What’s the correct answer for this question?

Answers

Answer 1

Answer: Fourth Choice. -2

Step-by-step explanation:

Given

( -9 | 6 + ( -10 ) | ) / 2 · 3²

Expand (-10) parenthesis

= ( -9 | 6 - 10 | ) / 2 · 3²

Expand (-9|6-10|) parenthesis

= ( -9 | -4 | ) / 2 · 3²

= ( -36 ) / 2 · 3²

Simplify the denominator and get answer

= -36 / 2 · 9

= -36 / 18

= -2

Hope this helps!! :)

=32

Answer:

Step-by-step explanation:

Following PEMDAS we first do the stuff in the parentheses and we get [tex]6x4+8[/tex]

Then since there are no exponents, we go straight to doing the multiplication and division, which leaves us with [tex]24+8[/tex].

Finally when we add the last 2 terms together we get our answer of 32.

The population of a city decreases by 4% per year. If this year's population is 171,000, what will next year's population be, to the nearest individual?

Answers

How I usually find % is in the calculator I put the number im trying to find the percent of so in this case 171,000 and I multiply that by .4 in the calculator so I would put in 171,000*.4 and get 68,400 but that’s not the answer because you have to get rid of the last number so 4% of 171,000 is 6,840 then you subtract that from 171,000 and that’s your answer I got 164,160 I hope this helps :)

In a certain clothing store 6 shirts and 3 ties cost $79.50 and 3 shirts and 2 ties cost $41 determine the cost of each shirt

Answers

9514 1404 393

Answer:

$12 for each shirt

Step-by-step explanation:

If we let 's' and 't' represent the costs of a shirt and tie, respectively, then we can write the general form equations ...

6s +3t -79.50 = 0

3s +2t -41.00 = 0

The solution for s can be found using the "cross multiplication" technique.

Differences of products can be formed:

d1 = (6)(2) -(3)(3) = 3

d2 = (3)(-41) -(2)(-79.50) = 36

Then we have ...

1/d1 = s/d2 ⇒ s = d2/d1 = 36/3 = 12

The cost of each shirt is $12.00.

___

2 ties cost 41-36 = 5, so each one is $2.50.

_____

Additional comment

The use of simple elimination on this set of equations would eliminate the s-variable, so would mean additional work to find s after finding t. The t-variable could be eliminated by multiplying one equation by one coefficient, and the other by a different coefficient. As long as we're doing that amount of work, we may as well do just enough cross-multiplication to get the one answer we need. This is where the "cross-multiplication" method of solution comes in handy.

This method solves the general-form equations ...

ax +by +c = 0dx +ey +g = 0

by considering the two rows of coefficients:

a, b, c, ad, e, g, d

Then differences of cross-products are formed in adjacent columns:

d1 = ae -db

d2 = bg -ec

d3 = cd -ga

The solutions are ...

1/d1 = x/d2 = y/d3 ⇒ x = d2/d1, y = d3/d1

Answers

Answer: B

Step-by-step explanation:

The prime numbers here are outcomes 2, 3, and 5.

Therefore, we must add the frequency numbers for these prime numbers:

36 + 44 + 30 = 110

Out of 200 dice rolls, 110 were prime numbers. This can be represented as:

110/200 = 11/20 (fraction form)

= 0.55 (decimal form)

Therefore, the answer is b. 0.55

What is the equation of the line that is the perpendicular bisector of the segment
with (10,-15) and (-10, 25) as endpoints?
y= kx + 10
y= kx + 5
y= -x + 10
y = 2x + 5

Answers

Answer:

y= kx + 5

Step-by-step explanation:

Perpendicular bisector passes through the midpoint of the line.

The midpoint is:

x = (10 - 10)/2 = 0y = (-15 + 25)/2 = 5

Slope of the line:

m = (25 - (-15))/(-10 - 10) = -2

The line perpendicular to this has to have a slope of 1/2 as perpendicular lines have opposite-reciprocal slopes.

Use point-slope form and point (0, 5) to find the equation of the line:

y - 5 = 1/2(x - 0)y = 1/2x + 5

Round your answer to the nearest dollar.
Do NOT round until you have calculated the final answer.

Answers

Answer:

$6,800

Step-by-step explanation:

The interest earn after 5 years will be $6800.

It is given that Huang invests $720 into an annuity every month for five years and at end of 5 years balance was $50000.

We have to find out the interest earn.

What do you mean by interest ?

Interest is an additional amount of money that is paid by the bank to customer on the amount deposited in his account.

As per the question ;

Investment made by Huang = $720 for five years

At end of five years , account balance = $50000.

So ;

Five years = 60 months

and the investment is an annuity every month for five years.

If Huang invests $720 every month for 5 years then total investment is ;

= $720 × 60

= $43200

And account balance at end of 5 years = $ 50000

So ;

Interest earn will be ;

= $50000 - $43200

= $6800

Thus , the interest earn after 5 years will be $6800.

The mathematics faculty at a college consists of 7 professors, 4 associate professors, 4 assistant professors, and 6 instructors. If one faculty member is randomly selected, find the probability of choosing a professor or an instructor.

Answers

Answer:

0.619 = 61.9% probability of choosing a professor or an instructor.

Step-by-step explanation:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this question, we have that:

7 + 4 + 4 + 6 = 21 members

7 + 6 = 13 professors or instructors.

Find the probability of choosing a professor or an instructor.

p = 13/21 = 0.619

0.619 = 61.9% probability of choosing a professor or an instructor.

What is tree diagram?

In probability theory, tree diagrams can be used to represent probability spaces. A tree diagram can represent a set of independent events or conditional probabilities. Each node in the graph represents an event and is associated with the probability of that event.

Given,

A spinner of three sections colored green, purple and pink.

Number of outcomes = 3

spinner is spun twice,

then number of outcomes = 3 × 3 = 9

Number of branches in tree = 9

Two angle measures in a triangle are 47° and 43°. What type of triangle is it?

Also, I just wanted to say that I can only give brainliest if two people answer. Thank you!

Answers

Answer:

Right triangle

Step-by-step explanation:

Answer:

Right triangle

Step-by-step explanation:

To find the third angle, we add the two known angles.

47 + 43 = 90

The sum of all the angles of a triangle is always 180.

Therefore, we subtract 90 from 180 to find the third, unknown angle.

180 - 90 = 90

Because 90 degrees is the third angle, and 90 degrees is a right angle, this is a right triangle.
