23$.
In 8 months it will cost 1/3 its original price so you multiple the original price by 1/3.
69.00*1/3
This is the same as dividing by three so just divide 69 by 3 and you get 23.

PLZ I'M BEING TIMED Which equation could have been used to create this table?

Talja [164]

Answer:

y=6x

Step-by-step explanation:

Let us assume the table is the one shown in the attachment.

We can observe the following pattern from the table:

$12=6*2$

$24=6*4$

$36=6*6$

$60=6*10$

$76=6*12$

Hence in general

$y=6*x$

Therefore the equation that could have been used to create this table is

$y=6x$

How to convert base two to base three

sladkih [1.3K]

Consider this example: say we want to convert x = 11 0101 1001₂ to base 3.

The binary expansion of x is

x = 1×2⁹ + 1×2⁸ + 1×2⁶ + 1×2⁴ + 1×2³ + 1×2⁰

which in base 10 reduces to

x = 512 + 256 + 64 + 16 + 8 + 1 = 857

Recall the first several powers of 3:

3⁰ = 1; 3¹ = 3; 3² = 9; 3³ = 27; 3⁴ = 81; 3⁵ = 243; 3⁶ = 729

Now it's a matter of computing quotients and remainders. Pick the largest power of 3 that fits into the target number, then check the remainder and repeat.

• How many times does the 729 go into 857? 1 time, and it leaves a remainder of 128, or

857 = 1×729 + 128 = 1×3⁶ + 128

• How many times does 81 go into 128? Also 1 time, so

128 = 1×81 + 47 = 1×3⁴ + 47

• How many times does 27 go into 47? Also 1 time,

47 = 1×27 + 20 = 1×3³ + 20

• How many times does 9 go into 20? 2 times,

20 = 18 + 2 = 2×9 + 2 = 2×3² + 2

• How many times does 1 go into 2? Also 2 times,

2 = 2 + 1 = 2×1 + 0 = 2×3⁰

So we found

857 = 1×3⁶ + 1×3⁴ + 1×3³ + 2×3² + 2×3⁰

which is the ternary expansion of x,

x = 1 011 202₃

Find the value of x. If necessary, you may learn what the markings on a figure indicate. 74°

marissa [1.9K]

Answer:

x = 61

Step-by-step explanation:

Left hand triangle containing 1 angle of 74

Label the other angle opposite the marked side also as 74

Find the third angle. Call it y.

y + 74 + 74 = 180 Combine like terms

y + 148 = 180 Subtract 148 from both sides.

y = 180 - 148

y = 32

=============

Now work with the triangle on the right.

label the angle making up the right angle = z

32 + z = 90 These two angles are complementary = 90

32 - 32 + z = 90 - 32 Subtract 32 from both sides

z = 58 Use 58 wherever you see z

x + x + z = 180 Substitute

2x + 58 = 180 Subtract 58 from both sides

2x = 122 Divide by 2

x = 61

Don put $4,000 in a savings account with an interest rate of 4% for three years. If the interest is compounded annually, how muc

miskamm [114]

Answer:

$4,499.46

Step-by-step explanation:

We can use the compound interest formula for this problem:

$A=P(1+\frac{r}{n} )^{nt}$

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, lets change 4% into a decimal:

4% -> $\frac{4}{100}$ -> 0.04

Now lets plug the values into the equation as shown below:

$A=4,000(1+\frac{0.04}{1})^{1(3)}$

$A=4,499.46$

Don will have $4,499.46 at the end of the three years.
