at the tasty bakery cupcakes cost fifty cents each. bagels cost a dollar twenty five. how much more do two Bagels cost than two cupcakes?

The mathematical expression for the sum of b and 5 times 2 is b + (5 × 2).

The expression that represents the sum of b and 5 times 2 is written as b + (5 × 2). The parentheses indicate that the multiplication should be done first, resulting in 5 times 2, which equals 10. Then, you add the value of b to this result. Therefore, the complete expression evaluates to b + 10.

It is important to understand the role of parentheses in mathematical expressions. Parentheses define the order of operations, ensuring that operations inside them are carried out first. Without the proper use of parentheses, expressions can yield different results.

The expression written in 4 simplified multiplication is

The correct answer is option C. (−2, −6). Hence the correct option is c.

Given the original point is (−2, 6), let's denote it as (x, y).

Identify the original point.

The original point is (−2, 6), where x = −2 and y = 6.

Reflect the point across the x-axis.

To reflect the point across the x-axis, we keep the x-coordinate the same and change the sign of the y-coordinate. This means that if the original y-coordinate is positive, it becomes negative, and if it's negative, it becomes positive.

So, for the reflected point:

[tex]\[ x_{\text{reflected}} = x_{\text{original}} = -2 \]\[ y_{\text{reflected}} = -y_{\text{original}} = -6 \][/tex]

Determine the coordinates of the reflected point.

So, the coordinates of the reflected point are (−2, −6).

Therefore, the correct answer is option C. (−2, −6). Hence the correct option is c.

Complete question:

The coordinates of a point on a coordinate grid are (−2, 6). The point is reflected across the x-axis to obtain a new point. The coordinates of the reflected point are A.(2, 6) B.(−2, 6) C. (−2, −6) D. (2, −6)

We can use the points (-2, 5) and (2, 0) to solve.

To solve the problem '15 divided by 1 2/3', change the mixed number to an improper fraction, then multiply by the reciprocal. The answer to the operation is 9.

The student's question is about division in Mathematics, specifically, 'What is the answer to 15 divided by 1 2/3?' To solve this division problem, one needs to remember to change the mixed number to an improper fraction. 1 2/3 is equivalent to 5/3. Then, to divide, we multiply by the reciprocal. The reciprocal of 5/3 is 3/5. Thus, the division operation 15 ÷ 1 2/3 turns into the multiplication operation 15 x 3/5.

Now, simplify by multiplying the two numbers: 15 x 3/5 = 9. So, 15 divided by 1 2/3 equals 9.

Answer:

[tex]26\frac{1}{5}[/tex] miles.

Step-by-step explanation:

We have been given that there are 26.2 miles in a marathon. We are asked to find the number of miles using a mixed number in simplest form.

First of all, we will convert our given number as a fraction by multiplying and dividing by 10 as:

[tex]26.2\times\frac{10}{10}=\frac{262}{10}[/tex]

[tex]\frac{262}{10}=26\frac{2}{10}[/tex]

[tex]26\frac{2*1}{2*5}[/tex]

[tex]26\frac{1}{5}[/tex]

Therefore, the number of miles in mixed number would be [tex]26\frac{1}{5}[/tex] miles.

Answer

25%

Explanation

We know that original price of the jeans is $39.99 and the discount is $10, so we need to find what percentage of $39.99 is $10. To do it we can set up a proportion:

[tex]\frac{39.99---->100}{10---->x}[/tex]

Now we can express our proportion as a fraction and solve for [tex]x[/tex]:

[tex]\frac{39.99}{10}= \frac{100}{x}[/tex]

[tex]x=\frac{10*100}{39.99}[/tex]

[tex]x=25[/tex]

We can conclude that the percent of the discount to the nearest percent is 25%

Answer

6.5%

Explanation

Since the sales taxes is applied to the subtotal, this time we need to find what percentage of 29.99 is 1.95. To do it, we are going to set up a proportion, just like before:

[tex]\frac{29.99---->100}{1.95---->x}[/tex]

Now we can express our proportion as a fraction and solve for [tex]x[/tex]:

[tex]\frac{29.99}{1.95}= \frac{100}{x}[/tex]

[tex]x=\frac{1.95*100}{29.99}[/tex]

[tex]x=6.5[/tex]

We can conclude that the percent of sales tax to the nearest tenth of a percent is 6.5%

Answer

20%

Explanation

First, we need to find the cost of the Jeans; to do it, we are using the markup formula:

[tex]markup=(\frac{price-cost}{cost} )100[/tex]

We know that the price of the Jeans is $39.99 and the markup is 66%, so let's replace those values in our formula:

[tex]60=(\frac{39.99-cost}{cost} )100[/tex]

[tex]\frac{60}{100} =\frac{39.99-cost}{cost}[/tex]

[tex]0.6=\frac{39.99-cost}{cost}[/tex]

[tex]0.6cost=39.99-cost[/tex]

[tex]0.6cost+cost=39.99[/tex]

[tex]1.6cost=39.99[/tex]

[tex]cost=\frac{39.99}{1.6}[/tex]

[tex]cost=24.99[/tex]

Now that we have the cost now, we just need to use the markup formula again but this time using the price after discount ($29.99).

[tex]markup=(\frac{price-cost}{cost} )100[/tex]

[tex]markup=(\frac{29.99-24.99}{24.99} )100[/tex]

[tex]markup=(\frac{5}{24.99} )100[/tex]

[tex]markup=20[/tex]

We can conclude that the percentage of markup after the discount is 20%

No, Colin is not correct. Katy requires 19 minutes to reach the sea floor.

What is Speed?

Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

Total distance between sea level and sea floor is 104 feet.

Katy is available 28 feet below sea level.

so, remaining distance katy needs to  move = 104 - 28 feet

                                                                         = 76 feet

Speed of Katy for moving downwards = 4 feet per minute

Time taken by Katy to reach sea floor = [tex]\frac{distance}{speed}[/tex]

                                                               = 76/4

                                                               = 19 minutes

Thus, Katy requires 19 minutes to reach the sea floor.

First, change to improper fractions by:

8×6=48

48+5=53 ---- this becomes new numerator

536

so

856 = 536 feet

Do the same for the other fractions.

812 = 172 feet

2413 = 733 feet

536+172 = height of two stories, excluding the attic

Let x = height of attic

x = 733 - (536+172)

Change to similar fractions by getting LCD=6

x = 733(22) - (536+172(33))

x=1466−(536+516)

x=1466−1046

x=426

x=7

To simplify the expression, we calculate each part separately. Then, we multiply the numerator and simplify the denominator. Finally, we cube the expression by multiplying it by itself three times.

To simplify the expression 2 to the power of 2 multiplied by 6 to the power of 0 whole over 7, the whole cubed, we need to calculate each part of the expression.

First, 2 to the power of 2 is 2 * 2 = 4.

Next, 6 to the power of 0 is 1, because any number raised to the power of 0 is always 1.

Now, we have 4 * 1 whole over 7. To simplify this, we can multiply the numerator and simplify the denominator. So the expression becomes 4 whole over 7 cubed.

To cube the expression, we need to multiply 4 by itself three times. So 4 * 4 * 4 = 64. Therefore, 4 whole over 7 cubed simplifies to 64.

By multiplying the fractions 3/5, 4/7, and 1/3, which represent the boys, sixth graders, and runners respectively, we find that 4/35 of the track team are sixth-grade boy runners.

To find the fraction of the track team that consists of sixth-grade boy runners, we'll need to multiply three fractions that represent different parts of the team:

The fraction of the team that are boys: 3/5

The fraction of these boys that are sixth graders: 4/7

The fraction of the sixth-grade boys that are runners: 1/3

Now, multiplying these numbers expressing common fractions gives us:

(3/5) × (4/7) × (1/3) = 12/105 = 4/35.

So, 4/35 of the track team are sixth-grade boy runners.
