Micheal earns $87 for 15 hours of part time work. How long must he work to earn $135
Answer:
23.28 hours
Step-by-step explanation:
He earns 5.8 per hour of part-time work. You can find this by doing 87/15
Because we now know that he earns 5.8 per hour we can just do 135/5.8 (23.28) < this is rounding to the nearest hundreth

What is the measure of Angle y in this figure?
Two intersection lines. All four angles formed by the intersecting lines are labeled. Clockwise, the angles are labeled 163 degrees, z degrees, y degrees, and x degrees.
Tip: Angles that are across from each other (vertical angles) are congruent.
163°
27°
37°
180°
[tex]\qquad \qquad\huge \underline{\boxed{\sf Answer}}[/tex]
Here, in the given figure. Angle y° forms vertical opposite angle pair with Angle 163°, therefore they have equal values.
that means ~
[tex]\qquad \sf \dashrightarrow \: y \degree = 163 \degree[/tex]
find the value of X. then find the measure of angles B and C
Answer:
x = 20, m∠B = 92°, m∠C = 40°Step-by-step explanation:
Sum of the angles of any triangle is 180°:
m∠A + m∠B + m∠C = 180°Substitute the given values and solve for x:
48 + 6x - 28 + 2x = 1808x + 20 = 1808x = 160x = 20Find the missing angles:
m∠B = 6*20 - 28 = 120 - 28 = 92°m∠C = 2*20 = 40°[Sum of the angles of any triangle is 180°]
↦m∠A + m∠B + m∠C = 180°
The given values and solve for x :
[tex]↦48 + 6x - 28 + 2x = 180°[/tex]
[tex]↦8x + 20 = 180°[/tex]
[tex]↦8x = 160°[/tex]
[tex]↦x = 20°[/tex]
Lets , Find the missing angles:
[tex]↦ m∠B = 6×20 -28 = 120-28 = 92°[/tex]
[tex]↦ m∠C = 2×20 = 40°[/tex]

I am stuck on this question it was can you add 4+2x to get 6x
Answer:
No you can't.
Step-by-step explanation:
4 is an integer, and 2x isn't so you can't add them together. If 4 was 4x or 2x was 2, then you'd get 6, but you can't add them. Hope this helps :)

Plot and connect the points A(1,-5), B(-4,-3), C(3,-3), and find the area of the triangle it forms.
Answer:
7 square units
Step-by-step explanation:
Two of the points are on the horizontal line y = -3, so it is convenient to call that the "base" of the triangle. The length of the base is the difference in the x-coordinates of its end points:
b = 3 -(-4) = 7
The height is measured perpendicular to the base, so is the vertical distance from the line y=-3 to the third point. That distance is the difference between -3 and the y-coordinate of point A:
-3 -(-5) = 2
The triangle has a base of length 7 and a height of 2. Its area is ...
A = 1/2bh
A = 1/2(7)(2) = 7 . . . . square units

Based on the information in the table, which of the following is an example of independent events.
O P(librarian and chooses book)
OP(librarian and chooses movie)
OP(teacher and chooses play)
O Pteacher and chooses book)
P(teacher and chooses play) is an example of independent events.
What is Independent events?
Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B.
According to questions, the activity preference of teachers and librarians
are:
For Teachers:
Movies 3
Books 4
Plays 2
For Librarians:
Movies 12
Books 9
Plays 15
Since, Teacher and Plays both are independent events, they are not related to each other.
So, we can conclude that P(teacher and chooses play) is an example of independent events.

O 2R3+-R3 > R3

The matrix shown represents its elements in rows and columns
The operation performed by the student is R3 -> 2R2 + R3.
How to determine the matrix operation?The matrix is given as:
[tex]\left[\begin{array}{cccc}-4&1&2&4&0&-1&3&1&3&2&4&5\end{array}\right][/tex]
Multiply the elements on the second row (Row 2) by 2.
So, we have:
2R2 = 0 -2 6 2
Add these elements to the third row (Row 3).
So, we have:
2R2 + R3 = 3 0 10 7
Replace the row 3 by the above elements.
i.e.
R3 -> 2R2 + R3.
So, we have:
[tex]\left[\begin{array}{cccc}-4&1&2&4&0&-1&3&1&3&0&10&7\end{array}\right][/tex]
Hence, the operation performed by the student is R3 -> 2R2 + R3.

Hanna's situation?
a.) 4m + 16 > 40
b.) 4m + 16 < 40
c.) 16m + 4 > 40
d.) 16m + 4 < 40
Answer:4m+16<40
Step-by-step explanation:
m=magazines
She's planning on buying a number of magazines (m) with a cost of $4 so it would be "4m".
She's planning on buying a book for $16 also so
4m+16
She wants to have a price all under 40 so
4m+16 < 40
