Do you guys know the answer?

Answer:

150

Step-by-step explanation:

This is a word problem which should be tackled accordingly.

The sum of 48 and itself

= 48+48

= 96

It's half and half of its half

= 48/2 and (48/2)/2

= 24+ 24/2

= 24+12

= 36

Is added to 18

= 96+36+18

= 150

From the description above the entire sum is 150.

Answer:

-9xy² - 6x²y + 5x

Step-by-step explanation:

The additive inverse of a polynomial is simply defined as the same polynomial but the difference is that the signs attached to each of the terms will change. This means that positive sign will change to negative while negative sign will change to positive.

Now, we are given the polynomial;

9xy² + 6x²y - 5x

Thus, from earlier description, additive inverse of this polynomial is;

-9xy² - 6x²y + 5x

Step-by-step explanation:

Answer:

a. s = [tex]\frac{d}{t}[/tex]

b. 9600 ft

Step-by-step explanation:

In the given question, the motion of the bee involves speed (s), distance (d) and its time of flight (t).

a. The equation required to determine the distance of the flowerbed from the hive/ hive to flowerbed is;

speed = [tex]\frac{distance}{time}[/tex]

i.e s = [tex]\frac{d}{t}[/tex]

b. Given that: the bee flies back at 8 feet per second, and in 20 minutes (1200 seconds);

s = [tex]\frac{d}{t}[/tex]

⇒ d = s x t

       = 8 ft/s x 1200 s

       = 9600 ft

The flowerbed is 9600 feet from the hive.

Answer:

The answer is B.

Step-by-step explanation:

Answer:

1) 8,388,608 grains of wheat.

2) 16,777,215 grains of wheat.

3) 239,674.5 pounds.

Step-by-step explanation:

Question 1)

We know that on the first square, there is 1 grain of wheat.

On the second, 2 grains of wheat.

On the third, 4 grains of wheat.

And on the fourth, 8 grains of wheat.

Therefore, we have a geometrically increasing sequence. It looks like:

1, 2, 4, 8...

Therefore, to find the number of grains on the 24th square, we can write an explicit formula.

The standard form for the explicit formula for a geometric sequence is:

[tex]x_n=a(r)^{n-1}[/tex]

Where a is the initial amount, r is the common ratio, and n is the nth term (starting from 1).

We know that the initial term a is 1 because there’s one grain of wheat on the first square.

And the common ratio will be 2 because each square has double the amount of the previous square.

So, substitute 1 for a and 2 for r. This yields:

[tex]x_n=1(2)^{n-1}\\[/tex]

We can simplify this:

[tex]x_n=2^{n-1}[/tex]

So, to find the amount of wheat on the 24th square, we simply need to substitute 24 for n and evaluate. So:

[tex]x_{24}=2^{24-1}=2^{23}[/tex]

Evaluate. Use a calculator:

[tex]x_{24}=8,388,608[/tex]

Therefore, on the 24th square, there are 8,388,608 grains of wheat.

Question 2.1)

We want to find the total number of grains of wheat on the board at this time.

In other words, we want to find the sum of our geometric sequence when n is 24.

The formula for the sum of a geometric series is:

[tex]S_n=\frac{a(r^n-1)}{r-1}[/tex]

Where rⁿ is the value of the number of terms n, r is the common ratio, and a is the initial term.

We want to find the sum after 24 times. So, n is 24.

So, substitute 24 for n, 2 for r, and 1 for a. This yields:

[tex]S_{24}=\frac{(1)(2^{24}-1)}{2-1}[/tex]

Evaluate. Use a calculator:

[tex]S_{24}=16, 777, 215[/tex]

Therefore, the total sum of the number of grains of wheat at the board at the 24th square is 16,777,215.

Question 2.2)

And to find the weight, we will just have to multiply our total amount by 1/7000. So:

[tex]W=16777215(\frac{1}{70})[/tex]

Use a calculator:

[tex]W=239,674.5\text{ lbs}[/tex]

So, the total weight is 239,674.5 pounds.

Answer:

B. Insurance

Step-by-step explanation:

Analysing the Question:

We are given the following equations:

x - y = 4

x + y = 9

writing these equations in slope-intercept form

y = x - 4

y = -x + 9

the general form of the slope-intercept equation is :   y = mx + b (where m is the slope and b is the y-intercept)

Hence, we can say that the for Equation 1:

Slope  = 1

y-intercept = -4

For equation 2:

Slope = -1

y-intercept = 9

Finding if the lines are Perpendicular, parallel or neither

If the slope of the lines is equal, the lines are parallel

If the slope of the lines is the additive inverse (negative) of each other, the lines are perpendicular

Since the slopes of the 2 lines are the additive inverse (negative) of each other, the lines are perpendicular     [slope 1 = 1    , slope 2 = -1]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Principal = $20000

Interest rate = 5.5% = 0.055 compounded daily

Time = 16years =(360 * 16) = 5760

n = number of times interest is applied per period

Amount of money in account after 16 years :

A = p(1 + r/n)^nt

A = total amount

A = 20000(1 + 0.055/360)^(360*16)

A = 20000(1 + 0.0001527)^5760

A = 20000(1.0001527)^5760

A = 48193.1611

Interest on principal :

$48193.1611 - $20000

= $28193.1611

Answer:

A; (X=5)

Step-by-step explanation:

Move the constants and variable terms to one side:

3x-5= -2x+10

-5+10= -2x+ 3x

Combine like terms:

5=x or x=5

Answer:

The answer is C

Step-by-step explanation:

If you take the equation and simplify it.

3x-5=-2x+10

You would minus 3x from both sides, leaving the equation like

-5=-5x+10

Then you would minus 10 from both sides, leaving the equation like

-15=-5x

If you wanted to go further you could divide both sides by -1 and get rid of the negatives. Leaving the equation like

15=5x

Then to put it into the simpleist   form you would divide both sides by 5, leaving the equation like

3=x

Answer:

Her new position is 37 feet below the cave entrance

Step-by-step explanation:

Let us solve the question

∵ The cave entrance is the zero position

∵ Anna is in 42 feet below the cave entrance

→ Below zero means negative

∴ Anna is in -42 feet

∵ She descends 10 feet

→ Descend means negative

∴ She is in -42 + -10 = -52 feet

∵ She ascends 15 feet

→ Ascend means positive

∴ She is in -52 + 15 = -37 feet

→ -37 means she is in below the cave entrance by 37 feet

∴ Her new position is 37 feet below the cave entrance

Answer:

A) True

Step-by-step explanation:

[tex]-4,-1[/tex]

If we subtract the two numbers we get

[tex]-4-(-1)=-4+1=-3[/tex]

It can be seen that subtracting the two numbers changes the sign of one number by which we can algebraically subtract the numbers. Since, the addition of 1 shifts the number towards zero in the number line, the minus sign still remains.

So A)-4 -1 is true.
