Any picture? Example: if the number is 36 you would round to 40 and if the number was 34 you would round to 30 if it is 35 you choose what to round to. It depends on the last digit.
3.7 x 4.1 x 10 = 151.7 cm2
Answer:
$2720
Step-by-step explanation:
Given data
Principal=$2000
r= %6
T= 6 years
The expression for the final amount is
A= P(1+rt)
A=2000(1+0.06*6)
A=2000(1+0.36)
A=2000*1.36
A=2720
Hence the amount is $2720
Answer:
The of tax is $ 2812.50
Step-by-step explanation:
Given that Mary's salary is $x per year, then applying the 15% flat tax rate will give the amount paid for tax as;
15/100 *x =0.15 x -----equation (i)
After reforms , Mary still pays a tax similar to the original system. This means the amount of Mary's salary is above $7500.
Mary's amount above is the flat rate of $7500 is ;
$(x-7500)
Applying the 25% tax will give;
25/100 ( x-7500)
0.25(x-7500)
0.25x -1875 --------equation (ii)
Equating the two equations
0.15x = 0.25x - 1875
collect like terms
1875=0.25x-0.15
1875 =0.10x
Divide both sides by 0.10 to get x
1875/0.10 = 0.10x/0.10
18750 = x
The amount of Mary's salary is $18750
The amount of tax she pays is;
0.15 * 18750 =$ 2812.50
Answer:
<u>The pattern is that the decimal point moves the same number of decimal points to the right as zeros the power of ten has.</u>
Step-by-step explanation:
To multiply a decimal number by a power of ten (such as 10, 100, 1,000, etc.), count the number of zero in the power of ten. Then go to the right the decimal point the same number of positions.
For example, 0.36 * 10 = 3.6. The multiplier 10 has one zero, so you move the decimal point in 0.36 one position to the right to get the product 3.6.
A second example, 0.36 * 100 = 36. The multiplier 100 has two zeros, so you move the decimal point in 0.36 two positions to the right to get the product 36.
<u>So, the pattern is that the decimal point moves the same number of decimal points to the right as zeros the power of ten has.</u>
