Answer:
21, 23, 25
Step-by-step explanation:
Ok, so this one may seem a little tricky, so I'll try to explain it as best as I can. :)
So because they are consecutive odd numbers, that means they are odd numbers that are one after the other. This means each number is 2 apart from the next. So by using this, we know that there is a difference of 6 between the highest and lowest number. Now let's try and make an equation:
3o + 6 = 69
Now in order to get O by itself we have to subtract 6 from both sides:
3o = 63
Now we just have to divide by three on both sides:
o = 21
So now, we know that the lowest number is 21, but we have to add 2 to get 23, and then another 2 to get 25.
Hope this helps :)
Answer:
The relationship is linear.
Step-by-step explanation:
A linear relationship is a trend in the data that can be modeled using a straight line, such that a relationship between two variables x and y is linear if the rate of change is constant. That is, whenever x increases by 1, and it always increases by the same constant.
The constant by which y increases as x increases by 1 is called the slope and is denoted by the letter m. Being b the y-intercept, the linear relationship is modeled by the expression:
y=m*x + b
In this case x represents the minutes and y is the total number of pieces put together, so that each time x (minutes) increases by 1, "y" increases by 5 pieces. So knowing that you have already collected 253 pieces, the expression of the linear relationship is:
y=5*x + 253
The relationship is linear.
X² - 4x + 4 = 0
(x-2)(x-2) = 0
the equation has one root mainly 2 with multiplicity 2
the answer is a
Answer:
or
12.57
Step-by-step explanation:
I have a <u>circular</u> piece of fabric I am going to make a tablecloth. The <u>radius</u> of the fabric <u>is 2 meters</u>. What is the <u>area</u> of the tablecloth I can make
Essentially, you are attempting to find the area of a circle with a radius of 2 meters.
The formula for an area of a circle is 
, or pi times radius squared.
Plugging in 2 meters as your radius, that gets your answer to be , or 12.57 in decimal.
