The measures of the angles of a quadrilateral in degrees are 70, 95, and 136. Determine the measure of the missing angle.

Answers

Answer:

let missing Angle be x

x+70+95+136=360 sum of interior angle of quadrilateral is 360

x+301=360

x=360-301=59°

therefore the measure of the missing angle is 59°

Robert takes out a loan for $7200 at a 4.3% rate for 2 years. What is the total paid amount at the end of the loan?

Answers

Answer:

$7819.20

Step-by-step explanation:

total paid amount at the end of the loan= loan taken + interest on the loan

loan taken = $7200

interest on the loan can be determined using this formula

Interest = principal x intrest rate x time

7200 x 0.043 x 2 = $619.20

total paid amount at the end of the loan= $7200 + $619.20 = $7819.20

Brad read that you should drink at least 2 quarts of water a day. Yesterday he drank 3 cups in the morning, 1 quart in the afternoon, and 1 pint in the evening. Did Brad drink at least 2 quarts of water? Explain.

Answers

Answer:

yes he drank 2.25 quarts

Step-by-step explanation:

convert the cups to quarts

1 cup = 0.25 quarts

3 cups x 0.25 = 0.75 quarts

convert the pints to quarts

1 pint = 0.5 quarts

add all the amount of water drank together

0.75 quarts + 1 quart + 0.5 quarts = 2.25 quarts

Answers

Answer:

y=7.3

Step-by-step explanation:

with the two points, you could find the point-slope equation...

y−7.3=0⋅(x+4)

this is y=7.3

there is no slope-intercept equation for this because both of the points are on the same horizontal line. Equations that are written in slope-intercept form are never horizontal or vertical.

4x + 8 - 9x = -17 what is x\

and the x has to be the same for each

Answers

Answer:

x = 5

Step-by-step explanation:

4x + 8 - 9x = -17

combine like terms:

-5x = -25

divide both sides of the equation by -5:

x = 5

Answer:

x=5

Step-by-step explanation:

4x-9x+8=-17

-5x+8=-17

subtract 8 from both sides and you get:

-5x=25

divide 5 from both sides, and you get x=5! :)

to insure goods to send them overseas it costs the exporter 5/2% of the value of the goods. if the goods are valued at 16.400$, what will be the insurance cost?

Answers

Answer:

The insurance costs to send goods valued at $16,400 is $410

Step-by-step explanation:

The amount it costs an exporter to insure goods to send overseas = (5/2)% of the value of the goods

Therefore;

The insurance costs, 'C' to send goods valued at $16,400 is given as follows;

C = $16,400 × (5/2)/100 = $410

The insurance costs to send goods valued at $16,400 = $410

Read the excerpt from The Mother of America:George Washington is frequently considered the "Father of America." Likewise, his wife, Martha Washington, could also be considered the "Mother of America," as demonstrated by her roles as the general's wife and the first lady.During the American Revolution, Martha Washington earned the title of "Mother of America" for her caring nature as the general's wife. She was also very brave. Despite the danger of kidnapping, Martha refused to abandon her home, Mount Vernon, in Virginia. When Martha did leave the plantation for periods of time, she traveled to the military camps where Washington was staying. First, Martha had to be vaccinated so that she would not suffer from smallpox. Once she was inoculated, Martha made the risky trip to camp. British and American soldiers roamed the countryside, and capture was a real possibility. Nevertheless, Martha arrived at each winter camp. She acted as confidant and secretary to George Washington, who believed that her presence was crucial. She encouraged the soldiers, helped their wives, and comforted those who were wounded. One of her key roles was also to entertain important visitors to the camp. Occasionally, Martha Washington even represented George at events he could not attend. Martha used her position to contribute to fundraising efforts for military supplies in 1780 and knit socks for the soldiers herself. Overall, her care and attention to others' needs made her the "Mother of America" during the American Revolution.Which of the following passages best summarizes the point and first reason of The Mother of America?a. Martha Washington could be considered the "Mother of America" due to her care and attention to others' needs as the general's wife. She was inoculated for smallpox. She stayed at Mount Vernon even though there was the possibility that she would be kidnapped. She hosted and entertained many important visitors on behalf of George Washington. She was the "Mother of America."b. Martha Washington could be considered the "Mother of America" for her kindness towards others in her role as the general's wife. Despite great danger, she journeyed to the military camps to spend time with George Washington and his soldiers. She acted as Washington's secretary, confidant, and representative. She also demonstrated care for the soldiers and their wives by encouraging them, knitting socks, and contributing to fundraising efforts.c. The caring nature Martha showed as the wife of Washington proved that she should be called the "Mother of America." She journeyed to the military camps to spend time with George Washington and his soldiers. She acted as Washington's secretary, confidant, and representative. She also demonstrated care for the soldiers and their wives by encouraging them, knitting socks, and contributing to fundraising efforts.Selected:d. The caring nature Martha showed as the wife of Washington proved that she should be called the "Mother of America." Martha arrived at each winter camp and demonstrated her caring nature as the general's wife. She acted as confidant and secretary for George Washington. She encouraged the soldiers, helped their wives, and comforted those who were wounded.
