Answer:

after 13 hours

Step-by-step explanation:

Since the monthly fee is $4.25

so

● $4.25 + ( 2.75 × Number of hours) = 40

● ( 2.75 × Number of hours) = $40 - $4.25

● 35.75/ 2.75 = 13

Answer:

63°

Step-by-step explanation:

Angle sum property = 180°

=> 19 + 98 + x = 180

=> x = 180 - 117 = 63°

Answer:

Step-by-step explanation:

Given,

Measurement of one angle of a triangle = 19°

Measurement of 2nd angle of the triangle = 98°

Let,

The third angle be = x

As we know,

Sum of all the angles of a triangle is 180°

Therefore,

By the problem,

=> 19° + 98° + x = 180°

=> x = 180 - 98 - 19

=> x = 63

Hence,

The measurement of 5he third angle of the triangle is 63° (Ans)

Answer:

Step-by-step explanation:

To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. For example, lets find the intercepts of the equation y = 3 x − 1 \displaystyle y=3x - 1 y=3x−1. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

1.To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.

2.To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

3.To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

Answer:

8x + 4y

Step-by-step explanation:

3(x + y) + 5x + y

3x + 3y + 5x + y....... distribute 3 to both variables in the parenthesis

8x + 4y....................... combine like terms

Answer

8x+4y

Step-by-step explanation:

First you expand the 3(x+y) by multiplying 3 with x+y

So it becomes 3x+3y

Now your new expression will be 3x+3y+5x+y

After that, you combine the like terms, 3x and 5x are like terms, 3y and y are like terms.

So it will become 3x+5x+3y+y

You can add the like terms up, so 3x+5x=8x and 3y+y =4y

The simplified expression will be 8x+4y

Answer:

....................... what is the queston

Step-by-step explanation:

If Athlete J continues at that speed, it will take 12 minutes to run 1 mile

It will take Athlete J 60 minutes to run 5miles

Since the speed of Athlete H is greater than that of J, hence Athlete H runs faster.

The formula for calculating the speed of the athlete is expressed as:

Speed = Distance/Time

1) If Athlete J runs 2/3 of a mile in 8 minutes, this can be expressed as:

2/3 miles = 8 minutes

If the athlete runs for 1 mile, then;

1 mile = x

Divide both expressions

2/3 = 8/x

2x = 24

x = 12 minutes

Hence If Athlete J continues at that speed, it will take 12 minutes to run 1 mile

2) if athlete J run 5 miles, the time taken will be expressed as;

2/3(5) = 8/x

2/15 = 8/x

2x = 120

x = 60minutes

Hence it will take Athlete J 60 minutes to run 5miles

3) If Athlete H runs 2 3/4 miles in 1/2 hour, then the speed of athlete H will be expressed as:

Speed = (2 3/4)/0.5

Speed = 2.75/0.5

Speed = 5.5miles/hr

For Athlete J;

Speed = 5/1

Speed = 5 miles/hr

Since the speed of Athlete H is greater than that of J, hence Athlete H runs faster.

The given quadratic function for the restaurant sales indicates that the sale first reduces then increases.

Reasons:

The function for the sales in the restaurant is y = 3·x² + 3.2·x + 514

Where;

y = Sales in billions of dollars

x = Number of years since 2008

Required:

The year in which the restaurant industry food and drink sales will be $1212 billion.

Solution:

When the food and drink sale is $1212 billion, we have;

1212 = 3·x² + 3.2·x + 514

Which gives;

3·x² + 3.2·x + 514 - 1212 = 0

3·x² + 3.2·x - 698 = 0

Factorizing with a graphing calculator gives;

(x + 15.796)·(x - 14.729) = 0

x = -15.796, or x = 14.729

The time will have a natural number value, therefore the positive value of x

= 14.729 is used.

Therefore, the number years since 2008 at which the restaurant sales will

be $1212 billion is approximately 15 years.

The year at which the sales will be $1212 billion = 2008 + 15 = 2023

Answer: 8

Step-by-step explanation:

Rewriting input as fractions if necessary:

1/8, 1/4

For the denominators (8, 4) the least common multiple (LCM) is 8.

LCM(8, 4)

Therefore, the least common denominator (LCD) is 8.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 1/1 = 1/8

1/4 = 1/4 × 2/2 = 2/8

Answer: 10%

Step-by-step explanation:

Answer:

Step-by-step explanation:

To solve this, what you first should do is make one of the variables equal, that way you can eliminate that variable and only have to solve one of them. Let's eliminate y, since that one is easier. As you can see, the y in the first equation is 3 times less than the y in the second, so you would multiply everything the first equation by 3 to help eliminate y. After doing this, you would have -6x + 3y = 48, with which you will add to the second equation, which leaves you with -10x = 50. Since you have a negative x, multiplying both sides by a negative sign will make it much easier to find x's value, which gives you -5 as x's value, so x = -5. Now keep this aside, because it will help you solve.

     Now that you have the value of x (-5), you should replace one of the equations with x's value, so let's just do this to the second equation. Now you have 20 - 3y = 2. Here, you should take the 20 to the right side to isolate 3y from the numbers, which leaves you with -3y = -18. This gives tells you, after simplifying, that y = 6.

     And since the order pair is always (x,y), your answer would be (-5, 6). STILL EDITING ANSWER!
