The following formula relates three quantities Force (F) mass (m) and acceleration (a).

Agata [3.3K]

a. F = ma

F/a = ma/a

m = F/a

b. F = ma

-30 = -6a

a = 5

c. F = ma

30 = 10a

a = 3

Convert to length 2.1 cm to mm

Anastasy [175]

Here we need to convert 2. 1 cm to mm .

And for that we will use the following conversion .

1cm = 10 mm

So for 2.1 cm, we will multiply 2.1 and 10 to convert it to mm. Therefore 2.1 cm = 2.1* 10mm = 21mm

And that's the required answer .

What is the quotient of StartFraction 7 Superscript negative 1 Baseline Over 7 Superscript negative 2 Baseline EndFraction? Star

earnstyle [38]

The quotient of two expressions is the division of the expressions

The quotient of $\frac{7^{-1}}{7^{-2}}$ is 7

<h3>How to determine the quotient</h3>

The expression is given as:

$\frac{7^{-1}}{7^{-2}}$

Rewrite the above expression by applying the law of indices

$7^{-1 + 2$

Simplify the exponent

$7^{1$

Evaluate the exponent 7 raise to the power of 1

Hence, the quotient of $\frac{7^{-1}}{7^{-2}}$ is 7

The Country Buffet restaurant has tables that seat 6 people and booths that can seat 4 people. The restaurant has 38 seating uni

Alina [70]

Answer:

There are 20 booths and (38 - 20), or 18, tables

Step-by-step explanation:

Represent the number of tables with t and the number of booths with b.

We need to find the values of t and b.

(6 people/table)(t) + (4 people/booth)b = 188 (units are "people")

t + b = 38 (units are "seating units")

Solving the second equation for t, we get 38 - b = t.

Substitute 38 - b for t in the first equation:

(6 people/table)(38 - b) + (4 people/booth)b = 188

Then solve for b: 6(38) - 6b + 4b = 188, or:

228 - 2b = 188, or 2b = 228 - 188, or 2b = 40. Thus, b = 20 (booths)

There are 20 booths and (38 - 20), or 18, tables.
