The triangles shown below must be congruent.

Ber [7]

Answer:

False

Step-by-step explanation:

The triangles are similar because the angles are the same

180kg, 250kg, 200kg, 209kg, 195kg, 205kg, 190kg, 188kg, 192kg. What is the IQR of the lion's weights.

velikii [3]

Answer:

Step-by-step explanation:

Given the data:

180kg, 250kg, 200kg, 209kg, 195kg, 205kg, 190kg, 188kg, 192kg

The interquartile range (IQR) = Q3 - Q1

Reordering the data:

180, 188, 190, 192, 195, 200, 205, 209, 250

Q3 = 3/4(n+1)th term

Q3 = 3/4(10) = 7.5 th term = (205+209)/2 = 207

Q1 = 1/4(n+1)th term

Q1 = 1/4(10) = 2.5th term = (188+190)/2 = 189

Q3 - Q1 = 207 - 189 = 18

A recipe calls for 1 part beans to 1½ parts rice. if 1½ parts of beans are used, how much rice should be used?

riadik2000 [5.3K]

$1 \text{ part beans} \longrightarrow 1\dfrac{1}{2} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow 1\dfrac{1}{2} \times 1 \dfrac{1}{2} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow \dfrac{3}{2} \times \dfrac{3}{2} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow \dfrac{9}{4} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow 2\dfrac{1}{4} \text{ parts rice}$
