C: She is incorrect because she shaded a temperature of −°.

Answer:

t=24+41=65

Step-by-step explanation:

The value of t>24 and is 41 more than 24. So 24+41=t.

24+41=65, so t=65.

The Length of FD = 26 cm

According to the given information

FE = FC = 12cm

As FE, FC both are radius of circle

The tangent segments to a circle from a external point are equal

Hence

CD = ED

13x - 16 = 4x + 11

13x - 4x = 11 + 16

9x = 27

x = 27/9

x = 3

CD = 13x - 16

     = 13 × 3 - 16

     = 23 cm

ED = 4x + 11

     = 4 × 3 + 11

     = 23 cm

In Triangle FED

FE is perpendicular to ED

According to Pythagoras Theorem

[tex]FD^{2}= FE^{2}+ED^{2}[/tex]

       = [tex]12^{2}+ 23^{2}[/tex]

There were 425 guests at a hotel. 170 guests ordered food. 40 percentage of the guests ordered food.

A percentage is a fraction of a whole in mathematics, which is denoted by the symbol per 100. A single unit out of a hundred, or one hundredth of something, is represented as a single percent, such as 1%. The Latin phrase per centum, which means by the hundred, is where the word percent originates. Percentage does really refer to a hundredth or 1/100 of something.

Given,

Total number of guests = 425

Guest who ordered food = 170

For percentage,

Value/ Total × 100%

170/425 × 100%

0.4 × 100%

Answer:

-1/4

Step-by-step explanation:

A reciprocal is simply defined as the inverse of a value or a number. So if we have a fraction of - 4/1 we can just flip the numerator and the denominator to get -1/4.

The length of one side is 20 ft and the other side of the yard is 33 ft.

Let the length of the side opposite to the house be x ft.

We know that the yard to be fenced is rectangular. Hence the opposite sides of the yard are going to be equal.

It is given that the side opposite to the wall is 13 ft less than the length f the other two sides.

Hence the length of the side adjacent to the house will be

(x + 13) ft

The fencing needs to be done on these three sides. We already know that the length that has been fenced is 86 ft.

Hence, we get

x  +  x + 13  +  x + 13  =  86

or, 3x + 26 = 86

or, 3x = 86 - 26

or, 3x = 60

or, x = 60/3

or, x = 20.

Hence the length of one side is 20 ft and the length of the other side is

20 + 13

= 33 ft.

By using probability, it can be calculated that

Probability that when two balls are selected at random with no replacement , both are green = 0.357

What is probability?

At first it is important to know about probability of an event.

Probability gives us the information about how likely an event is going to occur

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.

Probability of any event is greater than or equal to zero and less than or equal to 1.

Probability of sure event is 1 and probability of unsure event is 0.

Step-by-step explanation:

The equation of the line that passes through the point (−11,−14) is y = x - 3.

What is the slope of the line?

A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).

We have,

The line that passes through the point (−11,−14)

With Slope (m) = 1,

The general equation of a straight line is

y = mx + c,

where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

so here,

y = mx + c,

(-14) = 1(-11) + c

c = -14 + 11

c = -3

The equation becomes:

y = x - 3.

Hence, the equation of the line that passes through the point (−11,−14) is

Answer:

Step-by-step explanation:

Answer:

  12 3/4 -9f

Step-by-step explanation:

You want the simplified form of the expression 12-3/4(8f-5/3+4f+2/3).

We can simplify inside parentheses first. This consists of combining like terms.

  = 12 -3/4((8+4)f +(-5/3+2/3)) = 12 -3/4(12f -1)

Then the distributive property is applied, and like terms are combined (again).

  = 12 -9f +3/4

a) The linear equation is given as follows: 10x + 6y = 240.

b) The graph of the linear function is given by the image shown at the end of the answer.

The first step is defining the linear function is identifying the variables, which are given as follows:

You hope to have $240 in sales. Hats cost $10 and mittens cost $6, hence the equation is given as follows:

10x + 6y = 240.

The x-intercept is the point (x,0), hence:

10x = 240

x = 24.

The y-intercept is the point (0,y), hence:

6y = 240

y = 40.

Then the line is traced connecting the points (0,40) and (24,0), with only positive values, as they represent countable amounts.

If you take a number, times by 3 then add 5, you get (3x + 5).

If you take the same number and times by 7 then subtract 8, you get (7x - 8).

3x + 5 = 7x - 8

Subtract 3x from both sides:

The value of x from the given isosceles triangle GHJ is 5.

Isosceles triangles are those triangles that have at least two sides of equal measure and two base angles are equal.

In the given isosceles triangle GHJ, GJ=GH, ∠G=38° and ∠J=(14x+1)°.

Since, sides GJ=GH

∠J=∠H

Now, ∠G+∠J+∠H=180° (Angle sum property of a triangle)

⇒ 38°+(14x+1)°+(14x+1)°=180°

⇒ 28x+40°=180°

⇒ 28x=140°

⇒ x=140/28

⇒ x=5

The constant of proportionality in the inverse variation is 79.2

Constant of proportionality is defined as the constant value of the ratio between two proportional quantities. Two varying quantities are said to be in a relation of proportionality when, either their ratio or their product yields a constant. The value of the constant of proportionality depends on the type of proportion between the two given quantities:

This is often determined because of the formula used.

Given that the variation here is an inverse variation.

y ∝ 1/ x

y = k / x

k = y₁x₁ = y₂x₂ = y₃x₃

The perimeter of the triangle passing through the points A, B, C is 27.5 cm.

A triangle's perimeter and side lengths are measured in the same unit. If the sides' lengths are measured in a different unit, first convert them to that unit. Example 1: Calculate the triangle's perimeter from the information provided. A perimeter is a closed path that encloses, surrounds, or delimits a one-dimensional length or a two-dimensional shape. The circumference of a circle or an ellipse is its outermost boundary.

There are many uses in real life for perimeter calculations. The length of fence needed to enclose a yard or garden is known as the calculated perimeter.

From the figure,

The triangle is passing through the points A(4, 0), B(-6, 5), C(3, 3)

By using distance formula, we have to calculate the lengths of AB, BC, CA

Length of AB=√(-6-4)²+(5-10)²

=√125

Length of BC=√(3+6)²+(3-5)

=√85

Length of CA=√(3-4)²+(3-10)²

=√50

The perimeter of a triangle=AB+BC+CA

=√125+√85+√50

Step-by-step explanation:

To start, we are told that the service fee of 5.50 is added to the set price per ticket. So we can automatically eliminate B and D

Now, to find how much it costs per ticket, we have to divide 108.00 by 5 since we are told that it costs $108 to buy 5 tickets

108.00/5 = 21.60

The bijection could be defined from the set of numbers and it is proved.

We can define a bijection f from S to T as follows: for any integer x in S, let f(x) = x + 1.

To show that f is a bijection, we need to prove that it is both injective and surjective.

To prove that f is injective, suppose f(x) = f(y) for some x, y in S. Then x + 1 = y + 1, which means x = y. Thus, f is injective.

To prove that f is surjective, let y be an arbitrary element of T. Since y is odd, we can write y = 2n + 1 for some integer n. Now consider the element x = 3n in S. We have f(x) = x + 1 = 3n + 1 = y, so f is surjective.

Therefore, f is a bijection from S to T, so |S| = |T|.
