Problem 1

Answer: x = 9

----------

Explanation:

For now focus on triangle DEF. We need to find the missing angle D.

D+E+F = 180

D+71+42 = 180

D+113 = 180

D = 180-113

D = 67

In order for DE to be parallel to GH, the alternate interior angles EDF and GHF must be congruent

Let's see what happens when we force them to be equal

angle EDF = angle GHF

67 = 5x+22

67-22 = 5x

45 = 5x

5x = 45

x = 45/5

x = 9

Problem 2

Answers:

Converse: "if it is winter, then it is snowing"

Inverse: "If it is not snowing, then it is not winter"

Contrapositive: "If it is not winter, then it is not snowing"

----------

Explanation:

The original conditional is in the form "If P, then Q". The P and Q are placeholders for logical statements.

We then have the following forms

converse = "if Q, then P" (swap P and Q)inverse = "If not P, then not Q" (negate each)contrapositive = "If not Q, then not P" (do both inverse and converse operations)

==========================================

Problem 3

Answer: choice B) "If the sum of two angles is not 180 degrees, then they aren't supplementary"

----------

Explanation:

Refer to problem 2 for the general form of the inverse. We negate each of the P and Q to get our final answer.

==========================================

Problem 4

Answer: Choice C) "If I do not need an umbrella, then it is not raining"

----------

Explanation:

Refer to problem 2 for the general form of the contrapositive. We swap P and Q, and negate each.

==========================================

Problem 5

Answer: Choice A) "If two lines have opposite slopes, then they are perpendicular"

----------

Explanation:

Refer to problem 2 for the general form of the converse. We swap the positions of P and Q.

Rena’s grandfather opened a savings account as a college fund for her. His initial deposit and the yearly simple interest rate are shown.

A college graduate is shown walking up stairs. The bottom step represents three thousand five hundred dollars. The value of the top step is unknown. The distance up the stairs is labeled four years. The simple interest rate is three point two five percent.

How much will Rena have in this account after 4 years?

Enter the correct answer in the box.

Answers

Answer:

Total amount (A) = $3,955

Step-by-step explanation:

Given:

Initial deposit (P) = $3,500

Rate of interest  (r) = 3.25%

Number of years (t) = 4

Find:

Total amount (A)

Computation:

Simple interest = (p)(r)(t)

Simple interest =  (3,500)(3.25)(4)

Simple Interest = $455

Total amount (A) = Initial deposit (P) + Simple Interest

Total amount (A) = 3,500 + 455

Total amount (A) = $3,955

At the amusement park, the Ferris wheel is located 95 feet east and 156 feet north of the entrance. The swings are located 23 feet west and 124 feet north of the entrance. If Jalen is standing exactly three-eights the distance from the Ferris wheel to the swings, to the nearest hundredth of a foot, find the direct distance between Jalen and the entrance.

Answers

Answer:

113.18

Step-by-step explanation:

[tex]\sqrt{113^{2}+32x^{2}[/tex]

SF=113.18

The direct distance between Jalen and the entrance is 144.6 feet.

What is distance?

The distance of an object can be defined as the complete path travelled by an object .Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.

Given:

Place everything on an xy grid with the Entrance at (0,0).

Then the Ferris Wheel is at (95,156) and the Swings are at (-23,124).

Cody is halfway between them,

so he is at

(95-((95-(-23)/2)),156-(156-124/2) or (36,140).

The distance from Cody to the entrance, using Pythagoras, is square root of

(362+1402)

=144.6 feet

Therefore , the direct distance between Jalen and the entrance is 144.6 feet.

Answers

Answer:

This equation has 4 solutions, its real solutions are x = -1 and 3

Step-by-step explanation:

Correct for Plato Users

The equation has 4 solutions and its real solutions are 3, -1.

The given polynomial equation is 6(x - 3)(x² + 4)(x + 1) = 0.

What does a real solution mean in math?

A real solution in algebra is simply a solution to an equation that is a real number.

Now, 6(x - 3)(x² + 4)(x + 1) = 0

⇒(x - 3)(x² + 4)(x + 1) = 0

⇒(x - 3)=0, (x² + 4)=0 and (x + 1) = 0

⇒x=3, -1 and ±√-4.

Therefore, the equation has 4 solutions and its real solutions are 3, -1.

It's x=y/12, I just need to know how to work it out.

Answers

Step-by-step explanation:

Answer:-

[tex]\tt{y = 4x+8x}[/tex]

First, we need to add up the x.

We know that 4+8 = 12, so

[tex]\tt{4x+8x=12x}[/tex]

Now, equating it to y,

[tex]\tt{y = 12x}[/tex]

Now, if I multiply [tex]\tt{\dfrac{1}{12}}[/tex] on both sides,

I get,

[tex]\tt{\dfrac{y}{12}= \dfrac{\cancel{12}x}{\cancel{12}}}[/tex]

Now, as 12 got cancelled , I got the final answer as
