Answer:
6 < x < 8
Step-by-step explanation:
The compound inequality in this instance represent the "and" condition, not the "or" condition.* We might solve it like this.
-47 > 1 -8x > -63 . . . . given
Multiply by -1:
47 < -1 +8x < 63
Add 1:
48 < 8x < 64
Divide by 8:
6 < x < 8
______
* You can tell this is the case by looking at the ends of the given statement:
-47 > -63 . . . . a true statement, so the solution set will be an intersection, not a union.

Mr. Weaver invested part of his $6000 inheritance in an account that earns 4%
simple interest and the other part in an account that earns 7% simple interest.
How much did he invest in each account if the two accounts earned $360 after
the first year?
Answers
Answer:
Mr. Weaver invested $ 2,000 in the 4% simple interest account and $ 4,000 in the 7% simple interest account.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of the inheritance = $ 6,000
Interest rate of the first part = 4% simple
Interest rate of the second part = 7% simple
Interest of the accounts after the first year = $ 360
2. How much did he invest in each account?
For answering the question, we will use the following equation:
x = Amount invested in the first account
6,000 - x = Amount invested in the second account
0.04x + 0.07 * (6,000 - x) = 360
0.04x + 420 - 0.07x = 360
-0.03x = 360 - 420 (Subtracting 420 at both sides)
-0.03x = -60
x = -60/-0.03
x = 2,000 ⇒ 6,000 - x = 4,000
Mr. Weaver invested $ 2,000 in the 4% simple interest account and $ 4,000 in the 7% simple interest account.

If you're good at bearings pls help mee
What is the true bearing of Milton from Binji?
Answers
The leading 0 is important with true bearings. Any true bearing must be three digits.
======================================================
Explanation:
It's not stated, but I'm assuming that Binji and Congo form a flat horizontal line.
B = Binji's location
M = Milton's location
C = Congo's location
The given angles are M = 76 and C = 38. The missing angle is
B = 180-M-C
B = 180-76-38
B = 66
Subtract this from 90 to get 90-66 = 24
The true bearing of Milton from Binji is 024 degrees
In other words, if you are at Binji's location, face directly north, and turn 24 degrees clockwise (turn to the right), then you'll be facing Milton's location.
-------------
Extra info:
In terms of compass notation, the true bearing of 024 degrees converts to N 24 E. This is the same as E 66 N, though convention usually has north used more often (since it's a common reference point with compasses).
N 24 E = start facing north, turn 24 degrees to the east
E 66 N = start facing east, turn 66 degrees to the north

Answer:
6(104) = 624
Step-by-step explanation:
The summation symbol ...
[tex]\sum\limits_{n=1}^{104}{\text{expression}}[/tex]
means that the expression is evaluated for n=1, n=2, n=3, n=4, ... up to n=104 and all of those are added together. Here, the expression being evaluated is "6", which does not depend on n. So, this is simply the sum of 104 instances of 6:
6 +6 +6 +6 ...+6 . . . . 104 terms in the sum
As we know, repeated addition can be accomplished by multiplication:
= 6(104) = 624

Answer:
8(.5)^x
Step-by-step explanation:
This is only broken up into two main parts: the "a" and the "b" of the equation.The "a" is the y-coordinate when x is at 0 and the y-coordinate is 8 there so that fills it in.The "b" is the rate at which for every time x increases by 1, the y decreases by a portion of its current. In this case, every time the x increases by one, the y value cuts in half which means the rate is .5 or one half.Therefore, the answer is 8(.5)^xTwo ants, Andy and Ashley, went to visit their friend.

A certain worker makes $12 per hour for the first 40 hours and $18 for every hour more than 40. Compute her pay for working 45 hours.
Answers
Answer: $570
Step-by-step explanation:
She worked 5 hours more than 40. Thus, for her extra hours she made 18*5, or $90. For her other 40, she made 40*12, or $480. Thus, she made 480+90 dollars, or $570.
Hope it helps <3
Answer:
$570
Step-by-step explanation:
Since she is working 40 hours you need to multiply 12 · 40 first and should get 480
Since there is an extra 5 hours you need to do 18 · 5 = 90
Lastly, you add 480 and 90 and you will get 570
Solve |3x + 9| + 6 = 6 Question 5 options: A) x = 3 B) x = 3 or x = –3 C) No solutions D) x = –3
Answers
Answer:
Hey there!
We have |3x + 9| + 6 = 6. Subtracting 6 from both sides gives us |3x + 9| = 0.
3x+9=0
3x=-9
x=-3
Hope this helps :)
Answer:
-3
Step-by-step explanation:
Subtracting 6 from both sides yields |3x + 9| = 0. For this to be true, 3x + 9 must be 0, and so x must be -3.
A 2-digit number is increased by 36 when the digits are reversed. The sum of the digits is 10. What is the original number?
Answers
====================================================
Work Shown:
T = tens digit of the original number
U = units digit of the original number
U+T = 10 since the digits add to 10. Solve for U to get U = 10-T
10T+U = original number
10U+T = new number where digits are reversed
-----------
new number = (old number) + 36
10U+T = (10T+U)+36
10U+T = 10T+U+36
10(10-T)+T = 10T+10-T+36 ... plug in U = 10-T
100-10T+T = 10T+10-T+36
-9T+100 = 9T+46
100-46 = 9T+9T
54 = 18T
18T = 54
T = 54/18
T = 3 is the tens digit of the original number
U = 10-T
U = 10-3
U = 7 is the units digit of the original number
10T+U = 10*3+7 = 30+7 = 37 is the original number
73 is the reversed number.
73-37 = 36 is the difference, showing that 37 increased by 36 leads to 73. The answer is confirmed.

Answers
Answer:

2. Only forward
Step-by-step explanation:
The reason Statement 1 can be both forward and reverse is because is Bo and Mel are related then it will word forward and backward.
The reason Statement 2 can be only forward is because is the sprinklers are on then the grass is wet will work since it is saying ONLY the sprinklers are on. If it is reverse and the grass is wet if the sprinklers are ONLY on than that is false since if it rains than the grass can also be wet. So there are multiple ways that the grass can be wet hence the answers.

According to the data from the U.S. Census Bureau for 1990-2009, the number of

A(x) = 1.4x – 130.6x² + 1831.3x + 128,141, where x is the number of years after 1990
and A(x) is the number of automobiles in thousands. The number of privately-owned
automobiles in the United States can be modeled by the function
P(x) = -x + 24.9x² – 177.9x + 1709.5, where x is the number of years after 1990 and
P(x) is the number of automobiles in thousands. Estimate the total number of automobiles
owned in 2005.
Answers
Answer: 130875 automobiles
Step-by-step explanation:
To estimate the total number of automobiles owned in 2005, let's first find the number of years
2005 - 1990 = 15 years
Given that the Commercially owned automobiles in the United States can be modeled by the function
A(x) = 1.4x – 130.6x² + 1831.3x + 128,141, where x is the number of years after 1990
and A(x) is the number of automobiles in thousands.
Substitute 15 for x in the function
A(x) = 1.4(15) – 130.6(15)² + 1831.3(15) + 128,141
A(x) = 21 - 29385 + 27469.5 + 128141
A(x) = 126246.5 automobiles
The number of privately-owned automobiles in the United States can be modeled by the function
P(x) = -x + 24.9x² – 177.9x + 1709.5, where x is the number of years after 1990
Substitute 15 for x in the function
P(x) = -(15) + 24.9(15)² – 177.9(15) + 1709.5
P(x) = -15 + 5602.5 - 2668.5 + 1709.5
P(x) = 4628.5 automobiles
The total automobile = A(x) + P(x)
Substitutes for A(x) and P(x)
The total automobile = 126246.5 + 4628.5
= 130875
Therefore, the total number of automobiles owned in 2005 is 130875 automobiles

Answer:

"5 units up" would be "5 added to the current y-value".
"3 units to the left" would be "3 subtracted from the current x-value".
So, the translation rule is:
[tex](x,y)\rightarrow(x-3,y+5)[/tex]
Therefore, Option C should be the correct answer.
Brainilest Appreciated.
The Rule describes the translation is : (x, y) - (x - 3, y + 5)
We have a rectangle on a coordinate plane is translated 5 units up and 3 units to the left.
We have to determine which of the given rules describes the translation.
A point P(3, 3) is translated 10 units up and 4 units to the left. What will be the new coordinates of this point P?The new coordinates of this point P will be - P'( - 1, 13).
According to the question, we have -
Upward translation = 5 units
When the upward translation will take place then, each and every point that lies on that rectangle will have its y - coordinate shifted upwards by +5 units.
Leftward Translation = 3 units
When the leftward translation will take place then, each and every point that lies on that rectangle will have its x - coordinate shifted by - 3 units
to the left.
Hence, rule describes the translation is : (x, y) - (x - 3, y + 5).
