(85 + 84 + 78 + x) / 4 = 86
(247 + x) / 4 = 86
247 + x = 86 * 4
247 + x = 344
x = 344 - 247
x = 97 <=== her score was 97
Lateral area around don't count the ends that are triangle
Bottom is 9 times 47= 423
Right side 9.23 times 47= 433.81
Left side 2 times 47= 94
Total lateral area = 950.81
Triangles 1/2 (9)(2)(2)=18
Total surface area= 968.81
Answer:
The vine is growing faster than the tree.
Step-by-step explanation:
According to the chart, the Slope-intercept form of the tree is y = 4x + 2.
The slope intercept of the vine is y = 5x + 3. Therefore, the vine is growing at a faster rate.
Answer: cardiac output=11,250ml/min
Step-by-step explanation: Cardiac output = Heart rate(beats/min) × stokes volume (ml/beat)
Cardiac output = 125 ×(130 -40)
Cardiac output= 125×90 =11,250ml/min
Prime factorization: 84 = 2 x 2 x 3 x 7 which can also be written 2² x 3 x 7.
