The error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.

The SSA congruence theorem only exist and holds true, only if the congruence non-included angles in both triangles are either obtuse or right angles and have two pairs of congruent sides.

Thus:

The two triangles given have a pair of non-included congruent angles that are less than 90 degrees.

Therefore, the error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.

Answer:

the first one i think is a reflection over the x-axis

for the last on question 9 A, I think  it's a 90-degree rotation counterclockwise

your coordinates for part B on would be -4,7 and -6,13

and then for part B on the last question, i think your coordinates would be -5,4

Step-by-step explanation:

Answer:

So the sum of a triangle is 180° so 45°+27°= 72°

180° - 72°= 108°

X = 108°

2,600 crayons

Step-by-step explanation:

10 boxes in a carton

5 cartons

10x5=50

52 crayons in a box

52x10=2,600 crayons

:)

Answer:

2,600

Step-by-step explanation:

If there are 52 crayons in a box, and 10 boxes in each carton, we know that there are 520 crayons in one carton. (52 x 10) If Mr. Johnson ordered 5 cartons,

520 x 5= 2,600. So, he would get 2,600 crayons.

Answer:

Step-by-step explanation:

First table:(left)

(1, 15) (2, 30)

(30 - 15)/(2 - 1) = 15/1 = 15

y - 15 = 15(x - 1)

y - 15 = 15x - 15

y = 15x

Second table:(right)

(0, 10)  (1, 25)

(25 - 10)/(1 - 0)= 15/1= 15

y - 10 = 15(x - 0)

y - 10 = 15x - 0

y = 15x + 10

Answer:

3/10 of people vacationed in another state.

Step-by-step explanation:

Because there are 60 people in total, the denominator has to be 60. The numerator then is going to be the amount of people that vacationed in another state. Simplify that fraction by 6, and you will get 3/10 as your answer.

Answer:

[tex]\frac{3}{10}[/tex]

Step-by-step explanation:

Since we want a fraction, we find the total number of people who vaccinated, then we find how many people vacationed in another state.

18+10+5+15+12=60, and 18 people vacationed in another state, we get

[tex]\frac{18}{60}[/tex], and we can divide top and bottom by 2, we simplify to [tex]\frac{3}{10}[/tex]

Answer:

2 1/4 square yards

Step-by-step explanation:

We have been given that Matthew and his 3 siblings are weeding a flower bed with an area of 9 square yards.    

All person weeding flower bed: .

To find the area in square yards weeded by each child, we will divide total area of flower bed by 4.

Therefore, each child weeded  square yards of flower bed.

Answer:

I believe it's going to be2 1/4 square feet

Answer:

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angle.

146° is an exterior angle of the triangle, then

5y + 3 + 4y + 8 = 146

9y + 11 = 146 ( subtract 11 from both sides )

9y = 135 ( divide both sides by 9 )

y = 15

Then

∠ A = 5y + 3 = 5(15) + 3 = 75 + 3 = 78°

∠ B = 4y + 8 = 4(15) + 8 = 60 + 8 = 68°

∠ C = 180° - (78 + 68)° ← sum of angles in triangle = 180°

∠ C = 180° - 146° = 34°

The probability of the family having two dogs or two cats is 1/2 or 50%.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

The theoretical probability of the family having two dogs or two cats can be calculated as follows:

P(D) be the probability of having a dog

P(C) be the probability of having a cat.

Since the family has an equally likely chance of having a cat or a dog, we have:

P(D) = 1/2 and P(C) = 1/2

The probability of having 2 dogs is:

P(D) x P(D) = (1/2) x (1/2) = 1/4

The probability of having 2 cats is:

P(C) x P(C) = (1/2) x (1/2) = 1/4

The theoretical probability of the family having two dogs or two cats is:

P(2 dogs or 2 cats).

= P(2 dogs) + P(2 cats)

= 1/4 + 1/4

= 1/2

Thus,

The probability of the family having two dogs or two cats is 1/2 or 50%.

Answer:

x = 4

Step-by-step explanation:

x + 6 +2x = 2x + 6 + 4

combine like terms:

3x + 6 = 2x + 6 + 4

add numbers:

3x + 6 = 2x + 10

subtract 6 on both sides:

3x + 6 - 6 = 2x + 10 - 6

3x = 2x + 4

subtract 2x from both sides:

3x - 2x = 2x - 2x + 4

x = 4

short explanation:

if you look at the equation, both sides have 6 and 2x which would cancel each other out. That would leave x = 4

I believe (x+5)(x-2) would be equal though.

Step-by-step explanation:

(x-5)(x+2) = x²+2x-5x-10

simplify:

x²-3x-10 ≠ x²+3x-10

(x)(x+3) = x²+3x

simplify:

x²-3x ≠ x²+3x-10

(x+3)(x-10) = x²-10x+3x-30

simplify:

x²-7x-30 ≠ x²+3x-10
