Nikko needs to get his air-conditioner fixed. The repairman will charge Nikko a flat fee
of $50 plus an additional $20 for each hour he needs to work on it.
Write an equation to represent Nikko's total cost to repair his air-conditioner. Use t for total
cost and h for hours.

Answer:

$80.54

Step-by-step explanation:

The equation is A = P(1 + rt). You need to solve for A, the amount. P is the intial amount. r is the interest rate. t is the time in years. Convert 3 months into 3/12 years. Now plug in each of the numbers and solve.

Solution:

Given that,

Apply the distributive property to factor out the greatest common factor

35 + 50

By distributive property,

a(b + c) = ab + ac

First find the greatest common factor of 35 and 50

The factors of 35 are: 1, 5, 7, 35

The factors of 50 are: 1, 2, 5, 10, 25, 50

Then the greatest common factor is 5

Thus, factor out 5 from given expression,

35+50= 5(7+10)

5(7+10)= 5×7+5×10

5(7+10)= 35+50

5(7+10)= 85

Thus distributive property is applied

Answer:

(20 divided by 4) is the quotient

Step-by-step explanation:

In the expression the quotient part is 20÷4 and the quotient is 5.

The given expression is 5.3t - (20÷4) + 11.

In arithmetic, a quotient is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

In the given expression 5.3t - (20÷4) + 11,

20÷4=5

So, 5.3t - 5 + 11

5.3t + 6

Hence, in the expression the quotient part is 20÷4 and the quotient is 5.

Answer:

16 + sqrt(128)

Step-by-step explanation:

find the lengths of all 3 sides:

the side from (-9,8) to (-9,16) will be 16-8=8 (x stays constant)

The side from (-9,8) to (-17,8) is 8 (-9- (-17)=8)

The side from (-9,16) to (-17,8) will be found from the distance formula

d=sqrt((-17-9)^2 + (8-16)^2))

= sqrt(128)

So the perimeter will be these 3 numbers added together

P=sqrt(128) + 8 + 8

= 16 + sqrt(128)

which can simplify to:

= 16 + 4sqrt(8)

= 16 + 8sqrt(2) = 8+ sqrt(2)

Step-by-step explanation:

a) Our decoding strategy is to try to determine the mapping of code numbers to letters by looking at the range and/or frequency of the numbers. The minimum code value is 15, and the maximum is 41. We assume this means the value 15 corresponds to the letter A. Since the code is linear and the coefficient is 1, we assume this is a simple substitution code. We can find the letter number by subtracting 14 from the code number.

b) The decoding function will be ...

where alphabet[x] returns the x-th letter of the alphabet, and n is the code number. Subtracting 14 from the message numbers gives alphabet index number ...

Answer:

The perimeter would be 16

Step-by-step explanation:

you would do 5+5+3+3=16

Answer:

the answer is 16. trust me if you dont understand the explanation bc i am in 8th grade and have already done this.

plz mark brainliest.  

Step-by-step explanation:

the way you find perimeter is by adding up all the sides.

the top and bottom are the same number so all you need is one of them to know what the other one is. they give you the top number and it is 3 so that means that the bottom number is 3.

the left and right side are also the same number. they give you the left sides number and it is 5 so that means that the right sides number is 5.

if the top number was lets say 10 then that would mean the bottom number would be 10. and the same goes for the sides.

so now you know that the right side number is 5 and the bottom is 3.

now all you have to do is 5 + 5 ( because there are two 5's) and 3 + 3 (because there are two 3's) so 5 + 5 is 10 and 3 + 3 is 6 now you add 6 + 10 and you get 16.

Answer:

The formula for the average temperature in the ball is [tex]\bar T = \frac{2\cdot k\cdot R^{1/2}}{3}[/tex]. The limit of the average temperature for the ball does not exist.

Step-by-step explanation:

According to the statement, we have the following direct relationship:

[tex]T \propto \sqrt{r}[/tex]

[tex]T = k\cdot \sqrt{r}[/tex] (1)

Where:

[tex]T[/tex] - Temperature, measured in degrees Celsius.

[tex]r[/tex] - Distance from the center, measured in meters.

[tex]k[/tex] - Proportionality constant, measured in degrees Celsius per meter.

Under the assumption that ball is a continuous entity, we find that average temperature in the ball ([tex]\bar T[/tex]), measured in degrees Celsius, is represented by the following integral equation:

[tex]\bar T = \frac{1}{R}\cdot \int\limits^{R}_{0} {T(r)} \, dr[/tex] (2)

By applying (1) in (2), we find that:

[tex]\bar T = \frac{k}{R}\cdot \int\limits^{R}_{0} {\sqrt{r}} \, dr[/tex]

[tex]\bar T = \frac{2\cdot k}{3\cdot R}\cdot (R^{3/2})[/tex]

[tex]\bar T = \frac{2\cdot k\cdot R^{1/2}}{3}[/tex]

If the ball gets larger, then the limits associated to the average temperature diverges to the infinity as maximum exponent of the numerator of the rational function ([tex]n = \frac{1}{2}[/tex]) is greater than the maximum exponent of the denominator ([tex]n = 0[/tex]). Therefore, the limit of the average temperature for the ball does not exist.

Answer:It  equals -7/20 because Here's how to convert 0.35 to a fraction...There is not much that can be done to figure out how to write 0.35 as a fraction, except to literally use what the decimal portion of your number, the .35, means. Since there are 2 digits in 35, the very last digit is the "100th" decimal place. So we can just say that .35 is the same as -35/100. The fraction -35/100 is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 5. Why divide by 5? 5 is the Greatest Common Divisor (GCD) or Greatest Common Factor (GCF) of the numbers 35 and 100. So, this fraction reduced to lowest terms is -7/20. So your final answer is: 0.35 can be written as the fraction -7/20 Hope this helps... Plz mark me brainliest if the answer is correct... Stay safe and have a great weekend!!! :D

Step-by-step explanation:

The simplest fraction form id the number -35 is -7/100.

To write -0.35 as a fraction in simplest form, we need to convert the decimal number into a fraction.

Count the number of decimal places. In this case, we have two decimal places.

Write the decimal as a fraction with the denominator as a power of 10. Since we have two decimal places, the denominator will be 10^2, which is 100.

Place the decimal number over the denominator. In this case, -0.35/100.

Simplify the fraction by dividing both the numerator and denominator by their greatest common factor (GCF). In this case, the GCF of 35 and 100 is 5.

Dividing both the numerator and denominator by 5,

-0.35/100 = -35/500

Further simplify the fraction if possible. In this case, we can divide both the numerator and denominator by 5 again:

-35/500 = -7/100

So, -0.35 as a fraction in simplest form is -7/100.

The graph that shows the cost of the pants and shirts Johannes can buy, is a linear graph

The budget is given as

[tex]\mathbf{Budget = 300}[/tex]

If x represents the cost of each pair of pants.

Then the amount spent on 18 pairs of pants is:

[tex]\mathbf{Pants = 18x}[/tex]

If y represents the cost of each shirt.

Then the amount spent on 12 shirts is:

[tex]\mathbf{Shirt= 12y}[/tex]

So, the equation is:

[tex]\mathbf{Shirts + Pants =Budget}[/tex]

Substitute known values

[tex]\mathbf{18x + 12y =300}[/tex]

Divide through by 6

[tex]\mathbf{3x + 2y =50}[/tex]
