2. Tom's brother saw an advertisement for a special at Muscle Fitness. Muscle Fitness is offering $20 off the one-time regular registration fee of $80. Membership is $15 per month with a mandatory additional $5 charge per month for equipment maintenance. Tom's brother tells Tom that he feels it is a better deal than Platinum Gym.
(a) Write an expression to represent the membership cost of Muscle Fitness for x months.
(b) Is Tom's brother right? Explain why or why not.

1) The equation for the change in temperature when x represents the number of degrees the temperature increased would be 68°F + x = 80°F.  2) Through the calculation, we find that the temperature in Buffalo, New York increased by 12°F from Saturday to the following Monday.

To answer the first part of the question, we need to write an equation showing the change in temperature from Saturday to Monday in Buffalo, New York. With x representing the number of degrees the temperature increased, we use the temperatures given: 68°F for Saturday and 80°F for the following Monday.

The equation representing this change would be: 68°F + x = 80°F.

To determine the value of x, which is the increase in temperature, we subtract the Saturday temperature from the Monday temperature:

80°F - 68°F = x
x = 12°F

Therefore, the temperature increased by 12 degrees Fahrenheit from Saturday to Monday.

Answer:

Rhea makes $3060 every month.

Step-by-step explanation:

In order to find this, we have to note that one-fourth of her salary is equal to $765. Give that fact, we know multiplying her rent total by 4 would give us the total salary.

$765 * 4 = $3060

Rhea's total earnings are calculated by multiplying her rent expenditure ($765) by 4, since the rent is one part of her four-part salary, resulting in total earnings of $3060.

If Rhea saved three parts of her salary and spent one part on rent, that means she spent a quarter (1/4) of her salary on rent. If $765 is the amount she spent on rent, we can calculate her total earnings by setting up a simple proportion, where the rent is 1 part, and the total salary is 4 parts (because 1 part spent + 3 parts saved = 4 parts total).

To find the earnings, we use the following equation:

1 part (rent) = $765

4 parts (total earnings) = X (the total salary we're trying to find)

Now we calculate X (total earnings) by multiplying the rent by 4:

X = $765 * 4 = $3060

This means that Rhea's total earnings are $3060.

It would take you 35 minutes.

Since it takes 10 minutes to peel 4 potatoes, you can assume it would take 30 minutes to peel 12 potatoes (mulitiplying both numbers by 3). Then you'd add 5, instead of 10 because you are peeling 2 more potatoes than 12, instead of peeling 4, you'd divide 10 by 2 to get half the time it would take to peel half as many potatoes. Finally, add 30 and 5 to get you final answer of 35.

I hope this helps!

It will take 35 minutes to peel 14 potatoes, as it takes 2.5 minutes to peel one potato.

Since you can peel 4 potatoes in 10 minutes, this means that you can peel one potato in 10/4 minutes, or 2.5 minutes per potato. To peel 14 potatoes, we would multiply the time it takes to peel one potato by the number of potatoes: 2.5 minutes * 14.

2.5 minutes * 14 potatoes = 35 minutes

So, it will take you 35 minutes to peel 14 potatoes.

Content of DEET in 1 ml of insect repellent = 0.9811 ml

To find the DEET content in 20 ml of insect repellent, we have to multiply.

So, content of DEET in 20 ml of insect repellent = 20 × 0.9811 = 19.622 ml.

Hence, the correct answer is (A).

Answer:

Answer: A. 19.622

Step-by-step explanation:

20x0.9811=19.622

Answer:

2 7/10 simplified 2 1/10

Solution

Part A

The general form of the n-th term = a + (n-1)d

Here we are given the 8th term A8 = 28 , common difference (d) = 6

A8 = a + (n - 1) 6

28 = a + (8- 1)6

28 = a + 7*6

28 = a + 42

a = 28 - 42

a = -14

Part B

n-th term  is 760. a = -14 and d = 6.

Plugging in the values in the general form, we get

760 = -14 + (n -1)6

760 = -14 + 6n - 6

760 = -20 + 6n

6n = 760 + 20

6n = 780

Dividing both sides by 6, we get

n = 780/6 = 130

The value of n is 130

Answer:

6  brochures

Step-by-step explanation:

Each brochures is 23 centimeters wide.

The table is 1.5 meters wide.

To know how many brochures can be placed side by side on the table first you have to calculate how many centimeters there are in 1.5 meters wide.

One meter equals 100 centimeters.

Therefore in 1.5 meters there are:

[tex]1.5*100 = 150[/tex] centimeters.

Now we must calculate in how many parts of 23 cm can be divided 150 cm.

To do this we made the division of 150 between 23

[tex]\frac{150}{23}= 6.522[/tex]

This means that up to 6 brochures of 23 cm can be placed side by side on the table

Step-by-step explanation:

because 5.78 can be written as a fraction:-   5 78/100 or 5 39/50

C and D do not equate to 5.78

Answer:

A. [tex]5.78=5.787878[/tex]

Step-by-step explanation:

We have been given a number 5.78. We are asked to choose the correct statement which shows that 5.78 is a rational number.

Upon looking at our given choices, we can see that only option A is the correct choice as it has repeating digits (78) after decimal.

We know that a number with repeating decimals can be written as a fraction, therefore, option A is the correct choice.

Yes, they are both functions.

they are both functions.. when i was taking algebra my teacher taught me the straight edge trick.. you take a ruler and run it across the graph, if the ruler touches more than one point on the graph at one time, it is not a function.. but since the ruler did not touch more than one point at one time on both of these, they are both functions.

The first one the p=30 ft  and a=15 ft and the second one is p=26 km and a= 36 km

A circle whose center is located at point (a, b) having a radius of length r has the equation:

(x -a)² + (y -b)² = r²

Therefore, radius = 21

A circle whose center is located at point (-5, -7) having a radius of length r has the equation. Therefore, radius will be 21.

If a circle O has a radius of r units length and it has got its center positioned at (h, k) point of the coordinate plane,

then, its equation is given as:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

We have been given the equation of the circle as

[tex](x+5)^2+(y+7)^2=21^2[/tex]

From comparing the general equation

Here, (h, k) = (-5, -7)

and the radius r = 21.

Answer:

[tex]0.777=0.\overline{7}[/tex]

Step-by-step explanation:

We are asked to write 77.7% as a decimal.

We know that percent means per hundred.

To write 77.7% as decimal, we will divide 77.7 by 100 as:

[tex]77.7\%=\frac{77.7}{100}[/tex]

Move decimal to left by two digits.

[tex]77.7\%=\frac{77.7}{100}=0.777[/tex]

Let us set 0.777 equal to x as:

[tex]x=0.777[/tex]

We can see that our decimal has three 7 digits after decimal, therefore, 1 digit is repeating after decimal.

First, find the vertices of the shaded region. You can do this my graphing or by solving a system of equations for each pair of functions. I am going to find them by graphing.

x ≥ 0 and y ≥ 0 place the shaded region in the first quadrant with a vertex at (0, 0)

now graph y ≤ 3.  a vertex is at (0, 3)

now graph y < -2x + 5. a vertex is at (1, 3). the other vertex is the x-intercept (when y = 0).

                  0 = -2x + 5

                  -5 = -2x

                   [tex]\frac{5}{2} = x[/tex]     So, the vertex is  [tex](\frac{5}{2} , 0)[/tex]

Next, input the coordinates of the vertices into the objective function.

C = -6x + 5y

(0, 0): C = -6(0) + 5(0)

             =    0    +   0

             =          0

(0, 3): C = -6(0) + 5(3)

             =    0    +   15

             =          15

(1, 3): C = -6(1) + 5(3)

             =  -6  +  15

             =       9

[tex](\frac{5}{2} , 0)[/tex]: C = -6(\frac{5}{2}[/tex]) + 5(2)

             =  -15  +  10

             =       -5

The maximum is C = 15 which occurs at vertex (0, 3)

I'm thinking Jim ran faster. Sorry if I'm wrong

Hello, I'm Jenny and I'm happy to help you! :)

Lets set up an equation for this problem.

Jim: 200 meters | 30.4 seconds

Mac: 100 meters | 30.4 seconds

We both know that they ran different amount of meters in the same amount of seconds so whoever completed the furthest amount of meters ran the fastest.

Jim: 200, Mac: 100.

Since 200 is higher than 100, Jim ran the furthest amount of meters therefore,

Jim ran the fastest.

The answer to #1 is the first/tallest blue bar. The way that it compares to a bacteria cell is that they both have the same water percentage.

Proteins make up a larger amount of an animal cell. I know this because the blue bar (representing the animal cell) is taller under the section of proteins than it is under nucleic acids.

I can tell that the chemical composition of bacterial and animal cells have a lot in common. All of the purple and blue bars match up almost perfectly, meaning that their compositions are almost the same.

Parentheses> Exponents >Multiplication> Division> Addition> Subtraction

Answer:  Jose spent a total of $44.52.

Step-by-step explanation:  Given that Jose buys 4 pounds of sausage that cost $8.79 per pound, a bottle of mustard that costs $1.38, and two loaves of Cuban bread that cost $3.99 each.

We are to find the total amount of money that Jose spent.

The amount of money spent on sausage is given by

[tex]A_s=4\times8.79=\$35.16,[/tex]

the amount of money spent on the bottle of mustard is

[tex]A_m=1\times1.38=\$1.38[/tex]

and the amount of money that spent on the  loaves of Cuban bread is

[tex]A_c=2\times3.99=\$7.98.[/tex]

Therefore, the total amount of money spent by Jose is given by

[tex]A=A_s+A_m+A_c=35.16+1.38+7.98=\$44.52.[/tex]

Thus, Jose spent a total of $44.52.
