Without computing each sum find which is greater O or E and by how much O=3+5+7+9+....+98 E=2+4+6+8+....+98

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)

Answer: A

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.

I am so sorry for giving you the wrong answer at first.

Here's the processs

1x=-0.5555

Move the decimal point in the repeating decimal one space forward

10x=-5.55555

Then subtract

10x=5.5555

x=-0.5555= 9x=-5

Divide both sides by 9

9x=-5

9x/9=-5/9

-5/9 is your final answer!

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:

[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.

landon has 60 peppermints and 90 candy corns. he wants to make packages of these candies to bring to his school

the maximum number of packages we take GCF

GCF gives the maximum number of grouping

WE find GCF of 60  and 90

1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 are the factors of 60

1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90 are the factors of 90

So greatest common factor is 30

Hence , 30 packages he can make so that there are no candies left over

Final answer:

To find out the maximum number of packages Landon can make, we calculate the greatest common divisor of 60 and 90, which is 30. Thus, Landon can create 30 packages of candies with none left over.

Explanation:

Landon has 60 peppermints and 90 candy corns. He wants to create packages so that there are no candies left over. To determine the maximum number of packages Landon can make without any leftovers, we need to find the greatest common divisor (GCD) of 60 and 90, which is the largest number that divides both without leaving a remainder.

Step 1: List the factors of each number.
Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Factors of 90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

Step 2: Identify the common factors.
Common factors of 60 and 90: 1, 2, 3, 5, 6, 10, 15, 30

Step 3: Find the greatest common factor.
The greatest common factor is 30.

Therefore, Landon can make a maximum of 30 packages of candies to bring to school without any candies left over.

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.

Given condition is:

A sloth moves in one hour = [tex]\frac{250}{5/8}[/tex]

[tex]\frac{5}{8}=0.625[/tex]

So, a sloth moves in one hour = [tex]\frac{250}{0.625}=400 units[/tex]

Hence, in 60 minutes a sloth moves = 400

In 1 minute sloth will move = [tex]\frac{400}{60}[/tex]

In 90 minutes it will  move = [tex]\frac{400}{60}\times90=600[/tex]

The answer is 600 units.

Answer:

A sloth can move 600 units in 90 minutes.

Step-by-step explanation:

The problem says that if you divide 250 in [tex]\frac{5}{8}[/tex] you obtain how far a sloth move in one hour, then:

[tex]250:\frac{5}{8}=\frac{250.8}{5}= \frac{2000}{5}=400[/tex]

A sloth moves 400 units in one hour (60 minutes).

We can use a rule of three,

400 units ⇒ 60 minutes

x               ⇒ 90 minutes

[tex]x=\frac{90.400}{60} \\\\x=\frac{36000}{60}\\\\x=600[/tex]

A sloth can move 600 units in 90 minutes.

The least common denominator of 5/6 and 3/10 is 30.

Answer:

35 + 7x

Step-by-step explanation:

You cannot solve it because there is no equal sign. This is not an equation. This is just an expression, so you can simplify it, but not solve it. To simplify it, use the distributive property to multiply out the 5 by what is inside the parentheses.

7(5 + x) = 7 * 5 + 7 * x = 35 + 7x

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.

complementary angles are angles whose measures equals 90° when added. so to find the measure of this angle, we subtract 25° from 90°. the measure of the angle is 65°.

65°

complementary angles have a sum of 90°

angle = 90° - 25° = 65°

Answer:

The tip is $3.92. The total bill is $23.54.

Step-by-step explanation:

I simply used a calculator to find the answer. It's just basic multiplication for the tip and addition for the total bill.

Answer:

1st blank = $4

2nd blank = $24

Step-by-step explanation:

Henri's bill at a restaurant is $19.62. He wants to leave a tip of 20%

Estimated round off of $19.62 is $20.

Estimations are made for easy calculations in mind, this is why we round to nearest 0.

So, 20% of $20 is :

[tex]0.20\times20=4[/tex] dollars

And the total bill, including the tip is estimated to be :

= [tex]20+4=24[/tex] dollars

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:

 the initial height of ball when the player releases it

Step-by-step explanation:

A basketball player shoots a free throw in a game. The quadratic expression models the height of the ball, in feet, where t is the time, in seconds.

y= -16t^2 + 25t+7

Given equation is in the form of

y= -16x^2 + V t + h

Where V  represents the initial velocity and h represents the initial height of the ball

Now we compare our equation with the general equation

We have 7 in the place of h

So , 7 is the initial height of the ball

Answer is 7 is  the initial height of ball when the player releases it

Step-by-step explanation:

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

1800-720=1080

He has 1080 miles left, he'll run 6 days per day so 1080/6=180

He won't need more than 180 days

Answer:

Step-by-step explanation:

Write and solve an inequality for d, the # of days:

720 mi + (6 mi / day)d ≥ 1800 mi.  Then:

(6 mi/day)d ≥ 1800 mi - 720 mi, or (6 mi/day)d ≥ 1080 mi.

Solving for d, we get 1080/6 days:  180 days.  If he runs 6 miles per day for 180 days, he will have covered 1800 miles.  His running more days will, of course, increase the total number of miles covered.
