Brody invested $220 in an account paying an interest rate of 3.6% compounded
annually. Assuming no deposits or withdrawals are made, how much money, to the
nearest ten dollars, would be in the account after 17 years?
Answer:
400
Step-by-step explanation:
Delta
The amount after 17 years is $400
How to determine the amount after 17 years?The given parameters are:
Principal, P = $220Rate, r = 3.6%Time, t = 17 yearsThe interest rate is compounded annually;
So, the amount after t years is:
A = P *(1 + r)^t
This gives
A = 220 * (1 + 3.6%)^17
Evaluate
A = 401.36
To the nearest ten dollars, we have:
A = 400
Hence, the amount after 17 years is $400

Rembrandt framed his masterpiece. The painting by itself is a rectangle with length 20 \text{ cm}20 cm 20, start text, space, c, m, end text and width 16 \text{ cm}16 cm 16, start text, space, c, m, end text. The painting and frame together form a larger rectangle with length 25 \text{ cm}25 cm 25, start text, space, c, m, end text and width 20 \text{ cm}20 cm 20, start text, space, c, m, end text. Find the area of the frame.
Answer:
180cm²
Step-by-step explanation:
Area of the frame = area of the frame+ painting - area of painting.
Area of a rectangle = Length × Width
Area of the painting = 20cm×16cm
Area of the painting = 320cm²
Area of the paint+ frame = 25cm×20cm
Area of the paint+ frame = 500cm²
Area of the frame = 500cm²-320cm²
Area of the frame = 180cm²
Hence the area of the frame is 180cm²

Alan purchased 16 shares of company stock for $390.40. A month later, the total value of his shares fell to $291.20. What is the current price per share if each share costs the same?
A.
$6.20
B.
$18.20
C.
$24.04
D.
$24.40
Answer: $18.20
Step-by-step explanation:
390.40/16 to find the initial costs of the shares. That would be $24.40 per share. However, since the stock has fallen, you would do that same division, but with the new value. 291.20/16, which is $18.20
Answer:
$18.20 per share is the value of each stock currently
Step-by-step explanation:
Take the value the stocks are worth now and divide by the number of shares
291.20/16
$18.20 per share
$18.20 per share is the value of each stock currently
Kyla alternates between walking and jogging on an 11-mile trail. Her walking speed is 4 mi/h, and her jogging speed is 6 mi/h. Kyla takes 2 hours to go from the beginning to the end of the trail. Write and solve an equation to find the distance Kyla walked and the distance she jogged.
Answer:
Kyla walked 2 miles and jogged 9 miles
Step-by-step explanation:
Let the distance Kyla walked be x
and the distance Kyla jogged be y
Since the trail is 11-mile long, then
x + y = 11
Now, from the question,
Her walking speed is 4 mi/h and her jogging speed is 6 mi/h
Let the time spent to walk be t₁ and the time spent to jog be t₂
From
Distance = Speed × Time
Then, the distance walked x is
x = 4 mi/h × t₁
and the distance jogged y is
y = 6 mi/h × t₂
From the question, Kyla takes 2 hours to go from the beginning to the end of the trail, that is
t₁ + t₂ = 2 hours
∴t₁ = 2 - t₂
Since
x + y = 11, then we can write that
(4 mi/h × t₁) + (6 mi/h × t₂) = 11
But t₁ = 2 - t₂
Then,
(4 mi/h × t₁) + (6 mi/h × t₂) = 11; becomes
(4 mi/h × (2 - t₂)) + (6 mi/h × t₂) = 11
8 - 4t₂ + 6t₂ = 11
2t₂ = 11 - 8
2t₂ = 3
t₂ = 3/2
t₂ = 1.5 hours
This is the time spent to jog
Then, from t₁ = 2 - t₂
t₁ = 2 - 1.5
t₁ = 0.5 hour
This is the time spent to walk
Now, For the distance Kyla walked, x
x = 4 mi/h × t₁
x = 4 mi/h × 0.5
x = 2 miles
Hence, she walked 2 miles
and for the distance Kyla jogged, y
y = 6 mi/h × t₂
y = 6 mi/h × 1.5
y = 9 miles
Hence, she jogged 9 miles

Step-by-step explanation:
FIRST, we want to understand every property:
Associative Property: The associative property states that you can add or multiply regardless of how the numbers are grouped so (5 + 4) + 3 = 5 + (4 + 3)
Commutative Property: Commutative is the one that refers to moving stuff around so 3 + 2 = 2 + 3
Additive Inverse Property: This is the number that when added to the original number, equals 0 or it's the opposite of the number so 5 <- is the original number and -5 <- is the additive inverse.
Simplify: Is just to add like terms, and make the equation the simplest.

Step-by-step explanation:
use point slope form y-y1 = m(x-x1)
m = -1/2 because that would be perpendicular
then you plug in the numbers y-6= -1/2(x-4)
then solve for y so i will be in y=mx+b

Answer:
b. x - 2y = 4
Step-by-step explanation:
The two points on the graph are (0, -2) and (4, 0).
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (0 - (-2)) / (4 - 0)
= 2 / 4
= 1 / 2
Find y intercept using anyone of the points above:
y = mx + b
-2 = 1/2(0) + b
b = -2
Use m and b to make equation of line:
y = mx + b
y = 1/2x - 2
Possible answers:
a. 4x - 2y = 4
-2y = -4x + 4
y = 2x - 2
b. x - 2y = 4
-2y = -x + 4
y = 1/2x - 2
c. -2x + 4y = -4
4y = + 2x - 4
y = 1/2x - 1
Only choice b equals the equation of line above.

Let
x = number of tickets
y = cost
For each row, divide the cost over the number of tickets
Row one: y/x = 3/2 = 1.5
Row two: y/x = 6/4 = 1.5
Row three: y/x = 9/6 = 1.5
Row four: y/x = 12/8 = 1.5
Row five: y/x = 15/10 = 1.5
The constant of proportionality is 1.5
This means each ticket costs $1.50

Which graph is the linear function that has a slope of 1/3 and contains the point (- 2, - 4) ?
Answer:
Option 1 (The last one, bottom right)
Step-by-step explanation:
If you start at the origin and go 2 to the left and 4 down, you will reach a point. We can test the slope by using rise over run from one point to another. It goes up 1 and three across which is true in this case.

A popular board game manufacturer was interested in the relationship between the amount of time it takes to play a game and how well that game is rated among board game players. Information was collected on several board games, and was used to obtain the regression equation y = 27.273x + 18.182, where x represents time it takes to play (in hours) and y is the predicted rating of that game (in points). What is the predicted rating of a game that takes 90 minutes to play?
18.182 points
59.0915 points
90 points
2,472.752 points
Answer:
B- 59.015
Step-by-step explanation:
Answer:
The answer is B. I don't know why everyone downvoted the first answer. So here's some fancy work so you know its right.
90 minutes/1 hour = 1.5 hours [one hour = 60 minutes]
(you can only put hours in for x)
27.273(1.5) + 18.182 = 59.0915 (B)
==================
if you're looking for the question "What is the predicted rating of a game that takes 1 hour to play?" the answer is (C), 45.455 points".
