What is the value of X in degrees?
A.13.8
B.16
C.20
D.24

Answers

Answer:

B. 16 degrees

Step-by-step explanation:

Because all of the angles in a triangle add up to 180 degrees, you can set up an equation for this problem:

2x - 10 + 4x + 46 + 3x = 180

Start by consolidating everything by adding like terms.

9x + 36 = 180

Then subtract 36 from both sides.

9x = 144

Then divide both sides by 9 to get your x.

x = 16

0.1 (0.5 + 6) = 2
I thank you a million who ever helps me

Answers

Answer:

m = 28

Step-by-step explanation:

Simplifying

0.1(0.5m + 6) = 2

Reorder the terms:

0.1(6 + 0.5m) = 2

(6 * 0.1 + 0.5m * 0.1) = 2

(0.6 + 0.05m) = 2

Solving

0.6 + 0.05m = 2

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-0.6' to each side of the equation.

0.6 + -0.6 + 0.05m = 2 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0

0.0 + 0.05m = 2 + -0.6

0.05m = 2 + -0.6

Combine like terms: 2 + -0.6 = 1.4

0.05m = 1.4

Divide each side by '0.05'.

m = 28

Simplifying

m = 28

First multiply 3 and 4 to get 12. Now, we must get two numbers that multiply to 12, but also add to -8. The answer is -6 and 2.

Now rewrite this expression as “3x^2-6x+2x+4.

Now, group together each set of two terms and find the GCF of each. The GCF of 3x^2 and -6x is -3x. The GCF of 2x and 4 is 2.

Now, divide each group by the GCFs and place them next to each other. You should get -3x(x+2)+2(x+2). We know this is correct because the parentheses match.

Now, rewrite the duplicate factors as one, and group together what is outside the parentheses. The final answer is...

(-3x+2)(x+2).

To check, you can double distribute (FOIL) to see if it matches the original expression.

Step-by-step explanation:

The sum of a geometric series with first term a1 is ...

  S = a1/(1 -r)

Then the common ratio (r) is ...

  r = 1 -a1/S

For the given values, the ratio is ...

  r = 1 - 124/64 = -15/16

The common ratio is -15/16.

the wheel?

49.7 cm?
198.9 cm?
99.5 cm
19.6 cm?

Answers

Answer:

49.7 [tex]cm^{2}[/tex]

Step-by-step explanation:

Although it is hidden a bit, we are actually given the circumference of the circle, which is 25 cm.

We know that C = 2πr, so we can substitute variables to find the radius (r).

25 = 2πr

r = 25/(2π)

r = 3.9788... cm

The area of a circle is A = π[tex]r^{2}[/tex], so:

A = π [tex]3.9788^{2}[/tex]

A = 49.7359... [tex]cm^{2}[/tex]

A ≈ 49.7 [tex]cm^{2}[/tex]

Jacob went on a fishing trip. This year he caught 30 fish, which is six more than twice the number he caught last year. How many fish did Jacob catch last year?

Answers

Answer:

12 fish

Step-by-step explanation:

You need to work this problem backwards. If he caught 30 fish, which was six more than twice the number he caught last year, you would start by subtracting six, leaving you with 24. Then you'd have to divide by 2, because it was twice plus six as many fish, which would give you 12 fish.

[tex]\frac{30-6}{2}[/tex] = x

[tex]\frac{24}{2}[/tex] = x

Zx and Zy are supplementary angles. Zy measures 142º.
What is the measure of Zx?

Answers

Supplementary angles means the sum will be 180 degrees. So since Zx = 142 degrees, allow: 180 = 142 + Zy. So, 180 - 142 = 38 degrees = Zy.
