If A = 50 degrees, B = 62 degrees, and a = 4, find b.

Round to the nearest tenth.​

If A = 50 Degrees, B = 62 Degrees, And A = 4, Find B. Round To The Nearest Tenth.

Answers

Answer 1
Answer:  4.6

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

Work Shown:

Use the law of sines

b/sin(B) = a/sin(A)

b/sin(62) = 4/sin(50)

b = sin(62)*4/sin(50)

b = 4.61042489526572

b = 4.6

Make sure your calculator is in degree mode.

If you need only 1 c of milk, what is your best choice at the grocery store---- a quart container, a pint container, or a 1/2 gal container?

Answers

Step-by-step explanation:

Since 1 gallon = 4 quarts ⇒ (1/2) gallons = 2 quarts

1 gallon = 8 pints ⇒ (1/2) gallons = 4 pints

1 gallon = 16 cups ⇒ (1/2) gallons = 8 cups

Therefore from the given relation with gallons we can describe the relation between the cups, quarts and pints.

(1/2) Gallon > quarts > pints > cups

If we need 1 cup of milk then a pint container will be the best choice at a grocery store.

The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 1/5 ampere when the resistance is 8750 ohms. What is the current when the resistance is 17150 ​ohms?

Answers

Answer:

0.102048 ampere

Step-by-step explanation:

I α k / R

Current = 1/5 ; R = 8750

What is the current when the resistance is 17150 ​ohms

First obtain the value of k :

I = k/R

I = 1/5 ampere = 0.2 A

0.2 = k / 8750

k = 1750

What is the current when the resistance is 17150 ​ohms

I = 1750 / 17150

I = 0.1020408

I = 0.102048 ampere

6x - 7 = 11 show the step as well please

Answers

Answer:

x = 3

Step-by-step explanation:

6x - 7 = 11

First, add 7 to 11 which gets you 6x = 18

Then, divide 18 by 6 to solve for x which gets you 3

This means that x = 3

(hope this helps)

Answer:

Step-by-step explanation:

6x-7+11

(add 7 to both sides, canceling out the negative 7 on the left, and resulting in a sum of 18 on the right)

6x=18

(divide both sides by 6, which should isolate x because the sixes will cancel each other out, and give you a quotient of 3 on the right side)

the temperature t at which water boils is inversely proportional to the number of feet F the water is above sea level. write the related variation equation

gives us the temperature in degrees Fahrenheit at a depth in feet below Earth’s surface. Consider the Atlantic Ocean, which covers 22% of Earth’s surface. At a certain location, at the depth of 500 feet, the temperature may be 28°F.

The related variation equation where k is the constant of proportionality is [tex]t=\frac{k}{F}[/tex]

For inverse variation, if a is inversely proportional to b. This is expressed as:

[tex]a \alpha \frac{1}{b}[/tex]

Introducing the constant of variation will give;

[tex]a=\frac{k}{b}[/tex]

Applying the concept to the question:

If the temperature t at which water boils is inversely proportional to the number of feet F, this is expressed as:

[tex]t \alpha \frac{1}{F}[/tex]

[tex]t=\frac{k}{F}[/tex]

Hence the related variation equation where k is the constant of proportionality is [tex]t=\frac{k}{F}[/tex]

There are between 24 and 40 students in a class.
The ratio of boys to girls is 4:7
How many students are in the class?

Answers

Given:

There are between 24 and 40 students in a class.

The ratio of boys to girls is 4:7

To find:

The number of students in the class.

Solution:

Let the number of boys are girls are 4x and 7x respectively, where, x must be a positive integer because number of boys and girls is always a positive integer. Then, the total number of students is

[tex]\text{Total students}=4x+7x[/tex]

[tex]\text{Total students}=11x[/tex]

It means total number of students is multiply of 11.

Multiples of 11 are 11, 22, 33, 44, ... . So, multiples of 11 between 24 and 40 is 33.

Therefore, the total number of students in the class is 33.

​

Answers

L=W+7

W=1/3L

we can substitute the width in the first relation with 1/3L

L=1/3L+7

we move1/3L to the left

L-1/3L=7

we multiply by 3 to remove the denominator

3L-L-21

2L=21

L=21/2=10.5cm

Answer:

l = (21/2)m

Step-by-step explanation:

Let's call the length l and width as w.

l = w+7m

(1/3)l=w (Plug in the w value into the first equation)

l = (1/3)l+7m (Now, isolate the l)

(2/3)l = 7m (Multiply both sides by 3/2)

l = (21/2)m
