Can someone please help me with this algebra

Answer:

Explanation:

mGB = 90°

mGB = mBD

∴ mGD = 180°

⇒ mFE = 180 - (mDE + mFG)

mFE = 180 - (49 + 12)

mFE = 180 - 61

mFE = 119°

Answer:

119°

Step-by-step explanation:

[tex] In\: \odot A, [/tex] GD is diameter.

[tex] \therefore m\widehat{GFD} = 180\degree [/tex]

[tex] \because m\widehat {FG} +m\widehat {DE} = m\widehat {FE} \widehat{GFD} [/tex]

[tex] \therefore m\widehat {FG} +m\widehat {DE} + m\widehat {FE} = 180\degree [/tex]

[tex] \therefore 49\degree +12\degree + m\widehat {FE} = 180\degree [/tex]

[tex] \therefore 61\degree + m\widehat {FE} = 180\degree [/tex]

[tex] \therefore m\widehat {FE} = 180\degree - 61\degree [/tex]

[tex] \therefore m\widehat {FE} = 119\degree [/tex]

Answer:

163/500

Step-by-step explanation:

we will not only clearly explain how to get the answer to 0.326 as a fraction, but also prove to you that our answer is correct.

First, note that 1000 multiplied by .326 will get rid of the decimal point. Therefore, make a fraction where the numerator is .326 times 1000 and denominator is 1000 like this:

.326 x 1000

1000

Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:

326

1000

The greatest common factor of 326 and 1000 is 2, which means you can divide the numerator and denominator by 2 and keep the same value:

326 ÷ 2

1000 ÷ 2

And when calculating the numerator and denominator in our fraction above, we get .326 as a fraction in the simplest form possible:

.326 =

Answer:

The expression is [tex]T(n) = 2*(3)^n[/tex]

Step-by-step explanation:

Geometric sequence:

In a geometric sequence, the quotient between consecutive terms is always the same.

The general rule of an geometric sequence is given by:

[tex]T(n) = T(0)(q)^n[/tex]

In which T(0) is the initial amount and q is the quotient.

During the first 4 years after the fire, she records 2, 6, 18, and 54 trees.

First term is 2, so [tex]T(0) = 2[/tex].

Quotient is [tex]q = \frac{54}{18} = \frac{18}{6} = \frac{6}{2} = 3[/tex]

So

[tex]T(n) = T(0)(q)^n[/tex]

[tex]T(n) = 2*(3)^n[/tex]

The expression is [tex]T(n) = 2*(3)^n[/tex]

Answer:  ($3.50- 10% = 3.4)

Step-by-step explanation:

The final cost of milk is $ 3.36875

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.

Given:

price of galloon of milk = $3.50

Discount  = 10%

tax = 6.25%

Now, price after discount

=3.5 x 0.10

= 0.35

and, after tax

=3.5 x 0. 0625

= 0.21875

Hence, final cost of milk = 3.5 -0.35  + 0.21875= $ 3.36875

Answer:

y = 5/3x + 4

Step-by-step explanation:

First, you need to find the slope. Use the slope formula of (y^2-y^1) / (x^2 - x^1).

Plug the numbers in.

(4 - (-1)) / (0 - (-3))

5 / 3

Slope is 5/3

Now, you have an equation of y = 5/3x + b.

Since one of the points shows you what y equals when x=0, that is your y intercept.

Answer: Universal set

Step-by-step explanation:

A universal set is usually represented by U and it is set that has all the elements of a related sets.

For example, if there are two sets which are X and Y. Let's say X = {1,2,3} and Y = {1,a,b,c}, therefore, the universal set will be U = {1,2,3,a,b,c}.

In the above scenario, H(...-2,-10,1,2,...3) is a Universal set.

The scale on the map is 1 cm for 500 m.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

Given that, A man walks 1500 metres. on a map, this is shown as 3 cm.

3 cm = 1500 m

1 cm = 500 m

Hence, The scale on the map is 1 cm for 500 m.

The distance between the two points will be 10 units.

A coordinate plane is a 2D plane created by the junction of the x-axis and y-axis, two perpendicular lines. A coordinate system in geometry is a way to use one or more integers or coordinates to determine the positions of the points.

Given points are (1,3) and (5,6). The distance between the points will be calculated as below:-

D = √ [ ( y₂ - y₁ )² + ( x₂ - x₁ )² ]

Substituting the given values, we get:

D = √((3 - (-3))² + (-4 - 4)²)

D = √(6² + (-8)²)

D = √(36 + 64)

D = √(100)

D = 10

Therefore, the distance between the two points (-3, 4) and (3, -4) is 10 units.

Answer:

5.88 x 1012

Step-by-step explanation:

To write each of these numbers in decimal notation, you move the decimal point the same number of places as the exponent. If the exponent is positive, move the decimal point to the right. If the exponent is negative, move the decimal point to the left. If you start at the decimal of 5.88 and move it 12 spaces to the right, then you get 5,880,000,000,000 miles.

The number represented in scientific notation is 5.88×1013.

It is the way of writing a large number between 1 to 10 with a power of 10.

We have,

5,880,000,000,000 miles is equivalent to 1 light year.

We can convert this number to scientific notation by moving the decimal point 13 places to the left

(because there are 13 zeros in 5,880,000,000,000) and multiplying by 10 raised to the 13th power:

So,

= 5,880,000,000,000

= 5.88 × 10¹³

Therefore,

The number represented in scientific notation is 5.88×1013.

Step-by-step explanation:

Given:

Population of fish in 2002 = 2100 fish

Decrease rate = 3% per year

Find:

Population of fish in 2010

Computation:

Number of year = 2010 - 2002

Number of year = 8 year

A = P[1+r]ⁿ

Population of fish in 2010 = Population of fish in 2002[1+(-3%)]ⁿ

Population of fish in 2010 = 2100[1-0.03]⁸

Population of fish in 2010 = 2100[0.97]⁸

Population of fish in 2010 = 2100[0.7837]

Population of fish in 2010 = 1645.77

Population of fish in 2010 = 1,646 fish (Approx.)
