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

what’s the hypotenuse

Answers

answer: 13 cm

explanation:
pythagorean theorem to find the hypotenuse ( which is c)
a^2 + b^2 = c^2
let’s just say a=5 and b = 12
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2 -> take the square root of both sides
√169 = √c^2
c = 13

OR you can memorize a few pythagorean triples and know 13 is the hypotenuse bc 5-12-13 is a pythagorean triple so 13 is the hypotenuse

Answer:13

7 + x/5 = -4
What is x?

Answers

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.

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?

Answers

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

Answers

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

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]
