A rectangular metal plate is measured to be 7.6cm long and 3.1cm wide, both correct to one decimal place.
What is the upper bound for its length?
Find the upper bound of its area. [write down all the numbers on your calculator display]
Answer:
We know that the rectangular plate has measures of:
length = 7.6 ± 0.05 cm
width = 3.1 ± 0.05 cm
(the error is 0.05cm because we know that both measures are correct to one decimal place)
First, the upper bound of the length is equal to the measure of the length plus the error, this is:
L = 7.6 cm + 0.05 cm = 7.65 cm
The upper bound of the area is the area calculated when we use the upper bound of the length and the upper bound of the widht.
Remember that the area for a rectangle of length L and width W, is:
A = W*L
Then the upper bound of the area is:
A = (7.6cm + 0.05cm)*(3.1cm + 0.05cm) = 10.8 cm^2
Which system of equations does not have the
same solution as the system below?
4x + 3y = 10
-6x - 5y = -16
1) -12x - 9y = -30
12x + 10y = 32
2) 20x + 15y = 50
-18x -15y = -48
3) 24x + 18y = 60
-24x - 20y = -64
4) 40x + 30y = 100
36x + 30y = -96
As per linear equation, except for the option(4), all system of equations have same solution.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, 'A' is a coefficient and 'B' is constant".
Given system equations:
4x + 3y = 10 (equation 1)
-6x - 5y = -16
⇒ (6x + 5y) = 16 (equation 2)
Option. 1: - 12x - 9y = - 30
⇒ - 3(4x + 3y) = - 3
⇒ (4x + 3y) = 10 (equation 3)
Again, 12x + 10y = 32
⇒ 2(6x + 5y) = 16
⇒ (6x + 5y) = 16 (equation 4)
Option. 2: 20x + 15y = 50
⇒ 5(4x + 3y) = 50
⇒ (4x + 3y) = 10 (equation 5)
Again, -18x -15y = -48
⇒ - 3(6x + 5y) = - 48
⇒ (6x + 5y) = 16 (equation 6)
Option. 3: 24x + 18y = 60
⇒ 6(4x + 3y) = 60
⇒ (4x + 3y) = 10 (equation 7)
-24x - 20y = -64
⇒ - 4(6x + 5y) = - 64
⇒ (6x + 5y) = 16 (equation 8)
Option. 4: 40x + 30y = 100
⇒ 10(4x + 3y) = 100
⇒ (4x + 3y) = 10 (equation 9)
Again, 36x + 30y = -96
⇒ 6(6x + 5y) = -96
⇒ (6x + 5y) = -16 (equation 10)
Therefore, except for the option(4), all system of equations have same solution.

A shirt originally priced at $45 was marked down 15%. After a week, the shirt was marked down another 15% off the sale price. What is the percent of change from the original price to the final sale price? Write as decimal percent.
27.76% I believe. infinite decimal.
Answer: 27.75 decrease
Step-by-step explanation:
45 times .85 (100-15(perecent)= 85) is a
a times .85 is b
(b-45)/45 is -0.2775 which is 27.75% which is -27.75
