Proportionately, if Lexi uses 360 g of flour, the quantity of blueberries she must use is 150 g of blueberries.

Proportion describes the two ratios equated to each other.

Proportions are fractional values between zero and one.

Recipe for making Blueberry Muffins

Ingredient  Quantity

Egg              1

Flour           120 g

Sugar         120 g

Butter          60 g

Blueberries 50 g

120 g of flour = 50 g of blueberries

The Ratio of flour to blueberries = 2.4:1

360 g of flour = 360/120 x 50

= 150 g of blueberries (360/2.4)

Thus, if Lexi uses 360 g of flour, based on the given recipe, she must use 150 g of blueberries.

Step-by-step explanation:

Please when you come across any questions including two equations of two variables, please solve that question by using the simultaneous method.

To go about that, since you would be given two equations, name one equation as "equation one" (eq 1) and the other, "equation two" (eq 2).

Right after that, make any of the variables a subject ( make it stand alone or be on one side of the equal to sign). Now, substitute that variable you've made the subject into the other equation which you didn't make any variable the subject. Solve for that, by grouping all like terms and you would realize that the final result would be the answer of one of the variables.

After getting that value, substitute that value in place of its variable. (For instance, x = 1, substitute the value which is 1 in place of x in the equation you made a variable the subject at the beginning). Solve for that equation too, and finally you would arrive at an answer or a value.

To verify that your answers are right, substitute the values in their respective variables. ( For instance, if x = 1 and y = 2, put 1 in place of x and 2 in place of y in the first equation then do same for the second equation as well). The answer would be the same as the number it has been equated to.

The number of different ways will be 108000.

Permutations are various ways to arrange things in a specific order. It can also be stated as the linear reordering of items in an already ordered set.

A first guess for the number of ways to select a committee consisting of 3 engineers, 2 physicists, and 2 computer scientists from 10 engineers, 5 physicists, and 6 computer scientists could be to simply multiply the number of ways to select each group separately:

10 choose 3 x 5 choose 2 x 6 choose 2

This would give us the number of ways to select 3 engineers out of 10, 2 physicists out of 5, and 2 computer scientists out of 6.

The number of ways can be,

N = ¹⁰C₃ x ⁵C₂ x ⁶C₂

N = 10 x 9 x 8 x 5 x 6 x 5

N = 108000

Therefore, the number of different ways will be 108000.

The measures of the angles, obtained using circle theorems are;

a = 90°, b = 12°, c = 64°, d = 54°, e = 54°, f = 48°, g = 66°, h = 32°, i = 36°, and j = 20°

Circle theorems are theorems that specify the relationships between the chords, tangents, sectors, and angles in a circle.

The linear pair angles ∠a indicates;

a + a = 2·a = 180°

a = 180°/2 = 90°

The 78° angle in the inscribed right triangle indicates;

∠b = 90° - 78° = 12°

The 32° angle at the circumference of one of the circles indicates;

Angle at the center, which nis a base angle of the large triangle = 2 × 32° = 64°

A base angle of the large triangle = 64°

∠C = A base angle of the large triangle = 64°

2·c + d = 180° (Properties of a cyclic quadrilateral)

Therefore;

2 × 64° + d = 180°

d = 180° - 2 × 64° = 54°

d = 54°

Angle ∠e = Angle ∠d = 54°

The vertex angle of the inscribed isosceles triangle in the circle with angle ∠f is; 4·b

Therefore;

The vertex angle = 4 × 12° = 48°

An angle formed between a chord and a circle is equivalent to the angle in the segment that is in the alternate side or area, therefore;

Circle theorem indicates; ∠f = The vertex angle = 48°

The base angles of the isosceles triangle = (180° - 48°)/2 = 66°

Angle ∠g = 66°

The  chord which is the base of the isosceles triangle in the circle with the angle h forms an isosceles triangle with the sides of the large triangle, such that the base angles are also ∠c = 64°

Circle theorem indicates that the vertex angle of the triangle with angle h is also 64°

Therefore, according to circle theorem; 2·h = 64°

h = 64°/2 = 32°

The vertex angle of the quadrilateral with angle 2·f is; 180° - 2·f

The vertex angle is therefore; 180° - 2 × 48° = 84°

The angle at the center is therefore; 2 × 84° = 168°

Angle ∠i is therefore;

i = 360° - 5·b - 2·f - 168°

i = 360° - 5 × 12° - 2 × 48° - 168° = 36°

5·b + 2·h + i + j = 180°

Therefore; j = 180° - (5·b + 2·h + i)

j = 180° - (5 × 12° + 2 × 32° + 36°) = 20°

To find the percent increase in price, we need to calculate the difference between the original price and the new price, and then express that difference as a percentage of the original price.

The original price of the sweatshirt was $40, and the new price is $65, so the difference is:

$65 - $40 = $25

To express this as a percentage of the original price, we divide the difference by the original price and multiply by 100:

($25 / $40) x 100% = 62.5%

Therefore, the percent increase in the price of the sweatshirt is 62.5%.

The same letter is frequently used in mathematical formulas to attempt to enforce uniformity among two variable assertions. Mathematical equations, also referred to as assertions, are used to demonstrate the equality of many academic figures. Using the outcome y + 6 = 12 as an example, the normalise divides the numbers 12 and b + 6 into 2 parts. The relationship between each symbol component and the amount of lines can be found. A symbol's meaning typically runs counter to itself.

Here,

In order to remove variables and obtain an expression for w + x + y + z, we can begin by adding the four equations. As a result, we get:

To solve the equation 3/4x + 3 - 2x = -1/4 + 1/2x + 5, we first need to simplify both sides by combining like terms:

3/4x - 2x + 3 = -1/4 + 1/2x + 5

Next, we can simplify the fractions on the right side by finding a common denominator of 4:

3/4x - 2x + 3 = -1/4 + 2/4x + 20/4

Simplifying the right side further, we get:

3/4x - 2x + 3 = 19/4 + 1/2x

Now we can isolate the variable x by moving all the terms containing x to one side of the equation and all the constants to the other side:

3/4x - 2x - 1/2x = 19/4 - 3

Combining like terms:

-5/4x = 5/4

Finally, we can solve for x by multiplying both sides by the reciprocal of -5/4:

x = -1

Therefore, the solution to the equation is x = -1.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The equations that are true for x = -2 and x = 2 are -

x² - 4 = 0 (when x = -2, this becomes 4 - 4 = 0; when x = 2, this becomes 4 - 4 = 0)

4x² = 16 (when x = -2, this becomes 4(4) = 16; when x = 2, this becomes 4(4) = 16)

The other options are not true for x = -2 and x = 2.

Specifically -

x² = -4 is not true for any real value of x, since the square of any real number is always non-negative.

3x² + 12 = 0 is not true for x = -2 or x = 2, since plugging in these values gives 12 ≠ 0.

2(x - 2)² = 0 is only true for x = 2, but not for x = -2, since plugging in x = -2 gives 2(16) ≠ 0.

The base of the exponential function (1.75) is greater than 1, this represents exponential growth. As x increases, the value of the function will grow at an increasing rate.

Exponential growth is a mathematical concept that describes a process where a quantity grows at an increasing rate proportional to its current value. In other words, the larger the quantity, the faster it grows. This leads to a graph that is characterized by a rapid upward curve that becomes steeper and steeper over time.

Exponential growth is often represented by the equation y = abˣ, where y is the final amount, a is the initial amount, b is the growth factor or base, and x is the time or number of periods.

The function f(x) = a(1+r)ˣ represents exponential growth, where "a" is the initial value, "r" is the growth rate as a decimal, and "x" is the time variable.

In this case, the initial value is 50, and the growth rate is 75%, or 0.75 as a decimal. Therefore, the equation for the function becomes:

f(x) = 50(1+0.75)ˣ

Simplifying this expression, we have:

f(x) = 50(1.75)ˣ

Since the base of the exponential function (1.75) is greater than 1, this represents exponential growth. As x increases, the value of the function will grow at an increasing rate.

To find the value of function g(x + a) - g(x), we first need to substitute g(x + a) and g(x) into the expression and simplify:

g(x + a) - g(x) = [- (x + a)^2 + 5(x + a)] - [-x^2 + 5x]

= [-x^2 - 2ax - a^2 + 5x + 5a] - [-x^2 + 5x]
