Answer:

d) $b = \sqrt{105}$ ≈ 10.24

Step-by-step explanation:

$a^2+b^2=c^2$

$(4)^2+b^2=(11)^2$

$16+b^2=121$

subtract 16 from both sides

$b^2=105$

$b=\sqrt{105$

b = 10.24695...

b ≈ 10.24

If a=12 and 120% of a is equal to 80% of b then what is a+b

mojhsa [17]

A=12
120% of a =80% of b
120%a = 80%b
120a/100 = 80b/100
Divide through by 100
120a = 80b
Divide through by 80
120a/80 = b
But a=12
120x 12/80 = b
18 = b
b = 18

a+b = 12 + 18 = 30

A meteorologist reports that there is a 30% chance the temperature will fall below freezing tomorrow. On any given day, the bus

sladkih [1.3K]

<h3>Answer: 18%</h3>

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

Explanation:

Convert each percentage to decimal form

30% converts to 0.30
60% converts to 0.60

Then multiply the decimal values

0.30*0.60 = 0.18

That converts to 18%

So there's an 18% chance that both events happen at the same time. In other words, there's an 18% chance of the temperature falling below zero and the bus being late.

The balance in Victor's savings account went from $80 to $120. By what percentage

Nookie1986 [14]

Answer:

50%

Step-by-step explanation:

To find the percent increase, divide the increase by the original value.

The increase is $40.

The original value is $80.

40÷80 = 0.5

0.5 ⇒ 50%

It is a 50% increase.

Which sequences are geometric? Check all that apply.

MatroZZZ [7]

Answer:

The geometric sequences are:

16 , -8 , 4 , -2 , 1 ⇒ 2nd

-15 , -18 , -21.6 , -25.92 , -31.104, ........ ⇒ 3rd

625 , 125 , 25 , 5 , 1 , ........ ⇒ 5th

Step-by-step explanation:

In the geometric sequence there is a constant ratio between each two consecutive terms

Let us find which sequence has a constant ratio between its consecutive terms

-2 , -4 , -6 , -8 , -10

∵ -4 ÷ -2 = 2

∵ -6 ÷ -4 = 1.5

- No constant ratio between the consecutive terms

∴ The sequence is not geometric

16 , -8 , 4 , -2 , 1

∵ -8 ÷ 16 = -0.5

∵ 4 ÷ -8 = -0.5

∵ -2 ÷ 4 = -0.5

∵ 1 ÷ -2 = -0.5

- There is a constant ratio -0.5 between the consecutive terms

∴ The sequence is geometric

-15 , -18 , -21.6 , -25.92 , -31.104, ........

∵ -18 ÷ -15 = 1.2

∵ -21.6 ÷ -18 = 1.2

∵ -25.92 ÷ -21.6 = 1.2

∵ 31.104 ÷ 25.92 = 1.2

- There is a constant ratio 1.2 between the consecutive terms

∴ The sequence is geometric

4 , 10.5 , 17 , 23.5 , 30, ......

∵ 10.5 ÷ 4 = 2.625

∵ 17 ÷ 10.5 = 1.619047619

- No constant ratio between the consecutive terms

∴ The sequence is not geometric

625 , 125 , 25 , 5 , 1 , ........

∵ 125 ÷ 625 = 0.2

∵ 25 ÷ 125 = 0.2

∵ 5 ÷ 25 = 0.2

∵ 1 ÷ 5 = 0.2

- There is a constant ratio 0.2 between the consecutive terms

∴ The sequence is geometric
