Answer:

y = 15∠abc = 68°∠bac = 78°∠acb = 34°

Step-by-step explanation:

It is helpful to realize that the exterior angle is equal to the sum of the remote interior angles:

  146° = (5y+3)° +(4y+8)°

  135 = 9y . . . . . . . . . . . . . . divide by °, subtract 11

  15 = y . . . . . . . . . divide by 9

∠abc = (4y+8)° = (4·15 +8)° = 68°

∠bac = (5y+3)° = (5·15 +3)° = 78°

∠acb = 180° -146° = 34°

The students at Norton School were asked to name their favorite type of pet. Of the 430ilar results, about students surveyed, 258 said that their favorite type of pet was a dog. Suppose that only 100 students were surveyed, with similar results about how many students would say that a dog is their favorite types of pet?

Answers

Answer: 60

Step-by-step explanation:

From the question, we are informed that 430 students were surveyed and 258 said that their favorite type of pet was a dog. The fraction/decimal of those that chose dog as their favorite pet will be:

= 258/430

= 3/5

= 0.6

Suppose that only 100 students were surveyed, the number of students that would say that a dog is their favorite types of pet will be:

= 0.6 × 100

= 60

Answers

Answer:23

Step-by-step explanation:

If LP = 15 and PR = 9, find LR. Explain. LR = 24 because 15 + 9 = 24 according to the addition property of equality. LR = 6 because LR + LP = PR according to the Segment Addition Postulate, and 6 + 9 = 15 using substitution. LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution. LR = 6 because 15 − 9 = 6 according to the subtraction property of equality.

Answers

Step-by-step explanation:

Given,

LP = 15, PR = 9

Point P lies on the line segment PR. It would mean that,

LP + PR = LR

⇒LR = 15 + 9

⇒ LR = 24

Hence, "LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution" is the correct option.

Caitlyn spends $17 at the store. She buys a mop for $5 and 3 bottles of floor cleaner. If x represents the cost of each bottle of cleaner, the equation that can be used to find the value of x is 3 x + 5 = 17. Which shows the first step that should be taken to verify that $4 is the solution to the equation?
3 (4) minus 5 = 17
3 (4) = 17 + 4
3 (4) + 5 = 17 + 5
3 (4) + 5 = 17

Answers

Answer:

3(4) + 5 = 17

Step-by-step explanation:

Caitlyn spends $17. Buys mop for $5 and 3 floor cleaner. x=cleaner

3x + 5 = 17

3(4) + 5 = 17

12 + 5 = 17

17 = 17 (true)

What direction will the parent graph move if... f(x - 6) = (x - 6)

Answers

Going from f(x) = x to g(x) = f(x-6) = x-6 will move the graph 6 units to the right.

Effectively replacing x with x-6 shifts the xy axis 6 units to the left, giving the illusion the function curve shifts 6 units to the right.

Answer: shifts 6 units to the right.
