A square has sides 10x. Write and simplify an expression for the perimeter of that square.A rectangle has a length of 2x+7 and a width of 3x+8y. Write and simplify an expression for the perimeter of that rectangle.
Answers
square has 4 equal sides
so if th legnth of 1 side is x then total perimiter=4x
legnth of side is 10x
therfor perimiter=40x
rectanglepermiter has 2 pairs of sides with same legnth
RP=2L+2W=2(L+W)
L=2x+7
W=3x+8y
so
RP=2(2x+7+3x+8y)
RP=2(5x+8y+7)
RP=10x+16y+14
square=40x
rectangle=10x+16y+14
There are 4 equal sides of a square, so Perimeter = side length * 4
Perimeter expression - (4)10x
The perimeter of the square is 40x
2. Rectangle:
There are 4 unequal sides of a rectangle, so Perimeter = 2l + 2w
Length: 2x+7
Width: 3x+8y
Perimeter expression - 2(2x+7) + 2 (3x+8y)
(2x+7) *2 = 4x + 14
(3x+8y) *2 = 6x+16y
(4x +14) + (6x + 16y)
4x+6x +16y+14
The perimeter of the rectangle is 10x + 16y + 14

The value of 3 - 22 tenths or 3 - 2.2 is determined as 0.8.
What is tenths?
Tenths are a way of expressing fractional parts of a whole number, where one whole is divided into ten equal parts.
So, if we have 22 tenths, it means we have 22 out of the 10 equal parts of a whole. This can also be written as 2.2, where the number after the decimal point (2) represents the number of tenths.
To find the value of 3 - 22 tenths, we can subtract 22 tenths from 3 as shown below.
The given expression in tenths;
= 3 - 22 tenths
The solution is calculated as follows
= 3 - 2.2
= 0.8
Thus, the value of 3 - 22 tenths or 3 - 2.2 is determined as 0.8.

b. How many ants will be in the farm on Day 91?
Answers
Answer:
a)10
b)5120
Step-by-step explanation:
Given that number of ants double after every ten days, form a table that shows numbe of ants from day 1 to day 91
Day Number of Ants
1 10
11 20
21 40
31 80
41 160
51 320-----------------given
61 640------------------given
71 1280----------------given
81 2560
91 5120
Using the given values for number of ants and the number of days, you can notice the trend for values of days and number of ants.After every ten days, number of ants doubles.Using this information, you can navigate backwards up to day 1 and forward up to day 91
C.The expression is 3(p + 10). It takes 60 minutes to shape and fire 10 pots.
D.The expression is 3p + 10. It takes 40 minutes to shape and fire 10 pots.
Answers
Answer:
D. The expression is . It takes 40 minutes to shape and fire 10 pots.
Step-by-step explanation:
Let the number of pots in a batch = p
Now, one pot takes 3 minutes to get in a shape.
Then, 'p' pots will take minutes to get in a shape.
Also, it takes 10 minutes to fire one batch of pots.
Thus, the expression for the time taken to form one batch of pots =
So, when number of pots = 10 i.e. p= 10.
Time taken to fire the pots = = 30+10 = 40
That is, 'It takes 40 minutes to shape and fire 10 pots'.
Thus, option D is correct.
= 3p + 10
3x10 + 10 = 40 minutes for a batch of 10 pots
therefore D is the correct answer
