Answer: 36
Step-by-step explanation:
Given
The ratio of Mary's to Helen's necklaces is 25:9
Mary has 100 necklaces
Suppose Helen has x necklaces
Therefore the ratio can be written like
So, Helen has 36 necklaces
Reflection across the y-axis on a coordinate plane.
What is the short definition of a coordinate plane?
Two number lines combine to produce the coordinate plane, a two-dimensional surface. The x-axis is a single horizontal number line. The y-axis is a vertical number line, which is the other number line. A place known as the origin is where the two axes collide. The coordinate plane allows us to graph points, lines, and more.
What is reflaction of coordinate plane?
Transformation is the process of making each point in a shape appear at the same distance on the other side of a specified line.
The term "line of reflection" refers to introspection with relation to that line. A line is crossed to flip the image.

Note that a sector is the area bounded by two radii and the
included arc. When trying to calculate for the area of the sector, you’ll use
the formula A=n/360 (pi)(radius)^2. Remember that the n in the formula refers
to the measure of the central angle in degrees. Since the given data in the
problem is in radians term, you can convert it by multiplying 1.25 to 180/pi.
Then you can now input the converted value to the formula of finding the area
of the sector.<span> </span>
Answer:
D
Step-by-step explanation:
y>-3x+1 Negative slope
y<u><</u>x+2 Positive slope
< or > have dotted line
<u><</u> or <u>></u> have a solid line
> or <u>></u> means solutions are above the line
< or <u><</u> means solutions are below the line
The one with negative slope has a dotted line and solutions above it.
The one with positive slope has a solid line and solutions below it.
