Answer:
1.68 Meters
Step-by-step explanation:
Hello I think I can help with this.
Well basically the way it is represented as a fraction is a portion of a whole like a percent :
For example : 21%
So basically we just need to turn this into a decimal and then add to find how long the books would be together.
How I would go about doing this is first looking at the 21/100 and remember that in decimals 1.00 is a whole just like the 100. So in this case the 100 in 21/100 would be 1.00.
So knowing this, we can take the 21 in 21/100 and say that 0.21/1.00 is equal to 21/100 because the 21 is representing how much of a meter the books are while 100 is the whole meter.
Now, we know we have eight books and each are .21 long. So we can do :
.21 x 8
=
1.68
While this is the answer we can write it in two ways. Either in fraction form like it started or in decimal form which I think is how they want you to write the answer.
For fraction :
168/100 Meters
We can simplify this :
1 68/100 Meters
EDIT :
We can simplify this even more :
Lets divide both sides by 2 :
34/50
AND we can do it again :
So divide by 2 on both sides :
17/25
And don't forget to add the 1 back into it :
1 17/25
And for the decimal form it is just what we found already :
1.68 Meters
I hope this helps!

Standardized tests: In a particular year, the mean score on the ACT test was 19.3 and the standard deviation was 5.3. The mean score on the SAT mathematics test was 532 and the standard deviation was 128. The distributions of both scores were approximately bell-shaped. Round the answers to at least two decimal places. Part: 0/4 Part 1 of 4 (a) Find the z-score for an ACT score of 26. The Z-score for an ACT score of 26 is
Answer:
1.26
Step-by-step explanation:
Given that:
For ACT:
Mean score, m = 19.3
Standard deviation, s = 5.3
Zscore for ACT score of 26;
Using the Zscore formula :
(x - mean) / standard deviation
x = 26
Zscore :
(26 - 19.3) / 5.3
= 6.7 / 5.3
= 1.2641509
= 1.26
What is the value of the expression 13.5- 6.48
13.5-6.48=7.02
Step-by-step explanation:
You just pine them up and subtract. So the decimal points would be one under another. The 6 would be under the 3. Lastly the 4 would be under the 5 and the 8 would be beside the 4. Then you just subtract...or use a calculator
What is the value of X in this question?? I need help please!
Answer:
The value of x would be 23
Step-by-step explanation:
You must first find the angles of triangle CDE. So to find angle C you must know that a straight line is equal to 180 degrees, 180-117=63 So angle C would be 63 degrees. Angle D is congruent to Angle B so Angle D would equal 24 Degrees. Then to find the angle of Angle E simply subtract 87 from 180 (You Get 87 From Adding 24 and 63), 180-87=93. Know that you know that Angle E is 93 Degrees set up the equation, 4x+1 = 93 SOLVE.
4x+1=93
4x = 92
x = 23.
4. MARBLES Virginia's
mother gave her marbles for
her birthday. Virginia lost 13
of them. If she has 24 marbles
left, write and solve an
equation to find how many her
mother gave her.
Answer:
37
Step-by-step explanation:
If she has 24 left, and lost 13, you add 13 and 24 to find the original amount.
Virginia's mother gave her 37 marbles for her birthday.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Virginia's mother gave her marbles for her birthday.
Let number of marbles = x
Here, Virginia lost 13 of them and she has 24 marbles left.
So, We get;
⇒ x - 13 = 24
Solve for x;
⇒ x = 24 + 13
⇒ x = 37
Thus, Virginia's mother gave her 37 marbles for her birthday.

Answer:
(x, y) = (3, 12)
Step-by-step explanation:
Using the given variable definitions, we can write the equations ...
y = x + 9
2(x +y) = 30
__
Solving the second equation for y, we have ...
y = 15 -x
Substituting this into the first equation gives ...
15 -x = x +9
6 = 2x . . . . . . . . . add x-9
3 = x . . . . . . . . . . divide by 2
y = 3+9 = 12 . . . . substitute into the first equation
The numbers are (x, y) = (3, 12).
Which statement about the angles in the figure is true?
Helppp
9514 1404 393
Answer:
m∠1 +m∠8 = 90°
Step-by-step explanation:
There is no necessary sum relation between angles 3 and 5 or angles 7 and 10. The only thing you can say about those angle pairs is ...
∠3 + 90° = ∠5
∠10 +90° = ∠7
Angles 8 and 9 are congruent, so don't have any necessary sum.
Angle 1 is congruent with angle 3, which is complementary to angle 8, so we must have ...
m∠1 +m∠8 = 90°

Jordan invests £2100 into his bank account.
He receives 5.1% per year simple interest.
How much will Jordan have after 2 years?
Give your answer to the nearest penny where appropriate.
Answer:
£4414.20
Step-by-step explanation:
Find out how much is 1% of the money invested in his bank account.
100% = 2100
1% = 2100 ÷ 100 = 21
Find out 5.1% which is his interest that he receives every year.
5.1% = 21 x 5.1 = 107.1
Find out how much he receives including interest every year.
2100 + 107.1 = 2207.1
Find out how much he will have after 2 years.
2207.1 x 2 = 4414.2
You do not need to estimate as there isn't an estimated for nearest penny as it has been estimated for you.
