1- the answer is 120

$360 - (180 + 60) = 360 - 240 \\ = 120$

2- the answer is 74

$360 - (135 + 77) = 360 - 212 \\ = 148 \\ \\ 148 \div 2 = 74$

3- it's 84
$42 \times 2 = 84$

good luck

Help with this exponential function!

The population size after 6 years and after 8 years are 147 and 169 population respectively

<h3>Exponential functions</h3>

The standard exponential function is expressed as y = ab^x

where

a is the base

x is the exponent

Given the function that represents the population size P (t) of the species as shown;

$p(t)=\frac{550}{1+5e^{-0.1t}} \\$

For the population size after 6 years

$p(t)=\frac{550}{1+5e^{-0.1(6)}} \\P(6)=\frac{550}{3.744}\\ P(6)=147 population$

For the population after 8 years

$p(t)=\frac{550}{1+5e^{-0.1(8)}} \\P(8)=\frac{550}{3.2466}\\ P(8)=169 population$

Hence the population size after 6 years and after 8 years are 147 and 169 population respectively

At a school pep rally the ratio of students who wore red to those who wore yellow is 7 to 3 their are 300 students at the rally

Serhud [2]

Red to yellow.......7:3....added = 10
so 7/10 of the total students wore red and 3/10 of the total students wore yellow

and there are 300 total students...
7/10(300) = 2100/10 = 210 wore red
3/10(300) = 900/10 = 90 wore yellow

how many more wore red.....(210 - 90) = 120 more students wore red then yellow

What number must you multiply both sides of 3/4a=24 by to get equivalent equation a=32??

Mamont248 [21]

4 because 4 times 24 equals 96 then 96 divided by 3 equals 32
