Astronomers sometimes use angle measures divided into degrees, minutes, and seconds. One degree is equal to 60 minutes, and one minute is equal to 60 seconds. Suppose that angleJ and angleK are complementary, and that the measure of angleJ is 49 degrees, 28 minutes, 21 seconds. What is the measure of angleK?


The measure of angleK is degrees, minutes, and seconds.

Answer:

Future value, A = $10,500

Step-by-step explanation:

Given the following data;

Principal = Rs. 10,000

Interest rate compounded half yearly = 10% = 10/2 = 5%

Time = 1 year

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{100})^{t}[/tex]

Where;

Substituting into the equation, we have;

[tex] A = 10000(1 + \frac{5}{100})^{1}[/tex]

[tex] A = 10000(1 + 0.05)[/tex]

[tex] A = 10000(1.05)[/tex]

Future value, A = $10,500

Answer:

[tex]C(t) = 85(1.046)^t[/tex], and the correct answer is given by option g.

Step-by-step explanation:

Equation for an concentration increasing exponentially:

The concentration after t years, considering that it increases exponentially, is given by the following equation:

[tex]C(t) = C(0)(1 + r)^t[/tex]

In which C(0) is the initial concentration and r is the growth rate, as a decimal.

The concentration of a pollutant in a lake is 85 parts per million (ppm) and is increasing at a rate of 4.6% each year.

This means that [tex]A(0) = 85, r = 0.046[/tex]. Thus

[tex]C(t) = C(0)(1 + r)^t[/tex]

[tex]C(t) = 85(1 + 0.046)^t[/tex]

[tex]C(t) = 85(1.046)^t[/tex], and the correct answer is given by option g.

Answer:

B). F(1, 12) = 16.00

Step-by-step explanation:

'ANOVA' is a measure employed for 'analysis of a variance' in a given set of data of treatments or populations. While t-test helps in comparing their means.

As per the question, the F-ratio using ANOVA would be 'F(1, 12) = 16.00.' In order to calculate the variances, the distinction among the samples. The б^2 denotes the difference of representative means which is augmented by n(in case of samples being same). So, the ratio of F(1, 12) would be б^2 i.e. 4^2 = 16 since the sample sizes are distinct. Thus, option B is the correct answer.

Answer:

4082

Step-by-step explanation:

Given

The composite object

Required

The volume

The object is a mix of a cone and a hemisphere

Such that:

Cone

[tex]r = 10cm[/tex] ---- radius (r = 20/2)

[tex]h = 19cm[/tex]

Hemisphere

[tex]r=10cm[/tex]

The volume of the cone is:

[tex]V_1 = \frac{1}{3}\pi r^2h[/tex]

[tex]V_1 = \frac{1}{3}\pi * 10^2 * 19[/tex]

[tex]V_1 = \frac{1900}{3}\pi[/tex]

The volume of the hemisphere is:

[tex]V_2 = \frac{2}{3}\pi r^3[/tex]

[tex]V_2 = \frac{2}{3}\pi 10^3[/tex]

[tex]V_2 = \frac{2000}{3}\pi[/tex]

So, the volume of the object is:

[tex]V = V_1 + V_2[/tex]

[tex]V = \frac{1900}{3}\pi + \frac{2000}{3}\pi[/tex]

[tex]V = \frac{3900}{3}\pi[/tex]

[tex]V = 1300\pi[/tex]

[tex]V = 1300 * 3.14[/tex]

[tex]V = 4082[/tex]

Answer:

Volume of cylinder = 192π inch³

Step-by-step explanation:

Given:

Diameter of base = 8 inch

Length of cylinder = 12 inch

Find:

Volume of cylinder

Computation:

Radius of cylinder = Diameter of base / 2

Radius of cylinder = 8 / 2

Radius of cylinder = 4 inch

Volume of cylinder = πr²h

Volume of cylinder = π(4)²(12)

Volume of cylinder = π(16)(12)

Volume of cylinder = 192π inch³

Answer:

101

Step-by-step explanation:

Angles 1 and 2 together equal 180, Angle 1 is 79 therefore

180 = Angle 1 + Angle 2

180 = 79 + Angle 2

180 - 79 = Angle 2

Step-by-step explanation:

Pythagorean Theorem:

a² + b² = c²

Input:

2² + x² = 5²

Remember, c² is always the side opposite of the right angle...

4 + x² = 25

21 = x²

Answer:

[tex]\sqrt{21}[/tex]

Step-by-step explanation:

let the missing side be x , then

Using Pythagoras' identity in the right triangle.

x² + 2² = 5²

x² + 4 = 25 ( subtract 4 from both sides )

x² = 21 ( take the square root of both sides )

x = [tex]\sqrt{21}[/tex] ≈ 4.6 ( to 1 dec. place )

Answer:

angle A=54 degree

angle B =36 degree

Step-by-step explanation:

let angle B be x

angle A=x+18

since they are complementary angles sum of these two angles will be 90 degree

x+x+18=90

2x=90-18

2x=72

x=72/2

x=36 degree

substitute the value of x to find angle A and angle B

for angle A

x+18

36+18

54 degree

for angle B

angle B =x

=36 degree
