Jason wants to cut a rope that is 60 feet long into several equal pieces with nothing left over. How many pieces will he have if the length of each piece is the greatest integer possible?
Answers
Answer:
2 pieces, 30ft each
Step-by-step explanation:
rope : 60ft long
we are trying to figure out how many equal pieces we can cut the rope into with the length of each piece to be the greatest possible integer:
if jason wants the length of rope to be the longest than the answer is 2, if he divides the length of 60 by 2, each piece will be 30 feet long. If he divides the rope by any number larger, each piece will be shorter than 30 feet, and he wants the piece to be the largest possible length.
The answer is 2 pieces and 30ft

How many solutions does the following system of equations have? y=5/2x+2 and 2y=5x+8
Answers
Answer:
No solutions.
Step-by-step explanation:
y = 5/2x + 2
2y = 5x + 8
Plug the first equation into the second.
2(5/2x + 2) = 5x +8
5x + 4 = 5x + 8
5x + 4 cannot equal 5x + 8, so this system of equations has no solutions.

Answers
Answer:
linear pair postulate
Step-by-step explanation:
The linear pair postulate is the missing step.
What's the meaning of a linear pair of lines?Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines.
What is a Postulate?Postulate statement received without evidence. Axiom is any other name for postulate. for instance, if you understand that Pam is 5 feet tall and all her siblings are taller than her, don't trust her if she says that all her siblings are at the least 5 toes tall.

An isosceles triangle has two congruent side lengths of 20 inches.
The base of the triangle has a length of 32 inches. What is the height of the
triangle?
12 inches
10 inches
15 inches
Answers
Answer:
h = 12
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2
The legs are 32/2 = 16 and the height h
The hypotenuse is 20
16^2 + h^2 = 20^2
256 + h^2 = 400
h^2 = 400-256
h^2 = 144
Taking the square root of each side
h = sqrt(144)
h =12

What is the area of the shaded face?
Answers
Answer:
The area of the face is 15 cm^2
Step-by-step explanation:
The formula for volume is
V = Bh where B is the area of the base and h is the height
90 = B * 6
Divide each side by 6
90/6 = 6B/6
15 = B
The area of the face is 15 cm^2
Answer:
15cm^2
Step-by-step explanation:
width will be 6cm since its side face is square.
V=lwh
90cm^3=l*6cm*6cm
90cm^3=36cm^2*l
l=90cm^3/36cm^2
l=2.5cm
so the area of the shaded face will be..
A=l×W
A=2.5cm*6cm
A=15cm^2

D. Make a list
Step-by-step explanation:
You can tell that this is the correct answer just by the wording. First, guess and check doesn't make sense as a strategy by which to plan which bracelets you can sell. Neither does working backwards. Finding a pattern doesn't apply to this sort of thing. So therefore, the answer is make a list.

What is the value of the 3 in 630
Answers
Answer:
hey mate, here is your answer. Hope it helps you.
Step-by-step explanation:
We can write 630 in expanded form as:
630 = 600 + 30 + 0
and in words:
630 = 6 hundreds, 3 tens and zero ones
the value 6 is 600
and the place value of 3 is 30 and the face value is 3 in the number 630.
The number can be written in the expanded form as 600 + 30 + 0 and the face value is 3 in the number 630.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that:
The number is 630
As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
The number 630 can be written as:
630 = 6x100 + 3x10 + 0x1
630 = 600 + 30 + 0
The above expression represents the expanded form of the number 630.
In words:
630 = 6 hundred, 3 tens, and zero ones
The value 6 is 600
The place value of 3 is 30 and the face value is 3 in the number 630.
Thus, the number can be written in the expanded form as 600 + 30 + 0 and the face value is 3 in the number 630.
