# Dpoiski2 Find the perimeter of a rectangle with l = 0.85 m and w = 0.4 m. A. 1.25 m B. 2.5 m C. 0.34 m D. 0.68 m Unsubscribe

QUESTION POSTED AT 18/01/2020 - 07:41 AM

For this question the answer is 2.5m (B)
You find this by: L=0.85m
W=0.4m

A rectangle had 4 sides (2 lengths and 2 widths)
So...
To find 1 length and 1 Width you do 0.85+0.4=1.25m
Now you want to find the other 2 sides (L and W)
You can do: the same method and add it to 1.25m OR...
You can do (I prefer this one): (0.85+0.4)x2=?
This is the same as 0.85+0.4=1.25
1.25x2=2.5m

### In 4 years, harry’s age will be the same as jim’s age is now. in 2 years, jim will be twice as old as harry will be. find their ages now.

The answer to this question would be:
Jim     =6 years
Harry =2 years

To answer this question, you need to translate the description into a  mathematical equation. If H= Harry's ages and J= Jim's ages, then the equation should be look like this:

1. H+4= J
2. (J+2)= 2(H+2)
J+2= 2H+4
J= 2H +2

If you put the 1st and 2nd equation together, the result would be:
H+4= J
H+4= (2H +2)
H-2H= 2-4
-H= -2
H=2

After that insert the H value to either 1st or 2nd equation.
H+4= J
2+4=J
J= 6

By the given scenario above, we can formulate two inequalities that best represent the scenario. We let x and y be the number of tables and chairs, respectively such that,
25x + 15y ≤ 285
x + y ≥ 16
The values of x and y if we temporarily change all the inequality signs to equal signs are 4.5 and 11.5, respectively. Since, it is not allowed for a number of item to be in negative, we can then say that the number of tables should be 4 and that of chair is 12.

### Find the range of the function y=-5x-7

Range is how far up or down the garph can go
basically the limits of y

find min and max of y

basically find the biggestor smallest the x can get to influence y
confusing sorry
when x is an even number, that number is still negative

so make that number as small as possible
if x=(big number that is negative)
we get -1/(5^(big number)) which basically makes it nigligible or almost 0

y=-7 is max

when x=big number (positive) we get very negative number

so range is from negative infinity to -7
basically y<-7
we choose < and not ≤ because the -5ˣ will never dissapear, it will just be very, very small

### A square photograph has a perimeter of 20 inches. What is the area of the photograph?

Area of square is 25 inches²

Step-by-step explanation:

Given : A square photograph has a perimeter of 20 inches.

We have to find the area of the photograph.

We know perimeter of square is 4a , where a is side of square

Given : perimeter of square = 20 inches

4a = 20

Divide both side by 4, we get,

a = 5 inches

Also, Area of square = side × side

Area of square = 5 × 5

Area of square = 25 inches²

Thus, area of square is 25 inches²
