William is 5 times as old as umaima and is also 8 year older hen umaima. how old is william?

1 answer:

6 0

Let S represent William, and M represent Umaima.
S = 5M
S = M + 8
Since they are both values of S, they equal each other.
5M = M + 8
Subtract M from each side
4M = 8
Divide each side by 4
M = 4\2
Umaima is 2; therefore William is 10.

A retailer who sells backpacks estimates that by selling them for x dollars each, she will be able to sell 100−x backpacks each

zvonat [6]

Answer:

x = 50

R = $2500

Step-by-step explanation:

Given in the question a quadratic equation,

−x² + 100x

To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x

The value of -b/2a tells you the value x of the vertex of the function

−x² + 100x

here a = -1

b = 100

Selling price = -(100)/2(-1)

= 50

R = −(50)² + 100(50)

= 2500

Two separate bacteria populations grow each month and are represented by the

ASHA 777 [7]

Answer:

Option 4.) month 4

Step-by-step explanation:

we have

$f(x)=3^{x}$ ----> equation A

$g(x)=7x+6$ ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (3,27)

That means -----> For x=3 months, the populations in both functions are the same (the bacteria populations is 27)

therefore

For x> 3 months the f(x) population is greater then the g(x) population

F(x) = 3x² + 9x – 16<br> Find f(-8)

Nezavi [6.7K]

Answer: 104

Step-by-step explanation:

$f(-8)$ represents $f(x)$ evaluated at $x=-8$ .

$f(-8)=3(-8)^2 +9(-8)-16\\\\=192-72-16\\\\=120-16\\\\=104$

For the equation -2(x+1) = 8, Caitlin distributes the 2 to get, -2x +2 = 8. Then she subtracts the 2 from both sides to get -2x

mamaluj [8]

Answer:

No.

Step-by-step explanation:

She wronged in Step 2, -2x + 2 = 8 .

The correct way is :

-2(x+1) = 8

-2x <u>–</u> 2 = 8

A bowl has the shape of a hemisphere whose diameter is 14 centimeters. If this bowl is filled with water, how many cubic centime

ASHA 777 [7]

Answer:

The cubic centimeters of water it will take to fill the bowl is 718.67 cm³

Step-by-step explanation:

Given;

diameter of the hemisphere, d = 14 cm

radius of the hemisphere, r = d/2 = 14/2 = 7 cm

The volume of the hemisphere is calculated as;

$V = \frac{2}{3} \pi r^3\\\\V = \frac{2}{3} \times \frac{22}{7} \times (7 \ cm)^3\\\\V = 718.67 \ cm^3$

The cubic centimeters of water it will take to fill the bowl is 718.67 cm³
