Car A is traveling east at a steady speed of 50 miles per hour. After 2 hours, it
is 140 miles east of Johnstown.

Car B is traveling east on the same road. Its distance east of Johnstown is
represented by the graph.

Where were the two cars in relation to each other when they began traveling?

A. Car A was 20 miles east of car B
B. Car B was 40 miles east of car A
C. Car A was 40 miles east of car B
D. Car B was 20 miles east of car A

Answer:

Basically you just add the like terms together. Like terms are terms that have the same power, like 1, or 2 to the second power. x has a power of zero.

Answer:

40J

Step-by-step explanation:

YOU say 1/2 x 5 x4² ( 4 is velocity. 5 is mass )

it becomes 1/2 x5 x16

then it becomes 1/2 x 80

half of 80 is 40

the answer is then 40 JUOLES

Step-by-step explanation:

did this test and got a 100

Answer:

The correct answer for this question is that the unit rate is 5:1. We can work this out by simplifying down the 2 commercials to every 10 songs ration, so that 10:2 becomes 5:1. We can work this out by halving the original ratio to simplify it. Hope This helps.

Step-by-step explanation:

Answer:

54:78

Step-by-step explanation:

We multiply 9 and 13 to 6

9 × 6 = 54

13 × 6 = 78

54 + 78 = 132

Ratio representation gives the sharing proportion of a number, the numbers expressed in the ratio 9:13 of 132 are 54 and 78 respectively

Given the Parameters :

To obtain each Value, we use the relation ;

For the 9 portion of the ratio :

(9 / (9+ 13)) × 132

(9 / 22) × 132

= 54

For the 13 portion of the ratio :

(13 / (9+ 13)) × 132

(13 / 22) × 132

= 78

Therefore, the two numbers are 54 and 78

Answer:

45mph

Step-by-step explanation:

To find the average speed, we must add together all of the different speeds and divide by the quantity of them (assuming all of them are equal in time). In this case we have 2: 50 and 40.

[tex]50+40=90[/tex].

Then we divide by 2, since there were two segments of equal length

The question is wrong because as the given angle is 90, the hypotenuse(11cm) should be greater than 16cm

280 student tickets

520 adult tickets

Explanation:

I'm guessing this is the question you meant to ask:

Eight hundred tickets were sold for a movie production and the receipts for the performance wear $8600. The tickets for adults and students sold for $12.50 and $7.50, respectively. How many of each ticket were sold?

Answer:

The quadratic x2 − 5x + 6 factors as (x − 2)(x − 3). Hence the equation x2 − 5x + 6 = 0

has solutions x = 2 and x = 3.

Similarly we can factor the cubic x3 − 6x2 + 11x − 6 as (x − 1)(x − 2)(x − 3), which enables us to show that the solutions of x3 − 6x2 + 11x − 6 = 0 are x = 1, x = 2 or x = 3. In this module we will see how to arrive at this factorisation.

Polynomials in many respects behave like whole numbers or the integers. We can add, subtract and multiply two or more polynomials together to obtain another polynomial. Just as we can divide one whole number by another, producing a quotient and remainder, we can divide one polynomial by another and obtain a quotient and remainder, which are also polynomials.

A quadratic equation of the form ax2 + bx + c has either 0, 1 or 2 solutions, depending on whether the discriminant is negative, zero or positive. The number of solutions of the this equation assisted us in drawing the graph of the quadratic function y = ax2 + bx + c. Similarly, information about the roots of a polynomial equation enables us to give a rough sketch of the corresponding polynomial function.

As well as being intrinsically interesting objects, polynomials have important applications in the real world. One such application to error-correcting codes is discussed in the Appendix to this module.

Step-by-step explanation:

a diameter is always twice the radius.

the only pairs in this list, where one number is twice the other, is :

2.5 and 5

7.6 and 15.2

so,

2.5 is the radius of A

5 is the diameter of A

7.6 is the radius of B

15.2 is the diameter of B

15.7 is then the circumference of A (as the smaller of the remaining 2 numbers).

47.7 is the circumference of B.

this is also proven by the formula for the circumference of a circle : c = 2×pi×r
