Does Anyone Know What I Am Missing To Get The Final Mark? Any Ideas Would Be Much Appreciated :)

Answers

Answer 1

Answer: Isosceles

Step-by-step explanation:

Given: AB || DE ,  BC is a transversal

∠ABC ≅ ∠BCE by Alternate Interior Angles Theorem --> ∠BCE = 80°

∠DCA, ∠ACB, & ∠BCA are supplementary  --> ∠ACB = 50°

By the Triangle Sum Theorem, ∠A+∠B+∠C  = 180° --> ∠CAB = 50°

Triangle is isosceles because ∠A ≅ ∠C

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100

Answers

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

2 over 8 equals j over 18

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

2 over 8 equals j over 18

Draw a Letter figure and translate it 3 units to the right, reflect in the y axis and rotate it 100

Can someone help do this plz

Answers

Answer:

We need to know what the letter is and where it was originally. Also is the 100 one hundred degrees or one hundred coordinates?

Step-by-step explanation:

1. For the translating part, simply pick one of the coordinates and move it three spaces to the right. Do this for each point.

2. For the reflecting part, count how many spaces each coordinate is from the y-axis, or vertical line. For the sake of example, let's say it is 3 spaces from the y-axis and started in the top left grid, or Quadrant III. You would then move said coordinate 3 spaces to the right in Quadrant IV, which is the top right.

I can't really help you on the rotating, since I don't know what form the 100 is in, but I hope this helped!

Find the diameter of a circle if its circumference is 53.38 inches. Use π ≈ 3.14. Round to the nearest hundredth

Answers

Answer:16.9

Step-by-step explanation:

We know that the formula for C= πd. So to find the diameter of a circle we work backwards from its circumference. Division is the opposite of multiplying, so we divide its circumference by π: 53.38 / 3.14 = 17. To fully check: C= πd = π(17) = 53.38. The diameter is 17 inches. Hope this helps!
