Janet deducted $5 on Monday and another $6 on Tuesday from her savings account. write an expression that represents the change in her account balance after the deductions . How much money did Janet deduct?
Answer: x -11 is the expression and she deducted 11 dollars
Step-by-step explanation:
Let's say x represent the the total amount of money in her savings account.So if 5 and 6 dollars we deducted will have the expression
x - 5 -6 or x -11
In this case Janet deducted 11 dollars.

The base of the Great Pyramid of Giza is about 53,000 square meters, and its height is about 150 meters. What calculation will give us the estimated volume of the Great Pyramid of Giza in cubic meters?
Answer:
The calculation that will give us the estimated volume is the area of the base of the pyramid of Giza in square meters multiplied by the height of the pyramid of Giza in meters divided by 3 i.e A * h/3
Step-by-step explanation:
Here in this question, we are interested in giving the calculation that will give us the estimated volume of the Great pyramid of Giza in cubic meters.
Mathematically, from the first part of the question, the formula for this is obtainable.
We are told that the formula for calculating the volume of a pyramid is A times h/3 where A represents the area of the base of the pyramid and h represents the height of the pyramid.
In equation form;
V = A * h/3
From the question, we are told that the area of the base is 53,000 m^2 while the height is 150 m
Now, plugging these values into the equation above, we have
V = 53,000 * 150/3
V = 53,000 * 50 = 2,650,000 m^3
The estimated volume of the Great Pyramid of Giza in cubic meters is 2,650,000.
Given the following data:
Base of pyramid = 53,000 square meters.Height of pyramid = 150 meters.To calculate the estimated volume of the Great Pyramid of Giza in cubic meters:
Mathematically, the volume of a pyramid is given by the formula:
[tex]Volume = \frac{1}{3} \times base \;area \times height[/tex]
Substituting the given parameters into the formula, we have;
[tex]Volume = \frac{1}{3} \times 53000 \times 150\\\\Volume = 17,666.667 \times 150\\\\Volume = 2,650,000[/tex]
Volume of the Great Pyramid of Giza = 2,650,000 cubic meters

A ball is dropped from the top of a
building. The expression 4.9x2 gives the distance in meters the ball
has fallen after x seconds. Write and simplify an expression that gives the
distance in meters the ball has fallen after x2 seconds. after x3 seconds.
Clear question is;
A ball is dropped from the top of a
building. The expression 4.9x² gives the distance in meters the ball
has fallen after x seconds. Write and simplify an expression that gives the
distance in meters the ball has fallen after x² seconds. after x³ seconds.
Answer:
A) Distance = 4.9x⁴
B) Distance = 4.9x^(6)
Step-by-step explanation:
We are given the expression 4.9x² which is the distance in meters the ball
has fallen after x seconds.
Thus,
A) after x² seconds, we have;
Distance = 4.9(x²)²
Distance = 4.9 * (x²) * (x²)
When we have to multiply 2 same numbers with the same power, the powers add up. Thus, we now have;
Distance = 4.9x⁴
B) after x³ seconds, we have;
Distance = 4.9(x³)²
Distance = 4.9 * (x³) * (x³)
When we have to multiply 2 same numbers with the same power, the powers add up. Thus, we now have;
Distance = 4.9x^(6)
Recycle, reuse, and reduce are referred to as the three R's. Which sequence shows the three R's in order from most to least desirable
Answer:
(1) Reuse; (2) Recycle ; (3) Reduce
Step-by-step explanation:
The ideal sequence would be:
1) Use it again (reuse) if the object still serves its intended purpose/s
2) If not possible to the used again, send it to a recycling plant to extract from it items/parts/substance of utility for other new products
3) if it cannot be reused or recycled, the last option will be to reduce it completely.
solve the simultaneous equations
2p- 3q= 4
3p + 2q= 9
Answer:
q = 6/13, p = 35/13
Step-by-step explanation:
3p + 2q = 9
2p - 3q = 4
_________ (subtract the two equation from each other.)
p + 5q = 5
p = 5 - 5q
2(5 - 5q) - 3q = 4 (substitute value of p into equation)
10 - 10q - 3q = 4
10 - 13q = 4
-13q = -6
q = 6/13
3p + 2(6/13) = 9 (substitute value of q into equation)
3p + 12/13 = 9
3p = 105/13
p = 35/13

Complete the statement below. The expression illustrates the commutative property of multiplication.
Answer:
Option A
Step-by-step explanation:
The expression that completes the blank is A. 11 x w * x 3 = 11 x 3 x w.
What is the cumulative property of multiplication?The commutative property is a mathematical concept that states that the order in which we multiply the factors does not affect the product.
According to the commutative property, a mathematical principle, the product is unaffected by the order in which we multiply the integers.
According to the above, the example of a commutative property is:
11 x w x 3 = 11 x 3 x w
This expression is the one with the commutative property because it has the same factors on both sides of the equation in a different order and that does not affect the result.
Therefore, the correct answer is A.
This question is incomplete because you are missing the options, here are the options:
A. 11 x w x 3 = 11 x 3 x w
B. 11 x w x 3 = 11 x w x 3
C. (11 x w) x 3 = 11 x (w x 3)

An article that is marked $500 was sold for $450 after a discount is given. Calculate the percentage discount given
Answer:
10% discounted
Step-by-step explanation:
500× X = 450
while X is the sale price
so we solve for X
(500X)÷500 = 450 ÷ 500
X = 0.9
then we turn that into percentage
0.9 × 100 = 90%
finding the discount percentage
100% - 90% = 10%

Today you will need to look at the following problem and explain what Susan did incorrectly.
Answer:
see explanation
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 3)² + (y + 4)² = 36 ← is in standard form
with (h, k) = (3, - 4 ) = centre and r = [tex]\sqrt{36}[/tex] = 6
Susan interpreted the values of h and k incorrectly by using the values - 3 and 4 instead of taking the negative of them.
She also divided 36 by 2 , thus omitting the root of 36

Solve the equation for y. y +4x=11;x= -1,0,3
Answer:
y = 15, 11, and -1 when x = -1, 0, and 3 (respectively). Together, we have the points (-1, 15), (0, 11), and (3, -1).
Step-by-step explanation:
Assuming you want to find the values of y for each evaluated x, we will simply plug in the values into the equation.
y + 4x = 11
y = 11 - 4x
For x = -1
y = 11 - 4(-1)
y = 15
For x = 0
y = 11 - 4(0)
y = 11
For x = 3
y = 11 - 4(3)
y = -1
Thus, we have the points, (-1, 15), (0, 11), and (3, -1).

You win the lottery and decide to impress your friends by exhibiting a million-dollar cube of gold. At the time, gold is selling for $1282 per troy ounce, and 1.0000 troy ounce equals 31.1035 g. How tall would your million-dollar cube be?
Answer:
The million dollar cube will be 10.79 cm tall
Step-by-step explanation:
Let the sides of the gold cube representing the tallness of the cube be s
volume of the gold cube V = s³
Then :
[tex]\mathbf{s = \sqrt[3]{V} }[/tex] --- (1)
Similarly; we know that , density ρ = mass m/Volume V
making volume the subject of the formula, then ;
V = m/ρ
Replacing that into (1) above , we have:
[tex]\mathbf{s = \sqrt[3]{\dfrac{m}{\rho}} }[/tex]
Given that:
At the time, gold is selling for $1282 per troy ounce
∴ In a million-dollar cube of gold, the number of troy ounce that can be bought with a million dollar = 1000000/1282 = 780.03 troy ounce
Since 1.0000 troy ounce equals 31.1035 g
∴ 780.03 troy ounce = 780.03 × 31.1035 g
= 24261.66 g
From the tables 12.1 of Gold , the density of Gold is obtained as 19.3 g/cm³
∴
[tex]\mathbf{s = \sqrt[3]{\dfrac{m}{\rho}} }[/tex]
[tex]\mathbf{s = \sqrt[3]{\dfrac{24261.66}{19.3}} }[/tex]
[tex]\mathbf{s = \sqrt[3]{1257.080829} }[/tex]
[tex]\mathbf{s = 10.79 \ cm }}[/tex]
The million dollar cube will be 10.79 cm tall
