Remark

You are given 2 items and ask for a third. That is a classic trig question.

Givens

angle = 27

opposite side = 18

hypotenuse = ?

Solution

Sin(27) = opposite side / hypotenuse

Sin(27) = 18 / hypotenuse                         Multiply by the hypotenuse

hypotenuse * sin(27) = 18                         Divide by sin(27)

hypotenuse = 18 / sin(27)

hypotenuse = 18 / 0.45699

hypotenuse = 39.6484

This is a very difficult question to pick an answer for. Everything depends on what you have been told about 5 when rounding. I always use a very simple method. It the rounded number is a 5 then you bounce the answer up. Otherwise leave it alone.

I think the correct answer (according to my rule) is that the answer is C, but your teacher could actually use a rule which would round it up to 39.7. I'm going to answer C but if you get it wrong, then D is the answer.

Answer:

slope - 1  y int - (0,0)

Step-by-step explanation:

to find the y intercept you go to where x equal 0 and when x equals 0 y also equals 0 so the y intercept is (0,0)

the slope is change in y over change in x and as y goes up 1 x goes up 1 1/1=1 so the slope is 1

Step-by-step explanation:

At the end of the 2 week, both Mary and Ardella has an equal amount of saving i.e. $140.

Mary and Ardella are saving money for a trip. Mary started her savings with $20 and is now saving $12 each week. Ardella started her savings with $40 and is now saving $10 each week. After how many weeks will Mary and Ardella have saved the same amount of money To determine,

In mathematics, it deals with numbers of operations according to the statements.

Let the number of weeks is x and total saving is y.
Now equation for Mary started her savings with $20 and is now saving $12 each week.
y = 12x +20 - - - (1)

The equation for Ardella, started her savings with $40 and is now saving $10 each week.
y = 10x + 40   - - - - (2)

Equating equation 1 and 2
12x +20 = 10x +40
12x -10x = 40 -20
2x = 20
x = 20/2
x = 10

Now put this x in equation 1
y = 12 * 10 + 20
y = 140

Thus, at the end of the 2 week both Mary and Ardella has an equal amount of saving i.e. $140.

Answer:

x = 89, y = 38

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the given angles and equate to 180

x + 53 + 38 = 180

x + 91 = 180 ( subtract 91 from both sides )

x = 89

y and 38 are alternate angles and are congruent, then

y = 38

Answer:

61.68 mg

Step-by-step explanation:

Given the table :

5:00pm - 400mg

6:00pm - 350mg

7:00pm - 306.25mg

First we obtain the percentage rate at which the drug leaves her system per hour :

Take between 5-6 pm

((400 - 350) / 400) * 100%

(50 / 400) * 100%

0.125 * 100%

= 12.5%

.we can use the exponential function :

A = P(1 - r)^t

r = rate, t = time (hours) ; P= initial amount ; A = final amount

Mg of medicine left when she wakes up at 7:00 am

t = 7:00am - 5:00 pm = 14 hours

P = 400 mg

r = 0.125

A = 400(1 - 0.125)^14

A = 400 * 0.1542100

A = 61.68402913

About 61.68 mg

Cris eats the least amount of cake.

A word problem is a few sentences describing a 'real - life' scenario where a problem needs to be solved by way of a mathematical calculation.

Given is that Luisa eats more cake than Cris. María eats more cake than Cris and less than Rosa, but she eats more than Luisa.

Let's assume that -

x > y                             ... (1)

w > z > y                         ... (2)

z > x                            ... (3)

We can write -

Maria > Luisa > Cris

Rosa > Cris

The inequality can be written as -

Maria > Luisa > Cris < Rosa

Therefore, Cris eats the least amount of cake.

Given:

Last year, Dr. Alvarado saw 540 patients.

This year, he saw 1053 patients.

To find:

The percent of increase in the number of patients seen each year.

Solution:

We know that,

[tex]\%\text{Increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]

On substituting the given values, we get

[tex]\%\text{Increase}=\dfrac{1053-540}{540}\times 100[/tex]    

[tex]\%\text{Increase}=\dfrac{513}{540}\times 100[/tex]

[tex]\%\text{Increase}=\dfrac{5130}{54}[/tex]

[tex]\%\text{Increase}=95\%[/tex]

Therefore, the number of patients increased by 95% each year.

Answer:

Step-by-step explanation:

Answer:

18 tablespoons of blue paint; 3 batches

Step-by-step explanation:

For 1 batch of paint, she uses 2 cups of white paint and 6 tablespoons of blue paint.

She needs to mix blue paint using 6 cups of white paint.

6 cups is 3 times 2 cups, so she will be making 3 batches.

She also needs to use 3 times the amount of blue paint that she would use for 1 batch.

Since she uses 6 tablespoons of blue paint in 1 batch, she needs to use 3 times as much blue paint.

3 * 6 tablespoons = 18 tablespoons.

Answer:

15/14

Step-by-step explanation:

I am assuming you meant. 3(x+1/2)

10x-6=3x+3/2

7x=3/2+12/2

7x=15/2

x=15/2*1/7

x=15/14

The value of x from the given equation is 15/14.

The given equation is 10x-6=3(x+1/2)

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved as follows

10x-6=3x+3/2

⇒ 10x-3x=3/2 +6

⇒ 7x = (3+12)/2

⇒ 7x = 15/2

⇒ x=15/14

Hence, the value of x from the given equation is 15/14.

Answer: y = 11.25

Step-by-step explanation:

Mi espanol es terrible :l

Todos los angulos terminaran acompletando 90° grados

Entonces hagamos una ecuacion

3y + 4y + y = 90

8y = 90

Divide por 8

y = 11.25

Esta parte no es necesaria

Para ver si es verdad hagamos el math

3(11.25) = 33.75

4(11.25) = 45

y = 11.25

33.75 + 45 + 11.25 = 90
