The equation would be [tex]6c + 10f[/tex].

The expression which represents the total cost of all of the pizzas they order is 6c + 10f.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Cost of cheese pizza = $6

Cost of four-topping pizzas = $10

Number of cheese pizza order = c

Number of four-topping pizzas order = f

Hence,

Total cost cheese pizza = Cost of cheese pizza*Number of cheese pizza order

⇒Total cost cheese pizza = 6*c = 6c

Similarly,

Total cost of four-topping pizzas = Cost of four-topping pizzas*Number of four-topping pizzas order

⇒Total cost of four-topping pizzas = 10*f = 10f

Hence, total cost of all of the pizzas they order

                    = Total cost cheese pizza + Total cost of four-topping pizzas

⇒ total cost of all of the pizzas they order = 6c + 10f    

Hence,The expression which represents the total cost of all of the pizzas they order is 6c + 10f.

Multiply by 1000 and divide by 3600

Step-by-step explanation:

We know that in 1 km we have 1000 m and in 1 h we have 60 minutes and each minute have 60 seconds, then we multiply 60*60 to know how many seconds are in an hour and we have that 1 h have 3600 s. Using a conversion factor we have:

[tex]\frac{km}{h}(\frac{1000 m}{1km})(\frac{1h}{3600s})[/tex]

With this we can see that to convert a quantity from kn/h to m/s we must multiply by 1000 and divide by 36000

To convert from kilometers per hour to meters per second, you should multiply by 1000 (to convert kilometers to meters) and then divide by 3600 (to convert hours to seconds). An example with a speed of 50 km/h would result in approximately 13.9 m/s after conversion.

To convert a quantity from kilometers per hour (km/h) to meters per second (m/s), the correct approach is (a) multiply by 1000 and then divide by 3600. This is because 1 km is equal to 1000 meters, and 1 hour is equal to 3600 seconds. Therefore, to change the unit from km/h to m/s, you need to perform these conversion operations.

Let's consider an example. If you have a speed of 50 km/h and want to convert it into m/s, here's the step-by-step process:

Answer:

total management fee is $16200

Step-by-step explanation:

given data

leases = $60000 per year

time = 7 year

fees 1st year = 7%

fees 2nd and 3rd year = 5%

fees remaining year = 3%

to find out

total management fee

solution

we find here commission for each here

for 1st year = 7% of $60000 = $4200   ............1

for 2nd and 3rd  year = 5% of $60000 = $3000   ............2

for remaining year = 3% of $60000 = $1800   ................3

and that is 4 year so fees = 1800 × 4 = $7200   ................4

now add all these to get total

total fees = 4200 + 3000 + 1800 + 7200

total fees = 16200

so total management fee is $16200

Sydney Blackwell's total management fee for a 7-year period, with varying annual rates applied to a $60,000 lease, amounts to $17,400.

Calculating Sydney's Total Management Fee

To calculate Sydney Blackwell's total management fee for managing an office building, we need to apply the corresponding percentage rates to the annual lease amount over the span of the management agreement. The lease amount is $60,000 per year, and the management agreement spans 7 years with varying fees each year.

Here's the breakdown of fees per year and total fee calculation:

Adding up the fees from all years:

$4,200 + $6,000 + $7,200 = $17,400

Therefore, the total management fee Sydney will receive over the 7-year period is $17,400.

Step-by-step explanation:

Think first in a simpler case. In a 2x2 matrix the determinant is zero if two columns or rows are proportional. So Alice writes the first number, then Bob write the same number in the same column but in the other row. Bob repeat the procedure after Alice's second number, and win.

If the matrix is nxn where n is even (like 2008) Bob will win following the previous procedure. Alice writes a number anywhere, Bob writes the same number in the same column in the above (or below) row.  Every time Alice write a number in the same row as her first one, Bob copy that number in the above (or below) row. Any other rows are not important, i.e, the determinant will be zero with any values in them.

b. The radius of the first ferris wheel was 179% of the radius of the navy pier ferris wheel

c. The wheel was moving at 0.70 [tex]\frac{rad}{min}[/tex]

Step-by-step explanation:

Navy pier wheel circumference = Cn

First ferris wheel circumference = Cf

Cn = 0.56*Cf

a.

Circumference Perimeter = 2*π*Radius

Navy pier wheel radius = Rn

First ferris wheel radius = Rf

Cn = 0.56*Cf

2*π*Rn = 0,56*2*π*Rf        (equation 1)

dividing both sides by 2π

Rn = 0,56*Rf

b.

From equation 1

2*π*Rn = 0,56*2*π*Rf

dividing both sides by 2π

Rn = 0.56*Rf

United states population = 319 million

a)

        823 000 = 8.23 x 10 ⁵         move the decimal point 5 places to the left

 319 000 000  = 3.19 x 10⁸         move the decimal point 8 places to the left

b)

To find the answer, just divide the USA population by the Columbus, Ohio population

       3.19 x 10⁸ / 8.23 x 10 ⁵ = 387.6 ≈ 388 times

Final answer:

a) The population of Columbus, Ohio in scientific notation is 8.23 × 10⁵ and that of the United States is 3.19 × 10⁸.  and b) the US population is 388 times larger as compared to Columbus.

Explanation:

(5)(-2b)= -10b

9a-9b+10a-10b

9a+10a-9b-10b ( combine like terms)

Answer : C. 19a - 19b

To simplify the expression 9(a - b) + 5(2a - 2b), we first distribute each term in the parentheses by the factor outside the parentheses and then gather like terms, getting 19a - 19b.

To solve this problem, we need to distribute each term in the parentheses by their respective factor outside the parentheses and then collect like terms.

Step 1: Distribute the terms

9(a - b) becomes 9a - 9b

5(2a - 2b) becomes 10a - 10b

Step 2: Collect like terms

9a + 10a = 19a

-9b - 10b = -19b

So, the expression 9(a - b) + 5(2a - 2b) simplifies to 19a - 19b, which is answer choice C.

Answer:

  1196 mi

Step-by-step explanation:

The latitude difference is 17°18', so is about 0.301942 radians. Then the arc length is ...

  s = r·θ = (3960 mi)(0.301942) ≈ 1196 mi

The distance between City A and City B, given their latitudes and the radius of the Earth, is found using the arc length formula (length = radius x angle in radians) to be approximately 2011 miles.

The subject of this question is Geography and it entails finding the distance between two cities located at different latitudes on Earth. The difference between the two latitudes is used to find the distance. Since the Earth is a sphere, we can use the formula for the length of an arc to find the distance between these two cities. To do so, subtract the latitude of City B (19 degrees 44 prime) from the latitude of City A (37 degrees 2 prime) to get the difference in degrees which is equal to 17 degrees 18 prime. Convert this to decimal form by dividing the prime by 60 (17 + 18/60 = approx. 17.3 degrees).

Then use the formula for the length of an arc: length = radius x angle (in radians). The radius of the Earth is given as 3960 miles and the angle in radians is obtained by multiplying the angle in degrees by π/180. Therefore, the distance is 3960 miles x 17.3 x π/180 = approximately 2011 miles. As such, City A and City B are estimated to be about 2011 miles apart.

Answer:

Security B is riskier than Security A.

Step-by-step explanation:

Security A and B have the same historical average annual return which is 7%, meaning that both of them have had the same results over the years.

However, the standard deviation of A is 3% and the standard deviation of B is 9%, therefore we can conclude that Security A is safer than Security B because a low standard deviation indicates that the annual returns tend to be close to the average (mean), while a high standard deviation indicates that the annual returns are spread out over a wider range of values.

For example:

Security A has this values over the years:

6, 7, 8, 7 where mean is 7.

Security B has this values over the years:

1, 13, 4, 12 where the mean is also 7.

But, A has a lower standard deviation and B a higher one, therefore, Security B is riskier.

Explanation with the help of discrete variables and continuous variables.

Step-by-step explanation:

We have to tell that which of the following can be an exact number.

This can be done with the approach of discrete and continuous variables.

Discrete variables are the variables that are countable and cannot be expressed in decimal form. They are point estimated.

Continuous variable are the variable that are estimated with the help of an interval. Their values can be expressed with the help of a decimal expansion. They are not countable.

a) Mass of a paper clip, Surface are of dime, Inches in a mile, Ounces in pound, microseconds in a week

Since all mass, area, weight(ounces), time, length(inches) are continuous variable, they can be estimated with the help of an interval. Thus, they can have exact number but not always.

b) Number of pages in a worksheet

Since this is a discrete quantity and it is countable. Thus, it will always have a point estimation and are exact numbers always.
