It did!

Thanks

${\sqrt{72} \over \sqrt{25}}$=${ \sqrt{3^2*2^2*2} \over 5}$=

${6\sqrt{2} \over 5}$

Your question is not complete

the formula for finding the area of a trapezoid is A = (1/2)(h)(b1 +b2)

with b1 = 6 and b2 = 16

can you figure out the rest?

$(\frac{-1}{3})(-4-3x)=\frac{1}{2}$

       -5

$x=$  -

        6

I tend to make mistakes on these kind of problems, so can someone check my answer?

thank you

(1, 676)=> 1+1+676+676 = 1354

(2, 338)=> 2+2+338+338 = 680

(4, 169)=> 4+4+169+169 = 177

(13, 52)=> 13+13+52+52 = 130

(26, 26)=> 26+26+26+26 =104

On February 21, a 61-year-old man who had gone to work in Italy disembarked in Brazil, more specifically in the city of São Paulo. After presenting the symptoms of the new coronavirus (fever, sore throat, runny nose and cough), he went to the hospital, where the first case of the disease in the country was confirmed through tests. From then on, we quickly had an explosion in the number of cases due to the exponential growth in the number of infected. Making a mathematical approximation through the disease progress function we were able to arrive at the following function representing the number of cases by the time in days of the first case. f(x) = Xi * R^t where : f(x) is the number of cases in a given time t Xi is the initial number of cases in a population R or Rt is the rate of spread, that is, to how many people an infected person transmits the disease on average t - Time measured in days. Calculate: If, when we reach 1,000,000 cases, our Rt rate drops to 0.90 ( Rt = 0.90 ) , how long would it take to zero the number of daily cases. (f(x) = 0 and Xi = 1,000,000 ).

uh here's the translation

i honestly don't know how i would do this one

it's way too wordy and it's confusing me.

Thanks CPhill

1. $a+b+c=-3$

2. $a+3b+c=9$

3. $a+b+3c=-19$

Subsrtacting equation number 1 from equation number 2 we get

$b=6$

Substracting equation number 1 from equation number 3 we get

$c=-8$

Then putting $b$ and $c$ into equation 1

we get

$a=-1$

so

$abc=-1\times-8\times6=$48

I'm not CPhil but i'll try my best at this.

We have these inequalities

2x + 3y ≤  40

y - 2x ≤ 6

so we get 11.5

here's a diagram ==>

there are 3*4! arrangements but since there are two 8s and two 0s, we have to divide by 2!*2!

so

$\frac{3*4!}{2!*2!}=$

18

How many pages did Ben read?

Ben read 18 pages

How many fewer pages did Amy compose than Ben?

18 - 12 = 6

How many pages did Amy and Ben read in all?

18 + 12 = 30

I'm obviously not CPhill but

if it takes Jana 24 minutes to walk 1 mile

then it takes her 1 minute to walk 1/24 miles

so in 10 minutes she'll walk

$\frac{1}{24}\times10$ = $\frac{10}{24}$

as a decimal and rounded to the nearest tenth 

the answer is 0.4

im too lazy to write it all down but we eliminate January, April, June, August, September, October, and December since they arent prime.

2020 was a leap year so we count February 29

if we add all the dates together, we get 53
