360 degrees in a circle

360 degrees minus 90 degrees (the right angle of the square) = 270 degrees

270 degrees divided by 2 = 135 degrees

f = 135 degrees

Which unit is not a measurement of volume? cm L ml cm3

Dahasolnce [82]

Volume is 3 dimentional

cm is 1 dimentional: legnth
L=liters=volume=cubic meter
ml=mililiter=volume=cubic centimeter
cm^3=mililiter

cm is the answer

weight is the measurement of the amount of gravity of an object, it changes depending on where you are (on moon, something has less weight than on earth)
mass is how much matter is in something, doesn't matter where you are (on moon, still same mass as on earth)
FALSE

Calculate the perimeter of a rectangle which is 11 metres long and 4 metres wide

mote1985 [20]

To calculate the perimeter of a rectangle what you would do is add the parallel sides together so 11+11=22 and then 4+4=8 so we would add 22+8=30

So your answer would be 30

Multiply and give the answer in scientific notation:

kakasveta [241]

Step-by-step explanation:

given

$(1.5 \times {10}^{4} )(8 \times {10}^{8} )$

in order to make multiplication easier we need to change the 1.5 into a whole number form.

thus

$(15 \times {10}^{ - 1} \times {10}^{4} )(8 \times {10}^{8} )$

$= (15 \times {10}^{4 - 1} )(8 \times {10}^{8} )$

First law of indices applied there

=(15×10^3)(8×10^8)

=(15×8)(10^3×10^8)

=120×10^3+8 ( first law of indices, which states that , numbers of the same base multiplying each other, take one of the base and add the exponent. and clearly both 15 and 8 are in base 10

=120×10^11

=1.20×10^2 ×10^11

=1.20×10^11+2

=1.20×10^13

so the answer is alt B

Lilly made a 89 on her Math test. The test had 26 questions, how many questions did she miss?

anygoal [31]

She missed 3 questions,

11/100 equals x/26
^set up this proportion
you get 286 equals 100x
and x equals 2.86

round this to 3 questions

to check your work, do 23/26
