7

a trapezoid

equation for area = h(a +b) ÷ 2

so you sub that in

8(9 +21) ÷ 2 = 8 × 30 ÷ 2 = 120

so the area is 120cm

8

A trapezoid

equation for area = h(a +b) ÷ 2

so you sub that in

6(9 + 5 ) ÷ 2 = 6 × 14 ÷ 2 = 42

So the answer is 42 inches

9

A kite

equation for area = p× q ÷ 2

so you sub that in

(3+3)×(4.5+6.5) ÷ 2 = 6×11÷2 = 3

So the answer is 33 cm

sorry I can't see 10s measurements

Below is the graph of f9x0= 2in(x) how would you describe the graph of g(x) = 4in(x)?
FinnZ [79.3K]
Please, next time, please share the graph referred to in the problem statement.

You are comparing f(x)=2 ln x and g(x) = 4 ln x.  The two graphs look the same, except that the amplitude (rise) in 4 ln x is exactly twice that in 2 ln x.

Thus, if 2 ln x = 3, 4 ln x = 2(3) = 6.

Of the 30 students in the sixth period math class, 8 are also in the same fourth period science class. Which can be used to dete
Kazeer [188]

Answer:

A. (8/30)(22/29)(21/28)

Step-by-step explanation:

The key is in reading the question really thoroughly, like, way more than you would expect. The <em>first</em> person is from the group of 8, thus (8/30), but the other <em>two</em> <u>cannot</u> be from the group of 8. 30(students total) minus 8 (the 8 people from science class)=22 (remaining in math). You choose one person who is <em>not</em> from the group of 8, and you are left with 21 other people. The number of students available to be in a group goes down each time: 30 down to 29 down to 28 (the denominators). Kaboom, A. (8/30)(22/29)(21/28).

The ratio is 8:9 is the ratio between 0.45 - 0.60?
bagirrra123 [75]

Divide 8 by 9

8 / 9 = 0.888

0.88 is greater than 0.60 so it is not between 0.45 - 0.60
