A bag of cookies weighs 19.1 ounces. The bag contains 50 cookies. How much does each cookie weigh?
saveliy_v [14]

Answer: 0.382 ounces

Step-by-step explanation:

To find the unit rate of the weight of a single cookie, we will use division.

        19.1 ounces per bag / 50 cookies in the bag = 0.382 ounces per cookie

To check our work, we will multiply 0.382 ounces per cookie by 50. Since the bag, with 50 cookies, weighs 19.1 ounces, 0.382 times 50 should equal about 19.1 ounces.

        0.382 ounces * 50 cookies = 19.1 ounces ✓

If x^2+25y^2=416 and x-5y=-16 the value of xy is <br><br> a)16<br> b)8<br> c)-8<br> d)-16
pshichka [43]

Answer:

(a)

Step-by-step explanation:

Note the expansion of (x - 5y)² is

(x - 5y)² = x² - 10xy + 25y² , that is

(x - 5y)² = x² + 25y² - 10xy ← substitute given values

(- 16)² = 416 - 10xy

256 = 416 - 10xy ( subtract 416 from both sides )

- 160 = - 10xy ( divide both sides by - 10 )

xy = 16 → (a)

The angle 01 is located in Quadrant I, and sin(01)=1/2 what is the value of cos(01)
vovikov84 [41]

Answer:

The value of Cos(01) is 0.866 or √3/2

Step-by-step explanation:

In this question, we are asked to calculate the value of cos (01) given the value of sin(01)

Now, given the value of sin (01), we can calculate the value of cos (01).

To get the value of 01, we simply find the value of the arc sin 01

Mathematically since sin (01) = 1/2

(01) = arc sin (1/2)

(01) = 30 degrees

Now since 01 = 30 degrees

cos 01 = Cos (30) = 0.8666 or simply √3/2

Please some help for question 1
o-na [289]

Answer:

f (3) is equal to 31

Step-by-step explanation:

f (3) means that x is equal to 3 [hence f (x) ---> f (3)]

Plugin 3 into all the x values to solve:

4(3)^2 - 2(3) + 1

4(9) - 6 + 1

36 - 6 + 1

30 + 1

31

f (3) is equal to 31
