We can calculate the net yard as adding the two events in respect to the same reference value.
The first event is gaining 14 yards, so we have a=14.
The second event is losing 20 yards, which according to our reference is a negative value: b=-20.
Then, we can calculate the net effect as:
[tex]N=a+b=14+(-20)=14-20=-6[/tex]This correspond, as it has a negative value, to a loss of 6 yards.
Answer: the total change is 6 yards lost.
-2/2 in simplest form is -1, right?
Answer:
Yes
Step-by-step explanation:
Yes, dividing a negative number by a positive number will equate to another negative number.
Applying this logic, -2 divide by 2 is simply -1
If x and 2x-15 represent the measure of the acute angles of a right triangle, find the value of x.
In a right triangle, the measure of acute angles is represented by x and 2x -15 then the value of x is equal to 35.
As given in the question,
In a right triangle,
One of the angle is of measure 90°.
Other two angles are acute angles.
Measure of two acute angles are given as x and 2x -15.
Sum of the three angles in a triangle is 180°.
x + 2x -15 + 90° = 180°
⇒3x +75° = 180°
⇒ 3x = 105°
⇒ x = 35°
Therefore, in a right triangle, the measure of acute angles is represented by x and 2x -15 then the value of x is equal to 35.

6.Which of the following represents a graph with a rate of change of ?
Solution:
The rate of change of a graph is the same as the slope of the graph.
The graph that has a rate of change of 1/2 is the graph with a slope of 1/2.
To calculate the slope of a graph,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Considering two clear points from graph C, picking the points (2,-1) and (4,0)
[tex]\begin{gathered} \text{where} \\ x_1=2 \\ y_1=-1 \\ x_2=4 \\ y_2=0 \\ \\ \text{Substituting these values in the formula to get slope,} \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{0-(-1)}{4-2} \\ m=\frac{0+1}{4-2} \\ m=\frac{1}{2} \end{gathered}[/tex]Therefore, the graph that represents a rate of change of 1/2 is the graph of option C.

ANSWER:
25 fish
STEP-BY-STEP EXPLANATION:
We have been given that the volume of a fish tank is 50 ft^3 and the density is 0.5 fish/ft^3. To find the number of fish in the tank, we need to multiply the volume of the tank by the density. Just like this:
[tex]\begin{gathered} n=50ft^3\cdot0.5\frac{fish}{ft^3} \\ n=25\text{ fish} \end{gathered}[/tex]Therefore, there are 25 fish in the tank.

Answer:
x = 30°, y = 80°
x = 40°, y = 50°
Step-by-step explanation:
Alternate Interior Angles Theorem
If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent.
Therefore, as the two horizontal lines are parallel:
⇒ x = 30°
Exterior Angle Theorem
The exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles of the triangle.
⇒ y = 50° + x°
⇒ y = 50° + 30°
⇒ y = 80°
-----------------------------------------------------------------------------------
Vertical Angles Theorem
When two straight lines intersect, the opposite vertical angles are congruent.
Therefore, the angles marked red on the attached diagram are equal.
This means that the two triangles outlined in green are similar.
If two triangles are similar, their corresponding angles are congruent.
⇒ x = 40°.
Interior Angles of a Triangle
The interior angles of a triangle sum to 180°.
Therefore:
⇒ 90° + x + y = 180°
⇒ 90° + 40° + y = 180°
⇒ 130° + y = 180°
⇒ y = 50°
Solve the polynomial inequality and graph the solution set on a number line. Express the solution set in interval notation.
First we have to find the values in which each factor equals zero.
In the first factor is going to be 5
In the second factor is going to be 7
Then we divide the number line by three parts
First part: Numbers less than 5
Second part: Numbers between 5 and 7
Third part: Numbers greater than 7
We choose any number belonging to each interval
First part: zero (0) because is less than 5
Second part: 6 because is a number between 5 and 7
Third part: 8 because it is a number greater than 7
Then we replace the numbers in the factors and operate
First part: (0-5)*(0-7) = (-5)*(-7)= 35 ( positive)
second part: (6-5)*(6-7) = (1)*(-1)= -1 ( negative)
third part: (8-5)*(8-7) = (3)*(1)= 3 ( positive)
Since we are searching for numbers that replaced in the equation give us negative results the intervals for the inequality must be

how much interest earned on 124 ar 4% for one year
The principal amount is 124
The interest rate is 4% [in decimal, 4% is 4/100 = 0.04]
To get the interest amount, we mutiply the principal with the interest rate (in decimal).
The answer is:
[tex]124\cdot0.04=4.96[/tex]find the zeros of the function.f(x) = 3x^2 + 6
f(x) = 3x^2 + 6
0 = 3x^2 + 6 (Replacing f(x) by 0)
-6 = 3x^2 (Subtracting 6 from both sides of the equation)
-6/3 = x^2 (Dividing by 3 on both sides of the equation)
-2 = x^2 (Dividing)

Since the angles given by the equation are alternate interior angles the are the same, that is
9x + 41 = 13x - 15
Using this equation, we can find x value
Step 1Rearraging the equation so the terms with the unkown variable x are on the right side and the other ones on the left side:
9x + 41 = 13x - 15
↓ substracting 9x both sides
41 = -9x + 13x - 15
41 = 4x - 15
↓ adding 15 both sides
41 + 15= 4x
56 = 4x
Step 2Solving the equation for x
56 = 4x
↓ dividing by 4 both sides
56/4 = x
14 = x
Answer A: x = 14
Now we want to find angle 4. Since it makes a straight line with the angle given by the expression 13x - 15, then their addition should be equal to 180°:
∡4 + 13x - 15 = 180
We want to find ∡4, and we do know the value for x, so, using the expression we can find it.
Replacing x by 14:
∡4 + 13x - 15 = 180
↓replacing x = 14
∡4 + 13 · 14 - 15 = 180
∡4 + 182 - 15 = 180
∡4 + 167 = 180
We follow the same previous steps to find ∡4
Step 1Rearraging the equation so the terms with the unkown variable ∡4 are on the left side and the other ones on the right side:
∡4 + 167 = 180
↓ substracting 167 both sides
∡4 = - 167 + 180
∡4 = 13°
Step 2:We already found it using step 1 so step 2 is not neccesary to be followed
Answer B: ∡4 = 13°

Therefore, the second table must be

Round to nearest tenth is 0.9 in percentage .
What does the % mean?
A percentage is a figure or ratio that can be stated as a fraction of 100 in mathematics. If we need to determine a percentage of a number, multiply it by 100 and divide it by the total. So, a part per hundred is what the percentage refers to. Per 100 is what the word percent means. The letter "%" stands for it.By dividing the value by the sum of the values, and then multiplying the outcome by 100, one can get the percentage. The formula for calculating percentage is (value/total value)100%.Percent is derived from the Latin word per centum, which means "by the hundred."24×3.5% = 0.84
so round to nearest tenth is 0.9.
