Abcd, 4a = d, b=6a, c = b+3...b can only be 6, which means a can only be 1, which means d can only be 4 and c then must be 9
So 1694 is the number.

kramer

Answer:

Tammy

Step-by-step explanation:

Tammy read 7.75 hours last month. Kelley read 7.69 hours

Jim read 7.075 hours.

We would arrange the hours of reading from smallest to the highest

7.075, 7.69, 7.75

The person who spent the most time reading is the person with the highest number of hours that was spent reading. This person is Tammy.

Therefore, person who spent the most time reading is Tammy because she read for 7.75 hours.

The slope f′(x) at each point (x,y) on a curve y=f(x) is given, along with a point (a,b) on the curve. Use this information to f

Montano1993 [528]

$f'(x)=\dfrac{4x}{1+7x^2}$

Integrating gives

$f(x)=\displaystyle\int\frac{4x}{1+7x^2}\,\mathrm dx$

To compute the integral, substitute $u=1+7x^2$ , so that $\frac27\,\mathrm du=4x\,\mathrm dx$ . Then

$f(x)=\displaystyle\frac27\int\frac{\mathrm du}u=\frac27\ln|u|+C$

Since $u=1+7x^2>0$ for all $x$ , we can drop the absolute value, so we end up with

$f(x)=\dfrac27\ln(1+7x^2)+C$

Given that $f(0)=10$ , we have

$10=\dfrac27\ln1+C\implies C=10$

so that

$\boxed{f(x)=\dfrac27\ln(1+7x^2)+10}$

X + (4x+15) = 180
5x+15=180
5x=165
x=33
4(33)+15=147. (Or you could subtract 33 from 180)
Check answer: 33+147=180 yes

A mother had a girl named Mia when she was 18. Four years later, when she was twenty two, she had triplets. Then a year later, a

dexar [7]

She was 22 when she had triplets
so if the triplets are 12 then just add
22+12=34
or when she had Mia she was 18
if Mia is 16 then add
18+16=34
Also, she had another child at 23
if the child is 11 then add
23+11=34
Hope it helps! :)
