Answer: The value of the car in 2021 will be $11,276.31.

Step-by-step explanation:

If r is the depreciation rate and P is the initiial amount , then the amount after t years is given by:-

[tex]A=P(1-\dfrac{r}{100})^t[/tex]

Given: P=21000, r=8.5%  , t= 2021-2014= 7

Plug all the values in the formula, we get

[tex]A= 21000(1-\dfrac{8.5}{100})^7\\\\\Rightarrow\ A=21000(1-0.085)^7\\\\\Rightarrow\ A= 21000(0.915)^7\\\\\Rightarrow\ A= 21000(0.5369670)\approx11276.31[/tex]

The value of the car in 2021 will be $11,276.31.

Answer:

x ≈ 13.5

Step-by-step explanation:

Using the sine rule in the triangle, then

[tex]\frac{sin34}{x}[/tex] = [tex]\frac{sin27}{11}[/tex] ( cross- multiply )

x × sin27° = 11 × sin34° ( divide both sides by sin27° )

x = [tex]\frac{11sin34}{sin27}[/tex] ≈ 13.5 ( to the nearest tenth )

Answer:

16 + 104 = 120 square inches

Step-by-step explanation:

13 x 8 = 104

17 - 13 = 4

4 x 8 =32

32 divided by 2 is 16

so 16 +104 = 120

Answer:

Starting time = 11:43 pm last night

Step-by-step explanation:

The time that her train started from the station is as follows

Given that

Grandparents reached the place at 9:20AM

The travelled time is 9 hours and 37 mins i.e. 9:37 hours

Starting time = Reached time - journey time

Starting time = 9:20 am - 9:37 hrs

= 11:43 pm last night

Answer:

-3/5

Step-by-step explanation:

Slope is calculated with the formula m=(y_2 - y_1)/(x_2-x_2). The starting point I put as (0,0) and the finish is (5,-3). I used one city block is equal to one. Thus 3 blocks south(y-axis), is -3 and 5 east(x-axis) is 5. So plug into the equation with y_2 as -3 and x_2 as 5 then y_1 and x_1 both as zero. Thus slope=m= -3/5.

Answer:

a=# of apples

3/8(a)=# of oranges

p=# of pears

3/4(p)=# of oranges

(3/8)a=(3/4)p

(3/8)/(3/4)=p/a

(3/8)(6/8)=p/a

3/6=p/a

1/2=p/a

the ratios of pears to apples is 1 to 2

for every 1 pear there are 2 apples

if there are 4 pears there are 8 apples

there are 8 apples

(3/8)(8)=3 oranges

there are 4 pears

(3/4)(4)=3 oranges again

8 apples, 3 oranges, 4 pears

15 pieces of fruit and 3 are oranges

ratio is 3/15=1/5

            [tex]\bold{k=\pm\dfrac{\sqrt6}{2}\approx\pm1.22}[/tex]

Step-by-step explanation:

[tex]2k^2-3=0\\\\a=2\,,\ \ b=0\,,\ \ c=-3\\\\k=\dfrac{-0\pm\sqrt{0^2-4\cdot2\cdot(-3)}}{2\cdot2}=\dfrac{\pm\sqrt{24}}{2\cdot2}=\dfrac{\pm2\sqrt{6}}{2\cdot2}=\pm\dfrac{\sqrt6}{2}\approx\pm1.22[/tex]

[tex] \sf \dfrac{24}{2} = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \:\dfrac{24}{2} = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \: \cancel{\dfrac{24}{2}} = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \:12 = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \:12 \times 7 = t[/tex]

[tex] \sf \dashrightarrow \:84 = t[/tex]

The area for the square is given, and it is 36. To simply find the length of each side, all you have to do is take the area and square root it. The square root of 36 ( ask yourself what number times itself is equal to 36? To get your answer or input it in the calculator. ) is 6. So, the answer is 6 and each side of the quilt is a length of 6.

Answer:

48 °

Step-by-step explanation:

The following data were obtained from the question:

Adjacent = 12 cm

Hypothenus = 18 cm

Angle R =?

We can obtain angle R by using cosine ratio. This can be obtained as follow:

Cos R = Adjacent / Hypothenus

Cos R = 12 / 18

Cos R = 0.6667

Take the inverse of Cos

R = Cos¯¹ 0.6667

R = 48 °

Thus, <QRP = 48 °
