Answer:
#5Given vertices:
(8, -5) and (8, 7)These have same x-coordinate, so when connected form a vertical segment.
The length of the segment is:
7 - (-5) = 12 unitsThe area of the rectangle is 72 square units, so the horizontal segment has the length of:
72/12 = 6 unitsPossible location of the remaining vertices (to the left from the given):
(8 - 6, -5) = (2, -5)and
(8 - 6, 7) = (2, 7)#6Similarly to previous exercise:
(5, -8) and (5, 4) given with the area of 48 square unitsThe distance between the given vertices:
4 - (-8) = 12 unitsThe other side length is:
48/12 = 4 unitsPossible location of the other vertices (to the right from the given):
(5 + 4, -8) = (9, -8)and
(5 + 4, 4) = (9, 4)You have the following coins in your pocket: 5 quarters, 6 dimes, 2 nickels, and 12 pennies. What is the probability you will draw a dime and then a
penny?
5 quarters is 125 cents 6 dimes is 60 cents 2 Nickels are 10 cents and 12 pennies are 12 cents all that in total is 207
Probability is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
The probability of drawing a dime and then a penny is 9/50.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of coins = 6 dimes + 2 nickels + 12 pennies = 20
Number of dims = 6
Number of nickels = 2
Number of pennies = 12
The probability of drawing a dime.
= 6/20
= 3/10
The probability of drawing a penny.
= 12/20
= 6/10
= 3/5
Now,
The probability of drawing a dime and then a penny.
= 3/10 x 3/5
= 9/50
Thus,
The probability of drawing a dime and then a penny is 9/50.

A shirt cost $21 last month. This month the price decreased by 30%. What is the new price?
ASAP HELP
Answer:
Step-by-step explanation:
21x.30=6.3
21-6.3= 14.7
If shirt cost $21 last month and the price decreased by 30% then the new price is $14.7.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that a shirt cost is $21 last month.
The price decreased by 30% in this month.
We have to find the new price.
To find this we have to find 30 percentage of 21.
Convert 30 % to decimal value by dividing with 100 and then multiply the decimal value with $21.
30/100× 21
0.3×21
$6.3
So the amount decreased is $6.3
The new price we get by subtraction $6.3 from $21.
21-6.3
New price = $14.7
Hence, if shirt cost $21 last month and the price decreased by 30% then the new price is $14.7.

Answer:
BC ≈ 20.9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
BC² + AC² = AB²
BC² + 7² = 22²
BC² + 49 = 484 ( subtract 49 from both sides )
BC² = 435 ( take the square root of both sides )
BC = [tex]\sqrt{435}[/tex] ≈ 20.9 ( to the nearest tenth )

Use a graphing tool to solve the equation for x.
-4x - 1 = 5x + 4
A.
X-0.25
B.
X=-1.50
C.
X-1.25
D. X=-1
The equation -4x + 1 = 5x + 4 can be used to form a system of linear equations
The solution of x is x = -0.33
How to determine the solution?The equation is given as:
-4x + 1 = 5x + 4
Split the equation into a system of equations
y =-4x + 1
y = 5x + 4
Next, we plot the graph of both equations
From the graph (see attachment), we have the solution to be:
(x,y) = (-0.33, 2.33)
Remove the y value
x = -0.33
Hence, the solution of x is x = -0.33

Solve the following quadratic function
by utilizing the square root method.
Simplify your answer completely.
f(x) = 100 – 49x^2
Answer:
x = 10/7 or x = -10/7
Step-by-step explanation:
By using the completing the squares method, we have to divide the coefficient of the x term by 2, square it and add to both sides
From what we have here, the coefficient of the x term is 0
Thus, we have it that;
0 = 100 - 49x^2
We can proceed to use the difference of two squares here;
Whereby;
a^2 - b^2 = (a-b)(a + b)
0 = (10-7x)(10+7x)
10 - 7x = 0 or 10 + 7x = 0
7x = 10 or 7x = -10
x = 10/7 or x = -10/7

Indicate in standard form the equation of the line through the given points, writing the answer in the equation box
below.
PO.-4). Q15, 1)
Answer:
y = x-4
Step-by-step explanation:
The standard form is;
y = mx + b
where m is the slope and b is the y-intercept
we have the two points as (0,-4) and (5,1)
so we find the slope using the slope formula;
m = (y2-y1)/(x2-x1)
m = (1 + 4)/(5-0) = 5/5 = 1
The y-intercept value is the value of y when x = 0
We already have a point (0,-4) and the equation would be:
y = 1(x) + (-4)
y = x-4

Classify a triangle whose side lengths are 8, 16, and 18
A. Right Triangle
B. Acute Triangle
C. Obtuse Triangle
D. Isosceles Triangle
Answer:
Obtuse triangle
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.
In right angle triangle, one angle is 90°. The square of the longest side (hypotenuse) is equal to the sum of the square of the two sides.
An acute triangle is a triangle with acute angles (less than 90°). The square of the longest side is less than the sum of the square of the two sides.
An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles (less than 90°). The square of the longest side is larger than the sum of the square of the two sides.
An isosceles triangle is a triangle with two equal sides.
Given a triangle whose side lengths are 8, 16, and 18, the longest side is 18.
Since no two sides are the same hence it is not an isosceles triangle.
Also, 18² > 16² + 8²; therefore this is an obtuse triangle

According to the question,
circumference of a circle = perimeter of a square
2∏r = 4 × 22
