Answer:

If we only use tenths, then we wont be able to model the hundredths place value that is the value of 4 in the given decimal.

Step-by-step explanation:

We are given the number 6.84

The place value chart for this number can be written as:

Place value:        Ones  .  Tenths  Hundredths

          6.84:             6     .       8               4

The decimal expansion can be written as:

6.84 = 6\times 1 + 8\times \displaystyle\frac{1}{10} + 4\times \displaystyle\frac{1}{100}

If we only use tenths, then we wont be able to model the hundredths place value that is the value of 4 in the given decimal.

To model 4 that is 0.04, we need

\displaystyle\frac{1}{10}\times \displaystyle\frac{1}{10}\times 4 = 0.04

To model 6, we need

10\times \displaystyle\frac{1}{10}\times 6 = 6

Consider circle H with a 3 centimeter radius. If the length of minor arc RT is 2 3 π, what is the measure of ∠RST?
Nataliya [291]
The main formula is   arc RT =  r x measure <span>RST
so </span>∠RST=<span>minor arc RT / r
 </span>minor arc RT = 23<span>π
r= 3 cm 
</span>∠RST= 23<span>π/3</span>

Julie cashed a paycheck and repaired her brother $10 that she borrowed from him. She then spent $30 on fuel for her car and half
pochemuha
Remark
She starts out with x
She spends 10 dollars paying back her brother (that's - 10)
She spends 30 dollars on fuel (that - 30)
She spends 1/2 what's left on a tent ( that's 1/2 (x - 10 - 30) )
She then spent 29.45  on running shoes. 1/2 (x - 10 - 30) + 29.45 is her expenditures.

After all that she has 17.75 left. 

Equation
x - 10 - 30 - 1/2(x - 10 - 30) - 29.45 = 17.75   

Solve
Begin by adding 29.95 to both sides. 
x - 10 - 30 - 1/2(x - 10 - 30)  = 17.75 + 29.45 
x -10 - 30 - 1/2(x - 10 - 30)  = 47.20  Add the like terms on the left.
x - 40 - 1/2(x - 40) = 47.20 Add 40 to both sides. Don't go inside the brackets.
x - 1/2x + 1/2 (40) = 87.20
1/2 x + 20 = 87.20                        Subtract 20 from both sides.
1/2 x = 67.20                                Multiply by 2
x = 134.40
