If you can multiply Ax B, then which of the following statements is true about
multiplying B x A?
You can always multiply BxA.
You can never multiply BXA
You can only multiply B x A if the number of columns of A match the number of rows in B.
O You can only multiply B x A if the number of columns of B match the number of rows of A.
To multiply B and A, the number of columns of B must matc the number of rows of A.
When we can multiply two matrices?
When we multiply two matrices, A and B, we multiply the rows of matrix A by the columns of matrix B.
Now, the number of elements in a row of a matrix, is equal to the number of columns (and the number of elements in a column is equal to the number of rows).
To multiply BxA:
Then, a row on matrix B must have the same number of elements than a column in row A.
Then, to multiply BxA, the number of columns of B must match the number of rows of A, meaning that the correct option is the last one.

The perimeter of the shaded face of this cube is 12 centimeters. What is the volume of the cube in cubic centimeters?
Answer:
1728
Step-by-step explanation: L(length) H(height) W(width)
volume = l x w x h
perimeter= L + W + L + W
perimeter = 12 + 12 + 12 + 12
volume = 12 x 12 x 12 because it' s a cube, and all sides are equal
= 1728

Answer:
Card 3: 53.68 cm, Card 4: 150.72 sq. cm
Step-by-step explanation:
Card 3: First find the circumference, d(pi), 16(3.14)=50.24. Since the circle has 1/4 of it missing, we will divide by 4 then multiply by, 50.24/4=12.56, then multiply by 3 37.68. Lastly, we have to add 16 because of the cutout so 37.68+ 16=53.68
Card 4: Find the area of the circle, r^2(pi), 64(3.14)= 200.96. Then divide by 4 and then multiply by 3, 200.96/4=50.24, 50.24*3=150.72.
At the end of a baseball game, the players were given the choice of having a bottle of water or a box of juice. Of all of the players, 12 chose a bottle of water, which was 3 4 of the total number of players. Write and solve an equation to determine p. the total number of players at the baseball game. Show your work
Answer:
p=48
Explenation:
Total number of players = p
According to given scenario:
p - 12 = 3/4p
By simplifying
Taking terms with p on left and constants on right
p - 3/4p = 12
By taking LCM for left side to make denominators same
4/4*p -3/4p = 12
(4p -3p)/4 = 12
1p/4 = 12
Multiplying both sides by 4 we get
p = 12 * 4
p = 48
So total number of players is 48
what is the inequality shown
Answer:
-4 ≤ x ≤ 3
Step-by-step explanation:
Well, we can see that the endpoints land on -4 and 3 and the numbers between -4 and 3 are included. And since the endpoints -4 and 3 have colored dots, they are included as well. Therefore the inequality is -4 ≤ x ≤ 3.
Answer:
-4 ≤ x ≤ 3
Step-by-step explanation:
Because the circles are closed, we know that the inequaily sign will be either "≤" or "≥", meaning that the dotted points are included. Looking at the number line, we can see that the dots lie on points -4 and 3. Because -4 is less than 3, the sign will be a lesser than sign. The line inbetween includes all numbers between -4 and 3.
So, in conclusion, -4 ≤ x ≤ 3 is the inequality shown.

A group of 50 students at a day camp got to choose an activity to do. 22% of students chose to make a craft, 16% chose to play volleyball, and the rest of the students chose to go on a nature walk. How many students chose to go on a nature walk?
Answer:
31 people
Step-by-step explanation:
Total # of people: 50
22% of 50: 0.22 * 50 = 11 people
16% of 50: 0.16 * 50 = 8 people
11 + 8 = 19 people who didn't go on a nature walk
50 - 19 = 31 people who went on a nature walk

rhombus
Step-by-step explanation:
In geometry, arrows on lines mean that those lines are parallel.
Therefore, as one pair of opposite sides have 1 arrow, and the other pair of opposite sides have 2 arrows, this indicates that each pair of opposite sides are parallel.
Quadrilaterals that have 2 pairs of parallel sides are the rhombus and the parallelogram. A rhombus is a parallelogram that has 4 sides of equal length. As the side lengths of the given shape are equal in length, this quadrilateral is a special type of parallelogram called a rhombus.

pie x r^2 x h = V
Answer:
The volume of the cylinder is 410 ft^3
Step-by-step explanation:
To find the volume, we must know the formula. The formula is, V = π r^2 h. We already know that the diameter is 6ft, so we have to cut that in half to get the radius. 6/2 = 3. The radius is 3ft. Now we can plug in the values.
V = π*3^2*14.5
V = π*9*14.5
V = 409.977841
V = 410.0

For triangle xyz , the measures of angles x,y, and Z are known. Which method should be used to start solving triangle xyz?
law of sines
law of cosines
neither law can be used
both laws can be used
The triangle xyz has three sides and three angles
Neither law can be used to solve the triangle
How to determine the appropriate method?As a general rule, the law of sines states that:
x/sin(X) = y/sin(Y) = z/sin(Z)
As a general rule, the law of cosines states that:
x^2 = y^2 + z^2 - 2yz cos(X)
From the question, we understand that only the angle measures are given.
The sine and the cosine laws above require at least one side length of the triangle in order to solve the triangle
Since the side lengths are not known, then neither of the laws can be used

The directors of a dance show expect many students to participate but don’t yet know how many students will come. The directors need 7 students to work on the technical crew. The rest of the students work on dance routines in groups of 9. For the show to work, they need at least 6 full groups working on dance routines.
The inequality that represents the scenario given above in terms of the number of students is 9x + 7 ≥ 54
What is the Inequality?Inequality is known to be a statement that shows the step or order association either it is greater than, equal to, less than, etc., that exist between two or more numbers in an expression.
Note that 7 students are in the technical crew. Denote the number of students in a group as = x
We take the other students in dance routines in groups of 9 as 9x.
Therefore, we say that the total number of students = 9x + 7
Since 6 full groups are working on dance routines, we then multiply by the student dance groups = 9 x 6 = 54
Therefore, we can state that our inequality as:
9x + 7 ≥ 54
Then you collect like terms:
9x ≥ 54 - 7
9x ≥ 47
x ≥ 47/9
x ≥ 6
So therefore, I will write to directors that the number of students they need in each group should be at least 6 students.

How to determine if a triangle may exist and the existence of given angles
Triangles are geometric figures formed by three line segments and internal angles, whose sum is equal to 180°, which can be three acute angles or an obtuse angle and two acute angles or a right angle and two acute angles. The possibility is determined by applying the law of cosine:
[tex]\cos \theta = -\frac{x^{2}-y^{2}-z^{2}}{2\cdot y\cdot z}[/tex] (1)
The triangle if and only if the cosine of each angle is between -1 and 1 with the following characteristics:
If the cosine of the angle is between 0 and 1, then it is acute.If the cosine of the angle is 0, then it is right.If the cosine of the angle is between 0 and -1, then it is obtuse.Now we proceed to determine the existence of each triangle:
1) cos α = 0.8, cos β = 0.6, cos γ = 0. The triangle exists and is right.
2) cos α ≈ 0.882, cos β ≈ 0.471, cos γ ≈ 0.441. The triangle exists and is acute.
3) cos α ≈ 0.977, cos β ≈ 0.324, cos γ ≈ -0.115. The triangle exists and is obtuse.
4) cos α = 1, cos β = 1, cos γ = -1. The triangle does not exist.
