CAN SOMEONE PLEASE HELP ME WORTH 20 points

Mathematics
1 answer:
Ainat [17]3 years ago
5 0

Answer:

  12 units

Step-by-step explanation:

Point H is the intersection of the medians, so divides each median into parts with the ratio 2:1. Here, that is ...

  CH : HG = 2 : 1 = CH : 6

Then CH = 2×6 = 12.

_____

Alternatively, you could determine altitude CG from the Pythagorean theorem applied to triangle BCG. You would compute ...

  CG² +GB² = BC²

  CG = √(BC² -GB²) = √(19.8² -8²) = √146.7 ≈ 12.1

This is an approximation based on the fact that the value 9.9 for BF is an approximation. Based on BG and GH being integer values, the appropriate measure of BF is (√388)/2 ≈ 9.8489.

(The triangle shown cannot exist.)

I believe the answer is C - 60 inches. 60 x 2 = 120, which is both lengths, and since he width is half the length, then 30 x 2 = 60. So 130 (length) + 60 (width) = 180. So 60 inches would be the maximum length for both sides.

Answer:

  b.  9/100

Step-by-step explanation:

It helps if you have memorized the cubes of small integers. Of course, the ones needed here are ...

  3³ = 27

  10³ = 1000

The desired value can be simplified to ...

  \left(-\dfrac{1000}{27}\right)^{-2/3}=\left(-\sqrt[3]{\dfrac{3^3}{10^3}}\right)^2=\dfrac{(-3)^2}{10^2}=\dfrac{9}{100}

rusak2 [61]
Answer: 6x=42

Explanation: After the step 6x+6=36, it’ll equal 6x=30 because when you subtract the 6 on both sides, it’ll equal 30, revealing it’s actually 6x=30, with the conclusion of x=5.

If L | | m and m&lt;8 = 109°, what is m&lt;5
Karolina [17]

Answer:

m∡5 = 71°

Step-by-step explanation:

m∡8 = m∡6

m∡6 + m∡5 = 180

180 - m∡6 = m∡5

180 - 109 = 71

The Jones family has 3 children.
Lubov Fominskaja [6]
Amy = x
Betty = y
Carl = z
x + y = 29
x + z = 27
y + z = 22
y = 29 - x
z = 27 - x
29 - x + 27 - x = 22
-2x + 56 = 22
-2x = - 34
x = 17
y = 12
z = 10
Oldest child is Amy (17) and youngest child is Carl (10)
17 - 10 = 7
The difference between oldest child and youngest child is 7 years.
