If you estimate that a piece of wood measures 5.5cm if it actually measures 5.62cm what is the percent error of the estimate

The rate that best represents the relationship between the number of square feet and the number of gallons of paint is 156 square feet per gallon of paint.

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that a contractor has 18 gallons of paint that will cover 2,808 square feet. Therefore, the relationship between the number of square feet and the number of gallons of paint can be written as,

Number of square feet per gallon of paint

= Total area painted by 18 gallons / Total area of the paint

= 2,808 square feet / 18 gallons

= 156 square feet per gallon of paint

Hence, the correct option is C.

The slope is 0.003

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

the coordinates are (12000, 20) and (18000, 2)

so, slope= 18 / 6000

              = 0.003

The 3 in the thousandths place rounds down to 3, or stays the same, because the digit to the right in the ten thousandths place is 0.003.

Hence, the slope is 0.003.

The cost of one square inch of the cookie cake is $5.

What is area of circle?

The area encircled by a circle with radius r is known as πr^2 in geometry. Here, the Greek letter π stands for the constant proportion of a circle's circumference to its diameter, which is roughly equal to 3.14159.

Given:

A circular cookie cake costs $15.70.

The diameter of the cookie cake is 10 inches.

We have to find the cost of one square inch of the cookie cake.

Let the diameter is 10 inches.

So, the radius is 10/2 = 5 inches.

Area of circle = πr^2

                      = 3.14 x (5)^2

                       = 3.14 x 25

Area of circle  = 78.5 square inches.

So, the cost of one square inch cookie cake is,

78.5 / 15.70 = 5

Hence, the cost of one square inch of the cookie cake is $5.

78.9 kg.

To convert 78,900 grams to kilograms, we can divide the number of grams by 1,000. Since 1 kilogram is equal to 1,000 grams, dividing the number of grams by 1,000 will give us the equivalent number of kilograms.

Therefore, 78,900 grams is equivalent to 78,900 / 1,000 = 78.9 kilograms.

The similarity is that Sunni and Shia Muslims agree on the fundamental tenets of Islam, such as worshiping Allah as God, acknowledging Muhammad (Peace Be Upon Him) as the Prophet, and adhering to the Quran's teachings.

The difference is that Shia place a greater emphasis on Muhammad's family ancestry through a succession of Imams than Sunnis do on imitating the Prophet and his example.

All Shia and Sunni Muslims recognize the importance of the Quran; contrary to popular belief, Shi'a does not use a corrupted version of the Quran.

Shi'a and Sunni Muslims both use the Hadith, though they often prefer different collections of sayings.

They have different perspectives on imams. Imams are considered saints in Sunni Islam and must have a strong commitment to the Quran and Sunnah in order to be nominated. In Shia Islam, however, only God has the authority to name an imam. Only imams in Shia Islam have the authority to translate the Quran.

Answer: 48 3/4 miles/hour.

Step-by-step explanation: To find Daniel's speed in miles per hour, we need to first convert the time he rollerbladed to hours. We can do this by dividing the number of minutes he rollerbladed by 60 minutes per hour, as follows:

time in hours = 4 minutes / 60 minutes/hour = 1/15 hours

We can then use the formula for speed, which is distance divided by time, to find Daniel's speed in miles per hour as follows:

speed in miles per hour = distance in miles / time in hours

speed in miles per hour = 3 1/4 miles / 1/15 hours

speed in miles per hour = 3 1/4 miles * 15 hours/1

speed in miles per hour = 48 3/4 miles/hour

Therefore, Daniel's speed in miles per hour was 48 3/4 miles/hour.

Answer:

Check explanation!

Step-by-step explanation:

Daniel  rollerbladed at 15 mph, we know this because 60 divided by 4 = 15 (number of minutes in an hour divided by his time = answer)

The length of the hypotenuse side of the right triangle ΔXYZ, found using Pythagorean Theorem is b·√(10)

Pythagorean Theorem  indicates that the square of the length of the hypotenuse side of a right triangle is equivalent to the sum of the square of the legs of the right triangle.

The specified parameters of triangle are;

The hypotenuse of the triangle, ΔXYZ = [tex]\overline{YZ}[/tex]

The length of the legs of the right triangle are;

[tex]\overline{XY}[/tex] = b, and [tex]\overline{XZ}[/tex] = 3 × [tex]\overline{XY}[/tex]

Therefore;

[tex]\overline{XZ}[/tex] = 3 × b (substitution property of equality)

The length of the hypotenuse side can be calculated as follows;

Therefore;, according to Pythagorean theorem, we get;

[tex]\overline{YZ}[/tex]² = [tex]\overline{XY}[/tex]²  +  [tex]\overline{XY}[/tex]²

[tex]\overline{YZ}[/tex]² = b²  +  (3·b)² = b² + 9·b² = 10·b²

[tex]\overline{YZ}[/tex] = [tex]\sqrt{10\cdot b^2} = b \cdot \sqrt{10}[/tex]

Answer:

[tex]\textsf{a)} \quad y=1.8(3.2)^x[/tex]

[tex]\textsf{b)} \quad y=5(7)^x[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]

Given ordered pairs:

The y-intercept is the y-value when x = 0.

Therefore, as the y-intercept is 1.8, a = 1.8.

[tex]\implies y=1.8b^x[/tex]

Substitute point (1, 5.76) into the equation and solve for b:

[tex]\begin{aligned} y&=1.8b^x\\\implies 5.76&=1.8 \cdot b^1\\5.76&=1.8b\\b&=\dfrac{5.76}{1.8}\\b&=3.2\end{aligned}[/tex]

Therefore, the exponential equation is:

[tex]\boxed{y=1.8(3.2)^x}[/tex]

To complete the given table, simply substitute the values of x into the found equation:

Given ordered pairs:

The y-intercept is the y-value when x = 0.

Therefore, as the y-intercept is 5, a = 5.

[tex]\implies y=5b^x[/tex]

Substitute point (2, 245) into the equation and solve for b:

[tex]\begin{aligned} y&=5b^x\\\implies 245&=5 \cdot b^2\\49&=b^2\\b&=\sqrt{49}\\b&=7\end{aligned}[/tex]

My work:

Part A

---------     =    ---------

25.30             100

equals 2.02400

then round to get the tax amount which is $2.02

to find the bill cost we need to add the tax and the cost of the meal:

2.02 + 25.30 = 27.32

Part B

to find the tip we need to subtract the bill from the total lunch cost:

27.32 + t = 4.92                              (t = tip)

32.24 - 27.32 = 4.92

--------    =   --------

25.30         100
