An 8 inch pizza is cut into 4 equal slices. A 10 inch pizza is cut into 6 equal slices. Which slices are larger?

The 8 inch one
8/4=2
10/6= approx 1.66666666666666
They 8 inch pizza. It sounds as though the 10 inch one is, but it actually isn't. The 8 inch pizza has bigger slices because it is sliced into 4 pieces.

Over the last three evenings, Susan received a total of 95 phone calls at the call center. The first evening, she received 5 fewer calls than the third evening. The second evening, she received 3 times as many calls as the third evening. How many phone call did she receive each evening?

Night one: 15 calls

Night two: 60 calls

Night three: 20 calls

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

Well, we would simply make an equation.

We're saying the third evening she got x calls.

x-5+3x+x=95

You would need to simplify.

5x-5=95

5x=100

x=20

Night one: 15 calls

Night two: 60 calls

Night three: 20 calls

What doesn't the law of cosines reduce to when dealing with a right triangle

The Pythagorean theorem
The Pythagorean Theorem

The area of a square garden is 128m sqared.how long is the diagonal

The area of a square is  (side)².
If the area is  128m², then the side is  (√128) meters. (That's 8√2.)

The diagonal is the hypotenuse of the right triangle you get
if you slice the square in half along the diagonal.  Its length is
given in the words of Old Pythagoras:

c² = a² + b²

'a' and 'b' are sides of the square, so

c² = (√128)² + (√128)²

=    2 (√128)²

c  =  √ (2 x 128)  =  √256  =  16 meters .

The length will be the square root of 128.  Factoring out a 64, this is 8sqrt(2).  To find the diagonal of square, multiply the length by sqrt(2), for a result of 8sqrt(2)*sqrt(2)=8*2=16.

Help plz Eleven students are lined up at the drinking fountain. Every other student is a boy. The first, third, fifth, and seventh students are boys. Which other ones are boys?

The 9th and 11th students are also boys.

Step-by-step explanation:

Every other student is a boy. Since the 7th student is a boy this means the 8th student is a girl.

You can also think of it with odd numbers. Every odd numbered student is a boy.

Ninth and eleventh because its every odd number

Step-by-step explanation:

7. Erika's hourly wage is \$10. She works 35 hours a week. What is her weekly income? What is her monthly
income? If Erika pays 30% of her income for rent every
month, what does she pay?

Monthly income = 350*4= \$1400

Rent = 30%*1400

=\$420

Step-by-step explanation:

1.A line is parallel to the line 5x+y+4=0 Work out it's gradient (The answer is a whole number or decimal.) 2.Another line is parallel to the line 3x+5y=15 Work out it's gradient. (The answer is a fraction)

If we arrange the equation of a line in standard form,

1).                                            5x + y + 4  =       0

Subtract  4  from each side:    5x + y        =       -4

Subtract  5x  from each side:          y        = -5x - 4

The slope (gradient) of the line is  -5 .

2).  Parallel lines have the same slope (gradient).
First, find the slope (gradient) of the given line.

3x + 5y =              15

Subtract  3x  from each side:    5y = -3    x + 15

Divide each side by  5 :              y = -3/5 x + 15

The slope (gradient) of the given line is  -3/5 .
Any line with a slope (gradient) of  -3/5  is parallel to this one.

Its equation will be         y = -3/5 x  +  any number.
