3 There are 5 times as many boys as girls in a school.
Together the school has 810 pupils.
How many boys are there?

Answers

Answer 1

Answer:

Number of boys = 675

Step-by-step explanation:

Given that:

There are 5 times as many boys as girls in a school.

Number of pupils in school = 810

Let,

x be the number of girls

y be the number of boys

According to given statement;

x+y=810      Eqn 1

y = 5x         Eqn 2

Putting y=5x in the Eqn 1

x+5x=810

6x=810

Dividing both sides by 6

[tex]\frac{6x}{6}=\frac{810}{6}\\x=135[/tex]

Putting x=135 in Eqn 2

y = 5(135)

y = 675

Hence,

Number of boys = 675

jester has a piece of wood measuring 1 and 2/3 m.he needs to cut in pieces measuring 3/4 m long.how many pieces of wood did jester cut​

Answers

Answer:

2 pieces

Step-by-step explanation:

Given

[tex]Length = 1\frac{2}{3}m[/tex]

[tex]Pieces = \frac{3}{4}m[/tex]

Required

Calculate the number of pieces

To do this, we have to divide the length of the wood by the length of each piece.

Represent this with x

[tex]x= \frac{Length}{Pieces}[/tex]

[tex]x= 1\frac{2}{3}/\frac{3}{4}[/tex]

Convert mixed numbers to improper fraction

[tex]x= \frac{5}{3}/\frac{3}{4}[/tex]

Change division to multiplication

[tex]x= \frac{5}{3}*\frac{4}{3}[/tex]

[tex]x= \frac{20}{9}[/tex]

[tex]x = 2.22[/tex]

[tex]x = 2[/tex]

Write the equation of the function g(x) if g(x) = f(x - 3) +1 and f(x) = x3 + 1.

Answers

Answer:

Solution,

f(x) = [tex]x^{3}[/tex] + 1

Put x = x - 3,

f(x - 3) =  [tex](x-3)^{3}[/tex] + 1

Now,

g(x) = f(x - 3) + 1

or, g(x) =[ [tex](x-3)^{3}[/tex] +1 ] + 1

or, g(x) = [tex]x^{3} -9x^{2} + 27x - 1 + 1+1[/tex]

or, g(x) = [tex]x^{3} - 9x^{2} +27x + 1[/tex]

Noah was assigned to make 64 cookies for the bake sale. He made 25% MORE than that. How many cookies did Noah make? Explain how you got your answer.



PLEASE HELP MEH! WILL MARK BRAINLIEST!! DUE TODAY

Answers

Answer:

8 cookies were left after the bake sale. 72 were sold.

Step-by-step explanation:

64*1.25= 80

80*.9= 72

8

125% of 64 is equal to 80.

90% of 80 is equal to 72.

The number left was 10% of the number he made. The number he made was 125% of 64, so the number left was 8

 10% × 125% × 64 = 0.125 × 64 = 8

At a trout farm, most of the trout have a length of 23.5 cm. The length of some differ from this by as much as 2.1 cm. Write and solve an absolute-value inequality to find the range of lengths of the trout.

Answers

Answer:

21.4 ≤ x ≤ 25.6

Step-by-step explanation:

The absolute value of a number is the non-negative value of the number without regard to its sign.

The absolute value of a real number x (|x|) is x for x is positive and -x for x is negative.

Let x represent the length of the trout. Since most trout have a length of 23.5 cm and differ by 2.1 cm, then x can be represented by:

|x - 23.5| ≤ 2.1

x - 23.5 ≤ 2.1 or -(x - 23.5) ≤ 2.1

x ≤ 2.1 + 23.5 or x - 23.5 ≥ -2.1

x ≤ 25.6 or x ≥ 21.4

Hence, the range of lengths of the trout is 21.4 ≤ x ≤ 25.6
