Find a and b if

2^a×3^b=12

**Answer:**

12=12

**Step-by-step explanation:**

2a = b

a -3b =12

To solve, set one of the equations equal to zero. The first equation is actually already set to 0.

b = 2a

Now you can plug this equation into the other one, by substituting the b in the equation with this.

a -3b = 12

a – 3(2a) = 12

Now all you have to do is distribute the 3 (multiply the number outside the parenthesis, 3 in this case, by everything inside).

a – 6a = 12

Combine like terms. Since we have 1 positive a and 6 negative ones, we subtract the two numbers without the signs

6-1 = 5

And take the sign of the larger number. Since 6 is large and 6 is negative, we are left with

-5a = 12

Now solve for a, which in this case means dividing both sides by -5

a = -12/5

Simplify

a = -2.4

Now that you have a, it’s easy to find b

b = 2a

b = 2(-2.4)

b= -4.8

Now you check your work by plugging your new a and b into either equation to see if it’s true.

-4.8 = 2(-2.4)

-4.8 = -4.8

And just for laughs let’s try the other equation

a -3b =12

-2.4 – 3(-4.8) = 12

Distribute the 3 again. Remember that when two negative numbers are multiplied they become positive.

-2.4 +14.4 = 12

12 = 12

**Step-by-step explanation:**

Apparently, you're being asked to identify the sequence of steps you would use to compute the volume of the pyramid.

It seems to be a good idea to start with the formula for the volume.

Then, recognize that you need to compute B, so make that computation. The area of the base (B) is the product of the base dimensions (14)(12).

Once you have the value of B, then you can put that, along with the value of h, into the original volume formula.

Evaluating it gives the volume in cubic units.

_____

*Additional comment*

If you're familiar with the pyramid volume formula, you know that you must compute B before you can make use of the formula. That makes the sequence be B=14(12); B=168; V=1/3Bh; V=1/3(168)(7).

However, if you're starting from scratch, it is probably good to begin with the volume formula. That is what tells you that you need to find B in the first place. This is the sequence we show below.

The next model of a sports car will cost 5.6% less than the current model. The current model costs $52,000. How much will the price decrease in dollars? What

will be the price of the next model?

**Answer:**

49,088

**Step-by-step explanation: **

**First you need to find 5.6% of 52,000. Simply multiply 52,000 by 0.056 (change the percent to a decimal) then you get 2,912.**

**Second, you need to subtract 2,912 from 52,000 which is 49,088**

Boy Scout camp and walk 6 km due east he then turns and walks 9 km due south what is his distance away from the camp at this point

You are going to use the Pythagorean there on as the two directions make a 90 degree angle.

A^2+B^2=C^2

6^2+9^2=C^2

36+81=C^2

117=C^2

Square root both sides

C=10.82km

A^2+B^2=C^2

6^2+9^2=C^2

36+81=C^2

117=C^2

Square root both sides

Simultaneous Equations - 5p-2q=9 3p+2q=7

**Apnswer:**

p = 1

q = -2

**Step-by-step explanation:**

5p - 2q = 9 eqn 1

3p + 2q = 7 eqn 2

subtract equation 2 from 1

2p = 2

p = 1

Substitute for p in equation 1

5(1) - 2q = 9

5 - 2q = 9

-2q = 4

q = -2

There were 680 gallons of water ALREADY in a 1600-gallon pool. Water is being pumped into the pool at the rate of 320 gallons per hour. Let x represents the number of hours. Find how many hours it will take to fill the pool.

**Answer:**

2 7/8 hours

**Step-by-step explanation:**

**Answer:**

2hrs 12 mins

**Step-by-step explanation:**

5hrs = 5x = 1600 question asks us to find 680

2 1/2x + 680-640 =-x + 2.8hrs

2x + 40 = x + 2.8hrs

2x + 40 = 680

Then use the 2.8 to convert into hrs : minutes ie) 0.8 x 60

0.8 * 60 = 48 minutes

Then go back to x + 2.8hrs = x + 2hrs 48mins

2x + 48 = 60

2x + 48 = 60

2x+ 60 - 48

x = 2:12 hours

**Answer:**

**Step-by-step explanation:**

At a movie night,1/4 of the persons were boys,5/8 were girls and the rest were adults.If there were 56 more girls than adults how many persons were in total?

**Given:**

Number of boys = [tex]\dfrac{1}{4}[/tex] of the total persons.

Number of girls = [tex]\dfrac{5}{8}[/tex] of the total persons.

Remaining persons are adults.

There were 56 more girls than adults.

**To find:**

The number of total persons.

**Solution:**

Let x be the number of total persons. Then,

Number of boys = [tex]\dfrac{1}{4}x[/tex]

Number of girls = [tex]\dfrac{5}{8}x[/tex]

Number of adults = Total persons - Boys - Girls

= [tex]x-\dfrac{1}{4}x-\dfrac{5}{8}x[/tex]

= [tex]\dfrac{8x-2x-5x}{8}[/tex]

= [tex]\dfrac{x}{8}[/tex]

There were 56 more girls than adults.

Girls = Adults + 56

[tex]\dfrac{5}{8}x=\dfrac{x}{8}+56[/tex]

[tex]\dfrac{5}{8}x-\dfrac{x}{8}=56[/tex]

[tex]\dfrac{4}{8}x=56[/tex]

[tex]\dfrac{1}{2}x=56[/tex]

Multiply both sides by 2.

[tex]x=112[/tex]

**Therefore, the total number of persons is 112.**

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB = 18

and AC 36, what is the length of AD?

A

D

36

18

B

**Answer:**

8 is the length

**Step-by-step explanation:**

The **length** of AD is 9 units from the given right **triangle** ABC.

A **right** angled triangle is a **triangle** with one of the angles as 90 degrees. A 90-degree angle is called a right **angle**, and hence the triangle with a right angle is called a right triangle.

Given right triangle ABC with altitude BD drawn to hypotenuse AC.

Given that, AB = 18 and AC = 36

Using **Pythagoras** theorem

AC²=AB²+BC²

⇒ 36²=18²+BC²

⇒ BC²=1296-324

⇒ BC²=972

⇒ BC=31.18 units

We know that, **area** of a triangle =1/2 × Base × Height

= 1/2 × 31.18 × 18

= 280.62 square units

Now, area of a **triangle** ABC with base AC and height BD

That is, Area = 1/2 ×36×BD

⇒ 18BD=280.62

⇒ BD=280.62/18

⇒ BD=15.6

Consider ΔBDA

AB²=AD²+BD² (Pythagoras theorem)

18²=x²+15.6²

⇒ x²=18²-15.6²

⇒ x=9 units

Therefore, the **length** of AD is 9 units from the given right **triangle** ABC.
