Find the value of x in each triangle

Answers

Answer 1

Both x’s are 77.5 because a triangle must add up to 180. If you know 25 you can subtract from 180 and divide by 2.

Answer 2

Answer:

Step-by-step explanation:

The sum of a triangle’s angles is always 180 degrees so

x+x+25=180

2x+25=180

2x=155

x=77.5 degrees

Pls help find the surface area

Answers

Answer:

114

Step-by-step explanation:

17 + 8 = 25

25 ÷ 2 is for one triangle.

25 ÷ 2 = 12.5

12.5 x 4 = 50

(4, because there are 4 triangles)

Then, 8 x 8 is for the middle square, which is 64

64 + 50 = 114

So, The surface area is 114

Find the length of a rectangular prism having a volume of 60 cubic meters, width of 2 1/2 meters, and height of 3 1/3

Answers

Answer:

7 1/5 m

Step-by-step explanation:

Find the length of a rectangular prism having a volume of 60 cubic meters, width of 2 1/2 meters, and height of 3 1/3

Volume of a rectangular prism = Length × Width × Height

Length = Volume/ Width × Height

Length = 60 m³/2 1/2 m × 3 1/3 m

Length = 60 m³/8 1/3 m²

Length = 60 m³÷ 8 1/3 m²

= 60 m³ ÷ 25/3 m²

=( 60 × 3/25 )m

= 180/25 m

Length = 7 1/5 m

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,340 ft Determine the flag's width and length if the length is 390 ft greater than the width.

Answers

Answer:

Step-by-step explanation:

L=W+390, W=L-390

P=2(W+L), P=2340

2(L-390+L)=2340

2L-390=1170

2L=1560

L=780ft

Given the slope of the line containing the points (7 , b) and (-2 , 5) is 4/9, find the value of b

Answers

Answer: b=9

Step-by-step explanation: To find the slope we use: y2-y1/x2-x1

Which would then be: 5-b/-2-7= 5-b/-9

Then we have to find a number for b that would give us -4 as the numerator. That number would be 9

This would give us 4/9 which is the slope we already had.

A highway sign shows a speed limit of 60 miles per hour. Which of the following car speed measurements represent the same level of accuracy compared to the speed limit sign? Check all that apply. A. 64 mph B. 56 mph O C. 48 mph O D. 68 mph

Answers

Answer:

B and C

Step-by-step explanation:

IT is found that B. 56 mph and C. 48 mph car speed measurements represent the same level of accuracy compared to the speed limit sign.

What is speed?

Speed can be calculated as the ratio of distance traveled to the time taken

We can see that As the speed limit on the highway is 60 miles per hour and the speeds mentioned above are below the speed limit.

The legal top speed at which a vehicle may travel on a specific section of road is determined by speed limits for road traffic, since they are utilized in the most of countries.

On a traffic sign, it is known that the maximum allowed speed is typically displayed and expressed in kilometers per hour (km/h) or miles per hour (mph).

Read the passage.A Flag with 50 StarsThe first American flag to have red and white stripes and white stars on a blue field was flown in 1776, shortly after the United States declared its independence from Great Britain. Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag. There is no evidence that this legend is true, and no one knows for certain who made the first flag, which had 13 stars and 13 stripes. However, we know for a fact that the first flag to have 50 starsthe one we have todaywas designed by a high school student. In 1958, Bob Heft was a 17-year-old student at Lancaster High School in Ohio. At that time, the United States had only 48 states but was on the verge of accepting two more: Alaska and Hawaii. The U.S. flag at the time had six neat rows of eight stars each. What would be the best way to add two more stars while keeping the arrangement neat and orderly? This was the question that Bobs history teacher posed to the class. The teacher gave the students an assignment: design a flag with 50 stars. Bob spent hours in the attic of his house, cutting up a 48-star flag and rearranging the stars until they fit just right. He was pleased with his solution to the problem, but his teacher found it less than perfect and gave him a B minus. Outraged, Bob told his teacher that he was going to send his design to his member of Congress, Walter Moeller. His teacher replied that if Bobs design was accepted as the new flag, he would be more than happy to change the grade to an A. A year later, Bob had graduated and was working as a draftsman when he received a call at work. He never would have imagined a call from President Eisenhowerbut that's who it was! Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag. Bob Heft was invited to Washington, D.C., for a ceremony during which his design was officially adopted as the new flag of the United States.Read the excerpt from A Flag with 50 Stars. Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag.How do these sentences contribute to the text?They imply that the people of Alaska and Hawaii prefer Bob's design over other options.They show it takes several years for the U.S. government to approve a new flag design. They develop the idea that Bob's design is exceptional, despite what his teacher thought.They develop the idea that, without Congressman Moeller, there would not be a new U.S flag. 1.
