?
Answer:
20%
Step-by-step explanation:
Mr. And Mrs. Jenkins wanted to make a down payment of $25,000 on a house. If the house costs $125,000, what percent is this?
The Percentage of the down payment is given as:
Down payment/Cost of the house × 100
Down payment = $25,000
Cost of the house = $125,000
$25,000/$125,000 × 100
= 20%
The percentage is 20%

Answer:
28 in
Step-by-step explanation:
Given is an isosceles triangle.
In an isosceles triangle, measure of the sides opposite to the equal angles are equal.
Therefore,
3x + 2 = x + 6
3x - x = 6 - 2
2x = 4
x = 4/2
x = 2 in
x + 6 = 2 + 6 = 8
Perimeter of the triangle
= 8 + 8 + 12
= 28 in
