Answer:

  5.4×10^-1

Step-by-step explanation:

An adjustment in the exponent is needed to get to scientific notation at the end.

  (9×10^5)(6×10^-7) = (0.9×10^6)(6×10^-7) = (0.9×6)×10^(6-7)

  = 5.4×10^-1

_____

The applicable rule of exponents is ...

  (a^b)(a^c) = a^(b+c)

_____

Of course, it can be useful to understand how moving the decimal point changes the exponent:

  9 = 0.9×10 = 0.9×10^1

Answer:

0.5x+0.3y >= 3

sorry I don't know how to make the less than or equal to sign

Step-by-step explanation:

he can buy X amount of gumballs if he buys Y amount of jawbreakers and that will be less than or equal to $3

to graph, you must plug the number 0 into the X spot and solve.

0.5(0) +0.3y >= 3

next plug in for Y

0.5x+0.3(0) >= 3

plot these two points on the graph and draw a line through them

The inequality for the given situation is 0.50x+0.30y≤3. The graph for the obtained inequality is given below.

Given that, Gumballs cost $0.50 each, and jawbreakers cost $0.30 each. Bob has $3.00 to spend on candy.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Let the number of Gumballs be x and the number of jawbreakers be y.

The inequality for the given situation is

0.50x+0.30y≤3

Graph the inequality by finding the boundary line, then shading the appropriate area.

y≤−1.6x+10

The graph for the obtained inequality is given below

Therefore, the inequality for the given situation is 0.50x+0.30y≤3. The graph for the obtained inequality is given below.

Answer:

x³ + 4x² - 20x - 40

Step-by-step explanation:

Break it up into parts

(x+2)(x-4)(x+6)

( (x+2)(X-4) )(x+6)

Multiply (x+2)(x-4)

Breaking up the brackets, you get:

x(x-4)+2(x-4)

=x² - 4x + 2x -8

=x² - 2x - 8

Now multiply this by (x+6)

(x+6)(x² - 2x - 8)

= x³ - 2x² -8x + 6x²- 12x - 40

= x³ + 4x² - 20x - 40

Answer:

x = 8, y = 6

Step-by-step explanation:

2x + 5y = 46______(1)

3x - 2y = 12_______(2)

(1) x 3 --> 6x + 15y = 138

(2) x 2 --> 6x -4y = 24

(1) - (2) --> 19y = 114

                    y = 6  sub into (2)

3x - (2 x 6) = 12

             3x = 24

               x = 8

Answer:

(4, 4 )

Step-by-step explanation:

Given the 2 equations

- 6x + 6y = 0 → (1)

9x - 8y = 4 → (2)

Multiplying (1) by 3 and (2) by 2 and adding will eliminate the x- term, that is

- 18x + 18y = 0 → (3)

18x - 16y = 8 → (4)

Add (3) and (4) term by term to eliminate x, then

2y = 8 ( divide both sides by 2 )

y = 4

substitute y = 4 into either of the 2 equations and solve for x

Substituting into (2)

9x - 8(4) = 4

9x - 32 = 4 ( add 32 to both sides )

9x = 36 ( divide both sides by 9 )

x = 4

Solution is (4, 4 )

7:14 = 10:20

Step-by-step explanation:

Answer:

x=7

Step-by-step explanation:

this is a ratio problem which the ratios could be seen as fractions

x/14 = 10/20

then you and use the cross multiply method to solve this equation

20x = 140

x = 7

also another way is to find the previous 10/20 which gives you 1/2 and 1/2 of 14 is 7

Option C is the correct answer

Answer:

Part A:

0.1111111111111 = 1/9

Part B:

3

Step-by-step explanation:

Part A:

When I put 0.111111111 into my calculator I get a conversion of 1/9.

Part B:

The fraction 1/9 means that for every 9 kids he surveyed, 1 of them replied "yes."

So covert 1/9 into x/27

27/9 = 3 which means 9 goes into 27, 3 times.

Multiply 1 by 3.

1 x 3 = 3

Put into fraction form

3/27

This means 3 students out of 27 answered "yes."

Given:

Jimmy reads a book with 21,356 words.

Bob reads a book with one-and-a-half times as many words.

To find:

The expression that represents the number of words Bob reads.

Solution:

We have,

Number of words Jimmy reads = 21,356

Bob reads a book with one-and-a-half times as many words. So,

Number of words Bob reads =  Number of words Jimmy reads × one-and-one-half

                                               [tex]=21,356\times 1\dfrac{1}{2}[/tex]

Answer:

Step-by-step explanation:

Sum of angle in a triangle=180°

Given angle are= 60°,60°,y°

So 60+60+Y=180

Y=180-120

Y=60°(option d) is answer

Answer:

Since, a triangle’s interior angles makeup 180°

80°+60°+y=180

140°+y=180

y=180°-140°

y=40°

But, it can be option A because it’s an equilateral triangle and the angles don’t math, an equilateral triangle has equal angles

So, it’s one of them
