two angles in a triangle measure (2.3x+25)° and (5.8x+11)°. what is the value of x if the two angles are congruent to one another?

A. x= 34.2
B. x= 10.3
C. x= 6.6
D. x= 4

Answer:

C: Linear model

Step-by-step explanation:

Given:

∠1 = 2x+6 ans ∠2= -x+24

To find the values of ∠1 and ∠2.

Formula:

The values of the vertical angles are always equal.

Here,

∠1 and ∠2 are vertical angles.

So, by this condition,

∠1=∠2

or,[tex]2x+6 = -x+24[/tex]

or, [tex]2x+x = 24-6[/tex] [ Taking all the variables in one side and all the constant in other side]

or, [tex]3x = 18\\[/tex]

or, [tex]x = \frac{18}{3}[/tex]

or, [tex]x = 6[/tex]

So,

∠1 = [tex]2(6)+6 = 18^\circ[/tex]

∠2 =[tex]-6+24 = 18^\circ[/tex]

Hence,

The values of ∠1 and ∠2 are 18°.

Answer:

The ratio is 3:1

Step-by-step explanation:

Let

x --->number of neck less sold via the shop website

y --->number of neck less sold in a high street shop

we know that

To find out the ratio of online sales to shop sales, simply divided the number of neck less sold via the shop website by the number of neck less sold in a high street shop

so

[tex]ratio=\frac{x}{y}[/tex]

we have

[tex]x+y=240[/tex] ----> equation A

[tex]x=180[/tex] ---> given value

substitute the value of x in the equation A

[tex]180+y=240[/tex]

solve for y

[tex]y=240-180=60[/tex]

Find the ratio

Answer:

55, 125 and 125

Step-by-step explanation:

In this question, we are asked to find the other 3 angles in an intersection.

Please check attachment for what the diagram of the intersection might look like.

The intersection consists simply of 4 angles meeting at a point with the 2 angles on each side vertically opposite to the angles on the other side.

since one of the angles is 55, and we are having a straight line, the other angle would be 180-55 = 125.[ sum of angles on a straight line is 180]

These two angles are vertically opposite, this means that the other three angles are 55,125 and 125.

The applicable rules of logarithms are ...

  log(ab) = log(a)+log(b)

  log(a^b) = b·log(a)

Final answer:

To expand the expression In 2a³/b⁴, you apply logarithm properties to obtain In 2 + 3 In a - 4 In b, which separates the factors into individual log terms.

Explanation:

The question asks us to expand the logarithmic expression In 2a³/b⁴ using logarithm properties. The correct expansion of this expression is given by the sum of the logarithms of the numerator's factors minus the sum of the logarithms of the denominator's factors. Applying the properties of logarithms (product to sum and quotient to difference), we obtain the expansion as follows:

In 2a³/b⁴ = In 2 + In a³ - In b⁴

The logarithm of a power (such as In a³ and In b⁴) can be brought down as a coefficient:

In 2 + 3 In a - 4 In b

Thus, the correct expansion is In 2 + 3 In a - 4 In b.

Answer:

(a) 45 miles

(b) 38 miles

(c) Jada travels faster than Andre.

Step-by-step explanation:

(a) First we calculate the speed at which Jada travelled:

[tex]Speed = \frac{distance}{time} \\\\\\s = \frac{d}{t}[/tex]

[tex]s = \frac{135}{3} \\\\\\s = 45 miles/hour[/tex]

Since Jada travels at constant speed throughout the journey, we can calculate the distance traveled in 1 hour:

[tex]distance = speed * time\\\\\\distance = 45 * 1[/tex]

distance = 45 miles

Jada travels 45 miles in 1 hour.

(b) We calculate the speed at which Andre travelled:

[tex]Speed = \frac{distance}{time} \\\\\\s = \frac{d}{t}[/tex]

[tex]s = \frac{228}{6} \\\\\\s = 38 miles/hour[/tex]

Since Andre travels at constant speed throughout the journey, we can calculate the distance traveled in 1 hour:

[tex]distance = speed * time\\\\\\distance = 38 * 1[/tex]

distance = 38 miles

Andre travels 38 miles in 1 hour.

(c) Jada travels faster than Andre because he has a higher speed (45 miles/hour) than Andre ( 38 miles/hour).

Answer:

20, 40, and 120

Step-by-step explanation:

x, 2x, and 6x have one thing in common: X. X is the same number throughout so if we find x we can just finish the equation by multiplying x by its coefficient.

x+2x+6x = 180. (Sum of angle measures)

9x           = 180 (Add up the left side)

9x/9        = 180/9 (Divide both sides by 9 to cancel out the 9 and leave the x)

x              = 20

Now we know what x is so:

Angle 1 = 20. (We know x is 20, so that one is easy.)

Angle 2 = 40 (Simply 2*x or 2*20)

Angle 3 = 120 (Simply 6*x or 6*20)

Answer:

The degree of freedom for the test is 27.

Step-by-step explanation:

The experiment performed by the researcher is to determine the number of time the rat touches the specific object compared to a different object.

The parameter under study is the mean number of times the rat touches the specific object.

The hypothesis for the test is defined as:

H₀: The mean number of times the rat touches the specific object is not more than that for a different object, i.e. μ ≤ μ₀.

Hₐ: The mean number of times the rat touches the specific object is more than that for a different object, i.e. μ > μ₀.

A t-test for single mean is performed.

The information provided is:

α = 0.05

t = 2.842

n = 28

The degrees of freedom for a single mean t-test is:

df = (n - 1)

   = 28 - 1

   = 27

Thus, the degree of freedom for the test is 27.

Final answer:

To find out how many pizzas Charlie can make in one hour, divide the total number of pizzas he can make by the total number of hours he spends making them. Charlie can make 25 pizzas in one hour.

Explanation:

To find out how many pizzas Charlie can make in one hour, we need to divide the total number of pizzas he can make (125) by the total number of hours he spends making them (5).

So, the calculation would be: 125 pizzas / 5 hours = 25 pizzas per hour

Therefore, Charlie can make 25 pizzas in one hour.

Answer: $9

Step-by-step explanation: If Wendy wants to own a total of 12 necklaces, that means Wendy wants to buy 9 more necklaces, since she already owns 3. We know that each necklace is a dollar.

So if Wendy buys 9 necklaces for a dollar each, then the total price will be $9 for Wendy to own a total of 12 necklaces.

( 9 x 1 = 9)

Wendy has 3 necklaces, and she needs a total of 12. So 12 - 3 is 9. She'll need to buy 9 more necklaces.

If each necklace cost $1, that means for 9 necklaces she will spend $9.

1 × 9 = 9

That means $9 has to be spent, in order to own 12 necklaces.

Therefore, side opposite to angle HAM > side opposite to angle HKC

To multiply monomials, you multiply the coefficients and add the exponents of like variables. The product of -9n^3 and n^3 is -9n^6.

The question is about multiplying two monomials in mathematics. In this case, the two monomials are -9n^3 and n^3. To multiply monomials, you multiply the numerical coefficients and add the exponents of like variables. Here, the coefficient is -9 and the exponent 3 for the first monomial and 1 and 3 for the second monomial. When you multiply -9 by 1, you get -9. When you add the exponents 3 and 3, you get 6. So, the product of those two monomials in standard form is -9n^6.
