9a: 1/5. She takes a 1/5 and puts it in each so your fraction is 1/5
9b: $105. 525 / 5 = 105
10: Option 1. He gains more money this way.
In option 1 if he gets his allowence for 4 weeks, he would make $15 (1+2+4+8).
But in option 2 he would only make $4 because the square of 1 is 1 (1+1+1+1)
Hope that helps and hope I did that correctly
Total amount = $525
Split by a fraction, divide by 5 and then again divide by 5:
525*1/5*1/5 = 525*1/25 = 21a) The fraction = 1/25b) The amount = $21#10Option 1 results in sequence:
1, 1*2=2, 2*2=4, 4*2=8, etcOption 2 results in sequence:
1, 1² = 1, 1² = 1, 1² = 1, etc.It's obvious that option 1 is a better choice.

then climbed at 0.4 meters per second for 5 seconds.
What was the average rate of change in altitude per second?
Answer:
Step-by-step explanation:
we will use 0,8 in 10 seconds as thats the easiest.
for 10 to become 1 we move the decimel once to the right, 10/10
same will happen to 0.8,
10/10=1
0.8/10=0.08
The hot air-ballon climbs 0,08 meters per second

The length of a rectangle is 4ft longer than it’s width. If the perimeter of the rectangle is 68ft, find it’s length and width.
Answer:
Represent the length and width by L and W. Then L = W + 4.
Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).
Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.
The dimensions of the rectangle are 15 by 19 feet.

Answer:
1.) x = -5
y = -4
Point to graph: (-5, -4)
2.) x = 0
y = -6
Point to graph: (0, -6)
3.) x = 5
y = 8
Point to graph: (5, 8)
Step-by-step explanation:
Substitute x for the given value, then find y.
1.) -2(-5)-5y = 30
10-5y = 30
-5y = 20
y = -4
2.) -2(0)-5y = 30
-5y = 30
y = -6
3.) -2(5)-5y = 30
-10-5y = 30
-5y = 40
y = -8

Answer:
24 cars
Step-by-step explanation:
By using 11 cars and AED 79.75, you can find out the cost of washing 1 car.
(AED 79.75)/(11 cars) = AED 7.25 / car
Now we divide AED 174 by AED 7.25/car to find the number of cars.
(AED 174) / [(AED 7.25)/car] = (174/7.25) cars = 24 cars
Answer: 24 cars
Write the equation of a line that passes the point (-6,9)and is perpendicular to a line that passes through the points (-2,1) and (6,7).
Answer:
y = 4/3x + 1.
Step-by-step explanation:
The equation of the lines passing through (2,1) and (6,7) is:
y - 7 = (7-1)/(6- -2)(x - 6)
y - 7 = 6/8(x - 6)
y = 3/4(x - 6) + 7
y = 3/4x + 5/2.
So the line perpendicular to it has slope -1/3/4 = -4/3:
y - 9 = -4/3(x + 6)
y = -4/3 x - 8 + 9
y = 4/3x + 1.

Answer: Just bought 21 pounds of coffee A
Step-by-step explanation:
We know that she consumed twice as many pounds of Type B coffee as type A.Then let the total number of cafe feet A=x ; then the number of cafe feet B=2x . We also know that the total number of feet cost $336And the fact that one pound of coffee A costs $ 4.1 ; and one pound of coffee B costs $ 5.95 Then :[tex]\large \boldsymbol {} 2x\cdot 5,95 +x\cdot 4,1 =336 \\\\ 11,9x+4,1x=336 \\\\ 16x=336 \\\\ \boxed{x=21}[/tex]Which tool should Darla and Rob use to measure the force that pulls the car down the ramp?

Jenny & Natasha are working on a problem together: Solve x/3 + 8 = −2. Natasha thinks the first step is to multiply by 3. Jenny explains that this is not the most efficient way to solve. Explain who is correct & justify your reasoning.
The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method
The given equation is [tex]\frac{x}{3} + 8 = -2[/tex]
Solving the equation using Natasha's method
the fist step is to multiply by 2
x + 24 = - 6
The second step is to combine and add similar terms
x = -24 - 6
x = -30
Second method of solving the equation
The equation the friends are trying to solve is [tex]\frac{x}{3} + 8 = -2[/tex]
The first step is to combine similar terms
[tex]\frac{x}{3}[/tex] = - 8 - 2
The second step is to add similar terms together
[tex]\frac{x}{3}[/tex] = - 10
The third step is to multiply both sides of the equation by 3
x = (-10 x 3)
x = -30

Answer:
Read below
Step-by-step explanation:
For the first row, the inequality is x ≤ -5.
For the second row, the inequality is x < -5.
For the last row, the inequality matching the graph is x ≥ -5.
A trick to remember the sign is if the point on the graph is empty, then the sign would be either < or >, and if it's filled, it would be ≤ or ≥.
Also, x is less is on the left (negative) and x is more is on the right (positive).

Step-by-step explanation:
60*3=180
Hey there! The answer is:
180 minutes
Explanation:
There are 60 minutes in 1 hour. We know Colin typed his research paper for 3 hours. This means we can multiply 60 minutes by 3 hours and that will give us the number of minutes he spent researching his paper.
60 x 3 = 180
This means Colin typed his research paper for 180 minutes. I hope this answer helped you out, have an amazing day :)
