Answer:

2,110

Step-by-step explanation:

5 • [(14 + 3 • 30) + 120] + 10³ – 10

The dot means multiplication

The we can use the order of BODMAS

First is open the brackets

5 • [(14 + 3 • 30) + 120] + 10³ – 10

5 • [(14 + 90) + 120] + 10³ – 10

5 • [104 + 120] + 10³ – 10

5 • 224 + 10³ – 10

1,120 +  10³ – 10

1,120 + 1000 - 10

2,120 - 10

Answer:

Opposite Angles Theorem

Step-by-step explanation:

All opposite angles are congruent, meaning that two angles created by intersecting lines that oppose eachother are equal in size. The theorem goes by different names, so I don't know exactly what your teacher is asking for, but I hope I could help.

Jaime has 5 over 11 spaceof a project completed while Tim has finished 7 over 13 spaceof the same project.
faust18 [17]

Answer:

a. Tim has completed a greater amount of work.

b. Together they have completed \frac{142}{143} part of two projects.

Step-by-step explanation:

Let us assume that the project on which Jaime and Tim are working has x amount of space.

Now, given that Jaime has 5 over 11 space of a project completed while Tim has finished 7 over 13 space of the same project.

Therefore, Jaime has completed \frac{5x}{11} amount of space and Tim has finished \frac{7x}{13} amount of space.

a. Now, (7x) \times 11 > (5x) \times 13

⇒ \frac{7x}{13} > \frac{5x}{11}

Therefore, Tim has completed the greater amount of work. (Answer)

b. Together they have completed (\frac{7x}{13} + \frac{5x}{11}) = \frac{(7 \times 11 + 5 \times 13)}{13 \times 11} x = \frac{142}{143}x amount of space out of 2x amount of space. (Answer)

Jaclyn gets a hit 40% of the time while playing softball. She is going to use colored tiles to simulate her chances of getting a
azamat

Answer:

18 red tiles

Step-by-step explanation:

One way to look at this problem would be to take the number of tiles that Jaclyn used to get a possibility of 40% hits.

Jaclyn put 12 green tiles, this represents the 40% of the hits that she could get.

Now we know that 12 = 40%

We need to find how many red tiles she should put to still keep the 12 green tiles as 40%. We can also assume that 12 red tiles would be another 40%.

So we have 12 red tiles currently.

Now we still have another 20% left.

Since 12 red tiles = 40%, we can assume that:

6 red tiles = 20% of the total.

So if we add both the 40% red tiles to the 20% red tiles we get:

12 + 6 = 18 red tiles.

So Jaclyn will have to put 18 red tiles and 12 green tiles to simulate her chances of getting a hit.
