To find the perimeter of a quadrilateral use the distance formula to find the length of each side, and then add the lengths so option (A) will be correct.
What is a perimeter?Perimeter is the addition of an external measure of sides it will always positive.
A perimeter is a length and has a degree of the unit as one.
For example
Perimeter of square = side + side + side + side
Perimeter of circle = πd where d is dia of the circle.
To find the perimeter of the quadrilateral we need to find all four side and add them because the perimeter is nothing but the sum of external sides.
So,
By using the distance formula we can find the distance between two points or the distance of a side of a quadrilateral because coordinates are given.
Hence "Use the distance formula to find the length of each side, and then add the lengths"

Step-by-step explanation:
To find the range, take your largest number and subtract it to
your smallest number. 15-7 is 8. Therefore, your range is 8.
Answer:
8 is the range
Step-by-step explanation:
Step 1: Find the range
To find the range, subtract the lowest number from the highest number.
Example: 5, 9, 15
What is the highest number → 15
What is the lowest number → 5
What is the range 15 - 5 = 10 is the range
Problem: 7, 15, 12

To find the number of whole numbers between 100 and 999 with a sum of 9 as their digits, we can use combinations. By selecting the digits using the given steps, we find that there are 50 such numbers.
Explanation:To find how many whole numbers between 100 and 999 have 9 as the sum of their digits, we can use the concept of combinations. We can select 3 digits (from 0 to 9) to form a number, and there are 10 choices for each digit. However, we need to consider the constraint that the sum of the digits should be 9. So, we can select the digits such that the first digit and second digit will have a sum of 9, and the third digit will also be 9. This can be done in the following steps:
Select a number from 0 to 9 for the first digit.Select a number from 0 to the remaining digits to get a sum of 9 (e.g., if the first digit is 5, then we can choose the second digit from 0 to 4).The third digit should always be 9 to satisfy the condition.Applying these steps, we have 10 choices for the first digit, 5 choices for the second digit (since the second digit cannot be greater than the first digit to achieve a sum of 9), and only 1 choice for the third digit. Therefore, the total number of whole numbers between 100 and 999 with a sum of 9 as their digits is 10 * 5 * 1 = 50.

Which shows the image of quadrilateral ABCD after the transformation R0 90?
Answer:
second picture
Step-by-step explanation:
The rule to rotate a point counterclockwise about the origin is:
Or in words, we switch the coordinates of the point and change the sign of the y-coordinate.
We know from the first picture that the coordinates of our quadrilateral ABCD are A = (-1, 0), B = (0, -1), C = (-2, -3), and D = (-3 , -2), so let's apply the rotation rule to each one of those points:
Now we know that the coordinates of the quadrilateral after a rotation of 90° are A' = (0, 1), B' = (1, 0), C' = (3, -2), and D' = (2, -3), which corresponds to the second picture

In ΔQRS, the measure of ∠S=90°, the measure of ∠Q=54°, and RS = 26 feet. Find the length of QR to the nearest tenth of a foot.
You may use the law of sines, that states that in every triangle the ratio between a side and the sine of the opposite angle is constant.
So, in your case, we have
[tex]\dfrac{QR}{\sin(\hat{S})}=\dfrac{RS}{\sin(\hat{Q})}[/tex]
We know that [tex]\hat{S}[/tex] is 90 degrees, so its sine is 1. Also, we know that RS=26. So, the equation becomes

Step-by-step explanation:
First, you have to make these into 2 different shapes. Two different prisms. You can see all the dimensions on the right shape, but not the left. How do you know the width? Well, since the width is the same for the WHOLE figure, the width for both shapes is the same. To find the volume of a rectangular prism, you need to multiply the length, width, and height.
Length * height * width
Shape 1: [tex]8 * 3 * 5 = 120[/tex] cm
Shape 2: [tex]2*6*5=60[/tex] cm
Then, you add the volumes of the 2 shapes to get the final volume.

A 270-mile highway has a toll booth at the beginning, a toll booth every 45 miles, and then a final toll booth at the end. A
passenger vehicle must pay a $2.75 toll each time that it passes by a toll booth. There are no additional tolls when exiting
the highway.
Josh entered the turnpike at its beginning and exited after driving 120 miles. How much in toll fees did Josh have to pay?
Answer:
$8.25
Step-by-step explanation:
270 sectioned out by 45s is 7 toll booths on the highway. That means theres a toll booth at 0 mi, 45, 90, 135, 180, 225 and 270 mi. If Josh exits after 120 mi, he only hits the booth at the beginning and then the last one at 90 mi because he doesn't reach the next one at 135 mi. $2.75 per toll booth and if he passed 3, then 2.75 x 3 = $8.25.

Answer:
She biked 40 minutes.She ran 20 minutes.She swam 35 min.
Step-by-step explanation:
since you have 95 minutes for all parts first subtracted 15 from what she swam the you have four equal parts left the time she ram then twice she ran she biked and then the she swam 15 minutes More that she ran so you dived 95-15 which is 80 80/4 is 20 so she ran 20 min so 20 x 2 is 40 for she bike 40 then 20+15 is 35 so 40+20+35=95 an hour an 35 minutes

A square rug has an inner square in the center. The side length of the inner square is x inches and the width of the outer region is 4 in. What is the area of the outer part of the rug?
To find the area of the outer part of the square rug, calculate the total area using the length of the entire square (x + 8)² and subtract the area of the inner square (x²), yielding (x + 8)² - x² square inches.
Explanation:The subject of this question is geometry - specifically area calculations in mathematics. The student is asking for the area of an outer part of a square rug. The main rug is comprised of a square within another square, with the side length of the smaller square being x inches and the distance in between the small and large square (representing the outer region) being 4 inches.
To calculate the area of the outer region, first, we need to calculate the side length of the outer (entire) square. This would be x + 2*4 = x + 8 inches (4 inches from each side). The total area of the rug would be squared side length of the outer square, which is (x + 8)² square inches.
Subsequently, the area of the inner part of the rug can be calculated as x² square inches (since it's a square). Therefore, the area of the outer part of the rug would be obtained by subtracting the area of the inner square from the total area of the rug, yielding: (x + 8)² - x² square inches.

To find the area of the outer part of the rug, we first need to find the area of the entire rug and then subtract the area of the inner square.
Let s be the side length of the outer square.
The area of the entire rug is the area of the outer square:
Area of outer square = [tex]s^2[/tex]
Since the width of the outer region is 4 inches, we know that the side length of the outer square is [tex]\( s = x + (2 \times 4) = x + 8 \).[/tex]
So, the area of the outer square is:
Area of outer square = [tex](x + 8)^2[/tex]
Now, let's find the area of the inner square:
Area of inner square = [tex]x^2[/tex]
The area of the outer part of the rug is the difference between the area of the outer square and the area of the inner square:
Area of outer part = Area of outer square - Area of inner square
[tex]\[ = (x + 8)^2 - x^2 \][/tex]
Now, let's expand and simplify:
[tex]\[ = x^2 + 16x + 64 - x^2 \][/tex]
= 16x + 64
So, the area of the outer part of the rug is 16x + 64 square inches.
