Multiply: 0.063 x – 0.0096=

Ahat [919]

Answer:

-0.0006048

Explanation:

Given the expression:

$0.063\times-0.0096$

We can write the expression in the form below:

$=\frac{63}{1,000}\times-\frac{96}{10,000}$

Next, we simplify the result.

$\begin{gathered} =\frac{-63\times96}{1,000\times10,000} \\ =-\frac{6048}{10.000,000} \\ =-0.0006048 \end{gathered}$

Therefore:

$0.063\times-0.0096=-0.0006048$

A pole that is 3.3 meters tall casts a shadow that is 1.36 meters long. At the same time, a nearby building casts a shadow that

My name is Ann [436]

Answer:

Height of building is 115.86 m.

Step-by-step explanation:

This is problem of proportion.

a:b = c:d

____________________________________________________________

height of pole = 3.3 m

length of shadow of pole = 1.36 m

ratio

height of pole: length of shadow of pole = 3.3 : 1.36

________________________________________________

let the height of building= x m

length of shadow of building= 47.75 m

ratio

height of building: length of shadow of building= x: 47.75

ratio in both the cases will be same

thus,

x/47.75 = 3.3 / 1.36

=> x = 3.3 / 1.36 * 47.75 = 115.86

Thus, height of building is 115.86 m.

10) What is the solution to the system of equations shown below?

kkurt [141]

Answer:

X= 7.5

Y= -5

Step-by-step explanation:

In systems of equations, the goal is to add both of the equations together so it cancels one of the variables and you solve for that variable. Before you add they together, you multiply one of the equations by a negative number so when you add them together one of the numbers with x or y cancel.
