Given:

In an asteroid field, 75% of the asteroids are carbonaceous asteroids.

There are 375,000 carbonaceous asteroids in the asteroid field.

To find:

The number of asteroids that are not carbonaceous.

Solution:

Let the total number of asteroids be x.

According to question,

[tex]75\%\text{ of }x = 375000[/tex]

[tex]\dfrac{75}{100}x=375000[/tex]

[tex]0.75x=375000[/tex]

Divide both sides by 0.75.

[tex]x=\dfrac{375000}{0.75}[/tex]

[tex]x=500000[/tex]

Asteroids not carbonaceous = Total asteroids - Carbonaceous asteroids

                                                [tex]=500000-375000[/tex]

                                                [tex]=125000[/tex]

Therefore, 125,000 asteroids are not carbonaceous.

Answer:

x=4

Step-by-step explanation:

Let's solve your equation step-by-step.

2x−3=x+1

Step 1: Subtract x from both sides.

2x−3−x=x+1−x

x−3=1

Step 2: Add 3 to both sides.

x−3+3=1+3

x=4

Answer:

x=4

2x - 1x = x

x-3= 1

3+1 =4

so x=4

Answer:

The exponential function x is neither. An exponential function is a sum of an even and an odd fuction. The even fuction is known as even x and odd function is known as  x. the x is even function and sinx is odd function.

But thats if its an x funtion so uf its just a plain function its known to be even!

Answer:

{-14, -2, 10}

Step-by-step explanation:

To find the range, you can use all the domain values and find the output.

f(-4) = 3(-4) - 2

f(-4) = -12 - 2

f(-4) = -14

f(0) = 3(0) - 2

f(0) = 0 - 2

f(0) = -2

f(4) = 3(4) - 2

f(4) = 12 - 2

f(4) = 10

Best of Luck!

Answer:

184in

Step-by-step explanation:

Since the scale for the statue is 3 inches to 100 feet, we can say 3:100 as a ratio.

To find approximately 305 feet you must divide 305 by 100.

100 can go into 300 evenly 3 times. Since the ratio is 3:100 you should multiply how many times the 100ft fit into the 300ft and the 3in (3 x 3) which is about 9in.

One way we can do this is to divide the hight of the Statue by the model height:

305ft 20in = 15.25ft 1in or 184in (12in per foot).

And so for every inch of the model, it represents 15.25 feet.

For 305 it would be

Answer:

40 degrees

Step-by-step explanation:

We need to find angle 3

Since angle 2 and angle 4 are vertical angles, they will be congruent

To solve for x we can make the following equation:

x+70=2x

x=70

In this problem angles 2 and 3 are supplementary (they add to 180)

Angle 2 is 140 degrees

We can now make the following equation to find angle 3 using measures addition postulate

let angle 3 be x

180-140=x

The 140 is angle 2

x=40

James would be spending the amount of  $75.80 which is the correct answer would be an option (D).

In mathematics, the multiplication operation Values on each side of the operator are multiplied.

We have been given that there were t-shirts for sale for $18.95 each at the amusement park, and James bought 4 of them.

To determine the amount of cost did he spend.

The amount of cost is equal to the multiplication of each t-shirts cost and

quantity.

The amount of cost = the cost of each t-shirt × quantity

The amount of cost = $18.95 × 4

Apply the multiplication operation to get

The amount of cost = $75.80

Therefore, he would be spending the amount of  $75.80.

-Have a nice meal!

Answer: 3.25 + 5.50s ≤ 30

Step-by-step explanation:

The following information can be gotten from the question.

Cost of chocolate milk = $3.25

Cost of stack pancake = $5.50

Maximum amount to be spent by Benjamin = $30

Number of stacks of pancakes to be bought = s

First, we need to calculate the stacks of pancakes that Benjamin can buy. This will be:

= $5.50 × s

= 5.50s

Therefore, the total money that Benjamin will spend will be:

= 3.25 + 5.50s

Since he wants to be able to be at most $30 before tax, the inequality can be written as:

= 3.25 + 5.50s ≤ 30

The Graph transformation of [tex]f(x) = 7^x[/tex] which stretched vertically by a factor of five is  [tex]g(x) = 5(7^x)[/tex] .

Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph .

According to the question

The graph of [tex]f(x) = 7^x[/tex]  stretched vertically by a factor of five .

i.e

we have to make change is graph equation so y axis changes 5 times .

Therefore ,

[tex]f(x) =( 7^x ) * 5[/tex]

The Graph transformation  of f(x) is

[tex]g(x) = 5(7^x)[/tex]

Hence, the Graph transformation of [tex]f(x) = 7^x[/tex] which stretched vertically by a factor of five is  [tex]g(x) = 5(7^x)[/tex]

Explanation:

The calculator never lies. Oh, and also, you can tell the answer to seven and eight by where the decimal points are located.

hi

16p +24 = 48

16p = 48-24

 16p = 24

    p = 24/16

    P =  8*3 /8*2

    p =    3/2

Answer:

3/2

Step-by-step explanation:

First move 24 to the other side. Therefore, you subtract 24 from 48 (48-24). You’re left with 16p= 48-24. That is 16p=24. Now we are trying to find p so we’re going to divide both sides by the coefficient of p which is 16. So, p= 24/16. Both 24 and 16 are multiples of 8 so you can simplify to p=3/2.
