(68 heart beats) and (minutes) so therefore it is an example

There are two variables here, which are time (minutes) and the number of beats, and they both have a relationship (68 beats in one minute), therefore it is an example of a unit rate

Find the area of the shaded region.<br> help pls
umka2103 [35]

Answer:

1. 50 m

2. 80 cm

Step-by-step explanation:

1. There are 2 triangles, subtract the area of 1 of them from the other.

The triangle that needs to be subtracted: b = 20 m, h = 10 m

A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m

The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150

150 - 100 = 50 c

2. Divide it into 3 parts:

1- 3*4 = 12

2. 7*(4 + 4) = 7*8 = 56

3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12

12 + 56 + 12 = 80 cm

2/3 divided by 11/15
NNADVOKAT [17]
You need to implement the process of "flip-flop" and multiply which is where you flip the second fraction and multiply.

\frac{2}{3}÷\frac{11}{15}⇒\frac{2}{3}×\frac{15}{11}

Now you multiply across. 2×15=30 and 3×11=33

So now it is \frac{30}{33}

-----------------------------------------------------------
To reduce to the lowest terms, find the GCF common factor

The GCF is 3

Divide both the numerator and denominator by 3

\frac{30}{33}÷\frac{3}{3}=\frac{10}{11}

Answer: \frac{10}{11}
