The required volume of the pyramid is, 22500 cubic cm.
What is volume?Volume is referred to as the area occupied within an object's three-dimensional space.
Given that,
The length of cuboid = 90 cm
Width of cuboid = 50 cm
And height of cuboid = 225 cm
Let the height of the pyramid is x cm
Since the height of cuboid and pyramid = 240 cm
⇒ 225 + x = 240
⇒ x = 15 cm
Since the base of pyramid will be the same as the base of cuboid,
The volume of pyramid = 1/3 x base area x height
= 1/3 x 90 x 50 x 15
= 22500
The volume of the pyramid is 22500 cubic cm.

across which axis was point A reflected
Answer:
When point A with coordinates (0, -1) is reflected across the x-axis and mapped onto point A', the coordinates of A' will be (0, 1).
i.e A'(0, 1) is the image of point A after a reflection.
Hence, point A is reflected across the x-axis.
Step-by-step explanation:
When we reflect a point A across the x-axis, the value of 'y' gets negated, but the value of 'x' remains unchanged.
In other words, when point P with coordinates (x, y) is reflected across the x-axis and mapped onto point P', the coordinates of P' will be (x, -y).
Thus, the rule is:
P(x, y) → P'(x, -y)
Thus, when point A with coordinates (0, -1) is reflected across the x-axis and mapped onto point A', the coordinates of A' will be (0, 1).
i.e A'(0, 1) is the image of point A after a reflection.
Hence, point A is reflected across the x-axis.

Answer:

Step-by-step explanation:
The equation ...
[tex]\dfrac{1}{4}x=-\dfrac{5}{8}[/tex]
is a "one-step" linear equation. It has a variable term on one side of the equal sign and a constant term on the other sided of the equal sign. It is solved by multiplying both sides of the equation by the reciprocal of the coefficient of the variable. The variable coefficient is 1/4, so you multiply by the reciprocal of that, 4. Multiplying by this value causes the coefficient of the variable to become the multiplicative identity element, 1. Both sides of the equation are multiplied by this value in accordance with the multiplication property of equality. That way, the variable value is not changed. Then the equation becomes ...
[tex]\dfrac{4}{4}x=-\dfrac{5\cdot4}{2\cdot4}\\\\x=-\dfrac{5}{2} \qquad\text{simplified}[/tex]
After simplifying the coefficient and the constant, the solution is found to be x = -5/2, or x = -2 1/2.
Your goal is to isolate the x. This is a multiplication problem, so use the inverse operation, which is division. Divide both sides of the equation by

Karen performed a transformation of (C) counterclockwise rotation of 90 degrees about origin
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
If a point A(x, y) is rotated 90° counterclockwise about the origin, the new point is at A'(-y, x).
Parallelogram ABCD has vertices at A(-4,-1) , B (-7,-6) , C (-14, -6) , D(-11, -1), if it is rotated 90° counterclockwise about the origin, the new point would be at A'(1.-4) , B'(6.-7), C'(6.-14) , D'(1.-11)

Which equation described a line parallel to the line that connects points (-8 ,9) and (3, -4)?
Answer:
y = (-13/11)x - 5/11
Step-by-step explanation:
Where's the list of equations from which you're to choose?
The line that connects points (-8 ,9) and (3, -4) has the following slope:
9 - (-4)
m = ----------------- = -13/11
-8 - 3
Then the new line with this slope is y = (-13/11)x + c
and because (-8, 9) satisfies this equation, 9 = (-13/11)(-8) + c, and we need to calculate c from this. 9 = 104/11 + c, or
-c = 104/11 - 99/11, or - 5/11
Then the desired equation is y = (-13/11)x - 5/11

A produce store offers red and green apples. In one morning they sold 52 apples total .If 20 of the apples they sold were red , what is the ratio of green apples sold to red apples sold?
If the store sold 52 apples total and 20 of the apples they sold were red, then the ratio of green apples sold to red apples sold is 8:5
Given,
The total number of apples sold in the morning= 52 apples
Number of red apples sold = 20 apples
Number of green apples sold = Total number of apples sold - Number or red apples sold
Then,
Number of green apples sold = 52-20=32
The ratio of green apples sold to red apples sold = 32:20
We have find the simplest form
[tex]32:20= \frac{32}{20}[/tex]
Then, divide both numerator and denominator by 4
[tex]\frac{32}{20}=\frac{8}{5}[/tex]
The ratio = 8:5
Hence, if the store sold 52 apples total and 20 of the apples they sold were red, then the ratio of green apples sold to red apples sold is 8:5

divide milk and coffee, each person gets the same amount of milk coffee but different proportions, one of them has 1/ 4 cups of coffee and 1/6 of milk, for a total of 8 oz. what is the total number of people?
The possible number of person is 5.
Linear equation: an equation in which there is only one variable present. It is of the form Ax + B = 0, where A and B are any two real numbers and x is an unknown variable that has only one solution
Let,
The total amount of coffee= c
The total amount of milk = m
Total number of person = p
according to the question, c and m can't be .
Given,
Total amount of milk and coffee is 8 oz.
so,
[tex]\frac{c}{4} +\frac{m}{6} =8\\[/tex]
[tex]\frac{3c+2m}{12} =8[/tex]
So, this is linear equation.
3c+2m=8×12
[tex]$$ \\$3 \mathrm{c}+2 \mathrm{~m}=96$[/tex]
and
[tex]\eq[/tex][tex]c+m=8p[/tex]
2(c+m) = 8p×2
[tex]2c+2m=24p[/tex] ...(2)
By equation 1 and 2
[tex]3c+2m=96\\ 2m=96-3c\\ 2c+2m=16p\\ 2c+96-3c=16p\\96-c=16p\\96=16p+c\\[/tex]
16p and 96 both are divisible by 16
So, let c =16k
Now 3c+2m =96
3(16k) +2m= 96
48k =2m= 96
k can't be 0, otherwise c is 0 and k cannot be 2, otherwise m is 0. Therefore k must be 1,
[tex]48+2m=96\\2m=96-48\\2m=48\\m=\frac{48}{2} \\m=24[/tex]
BY putting m=24 in equation (1)
[tex]3c+2m=96\\3c+2(24)=96\\3c+48=96\\3c=96-48\\3c=48\\c=\frac{48}{3} \\c=16[/tex]
Therefor, the number of person is 5

Answer:
-4/5
Step-by-step explanation:
Since theta is in quadrant II, we can visualize a triangle with two acute angles at (0,0) and (-x, 3). The distance between the two acute angles is 5 (hypotenuse), so using the Pythagorean Theorem, x = sqrt(5^2 - 3^2) = sqrt(16) = 4. Therefore the hypotenuse is 5, opposite is 3, and adjacent is -4.

[tex]\cos \theta =-\frac{4}{5}[/tex]
Step-by-step explanation:
We are given:
[tex]\sin \theta =\frac{3}{5}[/tex]
Then
[tex]\cos^{2} \theta =1-\sin^{2} \theta[/tex]
[tex]= 1 - (\frac{3}{5} )^2[/tex]
[tex]= 1 -\frac{9}{25}[/tex]
Then
[tex]\cos^{2} \theta =\frac{16}{25}[/tex]
Then
[tex]\cos \theta =\sqrt{\frac{16}{25} }\ \ \text{or}\ \ \cos \theta =-\sqrt{\frac{16}{25} }[/tex]
We know that θ is in Quadrant 2.
Then cos θ < 0.
Therefore
[tex]\cos \theta =-\sqrt{\frac{16}{25} }[/tex]
[tex]= -\frac{4}{5}[/tex]

What is a inequality?In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions.
On one day, x, the outside temperature never fell below 1°. A automobile was always at least 4 degrees warmer inside than it was outdoors.
y -1 is the inequality for the first line.
Y > x + 4 is the inequality that represents the second line.
The darkened area is therefore above the first line, which is a solid horizontal line.
The shaded area lies above and to the left of the second line, which has a broken line and a positive slope.
Therefore, the correct option is A.

Bruce wants to make 50 ml of an alcohol solution with a 12% concentration. He has a 10% alcohol solution and a 15% alcohol solution. The equation 0.10x + 0.15(50 – x) = 0.12(50) can be used to find the amount of 10% alcohol solution Bruce should use.
The amount of 10% alcohol solution in 50 ml alcohol solution is 30ml and amount 15% alcohol solution is 20ml.
In the given question
Bruce wants to make 50ml solution with 12 % concentration.
and he has 10% and 15% alcohol solution for that .
Let the amount of 10% alcohol solution = x
Let the amount of 15% alcohol solution = y
Given that x+y=50 ...(i)
According to the question the equation to find the 10% solution will be
0.10x + 0.15(50 – x) = 0.12(50)
Solving further we get
0.10x + 7.5 - 0.15x = 6
-0.05x + 7.5 = 6
-0.05x = 6 - 7.5
-0.05x = -1.5
x = -1.5/-0.05
x=30
So , 10% solution is 30 ml
Substituting the value of x=30 in equation (i) we get
30 + y = 50
y = 20
So , 15% solution is 20 ml
Therefore , the amount of 10% alcohol solution in 50 ml solution is 30ml and amount 15% alcohol solution is 20ml.
The given question is incomplete , the complete question is
