What are the significant digits in the number 12080

1 answer:

4 0

There are a few rules to significant figures. The first is that any non-zero digits count as significant figures, so 1, 2 and 8 are significant figures. Now we have 3 significant figures so far.
<span>
(significant figure = sigfig = sf)

There are a few cases in which zero can count as a significant figure. If it is between two non-zero digits, like in 405 (3 sig fig) or in 6074 ( 4 sig fig), so the zero between the 2 and the 8 counts as a significant figure, raising the total of significant figures up to four.

Another case is when a zero is added on the end of a decimal, like in the example 2 (1sf) versus 2.0 (2sf) This is essentially the same as 2, but has 0 added on the end, after the decimal. This zero counts as a significant figure. 12080 has no decimal point, so this does not matter in this example.

The total number of significant figures is 4.</span>

Volume is defined as area of the base*the hight.

In this question the base is the traingles.

Area of a triangle is base*hight/2, so it 8*6/2= 24

Volume is 24*8(hight)=192

So the answer is 192cm^3

Answer:

Step-by-step explanation:

A. Calculating The Markdown Price

X=Markdown price

Original price: $600

Markdown rate: 20%

100%-20%=80%

The TV's price is now 80% of what it originally was.

$\frac{x}{600} =\frac{80}{100\\}$

100x=48000

x=480

The price of the TV after being marked down is $480.

B. Calculating The Sales Tax

Y=Total sales tax

TV price: $480

Sales tax: 10% or 0.1

y=480*0.1

y=48

The total sales tax is $48

C. Calculating Your Total

x+y=total

480+48=total

total=528

You in total pay $528 for the TV.

A trust fund worth $25,000 is invested in two different portfolios, this year, one portfolio is expected to earn 5.25% interest

OLEGan [10]

Answer:

The amount of money that should be invested at the rate of 5.25% is $12,000 and the amount money that should be invested at the rate of 4% is $13,000

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

Let

x ------> the amount of money that should be invested at the rate of 5.25%

25,000-x -----> the amount money that should be invested at the rate of 4%

in this problem we have

$t=1\ year\\ P_1=\$x\\P_2=\$(25,000-x)\\r_1=0.0525\\r_2=0.04\\I=\$1,150$

substitute in the formula above

$I=P_1(r_1t)+P_2(r_2t)$

$1,150=x(0.0525*1)+(25,000-x)(0.04*1)$

Solve for x

$1,150=0.0525x+1,000-0.04x$

$0.0525x-0.04x=1,150-1,000$

$0.0125x=150$

$x=\$12,000$

$|$25,000-x=\$13,000$

therefore

The amount of money that should be invested at the rate of 5.25% is $12,000 and the amount money that should be invested at the rate of 4% is $13,000

Answer:

x = 10

Step-by-step explanation:

X = 10 because if you look at the 28 and 14, 14 is half of 28 so the ratio is 1:2 which would also work for the 20 so the answer is 10
