Answer:
A bag of apples cost $3.2 and orange $1.6
Let oranges be o and apples be a
making equations:o + 3a ↬ 11.22o + 4a ↬ 16making o the subject
o = 11.2 - 3ao = (16-4a)/2solve them simultaneously
11.2 - 3a = (16-4a)/2
2(11.2 - 3a) = 16 -4a
22.4 -6a = 16 -4a
2a = 6.4
a = 3.2
➜ Therefore a bag of apples cost $3.2
Find the cost of oranges:
o = 11.2 - 3a
o = 11.2 -3(3.2)
o = 1.6
➜ Therefore a bag of oranges cost $1.6

Set of Data (Prioritized):
15, 16, 17, 18, 24, 28, 32, 32, 68, 71
To find the median:
Count how many times each number occurs. The number that occurs the most is the mode, and that number is 32.
Therefore, the mode is equal to 32.

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.

Answer:
50.24
Step-by-step explanation:
8÷2 is the radius. 3.14×4^2=50.24 m^2
^= where the exponent is supposed to go
Find the area and the circumference of a circle with diameter 8 m .
Given : -Diameter of circle = 8 mTo Find : -Area of circleCircumference of circleFormula Used :1)

2)
[tex] \pink{\boxed{\sf{Circumference of circle = 2\pi r}}}[/tex]
So Starting Our Solution :We know that radius of circle is always halves of its diameter . So radius of circle :
8/24 m1) Finding area :
πr²3.14 × 4 × 43.14 × 1650.24 m²Therefore, area of circle is 50.24 m² .
2) Finding circumference :
2πr2 × 3.14 × 46.28 × 425.12 mTherefore, circumference of circle is 25.02 m

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

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]

Hanna must spend no more than $40 at the bookstore. She is planning on buying
a book for $16 and some magazines, m, for $4 each. Which inequality represents
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

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
