If X and Y are two points on number line then the distance between them is represented by

Answers

Answer 1

Answer:

Step-by-step explanation:

Let the point X be represented as (x1, y1) and the point Y be (x2, y2). The distance between the two points is expressed as;

D² = (x2-x1)² - (x2-y2)²

Take the square root of both sides;

√D² = √(x2-x1)² - (x2-y2)²

D = √(x2-x1)² - (x2-y2)²

Also the distance between X and Y can be represented as D = |X-Y|

In a study a researcher measured a plant to be 8 cm tall. If the plant continues to grow 2 cm every week, after how many weeks will the plant reach the height of 24 cm?

Answers

Answer:

8 weeks

Step-by-step explanation:

Given

[tex]Initial\ Height = 8cm[/tex]

[tex]Growth = 2cm[/tex] weekly

Required

Determine the duration it gets to 24 weeks

First, we need to represent the scenario as a function.

Let the number of weeks be w.

So:

f(w) = Initial Height + Growth * Number of Weeks

This gives:

[tex]f(w) = 8 + 2 * w[/tex]

[tex]f(w) = 8 + 2w[/tex]

When the duration is 24 weeks,

We have that:

[tex]f(w) = 24[/tex]

Substitute 24 for f(w)

[tex]24 = 8 + 2w[/tex]

Make 2w the subject of formula

[tex]2w = 24 - 8[/tex]

[tex]2w = 16[/tex]

Make w the subject of formula

[tex]w = 16/2[/tex]

[tex]w = 8[/tex]

Hence, it'll take the plant 8 weeks to get to 24cm

Carla is following a recipe that calls for a cinnamon-sugar mixture that is 5% cinnamon.

If she places 2 grams of cinnamon in a bowl, which equation will help her find how many grams of sugar to add to the bowl?

Answers

Answer:

Step-by-step explanation:

It's a proportion rather than an equation that you might be more accustomed to.

2/0.05 = x/ 0.95       Cross multiply

2 * 0.95 = x * 0.05    Divide by 0.05

2 * 0.95/0.05 = x

x = 38 grams of sugar should be added to the 2 grams of cinnamon.

There's another way to do it.

2/0.05 = (x + 2)/1      Cross multiply

2*1 = 0.05x + 0.1       Subtract 0.1 from both sides

1.9 = 0.05x

1.9/0.05 = x

x = 38

Which ever way you understand better is the answer. 100 / 100% is 1

I have a very expert technique that is very easy to changed decimal into mixed fraction

All you have to do is nevermind of the integer sign

So we will move on to 30.75

The first is write it in word so 30.75 is thirty and seventy five hundreths

Then analyze so 30 is the whole number and 75 is numerator then 100 is the denominator

So it is 30 75/100 then simplify it to the lowest terms

= 123/4 or 30 3/5

Find the number that if subtracted from 7 and 12, the product of the two numbers gives 104

Answers

6 is the number i think that

-1 is  the number that if subtracted from 7 and 12, the product of the two numbers gives 104

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

We need to find the number that if subtracted from 7 and 12, the product of the two numbers gives 104

We need to find two integer factors of the number 104 that multiply up 104 and differ by 12-7 = 5 units

104=2×52

104=4×26

104=8×13

If we consider the  unknown number as (-1) then

number that if subtracted from 7  

7-(-1)=8

number that if subtracted from 12

12-(-1))=13

8×13=104

Hence -1 is the number that if subtracted from 7 and 12, the product of the two numbers gives 104.
