Answer:
The value of sine of angle XYZ is equal to 0.96.
Step-by-step explanation:
Given that,
Base, b = 4 cm
Height, h = 13 cm
We need to find the sinY.
Using Pythagoras theorem,
YZ² = XY² + XZ²
YZ² = 4² + 13²
YZ = 13.60 cm
Using trigonometry,
[tex]\sin Y=\dfrac{13}{13.60}\\\\\sin Y=0.96[/tex]
So, the value of sine of angle XYZ is equal to 0.96.

17. a = 104, b = 175
19. 144/252, 20/35
20. 14/21, 18/27
21. 16/48, 12/36
22. 219 grams
23. 5 milligrams
Step-by-step explanation:
Answer:
16. r = 20
t = 48
17. a = 104
b = 175
19. [tex]\frac{144}{20} =\frac{252}{35}[/tex]
7.2 = 7.2
20. [tex]\frac{27}{18}= \frac{21}{14}[/tex]
1.5 = 1.5
21. [tex]\frac{48}{16} =\frac{36}{12}[/tex]
3 = 3
22. [tex]\frac{8}{3} :\frac{584}{y}[/tex]
219 grams of peanuts
23. [tex]\frac{y}{2}: \frac{200}{80}[/tex]
50 milligrams of medication
Step-by-step explanation:
16. [tex]\frac{r}{32} =\frac{5}{8} =\frac{30}{t}[/tex]
8 · 4 = 32
5 · 4 = 20
r = 20
5 · 6 = 30
8 · 6 = 48
t = 48
17. [tex]\frac{52}{a} =\frac{10}{20} =\frac{b}{350}[/tex]
Here is a different method.
[tex]\frac{10}{20} =\frac{1}{2}[/tex]
52 · 2 = 104
a = 104
350 ÷ 2 = 175
b = 175
22.
[tex]\frac{8}{3} :\frac{584}{y}[/tex]
8 · y = 3 · 584
8y = 1752
8y ÷ 8 = 1752 ÷ 8
y = 219
23.
[tex]\frac{y}{2}: \frac{200}{80}[/tex]
y · 80 = 200 · 20
80y = 4000
80y ÷ 80 = 4000 ÷ 80
y = 50

Since they have the same x axis you have to find the difference from the y axis. I just add the two if one is positive and the other is negative so 2.9+(-7.2) = 10.1
A student was asked to identify the following numbers as rational or irrational. Determine if the student has made any mistakes. Choose ALL the INCORRECT answers. There may be more than one answer
Answer:
Yes they are wrong, rational & irrational ones down below.
Step-by-step explanation:
So, lets start this by asking, what is a rational and irrational number?
Rational numbers are literally any numbers that arent pi, e, or other symbols, as well as square roots.
Irrational numbers are exactly the opposite, being the numbers that are symbols, including square roots.
Note that the symbols listed above such as pi are values that are neverending.
Now, using what we know of rational and irrational numbers, let see which answers are rational and which are not.
So, we start off with:
-13/3
I do not see a square root.
I do not see a symbol such as pi either.
It is not a ever going number.(number that continues infinitly)
So -13/3 is a rational number.
Next we have [tex]\sqrt{37}[/tex]
immediatly we tell it has a square root.
So [tex]\sqrt{37}[/tex] is a irrational number.
Next we have 0.1234
This is not a every going number.
There isnt a square root.
And it isnt a symbol.
So 0.1234 is a rational number.
Next we have [tex]-\sqrt{100}[/tex]
Again, we can immediatly know it has a square root.
So [tex]-\sqrt{100}[/tex] is a irrational number.
Next we have -77
This is not every going.
It doesnt have a square root.
It doesnt have a symbol.
So -77 is a rational number.
Lastly we have [tex]-\sqrt{12}[/tex]
Like the other ones, we can imediatly tell it has a square root.
So [tex]-\sqrt{12}[/tex] is a irrational number.
Bascially, to answer further questions, here is the criteria for a number being rational:
It does not have a square root.It does not have a symbol.It is not a infinitly going on number.If one of these criterias are not met, then you know its a irrational number.
Hope this helps! :D

In a candy store, a $12.00 jar of candy is labeled, "30% off." What is the discount as a dollar amount?
Answer:
8.40
Step-by-step explanation: This means the cost of the item to you is $8.4. You will pay $8.4 for a item with original price of $12 when discounted 30%. In this example, if you buy an item at $12 with 30% discount, you will pay 12 - 3.6 = 8.4 dollars.
Answer:
The new total will be $8.40.
Step-by-step explanation:
The 30% off discount gives you $3.60 off of your purchase.

Pentagon ABCDE is similar to pentagon PQRST. If the side length of pentagon ABCDE is 6 times the side length of pentagon PQRST, which
statement is true?
.A
The area of pentagon ABCDE is 6 times the area of pentagon PQRST
The area of pentagon ABCDE is 12 times the area of pentagon PQRST.
Ос.
The area of pentagon ABCDE is 36 times the area of pentagon PQRST.
D.
The area of pentagon ABCDE is 216 times the area of pentagon PQRST,
Answer: c
Step-by-step explanation:
The area of pentagon ABCDE is 36 times the area of pentagon PQRST. Therefore, the option C is the correct answer.
What is a pentagon?Any five-sided polygon or 5-gon is referred to as a pentagon. A basic pentagon's interior angles add up to 540°. A pentagon might be straightforward or self-intersecting.
We know the formula for the area of a pentagon, therefore, the area of the pentagon PQRST can be written as,
A= 1/4 ×√(5(5+25)×a²
Given that the side of the side length of pentagon ABCDE is 6 times the side length of pentagon PQRST, therefore, the area of the pentagon ABCDE can be written as,
Area of a ABCDE = 1/4 ×√(5(5+25)×(6a)²
= 1/4 ×√(5(5+25)×36a²
= 36A
Therefore, the option C is the correct answer.

Finding volume for geometry using 3.14.
Answer:
[tex]V=405.04\:\mathrm{cm^3}[/tex]
Step-by-step explanation:
The volume of a cone is given by [tex]V=\frac{1}{3}\cdot r^2\pi\cdot h[/tex] (the area of the base multiplied by the height divided by 3).
In the given cone, we have [tex]r=6.1\:\text{cm}[/tex] and [tex]h=10.4\:\text{cm}[/tex]. Substituting in these values, we get:

Answer:
1. 20 half of 20 is 10(new radius),
10^10 = 100
100 x 3.14 = 314
314 divided by 2 = 157
2. 8 x 8 = 64, 64 divided by 2 ( x 1/2) = 32
half of 8 is 4(new radius)
4 ^4 = 16, 16 x 3.14 = 50.24
50.24 divided by 2 = 25.12

3. Half of 7 is 3.5(new radius)
Just find the area of a full circle since two semi circles make a full circle.
3.5^2 = 12.25
12.25 x 3.14 = 38.465,
21 x 7 = 147
147 + 38.465 = 185.465
4. Half of 6 is 3(new radius)
3^3 = 9
9 x 3.14 = 28.26, 28.26 divided by 2 = 14.13
11 x 6 = 66, 66 divided by 2 (x 1/2) = 33
14.13 + 33 = 47.13
5. 81 divided by 4 = 20.25
half of 20.25 is 10.125(new radius)
10.125 x 2 x 3.14 = 63.585 rounded = 63.59

A quadrilateral is shown on the graph below. If the dimensions of this
quadrilateral are scaled by a factor of 2, which equation models the
effect this scaling has on the area of the figure.
Answer:
Area of the image rectangle = 4(Area of the original rectangle)
Step-by-step explanation:
Length of the rectangle given in the graph = 4 units
Width of the rectangle = 2 units
Area of the rectangle = Length × Width
= 4 × 2
= 8 square units
Since, scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original}}[/tex]
2 = [tex]\frac{\text{Length of the image}}{\text{Length of the original}}[/tex]
Length of the image rectangle = 2(4)
= 8 units
Similarly, width of the image rectangle = 2(2)
= 4 units
Area of the image rectangle = 8 × 4
Area of the image = Area of the original × 4
Area of the image = 4(Area of the original)
Area of the image rectangle = 4(Area of the original rectangle)

Answer: 1) Using the order of operations, you first have to multiply the amount of each item by it's price, and then add those values. So for Pablo, you would do (0.50 x 1) + (0.75 x 3) + (1.25 x 3) and solve within the parentheses to get .50+2.25+3.75=$6.50
2) For Laurie, use the same method from #1. First multiply and then add, like so: (0.5 x 2) + (1.25 x 3) + (0.75 x 3) ---> 1+3.75+2.25, which equals $7
3) Laurie > Pablo

Help me in my math end test there are the things i need to learn. Please!!!!!
for the trapezoid/trapezium
the formula for finding the area of a trapezoid is A=(a+b)/2*h, and if you didnt know, a and b are always parallel.
for the parallelogram
it will always be b*h, this one is pretty easy to remember, also parallelograms include squares, rectangles, and anything with 4 sides.
the example
lets just say that we are missing a, which is the top one. now we have to fill in the missing little bit marked by a green square. this particular trapezoid is symmetrical, so we dont have to find the other side, but if it wasn´t, then you have to find the other side with the Pythagorean thoream. That is what we are going to do now. We have a and c and we need to find b in a²+b²=c², so plug in our values for a and c
(10)²+b²=(13)²
100+b²=169
now just isolate b and solve
b²=69
how to undo a square is by taking the square root of the other side of the equation
sqrt(69) is about 8.3
