Calculate the product 45.67x32.58 rounded to the nearest penny
serg [7]

We assume the monetary amount is a number such that the hundredths place represents a penny. (It's not billions of dollars, for example.)

45.67×32.58 = 1,487.9286 ≈ 1,487.93

_____

Any calculator can give you the product. Most will round the number for you if you specify a 2 decimal digit display.

The thousandths digit of the product (8) is more than 4, so the hundredths digit (2) is increased by 1 (to 3) as the digits to its right are dropped.

Multiple Choice Suppose y varies directly as x. if y = 5 when x=8, find y when x=64
Juliette [100K]

Answer:

Step-by-step explanation:

y∞x

then

y=kx (with k as constant)

y=5 when x=8

⇒Putting this in the first equation

⇒5=k×8

⇒k=5/8

Now

y=? when x=64

Putting x=64 in the first equation

y=kx

⇒y=(5/8)×64

We get

y=40

Hope u understand

Solve for g.<br> -3+5+6g=11-3g−3+5+6g=11−3g
PtichkaEL [24]

Answer: \mathrm{No\:Solution}

Step-by-step explanation:

\begin{bmatrix}-3+5+6g=1\\ 1-3g+5+6g=11-3g\end{bmatrix}

\begin{bmatrix}1-3\left(-\frac{1}{6}\right)+5+6\left(-\frac{1}{6}\right)=11-3\left(-\frac{1}{6}\right)\end{bmatrix}

\begin{bmatrix}\frac{11}{2}=\frac{23}{2}\end{bmatrix}

\frac{11}{2}=\frac{23}{2}\:\mathrm{\:is\:false,\:therefore\:the\:system\:of\:equations\:has\:no\:solution}
