Answer:
5.7%
Step-by-step explanation:
The formla for calculating compound interest is expressed as;
A = P(1+r)^t
A is the amount = $430
P is the principal = $220
r is the rate
t is the time = 12 years
Substitute and get r;
430 = 220(1+r)^12
430/220 = (1+r)^12
1.955 = (1+r)^12
1.057 = 1+r
r = 1-1.057
r = 0.057
r = 5.7%
The interest rate is 5.7%

Rita feeds her dog 2/5 pounds of dog food for each meal Rita has just bought 10 punds of dog food. for how many meals will this food last
Answer:
25 meals
Step-by-step explanation:
If Rita feeds her dog 2/5 pounds of dog food for each meal, this means;
2/5 pounds = 1 meal
To get the number of meals she will feed if she buys 10 pounds, we will say;
10 pounds = x meals
Divide both equations to get x;
(2/5)/10 = 1/x
Cross multiply;
2/5 x = 10 * 1
2x/5 = 10
2x = 50
x = 50/2
x = 25
Hence the 10pounds food will last 25 meals

Answer:
9
Step-by-step explanation:
triangles always = 180 degrees
we know there is a 90 degree angle so 180-90=90
we know the other angle is 20 degrees so you do 90-20 which equals 70
now we know that the angle with x equals 70
so then you do 70-16 which equals 54
now just divide 54 by 6 and you get 9
so x=9

How do you solve this, by using substitution?!
Answer:
x = -2, y = -9
Step-by-step explanation:
You can substitute the value of y into y. The first equation shows that y is equal to 4x -1, so we can switch this with the y in the second equation.
y = 2x -5 will become
4x - 1 = 2x - 5
Add 5 to both sides
4x + 4 = 2x
Subtract 4x from both sides
4 = -2x
Divide both sides by -2
-2 = x
Now we plug this number into an equation to find y.
y = 4x - 1 becomes
y = 4(-2) - 1
Simplifying it, we have:
y = -8 - 1
y = -9

Find the measure of angle A
Answer:
21 degrees
Step-by-step explanation:
Triangles have a total angle of 180 degrees.
This makes our equation:
3x+3+4x+135=180
Subtract 135 from both sides and combine like terms
7x + 3 = 45
Subtract 3 from both sides
7x = 42
Divide both sides by 7
x = 6
Plugging the number in:
3x + 3 =
3(6) + 3 =
21
Which number line represents the solution set for the inequality -1/2x>4
Answer: D
Step-by-step explanation: D because if your turn 1/2 into a decimal point it 0.5 (don't forgot to add the negative) and so i then divided -0.5 from x and just got x then you have to do the same for the other side. So i took 4 and divided it by -0.5 and got -8 to the expression would be x is greater then or equal to -8. you plot the dot at -8 and the line goes in front of it because it is lesser or equal to x (remember you reverse the problem if you say it back words so don't get confused), but after my long explanation just pick D

B. 6 baskets worth 3 points each and 7 baskets worth 2 points each
C. 10 baskets worth 3 points each and 1 basket worth 2 points
D. 4 baskets worth 3 points each and 10 baskets worth 2 points each
I'LL GIVE 15 POINTS
Answer:
8, 3 pointers =24 points 4, 2 pointers = 8points 24+8= 34 points
Step-by-step explanation:
Answer:
8 baskets worth 3 points each and 4 baskets worth 2 points each
Step-by-step explanation:
It is 8 baskets worth 3 points each and 4 baskets worth 2 points each because it says Juarez scored twice as many baskets worth 3 points than the baskets worth 2 points. 4 x 2 = 8
-----------------------------------------------------------------------------
6 baskets worth 3 points each and 7 baskets worth 2 points each : wrong because 7 x 2 = 14.
10 baskets worth 3 points each and 1 basket worth 2 points : wrong because 1 x 2 = 2.
4 baskets worth 3 points each and 10 baskets worth 2 points each: wrong because 10 x 2 = 40.

Oliver is starting a running plan to train for a race. In the first week of his running plan, Oliver will run 14 miles. The plan calls for Oliver to increase his weekly milage by 3.5 miles every week. If Oliver sticks to the plan, how many miles would he be expected to run during his 10th week of the training plan?
Answer:
49 miles
Step-by-step explanation:
Let x be equal to the no. of weeks and y be equal to the total amount of miles ran.
Then the equation will be, y = 3.5x + 14
Now to find the amount of miles Oliver ran during the 10th week substitute 10 for x.
So, y = 3.5(10) + 14
y = 35+14
y=49

3)90°
4)90°
5)22°
6)158°
Step-by-step explanation:
Answer:
1. 112º
2. 68º
3. 90º
4. 90º
5. 22º
6. 158º
Step-by-step explanation:
4 - vertical angle to 90º
3 - supplementary to 90º, 180º - 90º = 90º
2 - vertical angle to 68º
1 - supplementary to 68º
5 - all angles in a triangle add up to 180, 180º - 90º - 68º = 22º
6 - supplementary to 22º
how to write y-2=-1/3 (x+6) in standard form and why PLZ HELP
[tex]y-2=-\frac{1}{3}(x+6)\\y=-\frac{1}{3}(x+6)+2[/tex]
Simply move -2 to another side.
[tex]y=-\frac{x}{3}-2+2[/tex]
Distribute -1/3 in (x+6)
[tex]y=-\frac{x}{3}[/tex] ---> Answer
Answer:
x + 3y = 0
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y - 2 = - [tex]\frac{1}{3}[/tex] (x + 6) ← distribute
y - 2 = - [tex]\frac{1}{3}[/tex] x - 2 ( add 2 to both sides )
y = - [tex]\frac{1}{3}[/tex] x ( multiply through by 3 to clear the fraction )
3y = - x ( add x to both sides )
x + 3y = 0 ← in standard form
