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.

Answers

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

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.

Answers

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

Answers

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.

A function assigns the value of each element of one set to the other specific element of another set. The value of f(8) is 5.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

The function that is given is mentioned below. Now, the value of the function can be found as shown below.

A.) f(-10)=?

When the value x is -10, it will lie in the first category of the function, therefore, the function for this value of x will be,

[tex]f(x) = 2x+1\\\\f(-10) = 2(-10)+1\\\\f(-10) = -20+1 = -19[/tex]

B.) f(2) = ?

When the value x is 2, it will lie in the second category of the function, therefore, the function for this value of x will be,

[tex]f(x) = x^2\\\\f(2) = 2^2 = 4[/tex]

C.) f(-5)=?

When the value x is -5, it will lie in the first category of the function, therefore, the function for this value of x will be,

[tex]f(x) = 2x+1\\\\f(-5) = 2(-5)+1\\\\f(-5) = -10+1 = -9[/tex]

D.) f(-1)=?

When the value x is -1, it will lie in the second category of the function, therefore, the function for this value of x will be,

[tex]f(x) = x^2\\\\f(-1) = (-1)^2 = 1[/tex]

E.) f(8)=?

When the value x is 8, it will lie in the third category of the function, therefore, the function for this value of x will be,

[tex]f(x) = x-3\\\\f(8) = 8-3 = 5[/tex]

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?

Answers

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 years

The 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

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

Answers

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
