Answers

Answer 1

Answer:

The area of the triangular case = 61.2 square inches

Step-by-step explanation:

P.S - The exact question is -

Given - Mr. Sanders wants to display his American flag in a triangular case as shown below.

To find - What is the area of the triangular case ?

Proof -

Given that,

Base of triangle = [tex]14\frac{2}{5}in[/tex]

Height of triangle = 8.5 in

We know that,

Area of triangle = [tex]\frac{1}{2}*Base*Height[/tex]

                          = [tex]\frac{1}{2}*8.5*14\frac{2}{5}[/tex]

                          = [tex]\frac{1}{2}*8.5*14.4[/tex]

                          = [tex]\frac{1}{2}*122.4[/tex]

                          = 61.2

∴ we get

The area of the triangular case = 61.2 square inches

Show work

Answers

Recall the half-angle identity,

cos²(x/2) = (1 + cos(x))/2

The angle A terminates in the fourth quadrant, so 270° < A < 360°. Then the corresponding half-angle terminates in the second quadrant, since 135° < A/2 < 180°, so cos(A/2) < 0. This means

cos(A/2) = - √((1 + cos(A))/2) = -3/4

so that

sec(A/2) = 1/cos(A/2) = -4/3.

P = 2000x

D. 16,000

Answers

9514 1404 393

Answer:

  A.  6000

Step-by-step explanation:

Use x=5 and evaluate each model.

Linear model

  P = 2000(5) = 10,000

Exponential model

  P = 500(2^5) = 500(32) = 16,000

The difference in the predicted value is ...

  16,000 -10,000 = 6,000 . . . more are predicted by the exponential model

The half-life of Palladium-100 is 4 days. After 12 days a sample of Palladium-100 has been reduced to a mass of 7 mg.

Answers

Answer:

I think this is correct but im not sure..

Step-by-step explanation:

12 days is 3 half-lives ... so, 1/8 initial ... (1/2)^3 = 1/8

... initial is 8 mg

4 weeks is 7 half-lives ... 8 mg * (1/2)^7 = ?

Answer:

56 mg

Step-by-step explanation:

Let the initial mass of sample is x mg

We have the following equation:

x* [tex](\frac{1}{2}) ^{12/4}[/tex]= 7x*[tex](\frac{1}{2}) ^{3}[/tex] = 7x*[tex](\frac{1}{8} )[/tex] = 7x = 7*8x = 56 mg

Auntie Sammy buys a hand bag. There was a discount
of 20%.
If Auntie Sammy paid $245, what was the original price?

Answers

Answer:

Step-by-step explanation:

I think the original proce would be  $265

1. Subtract the percentage discount from 100

100 - 20= 80

2. Multiply the final price($245) by 100

245 × 100= 24,500

3. Divide the answer in step 2 by the answer in Step 1

24,500 ÷ 80= $306.25

answer is $306.25

How to check to ensure your answer is correct:

1. Multiply the "answer" by the discount price divided by 100. This will give the discount percentage in dollars.

$306.25 × 0.2( which is 20÷100)= $61.25(discount in dollars)

2. Subtract the discount in dollars from the "answer"

$306.25 - $61.25= $245(final price is the same as in the problem so it is correct)

OR

1. Multiply the original price by the number you get from step 1 in your problem divided by 100

$306.25 × 0.8(80 from the very first step divided by 100)= $245(the final price is the same given in the question)

|x- 13| - 5= -5

Answers

Answer: x=13

Step-by-step explanation: Hope this help :D

Answer:

One Solution

__________

x = 13

__________

Explanation:

| x – 13 | – 5 = -5

[Add 5 to both sides to isolate | x – 13 | and cancel out –5]

| x – 13 | – 5 + 5 = -5 + 5

[Reduce]

| x – 13 | = 0

[An absolute value can include both a positive and negative value so |x| = n → x = ±n ]

x – 13 = ± 0

[Add 13 to both sides to get the value of x]

x – 13 + 13 = 13 ± 0

x = 13 ± 0

[Adding or subtracting zero will leave you with the same number]

x = 13
