What is mass?

Anything that occupies space is said to have acquired mass. That means quantitative measure of inertia, a fundamental property of all matter.

How to solve?

Given mass of 1 match box=20g

Mass of match box alone = 8 g

Mass of match box if it has 6 matches= 20-8(weight of matches)

If box has 20 matches in all 1 match will have mass of 1 gm then 6 matches will have mass of 6 matches.

#SPJ2

Each match has a mass of 2 g. This is because you must take the matchbox's total mass and subtract the mass of the box alone. You get 12, and then you divide by 6 to find the amount of each match

Find the value of z

Answers

Answer:

C. 50

Step-by-step explanation:

We are given ΔABC with an altitude BD as shown in the figure.

As it is known that,

'When an altitude is drawn from a right angle of a triangle, then all the three triangles are congruent.'

So, we get that ΔABC ≅ ΔABD ≅ CBD.

Since, the triangles are congruent, their corresponding sides and angles will be congruent.

Moreover, the ratio of the sides will be equal.

So, we get from ΔABC ≅ ΔABD,

$(AD)/(AB)=(AB)/(AC)$

i.e. $AD=(AB* AB)/(AC)$

i.e. $18=(30* 30)/(z)$

i.e. $18=(900)/(z)$

i.e. $z=(900)/(18)$

i.e. z = 50.

Hence, the value of z is 50.

Light travels at 186,000 miles per second. Light takes about 11⁄3 seconds to travel from the earth to the moon. Calculate the distance between the earth and the moon based on the speed of light.

Answers

To answer the question above, multiply the speed of light with the time it takes to travel from earth to the moon. In this given, the product of the speed of light, 186,000 miles per second and 11/3 seconds is 682, 000 miles. Thus, based on the speed of light, the distance between the earth and moon is 682, 000 miles.

Answer:

The correct answer is:

186,000 x 1 1⁄3 = 248,000 miles

4/5+×=13/5 how do I solve this problem

Answers

Subtract 4/5 from each side.
You get x=9/5
For future problems like this, use the inverse operations.

Like if it is 5x=25, divide by 5.
x=5
For this x=9/5 though

How do you solve 5x+7=3x-5

Answers

5x + 7 = 3x - 5

First, subtract 3x from both sides.
$5x = 7 - 3x = -5$
Second, keep the 7 and subtract the 5x - 3x to get 2x.
$2x + 7 = -5$
Third, subtract the 7 from both sides.
$2x = -5 - 7$
Fourth, simplify -5 - 7.
$2x = -12$
Fifth, take the 2 and divide it on both sides, leaving just x in its place.
$x = -(12)/(2)$
Sixth, since 6 goes into 2 to get 12, simplify the fraction to 6.
$x = -6$

Answer: x = -6

Subtract 3x from both sides then isolate the variable.
Sooooo...
5x+7=3x-5
2x+7=-5
2x=-12
x=-6
