Bobby spent $20 out of $75 of his monthly allowance on paintbrushes.

What is monthly allowance?

Giving someone money on a regular basis to help them pay for the things they need is known as giving them an allowance.

Main Body:

total monthly allowance = $75

Now Bobby spent 40% on his art supplies,

which means we need to calculate 40% of 75.

⇒(40/100)*75

⇒30

so Bobby spent $30 on art supplies.

now according to question,

Bobby spent 2/3 on paintbrushes

⇒2/3 of art supplies

⇒(2/3 )*30

⇒$20

Hence Bobby spent $20 on his paintbrushes.

In a triangle ABC the value of side a is 13.12 cm.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know in a ΔABC, a/sinA = b/sinB = c/sinC.

GIven, In a ΔABC A = 29°, B = 36°, b = 15.8 cm.

∴ a/sinA = b/sinB.

a/sin(29°) = 15.8/sin(36°).

a/0.49 = 15.8/0.59.

a = (15.8×0.49)/0.59

a = 7.742/0.59.

a = 13.12.

Step-by-step explanation:

The value of f(10) = 107 and f(-3) = 16.

The function is defined as in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). An example of this would be y=x2. You only get one output for y if you enter anything for x. Considering that x is the input value.

Given that f(x)=x² + 7

We do determine the values of F (10) and F(-3)

Now f(10)

= (10)2 +7

= 100 +7

= 107

Now f(-3)

= (-3)2 +7

= 9 +7

= 16

Therefore the value of f(10) = 107 and f(-3) = 16

0.8d

d - 0.2d

Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

In this case, the cost of the item is d. Since there's a 20% discount, the new cost will be:

= d - (20% × d)

= d - 0.2d

= 0.8d

Set operations are the operations that are applied on two or more sets to develop a relationship between them.

Let mathematics = M, physics = P, chemistry = C.

20 + n(M∩C) + 24 - 3n(C∩P∩M) = 32

n(M∩C) = 3n(C∩P∩M) - 12 - *

We know,

n(M∪P∪C) = n(M) + n(P) + n(C) - n(M∩P) - n(M∩C) - n(C∩P) + n(C∩P∩M)

Answer:

x = 5

Step-by-step explanation:

I'm going to assume that this is asking you to graph in Slope-Intercept form, but if I am mistaken, comment on my answer and I will happily change it.

Slope-Intercept form:

y = mx + b

You leave y and x as variables, while m and b are to be substituted for slope and y-intercept. y-intercept is when x=0, where a point on a line is on the y axis.

To help you learn, for example, we have an equation is slope-intercept form:

y = 8x + 3

In this case, the slope is 8 and the y intercept is 3 as m is the slope and b is the y-intercept.

The slope is the steepness of the graph. The value of the slope is how much the y-value increases if the x-value increases by 1.

We can find the slope from 2 points using this formula:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we plug in our points into the formula.

[tex]\frac{-2-3}{5-5}[/tex]

Simplify.

[tex]\frac{-5}{0}[/tex]

Anything divided by 0 is undefined. This means the line we are graphing is completely vertical, known as undefined. We can only get this if the x value stays the same no matter what. In this case, the x value stays the same when the y value changes, meaning a undefined slope.

We have a special case here. If the slope is undefined, we do not use y = mx+b. Instead, we use:

x = what the x values of the 2 points are

x values of both points: 5

x = 5

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another. In mathematics, inequalities specify the relationship between two non-equal values. Equal does not imply inequality. The "not equal symbol ()" is typically used to indicate that two values are not equal. The expression 5x 4 > 2x + 3 resembles an equation, but the equals sign has been replaced by an arrowhead. It is an illustration of inequality. This shows that the left part, 5x 4, is bigger than the right part, 2x + 3.

Since the total number of people is at least 28, then the total number of people must be 28 or more, so

Now,

These ratios are equivalent: 6: 3, x: 12, and 18: y.

Ascertain the values of x and y.

Given that all ratios are equal.

so we obtain;

⇒ 6 : 3 = x : 12

⇒ 6 / 3 = x / 12

⇒ 6 × 12 / 3 = x

⇒ x = 24

And, ⇒ 6 : 3 = 18 : y

The fraction 3/5 fits into 2 1/5 more than once. The quotient is more than one.

We are given two fractions. The first fraction is 3/5, which is a simple fraction. The second fraction is 2 1/5, which is a mixed fraction. We will first convert the mixed fraction into a simple fraction.

F = 2 1/5

F = (2*5 + 1)/5

F = 11/5

We need to find out if the quotient is more or less than one. So we will divide the second fraction by the first fraction. Let the quotient be represented by the variable "Q".

Q = (11/5)÷(3/5)

Q = (11/5)×(5/3)

Q = 11/3

0.1367 percent of randomly chosen cookies will weigh less than 14 grams.

Given data;

Is it possible to calculate the likelihood that a randomly selected cookie weighs less than 14g using the information provided above?

Let,

X = Average cookie weight in a pack of 30

E (X) = μ = 15

Var (X) = σ²/n

           = 1²/30 =  0.0333

⇒ Standard Deviation (X) = √0.0333 = 0.1826

P(X ≤ 14.8) = (X-15 / 0.1826 < 14.815/0.1826)

= P(14.815 - 0.1826)

= P(Z-1.1)

= 0.1367

Hence, the probability that a randomly selected cookie has a weight less than 14g is 0.1367

ΔFDH is similar to ΔFDE by angle angle angle axiom of similarity.

Now using the properties of similar triangles we can say that :

FG / DF = GH / DE

Now let us consider the length of GF be x.

Therefore DE = x

Now using the properties of similar triangles and substituting the values we get:

The transformation f(x)—>f(1/3x) due to the graph of f(x), will be dilation horizontally and vertically.

What is Transformation of Function?

Transformation of functions refers to the graph's curve moving to the left, right, up, or down, expanding, contracting, or reflecting. Just dilation, out of these three transformations, alters the size of the original shape; the other two only adjust the position.

A translation happens when each point on a graph (which represents a function) travels in the same direction and by the same amount. There are two kinds of function translations.

Stretching or compressing is a dilation. The x-values on a graph are all scaled up by the same amount when a dilation that is parallel to the x-axis occurs. The y-values are all increased by the same scale factor if it is dilated parallel to the y-axis.

f(x) to become f(1/3x), Then it will go dilation "vertically and horizontally".
