Answer:

18 like both.

Step-by-step explanation:

If there are 50 students and 3 like neither math or physics, then 47 of them either like one or both of the subjects. Adding up the 30 and 35, we get that 65 of the students like the two subjects collectively. Well that’s not right. We have overcounted the 65–47=18 students who like both subjects. Thus, 35–18=17 students only like physics.

Check: We have 3 students who like neither, 18 who like both, 17 who like just physics, and 30–18=12 who just like math. Adding them up, we have 18+17+12+3=50 students all togtether

What is the measure for the following ∠?<br> m∠EOD<br><br> 20<br> 120<br> 140
Eddi Din [679]

Answer:

Part 1) m∠EOD=20°

Part 2) m∠AOD=80°

Step-by-step explanation:

Part 1) Find the measure of angle EOD

we know that  °

m∠EOD=m∠EOX-m∠DOX

we have

Observing the figure

m∠EOX=140°

m∠DOX=120°

substitute

m∠EOD=140°-120°=20°

Part 2) Find the measure of angle AOD

we know that  °

m∠AOD=m∠DOX-m∠AOX

we have

Observing the figure

m∠AOX=40°

m∠DOX=120°

substitute

m∠AOD=120°-40°=80°

For a moving object, the force acting on the object varies directly with the objects acceleration. When the force of 63 N acts o
Serjik [45]

Answer:

49N

Step-by-step explanation:

Step one

Given

When the force of 63 N acts on a certain object

the acceleration of the object is 9/ms^2

Firstly, we need to calculate the mass m

F=ma-------1

m= F/a

m= 63/9

m= 7kg

Step two:

Also, if the acceleration of the object becomes 7 m/s^2

then the force

Note: the mass remains the same= 7kg

F=ma

F=7*7

F= 49N

A wheel turns through 200 revolutions per minute. How fast does it turn in radians per second?
lana [24]

Answer:

In one second it turns 200 / 60 = 3 1/3 revolutions. Since one revolution is 360°, the answer is 6 2/3 π radians.
