Step-by-step explanation:

Ok so first of all, Why does rob need a mp3 player? we are in the new age, right?

Secondly, I will answer your question :P

Ok so we have some info here .... we know that Rob earns $15 and saves $6

We can assume that Rob earning's equation would be y = 15x-6x

We are also given that he earned $75 (My gosh Rob nice work man!)

we would plug in 75 for y >>>for now forget the fact that Rob saves<<<

Divide 75 by 15 which = 5

Now multiply 6 by 5 which = 30 (AnSWERR!)

We now also know that out of what Rob earned he used or donated to charity $75-30 = $ 45

We can double check our work here real quick

[tex]45=15x-6x\\45=(15*5)-(6*5)\\45= 75 - 30 \\45 = 45  true[/tex]

Answer:

The number of letters in the one street be 220 .

Step-by-step explanation:

As given

A postman has to deliver 450 letters .

The number of letters delivered in one street is twice the number delivered in other .

Let us assume that the number of letters delivered in second street be x.

Let us assume that the number of letters delivered in first street = 2x

As given

If he is left with 120 letters .

Thus

The number of letter delivered in one and other street  = 450 - 120

                                                                                            = 330

Than the equation becomes

x + 2x = 330

3x = 330

[tex]x = \frac{330}{3}[/tex]

x = 110

The number of letters in the one street = 2 × 110

                                                                  = 220

Therefore the number of letters delivered in first street be 220.

The postman delivered 110 letters to the first street and 220 letters to the second street

This is a problem of simple algebra where you have to solve for unknowns. We know the postman has 450 letters in total, and 120 are left after delivering to two streets. So, the total number of letters he delivered is 450 - 120 = 330 letters.

Let’s say the number of letters delivered in one street is x. Therefore, the number of letters delivered in the other street would be 2x because it's twice the number delivered in the first street.

Since the postman delivered all 330 letters in two streets, the equation becomes x + 2x = 330. Simplifying this we get 3x = 330. Then, solve for x by dividing both sides by 3, so x = 330 / 3 = 110.

Therefore, the number of letters delivered in the first street is x = 110, and in the second street it's 2x = 2*110 = 220.

Answer:

The second choice.

Step-by-step explanation:

f(x) = -(x + 1)^2 + 4

This is a parabola which opens downwards ( because the coefficient of x is negative).

This is the vertex form of a parabola:  f(x) = a(x - b)^2 + c where the vertex is at (b, c). So in this case:-

The vertex is at (-1, 4).

The domain is  All Real Numbers and the Range is (-∞, 4]  (or y ≤ 4)

Answer:

In 30 minutes:

The minute hand moves a distance of 25.13 inches

In 20 minutes:

The minute hand moves a distance of 16.76 inches

Step-by-step explanation:

When 60 minutes are completed, the minute hand of the relog makes a complete revolution. The distance s that the minute hand travels when making a complete revolution is:

[tex]s = 2\pi r[/tex] Where r is the radius of the circumference, and in this case, the radius of the minute hand.

So:

[tex]s = 16 \pi[/tex]

s = 50.27 inches.

In 30 minutes (which is half of 60) the minute hand covers only half a revolution. Then the distance traveled in 30 minutes is [tex]\frac{1}{2}(s) = 25.13[/tex] inches

In 20 minutes (which is one third of 60) the minute hand only travels a third of a complete revolution. Then the distance traveled in 20 minutes is [tex]\frac{1}{3}(s) = 16.76[/tex] inches

We calculate the distance traveled by the minute hand of a clock by using the arc length formula from geometry. Using the length of the hand as the radius and the angle covered as a fraction of 360 degrees (converted into radians), we can determine the distances for 30 and 20 minutes as 8π inches and 16/3 π inches respectively.

The subject of our question involves the calculation of arc lengths (distances) moved by a clock hand, an aspect of geometry. We'll be treating the minute hand of a clock as a line segment that sweeps out a circular path. The arc length formula will be utilized here, which is given by the equation L = rθ, where L is the arc length, r is the length of the minute hand (as the radius), and θ is the angle covered by the minute hand.

In a span of a whole hour or 60 minutes, the minute hand completes a full 360° circle. So, for 30 minutes, it covers half the circle which equates to 180°. This degree measure needs to be converted to radians because our formula uses radian measure. 180° equals π radians.

With r = 8 inches and θ = π, we substitute these values into our formula to get L = 8π inches for 30 minutes.

The same concept applies for 20 minutes. In this case, the hand covers a third of the circle which is (360/3)=120°, this is (2/3)π in radian. Substituting r = 8 inches and θ = (2/3)π into our formula, we get L = 16/3 π inches for 20 minutes.

Introducing a change to the subgroup

Step-by-step explanation:

Given there are four statements.  We have to find the one which represents one of the differences between an experiment and an observational study.

The answer is option 2. Introducing a change to the subgroup

Experimental and observational studies are both types of studies between which a number of differences can be identified. When conducting research studies,  various types of research in order to arrive are adopted according to the need.  

An experimental study is a study where the researcher has control over most of the variables.

On the other hand, an observation study is a study where the researcher cannot control any variable but merely observes the subject without controlling any variables.

Answer:

B

Step-by-step explanation:

When x = 2, the expression evaluates to -442/3.

To evaluate the expression when x = 2, we substitute 2 for x in the expression:

x + 4/(3x) - 150

Now, we plug in the value of x:

2 + 4/(3 * 2) - 150

First, we simplify the denominator:

2 + 4/6 - 150

Now, simplify the fraction:

2 + 2/3 - 150

Next, we need to find a common denominator, which in this case is 3:

(3 * 2)/3 + 2/3 - 150

Now, add the fractions with the common denominator:

(6/3) + (2/3) - 150

Combine the fractions:

(6 + 2)/3 - 150

Now, perform the addition in the numerator:

8/3 - 150

To subtract a fraction from a whole number, we need a common denominator. In this case, it's 3:

(8/3) - (150 * 3/3)

Now, subtract:

8/3 - 450/3

Subtract the numerators:

(8 - 450)/3

Now, perform the subtraction in the numerator:

-442/3

So, when x = 2, the value of the expression x + 4/(3x) - 150 is -442/3.

Answer:

Jess's bill amount without tip: B

Jess's tip amount: 0.21B.

Jess's total bill amount: [tex]B+0.21B[/tex]

Step-by-step explanation:

We have been given that Jess has dinner at a restaurant. The dinner bill is B dollars. So the Jess's bill amount without tip will be B dollars.

We are told that she pays a 21% tip. Let us find 21% tip of dinner bill (B).  

[tex]\text{Jess's tip amount}=\frac{21}{100}*B[/tex]

[tex]\text{Jess's tip amoun}=0.21B[/tex]

Therefore, Jess's tip amount will be [tex]0.21B[/tex].  

Let us find total amount of Jess's bill by adding bill amount (0.21B) to the Jess's bill amount without tip (B).

[tex]\text{Total amount of Jess's bill}=B+0.21B[/tex]

Therefore, the total amount of Jess's bill will be [tex]B+0.21B[/tex].

Jess's bill without tip is B, her tip amount is 0.21B, and her total bill including a 21% tip is 1.21B.

When Jess has dinner at a restaurant with a dinner bill of B dollars and decides to pay a 21% tip, you can calculate her expenditures in the following manner:

Therefore, the expressions that match their correct meanings for Jess are as follows: Jess's bill amount without tip: B, Jess's tip amount: 0.21B, Jess's total amount: 1.21B.

[tex]Answer:\ \boxed{C.\ (2+\sqrt3)}[/tex]

The correct answer to the question is therefore C. 2 + square root of 3.

If (2 - square root of 3) is a root of a polynomial with integer coefficients, the polynomial must have another root that is the conjugate of (2 - square root of 3), which is (2 + square root of 3). This is due to the Conjugate Root Theorem, which is a result of the fact that the coefficients of the polynomial are real numbers. When you have a non-real root in such a polynomial, its conjugate will also be a root.

The correct answer to the question is therefore C. 2 + square root of 3.

Adam's cleats cost $65 and the sales tax is 5.5%. The sales tax amount is calculated by multiplying the price by the tax rate. The total cost is the sum of the initial price and the sales tax which is approximately $68.58.

Adam is buying a new pair of baseball cleats for $65 and the sales tax is 5.5%. To find the total cost, we must find out the cost of the sales tax first. The sales tax can be calculated by multiplying the cost of the cleats by the sales tax percentage (in decimal form).

So, $65 * 0.055 = $3.575 is the tax amount. This means the sales tax on the cleats is $3.575.

The total cost Adam needs to pay is the sum of the cost of the cleats and the sales tax. Hence, $65 + $3.575 = $68.575. Therefore, the total cost that Adam will pay is approximately $68.58, because we usually round the money amount to the nearest cent.
