A triangle has an area of 12 square units and a height of 8 units. Find its base.

Answers

Answer 1

Answer:

3

Step-by-step explanation:

b= 2 [tex]\frac{A}{Hb}\\[/tex] =   2 · [tex]\frac{12}{8}[/tex] = 3

Answer 2

Answer:

base= 3

Step-by-step explanation:

You need to work backwards to solve this problem

A= 1/2bh

with the information given, the equation should look like this:

12= 1/2b8

To get rid of the fraction, you flip it, and you multiply both sides by that (1/2 fliped is 2)

so  2* 12= 1/2b8 *2

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

** You can see that the 1/2 and the two cancel each other out. This is why:

1/2* 2/1= 2/2

2/2=1

1 * b8 is just b8

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

So now you have:

24= b8

you want to get b by itself, so you use inverse operations ( you divide both sides by 8)

24/8= b8/8

your final answer is 3=b

you can plug in 3 into the original equation to check your answer!!!

[tex]2a { }^{2} b {}^{2} - 7ab - 30[/tex]

Answers

Answer:

(ab - 6)(2ab + 5)

Step-by-step explanation:

Assuming you require the expression factorised.

2a²b² - 7ab - 30

Consider the factors of the product of the coefficient of the a²b² term and the constant term which sum to give the coefficient of the ab- term

product = 2 × - 30 = - 60 and sum = - 7

The factors are - 12 and + 5

Use these factors to split the ab- term

= 2a²b² - 12ab + 5ab - 30 ( factor the first/second and third/fourth terms )

= 2ab(ab - 6) + 5(ab - 6) ← factor out (ab - 6) from each term

= (ab - 6)(2ab + 5) ← in factored form

A store is holding a grand opening promotion. Every 3rd customer receives a free key chain and every 4th customer receives a free magnet. Which customer will be in the first to receive both a key chain and a magnet?

Answers

Answer:

12th Customer

Step-by-step explanation:

We have to find the lcm (lowest common multiple) of the number.

We do that by taking their multiples. Watch down below

3 x 1 = 3                4 x 1 = 4

3 x 2 = 6               4 x 2 = 8

3 x 3 = 9               4 x 3 = 12

3 x 4 = 12

See how they both have a 12 as their first lcm.

So the 12th customer gets both items.

A banker earns a $75,000 annual salary, a 2.35% commission on any approved loans for the bank’s business customers, and a fee of $3.75 for each application processed. If the banker has a total of $2.8 million in approved business loans and processes 2,750 applications this year, what are the banker’s earnings rounded to the nearest dollar?

Answers

Answer:

Amount earned = $151,113

Step-by-step explanation:

Here, we are interested in calculating the banker’s earnings rounded to the nearest dollar;

We proceed as follows; we have the following;

1. Annual salary of $75,000

2. 2.35% on approved loans.

Approved loans = 2.8 million

Commission = 2.35/100 * 2.8 million = $65,800

3. $3.75 for each processed loan application

Total = 2750

Amount = 3.75 * 2750 = $10,312.50

Total amount earned is thus;

$75,000 + $65,800 + $10,312.50 = 151,112.5 = 151,113 to the nearest dollar

Answers

Answer:

Option (4)

Step-by-step explanation:

It has been given in the question that angle 1 is supplementary to angle 4.

m∠1 + m∠4 = 180°

∠2 and ∠3 are the interior consecutive angles.

Since, same side of the theorem says "Exterior angles formed on the same side of the parallel lines and the transversal line are supplementary".

Therefore, by converse of the same side Exterior angles theorem 'a' and 'b' will be parallel.

Option (4) will be the answer.

What is the equation of a perpendicular line?

If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m. The equation is in the form of slope-intercept form. Then the equation of the line is given as

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The equation of the line is given as,

12x + 2y = - 12

Convert the equation in the slope-intercept form, then the equation will be given as,

Separate the variable y, then the equation is given as,

6x + y = - 12

y = -6x - 12

The slope of the line is - 6. Then the slope of the perpendicular line will be 1/6.

In January, a city’s snowfall was 5/8 foot below the historical average. In February, the snowfall was 3/4 foot above the historical average. Was the city’s snowfall in the two-month period above or below the historical average? By how much?

Answers

Answer:

The city's snowfall in the two-month period was above the historical average by 1/8 feet

Step-by-step explanation:

Fractions

The question provides the following information: In January, a city’s snowfall was 5/8 feet below the historical average. Let's assume the snowfall level to be positive if it's above the historical average and negative otherwise.

The data from January gives us a snowfall of -5/8 feet because it was below the average.

We also know in February, the snowfall was 3/4 foot above the historical average. Following our predefined convention, the data from February gives us a snowfall of +3/4 feet.

To know if the city's snowfall during the two-month period was above or below the historical average, we just need to add them, signs included.

If the result is negative, the two-month period showed a snowfall below the historical average.

Let's find the sum of

[tex]\displaystyle -\frac{5}{8}+\frac{3}{4}[/tex]

The LCM of 4 and 8 is 8, thus:

[tex]\displaystyle -\frac{5}{8}+\frac{3}{4}=\frac{-5+2*3}{8}=\frac{1}{8}[/tex]

Since this quantity is positive, we can say the city's snowfall in the two-month period was above the historical average by 1/8 feet.
