Answer:
The answer is x = 13.
Step-by-step explanation:
first, move the constant to the right and change its sign, (+15)
3.75 x = 63.75 -15
next, subtract the numbers, (65.75 -15)
3.75x = 48.75
then, divide both sides of the equation by 3.75,
final answer, x = 13
Answer:
x = 13
Step-by-step explanation:
to solve this just simply collect the like terms and divide both sides by the coefficient of x
solution
3.75x +15 = 63.75
3.75x = 63.75 -15
3.75x = 48.75
divide both sides by the coefficient of x which is 3.75
3.75x/3.75 = 48.75/3.75
x = 13

Alan is printing photographs for an exhibition. He prints 11 photographs, and the total printing cost is $47.81. After 2 days, he gets 3 more photos printed. Alan estimates that the cost of the last 3 photos will be approximately $13.00. Is this a reasonable estimate?
Answer:
yes, this is a reasonable estimate
Step-by-step explanation:
47.81 x 3/11 = 13.04
The total cost for the first 11 photographs is $47.81.
To ascertain whether Alan's estimate for the cost of the last three photographs is reasonable, we will first compute the average cost of the first 11 photographs. Then, we will compare it to the estimated cost for the additional 3 photographs.
The total cost for the first 11 photographs is $47.81. To find the average cost per photograph, we divide this amount by the number of photographs:
$47.81 / 11 = $4.35 per photograph (rounded to the nearest cent).
Next, if Alan estimates the cost for 3 more photographs to be approximately $13.00, then the estimated cost per photograph for these would be:
$13.00 / 3 = $4.33 per photograph (rounded to the nearest cent).
Given that the average cost of the first 11 photographs is very close to the estimated cost of the additional 3 photographs, Alan's estimate is not only reasonable but also very precise.
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

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.

You are looking at two area rugs for your bedroom. One is a square with a side length of 6.3 feet. The other is a rectangle that is 4.8 feet by 8.2 feet. Which rug will cover the greater area? How much more area will it cover? Justify your response with mathematics.
Answer:
The square rug. The area of the rug is 39.69 ft² and is 0.33 ft² bigger than the rectangle rug.
Step-by-step explanation:
The find the area of a square, you multiply the length or the width (they all have the same length in a square) by the width (or the length), which would be the same exact number. So in that case—
The square has a side length of 6.3. To find the area of the square, we simply multiply 6.3 · 6.3 =39.69.
So, the area of the square is 30.69 ft²
————————————————————————————————————————
To find the area of a rectangle, you have to multiply the width by the length. (Or vise versa) This is showed by the following formula.
L·W=A
Where L=length, W=width, and A=area.
If the length is 8.2 and the width is 4.8, we can do the multiplicant equation that follows.
8.2·4.8= 39.36 ft².
Now that we have the area of both figures, we can compare them.
The square rug— 39.69
The rectangular rug— 39.36
Of we subtract the areas
39.69 and 39.36, we get the answer that the square rug is bigger by 0.33 ft².

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.

David swan, biked, and ran in the Camp Race. She biked twice as long as she ran, and swam 15 minutes more than she ran. Her total time for all parts of the race was 1 hour and 35 minutes. How many minutes did David spend on each part of the race?
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
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.

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.

What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
Given that, two numbers that are opposites and each more than 6 units away from 0.
Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it (8, -8).
Therefore, two numbers that are opposites and each more than 6 units away from 0 is (8, -8).
