Metallic silver has a density of 10.50. what is the mass, in g, of a silver ingot that is 28.0 cm long, 4.90 cm wide, and 3.60 c

frozen [14]

Answer:

5190 g

Step-by-step explanation:

Calculate the volume:

28.0 cm × 4.90 cm × 3.60 cm = 493.92 cm³

Density is mass divided by volume:

D = M / V

Solving for mass:

M = D V

Substituting values:

M = (10.50 g/cm³) (493.92 cm³)

M = 5186.16 g

Rounding to three significant figures, the mass is 5190 g.

The Baltimore Zoo feeds their elephants a combination of fruit and grass. The zookeeper would like to create a model to represen

Anika [276]

A function can be represented on a table and on a graph.

The models of the linear relationship between f(x) and x are:

$\mathbf{A.\ f(x) = 30x + 22}\\\mathbf{C.\ The\ table}\\\mathbf{F.\ The\ graph}$

The given parameters are:

$\mathbf{Start = 22}$

$\mathbf{Additional = 30}$

So, the function that models the linear relationship is:

$\mathbf{f(x) = Start + Additional \times x}$

Substitute known values

$\mathbf{f(x) = 22 + 30 \times x}$

Evaluate all products

$\mathbf{f(x) = 22 + 30x}$

Rewrite as:

$\mathbf{f(x) = 30x + 22}$

By comparing the above function to the list of options, we have the true options to be:

$\mathbf{A.\ f(x) = 30x + 22}\\\mathbf{C.\ The\ table}\\\mathbf{F.\ The\ graph}$

Mhanifa u helped me with this question.... U said it was 25 and its not so why is it wrong

Yanka [14]

Hey I don't know who Mhanifa is but 25 is correct, and I will put the entire explanation to how to get the answer here.

First of all the 2 lines on the left and right side of the triangles are means that those 2 lines are equal and thus forming a isosceles triangle.

This means that the bottom right angle is also 2x+2 degrees.

Now because all 3 angles in a triangle adds to 180 degrees, we can set up equation.

3x+1+2x+2+2x+2=180

Now combine like terms

7x+5=180

Then solve, first subtract 5 from both sides.

7x=175

Now divide 7 from both sides

x=25

X varies directly as y. If x is 9 when y is 4, find x when-y is 8.

jeka94

Answer:

see explanation

Step-by-step explanation:

Given x varies directly as y then the equation relating them is

x = ky ← k is the constant of variation

To find k use the condition x = 9 when y = 4

k = $\frac{x}{y}$ = $\frac{9}{4}$ = 2.25

x = 2.25y ← equation of variation

When y = 8, then

x = 2.25 × 8 = 18
