Answer:

To find slope intercept, you must use the substitute term for slope, m, and then use the following equation. ↓

[tex](y = mx+b)[/tex]

Next, you want to use these terms to help you solve for b. ↓

[tex]Slope = m\\Points = x, y\\y-intercept = b[/tex]

Answer:

y=mx+b

Step-by-step explanation:

The slope intercept form is y=mx+b

M = slope

B = y-intecept

and when you substitue the numbers for the variables then you have it in slope-intercept formula

Answer:

109

Step-by-step explanation:

the sum of 37 and 72 is equal to x

proof:  

37+72 = 109

three angles of a triangle form 180 degree

to find the angle which is not given,

180 - 109  = 71

as you can see, angle with the measure 71 degree and angle x form a straight line, which means their sum is 180

so,

x = 180 - 71

x = 109

that means ,

=>    37+72 = x

=>    109 = 109            [ 37+72 = 109, x = 109]

hope this helps :)

Answer:

Step-by-step explanation:

Find the value of x in this triangle .

We know that sum of all the interior angles of triangle is equal to 180° . Then ,

Therefore , Angle y = 71° .

Now , We know that Angle 3 and Angle 4 is equal to 180° because they are Linear pair . So ,

Therefore , value of Angle x is 109° .

Answer:

48.81

Step-by-step explanation:

Since we are given a right triangle, and we are trying to find a angle, we use the

SOH-CAH- TOA.

In relation to the angle, we know a side opposite of the angle and the side adjacent to the angle.

We use Tangent, which states that

[tex] \tan(x) = \frac{o}{a} [/tex]

Here the opposite side is 8

The adjacent side is 7.

[tex] \tan(x) = \frac{8}{7} [/tex]

Take the Inverse Tangent,

[tex] \tan {}^{ - 1} (( \tan(x) ) = \tan {}^{ - 1} ( \frac{8}{7} ) [/tex]

[tex]x = \tan {}^{ - 1} ( \frac{8}{7} ) [/tex]

Which gives us 48.81

Answer:

∠ A ≈ 48.81°

Step-by-step explanation:

using the tangent ratio in the right triangle

tan A = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{8}{7}[/tex] , then

∠ A = [tex]tan^{-1}[/tex] ( [tex]\frac{8}{7}[/tex] )  ≈ 48.81° ( to the nearest hundredth )

The circle illustrates the theorems of angles in the same segment

Given that:

∠SKA = 74°

The angle SKA is at the center of the circle.

This means that:

Arc AS = 74°

Calculate Arc SN using:

SN + AS = 180°

Substitute 74 for AS

SN + 74° = 180°

Subtract 74 from both sides

SN = 106°

The arc SN is subtended by the angle NTS.

This means that:

∠NTS = 0.5 * SN

So, we have:

∠NTS = 0.5 * 106°

Evaluate

∠NTS = 53°

Hence, the measure of angle NTS is 53°

Given that:

∠BCA = (7w - 4)°

∠ADB = (5w + 20)°

Angles subtended by the same arc at the circumference are congruent.

So, we have:

7w - 4 = 5w + 20

Collect like terms

7w - 5w = 20 + 4

Evaluate

2w = 24

Divide by 2

w = 12

This implies that:

∠BCA = (7 * 12 - 4)°

Evaluate

∠BCA = 80°

The measure of arc AB is then calculated using:

AB = 360 - 2 * ∠BCA

This gives

AB = 360 - 2 * 80°

Evaluate

AB = 200°

Hence, the measure of arc AB is 200°

Answer:

Step 2-3

Step-by-step explanation:

I don't know what's wrong with step 2 but in step 3 the student added the exponent instead of multiplying.

That automatically makes every other step done afterwards wrong but it's not 3-4 because the math is right it's just that step 3 messed up step 4 laws of exponent wise.

The distance between Vega 3 and the Mars (MV) illustrates cosine function, and the distance is 29.1 million light years or 142.8 million light years

From the question, we have the following parameters

See attachment for the illustration of the given parameters.

The distance between Vega 3 and the Mars (MV) is then calculated using the following cosine function

VS² = MS²+ MV² - 2 * MS * MV * cos(Ф)

This gives

4489 = 8649+ MV² -  171.96MV

Subtract 8649 from both sides

MV² -  171.96MV = -4160

Rewrite as:

MV² -  171.96MV + 4160 = 0

Using a graphing tool, we have:

MV = 29.1 and MV = 142.8

Hence, the distance between Vega 3 and the Mars is 29.1 million light years or 142.8 million light years

Answer:

128

Step-by-step explanation:

32 × 4 = 128

Each tank has 32, and there are four, so 32 times 4.

The store has 128 fish in the tank.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that pet store has 4 tanks of fish. Each tank has 32 fish.

Therefore,

Total fish =  Number of fish that a tank can hold x Number of tanks

32 × 4 = 128

Hence, we get 32 for each tank, and there are four,

Thus, 32 times 4.
