Use the first three triominoes to find the missing number in the fourth triomino. –7 –9 –11 –13

Molodets [167]

Answer:
-9

Explanation:
From the first three triominoes, we can note that:
number on center = -first base - second base + vertex

This is verified as follows:
For the first one:
The two bases are 7 and 9 and the vertex is 1
- first base - second base + vertex = -7 -9 + 1 = -16 + 1 = -15

For the second one:
The two bases are 0 and 9 and the vertex is 8
- first base - second base + vertex = -0 -9 + 8 = -9 + 8 = -1

For the third one:
The two bases are 6 and 4 and the vertex is 2
- first base - second base + vertex = -6 - 4 + 2 = -10 + 2 = -8

Applying the same procedure on the last one:
The two bases are 7 and 2 and the vertex is 0
-first base - second base + vertex = -7 - 2 + 0 = -9 + 0 = -9

Hope this helps :)

In an endurance race, Rachel ran

Reil [10]

Answer:

$31\frac{1}{5}\ miles$

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

The distance is equal to multiply the speed by the time

we have

$speed=9\frac{3}{5}\ \frac{miles}{hour}$

$time=3\frac{1}{4}\ hours$

$distance=(9\frac{3}{5})(3\frac{1}{4})$

Convert mixed number to an improper fraction

$9\frac{3}{5}=9+\frac{3}{5}=\frac{9*5+3}{5}=\frac{48}{5}$

$3\frac{1}{4}=3+\frac{1}{4}=\frac{3*4+1}{4}=\frac{13}{4}$

substitute

$distance=(\frac{48}{5})(\frac{13}{4})=\frac{624}{20}=31,2\ miles$

Convert to mixed number

$31.2\ mi=31+0.2=31+\frac{1}{5}=31\frac{1}{5}\ miles$
