lyudmila [28]3 years ago

Answer:

8 dollar/hr

Step-by-step explanation:

she worked 2 1/2 hrs yesterday and 4 1/4 hrs today

2 1/2 + 4/14

2+4 is 6

and 1/2+1/4 multiply 2 to both numerator and denominator of  1/2 so that the denominator of both fraction is like

it will now become 2/4+1/4 which equals 3/4

This means that she worked total of 6 3/4 hour in all yesterday and today

she is paid 54 dollar

we will need to divide 6 3/4  or written as 6.75 by 54 to find how much she earns per hour

and that would be 8

so she earns 8 dollar per hour.

Which statement describes whether a right triangle can be formed using one side length from each of these squares?
balu736 [363]

Answer:

Step-by-step explanation:

The area of the given squares are

Area = 64 in

Area = 225 in

Area = 289 in

The length of each side of a square is determined by finding the square root of its area. For the first square, the length of its side is √64 = 8inches. For the second square, the length of its side is √225 = 15inches. For the third square, the length of its side is √289 = 17inches.

For a right angle triangle to be formed, Pythagorean theorem must be obeyed. Sum of the square of the smaller sides must equal the square of the longer side. Therefore,

8² + 15² = 17²

289 = 289

Therefore, the correct statement is

Yes, a right triangle can be formed because the sum of the areas of the two smaller squares equals the area of the largest square

If sin (x-3)° = cos (2x + 6)°, then what is the value of x?
Travka [436]

Answer:

if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.

----------

Note: sin and cos are complementary functions....

sin(x) = cos (90-x)

-------------------

Your Problem:

sin(x-3) = cos(90-(x-3))

Equation:

90-[x-3] = 2x+6

90-x+3 = 2x+6

3x = 93-6

x = 31-2

x = 29
