Answers

Answer 1

The angle 'b' measure 120 degrees from the diagram.

Solving angles in circle geometry

The given diagram is a circle geometry. Given the following parameters

x= 44° and;

a = 32°

In order to determine the measure of angles 'b'. we will use the expression below;

x = 1/2(b + a)

44 = 1/2 (b- 32)
88 = b - 32

b = 88 + 32

b = 120 degrees

Hence the measure of the angle 'b' from the diagram is 120 degrees.

The amount of time Jill trained for a marathon this month is 125% of the amount of time she trained last month. If Jill trained for 80 hours last month, how many hours did she train this month?

I need to do this in the Percent Porportion way. I know how to do it but I do not know the awnser. :)​

Answers

Answer:

The amount of time Jill trained this month is 125% of the amount of time she trained last month, which was 80 hours. To find the number of hours she trained this month, we can multiply 80 hours by 125%:

80 hours * 125% = 80 hours * 1.25 = 100 hours

So Jill trained for 100 hours this month.

Answer:

100hours

100 hours / 80 hours * 100% = 125%

Step-by-step explanation:

The amount of time Jill trained this month is 125% of the amount of time she trained last month, which was 80 hours. So, she trained for 125% of 80 hours = 100 hours.

To find this answer as a percentage, we can calculate what percentage of 80 hours 100 hours is:

100 hours / 80 hours * 100% = 125%

So Jill trained for 125% of the amount of time she trained last month.

Of the three important sources of resistance, which ones remain relatively constant?1.Blood viscosity 2.Blood vessel length

Answers

The blood viscosity and vessel length remain relatively constant, the regulation of vessel radius becomes the primary mechanism for controlling resistance in the body.

Blood viscosity refers to the thickness or stickiness of blood, which is determined by the number and size of red blood cells, as well as the concentration of proteins and other substances in the plasma.

Blood viscosity affects resistance because the thicker the blood, the more difficult it is for it to flow through the blood vessels.

Blood vessel length refers to the distance that blood has to travel through the vessels, which affects resistance because the longer the vessel, the more difficult it is for blood to flow through it.

However, vessel length remains relatively constant in the body because it is determined by the body's anatomy and does not change significantly over time. Therefore, the only time when vessel length can change is during a surgical procedure or injury that alters the anatomy of blood vessels.

Mathematically, the resistance to blood flow (R) can be calculated using the formula R = (8 x viscosity x length) / (π x radius⁴).

This formula shows that blood viscosity and vessel length are directly proportional to resistance, while vessel radius is inversely proportional.

Therefore, any increase in blood viscosity or vessel length will increase resistance, while any decrease in vessel radius will increase resistance.

The volume of the cone is 471 cubic yards and the radius is 5. What is the height of the cone?
ues 13.4 for π

Answers

Answer:

Step-by-step explanation:

The formula for the volume of a cone is given by:

V = (1/3)πr^2h

where V is the volume of the cone, r is the radius of the base, h is the height of the cone, and π is the mathematical constant pi (approximately equal to 3.14159).

Substituting the given values, we get:

471 = (1/3) x 13.4 x 5^2 x h

Multiplying both sides by 3 and dividing by 13.4 x 25, we get:

h = 471 x 3 / (13.4 x 25)

h ≈ 6.98 yards (rounded to two decimal places)

Therefore, the height of the cone is approximately 6.98 yards.

what day is 75 days from now?

Answers

The date that is 75 days from now, if today is February 22, 2023, is May 8, 2023.

To find the date that is 75 days from now, we can start with the current date and add 75 days to it. This can be done by adding the number of days to the day of the month, and if necessary, advancing to the next month or year.

For example, if today is February 22, 2023, we can count forward 75 days on a calendar to find the date that is 75 days from now. This would take us to May 8, 2023.

Here is the mathematical calculation:

Current date + 75 days = (February 22, 2023) + 75 days

= February 22, 2023 + 75 days

= (February 22, 2023 + 31 days) + (44 days)

= March 25, 2023 + 44 days

= (March 25, 2023 + 30 days) + (14 days)

= April 24, 2023 + 14 days

= (April 24, 2023 + 14 days)

= May 8, 2023

Therefore, the date that is 75 days from now, if today is February 22, 2023, is May 8, 2023.

two trains, train a and train b weigh a total of 537 tons. train a is heavier than train b. the difference if their weights is 421 tons. what is the weight of each train?

Answers

Answer:

Let the weight of Train A be x tons. Then the weight of Train B is 537 - x tons. We know that the difference between their weights is 421 tons, so we can set up an equation to solve for x:

x - (537 - x) = 421

Expanding the right side:

x - 537 + x = 421

Combining like terms:

2x = 958

Dividing both sides by 2:

x = 479

So Train A weighs 479 tons and Train B weighs 537 - 479 = 58 tons.

Ennis wants to make a border for a triangular-shaped vegetable garden. He has 4 pieces of wood that measure 8 inches, 10 inches, 12 inches, and 18 inches. How many different triangular borders can ennis make?.

Answers

After considering all the combinations of three pieces of wood, we can conclude that Ennis can make 2 different triangular borders for his vegetable garden.

A triangle is a shape with three sides, and each side can be considered as a side length. In order to form a triangle, the sum of the lengths of the two shorter sides must be greater than the length of the longest side.

To find the number of different triangular borders that Ennis can make, we need to consider all the combinations of three pieces of wood as the sides of the triangle. There are four pieces of wood, so the number of combinations of three pieces is 4 choose 3, which is 4.

Now, we need to determine if each combination of three pieces of wood forms a triangle. If the sum of the lengths of the two shorter sides is greater than the length of the longest side, it forms a triangle. If not, it does not form a triangle.

If Ennis uses the 8-inch and 10-inch pieces as two sides, he can use the 12-inch or 18-inch piece as the third side, and it forms a triangle.

If he uses the 8-inch and 12-inch pieces as two sides, he can only use the 10-inch piece as the third side, and it forms a triangle. If he uses the 8-inch and 18-inch pieces as two sides, it does not form a triangle.

order to avoid crashing into the trees? Round to the nearest hundredths.
Select an answer
Question Help: Message instructor

Answers

To find the angle of elevation, we need to determine the height of the plane relative to the trees, and then use the tangent function to find the angle. Let's call the height of the plane "h".

We can set up a right triangle with the height of the plane, the distance from the runway to the trees, and the height of the trees.

We have:

h / (150 + 75) = 100 / h

Solving for h, we find that:

h = 125

So the height of the plane relative to the trees is 125 feet.

Now we can use the tangent function to find the angle:

tan(angle) = 100 / 125

angle = tan^-1(100 / 125)

angle = approximately 53.13 degrees

Rounding to the nearest hundredths, the angle of elevation that the pilot must take to avoid crashing into the trees is 53.13 degrees.

An income tax refers to the tax imposed on individuals or entities in respect of the income earned by them. It is computed as the product of a tax rate times the taxable income. They may vary by type or characteristics of the taxpayer and the type of income

To calculate the worker's monthly tax, we need to determine the amount of salary that falls into each tax bracket and then calculate the tax owed for each bracket:

For a monthly salary of K30,000, the first K9,000 is tax-free, leaving K21,000 to be taxed. Of this K21,000, the first K10,000 is taxed at 15%, which gives a tax of K1,500. The next K12,000 is taxed at 25%, which gives a tax of K3,000.Finally, the remaining K-1,000 is taxed at 35%, which gives a tax of K350.

The worker's monthly tax is then computed as:

Either sides of an equation is called as left hand side and right hand side.

Given that,

When an integer is subtracted from 6 times the next consecutive integer, the difference is 41.

Let the integer be x.

Then the next consecutive integer will be x + 1

6 times the next consecutive integer means 6 (x + 1).

an integer is subtracted from this means 6 (x + 1) - x.

The difference of this is 41.

6 (x + 1) - x = 41

By distributive property,

6x + 6 - x = 41

5x + 6 = 41

5x = 41 - 6

5x = 35

x = 7

Hence the value of the integer is 7 and the value of next consecutive integer is 8.
