Answer:

x^2 -4x -21

Step-by-step explanation:

Here, we want to write a quadratic polynomial

We have the sum as -4

Let us have x as the variable

so the sum of the variables is -4x

while the product is -21 x^2

Two factors of 21 that can work here is -7x and 3x

So we have

x^2 - 7x + 3x -21

= x^2 -4x -21

Q12: At Burns High School, 35 of the students are females. ​ ​Of the female students, 13 of them play volleyball. ​ ​What fracti
slega [8]

Step-by-step explanation:

\frac{13}{35}  =  \frac{}{100}

we don't know the numerator. so we should find the scale factor.

to find scale factor divide the 100 by 35

we get the scale factor as 2.86

now multiply the previous fraction by this scale factor

\frac{13}{35}  \times  \frac{2.86}{2.86}  =  \frac{37.18}{100}

13 out of 35 girls play the volleyball in burns high school or we can put it as 37.18 % of the girls at Burns Highschool

A cone-shaped container has a height of 9 inches and diameter of 2.5 inches. It is filled with a
guapka [62]

Answer:

the total value of the liquid in the container is $29.4

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cone

The volume of a cone is expressed as

V=1/3(πr²h)

Given data

Height h= 9 inches

Radius r= diameter/2= 2.5/2= 1.25in

Substituting we have

V= 1/3(3.14)*(1.25)²*9

V= 1/3*(3.14)*14.06

V= 44.156/3

V= 14.7in³

The volume of the cone is 14.7in³

Hence If 1 in³ of liquid costs $2

14.7in³ will cost $x

x= 14.7*2

x= $29.4
