ZA and ZB are complementary angles. If mZA = (2x + 10)° and m
ZB = (3x + 15)', then find the measure of ZB.

Answers

Answer:

∠ZB = 54°

Step-by-step explanation:

Given:

Pair of complementary angles

∠ZA = (2x + 10)° and m

∠ZB = (3x + 15)

Find:

Measure of ∠ZB

Computation:

complementary angles

a + b = 90°

∠ZA + ∠ZB = 90°

(2x + 10) + (3x + 15) = 90

5x + 25 = 90

x = 13

So,

∠ZB = (3x + 15)

∠ZB = 13(3) + 15

∠ZB = 54°

The volume of a cylinder is 65 cubic centimeters. Which equation can be used to find h, the height of the cylinder?
A. h = 65/b, where B is the base area of the cylinder.
B. h = 65 - B, where B is the base area of the cylinder.
C. h = 65B, where B is the base area of the cylinder.
D. h = B/65, where B is the base area of the cylinder.

Answers

Answer:

Im so sorry for do this but can you help me click my profile pic the click the last question PLZZZZZZZ will give 50 brain

Step-by-step explanation:

The equation that can be used to find h, the height of the cylinder, is h = B/65. The correct option is D.

How to calculate the height?

The formula for the volume of a cylinder is:

V = Bh

Where V is the volume, B is the base area, and h is the height of the cylinder. We are given that the volume of the cylinder is 65 cubic centimeters, so we can write:

65 = Bh

To solve for h, we can divide both sides of the equation by B:

h = 65/B

Therefore, the equation that can be used to find h, the height of the cylinder, is:

D. h = B/65, where B is the base area of the cylinder.

Ben and Landon took turns driving on the recent 820 mile road trip Ben averaged 60 mph while Landon average 56 mph if the trip took them 14 hours how many hours did Landon Drive

Answers

Answer:

9 hours

Step-by-step explanation:

Let :

Landon hours = x

Ben hours = y

x + y = 14 - - (1)

60x + 56y = 820 - - - (2)

From (1)

y = 14 - x

60x + 56(14 - x) = 820

60x + 784 - 56x = 820

4x = 820 - 784

4x = 36

x = 36/4

x = 9

Landon drove for 9 hours

Mr. Ford Invested $12,450 in a bank at 7.25% per annum simple interest for 6 years. calculate the interest he was paid

Answers

Answer:

If my calculations are correct, $5415.75 of interest was paid throughout 6 years.

Step-by-step explanation:

7.25% of 12,450 is 902.625.

If the interest being paid was the 7.25% of 12,450 throughout the 6 years then the answer is 902.625 x 6 ( the amount of years ) = $5415.75.

In other cases such as 7.25% of the new number of invested money after the loss of 902.625 then this answer is wrong, but I solved as I understood.

Hope this helps.

Which expression models the phrase "Wally mowed two more lawns than he mowed last week"? n + 2 n minus 2 2 minus n 2 n

Answers

Given:

The phrase is "Wally mowed two more lawns than he mowed last week".

To find:

The expression that models the given phrase.

Solution:

Let the number of lawns mowed by Wally last week be n.

We know that, we use plus sign "+" for "more".

If Wally mowed two more lawns than he mowed last week, then the lawns mowed by the Wally this week is the sum of n and 2.

Lawns mowed this week = [tex]n+2[/tex]

The required expression for the phrase "Wally mowed two more lawns than he mowed last week" is n+2.

Therefore, the correct option is A.

b)Find the perimeter of the image of WXYZ after dilation of 1/2 centered at origin and compare it to perimeter of WXYZ

Answer:

Step-by-step explanation:

1. Use The Coordinates To Find The Distances Of The Four Sides

2. The Formula For Perimeter Or A Quad =

AB + BC + CD + AD

Basically Add The Distances Of The Four Sides

So: WX + XY + YZ + WZ

[tex] \sqrt{34} + 5 + \sqrt{61} + 2 \sqrt{5} [/tex]

= 23,11333753

We can write the parameter as -

P = 23.13P = 11.55

What is a quadrilateral?

In geometry a quadrilateral is a four-sided polygon, having four edges and four corners.

Given is that WXYZ has vertices W(6, 2), X(3, 7), Y(-1, 4), and Z(4, -2).

The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 - dimensional plane, the distance between points (x₁, y₁) and (x₂, y₂) is given by the Pythagorean theorem -

{d} = √{(x₂ - x₁)² + (y₂ - y₁)²}

{ a } -

WX = 5.83

XY = 5

YZ = 7.8

ZW = 4.5

So the perimeter would be -

P = WX + XY + YZ + ZW

P = 5.83 + 5 + 7.8 + 4.5

P = 23.13

{b} - After the dilation, the sides will become -

WX' = 5.83/2 = 2.9

XY' = 5/2 = 2.5

YZ' = 7.8/2 = 3.9

ZW' = 4.5/2 = 2.25

The perimeter will be -

P = WX' + XY' + YZ' + ZW'

P = 2.9 + 2.5 + 3.9 + 2.25

P = 11.55

Therefore, we can write the parameter as -

P = 23.13P = 11.55

Amelia Earhart was born in 1897 in a small Kansas town. That was six years before the Wright brothers took their famous first airplane flight in Kitty Hawk, North Carolina. Over the next two decades, aviation developed rapidly, but the pilots at the controls were mainly men. Amelia Earhart broke through that barrier to become a famous aviator, and she paved the way for women who followed. Amelia Takes OffAmelia took her first flying lesson in 1921. At the end of the year, she received her pilots license. She took odd jobs and received financial help from her mother to buy her own airplane. With a plane of her own, Amelia quickly began making a name for herself in the aviation world. In October 1922, she broke a world record for female pilots by flying her plane to 14,000 feet in altitude. In 1923, she received her International Pilots Licensejust the sixteenth woman in the world to do so. Unfortunately, Amelia had to sell her plane to give her mother money, and for a while, her love of aviation became more of a hobby.But this all changed in 1928 when Amelia was contacted by publisher George Putnam, who she later married. He invited her to be a passenger on a cross-Atlantic flight. Amelia would have preferred to be the pilot, not the passenger, but at the time, flying a plane over an ocean was considered too dangerous for women.The flight was successful, and Amelia became world-famous as the first woman to fly across the Atlantic. However, Amelia was not satisfied. She did not get to operate the controls during the flight and thought of herself as being no more important to the flights success than a sack of potatoes. She was determined to fly on her own.Amelia Reaches StardomIn 1929, Amelia became involved with an organization called the Ninety-Nines, a group that promoted female pilots in the aviation industry. She was the groups first president. In May of 1932, Amelia crossed the Atlantic again, but this time she was at the controls. She made the trip from Canada to Ireland in 15 hours. She received many medals and awards for her achievement.Amelia hoped her success would open doors for women in aviation and in other fields, so she continued flying and setting records. She became the first person to fly across both the Atlantic and Pacific oceans when she flew from Hawaii to California.An Extraordinary MissionEven after proving she was a world-class aviator, Amelia still wanted more. In 1937, she set off on an amazing trip: flying around the world. Amelia started in California but faced trouble along the way. She became ill, her plane needed repairs, and bad weather forced a change in the flight route. She made it to one of her planned stops near Australia, but she never made it to her next destination. People all over the world were following the news of Amelias tripand now she was missing! President Franklin D. Roosevelt conducted a $4 million rescue mission, but Amelia was never found.Amelia hoped that her actions would inspire other women to follow their dreams. One of her lifelong missions was for the world to recognize that women could have the same careers as men. Even though she died at a young age, just 40 years old, Amelia was an inspiration to many.Amelia Earhart is sitting in her plane with her aviation hat and goggles on.Which elements from Amelia Earhart: Pioneer show that it is not a tall tale?
