On evaluating the fraction 3 3/4 the cost of 3 3/4 kg of sugar is $30.

What is fraction?

In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.

The cost of 1 kg of sugar is = $ 80

The amount of sugar is given in fractional form - 3 3/4 kg

The equation for cost of 3 3/4 kg sugar is -

Cost = 3 3/4 × 8

Solve the fractional part first -

Cost = 15/4 × 8

Simplify the equation -

Cost = 15/4 × 8

Cost = 120/4

Cost = 30

Therefore, the cost value is obtained as $ 30.

The component of u+v along the length of u and v  is (6.3, 0.66).

A vector is quantity which has both magnitude and direction. A magnitude is the length of the vector.

Here in the question u and v makes angle with the positive x axis.

||u||= 4 and θu =6  and  ||v|| = 1, θv = 4

To determine the component of u = |u||(cosu, sinu)

Component of u = 6(0.9, 0.1) = (5.4, 0.6)

Component of v = ||v||(cosv sinv)

Component of v  along the x axis = 1(0.9, 0.06 ) = (0.9, 0.06)

In the question value of u+v needs to be find.

Value of u + v = (5.4 + 0.9 , 0.6+ 0.06)

Value of the component form of u + v = (6.3, 0.66).

Hence, the component of u+v along the length of u and v is (6.3, 0.66).

The probability that it will snow on both days, given the chances of snow on Saturday and Sunday, is 24.5%.

The chance of it snowing on both days is calculated by multiplying the probability of it snowing on Saturday by the probability of it snowing on Sunday. If the probabilities are independent, we can assume that one event occurring doesn't affect the other event, therefore the probability of both events happening is just the product of the individual event probabilities.

So, the chance of it snowing on both days is:

P(Saturday and Sunday) = P(Saturday) x P(Sunday)

P(Saturday and Sunday) = 0.35 x 0.70

P(Saturday and Sunday) = 24.5 %

If the relation is represented by the equation y = 2x + 1, the domain would be all real numbers (-infinity, +infinity) and the range would be all real numbers greater than or equal to 1 (1, +infinity).

A relation is a function if for every input (x) there is exactly one output (y). To determine if a relation is a function, we can use the vertical line test, which states that if a vertical line can be drawn through the graph and intersects the relation more than once, then the relation is not a function.

If the relation is a function, we can find the domain and range by analyzing the relation. The domain is the set of all x-values and the range is the set of all y-values. In interval notation, the domain is written as (a, b) and the range is written as (c, d).

So, the domain and range answers depend on the relation which is given and it should be specified.

The probability for these are

Probability(a dime and then a quarter)=3/76

Probability(two pennies)=33/95

 Probability(a quarter and then a penny)=9/95

What is probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. To find the probability of a single event to occur, first, we should know the total number of possible outcomes.

Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes

Now,

Quarters=3, Dimes=5 and Pennies=12

Total=20

Probability(a dime and then a quarter)=5/20*3/19=15/380=3/76

Probability(two pennies)=12/20*11/19=132/380=33/95

The solution to the system of equations is 6x – 2y = -14 with x = -4 and y = -5

4x – 3y = -31

To find x or method, you must first make one of the words the same so that they may cancel out.

To determine the x terms, we will make the y terms the same in this example.

To do so, multiply the first equation by three, yielding:

18x – 6y = - 42

And multiply the second equation by two to get:

8x – 6y = - 62

Now that we have the y terms, you may cancel them out.

You now have the following two equations:

18x = -42

8x = -62

The next step is to combine them, since the preceding – and – form a +.

This implies that you are left with one equation

26x = -104

Now divide by 26 on each side to get:

x = -4

As you have x, you substitute it into one of the ORIGINAL equations.

6x – 2y = -14

Substitute x in:

6(-4) – 2y = -14

-24 – 2y = -14

Add 24 on each side to get:

-2y = 10

y = -5

The amount of juice for 30% orange juice is 22 liters,

and the amount of juice for 5% orange juice is 3 liters mixed together in order to get 25 Liters.

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

Given One canned juice drink is 30% orange juice, another is 5% orange juice,

Let x and y be the amount of 30% and 5% orange juice respectively,

according to condition

0.30x + 0.05y = 0.27(25) .........(1)

x + y = 25.........(2)

Multiply the second equation by -0.05,

0.30x + 0.05y = 0.27(25)

-0.05x - 0.05y = -0.05(25)

Add equation to eliminate y,

0.30x - 0.05x + 0.05y - 0.05y = 0.27(25) - 0.05(25)

Solve for y,

0.25x = 5.5

x = 5.5/.25

x = 22

substitute value of x in equation,

x + y = 25

The average speed is 0 m/s since the object does not move.

Since the object does not change its position, it does not move. Therefore, its average speed is 0 m/s.

The object in question does not move in a closed path, meaning that its position remains the same throughout the entire path. As a result, its average speed is 0 m/s. This is because average speed is the total distance traveled divided by the total time taken, and since the object does not move its distance traveled is 0 and its time taken is also 0. Therefore, when the object goes around the closed path, its average speed is 0 m/s.

Answer:

You have let out 48.5 feet of string

Step-by-step explanation:

Attached is a sketch of the problem.

We can use SOH CAH TOA to find our answer.

In this acronym, O is the opposite side, A is the adjacent side, and H is the hypotenuse. S is for the SIN function. C is for the COS function. T is for the TAN function.

We can calculate the length of the string by using the SIN function.

So we can say the sine of angle x is the opposite side divided by the hypotenuse.

[tex]sin(x)=\frac{O}{H}[/tex]

Lets solve for [tex]H[/tex].

Multiply each term by [tex]H[/tex].

[tex]H*sin(x)=\frac{O}{H} *H[/tex]

Simplify the right side by cancelling the common factor of [tex]H[/tex].

[tex]H*sin(x)=O[/tex]

Divide both sides of the equation by [tex]sin(x)[/tex].

[tex]\frac{H*sin(x)}{sin(x)} =\frac{O}{sin(x)}[/tex]

Simplify the right side by cancelling the common factor of [tex]sin(x)[/tex].

[tex]H=\frac{O}{sin(x)}[/tex]

Now lets evaluate the length of the string.

In this example we are given

[tex]x=68\\O=45[/tex]

[tex]H=\frac{45}{sin(68)}[/tex]

[tex]H=48.5341[/tex]

The number of feet that canyon wall away from the person will be 3,300 feet.

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

Sound travels about 750 miles per hour. If you stand in a canyon and sound a horn, you will hear an echo.

Convert the speed in feet per second. Then we have

Speed = 750 x 5280 / 3600

Speed = 1,100 feet per second

Let 'n' be the number of seconds. Then the distance is given as,

1,100 = (d / 2) / n

d = 2,200 n

If n = 1.5, then we have

d = 2,200 x 1.5

d = 3,300 feet
