D. 2 11/16

Answers

If you would like to know how many tortes are left, you can calculate this using the following steps:

five chocolate tortes - 2 5/16 tortes = 5 - 2 5/16 = 5 - 37/16 =  80/16 - 37/16 = 43/16 = 2 11/16

The correct result would be D. 2 11/16.

Number of left tortes are, 43/16

We have to given that,

A chef prepared five chocolate tortes for a dinner party.

And, The guests consumed 2 5/16 tortes.

Now, Number of left tortes are,

⇒ 5 - 2 5/16

⇒ 5 - 37/16

⇒ (80 - 37) / 16

⇒ 43/16

Therefore, Number of left tortes are, 43/16

The product of 7/16, 4/3, and 1/2 isa. 7/12.
b. 7/24.
c. 21/32.
d. 2 13/48.

Answers

If you would like to know how much is the product of 7/16,4/3, and 1/2, you can calculate this using the following steps:

7/16 * 4/3 * 1/2 = 7/24

The correct result would be b. 7/24.
(7)/(16) *  (4)/(3) *  (1)/(2)  =  (7* 4* 1)/(16* 3* 2)=(7* 4)/(4* 4* 3* 2)=(7)/(4* 3* 2)\n\n =(7)/(12*2) =\boxed{\bf{(7)/(24)}}

Your answer is B. 7/24.

Write 22.056 in an expanded form

Answers

We know the first place after decimal is tenths

The second place after decimal is hundredths

The third place after decimal is the thousandths place

So for 0.056

0 is at the tenths place

5 is at the hundredths place

and 6 is at the thousandths place

Expanding 22.056 we get

22.056 = 20 + 2 + 0.05 + 0.006

OR

22.056 = 20+2+(5)/(100)+(6)/(1000)


20.000 + 2.000 + .050 +.006

What are the solutions to the equation 9x2 = 49, rounded to the nearest tenth?A.

D.
21, –21

Answers

A.
2.3, –2.3

Working;

9x^(2) =49
x^(2) = (49)/(9)
x=\sqrt{ (49)/(9) }
x= +-2.3
I would go for A if anything
