Answer:

x=8

Step-by-step explanation:

We have been given with the function:  

Here, we have same base of logarithmic function on both sides of the equation.

So, we will equate the values on right hand side and left hand side of the equation we will get  

After simplification we will get  

After further simplification we will get  

Hence,  

Therefore the correct answer is 8.

Answer:

15

Step-by-step explanation:

Answer:

She made a final grade of 80% or you could say she got 20% of the questions wrong.

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.

Answer: C

Step-by-step explanation:

The first 2 letters match but the third one doesn’t and S= match so it is SSA

Answer:

149? I could be wrong I haven't done this type of math in a while.

Step-by-step explanation:

From B to D, that angle would be 180. so 180 - 31 = 149

Answer:

Step-by-step explanation:

The diameter of a circle is twice the radius, so the statement is false.

Answer:

96/18

Step-by-step explanation:

To simplify you need to turn it into an improper fraction. This means that the numerator (the number on top) is greater than the denominator (the number on the bottom). The improper fraction form of 5 6/18 is 96/18. I believe this is the answer to your question.

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.

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.

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.

Answer:

B. 40

Step-by-step explanation:

We know that the large angle is 90 degrees as it is a right angle. Thus, [tex]10+2x=90[/tex] (I don't know how to include degree symbols). We solve: [tex]2x=80[/tex], so then [tex]x=40[/tex]. Thus, x is forty degrees and the answer is B.

Answer:

40

Step-by-step explanation:

There is a bisector splitting a 90-degree angle into 2 parts, we are given that one of them is 10. This can only mean the other side is 80 degrees in total.

and 80/2 is 40

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

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.

Answer:

A. 3.6 kilometers

Step-by-step explanation:

1000 meters = 1 km

3600 meters = x km

Set as a ratio:

1000 : 1 = 3600 : x

Then divide:

[tex]\frac{3600}{1000} = \frac{x}{1} = x[/tex]

so 3600/1000 = 3.6 = x

3.6 km
