It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

3,

The triangle is an equilateral triangle.

Value of all the angles = 60°

All sides are equal.

Now,

46 = 16 + y

y = 46 - 16

y = 30

Now,

The sum of the three angles of the triangle is 180 degrees.

80 + 60 + (60 - x) = 180

140 + 60 - x = 180

200 - 180 = x  

x = 20

4.

There is an equilateral triangle.

5y = 20

y = 4

There is an isosceles triangle.

Where two sides are equal and the angle opposite to the equal sides are also equal.

This means,

(180 - 60) + x + x = 180

120 + 2x = 180

2x = 180 - 120

x = 60/2

x = 30

Thus,

3.

The value of x and y is 20 and 30.

4.

The value of x and y is 30 and 4.

Based on the definition of complementary angles, the value of d is: 10.

Complementary angles can be described as two angles that have a sum of 90 degrees when added together.

Given that the two angles, 24° and (7d - 4)°, are complementary angles, it implies that their sum will give a measure of 90°. Therefore, to find the value of d, the following equation would be created based on the definition of complementary angles:

24 + (7d - 4) = 90

Open the parentheses:

24 + 7d - 4 = 90

Combine like terms:

7d + 20 = 90

Subtract 20 from both sides

7d + 20 - 20 = 90 - 20

7d = 70

Divide both sides by 7

7d/7 = 70/7

d = 10

The value of d is: 10.

95% confidence interval of mean  is between (16.91, 19.89)

the mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean

Data dispersion in regard to the mean is quantified by a standard deviation, or. Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high.

Given the sample size of 35, the mean x value is 18-4.

Standard deviation S=4.5

C = 95%

a = 1 - c = 0.05

From standard deviation from z table[tex]z_{0.05}[/tex] is 1.96 we know formula for confidence interval is

The system of equations is 4.25x + 2y = 53.75, y = x + 5, and the number of bangles and breakfast sandwiches Amir bought is 12 and 7 respectively.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given:

Amir spent a total of $53.75 on breakfast sandwiches and bagels

Each breakfast sandwich costs $4.25, and each bagel costs $2.00

Calculate the equation as shown below,

4.25x + 2y = 53.75

Here, y = number of bangles and x = number of sandwiches,

y = x + 5

Solve the equation to get the values,

x  = 7 and y = 7 + 5 = 12

Therefore, the system of equations is 4.25x + 2y = 53.75, y = x + 5, and the number of bangles and breakfast sandwiches Amir bought is 12 and 7 respectively.

Answer: B

Step-by-step explanation:

The solution to the equation is x = -28/9.To solve the equation 2 1/7 + 3/7(3x - 5) = -4, let's break it down step by step.

Step 1: Convert the mixed number 2 1/7 to an improper fraction. Multiply the whole number (2) by the denominator (7), then add the numerator (1). This gives us (2 * 7 + 1) / 7 = 15/7.

Step 2: Distribute the 3/7 to the terms inside the parentheses. Multiply 3/7 by each term, which gives us (3/7) * 3x = 9x/7 and (3/7) * (-5) = -15/7.

Step 3: Substitute the converted mixed number and the distributed terms back into the equation. The equation becomes 15/7 + 9x/7 - 15/7 = -4.

Step 4: Combine like terms. Add the fractions with the same denominator: (15/7 - 15/7) + 9x/7 = -4. The fractions cancel each other out, leaving us with 9x/7 = -4.

Step 5: Isolate the variable. Multiply both sides of the equation by the reciprocal of 9/7, which is 7/9. This gives us (7/9)(9x/7) = (7/9)(-4). The 7/9 on the left side cancels out, leaving x = (-28/9).

Answer:

each girl scored 1 point and each boy scored 20 points.

Step-by-step explanation:

Let $g$ be the number of points scored by each girl and $b$ be the number of points scored by each boy. We can set up the following system of equations:

$$3g + 2b = 43$$

$$3g - 2b = 11$$

We can solve this system of equations using substitution. From the first equation, we have that $3g = 43 - 2b$. Substituting this expression for $3g$ into the second equation gives:

$$3(43 - 2b) - 2b = 11$$

Solving for $b$, we get:

$$129 - 6b = 11$$

$$6b = 118$$

$$b = 19.5$$

Since $b$ must be a positive integer, the only possible value for $b$ is $20$. Substituting this value into the first equation, we get:

$$3g + 2(20) = 43$$

Solving for $g$, we get:

$$3g = 3$$

$$g = 1$$

Therefore, each girl scored $1$ point and each boy scored $20$ points.

The tangent line to the graph of f(x) = 2e²ˣ-5 at the point (2, 1/e) is given by y=2e⁴+1-2e⁵/e

Two or more expressions with an Equal sign is called as Equation.

The equation of the tangent line to the graph of f(x) = e²ˣ-5

To find the Equation of a tangent to any curve you must first find the derivative of the function.

y = e²ˣ-5

y'=2e²ˣ

sub x=2 into derivative function

y'(2)=2e⁴

so we have found that the tangent line is y=2e⁴+c

now we have to sub in the point and solve for c:

1/e=2e⁴+c

c=1/e-2e⁴

c=1-2e⁵/e

c=0 when x is 2.

The equation of tangent to the line is y=2e⁴+(1-2e⁵)/e

Hence,  the equation of the tangent line to the graph of f(x) = 2e²ˣ-5 at the point (2, 1/e) is given by y=2e⁴+1-2e⁵/e
