round 21.24833 to three decimal places
Answer:
21.248
Step-by-step explanation:
The required value of decimal value 21.24833 to three decimal points is 21.248.
Given that,
21.24833, to round this number to 3 decimal places.
In mathematics, it deals with numbers of operations according to the statements.
Recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.
In the question, a decimal value is given, 21.2488, and asked to round this off to 3 decimal places.
When rounding off the number, we check the preceding value neared to which zero either to 0 or 10. if it is near 0 the value before is round off value and the preceding value is near 10 then the value before the proceeding value is increased by 1.
In our case, the value after the third decimal is 3 which is near 0 so nothing will change and the value terminates as it is after 3 decimal points i.e 21.248.
Thus, the required value of decimal value 21.24833 to three decimal points is 21.248.

A sports shop got a skateboard that cost them $80. In order to make a
profit, they decide to add a 37.5% markup. What is the retail price of the
skateboard?
The retail price of the skateboard = [tex] \color{hotpink}\boxed{\bold{\tt\bold{\$110}}}[/tex]
○=> Steps to derive correct answer :Given :
▪︎Cost price of a skateboard in a sports shop = $80
▪︎Percentage of markup in the price of the skateboard = 37.5%
Which means :
The retail price of the skateboard :
= Intial price of skateboard + 37.5% of it's initial price
[tex] = \tt80 + 37.5\% \: of \: 80[/tex]
[tex] =\tt 80 + \frac{37.5}{100} \times 80[/tex]
[tex] =\tt 80 + \frac{37.5 \times 80}{100} [/tex]
[tex] = \tt80 + \frac{3000}{100} [/tex]
[tex] =\tt 80 + 30[/tex]
[tex]\color{plum} = \tt\bold{\$110}[/tex]
Therefore, the retail price of the skateboard = $110

Answer:
65 square units
Step-by-step explanation:
The area of a triangle is: height times base divided by two.
So the area of one of the triangles is 10 square units.
multiply this times 4 to get the total area of the triangles
then add the area of the square which is 5 times 5
25 plus 40 = 65 square units

£399 is shared between ann,bill, chloe and dave. The ratio of the amount ann gets to bill gets is 2:9 chloe and dave get 2.5 times the amount ann gets.
Work out how much money bill gets
Answer:Bill gets £171
Step-by-step explanation:
Total Money shared = £399
The ratio of the amount Ann gets to bill gets is 2:9 Chloe and Dave get 2.5 times the amount Ann gets can be written as
Ann : Bill : Chloe : Dave
2 : 9 : 2.5 x Ann : 2.5 x Ann
Let the amount of money
Ann gets be x
so that Bill gets 4.5x
Chloe = 2.5x
Dave = 2.5x
So that the expression to calculate each amount gooten will be
x + 4.5x + 2.5x + 2.5x = 399
10.5x = 399
x = 399/10.5
x=38
Therefore, Ann gets = £38
Bill gets =4.5 x= 4.5 x £38 = £171
Chloe gets=2.5x =2.5 x £38 = £95
Dave gets=2.5x =2.5 x £38 = £95

1st one x=245°
2nd one x= 250
Step-by-step explanation:
hope its correct
hope u find it helpful
Answer:
x = 245 and x = 20
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
Sum the interior angles and equate to 540
25 + 112 + 100 + 58 + x = 540
295 + x = 540 ( subtract 295 from both sides )
x = 245
---------------------------------------------------------------
5x + 2 + 3x + 5 + 8x + 8 + 4x + 15 + 5x + 10 = 540
25x + 40 = 540 ( subtract 40 from both sides )
25x = 500 ( divide both sides by 25 )
x = 20

If a1 = 4 and an =
- 4 an–1 then find the value of a6.
Answer: -4096
Step-by-step explanation:
The 6th term of the geometric sequence is; -4096.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given as:
[tex]a_n = a_1q^{n-1}[/tex]
In which a1 is the first term.
For this problem, we have :
The first term is a1 = 4 and an =- 4 an–1 .
Therefore, the common ratio is q = -4.
Now the 6th term of the sequence is found as :
[tex]a_6 = 4(-4)^{5[/tex]
a_6 = - 4096

Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .
