6)a garden was square, but last year she made it makes or shortening one side 5 meters and the other 8 meters. If the area of the smaller garden is 180 m², then what was the area of her square garden​

Answers

Answer 1

Answer:

let dimention of original garden be x

then (x-8)(x-5) = 180

x^2 -13x -140 = 0

(x-20)(x+7)=0

x= 20 or x = -7

x = 20

original area = (20)^2

= 400 m^2

what is the mean, median, mode and range of 7, 2, 1, 4, 1

Answers

The mean is the total of all the values, divided by the number of values. To find the mean, we add up all the results and then divide them by the total number of values which is 5:

1 + 1 + 2 + 4 + 7 = 15

15 / 5 = 3.

The median is the middle number in a list of numbers ordered from smallest to largest, so the median is 2.

1, 1, (2), 4, 7

The mode is the value that appears most often in a set of data. In this case, the mode is 1.

1: 2
2: 1
4: 1
7: 1

The range is the difference between the highest value and the lowest value, so the range here is 6.

Highest value: 7
Lowest value: 1

7 - 1 = 6

Alice is standing on the roof of a 150 ft building. She looks down at an angle of depression of 15 degree and sees her friend bianca. How far away from the building is bianca

Answers

Answer:

559.70 ft

Step-by-step explanation:

Let D be the distance between building and Bianca.

Height of building H = 150 ft

Let there be a triangle ABC where, AC = height of building H= 150ft, AB = distance between Alice and Bianca and BC = D and therefore, ∠ABC = 15°.

Now in Triangle ABC , tanB = AC/BC

therefore, tan15° = 150/D

D = 150/tan15° = 559.70 ft

Therefore, the distance between building and Bianca D = 559.70 ft

Calculate the breadth if the perimeter is 16cm and the length is 5cm​

Answers

Step-by-step explanation:

Given,

perimeter - 16cm

length - 5cm

find breadth,

perimeter of rectangle = l × b

16cm = 5 × b

b = 16/5

b = 3.2 cm

Step-by-step explanation:

Given

perimeter (P) = 16 cm

Length(L) = 5 cm

breadth (b) = ?

We know

P = 2 (L + b)

16 = 2 ( 5 + b)

16 = 10 + 2b

2b = 16 - 10

2b = 6

b = 6 / 2

b = 3 cm

Bus A travels according to the function y = 125 /2 x where y is distance traveled in miles and x is time in hours. Bus B travels according to the graph below, where the distance y is a function of time x . Which bus travels faster? Include all necessary calculations in your final answer.

Answers

Answer:

Bus B travels faster.

Step-by-step explanation:

The graph of the question in the attached figure

we know that

the linear equation in slope intercept form is equal to

where

m is the slope

b is the y-intercept

x ---> is the time in hours

y ---> is the distance in miles

In this problem we have

Bus A

The slope of the linear equation represent the speed of the bus

so

The speed of bus A is

Bus B

Find  the slope

take two points from the graph

(0,0) and (3,200)

The formula to calculate the slope between two points is equal to

substitute

Compare the slope Bus A with the slope Bus B

therefore

Bus B travels faster.
