There are six $5 bills and nine $10 bills

Step-by-step explanation:

x= $5 bills

y= $10 bills

Find the volume of a right circular cone that has a height of 9.7 ft and a base with a radius of 7.6 ft. Round your answer to the nearest tenth of a cubic foot.

Answers

Answer:

586.7 ft^3

Step-by-step explanation:

1) find the base area

base area = radius^2 x pi = 7.6^2 x pi = 181,458392 ft^2

2) find the volume

V = (base area x height)/3 = (181,458392 x 9.7)/3 = 586.7 ft^3


12. From the top A of a building 125m above a street, the angle of elevation of the top B of a second
building on the opposite side is 18'36'and the angle of depression of the base of the second building
from A is 39° 48
(a) Calculate the width of the street​

Answers

Answer: 150.02 m

Step-by-step explanation:

Given

The height of building A is 125 m

the angle of elevation to the top of building B is [tex]18^{\circ}36'[/tex]

and the angle of depression of the base of Building B is [tex]39^{\circ}48'[/tex]

Suppose the width of the street is x

from the figure, we can write

[tex]\Rightarrow \tan (39^{\circ}48')=\dfrac{125}{x}\\\\\Rightarrow \tan (39.8^{\circ})=\dfrac{125}{x}\\\\\Rightarrow x=\dfrac{125}{\tan 39.8^{\circ}}\\\\\Rightarrow x=150.02\ m[/tex]

Thus, the width of the street is [tex]150.02\ m[/tex]

Enter a positive value for k that makes this statement true 20 times k is less than 20 but greater than o

Answers

Answer:

Step-by-step explanation:

If we're asked to use any positive value. It means we could have a wide variety of answer. A positive value of k that makes the equation 20k to be less than 20, yet greater than zero has to be any decimal value or a fraction, if you so wish.

As an example, if k is 0.5. Then we have

20k = 20 * 0.5 = 10, which is less than 20 and greater than zero

Again, if k is 0.9. Then we have

20k = 20 * 0.9 = 18, which is less than 20 and greater than zero.

So, you use any decimal number greater than 0, yet less than 1


Line KJ represents a proportional relationship. Point K lies at (12,14) as shown on the graph below.

Which ordered pair could represent the coordinates of point J?

Answers

Given:

Line KJ represents a proportional relationship.

Point K lies at (12,14).

To find:

The ordered pair of the coordinates of point J.

Solution:

If y is proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

[tex]\dfrac{y}{x}=k[/tex]

Where, k is the constant of proportionality.

It means, the ratios of y to x for all the point in a proportional relationship are same.

Line KJ represents a proportional relationship. Point K lies at (12,14).

So, the constant of proportionality is:

[tex]k=\dfrac{14}{12}[/tex]

[tex]k=\dfrac{7}{6}[/tex]

Similarly, find the ratio of y to x for all given points.

In option a,

[tex]\dfrac{3.5}{3}=\dfrac{3.5\times 2}{3\times 2}[/tex]

[tex]\dfrac{3.5}{3}=\dfrac{7}{6}[/tex]

In option b,

[tex]\dfrac{15}{17.5}=\dfrac{15\times 2}{17.5\times 2}[/tex]

[tex]\dfrac{15}{17.5}=\dfrac{30}{35}[/tex]

[tex]\dfrac{15}{17.5}=\dfrac{6}{7}[/tex]

In option c,

[tex]\dfrac{0}{2}=0[/tex]

In option d,

[tex]\dfrac{3}{3.5}=\dfrac{3\times 2}{3.5\times 2}[/tex]

[tex]\dfrac{3}{3.5}=\dfrac{6}{7}[/tex]

The ratio of y to x of point (3,3.5) is equal to the ratio of given point K(12,14). So, the coordinates of point J are (3,3.5).

Therefore, the correct option is A.

Answers

Answer:

Step-by-step explanation:

Answer:

405 in^2

Step-by-step explanation:

Given data

Height= 27in

Circumference= 47.1 in

let us find the radius and the diameter of the base of the cylinder

from

C=2πr

47.1= 2*3.142*r

47.1= 6.284r

r= 47.1/6.284

r= 7.5 in

Diameter= 2r

D= 7.5*2

D= 15in

Hence the area of the cross-section

=H*D

=27*15

=405 in^2

Step-by-step explanation:

........................

Answer:

(10111)2 = (23)10

Step by step solution

Step 1: Write down the binary number:

10111

Step 2: Multiply each digit of the binary number by the corresponding power of two:

1x24 + 0x23 + 1x22 + 1x21 + 1x20

Step 3: Solve the powers:

1x16 + 0x8 + 1x4 + 1x2 + 1x1 = 16 + 0 + 4 + 2 + 1

Step 4: Add up the numbers written above:

16 + 0 + 4 + 2 + 1 = 23.

So, 23 is the decimal equivalent of the binary number 10111.

What is right triangle ?

Right triangle is a triangle in which one angle is of [tex]90^0[/tex].

We have,

Hypotenuse [tex]=18[/tex] cm

Perpendicular [tex]=x[/tex] cm

One of the angle [tex]=33^0[/tex]

So,

Using the Trigonometric angles,

[tex]Sin33^0=\frac{Perpendicular}{Hypotenuse}[/tex]

So,

[tex]Sin33^0=\frac{x}{18}[/tex]

[tex]x=18*Sin\ 33^0[/tex]

So,

[tex]x=9.8[/tex]

The missing side is [tex]9.8[/tex] .

Hence, we can say that the missing side of Right triangle will be [tex]9.8[/tex].

Olivia works at a company that creates mobile phones. She wanted to estimate the mean amount of time their new phone's battery lasts with regular use after a full charge. She took a random sample of 6 of these phones and randomly assigned each of them to a volunteer. She instructed them to fully charge the phones and use them as they regularly would until the battery died (without recharging the phone). Here are the data they reported:

Step-by-step explanation:

Kahn

The required possible 90% confidence interval for the mean battery life is (10.95, 19.05) hours.

What is Statistic?

Statistic is the study of mathematics that deals with relations between comprehensive data.

Here,
Assuming that the sample means and sample standard deviation were calculated from the data, a possible 90% confidence interval for the population means battery life can be calculated using the t-distribution.

For example, if the sample mean is 15 hours and the sample standard deviation is 3 hours, with a sample size of 6 and a 90% confidence level, the t-interval would be:

t-interval = sample mean ± t*(sample standard deviation / √(sample size))

where t is the t-value with (sample size - 1) degrees of freedom and a 90% confidence level.

Using a t-table, the t-value for 5 degrees of freedom and a 90% confidence level is approximately 2.571. Plugging in the values, we get:

t-interval = 15 ± 2.571*(3 / √(6))

t-interval ≈ (10.95, 19.05)

Therefore, a possible 90% confidence interval for the mean battery life is (10.95, 19.05) hours.
