Answer:

104

Step-by-step explanation:

The ratio of boys : girls = 3 : 1 = 3x : x ( x is a multiplier )

There are 52 more boys than girls , so

3x = x + 52 ( subtract x from both sides )

2x = 52 ( divide both sides by 2 )

x = 26, then

3x = 3 × 26 = 78 ← number of boys

Total number = 78 + 26 = 104

PLEASE DO NUMBER 1 SHOW WORK TOO PLEASE
kirill [66]

Answer:

A) False - not a right angle

B) True - it is a right angle

C) True - it is a right angle

D) False-not a right angle

Step-by-step explanation:

A) a*a+b*b=c*c (Asquared+Bsquared=C squared)

    2*2+ 3*3 = 4*4

   4+9=16

    13 does not equal 16

B) 5*5+12*12=13+13

  25+144=169

  169=169 - True

C) 3*3+4*4=5*5

    9+16=25

     25=25 (True)

D) 4+ Root of 3 = Root of 19

    False - square root of a prime number is irrational

The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp. Jackie wants to manipulate the
Sauron [17]

The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp.

calculates three times a year, not just once a year.

f(x)= 4(4)^x

3 times a year

so x becomes 3x

f(x)= 4(1+r)^{3x}

4(4)^x=4(1+r)^{3x}

Take log on both sides

log(4)^x=log(1+r)^{3x}

log(4)^x=log(1+r)^{3x}

Use log property and move exponent before log

xlog(4)=3xlog(1+r)}

Divide both sides by x

log 4 = 3 log(1+r)

Solve for '1+r'

log 4 = log(1+r)^3

Remove log from both sides

4 = (1+r)^3

take cube root on both sides

1.584740= 1+r

1+r = 1.59

f(x)= 4(1+r)^{3x}

so equation becomes

f(x)= 4(1.59)^{3x}

1+r = 1.59

subtract 1 from both sides

So r= 59 = 59%

So growth factor is 59%

Answer is option C
