Answer: y = 9x
Step-by-step explanation:
Li needs to use 9 beads for each inch of necklace.
X = Length of Necklace
Y = Number of beads needed
y = 9x
For instance, assuming a necklace is 8 inches long, how many beads will be needed;
= 9x
= 9 * 8
= 72 beads

its an obtuse angle
obtuse, because it's not a acute because its larger not smaller, and it's not a right because its not at a 90 degree angle, and it's not straight because that angle isnt completely straight
Which transformations could be performed to show that △ABC is similar to △A"B"C"?
a reflection over the x-axis, then a dilation by a scale factor of 3
a reflection over the x-axis, then a dilation by a scale factor of One-third
a 180° rotation about the origin, then a dilation by a scale factor of 3
a 180° rotation about the origin, then a dilation by a scale factor of One-third
Answer:
D
Step-by-step explanation:
Because I said so
The transformations could be performed to show that △ABC is similar to △A"B"C" is a 180° rotation about the origin, then a dilation by a scale factor of One-third .
What is a transformation of a graph?Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph. It's a common type of problem in algebra, specifically the modification of algebraic equations.
According to the question
In △ABC
AB = 3 units
BC = [tex]\sqrt{90}[/tex] units
CA = 9 units
In △A"B"C"
A"B" = 1 units
B"C" = [tex]\sqrt{10}[/tex] units
A"C" = 3 units
Now, the transformations could be performed to show that △ABC is similar to △A"B"C"
i > Rotate △ABC 180° about the origin
ii > then a dilation by a scale factor of One-third as we can observe that
each side of △ABC = 3 * each side of △A"B"C"
Hence, the transformations could be performed to show that △ABC is similar to △A"B"C" is a 180° rotation about the origin, then a dilation by a scale factor of One-third .

The table below contains data on how many pages were read for homework in Mr. Kaplinsky's third period. The equation of the line of best fit for the data is y = 28.3x + 4.8. Which two statements accurately describe the slope for the line of best fit? About 28.3 pages were read each hour. The most that any student can read is 4.8 pages per hour. For each additional hour spent reading, approximately 4.8 additional pages can be read. If a student starts reading faster, they will read 28.3 more pages in each additional hour they read. If a student reads for 1 hour longer than another person, they will have read approximately 28.3 more pages.

Can I get help solve to find X?
==========================================
Explanation:
The same tickmarks on each side of the triangle tells us that all three sides are the same length. This triangle is equilateral.
All equilateral triangles have each of their three angles at 60 degrees (they are considered equiangular). This is because 60+60+60 = 180.
Set 2x+32 equal to 60 and solve for x
2x+32 = 60
2x = 60-32
2x = 28
x = 28/2
x = 14
As a check,
2x+32 = 2*14+32 = 28+32 = 60
which helps confirm the answer.
Janiya hiked 4/5 of a mile in 1/3 of an hour what is the hiking speed in miles per hour
Answer:
Janiya has a speed of [tex]2\frac{2}{5}[/tex] miles per hour.
Step-by-step explanation:
Given that:
Distance covered = 4/5 of a mile
Time taken to cover the distance = 1/3 of an hour
Speed is defined as the distance travelled in a certain time.
Speed of Janiya = [tex]\frac{Distance}{Time}[/tex]
Speed of Janiya = [tex]\frac{\frac{4}{5}}{\frac{1}{3}}[/tex]
Speed of Janiya = [tex]\frac{4*3}{5*1}[/tex]
Speed of Janiya = [tex]\frac{12}{5}[/tex]
Speed of Janiya = [tex]2\frac{2}{5}[/tex] miles per hour
Hence,
Janiya has a speed of [tex]2\frac{2}{5}[/tex] miles per hour.

Answer:
yes it can
Step-by-step explanation:
Answer:
Yes, m can be a fraction.
Step-by-step explanation:
m in y=mx+b stands for slope, and slope is rise/run, so it most definitely can be a fraction. BUT, keep it as 5/4 or 1.25 when writing it so you don't confuse yourself next time ;)
Suzie bought a sweater at the sale price of $25. The original cost of the sweater was $40. What percent represents the discount that Suzie received when buying the sweater? A.15%, B.37.5% C.60% D.62.5%
Answer:
B.37.5%
Step-by-step explanation:
Step one:
given
The sale price of $25
The original cost of the sweater was $40
Required:
The percent discount
Step two:
% discount= change in price/original price *100
%discount = 40-25/40 *100
% discount= 15/40*100
% discount = 0.375*100
% discount =37.5%

The sides of two similar trapezoids are in a ratio of 1:3. The area of the smaller trapezoid is 12 squared inches. Find the area of the larger trapezoid
Answer:
108 sq in.
Step-by-step explanation:
The ratio of the areas is the square of the ratio of the sides.
Side ratio 1:3
Area ratio 1:9
The side of the larger trapezoid is 3 times the side of the smaller trapezoid.
The area of the larger trapezoid is 9 times the area of the smaller trapezoid.
9 * 12 sq in. = 108 sq in.
