Answer:

No, Jasmine is not correct. The Lowest Common Multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. Multiplying the two numbers together is not always the correct method to find the LCM.

For example, the LCM of 5 and 8 is 40, but the product of 5 × 8 = 40 is not the LCM.

A more accurate way of finding the LCM is by using the prime factorization of the numbers. By finding the prime factorization of the two numbers, you can take the highest exponent of each prime factor and multiply them together. The result of that multiplication is the LCM of the two numbers.

In this case, the prime factorization of 5 is 5 and 8 is 2^3. The LCM of 5 and 8 is 2^3*5 = 40. So Jasmine's claim that 5 x 8 = 40 and the LCM of 5 and 8 is 40 is not correct.

Step-by-step explanation:

Let the other diagonal be d.

From the Pythagorean theorem,

d2 = 82 + 1442

d2 = 64 + 20736

d2 = 20800

d = √20800

d = 144 cm

The expression 4√72 can be simplified by first taking the square root of both sides, which gives us 2√72. Then, we can factor out a 6 from both sides, which gives us 24√6. Therefore, the simplified expression is 24√6.

The Angle Bisector Theorem states that in a triangle, if a line bisects one angle of a triangle and is also a median to the side opposite of that angle, then the ratio of the length of the median to the length of the side opposite the angle bisected is equal to the ratio of the length of the other two medians.

Therefore, if the angle bisector divides the opposite side into segments 6 cm and 9 cm long, the ratio of the length of the median to the length of the side opposite the angle bisected is 6/9.

Let x be the length of the third side of the triangle.

The Angle Bisector Theorem states: (x/22.5) = (6/9)

Solving for x, we get: x = (22.5 * 6/9) = 15

So the length of the third side of the triangle is 15 cm.

This is the only possible length for the third side of the triangle because the Angle Bisector Theorem only holds if the angle bisector is also a median to the side opposite of that angle.

Serena added 10 grams of sugar to 20 grams of water to make a sugar syrup.

The total amount of sugar syrup made is the sum of the weight of sugar and the weight of water, so:

10 grams (sugar) + 20 grams (water) = 30 grams (sugar syrup)

To find the percentage of sugar in the syrup, we can divide the weight of the sugar by the total weight of the syrup and multiply by 100.

% sugar = (weight of sugar / total weight of syrup) * 100

% sugar = (10 / 30) * 100 = 33.333 %

So the sugar syrup made by Serena contains 33.333% sugar by weight.

It's important to note that the sugar syrup doesn't have only sugar, it also have water, the sugar is just the main ingredient and the percentage of sugar is just the proportion of sugar within the syrup.

Step-by-step explanation:

You want a couple of interior angles and the value of x given the parallelogram in the figure.

The diagonals of a parallelogram bisect each other, and divide the figure into two pairs of congruent triangles. Here, the congruent triangles of interest are ...

  ∆NKJ≅∆NML

In these triangles, that means ...

  ∠J ≅ ∠L = 50° = ∠NJK

  ∠K ≅ ∠M = 42° = ∠NKJ

The halves of diagonal JL are congruent, so we have ...

  4x -3 = 13

  4x = 16 . . . . . . . . add 3

  x = 4 . . . . . . . . . divide by 4

The output voltage, in millivolts (mV), for the circuit would be equal to 1,350 millivolts.

An amplifier is defined as the electronic device that can be used to increase the electrical signal of a power source.

The output voltage of an amplifier= input voltage × gains.

We have been given that input voltage = 45 mV

The gain = 30

Answer: D - 124°

Step-by-step explanation: Since y and a are vertical angles, we can determine that angle a is equal to 34°

90° + 34° = 124°

180° - 124° = 56°

Now we know the last angle in the triangle. Since this angle is on the same line as angle b, subtracting it from 180 would give us angle b

180° - 56° = 124°

Answer:

If an engineer typically makes 50% more than a school teacher, then the engineer's income is 150% of the school teacher's income. Because 100% represents the school teacher's income, and 50% represents the engineer's additional income, the sum is 100%+50% = 150%.

The engineer's income is also 1.5 times as large as the school teacher's income. This can be found by dividing the engineer's income percentage (150%) by the school teacher's income percentage (100%), which gives 150% / 100% = 1.5.

So the engineer's income is 150% of the school teacher's income, and it is 1.5 times as large as the school teacher's income.

Answer: The distance formula is a mathematical formula used to find the distance between two points in a plane. One way to find the distance formula is by using the Pythagorean theorem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The distance formula can be derived from the Pythagorean theorem by considering the two points as the two endpoints of a line segment. The formula is as follows:

Distance = √(x2 - x1)^2 + (y2 - y1)^2

where (x1, y1) and (x2, y2) are the coordinates of the two points.

In this formula, the difference in the x-coordinates is squared and the difference in the y-coordinates is also squared. Then, these two values are added and the square root of the result gives the distance between the two points.

For example, if we have two points (x1, y1) = (2, 3) and (x2, y2) = (5, 8), we can use the distance formula to find the distance between these two points:

Distance = √((5 - 2)^2 + (8 - 3)^2)

Distance = √(3^2 + 5^2)

Distance = √(9 + 25)

Distance = √(34)

Distance = 5.83

Therefore, the distance between the two points is 5.83 units.

Step-by-step explanation:

The value of AE is, 10 units.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Here, From the given figure we can see that two triangle ABE and DEC are similar.

Therefore, The ratio of corresponding sides are equal.

Hence, From figure we get,

⇒ ED/AE = CD/AB

Substitute all the values, we get;

⇒ (x + 6)/(2x + 6) = 8/10

⇒ 10(x + 6) = 8(2x + 6)

⇒ 10x + 60 = 16x + 48

⇒ 16x - 10x = 60 - 48

⇒ 6x = 12

⇒ x = 2

So, The value of AE is,

AE = 2x + 6

AE = = (2 × 2 ) + 6

AE = 4 + 6

AE = 10

Answer:

The equation of this line is y>1/2x-3

Step-by-step explanation:

This is an inequality equation that represents a line that is greater than 1/2x-3. The inequality symbol ">" indicates that all the y-coordinates that are on the same side of the line as the y-axis are greater than 1/2x-3.

In other words, all the points that lie above the line will satisfy the inequality, while all the points that lie below the line will not.

It's worth noting that the line y<1/2x-3 represents the same line but the inequality symbol "<" indicates that all the y-coordinates that are on the same side of the line as the x-axis are less than 1/2x-3.

y>2x-3 and y<2x-3 represent different lines, the first one represents a line with a slope of 2 and the second one represents a line with a slope of -2.

If I manage an ice cream factory that makes two flavors: Creamy Vanilla and Continental Mocha. Into each quart of Creamy Vanilla go 2 eggs and 3 cups of cream. Into each quart of Continental Mocha go 1 egg and 3 cups of cream. Where I have in stock 500 eggs and 1,050 cups of cream. The number of quarts of each flavor that I would make in order to use up all the eggs and cream is: 150 quarts of Vanilla and 200 Quarts of Mocha.

Let x and y be the number of Quarts of Vanilla and Mocha respectively.

The total number of eggs used is given as:

2x+y = 500

And the total cups of cream is:

3x + 3y = 1050

Removing the second equation from three times the first, we get:

3(2x + y) - (3x + 3y) = 3(500) -1050

6x + 3y - 3x - 3y = 1500 - 1050

⇒ 3x = 450

⇒ x = 450/3

x = 150

By substituting x back in tot he first equation we find:

2x+y = 500

2 (150) + y = 500

300 + y = 500

y = 500 - 300

y = 200.

Thus, to use up al the eggs and cream, 150 quarts of Vanilla and 200 quarts of Mocha should be produced.
