r = 0.15

n = 12

$544.61  (to the nearest cent)

[tex]P(1+r)^t[/tex]

$524.70  (to the nearest cent)

Step-by-step explanation:

P = principal amount = $300

r = annual interest rate in decimal form = 15% = 15/100 = 0.15

n = number of times interest is compounded per unit t = 12

How much she'll owe in 4 years

P = 300

n = 12

t = 4

[tex]P(1+\frac{r}{n})^{nt}=300(1+\frac{0.15}{12})^{12 \times 4}[/tex]

= $544.61  (to the nearest cent)

Yearly compounding interest rate

[tex]P(1+r)^t[/tex]

How much she'll owe in 4 years at yearly compounding interest

Answer: 71x+85y=4904

Step-by-step explanation:

a) 3x + 5y = 8

4x - 3y = 1

• using the elimination method:

3x + 5y = 8 (×4)

4x -3y = 1 (×3)

12x + 20y = 32

12x -9y = 3

subract 12x from both equation:

20y - - 9y= 32 -3

20y +9y = 29

29y= 29

y= 29/29

y= 1

- substituting y= 1 in :

4x - 3y= 1

4x - 3(1) = 1

4x -3 = 1

4x = 1 + 3

x = 4/4

x= 1

b) 6p+ 4q = 20

5p - 2q = 6

• using the elimination method:

6p + 4q = 20

5p - 2q = 6 (×2)

6p + 4q = 20

10p - 4q = 12

add 4q + -4q to eliminate q.

6p+ 10p = 20+12

16p = 32

p = 32/ 16

p = 2

- subtituting p = 2 in :

5p - 2q = 6

5(2) -2q =6

10 -2q = 6

-2q = 6 - 10

q = -4 / -2

q = 2

Step-by-step explanation:

Triangles ADB, ABC and BDC are similar.

Therefore, we can use ratios to find BD.

Using the ratio of the long leg to the short leg of ΔBDC and ΔADB:

[tex]\dfrac{BD}{16}=\dfrac{4}{BD}[/tex]

Cross multiply and solve for BD:

[tex]\implies BD^2=4 \times 16[/tex]

4- There is no h-intercept/zero

All the real numbers are the domain of the function. Then the range of the function will be [16π, ∞).

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The domain means all the possible values of x and the range means all the possible values of y.

The equation that represents the surface area of the paper cup is given below.

S(h) = 4π√(16 + h²)

Where h is the height of the cup.

The graph of the equation is drawn below. Then all the real numbers are the domain of the function.

And the lowest point of the function will be given as,

S(0) = 4π√(16 + 0²)

S(0) = 4π√16

S(0) = 16π

Then the range of the function will be [16π, ∞).

Answer:

36 times.

Step-by-step explanation:

3/5=0.6

2/5=0.4

60*0.6=36

Scott would expect the wad of paper to land in the trash can approximately 36 times out of 60 throws. So, correct option is B.

To calculate the expected number of times the wad of paper would land in the trash can if Scott throws it 60 times, we can use the concept of probability.

Based on the given results, the probability of the wad of paper landing in the trash can is 3 out of 5 times (3 times in the trash can out of a total of 5 throws).

To find the expected number of successful throws (i.e., landing in the trash can) out of 60 throws, we can set up a proportion:

(Probability of success) = (Number of successful throws) / (Total number of throws)

3/5 = x/60

Now, cross-multiply and solve for 'x':

5x = 3 * 60

5x = 180

x = 180 / 5

x = 36

The correct answer is B. 36

This calculation is based on the assumption that the probability remains the same for each throw, which is the case for independent events like tossing a wad of paper.

Answer:

y = 68

z = 138

Step-by-step explanation:

Use triangle ACD.

m<A m<C + m<ADC = 180

y + 70 + 42 = 180

y + 112 = 180

y = 68

Use parallel lines BF and CE.
