Lillian thinks that 725 - 4x3 is the same as 3.22. Which statement shows that it is
NOT the same?
Answers
Answer:
The correct option is (c).
Step-by-step explanation:
Lillian thinks that 7x⁵ - 4x³ is the same as 3x².
Option (a) :
7x⁵ - 4x³ = 3x²
It is wrong, as we cannot say directly that they are equal.
Option (b):
7x⁵ - 4x³ ≠ 3x²
It is wrong, as we cannot say directly that they are not equal.
Option (c):
7(2)⁵ - 4(2)³ = 3(2)²
LHS,
7(32) -4(8) = 192
RHS, 12
Here, LHS ≠ RHS
It is correct.
Option (d) :
7(2)⁵ × 4(2)³ = 3(2)²
Here, multiplication is done instead of addition. So, it is wrong.
Hence, the correct option is (c).

R holdA company claims that their new bottle holds 25% more laundry soap. If their original container held 53 fluid ounces of soap, how much does the new containe?
Answers
Answer:
66.25 fluid ounce
Step-by-step explanation:
Given that :
Capacity of original container = 53 fluid ounces
Percentage addition of new container = 25%
Capacity of new container :
Capacity of original container * ( 1 + percentage addition)
53 * ( 1 + 0.25)
53 * (1.25)
= 66.25 fluid ounce
If J is the centroid of cde, de=52, fc=15, he=14, find each missing measure
Answers
Answer:
[tex]DG = 26[/tex]
[tex]GE = 26[/tex]
[tex]DF = 15[/tex]
[tex]CH = 14[/tex]
[tex]CE = 28[/tex]
Step-by-step explanation:
The figure has been attached, to complement the question.
[tex]DE = 52[/tex]
[tex]FC = 15[/tex]
[tex]HE = 14[/tex]
Given that J is the centroid, it means that J divides sides CD, DE and CE into two equal parts respectively and as such the following relationship exist:
[tex]DF = FC[/tex]
[tex]CH = HE[/tex]
[tex]DG = GE[/tex]
Solving (a): DG
If [tex]DG = GE[/tex], then
[tex]DE = DG + GE[/tex]
[tex]DE = DG + DG[/tex]
[tex]DE = 2DG[/tex]
Make DG the subject
[tex]DG = \frac{1}{2}DE[/tex]
Substitute 52 for DE
[tex]DG = \frac{1}{2} * 52[/tex]
[tex]DG = 26[/tex]
Solving (b): GE
If [tex]DG = GE[/tex], then
[tex]GE = DG[/tex]
[tex]GE = 26[/tex]
Solving (c): DF
[tex]DF = FC[/tex]
So:
[tex]DF = 15[/tex]
Solving (d): CH
[tex]CH = HE[/tex]
[tex]CH = 14[/tex]
Solving (e): CE
If [tex]CH = HE[/tex], then
[tex]CE = CH + HE[/tex]
[tex]CE = 14 + 14[/tex]
[tex]CE = 28[/tex]

Jordan is buying plastic plates for a party.The plates usually cost $2.40 per 10 plates,but they are on sale for 30% off usual price.If jordan buys 50 plates,how much will they cost
Answers
30% off means they are paying 70% of the original price.
Sale price = 2.40 x 0.70 = $1.68 for 10 plates
50 plates / 10 = 5
They buy 5 packages of plates.
1.68 x 5 = $8.40
Total price = $8.40
Answer:
Step-by-step explanation:
2.40 X 5 =$12
12 X 0.3=$3.6 off
12-3.6=$8.40
Therefore it'll cost $8.40

Riley buys ice cream and oranges at the store.
She pays a total of $37.15.
She pays a total of $3.62 for the ice cream.
She buys 7 bags of oranges that each cost the same amount.
How much does each bag of oranges cost?
Answers
Answer:
4.79 dollars.
Step-by-step explanation:
7x + 3.62 = 37.15
7x= 37.15-3.62
7x=33.53
x= 33.53/7=4.79 dollars.

A particle moves along the curve y = 5x^2 – 1 in such a way that the y value is decreasing at the rate of 2 units per second. At what rate is x changing when x = 1?
Decreasing one fifth unit/sec
Increasing one fifth unit/sec
Decreasing one tenth unit/sec
Increasing one tenth unit/sec
Answers
Answer:
The correct option is;
Increasing one fifth unit/sec
Step-by-step explanation:
The equation that gives the curve of the particle of the particle is y = 5·x² - 1
The rate of decrease of the y value dy/dt = 2 units per second
We have;
dy/dx = dy/dt × dt/dx
dy/dx = 10·x
dy/dt = 2 units/sec
dt/dx = (dy/dx)/(dy/dt)
dx/dt = dy/dt/(dy/dx) = 2 unit/sec/(10·x)
When x = 1
dx/dt = 2/(10·x) = 2 unit/sec/(10 × 1) = 1/5 unit/sec
dx/dt = 1/5 unit/sec
Therefore, x is increasing one fifth unit/sec.

A polynomial: is an expression consisting of variables and coefficients, with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables
A polynomial never division by a variableA polynomial could be one term, and it could be just a constantLet us solve the question
∵ The polynomial never division by a variable
∵ Answer A and B have a division in variable ⇒ ( [tex]\frac{1}{x^{2}+1 }[/tex] , [tex]\frac{2}{x^{3}}[/tex] )
∴ Answers A and B are not polynomials
∵ The polynomial has integer exponents of variables
∵ Answer D has a fraction exponent of x ⇒ [tex]x^{\frac{2}{3}}[/tex]
∴ Answer D is not a polynomial
∵ [tex]\frac{2}{3}[/tex] x² + x + 1 has a non-negative integer exponent of x
∵ There is no division by x
∴ [tex]\frac{2}{3}[/tex] x² + x + 1 is a polynomial

Y = 4X - 6
Step-by-step explanation:
Slope of linear equation = change in Y / change in X
As Y is changing +4 units, with change in X +1 units. [ -6 - (-2) ] / [ 1 - 0 ]
So, slope = 4
Y = A + BX
Y = A + 4X , as B = slope & A = intercept
Putting values of X & Y (0,-6)
-6 = A + 4 (0)
A = -6
Hence, Equation : Y = 4X - 6

a=7+3
Answers
Answer:
10Step-by-step explanation:
The answer is 10 because 7 + 3 equals 10!
This can be proven by adding 7 + 3 or by subtracting in a certain way.
7 + 3 = ?
7 + 1 = 8
7 + 2 = 9
7 + 3 = 10
You can show more work by subtracting your answer or 10 in this case, which means that you subtract 7 by 10 or 3 by 10, either way is ok.
If you subtract 7 by 10, ( 10 - 7 ) then you get 3
If you subtract 3 by 10, ( 10 - 3 ) then you get 7
If the number you subtracted matches the number that you didn't subtract, then your answer is correct.
