Answer:

The sum is equal to -905,200

Step-by-step explanation:

we know that

The formula to calculate the sum is equal to

Sn=n\frac{(a1+an)}{2}

In this problem

n=775 -----> number of terms

a1 is the first term

a1=(-3(1)-4)=-7

an is the last term

an=(-3(775)-4)=-2,329

substitute

Sn=775\frac{(-7-2,329)}{2}=-905,200

TWENTY NINE POINTS AND BRAINLIEST IF YOU CAN ANSWER THIS!!! The number of milligrams of medication in Noelle’s body is about wha
kolbaska11 [484]

Lets do the working for the amount of medication remaining in Noelle's body.


Day 1:


600 × 0.6 = 360


Day 3:


360 × 0.6 = 216


Day 4:


216 × 0.6 = 129.6


Day 5:


129.6 × 0.6 = 77.76


By the time Karey is taking the medication, Noelle only has 77.76 in her body.


This expressed as a percentage in relation to Karey's amount is :


77.76/600 × 100 = 12.96%


= 12.9%

Jorge’s monthly bill from his Internet service provider was $25. The service provider charges a base rate of $15 per month plus
Hatshy [7]

Answer:

Jorge was charged for 10 hours that month

Step-by-step explanation:

  Given : Jorge’s monthly bill from his Internet service provider was $25.

Also given :  The service provider charges a base rate of $15 per month plus $1 for each hour that the service is used

We have to find the number of hours that Jorge was charged for that month.

Let the number of hour be x,

Total bill =  base rate + 1 (number of hours used)

Total bill =  base rate + 1(x)

Substitute the values, we get,

⇒ 25 = 15 + 1 (x)

Solving we get,

⇒ 25 - 15 = x

10 = x

Thus, Jorge was charged for 10 hours that month

I believe the fastest way to solve this problem is to take any two of the given points and to find the slope and y-intercept of the line connecting those two points.  

Let's choose the 2 given points (-3,16) and (-1,12).
Going from the first point to the second, the increase in x is 2 and the increase in y is actually a decrease:  -4.  Thus, the slope of the line connecting these two points is m = -4/2, or m = -2.

Now use the slope-intercept formula to find the y-intercept, b.

One point on the line is (-3,16), and the slope is m = -2.

Thus, the slope-intercept formula y = mx + b becomes 16 = -2(-3) + b.
Here, b comes out to 10.

So now we have the slope and the y-intercept.  Write the equation:

y = mx + b becomes y=-2x+10.  Which of the four given answer choices is the correct one?

A kangaroo hopped 1/3 of the distance to the lake with her baby in her pouch. She hopped the remaining 7040 yards without her ba
Norma-Jean [14]

Step-by-step explanation:

she hopped 10560 MI to the lake because the remaining miles was the 7040 miles without her baby and if you do 7040 (the 2/3s) divided by 2 you would get 3520 which is the 1/3 of the distance to the lake so 7040 miles + 3520 miles equals 10560 miles hopped to the lake. Hope this helped ^_^
