Four boards were given to Sam to build a triangular picture frame for a large painting.
32 feet
21 feet
8 feet
12 feet
Which of these boards could be used for his project?

Answers

Answer 1

The sum of any two sides of a triangle must be greater than the other thus 32 feet,21 feet, and 12 feet will be the correct so options (A),(B), and (D) are correct.

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

As per the given,

To be a triangle of three side polygon the sum of any two sides must be greater than the third side.

If we take 32 feet,21 feet, and 8 feet.

21 + 8 = 29 < 32 so it will not form any triangle.

Thus, 8 cannot be taken. now let's take 32,21 and 12 here 21 + 12 = 33 > 32 so it will form a triangle this will be used for the project.

Hence "The right answer will be 32 feet, 21 feet, and 12 feet because the sum of any two sides of a triangle must be bigger than the other".

How much compound interest will $50,000 have earned in 10 years at
6.4% annual interest compounded quarterly?

Answers

Answer:

Step-by-step explanation:

To find the compound interest earned on $50,000 in 10 years at 6.4% annual interest compounded quarterly, we can use the formula:

compound interest = principal * (1 + rate/n)^(n*t) - principal

where "principal" is the initial amount of money, "rate" is the annual interest rate, "n" is the number of times the interest is compounded per year, and "t" is the number of years.

Plugging in the given values, we get:

compound interest = $50,000 * (1 + 0.064/4)^(4*10) - $50,000

= $50,000 * (1.016)^40 - $50,000

= $50,000 * 2.6335 - $50,000

= $78,167.50 - $50,000

= $28,167.50

Therefore, the compound interest earned on $50,000 in 10 years at 6.4% annual interest compounded quarterly is $28,167.50.

question is in the image, i need the method answer for part b.

the question says: "the diagram shows the position of two ships, A and B, and the coastguard station, C."

Answers

Step-by-step explanation:

it seems like you understood the law of cosine (extended Pythagoras for non-right-angled triangles) and applied it mostly correctly for a).

but you made a little typo : suddenly, in the second half of the formula you changed the side length BC from 83.1 to 81.3. but it is 83.1.

so, the correct calculation is

a² = 83.1² + 95.5² - 2×95.5×83.1×cos(101) =

= 16,025.86 - 15,872.1×cos(101) =

= 16,025.86 - -3,028.539456... =

= 19,054.39946...

a = sqrt(19,054.39946) = 138.037674...

the rounded result is the same (138 km), but just for your information, and also, I want to use the correct numbers for b)

for b) we need to know :

bearings are angles, measured clockwise from north (north would be 0°).

when ship A looks to station C, the bearing is 146°.

when ship A looks to ship B, the corresponding bearing is 146 - the triangle angle at A (because that is how far we have to turn from looking at C to looking at B).

so, now, we need to apply the law of cosine again. this time to get angle A, as we have now side a.

c² = a² + b² - 2ab×cos(C)

and we want to get C, means now (since you called the baseline "a" in the first part)

83.1² = 95.5² + a² - 2×a×95.5×cos(angle A)

6,905.61 = 9,120.25 + 19,054.39946... - 2×138.037674...×95.5×cos(angle A)

6,905.61 = 28,174.64946... - 26,365.19574...×cos(angle A)

-21,269.03946... = -26,365.19574...×cos(angle A)

cos(angle A) = -21,269.03946.../-26,365.19574...

= 0.806708953...

angle A = 36.22437773...°

therefore, the bearing from A to B is

146 - 36.22437773... = 109.7756223...°

A decline in net income is a change from one period to the next in the amount of money you have after deducting your expenses from your revenues.

How do you calculate the net?

There are two possible outcomes for net income. Your business has a positive net income when revenues exceed expenses. You have a negative net income, commonly referred to as a net loss, if all of your expenses exceed all of your revenues.

let the number is x

first it is increased by 25%

so,

x+(25/100)x=(125/100)x

now according to second condition,

we have to find a value by which it is decreased so we get the same number.

so, let that decreased value is y;

(125/100)x-y=x

-y=x-(125/100)x

Answers

Answer If O, P, and Q are collinear points with PQ = 3, and P' and Q' are the images of P and Q under dilation from O with a scale factor of 4, then the length of the segment P'Q' will be 4 times the length of the segment PQ. Since PQ = 3, the length of P'Q' will be 4 * 3 = $\boxed{12}$.

To see why this is the case, recall that a dilation with a scale factor of 4 expands or contracts a figure by a factor of 4 in each direction. In this case, the dilation from O with a scale factor of 4 expands the segment PQ by a factor of 4, resulting in the segment P'Q' with a length of 4 times the length of PQ. Since PQ = 3, the length of P'Q' will be 4 * 3 = 12.

Answer: No, because they are not the same in slope - intercept form

Step-by-step explanation:

    First, we will distribute and simplify into slope-intercept form.

   Equation 1:

y - 3 = 4(x - 2)

y = 4(x - 2) + 3

y = 4x - 8 + 3

y = 4x - 5

   Equation 2:

y + 2 = 4(x + 7)

y = 4(x + 7) - 2

y = 4x + 28 - 2

y = 4x + 26

      We see that the answer to this question is "No, because they are not the same in slope - intercept form" as they have different y-intercepts, one being -5 and one being 26.

perimeter is 84 cm, find the dimensions of the triangle.

Answers

Answer:

7 cm.

The triangle dimensions are:  50, 27, and 7 cm

Step-by-step explanation:

The three sides of the triangle make up the entire perimeter.  Add each side and set the result equal to 84cm, the perimeter.

(7x+1) + (4x-1) + (14-x) = 84 cm

10x + 14 = 84

10x = 70

 x = 7 cm

Use x=7 to find the three dimensions:

1)  (7x+1) = 50 cm

2)  (4x-1) = 27 cm

3)  (14-x) = 7 cm

Do these add to 84 cm?

 (50+27+7) = 84 cm  YES

Answers

Assuming that costs increase linearly with the number of attendees, Patricia needs at least 30 people to attend the forum in order to break even.

Patricia needs 75 attendees to attend the forum in order to make a profit of 337,500.

By dividing the fixed costs by the contribution margin per unit, we are able to determine the break-even threshold in units. Divide the fixed costs by the contribution margin ratio to get the break-even threshold in dollars.

The percentage of the contribution margin to the sales revenue is known as the contribution margin ratio. Prior to the division operation, we add

the profit to the fixed cost in order to reach the goal profit.

Billing rate per participant = 10,000

Hotel charges per participant = 2,500

Contribution per participant = 7,500 (10,000 - 2,500)

225,000 is the fixed fee for the hotel room and amenities.

Break-even point in units = Contribution per unit – Fixed cost

= 30 individuals (225,000 -7,500)

Fixed cost plus profit minus contribution per unit equals break-even point in units with target profit.

Target profit = 337,500

= (225,000 + 337,500) ÷ 7,500

Answers

The total flowers in the garden white or pink is 8/15.

What is fraction?

The components of a whole or group of items are represented by fractions. A fraction consists of two components. The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection. The denominator is the figure that appears below the line.

In our garden, there are 2/3 total roses, making the total number of blooms that aren't roses 1/3

4/5 = 2/3 +1/3.

Since 3 is a division of 6, we must multiply by 6 to arrive at the solution.

4 x 6 =24

5 x 6 =30

24/30

Next, we calculate half of 30 and add it to get 3/3.

Then we find 1/2 of 30 and add this to make 3/3

Just like 1/2 of 2 = 1 and 2+1 = 3

30 / 2  = 15

15 + 30 =45

The answer is 24/45

We then reduce this fraction by 3 as 6 + 8 do not divide into 45

24/45 = 8/15

The total flower in the garden is 8/15

The proportion of white or pink flowers in the entire garden is 8/15.
