Answer:
m<A = 75 and m<B = 105.
Step-by-step explanation:
To find the two angles, we first take 180 (because supplementary angles are two angles that add up to 180) and we divide it by 2 to get 90. Then we take 30 degrees and divide that by 2 to get 15. You add 15 degrees to measure B and subtract 15 degrees to measure A. So then you get m<A = 90 - 15 = 75 and m<B = 90 + 15 = 105.
Answer:
8 weeks
Step-by-step explanation:
p = 2w
p = total pieces = 16
then putting value in p = 2w
16 = 2w
divide by 2 on both side we get
16/2 = 2w/2
8 = w
where w is total weeks i.e 8
Answer:
9/4
Step-by-step explanation:
2 1/4 = 9/4 From mixed fraction to an improper fraction: "the numerator of the improper fraction" = "denominator" xx "the whole number" + "the numerator of the mixed fraction" The denominator remains as it is. So 2 1/4 = (4 xx 2 + 1)/4 = 9/4
Answer:
4/6 or simplifed to 2/3
Step-by-step explanation:
To find half of anything, you are dividing by 2 or multiplying it by 1/2.
If you are working in fractions, it's easier to do the later (multiplying by 1/2)
So you have 1 1/3 cups of walnuts being multiplied by 1/2.
You should convert any mixed number to an improper fraction first before multiplying or dividing with another fraction.
1 1/3 Mixed number = 4/3 as an improper fraction
So now you can use 4/3 x 1/2
To multiply fractions, you just multiply the numerators together then put that over multiplying the denominators together.
4x1 over 3x2
= 4/6
