Whats 13% of 80
plz answer correctly

Answers

Answer 1

Answer: Start by dividing 13% by 100 because we need to make it into a decimal
13/100=0.13
of=multiply
So from here we simply multiply:
0.13*80=10.4
So our final answer would be: 10.4

Answer 2

Answer: We have an equation: ?/80= 13/100

Cross multiply:
100*?= 13*80
⇒ ?= 13*80/100= 10.4

13% of 80 is 10.4~

Please help! I am unsure how to solve.The density D of water is 3.12*10^-2 tons per cubic foot. The volume V in a lake is 4.266*10^14 cubic feet. Use the formula D=M/V to find the mass M (in tons) of the water in the lake using scientific notation.

Answers

Mass of water in the lake is 1.3309 × 10¹³ tons.

Step-by-step explanation:

Density is defined as mass divided by volume.

Given:

Density of water, d = 3.12 × 10⁻² tons / cubic foot

Volume of the lake, v = 4.266 × 10¹⁴ cubic feet

Mass of the water in tons, m = ?

Formula to be used:

$$d = (m)/(V)$

Mass = Density × Volume

=3.12 × 10⁻² tons / cubic foot × 4.266 × 10¹⁴ cubic feet

= 1.3309 × 10¹³ tons of water

A survey of people regarding their favorite flavor of ice cream shows 60% prefer chocolate ice cream, 30% prefer vanilla, and 10% prefer other flavors. If 86 people were surveyed in total, how many prefer vanilla? Round to a whole number.

Answers

26 people would prefer vanilla out of 86 people

Step-by-step explanation:

The percentage is calculated by multiplying the quantity with rate of percentage

Given

Total people surveyed = 86

We have to calculate the number of people who prefer vanilla

The percentage of people who prefer vanilla = 30%

So,

$No.\ of\ people\ who\ prefer\ vanilla = 30\%\ of\ 86\n= 0.30 * 86\n= 25.8$

Rounding off to the nearest whole number: 26

So,

26 people would prefer vanilla out of 86 people

The number of chips of different colors in Gail's bag is shown below:3 blue chips
4 pink chips
8 white chips
Gail takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Gail takes out a white chip in both draws?
A. $(8)/(15)$ + $(7)/(14)$ = $(217)/(210)$
B. $(8)/(15)$ × $(7)/(14)$ = $(56)/(210)$
C. $(8)/(15)$ + $(8)/(15)$ = $(16)/(15)$
D. $(8)/(15)$ × $(8)/(15)$ = $(64)/(225)$

Answers

Answer:

$(8)/(15) * (8)/(15)=(64)/(225)$

Step-by-step explanation:

Given : 3 blue chips

4 pink chips

8 white chips

To Find: What is the probability that Gail takes out a white chip in both draws with replacement?

Solution:

Blue chips =3

Pink chips =4

White chips =8

Total chips = 3+4+8 =15

Now Probability of getting white chip on first draw = $\frac{\text{Number of white chips }}{\text{Total no. of chips}}$

= $(8)/(15)$

Now ,She replaces the chip and then takes out another chip from the bag.

So, Probability of getting white chip on second draw = $(8)/(15)$

Probability of getting white chip in both draws = $(8)/(15) * (8)/(15)=(64)/(225)$

Hence the probability that Gail takes out a white chip in both draws is $(8)/(15) * (8)/(15)=(64)/(225)$

Thus Option D is correct.

most likely the probability is D because my mom said it is d i dont know how she got it
