The base of a triangle is nine centimeters longer than the perpendicular height. If the area of the triangle is 180 square centimeters, what is the length of the base, in centimeters?

Answers

Answer 1

Answer:

The base is 24 cm long.

Step-by-step explanation:

Equations

Let's call

b= base of the triangle

h=height of the triangle

The base is 9 cm longer than the height, thus:

b = h + 9

The area of the triangle is:

[tex]\displaystyle A=\frac{bh}{2}[/tex]

[tex]\displaystyle A=\frac{(h+9)h}{2}[/tex]

And its value is 180:

[tex]\displaystyle \frac{(h+9)h}{2}=180[/tex]

Multiplying by 2:

[tex](h+9)h=360[/tex]

Operating:

[tex]h^2+9h-360=0[/tex]

Factoring:

[tex](h-15)(h+24)=0[/tex]

The only valid positive solution is:

h = 15 cm

And b = h + 9 = 24

b = 24 cm

The base is 24 cm long.

A line passes through the points (8, 1) and (6, 7). What is the slope?



Answers

Answer:

-3

Step-by-step explanation:

7-1=6

6-8=-2

A line connects the points (8, 1) and (6, 7). The angle is -3.

What is meant by slope?The slope or slope of a line is a number in mathematics that describes both the direction and slope of a line. Gradients are frequently represented by the letter m.There is no clear reason why the letter m is used for gradients, but it was first used in English by O'Brien (1844), who wrote the equation for a straight line as "y = mx + b."He is also depicted in Tod Hunter's (1888) work, where he wrote "y = mx + c."The slope is calculated by dividing the difference between two (arbitrary) points on a line by the ratio of vertical and horizontal change.

Therefore,

Slope (m) = ΔY/ΔX

= 3/-1

= -3

The slope =  -3

θ = arctan(ΔY/ΔX) + 180°

=1 08.43494882292°

ΔX = 6 – 8 = -2

ΔY = 7 – 1 = 6

Distance (d) = √ΔX2 + ΔY2 = √40 = 6.3245553203368

Equation of the line:

y = -3x + 25

When x = 0, y = 25

When y = 0, x = 8.3333333333333

Hence,  A line connects the points (8, 1) and (6, 7). The angle is -3.

Which reason justifies statement 2?

A) Vertical angles are congruent

B) Corresponding angles are congruent

C) Alternate interior angles are congruent

D) Alternate exterior angles are congruent

Answers

Answer:

C. Alternate interior angles are congruent

Step-by-step explanation:

<Y and <4 are two alternate angles within the two parallel lines cut across by the transversal, hence, they are called alternate interior angles.

Alternate interior angles are always congruent to each other. Therefore, the reason that justifies statement two: "<Y ≅ <4", is "Alternate interior angles are congruent".

A chef at a restaurant uses 17 pounds of butter each day. About how many grams does the chef use each day?

Answers

answer

7711.07

Step-by-step explanation:

The chef uses 7,711.03 grams each day at a restaurant.

How to convert Pounds to Grams?

The methodology to convert Pounds to Grams is relatively simple. To convert Pounds to Grams, you must multiply the unit by 453.59.

For example, if you have to convert 5 Pounds to Grams, you need to multiply 5 by 453.59.

A chef at a restaurant uses 17 pounds of butter each day.

We have to determine the number of grams the chef uses each day.

Since 1 pound (lb) is equal to 453.59 grams (g).

So 17 pounds = 453.59 × 17 = 7,711.03 grams

Thus, the chef uses 7,711.03 grams each day.

The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y - 4 = (x – 8). What
is the slope-intercept form of the equation for this line?
O y = 1 x - 12
O y = -x-4
O y=+*+2
O y=x+6

Answers

Answer: y = x/4 + 2

Y equals one fourth x plus two.

Step-by-step explanation:

There seems to be a typo on answer choice c.

Slope intercept form is y= mx + b

m is the slope. b is the y-intercept.

The y-intercept is given here in the coordinate (0,2) It is +2

Slope is rise/run.

Rise: Difference in given y-values is 4-2 = 2.

Run: Difference in x-values is 8-0=8.

So the slope is 2/8 = 1/4

The equation is y = 1/4 x + 2

Life coaches, business coaches, We may or may not take them seriously, but we must know something. Most, if not all of them, be it famous ones or not-so-famous ones, agree at one valuable point: goals are crucial. Short-term as well as long-term goals are the key the achieving a more successful life.What professionals such as Tony Robbins claim is that having goals will provide you with a direction in life. The steps you take will gain value as to whether or not they take you any closer to those goals. If they dont, the best thing to do would be to evaluate how they can be changed or even left out and substituted for more efficient ones. Robbins, continually tells the story of how he wrote down every single thing he wanted to achieve in life along with the actions he would take to do so and how he did indeed achieve all of those things.When it comes to landing that beautiful and profitable a dream job, setting a long-term goal can undoubtedly direct your actions. If you choose to focus only on the short-term aspects of work and professional development, odds are that you will end up near-sighted. You will only work hard at things that can bring you immediate compensation. Those things are not naturally going to land the dream job. They will keep you alive, pay bills, and buy some food, but wont necessarily satisfy the requisites to get to the top, whatever that can mean to you.If you do choose to have a long-term goal that is dream-job related, the chances are that you will choose different paths. You will not see that ten-month course as a waste of time, since it will give you useful skills. You will spend your money more wisely, viewing it more as an investment than as a necessary evil. You will gain a new perspective of what time means and develop the sense that immediacy is overrated.There are those who call themselves realistic or, more honestly, pessimistic. They may claim that setting long-term goals is nothing but a recipe to feeling like a failure. Truth be told, it is indeed possible that you wont achieve every single thing you wish for, which is actually in most cases for us that we don't necessarily achieve our every goal. It might be our lack of willpower or that our goal was just not engineered very well. So that is a reality not only for you but for everyone else on this planet. However, not achieving something should not be a synonym for failure. It can mean some rethinking is important, some assessing needs to be done, a new plan should be concocted. Great minds goals, such as Elon Musk, are not only long term but also ambitious. And if they fail on their way, they find the means to try again, now with improved knowledge from the previously failed experience.Tony Robbins says that most people overestimate what they can do in a year, and underestimate what they can do in a decade. That is the real recipe for failure: seeing time as a factor of stress and pressure instead of an ally. By giving yourself a grand goal and a good amount of time to do it such as landing the dream job in five to ten years, you are being more realistic than you would be by either giving up altogether or trying to do it impossibly quickly. Landing a dream job takes time and effort, but as long as you set good reasonable goals, you can accomplice almost anything.
