We need to find how many ways can the team choose one captain and then two assistants.

What is the formula to find the permutation?

The formula to find the permutation is [tex]nP_{r} =\frac{n!}{(n-r)!}[/tex].

Now, [tex]10P_{3} =\frac{10!}{(10-3)!}[/tex]

=10×9×8×7!/7!=720

Therefore, one captain and then two assistants can be chosen in 720 ways.

Answer:

  positive

Step-by-step explanation:

The exponent 12 tells you how many times (-1 3/4) is a factor in the product. The number 12 is even, so there will be an even number of minus signs in the product. That results in a positive product.

What are the coordinates of the point on the directed line segment from (-7, 10) to
(-2,-5) that partitions the segment into a ratio of 2 to 3?

Answers

line segment from (-10,-3) to (1,7)
a ratio of 2 to 3 means that the line segment is divided into 5 equal pieces
let (x,y) be 2/5 of the way from (-10,-3) to (1,7)
what is the distance of the segment ?
use the distance formula to find the distance of the segment
√(11^2+10^2)=√221
-10 to 1 is 11 units, 2/5(11)=4.4
-3 to 7 is 10 units, 2/5(10)=4
-10+4.4=-5.6
-3+4=1
the point is (-5.6,1)
check:
find the distance from (-10,-3) to (-5.6,1)
find the distance from (-5.6,1) to (1,7)
these distances should add up to √221
first distance:√[(4.4^2)+4^2]=√35.36
second distance:√[(6.6^2)+6^2]=√79.56
√35.56+√79.56=√221
5.946+8.919=14.866
14.865≈14.866

PLZZ HELPP

Answers

Answer:

[tex]Day\ 3 = 1\frac{3}{12}[/tex]

Step-by-step explanation:

Given

[tex]Total = 2ft[/tex]

[tex]Day\ 1 = \frac{1}{6}[/tex]

[tex]Day\ 2 = \frac{7}{12}[/tex]

Required

Determine the amount of snow on day 3

This can be calculated using:

[tex]Day\ 1 + Day\ 2 + Day\ 3 = Total[/tex]

Substitute values for the known parameters

[tex]\frac{1}{6} + \frac{7}{12} + Day\ 3 = 2[/tex]

Collect Like Terms

[tex]Day\ 3 = 2 - \frac{1}{6} - \frac{7}{12}[/tex]

Take LCM

[tex]Day\ 3 = \frac{24 - 2 - 7}{12}[/tex]

[tex]Day\ 3 = \frac{15}{12}[/tex]

Express as mixed number

[tex]Day\ 3 = 1\frac{3}{12}[/tex]

Which expression represents the sum of n and 7 multiplied by 3? *
1. n + 7 x 3
2. (n + 7) x 3
3. (n + 7) ÷ 3
4. (n - 7) x 3

Answers

Answer:

Step-by-step explanation:

(n+7)×3

Answer:

1.  n + 7×3

Step-by-step explanation:

The sum of n and 7 multiplied by 3:

n + 7×3

It is option 1

This is a tricky one but when reading carefully we see there is nothing that adds n to 7 before multiplying by 3, therefore it reads as n plus ( 7 multiplied by 3).

solve and graph 3t - 12 < -9

Answers

Answer:

x = anything lower than 1

Step-by-step explanation:

x < 1

The constraint of inequality 3t - 12 < -9 is t < 1 and has been plotted on a number line.

What is inequality?

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Given the inequality

3t - 12 < -9

Add 12 on both sides

3t - 12 + 12 < -9 + 12

3t < 3

Divide by 3 into both sides

t < 1

Hence "The constraint of inequality 3t - 12 < -9 is t < 1".

Step-by-step explanation:

Ivy says:

f(1) = -100

f(n) = -100 + 50( n - 1 )f(1) = -100 + 50( 1 - 1 )f(n) = -100 + 50(0 ) anything times 0 is 0!f(1) = -100

You do that with the other numbers in the sequence. 2 = -50, 3 = 0 and so on

When you to n as 1, 2, and 3 they seem to all check out. So Ivy is right!

Andrey says:

f(1) = -100f(1)= -150 +50(1)f(1) = -150 + 50f(1) = -100

That's a little suspicious don't you think that both answers are right..

Essentially they are both the same equation!

So let's simplify Ivy's equation!

f(n) = -100 + 50( n - 1 )

f(n) = -100 + 50n - 50

f(n)= -150 +50n

Which is basically Andrey's equation and they both seem to be right for the sequence! So both of them are right!

Find the product of (1)(3)(x).
Your
answer

Answers

Answer:

2/5.

Step-by-step explanation:Start with fractions for which you need to find the product. In this example, we will multiply the fractions 4/6 and 3/5.

Simplify the fractions to the lowest terms. A fraction needs to be simplified if the same number can divide both the numerator and denominator of a fraction. So 4/6 would become 2/3 and you would multiply by 3/5.

Multiply the numerators. Multiply the top number in one fraction by the top number in the other fraction. In this case 2 x 3 = 6.

Multiply the denominators. Multiply the bottom number of one fraction by the bottom number in the other fraction. In this case 3 x 5 = 15

Simplify the product again if necessary. Your product of 6/15 can be converted into 2/5 by dividing both the numerator and denominator by 3. So the product of 4/6 and 3/5

Answer:

£ 268.2

Step-by-step explanation:

495(1/3)+124(0.5)+(495(2/3)-124)(0.2)=165+62+41.2

                                                            =268.2

Answer: £268.20

Step-by-step explanation:

1/3 of 495 is 165.

124 x .50 = 62.

165 + 124 = 289

495 - 289 = 206

206 x .20 = 41.20

165 + 62 + 41.20 = 268.20

The distance a vehicle travels can be found by using the formula d = rt, where d is the total distance traveled, r is the rate of speed, and t is the amount of time spent traveling. Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour. To the nearest hour, how many hours does she spend driving?

Answers

Answer:

She spends 2 hours driving.

Step-by-step explanation:

The formula given is:

[tex]d = rt[/tex]

In which d is the distance traveled, r is the rate of speed, and t is the amount of time spent traveling.

Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour.

This means that [tex]d = 80, r = 50[/tex]

To the nearest hour, how many hours does she spend driving?

We have to find t. So

[tex]d = rt[/tex]

[tex]50t = 80[/tex]

[tex]t = \frac{80}{50}[/tex]

[tex]t = 1.6[/tex]

Rounding to the nearest hour

She spends 2 hours driving.
