From 18 wolves to 27 wolves, what was the increase? 27 - 18 is 9, so the increase was 9.
How much of 18 is 9? 9 / 18 is equal to 1 / 2, which is 0.5. To make 0.5 a percent we multiply by 100.
0.5 times 100 is 50%.

• I'm a 2-digit even number.
• The sum of my digits is 11.
• If you reverse my digits I
would be 27 less than I am.
Who am I?
Answer:
74
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
a = 7
a + b = 11 => 7 + b = 11 => b = 11 - 7 => b = 4
ab = 74

If we define left of the graph as "negative" and right of the graph "positive", we can see how most data points are shifted to the left.
∴ It would be negatively skewed.
It would not be 2. Symmetric because if we draw a line of symmetry, it is in fact unsymmetrical.
It would not be 3. Positively skewed because the data would be grouped towards the right.
It would not be 4. Exponentially skewed because the data is not strictly increasing bigger and bigger.

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

Write a cosine function that has a midline of 5, an amplitude of 3 and a frequency of 4/5
The cosine function with a midline of 5, an amplitude of 3 and a frequency of 4/5 is: f(x) = 3 * cos((8π/5) * x) + 5.
Given:
Amplitude (A) = 3
Frequency (f) = 4/5
Midline = 5
A cosine function with a midline of 5, an amplitude of 3, and a frequency of 4/5 can be expressed as:
f(x) = A cos(2π f x) + midline
Substituting these values into the equation, we get:
f(x) = 3 * cos(2π * (4/5) * x) + 5
Therefore, the cosine function is f(x) = 3 * cos((8π/5) * x) + 5.

To write a cosine function with a given midline, amplitude, and frequency.
y = 3 cos((4/5)x) + 5
Explanation:
In order to write a cosine function with a midline of 5, an amplitude of 3, and a frequency of 4/5, we can use the general form of the cosine function: y = A cos(Bx) + C. Here, A represents the amplitude, B represents the frequency, and C represents the midline.
Given that the midline is 5, the amplitude is 3, and the frequency is 4/5, we can substitute these values into the general form of the cosine function to get:
y = 3 cos((4/5)x) + 5

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.

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 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.

This so for number 5
Answer:
219.8
Step-by-step explanation:
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.

Solve: 2/v+1/5=3/w for w
Final answer:
To solve for w in the equation 2/v + 1/5 = 3/w, a series of algebraic steps including taking reciprocals and simplifying complex fractions leads to w = (15v)/(10 + 2v).
Explanation:
To solve the equation 2/v + 1/5 = 3/w for w, we must isolate w. This involves several algebraic steps. First, we can take the reciprocal of both sides of the equation in order to get w on one side:
∑1/(2/v + 1/5) = 1/(3/w)
Through the properties of reciprocals and complex fractions, the equation simplifies down to:
w = ∑3 × (v × 5)/(2×5 + v)
This can be further simplified by multiplying through by 3 and combining terms under a single denominator. After simplification, we obtain the relationship:
w = (15v)/(10 + 2v)

A. 44 - 4
O
2x - 15
O
o
O
c. 2x - 4
O
D. 4X – 15
Answer:
To find the width of the rectangle, we can use the formula for the area of a rectangle, which is the product of its length and width. In your question, you provided the area (A) as A = 8x^2 - 10x - 12, and the length is given as 4x + 3.
Let's denote the width as "w." So, we have:
Area (A) = Length (L) × Width (w)
A = (4x + 3)w
Now, we can solve for the width (w):
w = A / (4x + 3)
w = (8x^2 - 10x - 12) / (4x + 3)
Now, we need to simplify the expression for w. We can factor the numerator to see if there are any common factors:
w = [(2x - 4)(4x + 3)] / (4x + 3)
Now, we can cancel out the common factor of (4x + 3) in the numerator and denominator:
w = 2x - 4
So, the width of the rectangle is 2x - 4, which corresponds to option (C).
Step-by-step explanation:
The width of the rectangle is (8x^2 - 10x - 12) / (4x + 3)
Explanation:To find the width of the rectangle, we need to equate the expression for the area of the rectangle to a product of its length and width. In this case, we have the area A = 8x2 - 10x - 12 and the length is given by 4x + 3. So, we can set up the equation (4x + 3) * width = A. Let's solve for the width:
So, the width of the rectangle is given by the expression (8x2 - 10x - 12) / (4x + 3).
