210 divided by 3 equals 70
210+70= 280
$2.80
Answer:
The length of SO is 46 units
Step-by-step explanation:
<em>In a parallelogram, </em><em>diagonals bisect each other,</em><em> which means meet each other in their mid-point</em>
∵ SNOW is a parallelogram
∵ SO and NW are diagonals
∵ SO ∩ NW at point D
→ That means D is the mid-point of SO and NW
∴ D is the mid-point of SO and NW
∵ D is the mid-point of SO
→ That means D divide SO into two equal parts SD and DO
∴ SD = DO
∵ SD = 9x + 5
∵ DO = 13x - 3
→ Equate them
∴ 13x - 3 = 9x + 5
→ Subtract 9x from both sides
∵ 13x - 9x - 3 = 9x - 9x + 5
∴ 4x - 3 = 5
→ Add 3 to both sides
∵ 4x - 3 + 3 = 5 + 3
∴ 4x = 8
→ Divide both sides by 4
∴ x = 2
→ To find the length of SO substitute the value os x in SD and DO
∵ SO = SD + DO
∵ SD = 9(2) + 5 = 18 + 5 = 23
∵ DO = 13(2) - 3 = 26 - 3 = 23
∴ SO = 23 + 23 = 46
∴ The length of SO is 46 units
The Blue line is the translate in the direction of red line by,and therefore has equation y=3(x-4)+5
Answer:
Step-by-step explanation:
The first statement is correct. The volume of this rectangular prism is v = l*w*h, and so 495 cm^3 = (12*2.5 cm^2)*h is correct.
To find h, Zoe should divide 495 cm^3 by (12*2.5 cm^2), so the second statement is wrong.
The third statement is incorrect, due to an arithmetic error. 495 cm^3 divided by (12*2.5 cm^2) is 16.5 cm, not 15.5 cm. Thus: the missing height, h, is 16.5 c.m.
