Answer:

∠A = 94°

Step-by-step explanation:

Two angles are called supplementary when their measures add up to 180°.

Therefore, if ∠A and ∠B are supplementary:

⇒ ∠A + ∠B = 180

⇒ (2x + 10) + (2x + 2) = 180

⇒ 4x + 12 = 180

⇒ 4x = 168

⇒ x = 42

To find ∠A, substitute found value of x into the expression for ∠A:

⇒ ∠A = 2(42) + 10 = 94°

According to projections through the year 2030, the population y of the given state in year x is approximated by
State A: - 5x+y=11,400
State B: -143x +y = 9,000
where x = 0 corresponds to the year 2000 and y is in thousands. In what year do the two states have the same population?

Answers

Answer:

In the year 2026 population of both the states will be the same.

Step-by-step explanation:

It has been given in the question that the population y of State A in year x will be represented by the equation

-3x + y = 11,400

⇒ y = 11,400 + 3x --------(1)

Similarly, an equation that represents the population for State B is

-138x + y = 8,000

⇒ y = 138x + 8,000 -------(2)

If population y for both the states are equal then

3x + 11,400 = 138x + 8,000

11400 - 8000 = 138x - 3x

135x = 3400

x = 25.19 [After 25 years ]

Since  x = 0 represents the population of the states in the year 2000

therefore, population y will be the same in both the states in the year (2000 + 26)

= 2026

Answer: B. The ball is less likely to be a racquetball than a golf ball.

Step-by-step explanation:

Imagine a bin. You are storing different sports balls in the bin. You put 20 baseballs, 24 golf balls, 9 tennis balls, and 6 racquetballs in the bin. Can you name which ball is most likely to be chosen if you grabbed one out at random? The answer is the golf ball.

This is because there are more golf balls than any other type of ball. For example, there are 24 golf balls, yet there are only 20 baseballs. This means that you are more likely to pick a golf ball.

Remember that there are 6 racquetballs while there are 24 golf balls. There are 4 times more golf balls than racquetballs in the bin. This means that you are 4 times more likely to pick a golf ball than a racquetball when you take a ball out of the bin at random.

Since there are many more golf balls than racquetballs, you are more likely to grab a golf ball than a racquetball. This means that the ball is less likely to be a racquetball than a golf ball.

(If you are confused, imagine freshly baked cookies. You cooked 12 cookies.

8 cookies are chocolate chip

3 cookies are oatmeal raisin

1 cookie is peanut butter.

If you grab a cookie at random, with your eyes closed, you are most likely to pick the chocolate chip cookies. This is because there are more chocolate chip cookies than oatmeal raisin cookies or peanut butter cookies)

Consider the following system of equations:
y = -x + 2
y = 3x + 1
Which description best describes the solution to the system of equations?
Line y = -x + 2 intersects line y = 3x + 1
Lines y = -x + 2 and y = 3x + 1 intersect the x-axis.
Lines y = -x + 2 and y = 3x + 1 intersect the Y-axis
Line y = -x + 2 intersects the origin

Answers

Answer:

Line y = -x + 2 intersects line y = 3x + 1

Step-by-step explanation:

The solution to a system of equations is the point at which the two lines intersect.  To find this point, first equate the equations and solve for x:

[tex]\begin{aligned}y & = y\\-x + 2 & = 3x + 1\\-x+2+x & = 3x+1+x\\2 & = 4x + 1\\2-1 & =4x+1-1\\1 &=4x\\x & =\dfrac14\end{aligned}[/tex]

Substitute the found value of x into one of the equations, and solve for y:

[tex]y=3\left(\dfrac14\right)+1=\dfrac74[/tex]

Therefore, the solution to the system of equations (the point at which the two lines intersect) is:

[tex]\left(\dfrac14,\dfrac74\right)[/tex]

So the description that best describes the solution to the system of equations is:

Line y = -x + 2 intersects line y = 3x + 1

Answer:

The son is 13 and the father is 39,

x= dad's age

y= 1/3x= boy's age

x+y=52

Substitute y=1/3x

x+1/3x=52

1 1/3x= 52

4/3x= 52

Multiply by reciprocal on both sides

(3/4)(4/3x)= (52)3/4)

x= (52*3)/4

x= 156/4

x=39 dad's age

Substitute x answer in to find boy's

y= 1/3x= 1/3(39)= (1*39)/3= 39/3= 13 boy's age

Step-by-step explanation:

Ratio of side of the 30-60-90 triangle is x : x√3 : 2x

Side opposite to 30° is the shortest leg and it is a

Side opposite to 60° is the longest leg and it is a√3

side opposite to 90° is hypotenuse and it is 2a and it the longest side.

7) a = 8 (Which is opposite to 30°)

 w = 2a = 2*8

w = 16

v = √3a = √3 *8

v = 8√3

8) a√3 = 5√3   (Which opposite to 60°)

   a = 5√3 ÷√3

y = a ⇒y= 5

x = 2a

  = 2*5

x = 10

9) hypotenuse = 10

2a = 10

a = 10 ÷ 2

a = 5

x = a√3

x = 5√3

y = a

y = 5

Six increased by product of x and four is 22. What is x?

Answers

Answer: 4

Step-by-step explanation:

Terms: Increased means adding, a product means multiplication.

1. Convert it into an equation: 6+4x=22

2. Then subtract 6 from the left side and pass it to the right to get 22-6= 16. Now, you have 4x=16.

3. Then you want to leave the x alone, so you divide both sides of the equation by 4.

4. Therefore, your answer is 4!

The table shows a schedule of inga’s payment plan for a car. inga’s payment plan for the first 3 years year balance monthly payment end of year balance 1 $19,691.28 $273.49 $16,409.40 2 $16,409.40 $273.49 $13,127.52 3 $13,127.52 $273.49 $9,845.64 how many more years will it take inga to pay off the loan? 2 years. 3 years 4 years 6 years

Answers

Inga needs 3 more years to pay off the whole amount.

What is the monthly payment?

A portion of the monthly payment is called the principal, which is the original amount borrowed.

First year balance = $19,691.28

Monthly payment = $273.49

Annual payment = 273.49×12 = $3281.88

Remaining balance after 1 year = 19,691.28 - 3281.88 = $16,409,4

After 3 years balance = $9845.64

Remaining balance after payment (4 years) = 9845.64-3281.88 = $6563.76

Remaining balance after payment (5 years)  = 6563.76-3281.99  = 3281.88

Remaining balance after payment (6 years) =3281.88-3281.88  = 0

Hence, Inga needs 3 more years to pay off the whole amount.

In HPE and GKJ, Which of the following would be enough to prove FPH ~ JKG?

Answers

Answer: Choice D

[tex]\frac{KJ}{JG} = \frac{PF}{FH}[/tex]

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

Explanation:

Refer to the drawing below. I started off with the original diagram given, then I split up the triangles HPF (red)  and GKJ (blue)

We're given that [tex]\angle GJK \cong \angle HFP[/tex]. If we had another congruent pair of angles, then we could use the AA (angle angle) similarity theorem to prove the triangles are similar. However, none of the answer choices mention another pair of congruent angles. Choices A and B are very close, but the [tex]\sim[/tex] should be [tex]\cong[/tex] instead. So we rule them out.

Focus on triangle GJK. Notice how the sides KJ and JG are surrounding the angle GJK. In other words, angle GJK is sandwiched between sides KJ and JG. Similarly, angle HFP is sandwiched between sides PF and FH in triangle HFP.

If we knew that the ratios KJ/JG and PF/FH were the same, then that would be enough info to use the SAS (side angle side) similarity theorem to prove the triangles similar. So that's why we go for [tex]\frac{KJ}{JG} = \frac{PF}{FH}[/tex]

There are other possible ways to write that equation.
