Answer 1

Answer:

1 / We have the area of a rectangle ABCD = 8 x 16 = 128 ft²

2 / Find the area of an isosceles Δ DEF:

The base of the isosceles ΔDEF => DF = DC- FC = 16 -12 = 4 ft

So the area of Δ DEF = 1/2 (DF x EH) = 1/2 (4 x 6) = 12 ft²

3 / Area of the irregular shape = area ABCB + Area DEF = 128 + 12 = 140 ft²

Answer:

length = 20cm

breadth = 8cm

Step-by-step explanation:

solution;

length(l) = x + 12

breadth(b) = x

perimeter (p) = 56 cm

we know that,

perimeter(p) = 2(l + b)

or, 56 = 2(x + 12 + x)

or, 56 = 2(2x + 12)

or, 56 = 4x +24

or, 56 - 24 = 4x

or, 32 = 4x

or, 32 / 4 = x

x = 8

now

putting the value of x in length and breadth

length = x+ 12

=8 + 12

=20cm

breadth = 8cm

Answer:

A: x=3

Question :

Gabriel has a candy box containing 9 chocolates candies and 12 lollipops. If he choose 2 of them at random.

a) What is the probability that he gets 2 lollipops?

b) What is the probability that he gets 2 chocolates?

c) What is the probability that he gets at least 1 lollipop and 1 chocolate?

Answer:

First we need to calculate the total no. of items. In this case it is the no. of chocolate candies + the no. of lollipops which is, 9 + 12 = 21.

Now we can solve the questions.

a) P (2 lollipops) = 2/21.

b) P (2 chocolates) = 2/21.

c) P (at least 1 lollipop & 1 chocolate) = 2/21.

Note : P(x) is read as probability of getting x is....

Answer:

A)21/2

y=-2/3x-5 slope and y-intercept ​

Answers

Answer:

Slope = 2/3

Y-intercept = -5

Step-by-step explanation:

Since the equation is written in y = mx + b format. The m is the slope and b is the y-intercept. In place of m is 2/3 and in place of b is -5. Therefore, the slope is 2/3 and the y-intercept is -5.

hope this helps!

Maybe brainliest?

The equation of line is y = ( -2/3 )x - 5 , where the slope is m = -2/3 and the y intercept is b = -5

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

y = ( -2/3 )x - 5

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

Substituting the values in the equation , we get

Slope m = ( -2/3 )

The y-intercept b = -5

Hence , the equation of line is y = ( -2/3 )x - 5

Give the coordinates of the Image if the pre-image △ JKL is dilated by 3/2.

Answers

Lucky for me I just learned this lol
J: 3,6
K: stuck on this one because if you multiply one by 3/2 you get 3/2 so I don’t know
L:6,0


Able to get what I got, you have to multiply 3/2 by the the x and y axis. For example if x is “6” you’ll get 9. And so on.

Answer:

J'(3, 6), K'(1.5, 1.5), L'(6, 0)

Step-by-step explanation:

△ JKL is dilated by 3/2

This transformation will result in the coordinates:

(x, y) → (3/2x, 3/2y)

Apply the rule:

J(2, 4) → J'(3/2*2 = 3, 3/2*4= 6) = (3, 6)K(1, 1) → K'(3/2*1 = 1.5, 3/2*1 = 1.5) = (1.5, 1.5)L(4, 0) → L'(3/2*4 = 6, 3/2*0 = 0) = (6, 0)

3. The average of two numbers is 55. If their positive difference is 64, then determine the two numbers algebraically.

Answers

Answer:

the numbers are 41 and 23

Step-by-step explanation:

Given data

let the numbers be x and y

x+y/2= 55

cross multiply

x+y= 110----------1

positive difference is 64

x-y= 64-----------2

solve 1 and 2

x+y= 110

x-y= 64

from 1

x= 110-y

put the value of x in 2

110-y-y=64

110-2y=64

110-64=2y

46=2y

y= 46/2

y=23

put y= 23 in 2

x-23= 64

x= 64-23

x=41

prove 151^3-25^3 is divisible by 126

Answers

9514 1404 393

Answer:

  151 -25 = 126 is a factor of the difference of those cubes

Step-by-step explanation:

The expression can be factored as ...

  a^3 -b^3 = (a -b)(a^2 +ab +b^2)

  151^3 -25^3 = (151 -25)(151^2 +151·25 +25^2)

  = 126(151^2 +151·25 +25^2)

That is, 126 is a factor of the difference of the given cubes. The difference is divisible by 126.

Your calculator tells you 151^3 -25^3 = 126 · 27201.

The bonds mature on October 31, 2029. Bondholders have the option of calling (demanding payment on) the bonds on October 31, 2019, at a redemption price of $54 million. Market conditions are such that the call is not expected to be exercised. Management intended to refinance $11.2 million of its 10% notes that mature in May 2019.
