Answer:

mass=180kg and the volume=6m³.

then the formula to find density is= mass/volume

using this formula,180kg/6m³=30kg/m³

Answer:

8 m³

Step-by-step explanation:

Let v represent the volume.  Recall that density is mass/volume, which here is 0.9 kg/m³.  To find the volume of this object, divide the density into the mass:

 7.2 kg

--------------- = 8 m³

0.9 kg/m³

Answer:

D) 150 miles.

Step-by-step explanation:

The computation is shown below:

Given that

The Cost of  the car rental agency of A is $50 + 0.10 per mile

The Cost of  the car rental agency of B is $20 + 0.30 per mile

Here we assume the per mile be x

Now we equate these equations

SO,

$50 + 0.10x = $20 + 0.30x

$30 = 0.20x

x = 150

SO it would be more than 150 miles

Answer:

I got x=10

Step-by-step explanation:

Step 1

Everything must add up to 180

180= 6x - 6 + 7x + 1 +55

Step 2

Combine everything

6x + 7x = 13x

-6 + 1 +55 =50

180 = 13x + 50

Step 4

Subtract. 180 -50

130 = 13x

Step 5

Divide 130/13

X=10

6(10) -6 = 54

7(10) + 1=71

Answer:

Triangle BDE and triangle BAC are similar triangles

Hence, two lines DE and AC are parallel to each other

Step-by-step explanation:

For proving that DE is parallel to AC, we are required to prove that triangle BDE and triangle BAC are similar triangles

The ratio of sides of both the triangle must be equal to each other

Hence

[tex]\frac{BE}{DB} = \frac{BC}{BA} \\\frac{16.1}{28} = \frac{20.7+16.1}{64}\\0.575 = 0.575[/tex]

and angle B is common.

Hence the two triangles are similar.

Therefore angle BDE and angle BAC are equal like wise angle BED and angle BCA are equal.

Thus, the two lines DE and AC are parallel to each other

Answer:

[tex](a)\ k_2 = 1in:3ft[/tex]

[tex](b)\ Scale\ width =\frac{16}{3}\ in[/tex]

Step-by-step explanation:

Given

[tex]k_1 = 1in : 2ft[/tex] --- Initial scale factor

[tex]Blueprint: 12in\ by\ 8in[/tex] --- Missing from the question

Solving (a): The new scale factor.

Convert the initial blueprint to actual measurement using the initial scale factor, we have:

[tex]Length = 12 * 2ft = 24ft[/tex]

[tex]Width = 8 * 2ft = 16ft[/tex]

From the question, we understand the new scale factor represents the width as 8in.

The scale factor (k2) is then calculated as:

[tex]k_2 = \frac{Scale\ length}{Actual\ length}[/tex]

[tex]k_2 = \frac{8in}{24ft}[/tex]

Simplify

[tex]k_2 = \frac{1in}{3ft}[/tex]

Represent as fraction

[tex]k_2 = 1in:3ft[/tex]

The above is the new scale factor

 Solving (b): The new width

Using the scale factor above we have:

[tex]k_2 = \frac{Scale\ width}{Actual\ width}[/tex]

[tex]\frac{1in}{3ft} = \frac{Scale\ width}{16ft}[/tex]

The 16 is gotten from:

[tex]Width = 8 * 2ft = 16ft[/tex]

So, we have:

[tex]Scale\ width = 16ft * \frac{1in}{3ft}[/tex]

[tex]Scale\ width = 16 * \frac{1in}{3}[/tex]

[tex]Scale\ width =\frac{16\ in}{3}[/tex]

[tex]Scale\ width =\frac{16}{3}\ in[/tex]

Hence, the scale width of the blueprint is: 16/3 inches

Answer:

[tex]2 + 3 + 7 + x = 4 \times 5 \\ x = 20 - 12 = 8[/tex]

Answer:

1. (5x - 2) + (2x - 2) + x = [tex]180^{o}[/tex]

2. m<J = [tex]113^{o}[/tex]

3. m<K = [tex]44^{o}[/tex]

4. m<L = [tex]23^{o}[/tex]

Step-by-step explanation:

Generally, the sum of angles in a triangle = [tex]180^{o}[/tex].

So that;

m<J + m<K + m<L = [tex]180^{o}[/tex]

(5x - 2) + (2x - 2) + x = [tex]180^{o}[/tex]

5x + 2x + x -2 -2 = [tex]180^{o}[/tex]

8x - 4 = [tex]180^{o}[/tex]

8x = [tex]180^{o}[/tex] + 4

8x = 184

x = [tex]\frac{184}{8}[/tex]

x = [tex]23^{o}[/tex]

Thus,

m<J = (5x - 2)

       = 5(23) - 2

       = [tex]113^{o}[/tex]

m<K = (2x -2)

        = 2(23) - 2

        = [tex]44^{o}[/tex]

m<L = x

       = [tex]23^{o}[/tex]

Answer:

3 1/3 = 10/3

0.3 = 3/10

a * 1/a =1

then 1/a is multiplicative inverse of a

0.3* 3 1/3 = 3/10 * 10/3 =1

0.3 is multiplicative inverse of 3 1/3

Step-by-step explanation:

Answer:

3 1/3 = 10/3

10.3 = 0.3 = 3 1/3

x * 1/x = 1

∴ yes, the multiplicative reverse of 3 1/3 is 0.3

Answer:

28.56

Step-by-step explanation:

First we need to calculate the mean average of the numbers

Average = 112+89+95+77+103/5

Average = 476/5

Average = 95.2

If Sam made 30% of goals in his last 6 games, then on average, amount made is expressed as;

Average of the last six games = 30% of 95.3

Average of the last six games  = 0.3 * 95.2

Average of the last six games = 28.56

Hence the required point average is 28.56

Answer: A and C

Step-by-step explanation:

The line which is perpendicular to 2x + 14y = 70 mus have a slope of 7/2.

A linear function is in the form:

y = mx + b

Where m is the slope and b is the y intercept

Two lines are perpendicular if the product of there slope is -1

Given the line:

2x + 14y = 70

14y = -2x + 70

y = (-2/7)x + 70

The line which is perpendicular to 2x + 14y = 70 mus have a slope of 7/2.

--------------

   4 hrs

It is not necessary to perform the indicated division.  Just multiply this unit rate by '8 hours':

5 pages

-------------- * 8 hrs = 10 pages
