Answer:

4 baby blue paints

Step-by-step explanation:

Given

Let b represents blue paint and w, white paints

[tex]b : w = 5 : 2[/tex] ---for 1 paint

Required

The number of paints in [tex]20 : 8[/tex]

To do this, we set the following equivalent ratios

[tex]5n:2n = 20 : 8[/tex]

Where n represents the number of paints

By comparison

[tex]5n = 20[/tex]

[tex]2n = 8[/tex]

Solve for n in both cases;

[tex]5n = 20[/tex]

[tex]n = \frac{20}{5}[/tex]

[tex]n = 4[/tex]

[tex]2n = 8[/tex]

[tex]n = \frac{8}{2}[/tex]

[tex]n = 4[/tex]

Answer:

  (x, y) = (-2, 7)

Step-by-step explanation:

Add the first equation to twice the second.

  (4x +4y) +2(2x -2y) = (20) +2(-18)

  8x = -16 . . . . . . simplify

  x = -2 . . . . . . . . divide by 8

__

  2(-2) -2y = -18 . . . . .substitute into the second equation

  y + 2 = 9 . . . . . . . . . divide by -2

  y = 7 . . . . . . . . . . . subtract 2

The solution is (x, y) = (-2, 7).

Answer:

Step-by-step explanation:

The marked external angle at B is "corresponding" to the internal angle BAD, so is the same measure. This means ...

  z° +40° = 121°

  z° = 81°

__

Adjacent angles of a parallelogram are supplementary, so ...

  ∠CDA +∠BAD = 180°

  x° + 121° = 180°

  x° = 180° -121°

  x° = 59°

__

Alternate interior angles are congruent, so ...

  y° = 40°

Answer:

12 because 108/12 is 9

Step-by-step explanation:

3^2=9

The common ratio of the geometric sequence whose first term 3 and third term 108 is ±6.

A geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

Here, first term a = 3 ......(i)

third term a₃ = ar² = 108 .......(ii)

On dividing equation (ii) from equation (i), we get

[tex]\frac{ar^{2} }{a} = \frac{108}{3}[/tex]

r² = 36

r = ±6

Thus, the common ratio of the geometric sequence whose first term 3 and third term 108 is ±6.

Answer:

A. 45h = 1,575

Step-by-step explanation:

Area of trapezoid = 1,575 cm² (given)

We are given the length of both bases, a = 63 cm and b = 27 cm

We need to find the formula that will enable us determine its height (h).

Thus:

Area of trapezoid = ½(a + b)h

Plug in the values

½(63 + 27)h = 1,575

½(90)h = 1,575

45h = 1,575

The answer is A. 45h = 1,575

Just think: which number would have the greatest value if it was rounded to the nearest hundredth

Answer: A

Step-by-step explanation:

I think the answer is correct becuase, If we taken all the numbers and put them on a number line they would all be under one. But when we look at the number line we would see that .987 is the closest because it is almost a whole number. And even if we did it without the number line what ever number we see that has the greatest digit and its in the negatives thats the closest to one. (I hope what I said makes sense!)

Answer:

short leg: 4

hypotenuse: 8

this is a 30,60,90 triangle.

angle against the 90 degrees is the hypotenuse. Against the 60 degrees is the long leg and against the 30 degrees is the short leg. So since we know the long leg we can find the short leg. The short leg is the long leg/ square root(3) so the short leg is 4.

Now to find the hypotenuse youdo 4^2 + 4 square root(3)^2 which is 64 squared. Or 8

Answer:

27.91 pretzels.

Step-by-step explanation:

Knowing that 1/3 of 33 bakers can make 89 pretzels in 2 1/2 hours, to determine how many pretzels can 5 3/4 bakers make in 1 1/2 hours the following calculation must be performed:

33 x 1/3 = 11

89 / 2.5 / 11 = X

35.6 / 11 = X

3.236 = X

3/4 = 0.75

3.236 x 1.5 x 5.75 = X

4.854 x 5.75 = X

27.91 = X

Therefore, 5 3/4 bakers can make 27.91 pretzels in 1 1/2 hours.

Answer:

11x+2y

Step-by-step explanation:

Answer:

a) 0.152 = 15.2% probability that this person is a female who engages in physical exercise activities during the lunch hour.

b) 0.248 = 24.8% probability that this person is a female who does not engage in physical exercise activities during the lunch hour.

Step-by-step explanation:

Question a:

20% of employees engage in physical exercise.

This 20% is composed by:

8% of 60%(males)

x% of 100 - 60 = 40%(females).

Then, x is given by:

[tex]0.08*0.6 + 0.4x = 0.2[/tex]

[tex]0.4x = 0.2 - 0.08*0.6[/tex]

[tex]x = \frac{0.2 - 0.08*0.6}{0.4}[/tex]

[tex]x = 0.38[/tex]

0.38 = 38%

Probability of being a female who engages in exercise:

40% are female, 38% of 40% engage in exercise. So

0.38*0.4 = 0.152

0.152 = 15.2% probability that this person is a female who engages in physical exercise activities during the lunch hour.

B. If we choose an employee at random from this corporation,what is the probability that this person is a female who does not engage in physical exercise activities during the lunch hour?

40% are female, 100% - 38% = 62% of 40% do not engage in exercise. So

0.62*0.4 = 0.248

0.248 = 24.8% probability that this person is a female who does not engage in physical exercise activities during the lunch hour.

Answer: I think it is 36 shovelfuls

Step-by-step explanation:

V = πr²h

V = π • 6² • 12

V = π • 36 • 12

V = 1357.2in³

V = 1/3πr²h

V = 1/3 • π • 3² • 4

V = 1/3 • π • 9 • 4

V = 1/3 • π • 36

V = 37.7in³

1357.2 ÷ 37.7 = 36 shovelfuls

Answer and Step-by-step explanation:

The answer is 54.

We see that each time, the number is being multiplied by 1.5.

54 times 1.5 = 81 * 1.5 = 108

54 times 2 = 108

54 is the starting number, because when you multiply 54 by 1, you get 54 for y.

#teamtrees #PAW (Plant And Water)

Answer: y = 54x

The easiest way to do this is by looking at the column where x = 1. In that column, y = 54, so we know that x times 54 would be equal to y.

If you don't have a column where x = 1, you can divide the y value by the x. Here are two examples:

27 ÷ 0.5 = 54

81 ÷ 1.5 = 54

Answer: 285.2 kg

Given

The volume of helium in the balloon is [tex]V=1592\ m^3[/tex]

The density of the helium is [tex]\rho =0.1785\ kg/m^3[/tex]

Mass of the helium gas is given by the product of density and volume

[tex]\Rightarrow M=\rho \cdot V\\\Rightarrow M=0.1785\times 1592\\\Rightarrow M=285.2\ kg[/tex]

Thus, the mass of gas is 285.2 kg
