Step-by-step explanation:

● 3

● 3^2

● 9

● 9 + c

======================================================

Explanation:

3 to the 2nd power is the same as writing 3^2 in shorthand

3^2 = 3 squared

When we square a number, we're multiplying it by itself (having 2 copies total of the number). Think of a square with side length 3 units. Its area is 3^2 = 3*3 = 9 square units.

From here, we add on c to get our answer 9+c. We don't know the value of c, so we cannot evaluate further. Also, 9 and c are not like terms so we cannot combine them.

Answer:

Step-by-step explanation:

From the problem statement the cost price per box is

$250.

And the box contains 4 specific powers, since Zeus plans to make $900 per box  which contains 4 powers

we need to find the selling price

profit= selling price-cost price

let the selling price be x

900=x- 250

x=900+250

x= 1150

Selling price = $1150

Hence the unit cost of a specific power in a box that will see a profit of $900 per box is 1150/4= $287.50

Answer:

Point T is (-1,1)

Step-by-step explanation:

Concept:

If there two points (x1,y1) and (x2,y2) which lies on coordinate plane and them it divided by point p in the ratio m:n then coordinate of point p is given by

p (nx1+mx2)/(m+n),   (ny1+my2)/(m+n)

__________________________________________

Given

points M(-2,-4) and N(1, 5)

ratio : 1:2

point t  is  (2*-2+1*1)/(1+2),   (2*-4+1*5)/(1+2)

=>  (-4+1)/(3),   (-8+5)/(3)

=> -3/3 , 3/3

=> -1, -1

Thus, point T is (-1,1)

Answer:

x = -8

Step-by-step explanation:

To answer this equation solve for x. When doing so make sure to get x one side

First subtract 4x from each side. This means the equation is now

x + 6 = -2

Next subtract 6 on both side and you should find x

x = -8

Answer:

220 ways

Step-by-step explanation:

Total number of flavors (n) = 12

Number of flavors to combine (r) = 3

Recall:

nCr = n! ÷(n-r)! r!

nCr = 12! ÷ (12 - 3)!3!

nCr = 12! ÷ 9!3!

nCr = (12 * 11 * 10) / (3 * 2 * 1)

nCr = 1320 / 6

= 220 ways

Answer:

Total amount Ari would have saved after 6 months is $220

Step-by-step explanation:

Ari received $100 as a birthday gift and has decided to save this money as well as add $20 of his own money each month. The total money Ari has saved can be estimated using the equation y = 20x + 100, where x is the number of months and y is the total amount of money saved. How much money will Ari have saved after 6 months?

Solution

Given:

g(x) = 20x + 100

where,

x = number of months

g(x) = the total amount of money saved

How much money will Ari have saved after 6 months?

g(x) = 20x + 100

When x = 6

g(x) = 20(6) + 100

= 120 + 100

= 220

g(x) = $220

Total amount Ari would have saved after 6 months is $220

Answer:

243 cm^3

Step-by-step explanation:

The faces of a cube are squares.

A = s^2

s^2 = 9 cm^2

s = 3 cm

The side of the square is the edge of the cube and is 3 cm.

V = s^3

V = (3 cm)^3 = (3 cm)(3 cm)(3 cm) = 27 cm^3

The volume of one cube is 27 cm^3.

The volume of 9 cubes is 9 * 27 cm^3 = 243 cm^3

Answer: 243 cm^3

Your question has been heard loud and clear.

a)

Initial velocity , U=50km/h = 250/18 m/s

Final velocity , V = 0 (this is because the car finally comes to rest)

From 3rd equation of motion , V^2-U^2=2AS.

Now , for a car that goes 50km/h , it has been proven that miniumum brake distance is 6 metres.

so , S = 6 metres.

Using this , we can find the distance stopped by car , and then we can find time.

0-(250/18)^2=2*A*6

0= 2*A*6+(250/18)^2

0 = -12A + 192.90 ( minus sign because car is deccelerating)

So , A = 16.07 m/s^2

V^2-U^2 = 2AS

0 - 192.90 = 2* 16.07*S

So , S (distance) = 24 metres.

Now , we know time = distance / speed

so , time = 24 / 253 = 0.094 seconds

Thank you

Y=-1

Step-by-step explanation:

Y-4-4Y=-1

-3Y=-1+4

-3Y=3

Y=3÷-3

Y=-1

Answer:

y = -1

Step-by-step explanation:

y - 4 - 4y = - 1   Combine like terms

y - 4y - 4 = - 1

-3y - 4 = - 1 Add 4 to each side

-3y - 4 + 4 = -1 + 4

-3y = 3 Divide each side by -3

-3y/-3 = 3/-3

y = -1

Answer: x=-4

Step-by-step explanation:

Answer:

The correct answer is x = -4.

Step-by-step explanation:

To solve this problem, we should first use the distributive property to get rid of the parentheses on the left side of the equation.  This is modeled below:

4(2x - 3) = 11x

8x - 12 = 11x

Then, we should subtract 8x from both sides to move all of the variable terms to the right side of the equation.

-12 = 3x

Finally, we can divide both sides by 3 to get the variable x completely alone on the right side of the equation.

-4 = x

Therefore, the answer to your question is x = -4.

Answer: 0.819

Step-by-step explanation:

Given: X is a normally distributed random variable with mean 95 and standard deviation 3.

Then,  the probability that X is between 89 and 98 will be:

[tex]P(89<X<95)=P(\dfrac{89-95}{3}<\dfrac{X-mean}{standard\ deviation}<\dfrac{98-95}{3})\\\\=P(-2<Z<1)\ \ \ [Z=\dfrac{X-mean}{standard\ deviation}]\\\\ =P(Z<1)-(1-P(Z<2))\\\\= 0.8413- (1-0.9772)\ \ \ [\text{By p-value table}]\\\\= 0.8185\approx0.819[/tex]

Step-by-step explanation:

We would solve this question by cross multiplication.

If a sound of fertilizer covers 45 square feet of lawn and the lawn is 8666.7 square feet

To get fertilizer quantity we have

1 pound = 45 square

Unknown = 8666.7 square feet

8666.7/45

= 192.59 when approximated we get 193.

Therefore she has to buy 193 pounds of fertilizer
