Answer 2

Answer:

x= 1

Step-by-step explanation:

Add four to both sides of the equation:

10x-4+4 = 2x+4+4

Simplify:

10x = 2x+8

Subtract 2x from both sides:

8x = 8

Cancel out terms:

Simplify:

x=1

The amount of a radioactive isotope decays in half every year. The amount of the isotope can be modeled by f(x) = 346(one half)x and f(1) = 173. What does the 173 represent?

Answers

9514 1404 393

Answer:

f(1) = 173 = the amount remaining after 1 year

Step-by-step explanation:

The function definition tells you f(x) is the amount of the isotope remaining after x years. Then ...

f(1) = 173 = the amount remaining after 1 year

(no units are given, so we don't know if that is 173 nanograms, or 173 truck loads)

You deposit $2000 in an account that pays 7% interest compounded semiannually. After 5 years, the interest rate is increased to 7.28% compounded quarterly. What will be the value of the account after a total of 10 years?

The value of the account will be $_____. (Round to the nearest dollar as needed.)

Answers

9514 1404 393

Answer:

$4047

Step-by-step explanation:

For an interest rate r compounded n times per year for t years, the effective multiplier is ...

(1 +r/n)^(nt)

The multiplier for the first 5 years is ...

(1 +0.07/2)^(2·5) = 1.41059876

The multiplier for the last 5 years is ...

(1 +0.0728/4)^(4·5) = 1.43437218

Then the account value at the end of 10 years is ...

$2000(1.41059876)(1.43437218) ≈ $4047 . . . . balance after 10 years

Answers

Answer:

78°

Step-by-step explanation:

From the diagram,

Applying sine rule,

SinA/a = sinC/c................... Equation 1

Given: c = 29 cm, C = 50°, a = 37 cm

Substitute into equation 1 and solve for A.

sinA/37 = sin50°/29

sinA = (37×sin50°)/29

sinA = (37×0.766)/29

sinA = 28.34/29

sinA = 0.9774

A = sin⁻¹(0.9774)

A = 77.8°

A ≈ 78°

Hence the measure of angle A = 78°

Answer:

number B (4×4)+(3×3×3)= 43

Answer:

B. 4² + 3³

Step-by-step explanation:

I'll do each of these expression to see which one equals 43.

2⁴ + 3²

16 + 9

25 ≠ 43; So A is out.

5² + 5³

25 + 125

150 ≠ 43; so C is out.

3² + 2³

9 + 8

17 ≠ 43; so D is out.

4² + 3³

16 + 27

43 = 43, so B is the answer to this question.

can someone pls help me. it’s marked as late work and i don’t understand how to do
it. the question says “find the surface area of the rectangular prism” if you help i’ll mark u as brainlest tysm

Answers

So how you would answer this question is by finding the area of the sides. So the rectangle is 25 x 17 or 425 and there is 4 rectangles. You take the area of the rectangle and multiply it by 4, which would be 1700 and now you find the area of the square which is 17 x 17 or 289 and then you multiply that by 2 because there are two squares, 578 and you take that answer and put it with the area of the rectangles and you get your surface area. 2278 is the surface area of the rectangular prism. Another way to explain it is there are 6 sides so six areas and you just add the areas together to get the surface area. Hope this helps :D

A movie complex is showing the same movie in three theaters. In theater A, 44 of the 80 seats are taken. In theater B, 42 seats are taken and 28 seats are empty. In theater C, 27 of the 90 seats are empty. Which theater has the greatest percent of its seats taken? Which theater has the greatest of its seats taken ?

Answers

Answer:

Theater C

Step-by-step explanation:

Theater A has 80 seats, 44 of which are taken. 44/80 can be simplified to 11/20, which is 0.55 in decimal form, and 55% in percent form.

Theater B has 70 seats, because 42+28 = 70. 42 of those 70 seats are taken. 42/70 is 60%

Theater C has 90 seats, and because 27 are empty, we can subtract 27 from 90, which leaves us at 63 seats are taken. 63/70 is 70%

70% is the biggest percentage, so Theater C has the greatest seats taken.

I hope this helps! :))
