80 dollars and 50 cents.

Step-by-step explanation:

youd first multiply 70 by .15 which would equal 10.5. then add the 70 and 10.5 together. then you get your answer. so the expression youd want to use would be "x=70×.15"

Answer:

x-intercept: (3,0)

y-intercept: (0,9)

Answer:

(3,0) (0,9)

Step-by-step explanation:

To find the x-intercept, y must equal 0

9x+3(0)=27 substitute

9x=27 divide

x=3 (3,0)

To find the y-intercept, x must equal 0

9(0)+3y=27 substitute

3y=27 divide

y=9 (0,9)

Answer: either I don't understand the question or its 72% and I'm fairly certain its 72%

Answer:

$6.20

Step-by-step explanation:

We can covert 15% to a decimal by moving the decimal point two places over.

15% = 0.15

41.32 X 0.15 = 6.198

6.198 ≈ $6.20

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Original price: $41.32

Tip: 15% = %6.189

Total amount = = Original price + Tip amount

The total amount is $47.509

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Original price: $41.32

Tip: 15%

Now,

The amount of the tip.

= 15% of 41.32

= 15/100 x 41.32

= $6.189

The total amount.

= Original price + Tip amount

= 41.32 + 6.189

= $47.509

Thus,

Original price: $41.32

Tip: 15% = %6.189

Total amount = = Original price + Tip amount

The total amount is $47.509

Answer:

[tex] \theta) = 21.3 degrees [/tex] (nearest tenth)

Step-by-step explanation:

Reference angle = θ

Opposite side = 16 (length of the side opposite the reference angle)

Hypotenuse = 44

Apply trigonometric function SOH:

[tex] sin(\theta) = \frac{Opp}{Hyp} [/tex]

Substitute

[tex] sin(\theta) = \frac{16}{44} [/tex]

[tex] \theta) = sin^{-1}(\frac{16}{44}) [/tex]

Answer:

a = -4

Step-by-step explanation:

a + c = 6

substitute 10 for 'c'

a = -4

Answer:

a has to be a negative since c is equal to 10 so a is -4 because -4 + 10= 6

Answer: 11

Students have both a brother and a sister

Step-by-step explanation:

I don't think probability should be used for this question because the answer is quite clear

So in a class of 25 students

5 students don't have a sibling

So 25-5=20

Total number of siblings=14+17=31 siblings in total

So 20 people have 31 siblings

31-20=11

So the answer should be 11

In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings. The probability that a student who has a brother also has a sister is 11/25.

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events that belong to E, and total cases are the size of the sample space.

In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings.

So in a class of 25 students

5 students don't have a sibling

then, 25-5=20

Total number of siblings = 14+17

= 31 siblings in total

So, 20 people have 31 siblings

= 31 - 20

= 11

So, the probability that a student who has a brother also has a sister

= 11/ 25.
