Answer: (1, 10)

Step-by-step explanation:

When you translate, you add or subtract the value you are moving to each coordinate

(6,7) left 5 would be -5 to the x coordinate and 3 up would be +3 to the y coordinate.

6-5=1

7+3=10

new point is (1,10)

moving left 5 units is subtracting 5 from the x value:

6-5 = 1

Moving up 3 units is adding 3 to the y value:

7 + 3 = 10

The answer is (1,10)

The hypotenuse of a certain triangle is 5 units long and one leg is 3 units long

[tex]3^{2} +b^{2} =5^{2}[/tex]

[tex]9+b^{2} =25[/tex]

You have a jar of Marbles in front of you 2 are Cordovan, 9 are yellow, 3 are white and 7 are red. What is the probability, as a fraction of selecting a marble that is white or yellow, followed by a marble that is Cordovan?​

Answers

Answer:

2/35

Step-by-step explanation:

Assuming that this is without replacement,

The total amount of marbles is 2+9+3+7, or 21.

9 are yellow, 3 are white. this makes 12.

The probability of selecting a white or yellow marble is 12/21.

Now without replacement (comment if it is with replacement.), there are 20 marbles left, and 2 are Cordovan. This means there is a 2/20 chance then of picking a Cordovan marble.

After multiplying the fractions we get

(12/21) * (2/20) = 2/35.

There is a 2/35 chance of selecting a yellow or white, then a cordovan marble.

Divide. Write your answer as a proper fraction, a whole number, or a mixed number 5÷7=​

Answers

Answer:

5/7

Step-by-step explanation:

Reason why is because when you're dividing, the second number gets flipped around.  For example, the 7 becomes 1/7 and instead of dividing, it becomes 5x1/7, which equals 5/7! Hope this helps

Because Aaron, age 32, is a smoker, he must pay more for life insurance. Given that Company A charges 20% more for smokers, Company B charges 18% more for smokers, Company C charge 25% more for smokers and Company D charges 15% more for smokers, Aaron decides to buy his $250,000 policy from Company B. Which of the following statements is true? A 5-column table with 3 rows titled Annual Insurance Premiums (per 1,000 dollars of face value) 10 year term. Column 1 is labeled age with entries 30, 31, 32. Column 2 is labeled Company A with entries 1.30, 1.57, 1.86. Column 3 is labeled Company B with entries 1.29, 1.55, 1.86. Column 4 is labeled Company C with entries 1.40, 1.64, 2.07. Column 5 is labeled Company D with entries 1.49, 1.88, 2.25. a. Aaron is paying the smallest premium possible with Company B. b. Aaron is paying $93 more in premiums than he would with Company A. c. Aaron is paying $129 more in premiums than he would with Company C. d. Aaron could have chosen any company because the premiums are all the same.

Answers

Answer:

d. Aaron could have chosen any company because the premiums are all the same.

Step-by-step explanation:

Going by the age of Aaron and the percentages charged by the various company due to smoking, it is safe to conclude that, the premiums are all the same. This could be seen in the table of column and rows which shows the annual insurance premiums (per 1,000 dollars of face value) over a 10 years term. The variation helps to show that, when the premium is evaluated, the are all the same.

Answer:

x = 27, y = 74

Step-by-step explanation:

Hi again :)

Since the angles of 5x + 4 and the one adjacent to x = 14 are corresponding angles, they are equal. That means that (5x + 4) + (x + 14) = 180 degrees.

5x + 4 + x + 14 = 180

6x + 18 = 180

6x = 162

x = 27

Also, the angle (5x + 4) and (2y - 9) are vertical angles, they are equal in value. We know the value of x now, so we'll substitute that in and solve for y.

5(27) + 4 = 2y - 9

135 + 4 = 2y - 9

139 = 2y - 9

148 = 2y

y = 74

As always, lmk if you have questions.

In the figure, the angles are formed by a transversal and two parallel lines. Which angles are congruent?

Answers

Answer:

A is your correct answer.

1, 3, 5, and 7 are equal to each other and 2, 4, 6, and 8 are equal to each other.

Step-by-step explanation:

Congruent angles are angles that have the same measure. In this example, where two parallel lines are cut by a transversal line, the angles in the same position on the top line and bottom line are congruent. For example, angle 1 and 5 are in the same position, so they have the same measure.

Also, vertical angles (opposite angles, like 5 & 7 in your example) have the same measure.

Step-by-step explanation:

The value is increasing exponentially with a growth factor of 1.023, so it will be ...

  v(t) = 192,300×1.023^t

  v(10) = 192,300×1.023^10 ≈ 241,399.09

The value is predicted to be $241,399.09 in 10 years.

Discount 75%, Sale Price $74.75, Original Price-?

Answers

Answer:

You will pay $18.69 for a item

Step-by-step explanation:

if you buy an item at $74.75 with 75% discount, you will pay 74.75 - 56.0625 = 18.69 dollars.

Answer:

$299

Step-by-step explanation:

The discount is 75%, so the sale price represents 25% of the original price.

25% : $74.75

(multiply both sides by 4 to get 100%)

100% : $299

the ratio of boy to girls in a school 1s 5:7. if there are 780 students in the school, how many boys are in the school?

Answers

Answer:

325 boys

Step-by-step explanation:

The ratio 5:7 represents 5+7=12 students. If we were to proportionalize this ratio to 780 students, we would multiply the ratio by 65/65 since 780/12=65.

Therefore, you have (5*65)/(7*65)=325/455 as your ratio. This means that there are 325 boys in the school
