A student measured the length of a certain bar as 20 cm, which exceeded the actual length by 10% the actual length of the bar was​

Answers

Answer 1

Answer:

18cm

Step-by-step explanation:

20/10 = 2cm

So since 2x10 is 20 and it exceeded only 10%, we only subtract 2 from 20 which you leave you with 18cm.

during the work week mrs. Jamison drive 75 miles each way to work if she works 21 days each month how far does she drive for the work during the month​

Answers

Answer:

See below:

Step-by-step explanation:

So, the question asks how far she drives in a month, this probably includes going to work and coming back. Therefore, each day takes 2 times 75 which is 150!

Now, we know she goes 150 miles each day going to work and coming back. We can now multiply that by 21 to get out answer.

We can split 21 into 10 * 2 + 1 for our convenience.

150 times 10 is 1500 and that times two is 3000 added by 150 is 3150.

Then we get out answer; 3150 miles!

Answers

Answer:

250 $3 tickets and 100 $2 tickets were sold.

Step-by-step explanation:

A family bought a total of 13 tickets to a magic show, some adult and some child. The family paid a total of $85 Adult tickets are $15 each and tickets are $5 each. Let X represent adult tickets. Let y represent child tickets Write an equation to model the total amount of money that they spent.The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?

Let x = number of $3 tickets

Let y = number of $2 tickets

Total = quantity × value

quantityvaluetotal$3 ticketsx33x$2 ticketsy22ytogether350950

Step 3: Add down each column to get the equations

x + y = 350                    (equation 1)

3x + 2y = 950                (equation 2)

Use Substitution Method

Isolate variable x in equation 1

x = 350 – y                     (equation 3)

Substitute equation 3 into equation 2

3(350 – y) + 2y = 950

1050 – 3y + 2y = 950

3y – 2y = 1050 – 950

y = 100

Substitute y = 100 into equation 1

x + 100 = 350

x = 250

Answer: 250 $3 tickets and 100 $2 tickets were sold.

Step by step explanation only!​

Answers

Answer:

See Below.

Step-by-step explanation:

We want to verify the equation:

[tex]\displaystyle \frac{\tan\theta}{ 1- \cot \theta} + \frac{\cot\theta}{1 - \tan\theta} = \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}}[/tex]

Recall that tanθ = sinθ / cosθ. Likewise, cotθ = cosθ / sinθ. Then by substitution:

[tex]\displaystyle \begin{aligned} \frac{\tan\theta}{ 1- \cot \theta} + \frac{\cot\theta}{1 - \tan\theta} & = \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}} \\ \\ & \stackrel{\checkmark}{=} \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}} \end{aligned}[/tex]

Hence verified.

Given :

tan∅/1-cot∅ + cot∅/1-tan∅ = sin∅/cos∅ ÷ (1- cos∅/sin∅ ) + cos∅/sin∅ ÷ (1 - sin∅/cos∅)

To Do :-

To prove LHS = RHS

Proof :-

We know that ,

sin∅/cos∅ = tan∅cos∅/sin∅ = cot∅

On using above two in LHS ,

LHS = tan∅/1-cot∅ + cot∅/1-tan∅LHS = tan∅/1-cot∅ + cot∅/1-tan∅ = sin∅/cos∅ ÷ (1- cos∅/sin∅ ) + cos∅/sin∅ ÷ (1 - sin∅/cos∅) LHS = RHS

Hence proved !

do you guys really find this site helpfull what is the value of x? The passage supports the idea thatNelson Mandela Nelson Mandela is known throughout the world for his fight against apartheid, the separation of blacks and whites. In 1944, while in his 20s, Mandela joined the African National Congress (ANC). The ANC was a political organization that fought against the racist policies of the South African government. Mandela led a peaceful resistance against the South African government for 20 years. He implemented strategies such as boycotts, strikes, civil disobedience, and non-cooperation. As a leader of the ANC, Mandela fought for blacks to have the right to vote and to travel without the use of documents called dompas. Mandela also fought for workers' rights and for free education for children of all colors. In 1960, the South African government banned the ANC. The organization went underground. Mandela decided that peaceful resistance was ineffective in the fight to end apartheid. He began supporting militant or aggressive actions against the South African government. In 1962, Mandela was arrested for leading a national workers' strike. The South African government sentenced him to five years in prison. While in prison, Mandela was charged with sabotage and was sentenced to life in prison. The South African government had hoped that locking Mandela behind bars would discourage his followers. However, Mandela became a symbol for the anti-apartheid movement. In 1985, President P. W. Botha tried to make a deal with Mandela. He offered to set Mandela free if Mandela agreed to call off the armed fight against apartheid. Mandela immediately declined this offer. In 1989, Frederik Willem de Klerk became the president of South Africa. He released Mandela from prison in 1990 and lifted the ban on the ANC. After spending 27 years in prison, Mandela continued to pressure the South African government to end apartheid. He called on foreign leaders to join him in the fight for blacks to have the same rights as whites. Mandela also continued to support the ANC's use of weapons against the South African government. Mandela worked with President F. W. de Klerk to establish the first multiracial elections in South Africa. In 1993, both men received the Nobel Peace Prize for their efforts to end apartheid. The government of South Africa held the first democratic elections in 1994. Nelson Mandela won the election and became the first black president of South Africa. A. The African National Congress was a disorganized group. B. Nelson Mandela failed at his attempts to end apartheid. C. President F. W. de Klerk believed that apartheid was immoral. D. The South African government was in favor of democratic elections. What's the area of this?
