Answer:

One ml is equal to a cm3, then

m=2.67g/cm3*30.5cm3

m=81.435g

If we divide this quantity by 1000 to pass this to Kg we get:

m=81.435/1000=0.081435kg

Step-by-step explanation:

Remember the formula of density is density=mass/volume, if we solve for mass we get:

mass=density*volume

Question 3
C(1, -7) D(-8, -7)
To find side length DC you count how many units are between the two points. C(1) D(-8) = 9 units

Question 1
Again count the points around the edge of the square. Since this shape is a rectangle, side length WX = YZ and side length XY = WZ.
WX = YZ = 11 units
XY = WZ = 15 units
Perimeter = WX + YZ + XY + WZ = 11(2) + 15(2) = 52 units

The packaging lists a model airplane’s length as 10.5 in. It also gives the scale as 1:83. What is the length of the actual airp

Kruka [31]

Since the scale is 1:83, the real airplane is 83 times longer than the model airplane.

real length = 10.5 in * 83 = 871.5 in

Now we convert 871.5 in into ft.
1 ft = 12 in, so 1 in = 1/12 ft
We divide the number of inches by 12 to find the number of feet.

871.5 in = 871.5/12 ft = 72.625 ft

Consider the quadratic equation x 2 = 4x - 5. How many solutions does the equation hase?

lara [203]

Answer:

The equation has 2 non real solutions.

Step-by-step explanation:

Given:

$x ^2 = 4x - 5$

To Find:

The solutions of the equation = ?

Solution:

Lets find the solution using the quadratic equation formula

$x ^2 = 4x - 5$

$x^2-4x +5 = 0$

$x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$

Here

a = 1

b =-4

c = 5

Now Substituting the values,

$x = \frac{-(-4) \pm \sqrt{(-4)^2-4(1)(5)}}{2(1)}$

$x = \frac{4\pm \sqrt{16-20}}{2}$

$x = \frac{4\pm \sqrt{-4}}{2}$

$x = \frac{4\pm \sqrt{4}\times \sqrt{-1}}{2}$

$x = \frac{4\pm 2 \sqrt{-1}}{2}$

$x = \frac{4\pm 2i}{2}$

$x= \frac{4+2i}{2}$ $x= \frac{4-2i}{2}$

x= 2 + i x= 2-i

A rectangular picture measures 6 inches by 8 inches. Simon wants to build a wooden frame for the picture so that the framed pict

dangina [55]

Answer:

$4x^2 + 28x - 52 \leq 0$

Where, x ≥ 0

Step-by-step explanation:

Given,

The rectangular picture has,

Length = 6 inches,

Width = 8 inches,

Suppose x be the width( in inch ) of the piece of wooden,

After joining the piece,

New length = 6 + 2x ,

New width = 8 + 2x

So, the area of the final figure,

$V=length\times width = (6+2x)(8+2x)$

According to the question,

V ≤ 100 inch²

$\implies (6+2x)(8+2x)\leq 100$

$48 + 12x + 16x + 4x^2\leq 100$

$4x^2 + 28x + 48 - 100\leq 0$

$4x^2 + 28x - 52 \leq 0$

But, width can not be negative,

i.e. x ≥ 0

The graph shows the relationship between the amount of change given from a $10 bill and the number of bagels purchased.

Soloha48 [4]

The graph is a linear graph

The equation of a linear graph is given in the form $y=mx+c$ where $m$ is the gradient and $c$ is the y-intercept

To find gradient:
Choose any two coordinates that lie on the line.
We choose (4,7) and (0, 10)
$m= \frac{ y_{1}- y_{0}}{ x_{1}- x_{0} }$
$m= \frac{10-7}{0-4} =- \frac{3}{4}$

the graph crosses the y-axis at 10, so the value of $c=10$

Forming the equation
$y=- \frac{3}{4} +10$
