how many craft sticks will be left over if 9 friends equally share a package of 85 craft sticks

Answer:3.55 , 71/20

Step-by-step explanation:

The 6th term of this sequence is 360

From the question, we have the following parameters that can be used in our computation:

Sequence representation = 2n² × 5

This means that

nth term = 2n² × 5

So, we have

f(n) =  2n² × 5

For the 6th term, the value of n is 6

i.e. n = 6

Substitute the known values in the above equation, so, we have the following representation

f(6) =  2(6)² × 5

Evaluate

f(6) =  360

Hence, the 6th term s 360

Answer:

a = 7

Step-by-step explanation:

Substitute x for 2 and f(x) for 14

14 = -2(2³) + a(2²) + 2

14 = -16 + 4a + 2

14 = -14 + 4a

14 + 14 = 4a

28 = 4a

4a = 28

Divide both sides by 4

4a/4 = 28/4

a = 7

Alternative:

Since from the question, you're already told that f(2) = 14, you just have to find the number that can be multiplied by 2 with a resultant of 14; that number is 7. To confirm, substitute a for 7 in the equation.

Answer:

x = - 10

Step-by-step explanation:

2(x + 3) = x - 4

==> distribute the 2

2x + 6 = x - 4

==> subtract 6 from both sides

2x = x - 10

==> subtract x from both sides

x = - 10

The potential outliers, given the normal annual precipitation in the different U.S. cities are E. 59.4; 65.3.

Outliers in a data distribution are values or data points that are far from the other points in the data. These can be statistically significant when they distort measures of central tendency such as mean.

In this case, the potential outliers in the normal annual precipitation 59.4 and 65.3 because they are far from the highest annual precipitation (before them) of 47.2 inches. 9.2 inches is quite low but it is close to 12.3 inches and 13.6 inches and so is not an outlier.

Valentina is trying to decide whether to join her school's swim team. During the summer, the team practices 4 days per week. Each of those days, they practice for 3 hours in the morning and practice again in the afternoon. They practice for a total of 20 hours each week.

Which equation can you use to find h, the length of each afternoon practice in hours?

Summer swim practice is 4 days per week. Each day has 3 hours of morning practice and h hours of afternoon practice. So, the number of hours of practice each day is h+3. Weekly practice is a total of 20 hours. This equation represents the situation.

4 (h+3)

=

20

days of practice per week

hours of practice each day

total hours of practice each week

The equation 4(h+3)=20 can be used to find the length of each afternoon practice in hours. Solve the equation for h.

4(h+3)

= 20

h+3

= 5 Divide both sides by 4

h

= 2 Subtract 3 from both sides

Each afternoon practice is 2 hours.

The value g(7) of the function g(x) = 7  / 8 x  - 1 / 2 is 45 / 8.

A function relates each element of a set with exactly one element of another set (possibly the same set).

In a simpler term, a function relates an input to an output.

Therefore, let's find the value of g(7) for the function below:

g(x) = 7  / 8 x  - 1 / 2

Hence,

g(7) = 7 / 8 (7)  - 1 / 2

g(7) = 49 / 8  - 1 / 2

g(7) =  49 - 4 / 8

Therefore,

The total distance of the triathlon is 12000 m.

Two or more expressions with an equal sign are defined as an equation.

Let the total distance of the triathlon be x.

Tasneem swims 1/4of the total route, therefore, she swims for a distance of S = (1/4)x.

Now the remaining route is,

x - (1/4)x

=3/4x

After swimming, she cycles 3/5 of the remaining route, therefore, she cycles for a distance of C = (3/5)×(3/4)x,

C = (9/20)x

Now, she runs for the rest of the route, therefore, she runs for a distance of R = x - (1/4)x-(9/20)x

Or, R = (20x - 5x - 9x)/20

R = (6x)/20

Given that Tasneem runs 3600 m, therefore, substitute R = 3600 into the above equation,

3600 = (6x)/20

(3600×20)/6 = x

12000 = x

Therefore, the total distance of the triathlon is 12000 m.

Since both fractions already have a common denominator ( [tex]\frac{n}{100}[/tex] ), we can simply subtract the two to find how much greater the fractional part of North America is than the fractional part of Europe:

The rate of spray at both times is 40 gallons/hour and it is the same.

What is the rate of change?

How quickly something changes over time is referred to as its rate of change, or ROC. Thus, it is the acceleration or deceleration of changes (i.e., the rate) rather than the magnitude of individual changes.

We have,

spray 20 gallons of water in 1/2 hour.

30 gallons and 3/4 hours (it's not 347 hours).

We simply calculate the rate for one hour:

1/2 hour = 20 gallons

3/4 hours = 30 gallons

Then for 1 hour,

1 hour = 20 * 2 = 40 gallons

1 hour = 30 * 4/3 = 40 gallons

Hence, the rate of spray at both times is 40 gallons/hour and it is the same.

The number of pounds of grapes sold is 17 pounds and the number of pounds of apples sold is 47 pounds.

According to the question,

We have the following information:

Cost of 1 pound of grapes = $3.75

Cost of 1 pound of apples = $4

Total cost made by selling = $251.75

And the weight of the apples and grapes sold = 64

Now, let's take the weight of grapes to be x pounds and the weight of apples to be y pounds.

So, we have:

x+y = 64

x = 64-y ....(1)

3.75x+4y = 251.75

Putting the value of x in this equation:

3.75(64-y)+4y = 251.75

3.75*64-3.75y+4y = 251.75

240+0.25y = 251.75

0.25y = 251.75-240

0.25y = 11.75

y = 11.75/0.25

y = 47 pounds

Now, putting this value of y in equation 1:

x = 64-y

x = 64-47

x = 17 pounds

Hence, the number of pounds of grapes sold is 17 pounds and the number of pounds of apples sold is 47 pounds.

Let

x + y = 48

29x + 51y = 50*48

x + y = 48

29x + 51y = 2400

Solve simultaneously

From (1)

x = 48 - y

Substitute into (2)

29x + 51y = 2400

29(48 - y) + 51y = 2400

1392 - 29y + 51y = 2400

- 29y + 51y = 2400 - 1392

22y = 1008

y = 1008/22

y = 45.82 pounds

Substitute y = 45.82 pounds into (1)

x + y = 48

x + 45.82 = 48

x = 48 - 45.82

x = 2.18 pounds

So therefore, the number of pounds of 29% alloy and 51% alloy is 45.82 pounds and 2.18 pounds respectively.
