According to the rule of 70, how many years will it take an investment that is making 4.5 percent interest to double in size?

1 answer:

8 0

To estimate the number of years for a variable to double, take the number 70 and divide it by the growth rate of the variable. This rule is commonly used with an annual compound interest rate to quickly determine how long it takes to double your money.

So 70÷4.5 = 15.5555556. So the answer is B

How do you solve 1\5 b = 2

Georgia [21]

Answer:

b = 10

Step-by-step explanation:

You can solve for b by dividing both sides by 1/5 because it will remove the 1/5 from the left side of the equation, but what you do to one side you must do to the other side as well.

(1/5b)/ (1/5) = 2/ (1/5)

b = 10

Polygon stuv is reflected over the x axis and then over the y axis to create wxyz . Which of the following sides are congruent ?

JulsSmile [24]

Answer:

ST and WX are congruent ⇒ first answer

Step-by-step explanation:

∵ S = (-5 , -4) , T = (-3 , -1) , U = (-1 , -3) , V = (-2 , -6)

∵ STUV reflected over the x-axis

∴ S' = (-5 , 4) , T' = (-3 , 1) , U' = (-1 , 3) , V' = (-2 , 6)

∵ S'T'U'V' reflected over the y-axis

∴ S" = (5 , 4) , T" = (3 , 1) , U" = (1 , 3) , V" = (2 , 6)

∵ W = (5 , 4) , X = (3 , 1) , Y = (1 , 3) , Z = (2 , 6)

∴ S"T"U"V" is WXYZ

∴ ST and WX are congruent

Answer the question in the pic pls

sweet-ann [11.9K]

The answer is 32. all you have to do is plug in the numbers for what the letters say they indicate so r=4 so you would plug in 4 where the r is and then plus 6 where the b is and then because b and d are right next to each other, that means you need to multiply so plug in 5 for d and then multiply those together, your equation should end up looking like this
√4 + 6(5)

Will a one variable equation always have only one solution

aniked [119]
