Answer:
Step-by-step explanation:
Part A.
Expression
= 10
Because 100 =
and ![[(10)^2]^{\frac{1}{2}}=10^1=10](https://tex.z-dn.net/?f=%5B%2810%29%5E2%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D10%5E1%3D10)
[Since,
]
Part B.
When simplified, the answer is RATIONAL.
[Since, 10 can be written as

Answer:
y = 102*x
Step-by-step explanation:
y=a*x
x: distance
y: calories
816=a*8
a= 816/8= 102
Answer:
The vertical component of the force correct to the nearest pound Is
1352 pound
Step-by-step explanation:
Kindly find attached for your reference
This problem bothers on the topic of work energy and power
Given data
Applied force = 3200 pounds
Angle of application = 25°
We know that the horizontal force =
F= 3200cos 25°
Hence the vertical component of this force = F= 3200sin 25
=3200*0.42261
= 1352.352
to the nearest pound
F = 1352pound
Let the initial number of girls be x, this represents 40% of the dancers.
Total number of dancers will therefore be:
100/40*x=2.5x
When 15 more girls joined, the new number of girls was:
x+15 this represents the total percentage of 52%. The new number of dancers became:
2.5x+15:
therefore the new percentage of girls can be expressed as follows:
(new number of girls)/(new number of dancers)×100
(x+15)/(2.5x+15)×100=52
(x+15)/(2.5x+15)=0.52
x+15=0.52(2.5x+15)
x+15=1.3x+7.8
15-7.8=1.3x-x
7.2=0.3x
x=7.2/0.3=24
The number of students after additional number of girls will be:
2.5x+15
=2.5×24+15
=60+15
=75 students
