Part B
What is the length of missing side?
PLEASE HELP
Answers
Answer: the scale factor is 1/2
And the missing side is 5.5
Step-by-step explanation:
The larger triangle is twice the smaller triangle
The scale factor is 1/2 and the length of the missings side is 5.5 after using the concept of the scale factor.
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
It is given that:
The two rectangles are shown in the picture:
Part A what is the scale factor used when going from the larger rectangle to the smaller one?
The scale factor = 8/16 = 1/2
The length of the missings side = 1/2(11) = 5.5
Thus, the scale factor is 1/2 and the length of the missings side is 5.5 after using the concept of the scale factor.

Find the sum. Write your answer in simplest form. 3/7 + 2/3
Answers
Answer:
1 2/21
Step-by-step explanation:
We start out with:
3/7 + 2/3
In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:
3/21 + 2/21
But what about the numerators? You do the same thing as before (multiplying by the other's denominator). Now we have:
9/21 + 14/21
We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:
1 2/21!

An image of a horizontal number line is shown with labels from negative 2 to positive 8. An arrow begins at 0 and ends at 8. Another arrow begins at 8 and ends at 1.
Answers
Answer:
[tex]7 + (-8)[/tex]
Step-by-step explanation:
Given
[tex]7 - 8[/tex]
(a): Write as additive inverse.
An additive inverse is of the form a + (-b)
In this case:
[tex]a = 7[/tex]
[tex]b = -8[/tex]
So, the expression can be represented as:
[tex]7 + (-8)[/tex]
(b): Number line representation
When the expression in (a) is solved.
The result is:
[tex]7 - 8 = 7 + (-8) = -1[/tex]
This means that the number line must accommodate 7 and -1.
Having said that, options (b) and (c) are out because their range is 0 to 15 and this excludes -1.
Option (d) is a wrong representation of [tex]7 - 8[/tex]
Hence, (a) is correct
What is the solution to the inequality described below?
Four-fifths of a number is greater than five plus that number.
Answers
Answer:
x < -25
Step-by-step explanation:
Let the number be x.
4/5 * x > 5 + x
4/5 x - x > 5
-1/5 x > 5
x < -25
The solution to the inequality described is x < -25
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.
Given that the inequality; Four-fifths of a number is greater than five plus that number.
Let the number be x.
4/5 x > 5 + x
4/5 x - x > 5
-1/5 x > 5
x < -25
Therefore, The solution to the inequality described is x < -25

804 736 659 489 777 623 597 524 228
For the same data, what value corresponds to the 40th percentile
Answers
Answer:
a. 228- 6th, 489- 17th, 524- 28th, 597- 39th, 623- 50th, 659- 61th, 736- 72th, 777- 83th, 804- 94th
b. 597
Step-by-step explanation:
arrange the data:
228, 489, 524, 597, 623, 659, 736, 777, 804
a. percentile = ((number of items below position + 0.5)/ number of items ) 100
for 228 = (0+0.5/ 9) 100 = 6th
for 489 = (1+0.5/ 9) 100 = 17th
for 524 = (2+0.5/ 9) 100 = 28th
for 597 = (3+0.5/ 9) 100 = 39th
for 623 = (4+0.5/ 9) 100 = 50th
for 659 = (5+0.5/ 9) 100 = 61th
for 736 = (6+0.5/ 9) 100 = 72th
for 777 = (7+0.5/ 9) 100 = 83th
for 804 = (8+0.5/ 9) 100 = 94th
b. The corresponding value for the 40th = number of item( percentile)/ 100
= 9( 40) / 100 = 3.6 approximately 4th which is 597

Pentagon PQRST is a scale drawing of pentagon ABCDE.
All side lengths of pentagon ABCDE are 5 except side BC is 6. All side lengths of pentagon PQRST are 2.5 except side QR is labeled x.
What is the value of x?
Answers
Answer:
x = 3
Step-by-step explanation:
Pentagon PQRST is a scale drawing of pentagon ABCDE.
Therefore, scale factor = [tex]\frac{\text{One side of pentagon PQRST}}{\text{One side of pentagon ABCDE}}[/tex]
= [tex]\frac{QR}{BC}[/tex] Or [tex]\frac{SR}{DC}[/tex]
Ratio of the sides will be same,
[tex]\frac{QR}{BC}=\frac{SR}{DC}[/tex]
[tex]\frac{x}{6}=\frac{2.5}{5}[/tex]
x = [tex]\frac{6}{2}[/tex] ≈ 3
Therefore, x = 3 will be the answer.

The equations which have slope 1/4:
ii. (y - 3.5) = 0.25(x - 2.75)
iii. 5x - 20y = 32
What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
The slope-intercept form of a linear equation is y = mx + b, where m is the slope.
I. y = x - 5 is in slope-intercept form, so we can see that its slope is 1.
II. (y - 3.5) = 0.25(x - 2.75) can be rewritten in slope-intercept form as y = 0.25x + 2.1875. Therefore, its slope is 0.25 or 1/4.
III. 5x - 20y = 32 can be rewritten in slope-intercept form as y = (1/4)x - (4/5). Therefore, its slope is 1/4.
IV. 5x + 20y = 32 can be rewritten in slope-intercept form as y = (-1/4)x + (4/5). Therefore, its slope is -1/4.
So, only equations II, and III have a slope of 1/4.
