Determine if the sequence 0.2 comma 1 comma 5 comma 25 comma... is arithmetic or geometric. Then identify the next term in the sequence.
A
geometric; 125
B
arithmetic; 75
C
arithmetic; 125
D
geometric; 75
Answer:
The answer would be C.
Step-by-step explanation:
0.2 x 5 = 1
1 x 5 =5
5 x 5 = 25
So your next number in the sequence should be 125.
Denise bought a T-shirt at the sale price of $21.08. This represents a 15% decrease in price. What was the original price of the shirt?
Answer:
100% - 15 % = 85 %
So, $21.08 represents the 85% sale price
What number represents the other 15% of the original price?
(21.08 x 15) / 85 = 3. 72
$21.08 + $3.72 = $24.80 which is the original price.

- 2/3+ 1/3 helpppp lol
-0.33333333333
Step-by-step explanation:
23+13 = ?
The two fractions already have like denominators, so just add the numerators:
-23+13=-2 + 13=-13
The result is:
-23+13=–13
Answer:
-2/3 + 1/3 = -1/3
Step-by-step explanation:
using addition to solve a fraction with the same base
step 1: take the denominator of both fractions and clear them from the equation
ex: -2/3 + 1/3 = ? (-2 + 1 = ?)
step 2: solve the new equation -2 + 1 to get your answer of
ex: -2 + 1 = ? (-2 + 1 = -1)
step 3: since both denominators of the fractions have the same number then our answer will also have a denominator of 3 giving us the answer to the problem -2/3 + 1/3 = ? is -1/3
plz give brain if this helps and is correct. thx

7v- 5 ≥ 65 or -3v - 2 ≥ -2
The result if the inequality expressions are v ≥ 10 and v < 0
Given the following inequality expression
7v- 5 ≥ 65 or -3v - 2 ≥ -2
Solve the inequality individually
7v - 5 ≥ 65
Add 5 to both sides
7v - 5 + 5 ≥ 65 +5
7v ≥ 70
v ≥ 70/7
v ≥ 10
For the inequality-3v - 2 ≥ -2
Add 2 to both sides
-3v - 2 + 2≥ -2 + 2
-3v ≥ 0
v < 0
Hence the result if the inequality expressions are v ≥ 10 and v < 0

Answer:
The coordinates of A" are (4, 2)
Step-by-step explanation:
Find the exterior angle
Answer:
x = 128 degrees
Step-by-step explanation:
So we know that a triangle's interior angles should add up to 180 degrees.
We also know that when a triangle has that little square in a corner, that corner is equal to 90 degrees.
With these clues, we can figure out that the last interior angle is equal to:
180 - (38+90) = 52, however this isn't the answer we are looking for.
We also know that a straight line is 180 degrees. Therefore, to find the exterior angle we just subtract the interior angle from 180 degrees:
180 - 52 = 128
x = 128

X= - 3/4
Step-by-step explanation:
P(-2)=-3+4x
Solving for X
-2P=-3+4x
-2(0)=-3+4x
-3=4x

In ΔQRS, q = 9.4 cm, r = 8 cm and ∠S=151°. Find ∠Q, to the nearest 10th of a degree.
9514 1404 393
Answer:
15.7°
Step-by-step explanation:
The law of cosines can be used to find side s:
s² = r² +q² -2rq·cos(S)
s² = 8² +9.4² -2(8)(9.4)·cos(151°) ≈ 283.903
s ≈ 16.849
Then the law of sines can be used to find angle Q.
sin(Q)/q = sin(S)/s
sin(Q) = (q/s)sin(S)
Q = arcsin(q/s·sin(S)) = arcsin(9.4/16.849·sin(151°)) ≈ 15.692°
Angle Q is about 15.7°.
Bus X travels 40 miles per hour for 2 hours; Bus Y travels 60 miles per hour for 1 1/2 hours. What is the difference, in miles, between the number of miles traveled by Bus X and the number of miles traveled by Bus Y?
Answer:
it should be 250m
Step-by-step explanation:
Bus X travels 40m for 2h which gives you 80m and Bus Y travels 60m for 11/2h which gives you 330m so the difference in miles is 250m
