Answer:

x = 0, 1.333333...

Step-by-step explanation:

1) Convert both sides to the same base.

[tex]16^{1.5x^{2} } =16^{2x}[/tex]

2) Cancel the base of 16  on both sides.

[tex]1.5x^{2} =2x[/tex]

3) Move all terms to one side.

[tex]1.5x^{2} -2x=0[/tex]

4) Factor out the common term x.

[tex]x(1.5x-2)=0[/tex]

5) Solve for x.

1 - Ask: When will x(1.5x-2) equal zero?

When x = 0 or 1.5x - 2 = 0
2 - Solve each of the 2 equations above.

x = 0, 1.333333...

Answer:

[tex]\frac{7\times15}{100}[/tex]

Step-by-step explanation:

Given the following question:

7% of 15

To find the answer we need to use the formula to calculate percentages in which we multiply the percentage by the whole number and then divide that answer by 100, of course rounding to the nearest cent if needed.

[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{7\times15}{100}[/tex]
[tex]7\times15=105[/tex]
[tex]105\div=1.05[/tex]
[tex]=1.05[/tex]

7% of 15 is "1.05" which means Regina receives a $1.05 raise.

Answer:

12.5%

Step-by-step explanation:

Divide 1 by . Therefore, the fraction 18 is equivalent to 12.5% .

Answer:

8 quarters and 4 dimes

Step-by-step explanation:

4 quarters = 1 dollars

4 quarters = 1 dollars

4 dimes = 40 cents

2.40$

============================================

Work Shown:

d = number of dimes

q = number of quarters

1 dime = 10 cents

d dimes = 10d cents

1 quarter = 25 cents

q quarters = 25q cents

d+q = 12 since we have 12 coins total

q = -d+12 after solving for q

10d+25q = total value in cents

10d+25q = 240

10d+25(-d+12) = 240 ... plug in q = -d+12

10d-25d+300 = 240

-15d+300 = 240

-15d = 240-300

-15d = -60

d = -60/(-15)

d = 4

q = -d+12

q = -4+12

q = 8

Since d = 4 and q = 8, this means we have 4 dimes and 8 quarters

-----------------------------

Check:

4 dimes = 4*10 = 40 cents

8 quarters = 8*25 = 200 cents

(4 dimes) + (8 quarters) = (40 cents) + (200 cents) = 240 cents

240 cents = 240/100 = $2.40

We have 4+8 = 12 coins total

Answer:

10 centimeters = 0.1 meters

Step-by-step explanation:

Question  

How many meters are in 10 centimeters?

There are 100 centimeters in 1 meter.

Therefore, 1 centimeter = 1 ÷ 100 meters

                                       = 0.01 meters

So if 1 centimeter = 0.01 meters

Then 10 centimeters = 0.01 × 10 = 0.1 meters

Answer: YES, YOU CAN

Step-by-step explanation:

Answer:

adults pay $10

children pay $6

Step-by-step explanation:

x = adult

y = child

2x + y = 26

x + 3y = 28

you want to cancel out x or y

multiply -2 with (x + 3y = 28) which is -2x -6y = -56

2x + y = 26

-2x -6y = -56

-5y = -30

y = 6

put y back into an equation

2x + y = 26 is

2x + 6 = 26

x = 10

check the answer

Two adults and one child go to a movie and pay $26

20 + 6 = 26 : checks

One adult and 3 children pay $28

10 + 18 = 28 : checks

Answer:

  $8727

Step-by-step explanation:

The difference in investment values can be found by computing the value of each investment, then finding the difference. Here, we're concerned with investments compounded quarterly and compounded continuously.

Melanie's investment value is computed using the formula ...

  FV = P(1 +r/n)^(nt) . . . . where P is the principal, r is the annual rate, t is the number of years

  FV = $63,000(1 +0.07125/4)^(4×15) = $63,000(1.0178125^60)

  FV = $181,721.94

__

Lillian's investment value is computed using the formula ...

  FV = Pe^(rt)

  FV = $63,000·e^(0.07375×15)

  FV = $190,449.05

__

The amount more that Lillian has is ...

  $190,449.05 -181,721.94 = $8,727.11

Lillian has about $8727 more than Melanie.

The required mass of Aunt jane is given as 4.5 kilograms.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given that, Aunt Jane weighs 45 newtons.
So,
F = 45

Since F = Mg,
Mg = 45
M(10) = 45
N = 4.5 kilograms,
