Answer:

1. 6 2. -5

Step-by-step explanation:

On negatives you add.

Answer:

6 for the first one, then -5 for the next one

Step-by-step explanation:

alright, first one.

starts from 0 on a number line and hops 4 right, add 4. [ positive is right, negative is left ]

0 + 4 = 4

coming from 4, to 6 on the left, so either add -6 or subtract 6, both work either way.

4 + (-6) = -2

finally, we land up on -2, and then 8 units to the right once again, which would be adding 8.

-2 + 8 = 6

so that would be 6.

second one, inverse means opposite. so they're asking for the opposite of positive 5, which is negative 5. (-5)

Mr. Patel’s house is 1,850 ft 2 . He tiles 30% of the house on the first day. He tiles 185 ft 2 each day after that. How many more days will it take Mr. Patel to finish tiling the house?

Answers

Step-by-step explanation:

Tile A $9.75

Tile BTiles are $11 per tile if fewer than 50 tiles are purchased. For 50 or more tiles, tiles are $9.50 per tile.

Tiles are purchased by the box

Tile C There are 24 tiles per box. Each box is $185.

Area finished on the first day= 1850 x 30% = 555 ft2
Days required to finish tiling the house = 555 / 185 = 3
Therefore, it will take 3 more days for Mr Patel to finish tiling the house.

A drawing of a sailboat was made useing a restangle and two right triangles, as shown. what is the area of the drawing f the sailboat in square centimeters

Answers

Answer:

45 centimeters squared (45 square centimeters - same thing)

Explanation:

First we need the area of each shape

To find the area of a right triangle we multiply the length of the legs and then divide by 2 - ab/2

Triangle 1: 6 centimeters squared

Triangle 2: 9 centimeters squared

To find the area of a rectangle you multiply the length by the width - lw

Rectangle: 30 centimeters squared

Now we add the values together:

6 + 9 + 30 = 45 centimeters squared

That is my answer, if you need anything else or more clarification I will edit this :)

Your answer would be 45 centimeters ^2

Answer:

31.5

Step-by-step explanation:

so first find the area of the triangle, which is 9. then divide that by 2 which equals 4.5.

now find the area of the missing square, which is 5×4, and that equals 20. now pretend that the square is whole, and find the area of the whole square. that would be 8×7, which equals 56. so now you need to subtract 4.5 and 20 from 56.
