Answer 1

Answer: Neither, they both have the same amount of battery.

Explanation: Stella is 4/6 charged. Stanley is 2/3 charged. When 4/6 is reduced, the equivalent fraction is 2/3.

Answer 2

Answer:

Answer:

the battery is equivalent, if that is not a choice I would go with stanly

Chris brought 2 umbrellas each costing $13.He brought 3 ponchos each costing $4 how much did Jack spend in all

Answers

We know that 2 umbrellas each cost $13, so 13*2=26 and we also know that he brought 3 ponchos that cost $4, so 4*3=12. The question asks how much did Jack spend in all. In all means add, so we add 26+12 which equals 38. So, Jack spent $38.

Jack would have spent a total of 38 dollars all together

The daily high temperature of Elk Creek drops by 1.2°C every day. What is the net change in the daily high temperature after two calendar weeks?

Answers

Answer:

16.8°C

Step-by-step explanation:

Given :The daily high temperature of Elk Creek drops by 1.2°C every day.

To Find:What is the net change in the daily high temperature after two calendar weeks?

Solution:

Since we are given that The daily high temperature of Elk Creek drops by 1.2°C every day.

1 week = 7 days.

So, 2 weeks = $7 * 2 = 14$ days

Temperature drops per day = 1.2°C

So, temperature drops in 14 days = $1.2* 14 =16.8^(\circ)C$

Hence the net change in the daily high temperature after two calendar weeks is 16.8°C.

Answer:

16.8

Step-by-step explanation:

A box contain 170 pens. 6 children each take 4 pens Hiw many pens are left in the box

Answers

6 children each take 4 pens
6 times 4=24
24 taken
170-taken=170-24=146
146 left

So you go 6 times 4 (24) you subtract that from 170.

Solve Systems by Substitution
x+y=-1
3x-2y=2
and
x=y-2
3x-4y=-13

Answers

Problem one:
1.) Isolate one variable of one equation
x+y-x=-1-x
y=-1-x
2.) Plug in equation for isolated value into other original equation
3x-2(-1-x)=2
3.) Distribute
3x+2+2x=2
4.) Add like terms
5x+2=2
5.) Subtract two from both side
5x=0
6.) Divide both sides by 5
x=0
7.) Plug in numerical value for x into one equation (original or not)
0+y=1
8.) Subtract zero from both sides
y=1
For the first problem, the answer is: x=0, y = 1

For the second problem, follow very similar steps:
3(y-2)-4y=-13
3y-6-4y=-13
-y-6=-13
-y=-7
y=7

x=y-2
x=7-2
x=5
That's your answer for the second problem: x=5, y=7

Hope this helps!

1x + 1y = -1 ⇒ 3x - 3y = -3

   3x - 2(5) = 2

To find the area of the shaded region, we can find the area of the rectangle, and subtract the area of the circle (the non shaded part of the rectangle).

Area of Rectangle:
A= 21in x 16in = 336in^2

Area of Circle:
A = pi * r^2
A = 3.14 * (8in)^2
A = 3.14 * 64in^2
A = 201in^2

Subtracting the non shaded region from the area of the rectangle:
336in^2 - 201in^2 = 135in^2

Therefore, the answer is 1. 135in^2

The first thing you would do is find the area of the rectangle.

To find the area of a rectangle you would use length x width

So it already gives you the length which is 21, now you can find the width by looking inside at the radius of the circle (8). That would be half of the width. Which means we would multiply 8 by 2.

8 x 2 = 16 so the width is 16. Now the only thing left to do is to multiply the width times the height.

16 x 21 = 336

The area of the rectangle is 336.

Next we need to find the area of the circle.

To find the area of a circle you would do Pi x r^2

The radius is 8. 8^2 = 64 then multiply that by Pi (3.14)

64 x 3.14 = 200.96

We have the area of the rectangle and the circle. The only thing left is to subtract the area of the circle from the area of the rectangle.

336 - 200.96 = 135.04

The answer would be 1. 135 in^2
