You purchase a car using a $20,000 loan with a 5% simple interest rate.

1 answer:

6 0

Simple Interest = Cost Price + (Interest Percentage of Cost Price × number of years or months you are paying off)

a) SI = $20 000 + (5% of $20 000 × 4)
SI = $20 000 + ($1000 × 4)
SI = $20 000 + $4000 = $24 000

b) SI = $20 000 + (5% of $20 000 × 2)
SI = $20 000 + ($1000 × 2)
SI = $20 000 + $2000 = $22 000

$24 000 - $22 000 = $2000 that you save!

Answer:

R = 7,34 km

Ф = 63,43° north of east

Step-by-step explanation:

Let´s analyze each movement and find its perpendicular components. Then, we are going to add the components along the x and y axes to get the resultant and finally to calculate its magnitude and direction.

To determine the perpendicular components, we will use right triangles trigonometrics ratios.

Please see images for each displacement in attached file.

Displacement A: 2.50 km and 45° north of west

Ax= AcosФ = 2.50cos45° = 1.77 km (neg. direction)

Ay= AsenФ = 2.50sen45° = 1.77 km (pos. direction)

Displacement B: 4.70 km and 60° south of east

Bx= BcosФ = 4.70cos60° = 2,35 km (pos. direction)

By= BsenФ = 4.70sen60° = 4,07 km (neg. direction)

Displacement C: 1.30 km and 25° south of west

Cx= CcosФ = 1.30cos25° = 1,18 km (neg. direction)

Cy= CsenФ = 1.30sen25° = 0.55 km (neg. direction)

Displacement D: 5.10 km due east (0°)

Dx= DcosФ = 5.10 km (pos. direction)

Dy= DsenФ = 0 km

Displacement E: 1.70 km and 5° east of north

Ex= EsenФ = 1.70sen5° = 0,15 km (pos. direction)

Ey= EcosФ = 1.70cos5° = 1.69 km (pos. direction)

Displacement F: 7.20 km and 55° south of west

Fx= FcosФ = 7.20cos55° = 4.13 km (neg. direction)

Fy= FsenФ = 7.20sen55° = 5.90 km (neg. direction)

Displacement G: 2.80 km and 10° north of east

Gx= GcosФ = 2.80cos10° = 2.76 km (pos. direction)

Gy= GsenФ = 2.80sen10° = 0.49 km (pos. direction)

Now, we add the components along the x- and y- axis to find the components of the resultant (R):

Rx = Ax + Bx + Cx + Dx + Ex + Fx + Gx

Ry = Ay + By + Cy + Dy + Ey + Fy + Gy

Therefore,

Rx= (-1.77)+(2.35)+(-1.18)+(5.10)+(0.15)+(-4.13)+(2.76)

Ry= (1.77)+(-4.07)+(-0.55)+(0)+(1.69)+(-5.90)+(0.49)

Note: minus (-) symbol to negative directions

Rx = 3.28 km

Ry = - 6.57 km

Let´s use the Theorem of Pythagoras to find the magnitud ot the resultant:

$R = \sqrt{Rx^{2} +Ry^{2} }$

$R =\sqrt{(3.28)^{2}+(-6.57)^{2} }$

R = 7,34 km

To find the direction of the resultant:

tanФ = $\frac{Ry}{Rx}$

tanФ = $\frac{6.57}{3.28}$

tanФ = 2.00

Ф = tan-1 (2.00)

Ф = 63,43° north of east

The two Step equations 5k=20

victus00 [196]

Answer: X = 4

Step-by-step explanation: To solve for k in this equation, we want to get k by itself on the left side of the equation.

Since k is being multiplied by 5, to get k by itself, we need to divide by 5 on the left side of the equation. Since we divided by 5 on the left side, we must also divide by 5 on the right side.

On the left side, notice that the 5's cancel out, so we are simply left with z. On the right side, we have 20 divided by 5 which gives us 4.

Now we have X = 4.

Finally, remember to check your answer by substituting a 4 back into the original equation.

So we have 5 (4) = 20 which is a true statement.

This means that our answer, x = 4 is correct.

Please help, I am terrible at math

Zarrin [17]

Answer:

the correct option is D (12 units, 14 units, 10 units)

Step-by-step explanation:

P= 36

2t + 2 + 2t + 4 +2t = 36

combine like terms

6t + 6 = 36

subtract 6 from both sides

6t = 30

30/6 = 5

T = 5 so plug the t in the other equations

2(5) + 2 = 10 + 2 = 12

2(5) + 4 = 10 + 4 = 14

2(5) = 10

To check combine all the numbers above and you would get 36
