Step-by-step explanation:
John drove from station A to station B a distance of 224 miles. On his way back, he increased his speed by 10 mph. If the journey back took him 24 minutes less, what was his original speed?
Answer: 70 mph
Step-by-step explanation:
224/x =224/x+10 +24/60
Solve equation
John's original speed was 70 mph.
Let's denote John's original speed as v (in mph).
The time taken for the first journey is 224 / v (hours).
His speed on the return trip is v + 10 mph.
The time taken for the return journey is 224 / (v + 10) (hours).
The time difference between the two journeys is 24 minutes, which is 24/60 = 0.4 hours.
Therefore, we set up the following equation:
224 / v - 224 / (v + 10) = 0.4
To solve this, we find a common denominator and solve for v:
224(v + 10) - 224v = 0.4v(v + 10)
2240 = 0.4[tex]v^2[/tex] + 4v
0.4[tex]v^2[/tex]+ 4v - 2240 = 0
Multiply by 10:
4[tex]v^2[/tex]+ 40v - 22400 = 0
Divide by 4:
[tex]v^2[/tex] + 10v - 5600 = 0
We solve this quadratic equation using the quadratic formula v = [-b ± √(b² - 4ac)] / 2a where a = 1, b = 10, and c = -5600:
v = [-10 ± √(10² - 4*1*(-5600))] / 2
v = [-10 ± √(100 + 22400)] / 2
v = [-10 ± √(22500)] / 2
v = [-10 ± 150] / 2
The possible solutions are:
v = (140 / 2) = 70 mph
v = (-160 / 2) = -80 mph (not feasible)
Thus, John's original speed was 70 mph.
5 Aaron wants to draw rectangles that each have an area of 36 square inches.

5 Aaron wants to draw rectangles that each have an area of 36 square inches.
The length and width of each rectangle are whole numbers of inches.
OK, we have Area=L×W where area is 36 and L and W are whole numbers, aka non-negative integers.
36=LW
a. A rectangle can have a width of 3 inches.
Sure, L=36/W = 36/3=12, a whole number. True
b. A rectangle can have a length of 8 inches.
W=36/L=36/8=9/2, not a whole number. False
C. A rectangle can have a length of 18 inches and a width of 2 inches.
Sure 18×2=36, our area. True
d. A rectangle can have a width of 6 inches and a perimeter
that is less than 36 inches.
L=36/6=6
It's a square, perimeter 6+6+6+6=24 which is of course less than 36
True
e. A rectangle can have a length of 9 inches, a width of 4 inches, and a perimeter equal to its area.
Perimeters can never really equal areas; they have different units. Let's just assume they mean they have the same number.
Area is 9×4=36, as desired. Perimeter is 9+4+9+4=26, not equal to its area.
False
This answer explains the possible dimensions for rectangles with an area of 36 square inches. The possible widths include 3 and 6 inches depending on the corresponding length. However, a length of 8 inches or 18 inches with a width of 2 inches, and a rectangle with a length of 9 inches and a width of 4 inches are false scenarios.
Explanation:The subject of these statements is about rectangles with an area of 36 square inches and their possible dimensions. For a rectangular area, you multiply the length by the width.
a. A rectangle can have a width of 3 inches: True. A rectangle with a width of 3 inches could have a length of 12 inches, giving an area of 36 square inches (3x12=36).b. A rectangle can have a length of 8 inches: False. There is no whole number that can be multiplied by 8 to give an area of 36.c. A rectangle can have a length of 18 inches and a width of 2 inches: False. Multiplying 18 by 2 gives an area of 36 square inches which is greater than the area allowable.d. A rectangle can have a width of 6 inches and a perimeter that is less than 36 inches: True. A rectangle with a width of 6 inches and a length of 6 inches has an area of 36 square inches and a perimeter of 24 inches, which is less than 36 inches.e. A rectangle can have a length of 9 inches, a width of 4 inches, and a perimeter equal to its area: False. A rectangle with a length of 9 inches and a width of 4 inches has an area of 36 square inches and a perimeter of 26 inches, and therefore the statement is false.Learn more about Rectangle Dimensions here:https://brainly.com/question/35474401

Here is the histogram of a data distribution. All class widths are 1.
1 2 3 4 5 6 7 8 9 10
What is the median of the distribution
The required median of the distribution is 7. Option B is correct.
What is the median?When a dataset is ordered, the median is the value that is exactly in the middle. It is a measure of central tendency that distinguishes between the lowest and top 50% of data.
Here,
To find the median of a distribution, we need to arrange the data in order from lowest to highest, and then identify the middle value. If there are an odd number of data points, the median is the middle value. If there are an even number of data points, the median is the average of the two middle values.
So, let's first list the values in ascending order:
1, 2, 3, 3, 4, 5, 5, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9, 9
The total number of data points is 20, which is even. Therefore, we need to find the average of the two middle values, which are the 10th and 11th values.
The 10th value is 7 and the 11th value is 7 as well, so the median is the average of these two values:
Median = (7+7)/2 = 7
Therefore, the median of the distribution is 7.

Answer:
The measure of angle Y is 76 degrees.
Step-by-step explanation:
A kite is a quadrilateral, so its angles must add up to 360 degrees. We can represent this with an equation:
W+X+Y+Z = 360
W+132+Y+76 = 360
We know that W=Y because side WX = side WY.
Y+ 208+Y = 360
2Y = 152
Y = 76 degrees
A square fits exactly inside a circle with all of its vertices being on the circumference of the circle.
The square has sides of lengths x cm
The area of the circle is 56cm^2
Give your answer to 3sf.
The side of the square is 5.9 cm
Step-by-step explanation:
Area of the circle = 56 square cm
Side of the square= x
Area = π(r x r)
56 = π (r x r)
√17.83 = r
r = 4.22 cm
Diameter = 8.44cm
The diameter is equal to the diagonal of the square.
8.44 = x√2
x = 8.44/√2
= 5.9 cm
The side of the square is 5.9 cm

A fashion store is having a sale advertising 'one
third' off all prices. If a pair of trousers costs £47.46
in the sale, what did it cost before?
To find the original price before the 'one third' discount, divide the sale price by 2 and then multiply by 3. The original price of the trousers would be £71.19.
Explanation:The fashion store sale offers a 'one-third' discount off regular prices. To find the original price of a pair of trousers that cost £47.46 after the discount, we should understand that this sale price represents two-thirds of the original price, as the discount removed one-third of the original price. Hence, to find the original price, we need to divide the sale price by 2 and then multiply the result by 3 (since the original price is equivalently 3 parts if two parts is the sale price). So, the original price is (£47.46 ÷ 2)*3 = £71.19.

d(1)=13 d(n)=d(n−1)+17 Find the 4 th term in the sequence.
Answer:
the 4th term is 64
Step-by-step explanation:
Given
d(1) = 13
d(n) = d( n -1) +17
First
d(2) = d(2-1) + 17
= d(1) + 17
= 13 + 17
= 30
d(3) = d(3-1) +17
= d(2) + 17
= 30 +17
= 47
d(4) = d(4-1) + 17
= d(3) + 17
= 47 +17
=64
To find the 4th term in the sequence defined by d(n)=d(n-1)+17, we can use the formula recursively to compute the subsequent terms. Starting with d(1)=13, we can find d(4) by adding 17 repeatedly.
Explanation:The sequence is defined by the formula d(n)=d(n-1)+17, with d(1)=13. To find the 4th term in the sequence, we can use the formula recursively. Starting with d(1)=13, we can find d(2) by adding 17 to d(1): d(2)= d(1) + 17 = 13 + 17 = 30. Continuing this pattern, we find d(3) = d(2) + 17 = 30 + 17 = 47. Finally, we find d(4) = d(3) + 17 = 47 + 17 = 64.

• If you reverse my digits I

Step-by-step explanation:
a + b = 11
ab - ba = 27
10a + b - 10b - a = 27
10a - a + b - 10b = 27
9a - 9b = 27
9(a - b) = 27
a - b = 27 : 9
a - b = 3
a + b = 11
a - b = 3
_______ +
a + b + a - b = 11 + 3
2a = 14

just multiply 157 times 1.4 and there you go!!
Since Sammy's stride is 1.4 meters, we simplify this to 1 meter for Estimation purposes. The field is 157 strides long, hence the estimated length of the field using compatible numbers is 157 meters.
To estimate the length of the field using compatible numbers, you first need to understand what each stride of Sammy's represents in standard units of length.
Sammy's stride is 1.4 meters.
We can simplify this to 1 meter for the sake of estimation.
Therefore, each stride Sammy takes is estimated to be roughly 1 meter.
Sammy finds that the field is 157 strides long.
To estimate the field's length in meters using compatible numbers, we simply take the number of strides Sammy counted (157) and replace his stride length with our simplified stride length (1 meter).
So, the estimated length of the field is 157 meters.
