The sum of the measures of angles D and E is (3x + 25)° greater than the measure of angle F. which is the correct answer would be an option (C).

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.

The given Triangle DEF which has

∠D = 3(x+10)°

∠E = (2x+15)°

∠F = 2(x+10)°

The sum of the measures of angles D and E :

3(x+10)° + (2x+15)°

3x + 30 + 2x + 15

5x + 45

Difference between the sum of the measures of angles D and E and the measure of angle F :

5x + 45 - 2(x+10)

Answer:

Whole banana = 6/6

Step-by-step explanation:

Given information,

→ Kendyl ate 4 pieces.

→ Adison ate 2 pieces.

Now the total number of pieces,

→ 4 + 2

→ 6 banana pieces

Fractional representation is,

→ Kendyl = 4/6

→ Adison = 2/6

→ Whole banana = 6/6 = 1

Hence, the answer is 6/6.

The Graph C shows the solution to this system of inequalities in the coordinate plane.

When mathematical expressions are compared, with non-strict equality, then such mathematical statements are called mathematical inequalties.

A collection of inequalities for which we consider common solution for all inequalities is called a system of inequalities.

We are given that

3y > 2x + 12

2x + y ≤ - 5

Therefore, solving it;

x < 3(y - 4)  / 2

y > 2 (x + 6)  / 2

2x + y< -5

x> -5

So,

x < 3(y - 4)  / 2  

Here it shows dotted ascending line attached through x=-6

This means x=--6 and y = 0

This x>-5 shows boundary dotted vertical line through -5

Which means x = -5 y = 0

If it had been x ≥ -5 it would have been solid boundary line.

The vertices of both show (-5,1) so the correct option is C.

The volume of the cylinder is 602.9 cm³

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

We need to find the volume of the cylinder whose height is 3 cm and diameter is 16 cm.

Radius =16/2=8 cm.

The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder.

V = πr²h

where 'r' is the radius of the base (circle) of the cylinder

'h' is the height of the cylinder

As per the given figure,

The radius of a cylinder is 8 cm and the height of the cylinder is 3 cm.

V = 3.14×8²×3

=3.14×64×3

=602.88=602.9 cm³

Hence, the volume of the cylinder is 602.9 cm³

The numeric values for each expression in this problem are given as follows:

a. g(g(g(1))) = 1.

b. f(f(f(2)) = 1.

c. f(f(g(2))) = 2.

d. g(f(g(4))) = 2.

The numeric value for each expression is obtained using the compositions, and also the numeric values given from the tabke,

As an example, from the table, we have that when x = 1, g(x) = 4, hence:

g(1) = 4.

Hence:

g(g(g(1))) = g(g(4)) = g(3) = 1.

The circle symbol represents composition, meaning that the expressions are similar to item a.

Thus the numeric value in item b is obtained as follows:

f(f(f(2)) = f(f(4)) = f(5) = 1.

The numeric value in item c is obtained as follows:

f(f(g(2))) = f(f(5)) = f(1) = 2.

The numeric value in item d is obtained as follows:

g(f(g(4))) = g(f(3)) = g(6) = 2.

Answer:

The equation g² + 42 = 0 has two real solutions.

To solve this equation, we can start by subtracting 42 from both sides to get g² = -42. Then, we can take the square root of both sides to get |g| = √42. Since the square root of a number is positive, this means that g = √42 or g = -√42. These are the two solutions to the equation.

Kim's total salary for each month is given as follows:

Kim's salary is divided into two earnings, as follows:

Kim's sales were $16,100 for last month, hence her commission is found applying the proportion as follows:

0.12 x 16100 = $1,932.

(the proportion is obtained multiplying the decimal equivalent of the percentage by the total amount to obtain the desired amount).

Then, adding to the fixed salary of $1,010, her total salary for the past month is obtained as follows:

The inequality which corresponds with the graph below is x + y ≤ 0.

A mathematical expression in which the sides are not equal is referred to as being "inequality." An inequality, in its most basic form, is a comparison of any two values that shows that one value is less than, greater than, or equal to the value on the other side of the equation.

Less than (<), greater than (>), less than or equal (≤), greater than or equal (≥), and the not equal symbol (≠) are the inequality symbols.

Comparing numbers and identifying the range (or ranges) of values that meet the specifications of a given variable are both done using inequalities.

The equation of the above straight line is

y = −x

or

x + y=0

Now the shading in the above graph is towards the negative part (where x is negative).

Also the line is dark and not dotted. This indicates that the points on the line are part of the inequality.

Thus, the inequality which corresponds with the graph below is x + y ≤ 0.

The coordinates of the point P on the directed line segment that partitions the segment into a ratio of 3 to 2 is the ordered pair (4.2, -0.2).

In this exercise, line ratio would be used to determine the coordinates of the point P on the directed line segment that partitions the segment into a ratio of 3 to 2.

Mathematically, line ratio can be used to determine the coordinates of the point P and this is modeled by this mathematical expression:

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

Substituting the given parameters into the line ratio formula, we have;

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

P(x, y) = [(3(4) + 2(-2))/(3 + 2)],  [(3(-3) + 2(4))/(3 + 2)]

P(x, y) = [(27 - 4)/(5)],  [(-9 + 8)/5]

P(x, y) = [21/5],  [-1/5]

P(x, y) = [4.2, -0.2]

The payment amount rate required to pay off the loan in 2 years is k = $4,266.67 and the total interest paid during the two-year period is $2,142.66. This is calculated by using the formula for continuous compounding to solve for k and the formula for calculating interest to solve for I.

1. Calculate the payment rate required to pay off the loan in 2 years:

k = P/(1 - e^(-rt))

= 7506/(1 - e^(-0.15*2))

= 7506/(1 - 0.8698)

= 4,266.67

2. Calculate the total interest paid during the two-year period:

I = P(e^(rt) - 1)

= 7506(e^(0.15*2) - 1)

= 7506(1.3302 - 1)

= 2,142.66

Payment rate required to pay off the loan in 2 years: K = $5,062.89. The amount of interest paid during the 2-year period is $1,506.11.

Correct responses:

AB = 1

BC = √2

The 45°–45°–90° triangle theorem is one that states that the ratio of the lengths of the sides of triangles having interior angles of 45°, 45°, 90° is expressed as 1 : 1 : √2

We know that the lengths of the legs of an isosceles triangle are equal. Now, the legs of the given isosceles right triangle in the attached file are AB and AC.

Thus, we can say that, AB = AC

If the length of AB s 1 unit, then we have;

AB = AC = 1

Using Pythagoras theorem, we have;

BC² = AB² + AC²

Which gives; BC = √2

Therefore, by plugging in the length of AB = AC = 1, we have;

AB = 1

AC = 1

BC = √2 ≈ 1.414

The above values are in the ratio 1 : 1 : √2, which now corresponds with the 45°-45°-90° triangle theorem.
