Answer:

42

Step-by-step explanation:

45-3

Answer:

11.25, or 42

Step-by-step explanation:

If 3 miles every practice too, then:

3+1 = 4

45/4 = 11.25

If 3 miles already, then always 1 mile:

45 - 3 = 42

42/1 = 42

Answer:

Step-by-step explanation:

3*1/10 = 30/10 = 3

3 * 10 = 30

As you can see, 3 is less than 30.

Best of Luck!

The expression 3x1/10 is less than 3x10 because, 1-tenth is less than 10.

According to the question;

In essence, since 3 is common to both expressions;

Ultimately, since 1/10 is less than 10; we can conclude that 3×1/10 is less than 3×10.

Answer:

$171

Step-by-step explanation:

A store has a 10% off sale on pants. With this discount, the price of one pair of pants before tax is $17.10 What was the original price of the pants?

Let x represent the original price of the pair of pants

From the question, we know that:

10% of x = $17.10

10/100 × x = $17.10

10x/100 = $17.10

Cross Multiply

10x = 100 × $17.10

10x = 1710

x = 1710/10

x = $171

Hence, the original price of the pants = $171

Answer:

15.17in of fabric on headbands

9.31 in of fabric on wristbands.

Step-by-step explanation:

Step one:

given data

the total amount of person players plus coaches= 33+3= 36

for each person, she uses = 546.12/36= 15.17 in of fabric on headbands

She also uses 307.23 inches of fabric on wristbands for just the players

For each player, she will use= 307.23/33= 9.31 in of fabric

Hence for each player, she used

15.17in of fabric on headbands

9.31 in of fabric on wristbands

Answer:

240 feet per hour

Step-by-step explanation:

Given that:

Submarine is descending for examining the sea floor.

Distance of sea floor from the surface = 2100 feet

Time taken for the descend = 8.75 hours

To find:

The rate of descent in feet per hour = ?

Solution:

Here, we are given the distance traveled in feet and the time taken to travel that distance in hours.

And we have to find nothing but the speed of the submarine.

First of all, let us have a look at the relationship among speed, distance and time.

[tex]Speed = \dfrac{Distance}{Time}[/tex]

Putting the values of distance and time.

[tex]Speed = \dfrac{2100}{8.75}\\\Rightarrow Speed = \bold{240\ feet/hr}[/tex]

Answer:

2 times

Step-by-step explanation:

The probability of 1/3 means that the spinner will land on a 2, 1/3 of the time:

We can predict how many times it will land on a 2 by finding 1/3 of 6:

6/3

= 2

So, the spinner will land on a 2, two times

Number of times probability of landing on a 2 is 2, when you spin the spinner 6 times.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, in a game, the probability that a spinner will land on a 2 is 1/3.

If you spin the spinner 6 times, probability of landing on a 2 is

1/3 ×6

= 2

Therefore, number of times probability of landing on a 2 is 2.

Answer:

[tex]10(\cos 75^\circ+\mathbf{i}\sin 75^\circ)[/tex]

Step-by-step explanation:

Complex Numbers

Complex numbers can be expressed in several forms. One of them is the rectangular form(x,y):

[tex]Z = x+\mathbf{i}y[/tex]

Where

[tex]\mathbf{i}=\sqrt{-1}[/tex]

They can also be expressed in polar form (r,θ):

[tex]Z=r(\cos\theta+\mathbf{i}\sin\theta)[/tex]

The polar form is also shortened to:

[tex]Z = r CiS(\theta)[/tex]

The product of two complex numbers in polar form is:

[tex][r_1Cis(\theta_1)]\cdot [r_2Cis(\theta_2)]=r_1\cdot r_2Cis(\theta_1+\theta_2)[/tex]

We are given the complex numbers:

2(cos(45°) + i sin(45°)) and 5(cos(30°) + i sin(30°))

They can be written as:

2CiS(45°) and 5CiS(30°). The product is:

2CiS(45°) * 5CiS(30°) = 10CiS(75°)

Expressing back in rectangular form:

[tex]\boxed{2CiS(45^\circ) \cdot 5CiS(30^\circ) =10(\cos 75^\circ+\mathbf{i}\sin 75^\circ)}[/tex]

Answer:

The solution of the system of equations be:

[tex]x=8,\:y=4[/tex]

Hence, option C is true.

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}4x+7y=60\\ -4x+7y=-4\end{bmatrix}[/tex]

adding both the equations

[tex]-4x+7y=-4[/tex]

[tex]+[/tex]

[tex]\underline{4x+7y=60}[/tex]

[tex]14y=56[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}4x+7y=60\\ 14y=56\end{bmatrix}[/tex]

solve 14y for y

[tex]14y=56[/tex]

Divide both sides by 14

[tex]\frac{14y}{14}=\frac{56}{14}[/tex]

Simplify

[tex]y=4[/tex]

[tex]\mathrm{For\:}4x+7y=60\mathrm{\:plug\:in\:}y=4[/tex]

[tex]4x+7\cdot \:4=60[/tex]

[tex]4x+28=60[/tex]

Subtract 28 from both sides

[tex]4x+28-28=60-28[/tex]

Simplify

[tex]4x=32[/tex]

Divide both sides by 4

[tex]\frac{4x}{4}=\frac{32}{4}[/tex]

[tex]x=8[/tex]

Therefore, the solution of the system of equations be:

[tex]x=8,\:y=4[/tex]

Hence, option C is true.

[tex]b = \$7[/tex]

Step-by-step explanation:

Given that:

Cost of book that Tyler wants to buy for his school = $13

He wants to buy books for his sisters as well.

Total amount of money present with Tyler = $27

Money to be spent on books for his sisters is same and is represented as [tex]b[/tex].

To find:

The value of [tex]b[/tex].

Solution:

As per question statement, the sum of all the books bought must be equal to $27.

The sum of money spent on all the books = Cost of Tyler's book + Cost of books for his sisters

[tex]\Rightarrow \$13 + b + b = \$27\\\Rightarrow \$13 + 2b = \$27\\\Rightarrow 2b =\$14\\\Rightarrow b =\$7[/tex]

Therefore, Tyler must spend $7 on each of her sister's books.

Note: The first point of the table should be (-2,-1) instead of (-1,-2). because (-1,-2) does not satisfy the relation.

Given:

Consider the table of values is

x      y

-2     -1

0     3

1      5

3     9

To find:

The equation that best describes the  relationship between the corresponding values of x and y.

Solution:

Consider any two points from the given table, i.e., (0,3) amd (1,5).

So, the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-3=\dfrac{5-3}{1-0}(x-0)[/tex]

[tex]y-3=\dfrac{2}{1}(x)[/tex]

[tex]y-3=2x[/tex]

Adding 3 on both sides, we get

[tex]y=2x+3[/tex]

Therefore, the correct option is C.
