Bas_tet [7]

$\\ \rm\longmapsto Area=255m^2$

$\\ \rm\longmapsto LB=255$

$\\ \rm\longmapsto 9L=255$

$\\ \rm\longmapsto L=\dfrac{255}{9}$

$\\ \rm\longmapsto L=28.3m$

What kind of sequence is the pattern 15, 17, 20, 24, 29,

VikaD [51]

$\implies {\blue {\boxed {\boxed {\purple {\sf { \: 15, 17, 20, 24, 29,35, 42}}}}}}$

$\sf \bf {\boxed {\mathbb {Step-by-step\:explanation:}}}$

$\: 15, 17, 20, 24, 29,35, 42$

➺ $\: 15 + 2 = 17$

➺ $\: 17 + 3 = 20$

➺ $\: 20 + 4 = 24$

➺ $\: 24 + 5 = 29$

➺ $\: 29 + 6 = 35$

➺ $\: 35 + 7 = 42$

Tanner is picking three varieties of apples at an orchard: Gala, Fuji, and Jazz. Each type of apple has a different cost per pou

Makovka662 [10]

Answer:

2g + 2f = 5.16

7g + 9f = 21.24

Step-by-step explanation:

Let

Gala = g ; Fuji = f ; jazz = j

g + f + j = 5.16 - - - (1)

j = g + f - - - (2)

From (1):

g + f + g + f = 5.16

2g + 2f = 5.16 - - - (3)

Total pound picked by Tanner = 12

3 Pounds of g ; 5 pounds of f

j = 12 - (5 +3) = 4 pounds

3g + 5f + 4j = 21.24 - - - (4)

3g + 5f + 4(g + f) = 21.24

3g + 5f + 4g + 4f = 21.24

7g + 9f = 21.24 - - - - - (5)

Find the value of y 74 77 89 96

Morgarella [4.7K]

The external angle (53°) is half the difference of the intercepted arcs (y°, 180°), so we have
53 = (180 - y)/2
106 = 180 - y
y = 180 - 106
y = 74

The appropriate choice for the value of y is ...
74
