Answer:

Density of mixture is 7.0 g/[tex]cm^{3}[/tex].

Step-by-step explanation:

Density of mixture = density of water in the mixture + density of oil in the mixture

Given: water and oil were mixed in a ratio 3:5

           density of water is 1.0 g/[tex]cm^{3}[/tex] and that of oil is 0.8 g/[tex]cm^{3}[/tex].

Then,

density of water in the mixture = 3 x 1.0 g/[tex]cm^{3}[/tex]

                                   = 3.0 g/[tex]cm^{3}[/tex]

Density of the volume of water in the mixture is 3.0 g/[tex]cm^{3}[/tex].

density of oil in the mixture = 5 x 0.8 g/[tex]cm^{3}[/tex]

                                              = 4.0 g/[tex]cm^{3}[/tex]

Density of oil in the mixture is 3.0  g/[tex]cm^{3}[/tex].

So that,

Density of mixture = 3.0 + 4.0

                               = 7.0

Density of mixture is 7.0 g/[tex]cm^{3}[/tex].

Answer:

1. Josie needs 21 litres of fruit juice need 28 litres of lemonade.

2. Josie can make an extra of 35 litres of punch.

3. 5:8

Step-by-step explanation:

a) The ratio of the fruit juice to lemonade = 3:4

Total litres of punch to be made = 49

Amount of fruit juice needed = [tex]\frac{3}{7}[/tex] x 49

                                                 = 21 litres

Amount of lemonade needed = [tex]\frac{4}{7}[/tex] x 49

                                                  = 28 litres

Thus, she would need 21 litres of fruit juice need 28 litres of lemonade.

b) She has 15 litres of fruit juice left. Let the litres of punch to be made be represented by s.

[tex]\frac{3}{7}[/tex] x s = 15

s = 35

Josie can make an extra of 35 litres of punch.

c) For the second batch, she needs;

15 litres of fruit juice needs 20 litres of lemonade.

But adding 4 more litres to the lemonade makes the total litres of lemonade to be 24.

Thus the ratio of the juice to lemonade = 15:24

                                                                 = 5:8

Answer:

a = 2

b = -3

Step-by-step explanation:

Here, we want to solve the two equations simultaneously

since we have the same 5b term in both, we can subtract the second equation from the first

we have this as;

3a-2a = -9 -(-11)

a = -9+ 11 = 2

Recall;

2a + 5b = -11

2(2) + 5b = -11

5b = -11-4

5b = -15

b = -15/5

b = -3

Answer:

B.

Step-by-step explanation:

All you have to do is get the numbers from the triangle AUV and multiply them by 3/2.

12 * 3/2 = 18 [tex]\neq[/tex] 8

So we already know that the scale factor is not 3/2

It's 2/3 because since the triangle get smaller the scale factor has to be smaller than 1.

Answer:

I think it's 1456

Step-by-step explanation:

first, you have to calculate what in the parenthesis

(4*10)=40

(5.2*10-3) =(5.2*7)

5.2*7=36.4

so after you multiply 40*36.4

which equals 1456

Answer: Pay less sells the lowest price per marker.

Step-by-step explanation:

Step-by-step explanation:

Answer:

w = 5

3 x 5 = 15

3 x w will mean multiplication so you always want to do the opposite. First you want to get rid of known numbers such as the 3, to do that you will need to divide 3 from both sides! (As I had said use the opposite of the operations shown). 3 from 3 is obviously going to be 0 because your getting rid of the three, and 15 divided by 3 is 5! So therefore, you will be left with w = 5.

Answer:

w = 5

Step-by-step explanation:

15/3 = 5 or 3 x 5 = 15

Answer:

x = 5

Step-by-step explanation:

Given that BD bisects <ABC, it means that <ABC is divided into two equal angles, which are <ABD and <CBD.This implies that:

m<ABD = m<CBD. Therefore:

2(m<ABD) = m<ABC

Substitute:

2(2x + 12) = 44

Solve for x.

4x + 24 = 44 (distributive property)

4x + 24 - 24 = 44 - 24 (substraction property of equality)

4x = 20

4x/4 = 20/4 (division property of equality)

x = 5

Given:

A figure of a circle with secants intersecting inside the circle.

To find:

The value of x.

Solution:

According to the intersection theorem of secants, if two secants intersect each other inside the circle, then the angle on the intersection is the average of the intercepted arcs.

Using the intersection theorem of secants, we get

[tex]x^\circ=\dfrac{1}{2}(35^\circ+103^\circ)[/tex]

[tex]x^\circ=\dfrac{1}{2}(138^\circ)[/tex]

[tex]x^\circ=69^\circ[/tex]

[tex]x=69[/tex]

Therefore, the value of x is 69.

Answer:

Area = 20 in^2

Step-by-step explanation: 20/4=5  100/5=20

Answer:

20 inches squared

Step-by-step explanation:

20 ÷ 4 = 5

100÷5 = 20

The equation of line perpendicular to the line A is y = ( 1/6 )x + b

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

6x + y = 1

On simplifying , we get

Subtracting 6x on both sides , we get

y = -6x + 1

Now we can see that the slope of the given line is -6.

The slope of a line perpendicular to this line will be the negative reciprocal of -6, which is 1/6.

Therefore, an equation of a line that is perpendicular to the line 6x + y = 1 is of the form:

y = ( 1/6 )x + b

Hence , the equation of line is y = ( 1/6 )x + b
