I need help on number 28 teacher just gave hw without explanation
Answers
Since we know we can't get "2"
using a multiple of the number [10]
therefore we must check [8]
[8] * 4 = 32
72 - 32 = 40
40 / [10] = 4
[] = $ per job
With this information we could say that:
Destiny made $72 from 8 jobs, 4 being mowing, and another 4 were weeding. Mowing 4 lawns earned her $32 while weeding 4 gardens earned her $40

Answer:
x = 10, y = 20
Step-by-step explanation:
Because this is a geometric sequence, we'll call the rate of change z. Because 40 is 3 terms away from 5, we can write 5 * z * z * z = 5z³ = 40.
z³ = 8 → z = 2
Now, we simply multiply 5 by 2 to get x, which is 10, and then we multiply x by 2 to get 10 * 2 = 20 for y. Hope this helps!
Final answer:
To find the values of x and y in the given geometric progression, we use the concept of a common ratio. By setting up equations based on the definition of a geometric progression, we can solve for x and y. In this case, x is 10 and y is 20.
Explanation:
To find the values of x and y in the given geometric progression, we need to identify the common ratio between the terms. In a geometric progression, each term is obtained by multiplying the previous term by the common ratio. Therefore, we have:
- 5 * r = x
- x * r = y
- y * r = 40
From the first equation, we can substitute x as 5 * r in the second equation:
5 * r * r = y
Then, we substitute y as 5 * r * r in the third equation:
5 * r * r * r = 40
Simplifying the equation, we get:
r^3 = 40/5 = 8
Taking the cube root of both sides:
r = 2
Substituting this value of r back into the equations, we find that x = 10 and y = 20.

the commutative property of multiplication is
note:ab=a times b=a(b)
so a(bc)=(ab)c
first choice: 4.1 times (6.2 times 5.0)=(4.1 times 6.2) times 5.0
this is obviously the right answer A is the answer
B
2.7 times 1=2.7 this is the identity property of multiplicaiton, anything times 1= same thing
C 7.2 times 0=0 this is the 0 property of multiplication
D. 8.5 times 0.4=0.4 times 8.5
this is the equality property
the answer is A

Answer:
The ordered pair (-4,-6) is in the 3rd quadrant
Step-by-step explanation:
If we have an ordered pair (a,b), they would fall in:
- 1st quadrant: if a and b are positive
- 2nd quadrant: if a is negative and b is positive
- 3rd quadrant: if a and b are negative
- 4th quadrant: if a is positive and b is negative
Then, taking into account that -4 and -6 are negative numbers, the ordered pair (-4,-6) belong to the 3rd quadrant
