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!

4) The length of a rectangle is 7 inches more than the width. The perimeter of the rectangle
is 178 inches. Find the width of the rectangle.
Answer:
41 inches
please mark brainliest
Step-by-step explanation:
l= 7+w
perimeter = 2(l+w) =2(7+w +w)= 2(7+2w)= 14+ 4w
178= 14+4w
4w =178-14= 164

Answer:
GH = 15
Step-by-step explanation:
14. BC = 19
GH = 9x - 3
FE = 5x + 1
Given that GH is the midsegment of the trapezoid, therefore:
GH = (BC + FE)/2
Plug in the values
9x - 3 = (19 + 5x + 1)/2
9x - 3 = (20 + 5x)/2
Multiply both sides by 2
2(9x - 3) = 20 + 5x
18x - 6 = 20 + 5x
18x - 5x = 20 + 6
13x = 26
Divide both sides by 13
x = 2
✔️GH = 9x - 3
Plug in the value of x
GH = 9(2) - 3 = 18 - 3
GH = 15

out of 75/6 is 72%. (Write as a fraction in simplest form.)
Answer:22%
Step-by-step explanation:
The simplest form of the total of 75/6 would be 432 / 7500.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100. Suppose the value of which a thing is expressed in percentage is "a' Suppose the percent that considered thing is of "a" is b%
Then the percent; per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Given that out of 75/6 is 72%.
Therefore, it will be written as;
x of 75/6 = 72%.
We need to find the value of total x.
x of 75/6 = 72%.
x × 75/6 = 72%
x × 75/6 = 72/100
Cross multiplication;
x = 72/100 × 6/75
x = 432 / 7500
x = 0.0576
Hence, the simplest form of the total of 75/6 would be 432 / 7500.

What do you need help with?
Step-by-step explanation:
The measure of Angle D is
degrees.
O=41 degrees
Answer:
49°
Step-by-step explanation:
O=41° and G=90° (because it is a right angle). The sum of the interior angles of a triangle is 180°. So, add the known angles, 41°+90°=131°. Since the sum of all three angles needs to be 180°, subtract the known angles from the total, 180°-131°=49°, to find the unknown angle.
The angle D in triangle OGD measures 49 degrees.
To find the measure of angle D in triangle OGD, we can use the fact that the sum of the angles in a triangle is always 180 degrees.
Given that angle O is 41 degrees and angle G is 90 degrees, we can substitute these values into the equation:
Angle O + Angle G + Angle D = 180
41 + 90 + Angle D = 180
131 + Angle D = 180
Now, we can solve for angle D by subtracting 131 from both sides:
Angle D = 180 - 131
Angle D = 49
Therefore, angle D in triangle OGD measures 49 degrees.

Write an equation where a number is added to a variable, and a solution is -8.
Write an equation where a number is multiplied by a variable, and a solution is - 4/5 (negative four fifths)
also dont answer if you don't know
Let the variable be x
A number isn’t given so pick any number.
Let’s use 10
Set up the equation to get:
X + 10 = -8
Solve for the variable by subtracting 10 from both sides:
X = -18
Let the variable be y and pick any number, let’s use the number 2.
Equation: 2 x y = 4/5
Solve for y by dividing both sides by 2:
Y = 2/5

Find the slope and y-intercept of equation y= 10x + 18
Answer:
slope is 10
y-intercept is 18
Step-by-step explanation:
The slope and y-intercept in y = 10x + 18 are 10 and 18 respectively.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given a line in slope-intercept form which is y = 10x + 18.
We know in y = mx + b, slope = m, and y-intercept = b.
∴ In y = 10x + 18.
Slope = 10 and y-intercept = 18.

Answer:
B) 81°
Step-by-step explanation:
∡1 ≅ ∡5 because they are corresponding angles
∡5 ≅ ∡7 because they are vertical angles
therefore, ∡1 ≅ ∡7
since the angles are equal we can create the following equation:
3x + 18 = 2x + 39
x + 18 = 39
x = 21
∡7 = 2(21) + 39
∡7 = 42 + 39
∡7 = 81
