One quarter weighs about 5.67 grams.

5.67 x 32 = 181.44 grams

Grams to kg = .001

181.44 x .001 = .18144 kg

Answer:

78.5%

Step-by-step explanation:

The area of the square is equal to diameter squared

i.e 4 in × 4 in = 16 square inches

The area of the circle is π × r²

i.e π × 2² = 12.56637061

The percent of the time the point will be in the circle = (Area of the circle) ÷ (Area of the square) × 100

i.e \frac{12.56637061}{16} × 100 = 78.53981631%

And is equal to 78.5% (rounded up to the nearest tenth of a percent)

Solve this system of linear equations. separate x and y values with a comma. 7x=-67-11y 5x=-73-11y​
Aleks [24]

Answer:

3, -8

(x is equal to 3 and y is equal to -8)

Step-by-step explanation:

<u>The system:</u>

{ 7x=-67-11y

{ 5x=-73-11y​

<u>Finding a value for x:</u>

7x=-67-11y -> x = -\frac{67}{7} - \frac{11y}{7}

<u>Solving for y by plugging in our x:</u>

[Equation] 5x = -73 -11y​

[Plug-in] 5(-\frac{67}{7} - \frac{11y}{7}) = -73 -11y​

[Distribute the 5] -\frac{335}{7} - \frac{55y}{7} = -73 -11y​

[Multiply by 7] 7 (-\frac{335}{7} - \frac{55y}{7}) = (-73 -11y​) 7

[Simplify] -335 - 55y = -511 - 77y

[Add 335 and 77y to both sides] 22y = -176

[Divide by 22] y = -8

<u>Plug in our y to solve for x:</u>

5x = -73 -11y​

5x = -73 -11(-8)

5x = -73 + 88

5x = 15

x = 3

Have a nice day!

13. 2 – (–8) + (–3) = <br><br> A. 1<br> B. 12<br> C. 7<br> D. 14
baherus [9]

ANSWER

C. 7

EXPLANATION

We want to evaluate

2 - (  - 8) + ( - 3)

We use the order of operations PEDMAS.

Dealing with the parenthesis first,we have

2  -  - 8+- 3

Note that:

-    -  =  +

and

-  +  =  -

Our expression now becomes:

2 + 8 - 3

Next, we add to get:

10 - 3

We finally subtract to get,

7

The correct answer is C
