Answer:

Percentage in decrease = 10 %

Step-by-step explanation:

Given  : Original population: 1,503  and New population: 1,356.

To find : Estimate the percent of decrease.

Solution : We have given

Original population: 1,503

New population: 1,356.

Value decrease = original population - new population.

Decrease = 1,503    - 1,356

Decrease population =  147

Percentage in decrease = [tex]\frac{decrease\ value}{original}*100[/tex].

Percentage in decrease = [tex]\frac{147}{1503}*100[/tex].

Percentage in decrease = [tex]\frac{14700}{1503}[/tex].

Percentage in decrease = 9.78 %

Estimate = 10 %.

Therefore,

Percentage in decrease = 10 %

Answer:

97

Step-by-step explanation:

The digits formed by 9 and 7 (without repetition) are 79 and 97. In rounding off a number to the nearest tens, the number in the unit position is considered.

If that number is less than 5, it is changed to 0. However, where the number is above 5, 1 is added to the number in the tens place with the number in the unit place changed to 0.

Going by the above explanation, 79 rounds off to 80 while 97 rounds off to 100.

The correct model for the bank service cost based on the number of checks written during a month is f(x)=0.45x + 12.50.

The question is asking for a model that would represent the cost of a bank service based on the number of checks written during a month. The bank charges $0.45 for each check, which is a variable cost that will change depending on the number of checks, represented by x. Additionally, they also have a monthly fixed service charge of $12.50, which is paid regardless of whether or not a check is written that month.

So, the amount paid every month is $0.45 multiplied by the number of checks, plus $12.50. In function format, that will be represented as $0.45x + $12.50, which is equivalent to the option D i.e f(x)=0.45x + 12.50. So, the correct model for the situation is D.

Answer: They need 34 more days to complete the remainder of the project.

Step-by-step explanation:

Since we have given that

Number of days the work was done = 6 days

Part of work is completed in these days = 15%

If the work is done at the same rate,

then the remaining part of work is done in how many days.

Remaining part of work is 100% - 15% = 85 %

So, it becomes,

[tex]\dfrac{6}{0.15}=\dfrac{x}{0.85}\\\\x=\dfrac{6\times 0.85}{0.15}=34\ days[/tex]

Hence, they need 34 more days to complete the remainder of the project.

The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

For any triangle, the sum of the measures of the three interior angles is always 180 degrees. An exterior angle is formed by extending one side of the triangle. The sum of the measures of the exterior angle and its corresponding remote interior angles is always 180 degrees. Therefore, the measure of an exterior angle is equal to the sum of the measures of the remote interior angles.

Final answer:

The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

Explanation:

The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

For example, if one of the remote interior angles of a triangle measures 40 degrees, then the corresponding exterior angle measures 40 degrees as well. The sum of the measures of the other two interior angles would be 140 degrees, making the exterior angle equal to 40 degrees.

Therefore, the correct option that completes the statement is equal to.

The solution of the system is y = -30 and x = 30.

Here we have two equations:

y = -(4/5)*x - 6

y = -30

The second equation can be replaced in the first one, so we get:

-30 = -(4/5)*x - 6

Now we can solve that for x.

-30 + 6 = -(4/5)*x

24*(5/4) = x = 30

So the solution of the system is y = -30 and x = 30.

Heather's quadratic function must have a double root at x = -6, suggesting a function of the form y = a(x + 6)² here 'a' is a nonzero coefficient. The orientation and width of the parabola depend on the value of 'a'.

Since Heather's quadratic function represents a parabola that touches but does not cross the x-axis at x =
–6, her function must have a double root at x= –6. To achieve this, the quadratic function should be in the form y = a(x + 6), where a is a non-zero coefficient.

The function that Heather could be writing will have a vertex at the point (-6, 0), as the parabola touches the x-axis at this point. Thus, a possible function can be y = (x + 6), if we assume a coefficient of 1 for simplicity. If a is negative, the parabola will open downwards, while a positive a will make the parabola open upwards. However, the exact value of a will depend on other conditions Heather might have, such as the position of the parabola in relation to the y-axis or specific points it must pass through.

Answer:

∵ MON ≅ RTS

∴ The answer is C. RTS.

Step-by-step explanation:

When two triangles are congruent, they will have congruent pairs of vertices. Each vertex in one triangle will have a partner in the other triangle.

If we look at ΔMON, we can see it is almost like a right triangle, with:

In the next triangle, each letter has to be in the same order as the congruent vertex in ΔMON.

This triangle is ΔRTS, with:

Thus, the pairs of congruent angles are:

When we write the statement of congruence, we order the letters by their congruent pair.

∴ MON ≅ RTS

Charlie needs to apply a force in the opposite direction of the resultant vector sum of his brothers' forces. By converting the forces into Cartesian vectors based on the bearings, we can calculate the components of Charlie's required force to maintain equilibrium.

Step 1: Break down the forces into their x and y components

The force exerted by Noah can be broken down into its x and y components using the following equations:

F_x_Noah = F_Noah × cos(θ_Noah) = 8 N × cos(023°) ≈ 7.13 N

F_y_Noah = F_Noah × sin(θ_Noah) = 8 N ×  sin(023°) ≈ 3.71 N

The force exerted by Jude can be broken down into its x and y components using the following equations:

F_x_Jude = F_Jude ×  cos(θ_Jude) = 5 N × cos(155°) ≈ -4.95 N

F_y_Jude = F_Jude ×  sin(θ_Jude) = 5 N  × sin(155°) ≈ -0.58 N

Step 2: Sum the x and y components of the forces

To find the net force in the x-direction, we sum the x-components of the forces exerted by Noah and Jude:

F_x_net = F_x_Noah + F_x_Jude ≈ 7.13 N - 4.95 N ≈ 2.18 N

To find the net force in the y-direction, we sum the y-components of the forces exerted by Noah and Jude:

F_y_net = F_y_Noah + F_y_Jude ≈ 3.71 N - 0.58 N ≈ 3.13 N

Step 3: Calculate the magnitude of the net force

The magnitude of the net force can be calculated using the Pythagorean theorem:

F_net = √(F_x_net^2 + F_y_net^2) ≈ √(2.18 N^2 + 3.13 N^2) ≈ 3.74 N

Step 4: Find the angle of the net force

The angle of the net force can be calculated using the following equation:

θ_net = atan(F_y_net / F_x_net) ≈ atan(3.13 N / 2.18 N) ≈ 55.6°

Step 5: Calculate the force Charlie needs to exert

In order for Charlie to keep the toy fire truck in equilibrium, he needs to exert a force that is equal in magnitude and opposite in direction to the net force. Therefore, the force Charlie needs to exert is 3.74 N at an angle of 55.6° + 180° = 235.6° (since the net force is acting in the third quadrant).
