Sara has rs. 836 with her. she gives 9/11 of this to her sister. out of the remaining money, she gives rs. 38 to her brother. she now has a fraction of the original amount is left with her?

Answers

Answer 1

The original amount Sara has left is 172/209

The calculation can be done as follows

Let y represent the amount left

9/11 × 836

= 7524/11

= 110

Y  can be calculated as follows

Y + 38 +110= 836

148 + Y= 836

Y= 836 - 148

Y= 688

Therefore the fraction is

688/836

= 172/209

Hence the fraction of the original amount left is 172/209

Write the equation of the line that passes through the points (-9,-9)(−9,−9) and (6,-7)(6,−7). Put your answer in fully simplified form, unless it is a vertical or horizontal line.

Answers

2x-15y = 117 is the simplified form of the equation.

Equation : In a mathematical sentence, if two expressions are present in left and right side of an equal sign, then the mathematical sentence is called an equation.

If, a, b, c be integers and x is x-intercept & y is y-intercept, then ax+by=c is called equation of line.

Given that, the equation of the line that passes through the points (-9,-9)(−9,−9) and (6,-7)(6,−7).

Now, (-9,-9) & (6, -7) have a line through them with slope = (-9+7)/(-9-6) = 2/15

Therefore, (y+7) = 2/15×(x-6)

⇒ y+7 = 2x/15 - 4/5

⇒ y = 2x/15 - 4/5 - 7

⇒ y = 2x/15 -39/5

This is the equation in slope intercept form.

Multiplying the equation with 15, we get,

⇒ 15y = 2x-117

⇒ 2x-15y = 117 , which is the simplified form of the equation.

What is angle of elevation and depression?

The angle formed by the line of sight and the horizontal plane for an object above the horizontal.

The angle of depression is the angle between the horizontal line and the observation of the object from the horizontal line.

Given:

we have two angles one of which is angle of elevation and another angle depression.

Using trigonometric ratio,

tan ∅ = P / B

tan 32° = h / 425

0.624= h /425

h= 265.569 ft

again,

tan 29° = h(bottom of the tower) / 425

h(bottom of the tower) = 425 × tan 29°

h(bottom of the tower)  = 235.581 ft

Thus, Height of tower = h(top of the tower) + h(bottom of the tower)

Height of tower = 265.569  + 235.581

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

The floor measures 4 1/2 ft by 3 3/4 ft.

Hence:

Area of floor = 4 1/2 ft * 3 3/4 ft = 9/2 ft * 15/4 ft = 16.875 ft²

Each tile measures 1 square foot each, hence:

number of tiles needed = 16.875 ft² / 1 ft² per tile = 16.875 tiles ≅ 17 tiles

What is a median?The median is the value that separates the upper and lower halves of a data sample, population, or probability distribution in statistics and probability theory. It is sometimes referred to as "the middle" value in a data set. The main difference between the median and the mean in summarizing data is that the median is not skewed by a tiny fraction of exceptionally big or small values, and thus provides a better depiction of a "typical" value. Because income distribution can be distorted, median income may be a better approach to illustrate what a "normal" income is.

A ticket costs £656
Last year it cost £640
What percentage increase is this ?

Answers

Answer:

2.5%

Step-by-step explanation:

656 / 640 = 1.025

1.025 into percent is 102.5%

102.5% - 100% = 2.5

640 + 2.5% of 640 = 656

BOOM

The required value of increase in price is 2.5%.

What is percentage?

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

Given that,

The cost of ticket at present is £656.

Its cost last year was £640.

Then, the difference between the costs is given as,

656 - 640 = £16

Now, the increase in percentage can be found by taking the ratio of the difference to the last year price and multiplying it by 100 as below,

Percentage increase = 16/640 × 100%

                                   = 2.5%

Hence, the percentage increase in price is 2.5%.

If x represents the number of pounds of peaches bought and y represents the total cost of the peaches, which best describes the values of x and y?The values of both x and y can be any real number.The values of both x and y will be real numbers greater than or equal to 0.The value of x and y will always be zeroThe value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0. Mark this and return Suppose that 75% of the students enrolled in programs at the School of Business at USC are undergraduate students and the rest are graduate students (assume that total enrolment is in the thousands). If a random sample of 10 students is selected from the school to be interviewed about their level of satisfaction with the quality of the school's programs, what is the probability that at least 9 of the students selected are undergraduate students?

This tends to: Why does harburg feel that "brother, can you spare a dime?" is a legitimate question, not just a plea from a beggar? with their hard work, these individuals had invested in their country and they deserved to be suitably rewarded. manual labor jobs were replaced by white-collar jobs, so construction workers had no more options. a dime was only a small amount of money that could feed an entire family for many days. all of the wealthy had retained their riches, while the poor had to suffer through the depression. 9+10=21Yes, my calculation says , it is possible.But only in other number base.Let me explain.9 + 10 = 21or, 19 = 21Assume that , 19 is a decimal number.and 21 is a n base number.As 19 is equivalent to 21,So 10 base 19 is equivalent to n base 21.So with the help of math I can get that,19 = 1 10^1 + 9 10^021 = 2 n^1 + 1n^0 = 2n + 1So , 2n + 1 = 19or, 2n = 18or, n = 9So finally, we can say that,10 base 19 = 9 base 21Thus 9+10=21 is possible
