Triangles ABC and XYZ are similar figures, because angles A, B, and C are congruent to angles X, Y, and Z, respectively.
If side AC equals 3 cm, BC equals 9 cm, and XZ equals 15 cm, what is the length of side YZ?
Answer:
45cm
Step-by-step explanation:
Since they are simliar, they are proportional.
SO, you can do AC/XZ = BC/YZ
You can also see that XZ is 5 times larger than AC
SO multiply BC by 5.

Write the equation of the circle:
center: (-9, 0), diameter: 10
Answer:
[tex](x+9)^2+y^{2}=25[/tex]
Step-by-step explanation:
The equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex] is the center of the circle and [tex]r[/tex] is the radius of the circle.
Given the circle's diameter is [tex]d=10[/tex], then its radius is [tex]r=\frac{10}{2}=5[/tex].
Therefore, the equation of the circle is [tex](x+9)^2+y^{2}=25[/tex]
2. A bag contains 5 red marbles, 3 blue marbles, 6 white marbles, and 2 green marbles.
A. You choose one marble at random. Find the probability that you will choose a
white marble.
B. You choose one marble at random. Find the probability that you do not choose a red
marble.
I
C. You choose one marble at random, put the marble aside, then choose a second
marble at random. What is the probability that both marbles are blue?
D. You choose one marble at random, put the marble back in the bag, then choose a
second marble at random. What is the probability that you choose a red marble
and then a green marble?
Answer:
Step-by-step explanation:
5 red
3 blue
6 white
2 green
total 16 marbles.
Note: P(E) = probability of event E happening
P(~E) = probability of event E NOT happening.
We usually leave probabilities in fractions whenever possible because they will not be subject to round-off errors.
A. choose one marble at random.
P(W) = 6 white / 16 total = 3/8
B. choose one marble at random.
P(~R) = (16-5)/16 = 11/16
C. choose one marble at random, then a second one without replacement,
there will be 3 blue out of 16 at the beginning, then if successful, there will be 2 blue out of 15.
P(BB) = (3/16)*(2/15) = 1 / 40
D. choose two with replacement
5 red out of 16 for first draw, still 5 red out of 16 for second draw.
P(RR) = (5/16)^2 = 25/256

3. If 2x +9 32, then x could be
11.5?
Answer:
Yes
Step-by-step explanation:
We can see step by step how to solve for x, and get 11.5:
2x+9=32
Subtrract the 9 from both sides. You should always try to get the number on one side, and the variable on the other:
2x+9-9=32-9
=
2x=23
In the end, once the number values are on one side, and the variable value on the other, you want you varaible to be 1.
When I mean 1, I mean you want 1x, or just x.
Here we see 2x=23, meaning we need to divide both sides by 2, to get 1x:
2x/2=23/2
=
x=11.5
So x equals 11.5, and you were correct.

Helppppppp meeeeeeee
Answer:
32
Step-by-step explanation:
In order to find the measure of angle A we must first find x
If you didn't know, supplementary angles add up to equal 180
Hence, 2x - 16 + 5x + 28 = 180
( Note that we just created an equation that we can use to solve for x )
We now solve for x using the equation that we created
2x - 16 + 5x + 28 = 180
Combine like terms
7x + 12 = 180
Subtract 12 from both sides
7x = 168
Divide both sides by 7
We're left with x = 24
Now to find Angle a
To find Angle A we simply substitute 24 for x in 2x - 16
* Substitute 24 for x *
2(24) - 16
Multiply
48 - 16
subtract

Sandy went to her local zoo where 50% of it's exhibits featured reptiles. If the zoo features 44 exhibits in total, then how many of the zoo's exhibits feature reptiles?
Answer:
22 exhibits
Step-by-step explanation:
We are told from the above question that:
Sandy went to her local zoo where 50% of it's exhibits featured reptiles.
If the zoo features 44 exhibits in total, then the number of the zoo's exhibits that feature reptiles is calculated as:
50% of 44
50/100 × 44
= 50 × 44/100
= 22
Therefore, the number of the zoo's exhibits that feature reptiles is 22 exhibits.

If two angles are both vertical and supplementary, can we determine the angles? Is it possible to be both vertical and complementary? If so, can you determine the angles? Explain how you know.
Answer:
i. Two angles can be vertical and supplementary.
ii. Yes, we can determine the angles.
Step-by-step explanation:
When two angles are vertical, it implies that they are equal (with respect to vertical opposite property). While two angles are supplementary if and only if they add up to 180 degrees .
It is not mandatory for the two angles to be beside each other so as to be supplementary. So that in this special case, the only measure of angles that can be both vertical and supplementary is 90 degrees .

Determine whether the sequence is arithmetic or geometric. Sequence 1: –10, 20, – 40, 80, ... Sequence 2: 15, – 5, – 25, – 45, ... Which of the following statements are true regarding Sequence 1 and Sequence 2.
Answer:
geometric
arithmetic
Step-by-step explanation:
there are no statements to check. you did not copy them in.
but I can solve the first part of the question.
sequence 1 :
-10, 20, -40, 80, -160, 320, -640, ...
I extended the sequence by a few more terms.
but it is clear that each new term is the previous term multiplied by -2.
since the sequence is built by multiplication, it is geometric.
sequence 2:
15, -5, -25, -45, -65, -85, ...
so, it is clear that each new term is the previous term subtracted by -20.
since the sequence is built by adding or subtracting, it is arithmetic.
Given that√7=2.65 and √70=8.37,find the value of
(a)√0.07
(b)√0.0007
(c)√0.7
(d)√0.007
(e)√0.000007
(f)√0.00007
Answer:
A) 0.265
B) 0.0265
C) 0.837
D) 0.0837
E) 0.00265
F) 0.00837
Step-by-step explanation:
We are given;
√7 = 2.65 and √70 = 8.37
A) √0.07 can be rewritten as;
√(7 × 1/100)
Let's deal with the digits in the bracket.
Square root of 100 is 10. Thus;
√(7 × 1/100) = (1/10)√7 = (1/10) × 2.65 = 0.265
B) √0.0007
Rewrite to get;
√(7 × 1/10000)
Square root of 1/10000 is 1/100
Thus;
√(7 × 1/10000) = (1/100)√7 = (1/100) × 2.65 = 0.0265
C) √0.7
Like above;
√0.7 = √(70 × (1/100))
>> (1/10)√70 = (1/10) × 8.37 = 0.837
D) √0.007
Like above;
Rewrite to get;
√(70 × 1/10000)
Square root of 1/10000 is 1/100
Thus;
√(70 × 1/10000) = (1/100)√70 = (1/100) × 8.37 = 0.0837
E) √0.000007
Rewritten to;
√(7 × (1/1000000))
√(1/1000000) = 1/1000
Thus; √(7 × (1/1000000)) = 1/1000 × √7 = 1/1000 × 2.65 = 0.00265
F)√0.00007
Rewritten to;
√(70 × (1/1000000))
√(1/1000000) = 1/1000
Thus; √(70 × (1/1000000)) = 1/1000 × √70 = 1/1000 × 8.37 = 0.00837
