Find the area of the shape.
Answer:
39.5 [tex]ft^{2}[/tex]
Step-by-step explanation:
We need to take this shape by shape
Top triangle
a = b*h/2
a = 3*2/2
a = 6/2
a = 3
__________________________________________________________
Bottom triangle:
a = b*h/2
a = 3*3/2
a = 9/2
a = 4.5
__________________________________________________________
Rectangle:
a = b*h
a = 8*4
a = 32
__________________________________________________________
Now add them all up
3 + 4.5 + 32 = 39.5
The area of the shape is 39.5 [tex]ft^{2}[/tex]
Hope this helped!
A baseball is hit along the third base line with a speed of 100 ft/s. At what rate is the balls distance from first base changing when it crosses third base?
Solution :
From the triangle,
[tex]$x^2 = s^2 + 90^2$[/tex]
[tex]$x = \sqrt{s^2 + 90^2}$[/tex]
Now differentiating w.r.t "t", we get
[tex]$\frac{dx}{dt}=\frac{d}{dt}\left(s^2 +90^2 \right)^{1/2}$[/tex]
[tex]$=\frac{1}{2}\left(s^2 + 90^2 \right)^{\frac{1}{2}-1} \cdot 2s \cdot \frac{ds}{dt}$[/tex] [chain rule]
[tex]$=\frac{1}{2}\left(s^2 + 90^2 \right)^{-\frac{1}{2}} \cdot 2s \cdot \frac{ds}{dt}$[/tex]
[tex]$=\frac{s}{\left(s^2 + 90^2\right)^{\frac{1}{2}}} . \frac{ds}{dt}$[/tex]
But given that [tex]$\frac{ds}{dt}$[/tex] = 100 ft/s
When all the ball crosses the third base, this means that s = 90. So substituting the value of s and [tex]$\frac{ds}{dt}$[/tex] in [tex]$\frac{dx}{dt}$[/tex] , we get
[tex]$\frac{dx}{dt} = \frac{90}{\left(90^2 +90^2\right)^{1/2}} \times 100$[/tex]
[tex]$\frac{dx}{dt} = \frac{90}{\sqrt{8100+8100}} \times 100$[/tex]
[tex]$\frac{dx}{dt} = 50\sqrt2$[/tex]
= 70.710 ft/s

Han has Spent 75 minutes practicing the piano over the weekend priya practice the violin for 152% as much time as hand practicing piano how long does she practice
Answer: 114 minutes
Step-by-step explanation:
From the question, we are informed that Han has Spent 75 minutes practicing the piano over the weekend while Priya practice the violin for 152% as much time as Han used in practicing the piano.
Therefore, the number of minutes used in practicing by Priya would be gotten by multiplying 152% by 75 minutes. This would be:
= 152% × 75 minutes.
= 152/100 × 75minutes
= 1.52 × 75 minutes
= 114 minutes

Answer: 1.23
Step-by-step explanation:
0.3*4.1=
Answer:
It is 1.23
Step-by-step explanation:
When multiplying decimals, multiply it as a whole number, and move the decimal to the left the amount of times it was in the problem.
i.e. .3 times 4.1
.3 has 1 number behind the decimal and 4.1 also has one number behind the answer. This means that you will move the decimal to the left twice in 123.0 to 1.23

7 + x/5 = -4
What is x?
Answer:
x = -55
Step-by-step explanation:
Subtract 7 on both sides first to get to this equation, x/5 = -11. Since there is a fraction on the left side, you have to multiply 5 on both sides to get your x-value which is -55.
