Write a polynomial function of least degree with integral coefficients that has the given zeros. ​

Answers

Answer:

Step-by-step explanation:

To get the equation, you must create the factors containing the roots.

So for example the first set of roots can be produced from

(x -2)(x^2 + 9)

which equals (when expanded) x^3 + 9x - 2x^2 - 18 which when put in the correct order gives

x^3 -2x^2 + 9x - 18

The second one is a bit more difficult to judge.

Ray is x years old. His brother Ron is y years older than Ray.
What will the difference of their ages be in 5 years?

Answers

ray is x years old

Ron is x+y years old

in 5 years ron will be 5 years older than now, so x+y+5 years old

 orAnswer:

x - x + y + 5 - 5 = y  or   x + y - x = y

Step-by-step explanation:

The difference now,

x + y - x = y

The difference in 5 years,

(x + y + 5) - (x + 5) = x - x + y + 5 - 5

x - x + y + 5 - 5 = y

The difference in their ages never changes

Ben and Carson went to the movies with friends. Ben purchased 3 popcorn and 2 boxes of candy for $41. Carson purchased 1 popcorn and 2 boxes of candy for $29. How much did the popcorn cost?

Answers

Answer:

$6

Step-by-step explanation:

B- 3P+2C=$41

C-1P+2C=$29

since they both bought at least 1 popcorn and 2 candy you can just subtract 29 from 41. you get 12 which equals the other 2 popcorns that ben bought

12/2=6

since you need to find the price of 1 popcorn you have to divide 12 by 2

Lauren's scores on her math tests were 96, 95, 98, 92, 94, 93, and 97. What score could Lauren get on her next math test so that the mean and median remain the same? Complete the explanation. The score on her next test that would keep her mean and median the same would be Because her mean and median are already another score of this value would not alter the mean or the median.​

Answers

Answer:

Lauren needs to get 95  on her next math test so that the mean and median remain the same

Step-by-step explanation:

92+93+ 94+ 95+96+97+98  = 665

665/2 =95

mean=95

median=95

x=  score could Lauren get on her next math

(665+ x)/8 =95

multiply both sides by 8 to eliminate fraction

665 +x = 760

x=95

So now the median is the same

(95+95)/2=95

      shorcut:

with 7 scores 95 is the median(in the middle)

with 8 scores ,we need a number that added to 95 and divided by 2 is still 95  That number is 95

For each pair figures, find the ratio of the area of the first figure to the area of the second. 14mm 7mm

Answers

The ratio of the area of the first figure to the area of the second figure is 4:1

Ratio of the areas of similar figures

From the question, we are to determine the ratio of the area of the first figure to the area of the second figure

The two figures are similar

From one of the theorems for similar polygons, we have that

If the scale factor of the sides of two similar polygons is m/n then the ratio of the areas is (m/n)²

Let the base length of the first figure be ,m = 14 mm

and the base length of the second figure be, n = 7 mm

∴ The ratio of their areas will be

[tex](\frac{14 \ mm}{7 \ mm})^{2}[/tex]

[tex]= \frac{196 \ mm^{2} }{49\ mm^{2} }[/tex]

[tex]=\frac{4}{1}[/tex]

= 4:1

Hence, the ratio of the area of the first figure to the area of the second figure is 4:1

there are 36 pupils in a class.the number of boys is twice the number of girls.how many are girls?
​

Answers

Answer:

12 girls

Step-by-step explanation:

Boys to girls ratio= 1:2

Thats means there are (1+2) 3 total parts.

So [tex]\frac{36}{3}[/tex]=12

Each part is 12 so

boys is 12*2= 24 boys

Girls id 12*1= 12 girls

Answer:

12

Step-by-step explanation:

Total number of students in class ⇒ 36

Given that,

The number of boys is twice the number of girls.

First, let us make an expression to find the number of girls.

For that, let the number of girls be x.

Number of girls ⇒ x

Number of boys ⇒ 2x

Total number of pupils ⇒ x + 2x

So,

x + 2x  = 36

3x = 36

Divide both sides by 3.

x = 12

Therefore, there are 12 girls and 24 boys in the class.

Find the area of a green shaded region in the figur

Answers

Answer:

Step-by-step explanation:

Solution:

The shape given is a trapezium.

The area of the green region = Area of the outer trapezium - Area of the inner trapezium.

[tex]Area\: of\:a\:trapezium\:=\frac{1}{2}\:(a+b)h[/tex]

Allison is making fruit drinks for her friends.
Each fruit drink is made with 3/5 cup of
strawberries and 1/5 cup of blueberries. If
Allison is making fruit drinks for 6 friends,
how many cups of fruit will she need??

Answers

The number of cups of fruit Allison will need is = 4 ⅘ cups of fruits

Calculation of total quantity of fruits

The quantity of strawberries needed for each fruit drink= 3/5 cup

The quantity of blueberries needed for each fruit drink = 1/5 cup

Therefore the total quantity of fruits needed for each drink = 3/5 + 1/5

= 4/5

If 4/5 = 1 fruit drink

X = 6 fruit drinks

Make X the subject of formula,

X = 4/5 × 6

X = 24/5

X= 4 ⅘

Therefore, the number of cups of fruit Allison will need is = 4 ⅘ cups of fruits
