Answer:
b) 5:7 = 15:21
Step-by-step explanation:
This questions tests our understanding of enlargement ratios.
#Determine the decimal equivalents or simplify to see which one is correct:
#a) 5:21 = 7:15
#b) 5:7 = 15:21
#c) 5:7 = 21:15
#d) 21:5 = 15:7
Hence, option b is the correct one as 5:7 = 15:21
6. 40 minutes (15/3 = 5 minutes/mile) - 5*8 = 40 min
7. 15,840 ft / 5 = 3.168 ft
Answer:
total area = 39.6 square units
Step-by-step explanation:
determine the inside angle
360 / 5 = 72°
half of the triangle = 36°
given:
adj = 3.3
Ф = 36°
length of the opp of a small triangle is = adj. tan Ф
opp = 3.3 * tan 36 = 2.4
area of a triangle = 1/2 b * h x 2 tringles
area =( 1/2 * 2.4 * 3.3 ) * 2
area = 7.92 multiplied by 5 equal shapes
total area = 7.92 * 5
total area = 39.6 square units
hope this helps
Answer:
The correct answer is D.
Step-by-step explanation:
When dividing -4 on both sides, the correct result becomes 8 is greater than or equal to <em>z</em><em>.</em><em> </em>This also means that the result of <em>z</em><em> </em>must be less than or equal to 8, so the graph also represents a closed point at 8 with the ray pointing towards the left with each result less than 8.
Answer: 7
Explanation: plus 8 to 34 so you have
42 = 6d and then divide 42 by six and 6d divided by 6 too you get 7 = d
