Answer:

The width is 13, the length is 17


Step-by-step explanation:

You have to write an expression to represent the area of the rectangle. The width can be w, and the length can be 2w-9. Since the parking lot is a rectangle, you multiply the length by the width to get your area. w(2w-9) is 2w^2-9w=221. The only value of w that satisfies this equation when substituted is 13, so that is your width. 2(13)-9 is 26-9 is 17, so the length is 17.

What is x*x=15? (Basically make an equation that equals up to 15.)
rodikova [14]

Answer:

\displaystyle \sqrt{15} = x

Step-by-step explanation:

Be VERY careful. When it write out the equation that way, it will give the speculation of this:

\displaystyle 15 = x^2

Now, in this case, since you were extra explanatory about this [what is written in parentheses], two factors I know of that multiply to 15 are these:

** \displaystyle 15 = 2 \times 7\frac{1}{2}

I am joyous to assist you at any time. ☺️

Mrs. Dimitri purchased a case of yogurt cups. Out of every 10 yogurt cups, 6 are strawberry.
emmasim [6.3K]

Answer:

1) The fraction of yogurt cups that are strawberry is 18/30. (True)

2) There are a total of 60 strawberry yogurt cups. (False)

3) 60% of the yogurt cups are strawberry. (True)

4) 30% of the yogurt cups are NOT strawberry. (False)

Step-by-step explanation

Total number of yogurt cups are = 30

for every 10, 6 are strawberry

thats is for the whole 30 cups total number of strawberries are = 18

1) The fraction of yogurt cups that are strawberry,

that is the fraction of the total number of strawberries over the total number of cups which is 18/30

2) There are a total of 60 strawberry yogurt cups,

the total number of yogurt cups is 30 while that of strawberry is 18

3) 60% of the yogurt cups are strawberry,

which is 18/30 * 100% = 60%

4) 30% of the yogurt cups are NOT strawberry,

percentage of the remaining cups will be 100% - 60% = 40%

Answer:

I'm confused by the points:  

Why three points for each (A, B, C, and D)?: A: (0,6)(0,6)(0,6), etc.

Points A and B [(0,6) and (4,2)] are consistant with a straight line of the form y=-x+6.

Points C and D [(-6,8),(-8,10)]are on the line y=-x+2.  

A and B aren't related to C and D.

Find the value of x .. assume that segments that appear to be tangent are tangent .
Rus_ich [418]

Answer:

sqrt(277) =x

x is approximately 16.64331698

Step-by-step explanation:

This is a right triangle since 14 is tangent to the circle and 9 is a radius

We can use the Pythagorean theorem to solve this problem

a^2 +b^2 =c^2

9^2+14^2 =x^2

81+196 = x^2

277 = x^2

Taking the square root of each side

sqrt(277) = sqrt(x^2)

sqrt(277) =x
