Answer:

  B.  28%

Step-by-step explanation:

You want to know the percent of the mixture that is fruit juice, if the mixture is 6 L of 52% juice and 9 L of 12% juice.

The total amount of juice in the 6+9 = 15 L of mix is ...

  0.52·(6 L) +0.12(9 L) = 3.12 L +1.08 L = 4.2 L

Then the fraction of the mix that is fruit juice is ...

  (4.2 L)/(15 L) = 0.28 = 28%

The percent of the mixture that is fruit juice is 28%, choice B.

Step-by-step explanation:

The value of DF would be,

DF = 1.38

We are given that triangle ABC is similar to triangle DEF.

Therefore, we can set up the following proportion:

AB/DE = BC/EF = AC/DF

We are given the lengths of AB, AC, and BC, so we can substitute those values into the proportion:

11/2 = 7.9/EF = 7.6/DF

We are asked to find the length of DF, so we can isolate DF by cross-multiplying:

11/2 = 7.6/DF

DF = 7.6 x 2 / 11

DF = 1.38

Thus, The value of DF would be,

Emma has $5,000 total invested.

Let's call the total amount Emma has invested "x".

Emma has half of her investments in stock paying a 10% dividend, so that portion of her investment earns 0.10(x/2) = 0.05x in annual interest.

The other half of her investments are in a stock paying 14% interest, so that portion of her investment earns 0.14(x/2) = 0.07x in annual interest.

The total annual interest Emma earns is $600, so we can set up the following equation:

0.05x + 0.07x = 600

0.12x = 600

x = 5000

Therefore, Emma has a total of $5000 invested.

Answer:

0.90

Step-by-step explanation:

Just like a decimal to a percentage number, you must multiply by 100. By converting a percentage number to a decimal point, you must divide it by 100. Which means, the decimal must move 2 times.

For example,

0.90 x 100 = 90%

This is decimal to percentage number, but in this case it is percentage to decimal.

90%.

Since the number ended at 0, put the decimal there and move it 2 times to get to your decimal point.

.90 = 0.90

There you'll get your answer! ^^

90% = 0.90

The quadratic equation that has 5i and -5i as solutions is:

x²+ 25 = 0

The quadratic equation is the polynomial having the highest power of 2. If 5i and -5i are the solutions to the quadratic equation, then the quadratic equation can be written as:

(x - 5i)(x + 5i) = 0

Expanding this equation, we get:

x² - (5i)² = 0

x² - 25i² = 0

Since i² = -1, we can substitute -1 for i², giving us:

x² - 25(-1) = 0

x² + 25 = 0

Therefore, the quadratic equation that has 5i and -5i as solutions is:

The expression 6(a-3) can be simplified by applying the distributive property of multiplication over addition, which gives 6a - 18. Therefore, the expression is equivalent to 6a - 18. The answer is (b) –2. All other options do not simplify to the same expression as 6(a-3). For example, 18a is not equivalent to 6(a-3) and neither is 6(a)-6(3).

The percentage of saline solution in brand B is 3%. Then the correct option is C.

Since Danielle combined brands A and B to create a total of 18 gallons of 8% saline solution, we know that the total volume of saline solution in the combination is 18% of 6 gallons + x% of (18 - 6) gallons.

Thus, we can set up the equation:

0.18(6) + 0.01x(18 - 6) = 0.08(18)

Simplifying and solving for x, we get:

Answer:

Faster cyclist = 37.5km/h

Slower cyclist = 32.5km/h

Step-by-step explanation:

Let's call the rate of the slower cyclist "r" (in km/h). Then the rate of the faster cyclist is "r+5" (in km/h), since they are traveling 5 km/h faster.

We know that the two cyclists are traveling towards each other and will meet in 2 hours. We can use the formula:

distance = rate × time

Let's call the distance each cyclist travels "d". Since they are traveling towards each other, their distances will add up to the total distance between the two towns, which is 130 km. So we can write:

d + d = 130

2d = 130

d = 65

Now we can use the formula again to find the rates of the two cyclists:

For the slower cyclist:

distance = rate × time

65 = r × 2

r = 32.5 km/h

For the faster cyclist:

distance = rate × time

65 = (r+5) × 2

r+5 = 32.5 + 5 = 37.5 km/h

So the rate of the slower cyclist is 32.5 km/h, and the rate of the faster cyclist is 37.5 km/h.

The area of the shaded region is equal to 12.5π or 39.27 square centimeters.

In Mathematics and Geometry, the area of a semicircle can be calculated by using this formula:

Area of semicircle, As = πr²/2

Where:

r represents the radius of a circle.

Note: Radius = diameter/2 = 20/2 = 10 centimeters.

By substituting the radius into the formula for the area of a semicircle, we have the following;

Area of semicircle = 1/2 × π × 10²

Area of semicircle = 50π square centimeters.

For the circle, we have:

Area of circle, Ac = πr²

Area of circle, Ac = π(10/2)²

Area of circle, Ac = 25π square centimeters.

Now, we can determine the area of the shaded region as follows;

Area of shaded region = (As - Ac)/2

Area of shaded region = (50π - 25π)/2

Area of shaded region = 12.5π or 39.27 square centimeters.

Answer: $6,320.25

Step-by-step explanation:

Mrs. Cowley's broker fee is calculated by multiplying the purchase price by the broker fee percentage: $32,000 x 0.0075 = $240. Her total cost for the purchase is then $32,000 + $240 = $32,240. When she sells the stock for $25,100, she incurs another fee of $17 for using the discount broker. To calculate her net loss, we subtract her total cost from her selling price and subtract the two broker fees: $25,100 - $32,240 - $17 - $17 = -$6,320.25, which is rounded to $6,320.25 as a net loss.

Comparing the equations of the two lines, we can see that they have the same slope (3/2). Therefore, the lines are parallel.

To determine whether these two lines are parallel or perpendicular, we can convert Line 2 into slope-intercept form (y = mx + b):

2y = 3x + 5

y = (3/2)x + 5/2

Comparing this equation to the equation of Line 1 (y = x + 7), we see that the slopes (coefficients of x) of the two lines are not equal, nor are they negative reciprocals of each other. Therefore, the lines are neither parallel nor perpendicular.

Line 1 and Line 3:

To determine whether these two lines are parallel or perpendicular, we can convert Line 3 into slope-intercept form (y = mx + b):

6x - 4y = 4

-4y = -6x + 4

y = (3/2)x - 1

Comparing this equation to the equation of Line 1 (y = x + 7), we see that the slopes of the two lines are not equal, nor are they negative reciprocals of each other. Therefore, the lines are neither parallel nor perpendicular.

Line 2 and Line 3:

To determine whether these two lines are parallel or perpendicular, we can convert Line 2 into slope-intercept form (y = mx + b):

2y = 3x + 5

y = (3/2)x + 5/2

Next, we can rearrange Line 3 into the slope-intercept form:

6x - 4y = 4

-4y = -6x + 4

y = (3/2)x - 1

Comparing the equations of the two lines, we can see that they have the same slope (3/2). Therefore, the lines are parallel.

As per the Pythagorean theorem, the length of the missing side, c, is approximately 8.06 units.

Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Now, let's use the Pythagorean Theorem to find the length of the missing side in your problem. You have a right-angled triangle with side a = 4 and side b = 7. To find the length of the missing side, let's call it c, we need to use the Pythagorean Theorem, which is:

c² = a² + b²

In this case, we know the values of a and b, so we can substitute them into the equation:

c² = 4² + 7²

Simplifying the right-hand side, we get:

c² = 16 + 49

c² = 65

The value c = -2.07 for a standard normal distribution with P(z < c) = 0.0234.

To find the value of c for which P(z < c) = 0.0234 for a standard normal distribution, we can use a standard normal distribution table or a calculator with a built-in normal distribution function.

Using a standard normal distribution table, we can look up the area to the left of c and find the corresponding z-score. This z-score will be the value of c for which P(z < c) = 0.0234.

Looking up the area 0.0234 in the table, we find that the corresponding z-score is approximately -2.07.

Answer: B

Step-by-step explanation:

First, you have to know that a straight line is equal to 180 degrees. They gave you 115 degrees in part of a line, so the other part or the angle not given must be equal to 65 degrees. Another thing is that a triangle has 180 degrees. 65+80 degrees is equal to 145 degrees, leaving angle 1 to be equal to 35 degrees. Another thing to know is that reflective angles have the same measurement. If the original angle was equal to 65 after subtraction 115 from 180, we know that the second triangle's angle would also be equal to 65. 65+86 is 150, and 180-150 is 30. Thus, the answer is B.
