Question 1 The solution to 5 - 3x > 35 is either r > -10 or -10 > 2. Which solution is correct? Explain how you know. Edit View Insert Format Format Tools Table 12pt Paragraph BI U AY 2 T?​

Answers

Answer:

x < -10

Step-by-step explanation:

Given the inequality 5 - 3x > 35

Subtract 5 from both sides

5 - 3x - 5> 35 -5

-3x > 30

Divide both sides by -3

-3x/-3 < 30/-3

x < -10 (note the change is sign)

hence the correct solution is x < -10

after one side of a square was enlarged by 3 inches and the other side was enlarged by 3 inches, the area of the shape was doubled. what was the side of the square.

Answers

Answer:

The side of original square was 7.24 inches

Step-by-step explanation:

(x+3)(x+3) =2(x)(x)

x² + 6x + 9 = 2x²

reduce:

x² - 6x - 9 = 0

(x + 1.24)(x - 7.24) = 0

x = 7.24

What is the median of the following numbers?
3.31,37,56, 61,57,62

Answers

Answer:

The answer might be 56 because the median is the middle of it

we can start by putting them in order from least to greatest, which is 3.31,31,37,56,57,61,62. sorry if it doesn’t make sense, but basically just need to count from either side until you get to the middle and it’s even on each side, like 3.31,37-56,57-61,62 then find the middle in 56 and 57, which is 56.5

Answer:

= 1.156 × 10^9

(scientific notation)

= 1.156e9

(scientific e notation)

= 1.156 × 10^9

(engineering notation)

(billion; prefix giga- (G))

= 1156000000

Step-by-step explanation:

Simply subtract A from B = 1,156,000,000 and convert the answer to scientific notation.

Answer:

D. 1.156 times 10^9

First we subtract the difference,

1,300,000,000 - 144,000,000 = 1156000000

Next, we find the number 1156000000 written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 115,600,000

New Number: 1.15600000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 1 5 6 0 0 0 0 0

Decimal Count:   1 2 3 4 5 6 7 8

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 1.156 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

1.156 x 108

Step 4

Check your work:

108 = 100,000,000 x 1.156 = 115,600,000

Thus, 115,600,000 written in scientific notation is 1.156 times 10^9 estimated.

The diameter of a wheel on a car is 16 inches. What is the circumference of the wheel? Use 3.14 for pi.

Answers

Answer:

The circumference is 50.24in.

Step-by-step explanation:

All you have to do is multiply the diameter by 3.14. Easy and so simple

The circumference of the given wheel is 50.24 inches.

What is the Circumference of a circle?

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

We have been given data as follows:

The diameter of the circle (d) = 16 cm

Circumference of the circle = πd

Substitute the values in the above formula and we get

Circumference of the circle = 3.14 × (16)

Apply the multiplication operation, and we get

Circumference of the circle = 50.24

Thus, the circumference of the given wheel is 50.24 inches.

Answers

Answer: x = -3; y = -8

Step-by-step explanation:

Multiply second equation by -1 and add to first equation.  The y term zeros out, leaving you with -3x = 9, so x = -3.

Then go back and sub -3 in for x in either equation, and solve for y.  If you use the first equation, you get 4(-3) -3y = 12

-12 -3y = 12

-3y = 24

y = -8

Answer:

  B  They are similar, but not congruent.

Step-by-step explanation:

Reflection, rotation, and translation are "rigid" transformations. They result in congruent figures.

Dilation is not a rigid transformation. For any dilation scale factor other than 1, the figures will be different sizes, so will not be congruent. They will be similar. (Angles will be congruent, and lines/sides will be parallel.)

The combination of dilation (by 0.5) and reflection results in similar, but not congruent, figures.

Answers

Answer: 0.151 percent

Step-by-step explanation:

The probability of any particular outcome is

   (number of possible successful outcomes) / (number of total possibilities)

-- On the first draw, there are 52 possible total outcomes, and

only 4 that are successful ... drawing a 3 .

The probability of drawing a 3 from a full deck is  ( 4 / 52 ).

-- On the second draw, there are 51 possible total outcomes (the first

card you drew stayed out), and only one is successful ... drawing the

queen of hearts.

The probability of this particular outcome is   ( 1 / 51 ).

-- The probability of both of them is  

                                ( 4 / 52 ) x ( 1 / 51 ) =

                                      ( 4 / 2,652 )  =  about 0.151 percent.
