34kurt

Answer: The answer is 90.

Step-by-step explanation: This is because if you cut the shape horozontaly than it is going to be seperated and the equation will looks like this:

(6 x 9) + (6 x 6)

Find the areas of the figures below. Show all work on for each problem.
Marysya12 [62]

Answer:  A = ≈28.55 cm²

Step-by-step explanation:

It is drawn as if it should be a triangle minus a rectangle with an area of

½(10)(13) - (7)(6) = 23 cm²

However it is not to scale.

The angle on the right side is

θ = arctan10/13 = 37.56859...°

Meaning the right triangle has a height of

h = 4tan37.56859 = 3.07692 cm

So the right triangle has an area of

Ar = ½(3.07692)(4) = 6.15384... cm²

The left hand side consists of a triangle over a rectangle

The height of the triangle is 4, the base is is 4/tan37.56859 = 5.2 cm

so the left area is

(2)(6) + ½(5.2)(4) = 22.4 cm²

So the sum of the areas of the two enclosed shapes is

A = 22.4 + 6.15384... = 28.55384... ≈28.55 cm²

Margo lists the sizes, inches, of set of screws: 9/64, 5/32, 1/16, 1/8. She reasons that because the denominators are in order f
Finger [1]

Answer:

I think she is incorrect she need to change all the fractions to the same denominators

Step-by-step explanation:

We are going to change all the fractions to 64

9/64 stays the same

5/32 multiply 2    then 10/64

1/16 multiply by 4 then 4/64

1/8 multiply by 8  then 8/64

Now we can order then

5/32 > 9/64 > 1/8 > 1/16 This is the right order

She was wrong.

Jon places a dot on a coordinate plane at (-10, -4). He wants to place another dot across the y axis, and it must be 14 points a
bazaltina [42]
At (4,-4). Because, the first value is the horizontal x-coordinate and the second is the vertical y-coordinate, so the direction of going across the y-axis is a horizontal movement. Therefore, you must add 14 to the x-coordinate. You add because positive is the opposite direction of the your first x-coordinate, -10. So the answer is (4,-4).
