Answer:

D, 10.28

Step-by-step explanation:

2+2+3.14x2/2+3.14x2/2=10.28

Answer:

10.28 in

Step-by-step explanation:

r = 2in/2 = 1in

P = 2π·r + 2·l

= 2×3.14×1in + 2×2in

= 6.28in + 4in

= 10.28 in

Answer:

t = -24*log(2/3)

Step-by-step explanation:

The expression is:

V = 22,500*10^(-t/12)

Replacing with V = 10,000 and isolating t, we get:

10,000 = 22,500*10^(-t/12)

10,000/22,500 = 10^(-t/12)

4/9 = 10^(-t/12)

(2/3)² = 10^(-t/12)

2*log(2/3) = -t/12

-12*2*log(2/3) = t

t = -24*log(2/3)

Answer:

The number of years after purchase at which Vishal's car will be worth $10,000 is [tex]Log_{10}\left (\frac{9}{4} \right )^{12}[/tex]  years

Step-by-step explanation:

The relationship is given as follows

Value, V of the car = 22500×[tex]10^{-t/12}[/tex]

Therefore, when the car is $10,000 we will have

$10,000 = 22,500×[tex]10^{-t/12}[/tex]

Which will give;

[tex]\frac{10000}{22500} =\frac{4}{9} = 10^{-\frac{t}{12}}[/tex]

Hence;

[tex]Log\frac{4}{9} = Log(10^{-\frac{t}{12}} )[/tex]

Therefore;

[tex]-\frac{t}{12}\times Log_{10} 10 = Log\frac{4}{9}[/tex]

[tex]\because Log_{10} 10 = 1, \ we \ have; \ -\frac{t}{12} = Log_{10}\frac{4}{9}[/tex]

Which gives;

[tex]t = -12 \times Log_{10}\frac{4}{9} \ or \ t = Log_{10}\left (\frac{4}{9} \right )^{-12}[/tex]

[tex]\therefore t = Log_{10}\left (\frac{9}{4} \right )^{12}[/tex] years

Evaluated, the above equation becomes t = 4.226 years

Therefore, the number of years after purchase at which Vishal's car will be worth $10,000 = [tex]Log_{10}\left (\frac{9}{4} \right )^{12}[/tex]  years.

Step-by-step explanation:

Answer:

The mean is 15 so adding another 15 keeps the mean unchanged.

Step-by-step explanation:

The value of number is,

⇒ 12 + 35 = 47

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

The expression is,

⇒ A number is 12 more than 35.

Now, Let a number is,

⇒ x

Hence, We can formulate;

⇒ x = 12 + 35

⇒ x = 47

Therefore, The value of number is,

⇒ 12 + 35 = 47

1,050

Step-by-step explanation:

Answer:

1050 feet

Step-by-step explanation:

The submarines location is 800 feet below which is -800 and the drones location is 250 feet above which is just 250. To get to -800 from 250 you subtract 1050 so the total distance is 1050.

Final answer:

An event with exactly 12 possible outcomes may refer to rolling a single 12-sided die, rolling two six-sided dice with one specific number on one die and any number on the other, or flipping a coin and rolling a six-sided die.

Explanation:

The event that has exactly 12 possible outcomes could be the rolling of a 12-sided die once, which would result in one of the twelve numbers coming up. Another example is rolling two six-sided dice and considering the situation where one specific number must come up on one die, while any of the six numbers could come up on the other die, thus also resulting in 12 possible outcomes (6 possible outcomes for the second die, times 1 fixed outcome for the first die), assuming the outcome of interest is only about the second die. Yet another example could be flipping a coin and rolling a six-sided die, where the coin has two possible outcomes (heads or tails) and the die has six possible outcomes, giving us a total of 12 outcomes (2 x 6 = 12).

Answer:

2.25

Step-by-step explanation:

5=15 and d8=170=which of the following is closest to the value of fb

The value of b is closest to (2) 2.25

An exponential function is represented as:

[tex]f(x) = a(b)^x[/tex]

[tex]f(5) = 15[/tex] means that:

[tex]ab^5 = 15[/tex] ---- equation (1)

[tex]f(8) = 170[/tex] means that:

[tex]ab^8 = 170[/tex] ---- equation (2)

Divide equation (2) by equation (1)

[tex]\frac{ab^8}{ab^5}= \frac{170}{15}[/tex]

Divide common factors

[tex]b^3= 11.33[/tex]

Take the cube root of both sides

[tex]b= \sqrt[3]{11.33}[/tex]

Evaluate the expression

[tex]b= 2.246[/tex]

2.246 can be approximated to 2.25

Hence, the value of b is closest to (2) 2.25

Answer:

[tex]37.5^{\circ}\,,\,60^{\circ}\,,\,82.5^{\circ}[/tex]

Step-by-step explanation:

Given: measures of the angles in a triangle are [tex]1.5x,2.4x,3.3x[/tex]

To find: equation to determine the measure of each angle in the triangle and exact measure of each angle in the triangle

Solution:

According to angle sum property, sum of angles of a triangle is [tex]180^{\circ}[/tex]

So, equation to determine the measure of each angle in the triangle is [tex]1.5x+2.4x+3.3x=180^{\circ}[/tex]

[tex]1.5x+2.4x+3.3x=180^{\circ}\\7.2x=180^{\circ}\\x=\frac{180^{\circ}}{7.2}=25^{\circ}[/tex]

So,

[tex]1.5x=1.5(25^{\circ})=37.5^{\circ}\\2.4x=2.4(25^{\circ})=60^{\circ}\\3.3x=3.3(25^{\circ})=82.5^{\circ}[/tex]

Answer:True

Step-by-step explanation: The smaller triangle is half as small

The triangles are similar, so this is true.

The blue triangle has been enlarged by a scale of 2. It's 4 units up and 2 units to the right and the second larger triangle is 8 units up and 4 to the right, so it's 2 times bigger.

Answer:533.33 meters

Step-by-step explanation:

The mile would be four laps around a track which is 400 meters so 400x4 divided by 3 (I ran track that’s the only reason I figured this out)

Answer:

B

Step-by-step explanation:

I think the answer is B as it is on the positive side.

In a relay race with 4 runners covering a total distance of m miles, each runner will cover an equal share of the distance, specifically m ÷ 4 miles.

If there is a relay race with 4 runners and the total distance run is m miles, we want to find the distance each person runs. Since the total distance is divided equally among the 4 runners, we can express the distance each runner will run as:

The distance each runner runs = Total distance ÷ Number of runners

The distance each runner runs = m ÷ 4

This expression shows that each runner will run a quarter of the total distance m.
