Thandi received 15% discount on a dress that costs R1500. How much did she
pay?​

Answers

Answer:

She paid $1,275.00.

Step-by-step explanation:

I'm assuming you meant $1,500, so I'll be using that.

You can figure this out by subtracting 15% of 1,500 from 1,500.

15% of 1,500 is 225.

1500-225=1275

Therefore, 15% off of $1,500 is $1,275.

Felix drew two box-and-whisker plots to compare the same sets of data:

In the form of a paragraph, use complete sentences to describe some of the differences in the prices of the two sets of books. Refer to the box and whisker plots to justify your answer.

Answers

The first difference I noticed is the minimum price which is $3 for the first one and $7 for the second.
The maximum is also different which is $29 for the first one and $99 for the second one. The median $7 for the first set and $66 for the second set.
Lastly the inner quartile are different.
The first set has a lower quartile of $5.6 and upper quartile of $16.
The second set has a lower quartile of $26.8 and a upper quartile of $81.3.
The upper quartile represents the median of the upper region and lower is the median of lower region.

Answer:

In the first data set, there is little variation in the prices. Half of the books cost between $3 and $7, with one-fourth of the books priced between $5.40 and $7. This is easy to read from the graph, since the medians divide the data into 4 equal groups.

In the second data set, there is a large range of prices. There is no simple description of the data. Looking at the graph, there are 3 "halves" of the data: $7 to $66 or $59, $26.80 to $81.40 or $54.50, and $66 to $99 or $33. This range of values does not give much information about general book prices.

A line with a slope of 5 passes through the point (1,9). What is its equation in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.​

Answers

Answer:

y = 5x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5, then

y = 5x + c ← is the partial equation

To find c substitute (1, 9) into the partial equation

9 = 5 + c ⇒ c = 9 - 5 = 4

y = 5x + 4 ← equation of line

Jim paid a gym membership fee of $50, plus $20 per month. Jim has paid a total of $290 to thegym. Which equation matches this situation?​

Answers

Answer:

50+20x=290 or 50+(20x12)=290

Step-by-step explanation:

Answer:

50 + 20m = 290

Step-by-step explanation:

The answer is 50 + 20m = 290, because Jim paid a membership fee that was $50. Then each month he paid $20 because of his new membership. Jim never paid $50 a month, that was only his starter fee, but then gradually paid $20 every month so it would be 20m. Hope this helped.

Answer:

Read answer below :)

Step-by-step explanation:

So you know that the height is 12 cm, and the base is 27 cm at full. When they show you half, that's 13.5. So, having three sides in the entire base-length of 27 cms, you'll divide 27 by 3, in which case you get 9. Each the the base lengths are 9.

So the formula for volume is length * width * height. Knowing the width (13.5), the length (9), and height (12), multiply them. Your final answer is 1458 for all of it. For one side, divide by 6.

A rectangular goat pen has an area of 32 square meters and a perimeter of 24 meters. What are the dimensions of the pen?

Answers

Answer:

Breadth is 4 m and length is 8m

Step-by-step explanation:

Area of the rectangle = Length * breadth

Area of the rectangular goat pen= 32 square meters

Perimeter of the rectangular goat pen = 24 meters

Perimeter of the rectangle = 2(length + breadth)

          24= 2(l+b)

          12= length + breadth

         12- breadth = length ----------- equation A

Area = l*b

32= l*b

32= (12- b) *b

32= 12b- b²

b²-12b+32= 0------------------- equation B

Solving the quadratic equation by factorization

b²- 8b- 4b+32= 0

b(b-8) -4(b-8)= 0

(b-8) = 0

(b-4)= 0

b= 8 or b=4

As breadth is usually smaller than length then putting b= 4 in  equation A

gives

  12- breadth = length

12-4= length

length = 8

Hence breadth is 4 m and length is 8m

how do you solve for x

the similarity statement is abc~ xyz​

Answers

Answer:

m<X= 36.87 degrees

Step-by-step explanation:

Since the triangle abc and xyz are similar, hence;

m<C = m<Y

90 = x - 5

Add 5 to both sides

90+5 = x-5+5

95 = x

Swap

x = 95

m<Y = x - 5

m<Y = 95 - 5

m<Y = 90

Find m<X

Using the SOH CAH TOA

Opposite to m<X = YZ = 6

Adjacent = 8

Tan M<X = opp/adj

Tan m<X = 6/8

m<X = arctan(6/8)

m<X= 36.87 degrees

Answers

Answer:

No solution

Step-by-step explanation:

Equation C :

y = 6x + 9

Equation D :

y = 6x + 2

By comparing both the equations with slope-intercept form of the equation,

y = mx + b

Where, m = Slope of the line

And b = y-intercept

Slopes of both the lines C and D are common as 6,

Therefore, both the lines will be parallel.

And the set of parallel lines has no solution.

Therefore, given set of equations have no solution.
