Mathematics
1 answer:
irakobra [83]2 years ago
7 0

Ok, lets start with the top.

7/8 + (-2/3)

Thats equal to

7/8 - 2/3

The common denominator will be 24

21/24 - 16/24

Subtract

5/24

Now, to divide you multiply by the reciprocal, so

5/24 / 5/6

Becomes

5/24 * 6/5

Cross simplify and get your answer

1/4

Do the ratios 9/4 and 11/6 make a proportion please explain. Thank You!
svetoff [14.1K]
No they're not proportionate because 9 divided by 4 = 2.25 and 11 divided by 6 is 1.83 so they're not the same in value

JKL is a straight line.
kirza4 [7]

Answer:

x = 32°

Step-by-step explanation:

∆KLM is an isosceles triangle because it has two equal sides, KL & KM. Therefore, the angles opposite to each of the two equal sides, which are referred to as the base angles are congruent to each other.

m<KML = m<KLM = 58°

m<MKL = 180 - (58 + 58) (Sum of triangle)

m<MKL = 64°

m<JKM = 180 - m<MKL (linear pair theorem)

m<JKM = 180 - 64 (Substitution)

m<JKM = 116°

∆JKM is also an isosceles triangle with two equal sides. Therefore, it's based angles (x & <J) would also be equal to each other.

Thus:

x = ½(180 - m<JKM)

x = ½(180 - 116) (Substitution)

x = 32°

How are u supposed to find the area only with the circumference?
seraphim [82]

Answer:

We can find the radius from circumference and then area

Circumference(C) = 2πr

r = C/2π

r = 20/2π

r = 10/π

Area = πr²

Area = π × 10/π × 10/π

Area = 100/π

Area = 100/3.14

Area = 10000/314 = 31.84 cm² (approx)

Area = 32 cm² (Rounding to nearest whole number)
