Hank is buying a shirt that originally cost $25.00. It was on sale two weeks ago for 10% off. Today, it is an additional 20% off the original price. How much is the shirt now?​

Answer:

7.5 pounds of muscles.

Step-by-step explanation:

Mr. Tan gained 5 pounds of solid fast twitching muscles during his last bulking phase lasting 24 days.

If this rate remains the same, then we can use the unitary method to calculate the amount of muscle he will gain in 36 days bulking phase.

Hence, within 24 days of the bulking phase, he gains 5 pounds of muscles.

So, within 36 days of the bulking phase, he will gain [tex]\frac{5}{24} \times 36 = 7.5[/tex] pounds of muscles. (Answer)

First, we calculated Mr. Tran's rate of muscle gain by dividing the total amount gained by the number of days. We then applied this rate to the asked time frame of 36 days. The result was approximately 7.48 lbs of muscle gain.

To solve this problem, we need to determine the rate of gain. Mr. Tran gained 5 lbs of solid fast twitching muscles in 24 days, so his rate of gain is 5 lbs / 24 days = 0.208 lbs/day. If Mr. Tran continues this rate for an extended period of 36 days, we can calculate the total gain by multiplying his daily rate by the number of days, i.e., 0.208 lbs/day * 36 days = 7.48 lbs. rounded to two decimal places.

So, if Mr. Tran’s bulking phase continues at the same rate for 36 days, he will gain approximately 7.48 lbs of muscle.

Answer:

9 tables

Step-by-step explanation:

Let x be the number of chairs sold and y be the number of tables sold.

Chairs are sold for $100 each, then x chairs cost $100x.

Tables are sold for $550 each, then y tables cost $550y.

Every day, the store can ship at most 21 pieces of furniture, then

[tex]x+y\le 21[/tex]

Store must sell no less than $5,700 worth of chairs and tables, then

[tex]100x+550y\ge 5,700[/tex]

If 10 chairs were sold, then [tex]x=10.[/tex] Substitute this value into both inequalities:

1. [tex]10+y\le 21\Rightarrow y\le 11[/tex]

2. [tex]100\cdot 10+550y\ge 5,700\Rightarrow 550y\ge 4,700\Rightarrow y\ge \dfrac{470}{55}=8\dfrac{6}{11}[/tex]

Hence, [tex]8\dfrac{6}{11}\le y\le 11[/tex]

The minimum number of tables that the the store must sell in order to meet the requirements is 9 tables

Answer:

Step-by-step explanation:

5/10 and 1/2 are both equivalent ratios resulting in half of themselves you can multiply these by any numbers but they will stay as half ratios such as 1:2 x 6 it would be 6:12 divide it by 6 and you have a half

Equivalent ratios have a multiplicative relationship, where multiplying both terms of a ratio by the same number results in another equivalent ratio. For example, multiplying the ratio 1:2 by 2 gives the equivalent ratio 2:4, showing that the ratios are proportional to each other.

Understanding Equivalent Ratios through Multiplication

We can explore the concept of equivalent ratios by looking at their multiplicative relationship. For instance, let's consider the ratios 1:2 and 2:4. These two ratios are equivalent because if we multiply both terms of the first ratio by 2, we get the second ratio. Mathematically, this can be expressed as 1x2/2x2 = 2/4, which is the same as the second ratio. Hence, the multiplication of both the numerator and the denominator of the first ratio by the same number (in this case, 2) maintains the ratio's equivalence to the second ratio.

This concept is crucial when dealing with proportions, unit rates, and unit scales. For example, if a map uses a unit scale of 1 inch = 100 feet, doubling the distance on the map to 2 inches would also double the actual distance to 200 feet, showing a direct multiplicative relationship between the two equivalent ratios.

Understanding how to use multiplication to find equivalent ratios is fundamental in solving problems that involve scaling, such as converting units or working with maps and models.

Step-by-step explanation:

Jenny drew a figure in art school and the figure is shown in the attached diagram.  

The diagram is a regular hexagon and it has rotational symmetry.  

Two of its sides is placed parallel to the x-axis.

Therefore, by rotating 60° the adjacent sides will become parallel to the x-axis and the figure remains the same and symmetric with respect to the coordinate axes. (Answer)

Answer:

Step-by-step explanation:

The fiven figure is a hexagon, which is a regular polygon with six equal sides.

Now, the symmetry of a hexagon is based on a 60° rotation, because each symmetrical portion of the figure enclosed a 60° angle.

Step-by-step explanation:

I assume you mean discriminant.

For a quadratic y = ax² + bx + c, the discriminant is b² − 4ac.

Here, a = -4, b = 2, and c = 1.  So the discriminant is:

(2)² − 4(-4)(1) = 20

Answer:

[tex]y = \frac{ - 4}{3} x + 3[/tex]

Step-by-step explanation:

[tex]using \: point \: slope \: form \\ y - y1 = m(x - x1) \\ y + 9= \frac{ - 4}{3} (x - 9) \\ y + 9= \frac{ - 4}{3}x + 12\\ y = \frac{ - 4}{3} x + 3[/tex]

The equation of the line in point-slope form passing through (9, -9) with a slope of -4/3 is y + 9 = -4/3 * (x - 9).

The point-slope form of a line's equation is expressed as y - y1 = m(x - x1). In this equation, 'm' represents the line's slope and (x1, y1) defines a particular point through which the line passes. In this scenario, the slope is given as '-4/3' and the point (9, -9). Consequently, by substituting these parameters into the point-slope form, we obtain the equation y - (-9) = (-4/3)(x - 9) or y + 9 = -4/3 * (x - 9).

Answer: B

Step-by-step explanation:

The common factor missing from both sets of parentheses in the polynomial 10x^3 + 35x^2 - 4x - 14 when factored by grouping is (2x + 7).

To factor the polynomial 10x3 + 35x2 - 4x - 14 by grouping, we must first split the polynomial into two pairs that have a common factor. We can pair the terms as follows: (10x3 + 35x2) and (-4x - 14).

Factoring out the greatest common factor from each pair, we get:

5x2(2x + 7)

-2(2x + 7)

Now, we can observe that both pairs contain the common factor (2x + 7). So, the polynomial can be re-written using this common factor:

5x2(2x + 7) - 2(2x + 7)

Drawn out completely, the factored form of the polynomial using the distributive property (also known as factoring by grouping) thus becomes:

(5x2 - 2)(2x + 7)

Answer:

If by bi-weekly you mean once every two weeks, then the friend who is payed bi-weekly has a higher annual salary. The same for if he is payed twice a week.

Step-by-step explanation:

1458 x 24 = 34992

1346 x 26 =34996

Let X = Individual ticket and y = couples tickets.

Set up two equations:

X + Y = 47 tickets sold

1X + 8y = $200

Rewrite the first equation as X = 47-y

Replace x in the second equation and solve:

1(47-y) = 8y = 200

Simplify:

47 - y + 8y = 200

Combine like terms:

47 +7y = 200

Subtract 47 from both sides:

7y = 153

Divide both sides by 7:

y = 153 / 7

y = 21.857

Because Y does not equal a whole number, the extra dollar does belong in the box.

Final answer:

Given the ticket prices and attendance, total sales amount to $71. The extra dollar found doesn't fit this, so it shouldn't be in the box.

Explanation:

To determine if the dollar Nola found belongs in the box, let's analyze the ticket sales. With individual tickets priced at $1 and couples tickets at $8 for two, we can calculate the total number of tickets sold. If there were 47 students in attendance, and assuming each couple bought the couples' ticket deal, the number of individual tickets sold would be (47 - number of couples) * 2 + number of couples.

Since each couple buys two tickets, the number of couples is 47 / 2 = 23.5, which means there were 23 couples and 1 individual. So, the total number of tickets sold is (47 - 23) * 2 + 23 = 71. Thus, the revenue from ticket sales should be $71.

If the cash box contains $200 and ticket sales total $71, then the extra dollar Nola found does not belong in the box. It's possible someone overpaid for a ticket or dropped a dollar accidentally, but it shouldn't be included in the revenue from ticket sales. Therefore, Nola should keep the dollar aside, perhaps to return it to its rightful owner.

A box of cereal states that there are 93 calories in a three fourths-cup serving. What is the unit rate for calories per cup?

126.7 ~= 127 calories

How many calories are there in 2 cups of the cereal?

127 *2 = 254 calories.

The unit rate for calories per​ cup is 124 calories and 2 cups of the​ cereal contain 248 calories.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given is a box of cereal which states that there are 93 calories in a

(3/4)th of a cup serving.

We can write -

3/4 cup serving contain → 93 calories

1 cup serving will contain → (93 x 4)/3 which is equivalent to 124 calories

Similarly, we can calculate for 2 cups of serving as -

1 cup → 124 calories

2 cups → (2 x 124) = 248 calories

Therefore, the unit rate for calories per​ cup is 124 calories and 2 cups of the​ cereal contain 248 calories.

Step-by-step explanation:

We can see here that the cost of the food bill and tip before sales tax was approximately $253.20.

To find the cost of the food bill and tip before sales tax, you first need to calculate the tip amount and then add it to the food bill.

Given:

Food bill = $214.58

Tip rate = 0.18 (18% expressed as a decimal)

First, calculate the tip amount:

Tip = Food bill × Tip rate

Tip = $214.58 × 0.18

Tip = $38.6244 (rounded to two decimal places)

Tip ≈ $38.62

Now, add the food bill and the tip to find the total cost before sales tax:

Total cost = Food bill + Tip

Total cost = $214.58 + $38.62

Total cost = $253.20

Therefore, the cost of the food bill and tip before sales tax was approximately $253.20.
