one teacher want to give each student 4/5 of a slice of pizza, if the teacher has 4 slices of pizza, then how many students will

GuDViN [60]

Answer:

The answer is 5 students.

Step-by-step explanation:

This problem is a division problem.

To solve, divide 4 by 4/5.

There is a strategy for this- Keep, Change, Flip.

Keep the dividend like it is, which is 4 or 4/1.

Change the division to multiplication.

And flip the divisor- 4/5 to 5/4.

When you multiply, you should get 20/4.

Simplify by dividing 20 by 4.

20 divided by 4 is 5.

So the answer is 5 students

If a polynomial function f(x) has roots 3 and StartRoot 7 EndRoot, what must also be a root of f(x)?

Ivenika [448]

Answer:

–√(7) must also be a root of f(x)

Step-by-step explanation:

Given that the roots of an equation is 3 and √(7). This means that x = 3 or √(7). Therefore, the function is definitely going to be:

f(x) = (x – 3)(x² – 7)

This is because we are dealing with √(7) and what brought about √(7) was x² = 7.

If this is the case, we know that x² = 7 will give

x = ±√(7)

Hence, our roots are x = 3 or √(7) or –√(7). Therefore, –√(7) must also be a root of f(x).

Find a degree 3 polynomial P such that P(−1) = −3, P(0) =−2, P(1) = −1, and P(2) = 6.

Aleksandr-060686 [28]

Answer:

Step-by-step explanation:

let polynomial P(x)=ax³+bx²+cx+d

-3=-a+b-c+d

-2=d

-1=a+b+c+d

-1=a+b+c-2

a+b+c=1

-3=-a+b-c-2

a-b+c=1

a+b+c-(a-b+c)=1-1=0

2b=0

b=0

so a+c=1

6=8a+4b+2c+d

6=8a+4b+2c-2

8a+4b+2c=8

4a+2b+c=4

or 4a+0+c=4

4a+c=4

a+c=1

subtract

3a=3

a=1

1+c=1

c=0

Find the length of the third side. If necessary, round your the nearest tenth.

Ksivusya [100]

Answer:

Step-by-step explanation:

Use Pythagorean theorem,

base² + altitude² = hypotenuse²

7² + altitude² = 25²

altitude² = 25² - 7²

= 625 - 49

= 576

altitude = √576

altitude = 24

Elena has some bottles of water that each holds 17 fluid ounces. A. Write an equation that relates the number of bottles of wate

Fudgin [204]

Answer:

A. y = 17x

B. 867 fluid ounces

C. 3 bottles

Step-by-step explanation:

There are few bottles of water that each contain 17 fluid ounces of water.

A. If the number of bottles is given by x and the total volume of water those bottles contain is y in fluid ounces, then the equation that relates x and y is

y = 17x ...... (1) (Answer)

B. If x =51, then the volume of water in 51 bottles will be given by equation (1) as

y = 51 × 17 = 867 fluid ounces. (Answer)

C. If y = 51 fluid ounces, then from equation (1), the number of bottles will be given by x = 51/17 =3 bottles. (Answer)
