Answer: 480 mL, 600 mL

Step-by-step explanation:

Given

The concentration of the first acid is 75%

The concentration of the second acid is 30%

The final mixture has a concentration of 50%

The final volume is 1080 mL

Suppose x and y be the volume of the first and second acid

[tex]\therefore x+y=1080\quad \ldots(i)\\0.75x+0.3y=0.5\times 1080\quad \ldots(ii)[/tex]

Solving the above equations we get

[tex]x=480,y=600[/tex]

So, the quantity of the first acid is 480 mL and 600 mL for the second mixture.  

answer: 1/2

Step-by-step explanation:

Assuming this is a 6 sided number dice The answer would be 3/6 but in simplest form 1/2 because 2, 3, and 5 is half of the numbers on a dice example: 2, 3, 5, 1, 4, and 6 are all the possibilities Hope this helps!

Answer:

10 because you need to find how much one pen would cost. So you decide 5 and 4. the result would be 1.25 then you multiple the result by 8. you get 10

Answer:

Cos A < 0 in the 3rd and 4th quadrants

Tan A < 0 in the 2nd and 4th quadrants

Step-by-step explanation:

In trigonometry, we make use of the ACTS initials to get which quadrant has it's sine, cosine or tangent functions as negative or positive.

In quadrant 1, it is denoted by A meaning All of sine, cosine and tangent functions are positive

In quadrant 2, it is denoted by C to mean that only cosine is positive i.e. greater than 0.

In quadrant 3,it is denoted by T to mean that only cosine is positive i.e. greater than 0.

In quadrant 4, it is denoted by S to mean that only sine is positive i.e. greater than 0.

Thus, comparing all above with the question, we can say that;

Cos A < 0 in the 3rd and 4th quadrants

Tan A < 0 in the 2nd and 4th quadrants

Answer:

Step-by-step explanation:

Start like this: x^2 - 6x = -7. Now you have the x terms on one side and the constant on the other. Take half the linear term (-6x) which is 3 and then square that (9) and add it to both sides, giving you x^2 - 6x + 9 = -7+ 9, or x^2 - 6x + 9 = 2. Now make the left side into the perfect square binomial you created by completing the square: (x-3)^2 = 2, and then move the 2 over to get: (x-3)^2 - 2. That's the vertex form for a parabola with a vertex at (3, -2)

Answer:

360 degrees = 68 + 31 + 115 + GJ

GJ = 360 -68 -31 -115

GJ = 146

Inscribed Angle = 1/2 of intercepted arc

Angle GHJ = 146 / 2 = 73 degrees

Angle GIJ = 146 / 2 = 73 degrees

3/5 == 0.6

Which part of the line is 0.6?

A < 0.5 so there's no way A can be the answer.

C > .75 so it can't be the answer either.

D > 1.5 so it can't be the answer either.

B is the only answer left and it sits just right in front of 0.5, which is close to 0.6.

Answer: [tex]130.9^{\circ}[/tex]

Step-by-step explanation:

Given

The number of students in the first year is 800

The number of students in the second year is 950

The number of students in the third year is 1000

If this data is graphed on a pie chart, then the area percentage of area occupied by third years is

[tex]\Rightarrow \dfrac{1000}{1000+950+800}\times 100=36.36\%[/tex]

Now, the angle around the center of the circle is [tex]360^{\circ}[/tex]

[tex]\therefore \text{angle covered by third years=}0.3636\times 360^{\circ}\\\Rightarrow 130.896\approx 130.9^{\circ}[/tex]

Answer:

79 would be rounded to the nearest hundredth

Answer:

78.57

Step-by-step explanation:

The number in the hundredths place is 7. 78.570

So then you look to the number to the right which is zero so you round down to 78.57

So, the answer is the same.

78.57

Answer:

9 green balloons

Step-by-step explanation:

17-8=9

Answer:

Brad has 9 green balloons.

Step-by-step explanation:

......

Answer:

Our range is within [0,2π]

We cant exceed that.

tan∆ + 1=0

tan∆= -1

∆=tan-¹(-1)

∆=-45°

Now it has 3 Solutions within the given interval

-45° x π/180 = -π/4

So For the second quadrant... 180-∆ = 180-45 =135°

It is true for tan(135) Which is also equal to -1

135xπ/180 = 3π/4

then

360-45 = 315

This is also true because tan(315)=-1

315° x π/180 = 7π/4

This is where we stop so we dont exceed the given range.

The probability that the sum is greater than 12 is  [tex]\frac{2}{3}[/tex].  The probability the product is 72 is [tex]\frac{1}{6}[/tex].

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Probability(Event) = Favorable Outcomes/Total Outcomes

The outcomes that the sum is greater than 12

6 and 12, 6 and 15, 12 and 15, 0 and 15

So the probability that the sum is greater than 12 is

= [tex]\frac{4}{C^{2} _{4} }[/tex]

= [tex]\frac{4}{6}[/tex]

= [tex]\frac{2}{3}[/tex]

The outcomes that the product is 72: 6 and 12

So the probability is

= [tex]\frac{1}{C^{2} _{4} }[/tex]

= [tex]\frac{1}{6}[/tex]

Hence, the probability that the sum is greater than 12 is  [tex]\frac{2}{3}[/tex].  The probability the product is 72 is [tex]\frac{1}{6}[/tex].

Step-by-step explanation:

At x=0, this function's y-value is simply 10. At x=2, the y-value is 28.

We can figure this out by using the slope formula.

Answer:

A. 6x + 4

B. 22 cm

Step-by-step explanation:

The perimeter of the triangle is equal to the sum of all the side lengths, which is (2x+3) + (x+1) + (3x), or 6x + 4.

When x = 3cm, the perimeter is 6(3) + 4, which is 22 cm.

Answer:

answer is 4 im pretty sure

Step-by-step explanation:

did da math

If the measure of an angle is 360°, then the value of sin²θ + cos²θ = 1 will be  0² + 1² = 1. Then the correct option is B.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|² = |AB|² + |BC|²    

where |AB| = length of line segment AB. (AB and BC are the rest of the two sides of that triangle ABC, AC being the hypotenuse).

The equation is given below.

sin²θ + cos²θ = 1

If the angle is 360°. Then the equation will be

sin²360° + cos²360° = 1

                      0² + 1² = 1

Then the correct equation is B.
