Answer: X=50
Step-by-step explanation:
Data: 4 less than half of a number(x) is 21
Step one, make an equation
(x/2)-4=21
The reason for this is that since we know that 21 is 4 less than half the number(x) we can assume that dividing x by 2 will get half of it and by subtracting 4, we can get 21 which why it equals 21. By having it in an equation, it makes it easier to solve.
Step two, Start isolating x by adding 4 on both sides
(x/2)-4+4=21+4=(x/2)=25
The reason for this is that we have to find what x is which is done by isolating it. So if you add 4, you get rid of the -4 which helps isolate x and what you do to one side, you do to the other so you add 4 to 21 as well
Step three, multiply by 2 on both sides
(x/2)x2=25x2=X=50
The reason for this is that /2 is next to x so to isolate you have to get rid of it by multiplying by 2 and since what you do to one side you do to the other, you multiply 25 by 2 to get 50.
Answer: X=50

3) Mary deposits £10000 in an account which pays 5.6% compound
interest per year.
How much will Mary have in her account after 5 years?
Answer:
FV= £13,131.66
Step-by-step explanation:
Giving the following information:
Initial Investment (PV)= £10,000
Interest rate (i)= 5.6%
Number of periods (n)= 5 years
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1 + i)^n
FV= 10,000*(1.056^5)
FV= £13,131.66
Mike and Andre want to equally share 46 feet of rope. What amount of rope should each person get? A. 13 B. 36 C. 12 D. 16
Answer:
23 feet
Step-by-step explanation:
According to the scenario, computation of the given data are s follows,
Total rope = 46 feet
Number of person = 2
So, we can calculate the amount of rope each person get by using following formula,
Each person quantity = Total rope ÷ Number of person
By putting the value in the formula, we get
Each person quantity = 46 feet ÷ 2
= 23 feet
Hence, each person gets 23 feet of rope.

3) Six teams are playing in a baseball tournament. In how many ways can the teams be crowned champion and
runner-up?
Answer:
15ways
Step-by-step explanation:
This question bothers combination
Combination has to do with selection
Given
Total number of teams = 6
champion and runner up = 2
number of ways is expressed as 6C2
6C2 = 6!/(6-2)!2!
6C2 = 6!/4!2!
6C2 = 6*5*4!/4!*2
6c2 = 30/2
6C2 = 15
Hence the number of ways they can be selected is 15ways
Please I need help ASAP! I don't know any of the answers. For the second question, I accidentally clicked on it.
The function f is given by f(x)= (x-2) (x+4) . Without using graphing technology, answer the following questions. (graph included)
1) What are the x-intercepts of the graph representing f?
2) What are the x- and y-coordinates of the vertex of the graph?
please help!!
Answer:
x-intercepts = -4 and 2
vertex (-1, -9)
Step-by-step explanation:
To find the x-intercepts ie roots
set the equation to 0
(x - 2) (x + 4) = 0
From the zero product rule
x - 2 = 0
x = 2
x + 4 = 0
x = -4
x-intercepts = -4 and 2
--------------------------
The x coordinate of the vertex is the midpoint of the roots
x = (-4 + 2)/2
x = -1
Plug x = -1 into the function
y = (-1 - 2)(-1 + 4)
y = -3 * 3
y = -9
vertex (-1, -9)

what's the absolute value of 4.5 ?
Answer:
the absolute value or 4.5 is 4.5
Step-by-step explanation:
Answer:
4.5
Step-by-step explanation:
absolute value: the distance away from zero, it will always be positive because distance can't be negative.
thus, the absolute value of 4.5 = the distance of 4.5 to zero, which is 4.5
|4.5| = 4.5

Charles says that the number line shows all the values that make the inequality
n2-1 true. Do you agree with Charles? Explain.
4 5
-3 -2 -1
0 1 2 3
Answer:
no
Step-by-step explanation:
n ≥ - 1
The inequality states that n is greater than or equal to - 1
To show the equal part on the number line the point at - 1 must be a solid circle, not an open one
No, the given number line does not represent the number line shown by Charles.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
The inequality is given by Charles,
n ≥ -1
But in the given number line, the value of n is not defined as 1, but Charles inequality consists of the value of n = 1, so the given number line does not represent the number line shown by Charles.
Thus, the given number line does not represent the number line shown by Charles.

the sum of two digit number and the number obtained by reversing its digit is 154 if the digit differ from 4 find the number
Answer:
The number is either 95 or 59
Step-by-step explanation:
The two digit number would be;
(10a + b)
The reversal will be (10b + a)
The sum of the two is 154
(10a + b ) + (10b + a) = 154
11a + 11b = 154
11(a + b) = 154
a + b = 14 ••••••••(i)
The difference between the two digits is 4
Let’s have this as;
a - b = 4 ••••(ii)
from ii;
a = 4 + b
Substitute this into equation i
4 + b + b = 14
2b = 14-4
2b = 10
b = 10/2
b = 5
Recall;
a = b + 4
a = 5 + 4
a = 9
So we have the number as 95 or 59
