The error interval when x is rounded off to 9.8 will be given as 9.75 ≤ x ≤ 9.84.
The number that is rounded off is:
x = 9.8
9.8 can be rounded off for 9.75 to 9.84
So, this means that:
9.75 ≤ x
or 9.84 ≥ x
So, the error interval becomes:
9.75 ≤ x ≤ 9.84
Therefore, we get that, the error interval when x is rounded off to 9.8 will be given as 9.75 ≤ x ≤ 9.84.

Answer:
120
Step-by-step explanation:
deltamath
120 cubic ft is the volume of rectangular prism having a length of 10ft, a height of 3ft, and a width of 4ft
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
A rectangular prism is a 3D figure with 6 rectangular faces.
Given, rectangular prism has a length of 10ft, a height of 3ft, and a width of 4ft.
To find the volume of rectangular prism we have to multiply length, width and height.
Volume =Length×Width×Height
Put the values of length, width and height in the above formula.
=10×4×3
=120 cubic ft
Hence 120 cubic ft is the volume of rectangular prism having a length of 10ft, a height of 3ft, and a width of 4ft

Step-by-step explanation:
Case 1 :
[tex]3x + 2y = 6 \\ 4x + y = 2 \\ 3x = 6 - 2y \\ x = \frac{6 - 2y}{3} = \\ x = 2 - \frac{2y}{3} \\ 4(2 - \frac{2y}{3} ) + y = 2 \\ 8 - \frac{8y}{3} + y = 2 \\ - 1.67y = - 6 \\ [/tex]
[tex]y = 3.59 \\ x = 2 - \frac{2y}{3} \\x = 2 - \frac{2 \times 3.59}{3} \\ \\ x = - 0.39[/tex]
Case 2 :

If you roll a number cube two times, what is the probability of rolling an even on the first roll and a four on the second roll?
Answer:
1/12
Step-by-step explanation:
Probability is a ratio derived as the number of possible outcomes divided by the total outcome.
On a number cube, the even sides are 2, 4 and 6. This means that the possible outcome for rolling an even is 3 while the total outcome is 6. Hence the probability of rolling an even P(E)
= 3/6
The probability of rolling a 4 P(4)
= 1/6 (4 appears on one side)
Hence the probability of rolling an even on the first roll and a four on the second roll
P(En4) = 3/6 * 1/6
= 3/36
= 1/12

Answer:
pretty sure the tree's 20 feet
According to proportion if a tree casts a shadow of 40 feet it;s height is 20 feet.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
We know 1 yard is 3 feet.
Given, The shadow of the tree is 40 feet long. A yardstick placed next to the tree casts a 6-foot shadow and assuming the height of the tree to be x.
∴ x : 40 : : 3 : 6.

solve for the value of w
Answer:
w = 13
Step-by-step explanation:
Right angle: 90°
Write an equation:
(4w + 5)° + 33° = 90°
Solve for w.
(4w + 5)° = 90° - 33°
(4w + 5)° = 57°
You can take away the brackets.
4w + 5 = 57
Isolate w.
4w = 57 - 5
4w = 52
w = 52 ÷ 4
w = 13

Solve the system of equations
2y-3x=-27
5y+3x=6
Answer:
The answer to the first one is y=3/2x-27/2
The answer to the second one is y=-3/5x+6/5
Step-by-step explanation:
1. 2y-3x=-27
first, you want to add '3x' to both sides.
2y=3x-27
then you want to divide '2' from both sides. you do not want to use the 'y' because you want to keep the 'y' on its own side.
y=3/2x-27/2
2. 5y+3x=6
First, you want to subtract '3x' from both sides.
5y=-3x+6
Now, you want to divide '5' from both sides.
y=-3/5x+6/5

First you need to multiply $33.30 by 30 so you can figure out how much she'll save over the next 30 weeks. You will get $999. Then you add $54.50 and $999 together to get 1,053.50.
5. Use the angle addition formula to find the expression for cos (a+b).
Answer:
Step-by-step explanation:
Trigonometric identities are used to show the equality of expressions involving trigonometric functions. These trigonometric functions are the sine, the cosine, and the tangent as well as their respective reciprocals which are cosecant, the secant, and the cotangent,
Some trigonometric identities are:
tanθ = sinθ / cosθ; secθ = 1 / cosθ; cosecθ = 1 / sinθ; cotθ = 1 / tanθ = cosθ / sinθ
The angle addition formula for cos is given as:
cos(α + β) = cosαcosβ - sinαsinβ
Therefore:
cos(a + b) = cosacosb - sinasinb

The population of a town was 25000 in the 2000 census and and 30000 in 2010 census. By what percent did the population increase
Answer: This means that the population increased a 20% between the year 2000 and the year 2010.
Step-by-step explanation:
In this case, we have that 25,000 is the 100%.
Now we want to know which percentage represents 30,000
Let's suppose that the percentage is X.
Then we can have a system of equations:
30,000 = X
25,000 = 100%
To find the value of X, we can take the quotient of these two equations:
30,000/25,000 = X/100%
(30,00/25,000)*100% = X = 120%
Then in the 2000 we had a 100%, and in the 2010 there was a 120%.
The difference is:
120% - 100% = 20%
This means that the population increased a 20% between the year 2000 and the year 2010.
