Let n = total number of babies born
Let n₁ = 34 be the number of boy babies born.
Let n₂ = number of girl babies born.
Therefore
n₁ + n₂ = n
34 + n₂ = n
n₂ = n - 34 is the numbe of girl babies born.
Because the 54% of babies born in the week were boys, therefore
34/n = 54%
or
34/n = 0.54
Multiply each side by n.
34 = 0.54n.
n = 34/0.54 = 62.96
We can only have countable number of babies, therefore
n = 63.
n₂ = n - 34
= 63 - 34
= 29
Answer: 29 girl babies were born in the week.
I believe that the general form would be <span>2x +4y+ 2 = 3y + 5 </span>
2x + 4y + 2 - 3y - 5 = 0
<span> 2x + y - 3 = 0 </span>
Answer:
0.6 I'm also sorry if I get it wrong
Answer:
======================================================
Explanation:
The fraction 1/4 is equivalent to the decimal form 0.25
We multiply 0.25 with each coordinate, of each point.
For example, let's focus on point L which is at (2,-1)
- x = 2 becomes x = 0.25*2 = 0.5
- y = -1 becomes y = 0.25*(-1) = -0.25
Point L(2,-1) moves to L ' (0.5, -0.25) which will move it closer to the origin, which shrinks the image. Use this idea for the remaining points.
Note: this trick only works if the center of dilation is the origin.
Given:
The graphed point is (60,-20).
To find:
The ordered pair that would form a proportional relationship with the given point.
Solution:
If y is proportional to x, then
Where, k is the constant of proportionality.
For the given point,
For option (A),
For option (B),
For option (C),
.
The point (-30,10) gives the same value of the constant of proportionality. So, the point (-30,10) forms a proportional relationship with the given point.
Therefore, the correct option is C.
