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:

a = 8

b = 4[tex]\sqrt{2}[/tex]

Step-by-step explanation:

I've attached a picture of the 45-45-90 triangle's formula, which is the length of the hypotenuse = [tex]\sqrt{2}[/tex] times the length of a leg (one of the sides of the triangle).

So, applying this to your problem, if 4[tex]\sqrt{2}[/tex] if one of the legs of the triangle, the other leg, which is b , would be the same length.

b = 4[tex]\sqrt{2}[/tex]

To solve for a, you would have to multiply the leg by [tex]\sqrt{2}[/tex].

a = 4[tex]\sqrt{2}[/tex] x [tex]\sqrt{2}[/tex]

I would separate the 4 and the [tex]\sqrt{2}[/tex].

a = 4 x [tex]\sqrt{2}[/tex] x [tex]\sqrt{2}[/tex]

a = 4 x [tex]\sqrt{2 *2}[/tex]

a = 4 x [tex]\sqrt{4}[/tex]

a = 4 x 2

a= 8

The answer is A. unchanged

Answer:

1st question: 13 questions

2nd question: Mr.Philps will not have enough

Step-by-step explanation:

Mateo and Logan finished 65% of their math homework. If it has 20 problems, how many problems have they done?​

20 x 0.65 = 13

Mr. Philps made 1 gallon of fruit punch for his class party. If he has 27 students, and each of them will drink 1 cup, will he have enough?

1 gallon = 16 cups

27 students x 1 cup each = 27 cups

27 is greater than 16, so no, he will not have enough.

Answer:

Height of the tree is 20.25 m.

Step-by-step explanation:

Length of building AB = 54 m

Length of tree DE = 9 m

Shadow casted by the building (BC) = 24 m

Shadow casted by the tree (CE) = 9 m

Since, ΔABC ~ ΔDEC

By the property of similar triangles, corresponding sides of the similar triangles will be proportional.

[tex]\frac{AB}{DE}=\frac{BC}{EC}[/tex]

[tex]\frac{54}{h}=\frac{24}{9}[/tex]

h = [tex]\frac{54\times 9}{24}[/tex]

h = 20.25 m

Therefore, height of the tree is 20.25 m.

Answer:

Trapezoid

Step-by-step explanation:

They're showing us (with red arrows/triangles) that the bottom and top are parallel, but do not state anything like it for the sides.

That means it's at least a trapezoid.

As nothing suggests the sides are parallel, it's likely not a parallelogram (and it doesn't look like one).

It's also not a kite, as there is no indication that pairs of neighboring sides are equal in length.

As we don't think it's a parallelogram, it's thus not a rectangle (every rectangle is a parallelogram).

Similar with rhombus (every rhombus is a parallelogram) and square (every square is a parallelogram AND a rhombus).

Answer: 14a - b - 3c + 21

Answer:

31

Step-by-step explanation:

Answer:

-3 - (-9)

As we have '-' sign outside bracket, the sign inside the brackert will become opposite, thus we will have,

⇒ -3+9

⇒ 6

-3 - (-9) change the signs -3+9 then calculate which gives your answer 6

Answer:

4 goats

Step-by-step explanation:

Let us represent

Number of quails = x

Number of goats = y

Quails have 2 legs

Goats have 4 legs

Hence:

There are 6 animals in the pen some are quails and some are goats

x + y = 6...... Equation 1

x = 6 - y

if there are 20 legs in all how many quails

2x + 4y = 20..... Equation 2

We substitute 6 - y for x in Equation 2

2(6 - y) + 4y = 20

12 - 2y + 4y = 20

Collect like terms

- 2y + 4y = 20 - 12

2y = 8

y = 8/2

y = 4 goats

The number of goats there are 4 goats
