Find the area of the shaded region. Use 3.14 for it and round your answer to the nearest hundreth.
Answers
Answer:
So we know the formula to calculate the area of the circular sector:
S=(r^2*π*a)/306°=
(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.
Step-by-step explanation:
r - radius of the circle
a - corner of the circular sector
S - surface

Point A = 0.62Point B = 7/9Point C = 10/9===================================================
Explanation:
Using a calculator, we get the following decimal approximations
1/3 = 0.3332/3 = 0.6677/9 = 0.77810/9 = 1.111Based on that, we see that 0.620 is between 0.333 and 0.667
We can say 0.333 < 0.620 < 0.667
which is the same as 1/3 < 0.62 < 2/3
So, 0.62 is between 1/3 and 2/3
0.62 will be placed at point A.
--------------
Since 7/9 = 0.778 is between 2/3 = 0.667 and 1, this means,
7/9 will go to point B.
--------------
Since 1.111 > 1, this means 10/9 > 1
Therefore 10/9 will go to point C

In the figure below, ABC is similar to XYZ . What is the length of ZX ? Enter only the number as an integer or decimal. An image shows two similar right triangles, A B C and X Y Z. Triangle A B C is smaller than triangle X Y Z. In triangle A B C, side A B is 2, side B C is 4, and side C A is 3. In triangle X Y Z, side X Y is 7, side Y Z is 14, and side Z X is labeled N.
Answers
Given:
Triangle ABC is similar to triangle XYZ.
In triangle ABC AB=2, BC=4, CA=3.
In triangle XYZ, XY=7, YZ=14, ZX=N.
To find:
The length of ZX.
Solution:
If two triangles are similar, then their corresponding sides are proportional.
Since [tex]\Delta ABC\sim \Delta XYZ[/tex], therefore
[tex]\dfrac{AB}{XY}=\dfrac{BC}{YZ}=\dfrac{CA}{ZX}[/tex]
[tex]\dfrac{2}{7}=\dfrac{4}{14}=\dfrac{3}{N}[/tex]
[tex]\dfrac{2}{7}=\dfrac{2}{7}=\dfrac{3}{N}[/tex]
[tex]\dfrac{2}{7}=\dfrac{3}{N}[/tex]
On cross multiplication, we get
[tex]2\times N=3\times 7[/tex]
[tex]2N=21[/tex]
Divide both sides by 2.
[tex]N=\dfrac{21}{2}[/tex]
[tex]N=10.5[/tex]
Therefore, the length of side ZX is 10.5 units.

A 12 ounce starbucks latte costs $3.36. What is the constant of proportionality that relates the codt in dollars,y,to the number of ounces,x,in a starbucks latte?
Answers
Answer:0.28
Step-by-step explanation:
3.36÷12= 0.28
The constant of proportionality is 0.28 dollars per pounds.
An equation is used to show the relationship between two or more numbers and variables.
Let y represent the cost in dollars for x number of ounces.
Since y is proportional to x, hence it van be represented by:
y = kx
where k is the constant of proportionality.
Given that:
A 12 ounce starbucks latte costs $3.36. Therefore:
3.36 = 12k
k = 0.28
