Answer:

12.955

Step-by-step explanation:

you know they made errors because between all the numbers, the whole number is 12 and the rest are 0, which means that the whole number part cannot be less than 12. While for the decimal part the largest number of decimal places is 3, and that what your final answer has to have. I hope this helped :)

Answer:

3

Step-by-step explanation:

Leading Coefficients are numbers in front of the variable (x in this case) with the largest exponent (2 in this case)

3x^2 where 3 is the number in front of the variable.

Given that the area is 81 square inches, find out the length of the side of a square.

Area of Square = s^2

To find out the length, find the square root of 81.

Square root of 81 is 9.

9 x 9 = 81

Therefore, the length of a side on a square with an area of 81 inches is 9 inches.

Step-by-step explanation:

1. 6 x 4 x 3= 72

2. 5 x 3 x 4= 60

3. 5 x 2 x 2= 20

5 x 3 x 1= 15

20 + 15= 35

4. 5 x 3= 15

Answer:

4

Step-by-step explanation:

The area of a triangle is

A=1/2 bh

Where b is the base and h is  the height

A = 1/2 (4)(2)

A = 4

In triangle ABC and triangle ADE

angle A = angle A (common)

angle ABC = angle ADE

By AA similarity criterion , they are similar

Thus

AB/AD = BC/DE

4/12 = x/12

Thus x = 4

Answer:

The arc length of a sector:

[tex]A = \frac{9}{10} \pi[/tex]

Step-by-step explanation:

-The equation for finding the Arc length, would be:

[tex]Arc length = \frac{a}{360\textdegree} 2\pi r[/tex]

-Use the given radius and the central angle for the equation:

[tex]A = \frac{18\textdegree}{360\textdegree} 2\pi (9)[/tex]

-Then, solve the equation:

[tex]A = \frac{18\textdegree}{360\textdegree} \times 2\pi \times 9[/tex]

[tex]A = \frac{1}{20} \times 2\pi \times 9[/tex]

[tex]A = \frac{2}{20}\pi \times 9[/tex]

[tex]A = \frac{1}{10}\pi \times 9[/tex]

[tex]A = \frac{9}{10}\pi[/tex]

So, the arc length of a sector is [tex]\frac{9}{10} \pi[/tex] .

Answer:

E

Step-by-step explanation:

If you add 22 onto the sum of all the points and divide by the amount of games (6), you get 12.

The score she must get during the 6th game to have a mean of 12 point score per game is 22.

The mean is the average of numbers.

Mathematically, it is represented as follows;

mean = sum of terms / number of terms

Therefore, to get a mean of 12 point score per game the 6th score can be calculated as follows:

let

x = 6th score

Hence,

8 + 12 + 10 + 6 + 14 + x   / 6 = 12

50 + x / 6 = 12

cross multiply

12 × 6 = 50 + x

72 = 50 + x

72 - 50 = x

x = 22

Therefore, the score is 22.

Answer:

Step-by-step explanation:

Given

Diver is standing [tex]7\ m[/tex] above water

Diver is at a maximum height of [tex]h=7+2=9\ m[/tex] at [tex]t=2\ s[/tex]

So, at [tex]t=2\ s[/tex] his velocity is zero

After this he will be under free fall

using

[tex]s=ut+\frac{1}{2}at^2[/tex]

here [tex]u=0[/tex]

[tex]s=\frac{1}{2}\times 10\times (3)^2[/tex]

[tex]s=5\times 9=45\ m\quad \text{(not possible)}[/tex]

but the distance between the pool and Henry is [tex]9\ m[/tex]

So, he reaches the pool before [tex]5\ s[/tex]

[tex]9=\frac{1}{2}\times 10\times (t)^2[/tex]

[tex]t=\sqrt{1.8}[/tex]

[tex]t=1.34\ s[/tex]

So, he reaches pool at [tex]t=2+1.34=3.34\ s[/tex] after diving off the board

Answer:

Ignore the answer above, the correct answer is 4.5m.

Step-by-step explanation:

If you ignore all the useless information, you'll see that the parabola Henry creates has a vertex of (2,9) (because obviously the parabola opens downwards). Using this, we can deduce the vertex form of the equation for this parabola to be y=-a(x-2)²+9. This is because the vertex is always equal to (h,k), and the vertex form of any parabola is written as y=a(x-h)²+k. Now, you can solve for a to find it is 0.5, by using (0,7) as the y-intercept (aka the diving board, his starting location). Now, you can graph y=-0.5(x-2)²+9 by using mapping notation, (I find to be the easiest), or any other strategy you'd like. Once graphed, it is clear to see that when the parabola reaches 5 along the x-axis, (simpler if you think of the x-axis as time and the y-axis as height), it is plotted at 4.5 on the y-axis. This means that after 5 seconds, Henry is 4.5 meters above the water.

We have been given that Toru has $80 to pay for dog grooming. The fee is $72 plus 7.25% tax. We are asked to determine whether Toru has enough money for grooming or not.

The total charges for grooming would be $72 plus 7.25% of $72.

[tex]\text{Total charges for grooming}=\$72+\$72\times \frac{7.25}{100}[/tex]

[tex]\text{Total charges for grooming}=\$72+\$72\times0.0725[/tex]

[tex]\text{Total charges for grooming}=\$72+\$5.22[/tex]

[tex]\text{Total charges for grooming}=\$77.22[/tex]

Since total cost of grooming is $77.22 and Toru has $80 to pay for grooming, therefore, Toru has enough money for grooming.

The question is not complete because it is not written correctly

Complete Question:

The drama club is holding auditions for five different parts in a one act play. If 9 people audition, how many ways can the roles be assigned?

a. 362,880

b. 15,120

c. 126

d. 120

Answer:

b. 15,120

Step-by-step explanation:

In other to solve the question above, we would use the formula for permutation.

This is because when assigning 5 DIFFERENT roles to 9 people, the order of assigning the roles is important. The formula for permutation, is used when order is involved.

Permutation (n, r) = nPr = n!/(n - r)!

In the above question,

n = 9 people

r = 5 different parts

9P5 = 9!/(9 - 5)!

= 9!/4! = 9×8×7×6×5×4×3×2×1/ 4×3×2×1

= 362880/ 24

= 15,120

Therefore, the number of ways that the roles can be assigned is 15,120 ways

Answer:

exponential decay

Step-by-step explanation:

exponential decay describes the process of reducing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula y=a(1-b)x wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.Exponential decay occurs when the amount of decrease is directly proportional to how much exists.

Step-by-step explanation:

Answer:

D: (18,0)

I got it right on Edge 2020

An equation is formed of two equal expressions. The correct option is D.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the two systems of equations,

y = -(1/3)x + 6

y = (1/3)x - 6

Substitute the value of y from equation one with two, we will get,

-(1/3)x + 6 = (1/3)x - 6

6 + 6 = (1/3)x + (1/3)x

12 = (2/3)x

x = (12×3)/2

x = 18

Substitute the value of x in any one of the equations,

y = (1/3)x - 6

y = (1/3)(18) - 6

y = 0

Hence, the solution of the system of equation is (18, 0).

#SPJ2

Answer:

Step-by-step explanation:

Let x represent the distance between Earth and its moons.

Saturn’s rings span up to about (7.5 × 10^-1) of the distance between the Earth and its moons. It means that Saturn’s rings span is

(7.5 × 10^-1)x

If Saturn’s rings span up to 2.82 × 10^5 kilometers, it means that

(7.5 × 10^-1)x = 2.82 × 10^5

Dividing both sides of the equation by 7.5 · 10^-1, it becomes

x = (2.82 × 10^5)/(7.5 × 10^-1)

x = 3.76 · 10^5 km

Nina:

Nina earned $177.60 for 14 hours,hence hourly rate is $ 12.69   ($177.60/14)

Ty:

Ty earned $148.50 for 18 hours period of work,thus earned $8.25  ($148.50/18)

Kim earned $137.60 for 16 hours duration of work,invariably Kim earned  $8.60 ($137.60/16)
