Find the value of x and classify the triangle plzzz

Answers

Answer:

x=24°

The triangle is an obtuse isosceles triangle

Step-by-step explanation:

This is an obtuse isosceles triangle because it has two congruent sides, making it an isosceles triangle, and there is an obtuse angle, which is any angle greater than 90°.

The interior angles of a triangle add up to 180, so let's make an equation.

132+2x=180

Then solve for x

subtract 132 from both sides

2x=48

Divide by 2 on both sides

x=24

The answer would be X=24 obtuse isosceles triangle

Janice bought an antique clock originally priced at $967 but on sale for 5% off. After 1% sales tax, what was the total cost?

Answers

Answer:

927.84

Step-by-step explanation:

The total cost of the antique clock that Janice bought is $927.82 approximately.

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we have:

Original price of clock = $967Sale discount  = 5% on original price1% sales tax on the discounted price

Total cost = (discounted price of clock)'s price + sales tax of discounted price.

Let d = discounted price of the clock

Then, we have:

[tex]d = $967 - \text{5\% discount on 967} \\\\d = 967 - \dfrac{967}{100} \times 5 = \$918.65[/tex]

1% sales tax on 'd' will be: [tex]\dfrac{d}{100} \times 1 = \$9.1865 \approx \$9.19[/tex]

Thus, we get:

Total cost of the clock ≈ 918.65 + 9.19 = 927.82 (in dollars)

Thus, the total cost of the antique clock that Janice bought is $927.82 approximately.

The answer is D. Here’s the explanation:
Take out the constants: 20/4 x a^(-4)b(-3)c^(2) / a^(2)b^(-6)c^(5)
Simplify the 20/4 to 5.
Use the Quotient Rule which is x^a / x^b = x^(a-b)
5a^(-4-2)b(-3+6)c(2-5)
Simplify (-4-2) to -6.
Simplify (-3+6) to 3.
Simplify (2-5) to -3.
You’re left with 5a^(-6)b^(3)c^(-3)
Use negative power rule which is x^(-a) = 1/x^(a)

Is 14 a solution for the equation -5 + 2x = 23? Explain.

Answers

Answer:

Yes because after solving the equation, x does indeed equal 14.

Step-by-step explanation:

-5 + 2x = 23

2x = 23 + 5

2x = 28

x = 14

Answer:

-5 + 2x= 23 x= 14 (Correct)

Step-by-step explanation:

This is true because the first step you take to sloving this equation is to move the constant to the right. Then calculate. Divide both sides and your answer should equal x=14!

Someone help me out. So the question is Distance = Rate x Time What is the distance traveled if it took me 3 hours to travel at a rate of 60 miles per hour?

Answers

Answer: 180 miles

Step-by-step explanation:

From the question, we should note that the distance taken will be calculated by using the formula which will be:

Distance = Rate × Time

where,

Rate = 60 miles per hour

Time = 3 hours

Distance = 60 × 3

Distance = 180 miles

Therefore, the distance travelled is 180 miles.

Consider the system of equations.


3x − y = 5,

2x + 3y = −15


Which value can the first equation be multiplied by to form opposite values on the y-term? A=-3 B= -2 C=2 D=3

The solution to the system of equations is .A= (-5,0) B= (5,0) C= (0,-5) D=(0,5)

Answers

Answer:

D and C

Step-by-step explanation:

Given the 2 equations

3x - y = 5 → (1)

2x + 3y = - 15 → (2)

Multiplying (1) by 3 and adding to (2) will eliminate the y- term

9x - 3y = 15 → (3)

Add (2) and (3) term by term to eliminate y

11x + 0 = 0

11x = 0 ⇒ x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (2)

2(0) + 3y = - 15

0 + 3y = - 15

3y = - 15 ( divide both sides by 3 )

y = - 5

solution is (0, - 5 )

Answer:

  c.  x = 7-t; y = -1/(t -7)

Step-by-step explanation:

To find the parametric equation for x, use the equation for t and solve for x.

  t = 7-x

  x = 7 -t . . . . . . add x-t to both sides

__

To find the parametric equation for y, substitute the equation for x.

  y = 1/x

  y = 1/(7-t)

To make this match the available choices, we need to multiply numerator and denominator by -1.

  y = -1/(t -7)

The parametric equations are ...

  x = 7 -t; y = -1/(t -7) . . . . . . matches choice C
