In a recent survey 5/8 of the Siamese cat said that they didn't mind having a lap up water from a bowl but another 3/16 admitted they would have preferred to use a straw instead of 39 of the Siamese cats gave one of these two answers how many were surveyed in total make sure your answer is fully reduced
Answer:
48 Siamese cats were surveyed
Step-by-step explanation:
Let x represent the total number of surveyed Siamese cats.
Since 5/8 of the Siamese cat said that they didn't mind having a lap up water from a bowl , hence:
Number of cats who lapped = (5/8)x
Also, 3/16 admitted they would have preferred to use a straw:
Number of cats who used straw = (3/16)x
Taking into consideration that 39 of the Siamese cats gave one of those two answers:
(5/8)x + (3/16)x = 39
(13 / 16)x = 39
x = 39 * 16 / 13
x = 48
48 Siamese cats were surveyed

The cost of 5 scarves is $31.25. What is the unit price?
Answer:
Step-by-step explanation:
Unit price = 31.25 ÷ 5 = 6.25
So each scarf costs 6.25
Answer:
$8.75 per scarf
Step-by-step explanation:
5 scarves costs $43.75 so to get the price of one scarf, we just need to divide by 5.
43.75 / 5 = 8.75
One scarf costs $8.75

A scale measures weight to the nearest 0.5 pound. Which measurement
shows an appropriate level of precision for the scale?
A. 140 pounds
B. 140.5 pounds
C. 140.75 pounds
O D. 141 pounds
Answer:
i think B... don't take my word though im not 100% cause it seems way too obvious on what the answer is lol
The measurement shows an appropriate level of precision for the scale is 140.5 pounds.
What is a place value?Place value, which is related to a digit's location in a number, is the amount that each digit is worth.
The scale measures weight to the nearest 0.5 pounds. This means that the scale can accurately measure weights that end in 0.5 or 0, and it rounds other weights to the nearest 0.5.
Among the given options, the weight that shows an appropriate level of precision for the scale is option B, 140.5 pounds.
This weight can be accurately measured by the scale and is reported to the nearest 0.5 pounds.
Option A, 140 pounds, may be rounded up or down depending on the actual weight and may not be an accurate measurement.
Option C, 140.75 pounds, is too precise for the scale to measure accurately to the nearest 0.5 pounds.
Option D, 141 pounds, is rounded up from 140.5 pounds and may not be an accurate measurement for the scale.
Therefore, 140.5 pounds.

Determine the equation of a circle with a center at (–4, 0) that passes through the point (–2, 1) by following the steps below. Use the distance formula to determine the radius: d = StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot Substitute the known values into the standard form: (x – h)² + (y – k)² = r². What is the equation of a circle with a center at (–4, 0) that passes through the point (–2, 1)? x2 + (y + 4)² = StartRoot 5 EndRoot (x – 1)² + (y + 2)² = 5 (x + 4)² + y² = 5 (x + 2)² + (y – 1)² = StartRoot 5 EndRoot
Answer:
Radius length: √5
Standard Form (Equation): (x + 4)^2 + y^2 = 5
Step-by-step explanation:
First we will determine the radius;
Center: (-4, 0)
Point on Circumference: (-2, 1)
d = √(-2 - (-4))^2 + (1 - 0)^2 = √(2)^2 + (1)^2
= √4 + 1 = √5
Therefore the radius is of length √5
Now the equation of a circle is in the form ((x - h)^2 + (y - k)^2) = r^2. The center is in the form (h,k) and r is the radius. Given this our equation would be (x - (-4))^2 + (y - 0)^2 = (√5)^2, or [simplified] (x + 4)^2 + y^2 = 5.

You work for 4 hours on Saturday and 8 hours on Sunday. You also receive a $50 bonus. You earn $164. How much did you earn per hour?
Answer:
Step-by-step explanation:
To find the hourly rate, we would first need to take the total earnings and subtract the bonus.
$164 - $50 = 114
This gives us the total money earned for hourly work.
Then we need to add the total hours worked: 4 + 8 = 12.
Lastly, we need to take the total money earned and divide it by the total hours worked: 114 / 12 = 9.50 or $9.50 per hour.
The equation could look like:
4h + 8h + $50 = $165

which table of values represent a linear relationship?
The equation of a line that represents the table is; y = 6x - 5.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b. Where slope = m and b = y-intercept.
Since we know that the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
To find the linear equation first we need slope;
(m) = (y₂ - y₁)/(x₂ - x₁)
= (1 + 11)/(1 + 1) = 12/2
m = 6.
Now, we have to take any one of these coordinate points and construct an equation in slope-intercept form;
- 11 = 6(-1) + b.
- 11 = - 6 + b.
b = - 5.
Therefore, y = 6x - 5 is our equation. the correct table represent a linear relationship is 2nd.

13) How do you know when to use the mean or median as the best measure of center?
Answer:
The mean is the most common measure of center. It is what most people think of when they hear the word "average". However, the mean is affected by extreme values so it may not be the best measure of center to use in a skewed distribution. The median is the value in the center of the data.
