Answer: No

Step-by-step explanation:

to be proportional, both numbers have to increase by the same number

because if u multiply 6 by 2 you get 12, but when you multiply 10 by 2 you get 20, not 60 it would be proportional if you said 6 and 10 in to 12 and 20 in

Answer:

There were 130 hamburgers sold on Friday

Step-by-step explanation:

Assume that the number of hamburgers sold is x

∵ The number hamburgers sold = x

∵ The number of cheeseburgers sold was two times the number of

   hamburgers sold

∴ The number of cheeseburgers sold = 2x

∵ On Friday, the shop sold a combined total of 390 hamburgers and

    cheeseburgers

→ Add x and 2x, then equate the sum by 390

∴ x + 2x = 390

→ Add the like terms

∴ 3x = 390

→ Divide both sides by 3

∵ \(\frac{3x}{3}\) = \(\frac{390}{3}\)

∴ x = 130

∵ x represents the number of hamburgers

∴ There were 130 hamburgers sold on Friday

Multiply the diameter by pie which 3.14

Step-by-step explanation:

The angles COA and POC are 22.5 and 67.5 degrees respectively as POA is a right angled triangle.

POA is a right angle so it is 90 degrees.

POC +COA = 90  .....(1)

Also, POC is 3 times as large as COA.

Let's take COA, "x"

POC = 3x

Substituting the values in equation (1) as follows:

x + 3x = 90

4x = 90

x= 22.5

Therefore,

COA = 22.5°

POC = 22.5*3 = 67.5°

By using the midpoint rule, the value of n to approximate the integral is 9.24.

The integral of a function is a measure of the total area under the curve of the function over a given interval. The Midpoint Rule is a method used to approximate the value of an integral by dividing the interval into smaller subintervals, finding the midpoint of each subinterval, and using the height of the function at the midpoint to estimate the area of the subinterval.

In this specific problem, we are asked to approximate the integral of the function f(x) = sin root x from x = 0 to x = 48, using the Midpoint Rule with n = 4 subintervals. To do this, we divide the interval [0,48] into 4 equal subintervals of width

=> (48-0)/4 = 12.

The midpoint of each subinterval is calculated as follows:

1st subinterval: (0 + 12)/2 = 6

2nd subinterval: (12 + 24)/2 = 18

3rd subinterval: (24 + 36)/2 = 30

4th subinterval: (36 + 48)/2 = 42

Next, we find the height of the function f(x) = sin root x at each of these midpoints.

1st subinterval: sin root 6 = 0.77

2nd subinterval: sin root 18 = 0.97

3rd subinterval: sin root 30 = 0.87

4th subinterval: sin root 42 = 0.71

Finally, we multiply each height by the width of the subinterval to find the estimated area of each subinterval, and add up these areas to obtain the final estimate of the integral:

(0.77 * 12) + (0.97 * 12) + (0.87 * 12) + (0.71 * 12) = 9.24

So, our final estimate of the integral of f(x) = sin root x from x = 0 to x = 48 using the Midpoint Rule with n = 4 is 9.24. Rounding to 4 decimal places, our answer is 9.2400.

The Total mileage is "400" and the further solution can be defined as follows:

Let t become the time he spent commuting on the first day of his vacation.

It is then calculated as \(t + 2\).

\(\to 40\times(t+2) = 60(t) + 20 \\\\\to 40t+80 = 60t + 20 \\\\\to 80-20 = 60t + 40t \\\\\to 60 = 20t \\\\\to t=\frac{60}{20} \\\\\to t=\frac{6}{2} \\\\\to t= 3\\\\\)

It traveled \(40\times (3 + 2) + 20 = 40\times 5 + 20 = 200+20=220\) miles on its first day of operation.

The car traveled \(180\ miles\) on the second day, which was \(60 \ miles \times 3\).

Answer:

The answer is not complete. I will explain the concept of profit to you.

Step-by-step explanation:

We can determine profit deducting direct costs (cost price) of commodities from sales (selling prices) of the commodities.

Profit = Selling Price - Cost Price

Example:

A trader buys some dresses for #2,500 in May and agrees to pay for it in three months’ time. He sells off all the dresses in August for #4,500. The profit for the month is #2,000.

The formula for percentage profit is \(\frac{profit * 100}{cost price}\)

The formula for gross profit is Revenue – Cost of Sold Items

Profit Margin =  \(\frac{Total Income}{Net Sales}\) * 100

While Gross Profit Margin can be calculated as \(\frac{Gross Profit}{Net Sales}\) * 100

Any of these formulas can be used to calculate profit-related questions.

The requried measure of the ARC(WVY) is 250°. Option C is correct.

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,
We know that the tangent subtended to the circle from a common point then,
larger arc - smaller arc / 2 = angle between the tangent
10a - 4a -10 / 2 = 70
6a = 140 + 10
a = 150/6
a = 25

Now,

arc(WVY) = 10a = 10*25
                         = 250°

The correct option is B: The result of multiplying 7 3/8 by a number larger than 1 is less than 7 3/8.

Once kids have a firm grasp on right fractions, they are exposed to mixed numbers and improper fractions.

Divide the numerator and denominator to create a mixed fractions from an incorrect fraction. The solution to this problem is the whole number portion; the leftover portion is the numerator; its denominator stays the same.

We can convert the two fractions to decimal form in order to compare them.

7.375 is equivalent to 7 3/8, and

4/5 is equivalent to 0.8.

7.375 multiplied by 0.8 results in:

7.375 × 0.8 = 5.9

Since the result is 5.9, which is less than 7.375, it follows that 7 3/8 multiplied by 4/5 is less than 7 3/8.

Thus, the result of multiplying 7 3/8 by a number larger than 1 is less than 7 3/8.

Option (O log 7) refers to the base-10 logarithm of 7, represented as log10(7), which is not the same as ln (7). Optional (O log, 10) and (O log, e) mathematical expressions are not acceptable.

In mathematics, the logarithm is the reciprocal of a power. As a result, the exponent by which b must be raised to achieve a number x matches its logarithm in base b. For example, because 1000 = 103, the base-10 logarithm is 3, or log10 = 3. For example, the base 10 logarithm of 10 is 2, but the square of 10 is 100. Log 100 = 2. A logarithm (or log) is the mathematical word used to answer questions such as how many times a base of 10 must be multiplied by itself to get 1,000. The answer is 3 (1,000 = 10 10 10).

When you compute (In), you are calculating the natural logarithm of 7, which is indicated as ln(7) or loge (7).

As a result, the expression you'd be looking up the value of is: ln(7) or loge (7).

The sum of internal angles in a triangle is equal to 180

58 + 47 + x = 180

105 + x = 180 subtract 105 from both sides

x = 75

This is an acute triangle so each angle has to be less than 90 degrees in total we already have 105 and then lastly you can find out the last angle is kind of the same angle of angle 58 so its closer to 58 than 47 this is just a clue to the answer because I cant measure the angle from over the screen.

Answer:

Step-by-step explanation:

Given functions are,

f(x) = x + 6

g(x) = 2x + 6

(f - g)(x) = (x + 6) - (2x + 6)

                   = -x

(f . g)(x) = f(x) × g(x)

            = (x + 6)(2x + 6)

            = 2x² + 6x + 12x + 36

            = 2x² + 18x + 36

(f + g)(x) = (x + 6) + (2x + 6)

             = 3x + 12

(f + g)(1) = 3(1) + 12

Answer:

7 nickels and 14 dimes

Step-by-step explanation:

In tricky word problems like this you have to translate the word problem to algebraic equations

Let number of nickels = N
Let number of dimes = D

2 times as many nickels as dimes is saying that
the nmber of dimes = twice the number of nickels
and  translates to D = 2N  (1)

Value of D dimes = 10D cents since each dime is 10 cents
Value of N nickels = 5N cents since each nickel is 5 cents

$1.05 = 105 cents

So,

Value of dimes is $1.05 more than value of nickels translates to :

10D - 5N = 105  (2)

Since we have D = 2N we can use this relation to substitute for the value of D in terms of N
10D - 5N ==> 10(2N) - 5N = 20N - 5N = 15N

From (2) we get
15N = 105

N = 105/15 = 7
So there are 7 nickels

D = 2N = 2 x 7 = 14
So there are 14 dimes

Hence there are 7 nickels and  14 dimes

Let's check and see if our answer is right by plugging this value into the second equation

10D - 5N = 10 x 14 - 5 x 7 = 140 - 35 = 105 cents =$1.05
