Answer:
18
Step-by-step explanation:
So lets go voer what we know:
There are 6 pieces of ribbon.
Each piece of ribbon is 1 yard long.
We need 1/3 of each ribbon(1/3 yard).
To find this, lets take our 6 pieces of ribbbon, and break them into 3 seperate pieces.
This is because we need ribbons that are 1/3 of a yard. 3 ribbons would make up a single yard.
So:
The 6 yards of ribbon x 3 ribbons that make up 1 yard
6*3
=
18

What is the vertex of the function f(x) = x2 + 12x?
O (-6, -36)
O (-6,0)
O (60)
O (6,-36)
Answer:
es la tercera amiga yo pienso
The vertex of the function f(x) = x² + 12x is,
⇒ Vertex = (- 6, - 36)
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The function is,
⇒ f (x) = x² + 12x
Now, We can change the function into the form,
f (x) = (x - h)² + k
Where, (h, k) is vertex.
Here, The function is,
⇒ f (x) = x² + 12x
⇒ f (x) = x² + 12x + 36 - 36
⇒ f (x) = (x + 6)² - 36
⇒ f (x) = (x - (- 6))² + (- 36)
Hence, By comparing,
Vertex = (h, k) = (- 6, - 36)
Thus, The vertex of the function f(x) = x² + 12x is,
⇒ Vertex = (- 6, - 36)

A coach purchases 47 hats for his players and their families at a total cost of $302. The cost of a small hat is $5.50. A medium hat costs $6.00. A large hat costs $7.00. He purchases three times as many medium hats as small hats. Using matrices, how many large hats did the coach purchase?
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of small hat purchased, y represent the number of medium hat purchased and z represent the number of large hat purchased.
Since a total of 47 hats where purchased, hence:
x + y + z = 47 (1)
Also, he spent a total of $302, hence:
5.5x + 6y + 7z = 302 (2)
He purchases three times as many medium hats as small hats, hence:
y = 3x
-x + 3y = 0 (3)
Represent equations 1, 2 and 3 in matrix form gives:
[tex]\left[\begin{array}{ccc}1&1&1\\5.5&6&7\\-3&1&0\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}47\\302\\0\end{array}\right] \\\\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}1&1&1\\5.5&6&7\\-3&1&0\end{array}\right] ^{-1} \left[\begin{array}{c}47\\302\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}6\\18\\23\end{array}\right][/tex]
Therefore he purchases 6 small hats, 18 medium hats and 23 large hats
Answer:
Let x represent the number of small hat purchased, y represent the number of medium hat purchased and z represent the number of large hat purchased.
Since a total of 47 hats where purchased, hence:
x + y + z = 47 (1)
Also, he spent a total of $302, hence:

He purchases three times as many medium hats as small hats, hence:

Therefore he purchases 6 small hats, 18 medium hats and 23 large hats

You randomly draw a marble from a bag, record is color, and then replace it. You draw a blue marble 11 out of 50 times. What is the experimental probability that the nes marble will be blue? Write your answer as a fraction, de mal, or percent. The experimental probabilty that the next marble will be blue is
Explanation:
This may seem like a trick question, but it's not. Your teacher simply wants to know how many times you got blue out of the number of times total. The numerator is the number of blue. The denominator is the number of total tries. The fraction 11/50 cannot be reduced because 11 and 50 share no common factors other than 1.

She drinks 70 ounces of water each day. Before her ride she drinks 14 ounces. What percent of water does she drink. Find an equivalent amount of water to 100 ounces.
Answer:
Percentage of water consumed = 20 %
Equivalent amount of water to 100 ounces = 20 ounces
Step-by-step explanation:
The total amount of water consumed by her daily = 70 ounces
The total amount of water consumed by her before ride = 14 ounces
Percentage of water consumed = total amount of water consumed by her before ride /total amount of water consumed by her daily * 100
Substituting the given values we get

Step-by-step explanation:
By definition, similar triangles have equal angles and proportional corresponding side lengths. Thus, A, B, and D are all mutually exclusive, leaving C the only possible answer.

Answer:
r = 9 units
Step-by-step explanation:
[tex] In\: \odot O, [/tex] QP is tangent at point P and OP is radius.
[tex] \therefore OP\perp QP[/tex]
[tex] \therefore m\angle OPQ = 90\degree [/tex]
So, [tex] \triangle OPQ[/tex] is a right angled triangle. Hence, OQ will be its HYPOTENUSE such that OQ = r + 32
Now, by Pythagoras theorem:
[tex] OQ^2 = OP^2 + PQ^2 [/tex]
[tex] \therefore (r + 32)^2 = r^2 + (40)^2 [/tex]
[tex] \therefore\cancel {r^2} + 64r + 1024 = \cancel {r^2} + 1600 [/tex]
[tex] \therefore 64r = 1600-1024 [/tex]
[tex] \therefore 64r = 576 [/tex]
[tex] \therefore r = \frac{576}{64}[/tex]

△WXY is a right triangle, and △WZY is an isosceles triangle where WY¯¯¯¯¯¯≅ZY¯¯¯¯¯. Which is the measure of ∠XYZ?
Answer:
61 degrees
Step-by-step explanation:
TRUST ME I JUST DID THE IMAGINE MATH LESSON. !!!!
The measure of ∠XYZ in right triangle is 90 degrees.
What is an isosceles right angled triangle?It has two equal sides, and those two equal sides make 90 degrees (right angle) internally. An isosceles triangle has two of its side length of same measure.
Let the considered isosceles triangle has two same lengthed sides of 'a' units.
Let its third side be of 'b' units.
Then, if we drop a perpendicular from the vertex joining similar sides to the opposite side, the opposite side is cut in half, each of length b/2 units.
We are given that;
A right triangle △WXY and △WZY
Now,
Let's label ∠WZY as α, so we have:
∠WZY = α
∠WYZ = α
Since the sum of the angles in a triangle is 180 degrees, we can find ∠WYX of △WXY:
∠WYX = 90 - ∠WXY
Now, we can use the fact that ∠WXY and ∠XYZ are complementary angles of a right triangle, so:
∠WXY + ∠XYZ = 90
Substituting ∠WYX for ∠WXY, we get:
∠WYX + ∠XYZ = 90
90 - ∠WXY + ∠XYZ = 90
∠XYZ = ∠WXY
Therefore, we can conclude that ∠XYZ is equal to ∠WYX, which is the angle opposite to the hypotenuse in a right triangle. So, we have:
∠XYZ = 90 degrees
Hence, in the given right triangle answer will be 90 degrees.

AB is tangent to circle O if AO = 30 and bc = 48 what is AB
Answer: 72
Step-by-step explanation:
30+48=78
√78^2-30^2=
√5184=
72
If AO = 30, BC = 48 then, AB = 72.
What is tangent?"Tangent to a circle is the line that touches the circle at only one point."
"A tangent to a circle is always perpendicular to the radius of a circle."
For given question,
AB is tangent to circle.
Also, AO = 30, BC = 48
From figure, we can observe that,
AO = CO .......................(radius of circle)
⇒OC = 48
Also,
OB = OC + BC
⇒ OB = 30 + 48
⇒ OB = 78
We know, a tangent to a circle is always perpendicular to the radius of a circle.
⇒ AB ⊥ AO
This means, ΔAOB is right triangle.
Using Pythagoras theorem to right triangle AOB,
⇒ [tex](OB)^{2} = (AO)^{2} + (AB)^{2}[/tex]
⇒ [tex](AB)^2 = (OB)^{2} - (AO)^{2}[/tex]
⇒ [tex](AB)^2=(78)^2-(30)^2[/tex]
⇒ [tex](AB)^2=5184[/tex]
⇒ [tex]AB=\sqrt{5184}[/tex]
⇒ [tex]\bold{AB=72}[/tex]
