Answer:

A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .

A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .

If a line is horizontal the slope is zero. This is a constant function.

If a line is vertical the slope is undefined (see below).

The length of a rectangular pool is 4 meters less than twice the width. if the pool's perimeter is 88 meters, what is the width?

Usimov [2.4K]

W=x
L=2x-4
Perimeter=88
Perimeter=2(l+w)
88=2(2x-4+x)
88=4x-8+2x
88+8=4x+2x
96=6x
96/6=x

Alex wrote ten different digits on one red card and nine blue cards, only one digit per card. If he multiplies the digit on the

ch4aika [34]

Answer:

The digit written on the red card is 8

Step-by-step explanation:

Allen wrote ten different digits on one red card and nine blue cards. one digit per card is permitted.

He multiplies the digit on the red card by the sum of all the digits on the blue cards he will get 296 . Mathematically this can be represented below .

let

digit on the red card = a

sum of digit on the nine blue cards = b

ab = 296

Each card has only a digit in it. Since the cards occupies only ten different digit numbers, the numbers will be 0, 1 ,2 , 3, 4 , 5 , 6 , 7 , 8 and 9 .Out of the digits only one of them is written on the red card . The remaining number should then be summed.

ab = 296

b = 296/a

If you divide 296 by the only digit on the red card you will get the sum of the digit on all the blue cards. The digit on the red card must be the number from 0 to 9.

Therefore,

let us divide 296 by any single digit from 0 to 9 and know if the value is the sum of the remaining digits.

b = 296/8

b = 37

296 divided by 8 will give 37 . Let us check if the remaining digits will sum to 37.

0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 9 = 37

The digit written on the red card is 8

Thulani goes to the library every 7 days. He goes to the market every 4 days

emmasim [6.3K]

Thulani goes to both the library and the market for 5 more times during the year.

Step-by-step explanation:

Thulani goes to the library every 7 days. He goes to the market every 4 days.

We have to calculate the Least Common Multiple (LCM) to analyze the next common day on which he will go to both places.

The factors of 7 are: 1 x 7

The factors of 4 are: 2 x 2

Therefore, the LCM would be = 1 x 7 x 2 x 2

LCM = 28

LCM indicates that Thulani will go to both places on every 28th day.

To calculate the number of times (n) he will go to both places on same day. We can use the formula mentioned below:'

$n = \frac{Number of days}{frequency}$

Here frequency represents the LCM = 28.

The number of days are:

August: 30 (we are excluding 1st August)

September: 30

October: 31

November: 30

December: 31

Total = 152

By putting the values in formula, we get

$n = \frac{152}{28}$

n = 5.42

As, the number of times can only be a whole number. Therefore, Thulani goes to both the library and the market for 5 more times during the year.

Find the value of x.

hjlf

Answer:

Step-by-step explanation:

I realize that the time is passed.... but FYI

BD is Geometric Mean

That's mean BD² = 6 × 5 = 30 ⇒ BD = √30

x² = BD² + 6² = 30 + 36 = 66 ⇒ x = √66

y = √55
