A group of friends were working on a student film that had a budget of $900. They used 33% of their budget on equipment. How much money did they spend on equipment?​

Answers

They used 33/100 of their money on equipment which means if they have a budget of 900 dollars they used...

900*33/100=9*33=297 dollars on equipment.

The amount used on equipment is $297.

What is a percentage?

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying it by 100.

The percentage change is also calculated using the same method.

In percentage change, we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Budget = $900

Percentage of the budget used.

= 33%

Now,

The amount of budget used.

= 33% of 900

= 33/100 x 900

= $297

Thus,

The amount used on equipment is $297.

Answer:

x = 6

Step-by-step explanation:

The area of a triangle is equal to the base times the height divided by two. In this case, the base is 6 (or x, it doesn't really matter) and the height is x (or 6, it doesn't matter). That means that the area of this triangle is equal to 6 * x divided by 2, which is also equal to 18. we can say that 6x/2 = 18, meaning that 6x = 36, so x = 6.

Taylor is decorating for a party. She cuts 5 equal-length streamers from a strip of yellow paper that is 9 feet long. How long is each streamer in fraction form?

Answers

Answer: 1 4/5 feet

Step-by-step explanation:

Length of the strip of yellow paper = 9 feet.

Number of streamers that were cut = 5

Length of each streamer will then be:

= Length of the strip of yellow paper = 9 feet / Number of streamers that were cut

= 9 feet / 5

= 1 4/5 feet

find the area of the shape using Pythagoras Theorem please​

Answers

Answer:

122.09 (the answer may change depending on how many decimals you need if you need more or less just follow the steps using however many decimals)

Step-by-step explanation:

to get the other triangle side do 18-11= 7

then use the Pythagoras theorem to solve for the other side so 7^2+b^2=11^2

49+b^2= 121

121-49= b^2

72=b^2

b= 8.48(simplified)

then use that side to get the area of the rectangle:

8.42×11=92.62

then get area of the triangle:

1/2(8.42×7)=29.47

add the 2 areas to get total area:

92.62+29.47=122.09

Answer: 250 im not sure if its correct though

Step-by-step explanation: 8% = 8/100  

8 /100  × x = 20

Multiplying both sides by 100 and dividing both sides by 8,

we have x = 20 ×  100 /8

x = 250

(cosec a + 1)*(1 - sin a)= cos a* cot a

Answers

Answer:

See proof below

Step-by-step explanation:

Given the equation, we are to prove that it is true

(cosec a + 1)*(1 - sin a)= cos a* cot a

From LHS

(cosec a + 1)*(1 - sin a)=

Expand

cosec a - cosecasina + 1 - sina

Since cosec a = 1/sina

1/sina - (1/sina)sina + 1 - sina

1/sina - 1 + 1 - sina

1/sin a - sina

Find the LCM

1-(sin^2a)/sina

cos^2a/sina

cosa * cosa/sina

cos a * cot a (which gives the RHS)

In one to two sentences, explain how the author uses a counterclaim to help support his or her position regarding school uniforms. Be sure to use proper grammar, spelling, and mechanics."School Uniforms"Requiring uniforms in public high schools has been debated for many years. There are certainly many positive reasons for having students wear them. If students were uniformly dressed, there would be less distractions about clothing, adding more focus on academics. Another reason to add uniforms is that there would no longer be conflict over how young people dress. There would be no singling out of poorer students who cannot wear designer labels, and young people wouldn't have to worry so much about fitting in because of how they dress. Opponents, however, say requiring school uniforms suppresses a young person's need for individuality. This simply isn't the case, though, as students can use hairstyle, jewelry, and so on to show their individuality. Requiring school uniforms would erase a number of conflicts and problems facing high school students today. Vaughn threw the shot put 9 yards at a track meet.
