400 is 1/10 of what is the answer to this one plz n this one two 60 is 1/10 of

RideAnS [48]

400 would be 1/10 of 4,000 because you would divide 400 by 1/10 to get 4,000 and 60 is 1/10 of 600 because you would divide 60 by 1/10 to get 600.

If 3t-7=5t then 6t =

dusya [7]

$3t-7=5t\ \ \ \ |add\ 7\ to\ both\ sides\\\\3t=5t+7\ \ \ \ \ \ |subtract\ 5t\ from\ both\ sides\\\\-2t=7\ \ \ \ \ |divide\ both\ sides\ by\ (-2)\\\\t=-3.5\\\\6t=6\times(-3.5)=-21$

Let tan theta= 5/12, where sin theta> 0.<br>Find the exact value of sec theta

soldier1979 [14.2K]

Answer:

5/13

Step-by-step explanation:

1. We are given tan(x)=5/12 .....(2)

2. On comparing the quantities we get that p=5 and b=12

3. We require the value of hypotenuse(h),

for this we apply the Pythagoreum theorum: p^2+b^2=h^2

⇒h^2=5^2+12^2

⇒h^2=25+144

⇒h^2=169

⇒ h=√169

⇒ h=13

Sin=p/h

p=5

h=13

Sin=5/13

Raquel has created a program for a robot. The robot travels 10 meters and stops. The program is designed for wheels that are 2.5

Grace [21]

Answer:

Raquel should adjust the number of rotations to 115.81 rotations

Step-by-step explanation:

step 1

Find the circumference of the wheels that are 2.5 cm in diameter

The circumference is equal to

$C=2\pi r$

we have

$r=2.5/2=1.25\ cm$

assume

$\pi =3.14$

substitute

$C=2(3.14) (1.25)$

$C=7.85\ cm$

step 2

Find the number of rotations

Divide 10 meters by the circumference

$10\ m=1,000\ cm$

$1,000/7.85=127.39\ rotations$

step 3

For a diameter of 2.75 cm find how should she adjust the number of rotations so that the robot travels the same distance

Find the circumference of the wheels

The circumference is equal to

$C=2\pi r$

we have

$r=2.75/2=1.375\ cm$

assume

$\pi =3.14$

substitute

$C=2(3.14) (1.375)$

$C=8.635\ cm$

step 4

Find the number of rotations

Divide 10 meters by the circumference

$10\ m=1,000\ cm$

$1,000/8.635=115.81\ rotations$
