5 0

Answer:12 5/8

Step-by-step explanation:

Add the whole numbers together. 3 + 9 = 12

Multiply 1/4 so that it will have the same dnominator as 3/8. 2(1/4)= 2/8

Add the fractions together. 2/8 + 3/8 = 5/8.

Add the whole number and fraction to get a mixed number. 12 + 5/8 = 12 5/8

Best Buy is giving you a free t.v. with purchase of a new refrigerator. The t.v. is 30 inches tall and 48 inches wide. How big i
user100 [1]

Answer:

57 inches

Step-by-step explanation:

The height, width, and diagonal of the TV screen form a right triangle.

Use the pythagorean theorem, a² + b² = c², and solve for c, the hypotenuse/diagonal of the TV.

a² + b² = c²

30² + 48² = c²

900 + 2304 = c²

3204 = c²

56.6 = c

Round this to the nearest inch:

56.6

= 57

So, the diagonal of the TV screen is 57 inches

A chef draws cookies randomly from a box containing 6 cookies of the same shape and size. There is 1 chocolate cookie, 3 almond
vovangra [49]

Answer:

1/5

Step-by-step explanation:

The probability of drawing an almond cookie the first time is 3/6=1/2, since there are a total of 6 cookies and 3 of them are almond. However, the second time the chance is 2/5, since there are 5 cookies left and only two of them are almond. The equation to model this is therefore:

P=\dfrac{1}{2}\cdot \dfrac{2}{5}=\dfrac{1}{5}

Hope this helps!
