A. Arithmetic; d = 1.5
Step-by-step explanation:
-4, -2.5, -1, 0.5, 2
Looking at the sequence, we can see that the numbers increase. This means our common ration or difference will be positive.
Let's look at common ratios first.
To find the common ratio, divide one term from the term after it.
r = a₂ ÷ a₁
r = -2.5 / -4
Divide.
r = 0.625
To see if this is the common ratio, we want to test this with the other numbers of the sequence.
r = a₃ ÷ a₂
r = -1 / -2.5
r = 0.4
This is not consistent; therefore our sequence is not geometric.
Let's look at common differences next.
To find the common ratio, subtract one term from the term after it.
r = a₂ - a₁
r = -2.5 - (-4)
Simplify.
r = -2.5 + 4
Add.
r = 1.5
To see if this is the common difference, we want to test this with the other numbers of the sequence.
r = a₃ - a₂
r = -1 - (-2.5)
Simplify.
r = -1 + 2.5
r = 1.5
This is consistent; therefore we have found our common difference of this arithmetic sequence.
A. Arithmetic; d = 1.5

Sophia cut a piece of wood that measured 10.2inches but she was supposed to cut 16 inches what is the percent error
Answer: 35.80 %
Step-by-step explanation:
Given
Sophia mistakenly cut 10.2 inches
The actual cut should be 16 inches
[tex]\Rightarrow \% \text{error}=\dfrac{\text{Actual dimension-Faulty dimension}}{\text{Actual dimension}}\times 100\\\\\Rightarrow \% \text{error}=\dfrac{16-10.2}{16.2}\times 100=35.80\%[/tex]
Elena bowls two games on Saturday. Her score in the second game is 30 more than ¾ of her score the first game. Elena's total score for the two games is 478. Write and solve an equation to demonstrate the points scored in her second game.
Answer:
222 = score in 2nd game
Step-by-step explanation:
Let x = score in 1st game
3/4(x) + 30 = score in 2nd game
x + 3/4(x) + 30 = 478 Multiply thru by 4 to eliminate the fraction
4x + 3x + 120 = 1912
7x + 120 = 1912
7x = 1792
x = 256
3/4(x) + 30 = 3/4(256) + 30
= 192 + 30
222 = score in 2nd game
Check: 222 + 256 = 478

The radius of a quarter circle is 3 millimeters. What is the quarter circle's area?
r=3 mm
Answer:
28.3mm
Step-by-step explanation:
3(3)=9(pi)= 28.274...
Answer: 9[tex]\pi[/tex], or more specifically, 28.26, or even more specifically, 28.2643.
Explanation:
To find the area of a circle, you need to do r squared x pi. Since pi repeats randomly infinitely, we are going to simplify it to 3.14. 3 squared or 3 x 3 equals 9. 9 x 3.14 = 28.26. Therefore, the area of the quarter is 28.26. If you want to find the answer without simplifying pi, it is approximately 28.2643. You can also write it as 9[tex]\pi[/tex].

What restrictions are there on the range of the function H(w) below?
H(w)
(5.0,20.00)
A. H(w) s 1
B. H(w) > 0
C. H(w) < 0
D. There are no restrictions on the range of H(w).
Answer:
There are no restrictions on the range of H(w).
The restrictions that are there on the range of the function H(w) is:
Option B: H(w) > 0
How to Identify the Function restrictions?The function, named H(w) is defined by a graph that is a descendant line, that belongs only to the first quadrant.
As w approaches to 0 by the right, the function approaches to + infinity. It never touches the vetical axis, decreases and approaches to 0 when w approaches to infinity. The graph never touches the horizontal - axis.
Then, the function is defined only for positive values of w and H(w) is always positive.
Then, the answer is H(w) > 0, this is the option B

Question: pentagon STUVW is similar to S' T' U' V' W'. angle U=56 degrees, angle U' = 3x-16, and Angle T'=x+46. ST=57, UV=63, S' T'=19 and U' V' =y+4
a. Find x
b. find angle T'
c. Find y
you have to do, a, b, and c
Answer:
Similarity doesn't changes angle measures
∠U = 56°, ∠U' = 3x - 16∠U = ∠U'a) 3x - 16 = 56 ⇒ 3x = 72 ⇒ x = 24°
b) ∠T = x + 46 = 24 + 46 = 70°
c) Scale factor:
k = S'T'/ST = 19/57 = 1/3Find y using known sides and scale factor:
U'V'/UV = 1/3(y + 4)/63 = 1/3y + 4 = 21y = 21 - 4y = 17Thomas earned $38.25 for cleaning the garage. Hewas paid $4.25 per hour. How many hours did it take him to clean the garage? a. 7 hours b. 8 hours c. 9 hours d. 10 hours.
