Answer:

42% acid

Step-by-step explanation:

Suppose that these two storage containers are filled to complete capacity?

That makes the second container have 3 volume parts and the first container having 2 volume parts.

v*(1.50)= (3/2)*v

First Container     2v       30% acid

Second Container    3v       50% acid

The mixture of all of this is in the third container. Two parts plus three parts is 5 parts for the mix volume.

=(2*30+3*50)/5

=210/5

=42

So,

42 % Acid, mixture

Final answer:

After calculating the quantities of acid from both containers and their total volume, the final acid concentration in the mixture in the third container is found to be 42%.

Explanation:

The student has asked about finding the percentage of acid in a third container after mixing two solutions with different acid concentrations. This question involves proportion and percentage calculations, which are commonly covered in high school mathematics.

To find the final concentration of acid in the third container, we can use the formula final concentration = (quantity of acid in container 1 + quantity of acid in container 2) / total volume. Assume the first container has a volume of V liters. Since the second container is 50% larger, it has a volume of 1.5V liters.

Acid in the first container = V liters × 30% = 0.3V liters

Acid in the second container = 1.5V liters × 50% = 0.75V liters

Total volume = V + 1.5V = 2.5V liters

Thus, the final concentration of acid = (0.3V + 0.75V) / 2.5V = 1.05V / 2.5V = 42%.

The final acid concentration in the third container is 42%.

The percent error in the kitchen scale's measurement is found using the formula ((Measured Value - Actual Value) / Actual Value) × 100%, resulting in a 25% error when comparing the scale's reading of 2 pounds to the actual weight of 1.6 pounds.

The question asks to find the percent error for a kitchen scale when measuring the weight of a piece of fruit. The percent error is a way of comparing the accuracy of a measurement to the actual value, and it's calculated using the formula: Percent Error = ((|Measured Value - Actual Value|) / Actual Value) × 100%. In this case, the measured value is 2 pounds and the actual value is 1.6 pounds.

First, subtract the actual value from the measured value: 2 - 1.6 = 0.4 pounds. Then, divide this difference by the actual value: 0.4 / 1.6 = 0.25. Finally, multiply by 100% to find the percent error: 0.25 × 100% = 25%.

Therefore, the percent error for the kitchen scale is 25%. This calculation helps in understanding the accuracy and reliability of measurements taken by the scale.

Answer:

y-9= -4(x+1)

Step-by-step explanation:

First, you should know what the format for point slope form is. y-y1=m(x-x1). Now, fill in the points to the x1 and y1 variables. It doesn't matter what ordered pair you use. If the number you fill in is negative, for example, -1, change it to a positive 1. If you're plugging in a positive number such as 9, it becomes -9. Now, it may look like this: y-9=m(x+1). However, you still need to find slope. You can use the expression y-y1/x-x1. 9-1=8. -1-1= -2. So, your slope is 8/-2. However, you can simplify this to -4. Now, plug in -4 to your equation to have your final answer: y-9=-4(x+1).

Answer:

351.9 cubic in

Step-by-step explanation:

The volume of a cylinder is hr²π.

r is half the diameter, so 8/2 is 4.

Plug in your h and r and get:

7 * 4² * π

7 * 16 * π

112π

Multiply the π and you'll get about 351.9 cubic in

The volume of the cylinder is 352 cu.inches.

A cylinder is a three-dimensional figure, it is made up of parallel circular discs of the same radius.

The cylinder consists of two circular bases, connected by a curved surface at a fixed distance.

A cylinder has a base diameter of 8 inches and a height of 7 inches.

The volume is the space occupied by a three-dimensional object.

The volume of the cylinder is given by the formula

V = πr²h

Here, r is the radius of the base,

h is the height of the cylinder.

The volume is determined in cubic units.

The value of r = diameter / 2

r = 8/2 = 4 inches

h = 7 inches.

Substituting these values in the formula to determine the volume,

Volume = (22/7) * 4² * 7

Volume = (22/7) * 16 * 7

Volume = 22 * 16

Volume = 352 cu.inches

Answer:

[tex]\angle ACD = 130 ^\circ[/tex].

Step-by-step explanation:

[tex]\angle ABC[/tex] and [tex]\angle EBC[/tex] are supplementary angles. Their sum should be [tex]180^\circ[/tex].  [tex]\angle EBC = 120^\circ[/tex] [tex]\implies \angle ABC = 180^\circ - \angle EBC = 180^\circ - 120^\circ = 60^\circ[/tex].

The sum of the three angles in triangle [tex]\triangle ABC[/tex]: [tex](\angle ABC + \angle BAC + \angle ACB)[/tex] should be equal to [tex]180^\circ[/tex].

[tex]\angle ABC = 60^\circ[/tex] and [tex]\angle BAC = 70^\circ[/tex] [tex]\implies \angle ACB = 180^\circ - \angle ABC - \angle ACB = 180^\circ - 70^\circ - 60^\circ = 50^\circ[/tex].

[tex]\angle ACB[/tex] and [tex]\angle ACD[/tex] form another pair of supplementary angles. Their sum should also be [tex]180^\circ[/tex]. [tex]\angle ACB = 50^\circ[/tex] [tex]\implies \angle ACD = 180^\circ - \angle ACB = 180^\circ - 50^\circ = 130^\circ[/tex].

Answer:

The ball lands  18 feet from where it is kicked.

Step-by-step explanation:

Given : The path of a ball kicked from the ground can be modeled by the equation [tex]y=-\frac{1}{3}(x-3)(x-21)[/tex], where x and y are measured in feet. The x-axis represents the ground.

To find : How far does the ball land from where it is kicked?

Solution :

According to question,

The value of y is zero as it is kicked from ground.

So, [tex]0=-\frac{1}{3}(x-3)(x-21)[/tex]

Applying zero product property,

[tex]a\cdot b\cdot c=0\Rightarrow a=0\text{ or }b=0\text{ or }c=0[/tex]

i.e. [tex]-\frac{1}{3}\cdot (x-3)\cdot (x-21)=0[/tex]

[tex]x-3=0[/tex]

[tex]\Rightarrow x=3[/tex]

[tex]\text{ or }x-21=0[/tex]

[tex]\Rightarrow x=21[/tex]

The distance the ball land from where it is kicked is d=21-3=18.

Therefore, the ball lands  18 feet from where it is kicked.

The ball lands 18 feet from where it is kicked.

To find out how far the ball lands from where it is kicked, we need to determine the horizontal distance traveled by the ball when it hits the ground again. The x-axis represents the ground, so we are looking for the x-coordinate of the point where the ball lands, which is when y = 0.

Given the equation of the path of the ball:

[tex]\[ y = -\frac{1}{3}(x - 3)(x - 21) \][/tex]

We set y to 0 to find the x-coordinates where the ball touches the ground:

[tex]\[ 0 = -\frac{1}{3}(x - 3)(x - 21) \][/tex]

This equation can be factored to:

[tex]\[ 0 = (x - 3)(x - 21) \][/tex]

Setting each factor equal to zero gives us two solutions for x:

[tex]\[ x - 3 = 0 \quad \text{or} \quad x - 21 = 0 \][/tex]

[tex]\[ x = 3 \quad \text{or} \quad x = 21 \][/tex]

These solutions represent the x-coordinates where the ball is kicked (x = 3) and where it lands (x = 21). To find the distance between these two points, we subtract the smaller x-coordinate from the larger one:

 [tex]\[ \text{Distance} = 21 - 3 = 18 \text{ feet} \][/tex]

However, since the ball is kicked from the ground and lands back on the ground, the distance it travels horizontally is the absolute value of the difference between the two x-coordinates:

[tex]\[ \text{Horizontal distance} = |21 - 3| = |18| = 18 \text{ feet} \][/tex]

Answer:

Yes, it could be a triangle.

Step-by-step explanation:

If the Pythagorean Theorem is satisfied, then these three side lengths represent a right triangle:

However, the sum 21 + 28 is greater than 36, so we could indeed construct a triangle from these 3 side lengths.  It just wouldn't be a right triangle.

Answer:

4 is a factor of 20.

Step-by-step explanation:

Final answer:

The true statement regarding factors is that 4 is a factor of 20. This is proven by dividing 20 by 4, which results in 5 without any remainder.

Explanation:

The question asks which statement is true regarding factors of numbers. A factor is a number that can divide another number without leaving a remainder. For example, 4 is a factor of 20 because when you divide 20 by 4, there is no remainder, and you get 5 which is a whole number. So the true statement among the given options is that 4 is a factor of 20.

Looking at the other options, 4 is not a factor of 18 since 18 divided by 4 gives you 4 with a remainder of 2. Similarly, 4 is not a factor of 26 because 26 divided by 4 is 6 with a remainder of 2. Lastly, 4 is not a factor of 30 because 30 divided by 4 is 7 with a remainder of 2. Therefore, the correct answer is that 4 is a factor of 20.
