Step-by-step explanation:
It sounds like you are looking for a rectangle.So to find the area you would multiply 7 by 4 to get 28 square feet for the area.
Answer:
4.5 ounces
Step-by-step explanation:
First dived 3 by 2 to figure out how much water she drinks in 1/3 of a hour.
Second, you take the answer 1.5 ounces per 13 of an hour and multiply it by 3.
Lastly, you get your answer 4.5 ounces of water in a hour.
1. 3 / 2 = 1.5
2. 1.5 x 3 = 4.5
Answer:
d = sqrt( a^2 + b^2)
Step-by-step explanation:
Formula
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x1 = a
x2 = 0
y1 = 0
y2 = b
Solution
d = sqrt( (0 - a)^2 + (b - 0)^2 )
d = sqrt( a^2 + b^2)
which is another way of writing the Pythagorean theorem.
The coefficients are the constants -2/3, 3, and -2. You're supposed to multiply these together to get one term with one numerical constant which is the coefficient for the whole expression.
This is just a bunch of multiplications, (-2/3)*x*3*y*(-2)*x, and so the commutative law applies, which says that you can rearrange a multiplication any way you want. So put the numbers together, and the x's together and the y's together.
( (-2/3)*3*(-2) ) * (x^3 * x) * y
I'm also using the associative law, which says that I can put those parentheses in and multiply those groups of things together first. I'll bet you never thought "commutative law" and "associative law" were things that anybody actually used.
To simplify, multiply those things in the parentheses. x^3 * x is x^4. The product of those constants (-2/3), 3 and -2 is one number which is the coefficient. Source(s): Randy P <span> · 8 years ago </span>
