I’m like super confused can somebody help me please?

Answer:

[tex]B = 38[/tex]

Step-by-step explanation:

This question can be illustrated using the attachment and the required bearing will be calculated using cosine theorem;

[tex]b^2 = a^2 + c^2 - 2ac\ CosB[/tex]

In this case:

[tex]b = 5[/tex]

[tex]a = 7[/tex]

[tex]c = 8[/tex]

[tex]<B = ??[/tex]

Substitute these values in [tex]b^2 = a^2 + c^2 - 2ac\ CosB[/tex]

[tex]5^2 = 7^2 + 8^2 - 2 * 7 * 8\ CosB[/tex]

[tex]25 = 49 + 64 - 112\ CosB[/tex]

[tex]25 = 113- 112\ CosB[/tex]

Collect Like Terms

[tex]25 -113=- 112\ CosB[/tex]

[tex]-88=- 112\ CosB[/tex]

Divide through by -112

[tex]\frac{-88}{-112}= \frac{- 112\ CosB}{-112}[/tex]

[tex]\frac{-88}{-112}= CosB[/tex]

Reorder

[tex]Cos\ B = \frac{-88}{-112}[/tex]

[tex]Cos\ B = 0.7857[/tex]

Take arccos of both sides

[tex]B = cos^{-1}(0.7857)[/tex]

[tex]B = cos^{-1}(0.7857)[/tex]

[tex]B = 38[/tex] --- (approximated)

Hence, the bearing is approximately 38 degrees

Answer: 41%

Step-by-step explanation:

15 girls prefer biology.

Find the boys who prefer biology;

There are 36 girls in total so;

= 100 - 36

= 64 boys interviewed

14 boys prefer Physics

= 64 - 14

= 50 boys prefer Biology and Chemistry

7 out of the 31 who prefer chemistry are girls so the boys who prefer chemistry are;

= 31 - 7

= 24 boys

Boys who prefer Biology;

= 50 - 24

= 26 boys

Total who prefer biology;

= 15 girls + 26 boys

= 41 students

Percentage = 41/100 = 41%

The least number of cabins needed for campers is 8.

Given that, Shady Rivers summer camp has 188 campers this week.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

The least number of cabins needed = Total number of campers/Number of campers to each cabin

= 188/22

= 8.54

Therefore, the least number of cabins needed for campers is 8.

Answer: Point A

Step-by-step explanation:

The temperature at midnight is;

= 5 - 15

= -10°C

Looking at the number line, one can surmise that the scale is in multiples of 5. This means that C is 10, B is -5 and A is -10.

With point A being -10°C, it represents the colder midnight temperature.

Answer:

Point A

Step-by-step explanation:

We know that the temperature dropped 15 degrees, and that it was initially of 5°C. So, by midnight, the temperature will be of -10°C (5-15=-10).

We also know that the distance between points is of 5°C. So, the point that we have to mark is point A, which represents -10°C.

Answer: Rs 1469

Step-by-step explanation:

Coat of item = RS 1300

Value added tax = 13%

The price of the item will then be calculated as:

= 1300 + (1300 × 13%)

= 1300 + (1300 × 0.13)

= 1300 + 169

= Rs 1469

Answer:

Slope is rate of change, so define your values.

-$100 is the initial fee

-$70 is charged per month

per month is the constant rate of change

70 is the slope

The slope (rate of change) of the function is 70.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given:

Verizon charges a $100 initial contract fee,

then $70 a month for a basic cell phone plan.

Let the x be the number of months.

So, the equation,

y = 70x + 100

By comparing with the slope-intercept form,

y = mx + b, where m is the slope.

So, m = 70.

Therefore, 70 is the slope.

The numbers is 44/3 and 22/3 are that numbers.

Given that

The sum of two numbers is 22.

One of the numbers is two times the other.

To find

What are the numbers ?

So, according to the question

Let's assume that numbers are x and y, where x is greater then y.

So, we can say that

The sum of that numbers,

x+y = 22,  -------------(1)

And

One of the numbers is two times the other.

x = 2y ---------------(2)

Now, put the value of eq(1) in eq(2)

So, we will get

x+y = 22,  -------------(1)

2y+y = 22

3y = 22

y = 22/3

Now, put the value of y in eq(2)

So, we will get

 x = 2y ---------------(2)

x = 2 (22/3)

x = 2 ×[tex]\frac{22}{3}[/tex]

x = 44/3

That numbers are 44/3 and 22/3.

The radius of the circle is 4 units

The equation of the circle is given as:

(x + 5)^2 + (y - 3)^2 = 4^2

The general equation of a circle is given as:

(x - a)^2 + (y - b)^2 = r^2

Where r represents the radius

By comparing both equations, we have:

r^2 = 4^2

Take the square root of both sides

r = 4

Hence, the radius of the circle is 4 units
