Answer:

8%

Step-by-step explanation:

Use formula

[tex]\text{Percent increase}=\dfrac{\text{New value - Old value}}{\text{Old value}}\cdot 100\%[/tex]

Old value = $16,500

New value = $17,820

Hence, the percent increase is

[tex]\dfrac{\$17,820-\$16,500}{\$16,500}\cdot 100\%=\dfrac{\$1,320}{\$16,500}\cdot 100\%=\dfrac{8}{100}\cdot 100\%=8\%[/tex]

0.08 is equal to 8%, the percent increase in the value of the property is 8%.

First, calculate the increase in the value of the property:

increase = 17820 - 16500

        = 1,320

Next, calculate the percent increase by dividing the amount of the increase by the original value of the property and multiply by 100%:

percent increase = (1320 / 16500) * 100

percent increase = 0.08

Since 0.08 is equal to 8%, the percent increase in the value of the property is 8%.

Answer:

30

Step-by-step explanation:

y varies directly with x, so:

y = kx

When x = n, y = 180.

180 = kn

When x = 5, y = n.

n = 5k

Solve for k in the first equation:

k = 180 / n

Substitute into the second equation:

n = 5 (180 / n)

n = 900 / n

n² = 900

n = 30

Hey!

Part A:

30d (30 * d)

---------------------------------------

Part B:

Using the expression 30d we can solve how much time Brianna spent playing piano.

30(2) = 60 minutes (1 hour) in 2 days

30(4) = 120 minutes (2 hours) in 4 days

30(10) = 300 minutes (5 hours) in 10 days

---------------------------------------

Hope This Helped! Good Luck!

Answer with Step-by-step explanation:

Brianna practices the piano 30 minutes per day.

1 hour = 60 minutes

or 1 minute = 1/60 hour

30 minutes = 30/60 hours

                   = 0.5 hour

i.e. Brianna practices the piano 0.5 hours per day.

a. 0.5 hours per day means

   0.5d hours in d days

Expression for the number of hours she practices in d days is: 0.5d

b.  Number of hours she practices in 2 days = 0.5×2=1 hour

    Number of hours she practices in 4 days = 0.5×4=2 hours

    Number of hours she practices in 10 days = 0.5×10=5 hours

No, angle B or angle C can't be obtuse.

It is given that:

Angle A in triangle ABC is obtuse.

This means that:

∠A > 90°

Now, let us assume that:

Angle B is obtuse.

i.e. ∠B > 90°

Hence, we get that the sum of two angle is greater than 180 degree.(i.e. ∠A+∠B > 180° )

hence, the sum of all the three angles will be greater than 180 degrees.

But we know that in order to form a triangle the sum of all the three angles must be equal to 180 degree.

No, angle B and angle C cannot be obtuse if angle A is obtuse because the sum of angles in a triangle is always 180 degrees, and if one angle is obtuse, the other two must be acute to satisfy this rule.

We have,

In a triangle, the sum of all angles is always 180 degrees.

If angle A in triangle ABC is obtuse, it means it measures more than 90 degrees (greater than a right angle).

For the sum of the angles to be 180 degrees, angles B and C must be acute (measuring less than 90 degrees).

This is because if either angle B or angle C were obtuse, the sum of the angles would exceed 180 degrees, which is not possible in a triangle.

So, angle B and angle C cannot be obtuse if angle A is obtuse.

Thus,

No, angle B and angle C cannot be obtuse if angle A is obtuse because the sum of angles in a triangle is always 180 degrees, and if one angle is obtuse, the other two must be acute to satisfy this rule.

Shift 1 units towards left and then stretch vertically 3 times.

Step-by-step explanation:

We are given that a parent function

[tex]y=x^2[/tex]

After transformation, we get a graph [tex]y=3(x+1)^2[/tex]

We have to find that how the parent function transformed to produce the graph of [tex]y=3(x+1)^2[/tex]

The parent graph is shifted  1 unit towards left by the rule of transformation

x=1.4 y=2.8

Step-by-step explanation:

Lets substitute y with 2x. We get: 1.85x+7.4x=12.95.

Simplifying by combining x: 9.25x=12.95

Then you just divide 12.95 by 9.25: x=1.4

Now for y. We know why is 2x so we just have to multiply x by 2: y=2x, y=2.8.

Answer:

18,0 the time it takes or the helicopter to reach the ground.

Step-by-step explanation:

if you look at the table, it slowly is decreasing, therefore it is going towards the ground.

Answer:  The correct option is

(D) (18,0) the time it takes for the helicopter to reach the ground.

Step-by-step explanation:  Given that the table shown in the picture gives the  number of feet a helicopter flies above the ground as a function of time.

We are to find and interpret the meaning of the x -interpret in this scenario.

From the table, we note that

the graph of function f(x) will pass though the points (0, 18) and (2, 16).

So, the slope of the line graph of f(x) is

[tex]m=\dfrac{16-18}{2-0}=\dfrac{-2}{2}=-1[/tex]

Since the line passes through the point (0, 18), so its equation will be

[tex]y-18=m(x-0)\\\\\Rightarrow y-18=-1\timesx\\\\\Rightarrow y=-x+18.[/tex]

Now, to find x-intercept, we need to substitute y = 0 in the equation of the line.

So, at y = 0, we get

[tex]0=-x+18\\\\\Rightarrow x=18.[/tex]

Therefore, the required x-intercept is (18, 0) and is shows that the time taken by the helicopter to reach the ground is 18.

Thus, option (D) is CORRECT.

In order to get the answer to this question you will have to find the common factor and then divide the numerator and denominator by the common factor to get the answer.

[tex]\frac{20}{10}[/tex]

[tex]CF=10[/tex]

The water level in the tank decreased from 8 cm to 4 cm. This represents a decrease of 4 cm or a 50% decrease.

The decrease in water level in the tank is calculated by finding the difference between the initial level and the final level. In this case, the initial level is 8 cm and the final level is 4 cm. The difference between these two levels is 4 cm.

To calculate the percent decrease, divide the decrease in level by the initial level and then multiply by 100%. So, in this case, the percent decrease in water level is (4 cm / 8 cm) * 100% = 50%.

The percent decrease of water in the tank from noon to several hours later is therefore 50%.
