Preeta’s book has 300 pages. Each day she reads 10 more pages than the day before. She finishes her book in 6 days. How many pag
Scilla [17]

Step-by-step explanation:

1. if the number of pages in the 1st day is 'x', then the 2d day - 'x+10', the 3d day - 'x+20', the 4th day - 'x+30', the 5th day - 'x+40' and the last day - 'x+50' pages;

2. if the sum of all the pages is 300, then it is possible to make up the equation:

x+x+10+x+20+x+30+x+40+x+50=300;

3. x=25, it means:

1st day - 25;

2d day - 35;

3d day - 45;

4th day - 55;

5th day - 65;

6th day - 75 pages.

What is the y-intercept of the graph of the function f(x) = x2 + 3x + 5?
agasfer [191]

Answer:

(0,5)

Step-by-step explanation:

If you plug in 0 in all the variables of x, f(x)=0+0+5

We know that f(x) is y...so y=5, while x=0

A rectangle is twice as long as it is wide. If its length and width are both
puteri [66]

Answer:

a rectangle is twice as long as it is wide . if both its dimensions are increased 4 m , its area is increaed by 88 m squared make a sketch and find its original dimensions of the original rectangle

Step-by-step explanation:

Let l = the original length of the original rectangle

Let w = the original width of the original rectangle

From the description of the problem, we can construct the following two equations

l=2*w (Equation #1)

(l+4)*(w+4)=l*w+88 (Equation #2)

Substitute equation #1 into equation #2

(2w+4)*(w+4)=(2w*w)+88

2w^2+4w+8w+16=2w^2+88

collect like terms on the same side of the equation

2w^2+2w^2 +12w+16-88=0

4w^2+12w-72=0

Since 4 is afactor of each term, divide both sides of the equation by 4

w^2+3w-18=0

The quadratic equation can be factored into (w+6)*(w-3)=0

Therefore w=-6 or w=3

w=-6 can be rejected because the length of a rectangle can't be negative so

w=3 and from equation #1 l=2*w=2*3=6

I hope that this helps. The difficult part of the problem probably was to construct equation #1 and to factor the equation after performing all of the arithmetic operations.

How many distinct proper subsets are there of the set N = {10, 50, 63, 15, 40, 55}?
ASHA 777 [7]

Answer:

Proper\ Subset = 63

Step-by-step explanation:

Given

N = \{10, 50, 63, 15, 40, 55\}

Required

Determine the proper subsets

This is calculated by:

Proper\ Subset = 2^n - 1

<em>Where n is the number of elements in the set.</em>

In this case,

n = 6

So:

Proper\ Subset = 2^n - 1

Proper\ Subset = 2^6 - 1

Proper\ Subset = 64- 1

Proper\ Subset = 63
