To get the answer, you need to solve the equation for x = 7.

f(7) = 3/7 + 2 - sqrt(7) - 3.

= 3/7 - 1 - sqrt(7).

If you need to simplify it further:

= -4/7 - sqrt(7).

If you need it in decimal form:  = -3.2171798824

Answer:

f(7)=-3.217

Step-by-step explanation:

We are given that [tex]f(x)=\frac{3}{x}-\sqrtx-3[/tex]

We have to find the value of f(7).

Substitute the value of x=7

Then, we get

[tex]f(7)=\frac{3}{7}+2-\sqrt7-3=\frac{3}{7}-1-\sqrt7[/tex]

[tex]f(7)=\frac{3-7}{7}-\sqrt7=-\frac{4}{3}-\sqrt7[/tex]

[tex]f(7)=-\frac{4}{7}-2.646[/tex]

Because [tex]\sqrt7=2.646[/tex]

[tex]f(7)=-\frac{4+18.522}{7}=-\frac{22.522}{7}[/tex]

[tex]f(7)=-3.217[/tex]

Hence, f(7)=-3.217

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.

3452 divide 2 multiply by 3 is 5178

Step-by-step explanation:

Since we have given that

Number of miles round trip to Craigs aunts house = 3452 miles

Number of times he travels to her house this year = 3

So, we need to find the number of miles he travel in all.

So, the number of miles he travel in all is given by

[tex]3\times 3452\\\\=10,356\ miles[/tex]

Hence, there are 10,356 miles in all he traveled.

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.

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

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.

To write 2.96 as a mixed number or fraction in simplest form, we divide the decimal part by 100, convert it to a fraction, and simplify it. The final answer is 2 24/25.

To write 2.96 as a mixed number or fraction in simplest form, we first need to understand that 2.96 is a decimal number. The whole number part is 2 and the decimal part is 0.96. To convert the decimal part to a fraction, we take the decimal part as the numerator and 100 as the denominator. So, 0.96 becomes 96/100. Now, we can write the mixed number as 2 96/100. To simplify this fraction, we divide both the numerator and the denominator by their greatest common factor, which is 4. Dividing 96 by 4 gives us 24, and dividing 100 by 4 gives us 25. So, the simplest form of 2 96/100 is 2 24/25.

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

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:

Jim reached a greater depth by one foot, as he started 12 feet below the surface.

Step-by-step explanation:

Jim

12 feet+17 feet = 29

29-3 feet (rose 3 feet) = 26

26+8= 34 feet

Carla

0 feet (surface)+ 19 feet= 19

19-3 feet= 16

16+17= 33 feet

After performing the depth calculations for both Jim and Carla's scuba diving, it was found that Carla is resting at a greater depth than Jim. Jim ended 24 feet below the surface, and Carla ended 33 feet below the surface.

To start with, let's calculate how deep Jim and Carla each ended their dives. We begin with Jim, who started 12 feet below the surface, descended 17 feet, went up 3 feet and then descended another 8 feet. His total depth is therefore 12 - 17 + 3 - 8 = 24 feet below the surface.

Now let's calculate Carla's depth. Carla started at the surface (0 feet below), then descended 19 feet, ascended 3 feet, and descended another 17 feet. Her total depth is therefore 0 - 19 + 3 - 17 = 33 feet below the surface.

Comparing these two figures, Carla is resting at a greater depth than Jim.
