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:

$7.65

Step-by-step explanation:

Given that:

Money used for buying the four salmon steaks = $22.95

Weights of steaks in pounds = 0.68, 0.74, 0.77, and 0.81

To find:

Price of salmon steak per pound, to the nearest cent = ?

Solution:

Total weight of all 4 steaks = 0.68 + 0.74 + 0.77 + 0.81 = 3

Here, to find the price of salmon steak per pound we need to divide the total money used to buy salmon steaks with the total weight of salmon steaks in pounds.

Price of salmon steak per pound = [tex]\frac{22.95}{3} = \$7.65[/tex]

Final Answer: [tex]b = -1[/tex]

Steps/Reasons/Explanation:

Question: [tex]7b - 2/5 = 6b - 7/5[/tex] equations with variables on both sides: decimals & fractions.

Step 1: Subtract [tex]6b[/tex] from both sides.

[tex]7b - \frac{2}{5} - 6b = -\frac{7}{5}[/tex]

Step 2: Simplify [tex]7b - \frac{2}{5} - 6b[/tex] to [tex]b - \frac{2}{5}[/tex].

[tex]b - \frac{2}{5} = -\frac{7}{5}[/tex]

Step 3: Add [tex]\frac{2}{5}[/tex] to both sides.

[tex]b = -\frac{7}{5} + \frac{2}{5}[/tex]

Step 4: Simplify [tex]-\frac{7}{5} + \frac{2}{5}[/tex] to [tex]-1[/tex].

[tex]b = -1[/tex]

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.

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

Step-by-step explanation:

$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

Answer:

x = -4  y = -2(-4) - 4 = -12

x = -2  y = -2(-2) - 4 = 0

x = 0  y = -2(0) - 4 = -4

x = 2  y = -2(2) - 4 = -8

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

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

Answer: (1, -2) (4, -8) (-5, 10) ( 3, -6)

Step-by-step explanation:

You solve all of them by inputting the x value's into the x in the equation

Here:

y= -2(1)   x=1 y= -2

y= -2(4)   x=4 y= -8

y= -2( -5)  x= -5 y= 10

y= -2(3)   x= 3    y= -6

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.

Answer:

e value = 6

i value = 1

Step-by-step explanation:

The system of equation are;

e - i = 5...(1)

e + 3·i = 9...(2)

Making e the subject of equations (1) and substituting the value of e equation (2) gives;

From equation (1), e - i = 5, we have, e = 5 + i

Substituting the value of e in equation (2), e + 3·i = 9 gives;

e + 3·i = (5 + i) + 3·i = 5 + 4·i = 9

4·i = 9 - 5 = 4

i = 4/4 = 1

i = 1

From e = 5 + i, we have;

e = 5 + i = 5 + 1 = 6

e = 6

Therefore;

e value = 6

i value = 1
