how many significant digits are in the number 129,000,000,000 m?
Answer:
3
Step-by-step explanation:
There are 3 because only numbers with values higher than 0 are counted, unless there is a decimal.
Becuase there is no decimal at the end of this number, there are only 3 counted. Those counted are 1 2 and 9, and all of the 0s dont count.
If there was a decimal at the end this number, it would have been 12

Write the null and alternative hypothesis which would pertain to a hypothesis test described in each scenario last year politicians average 2000 trouble hours this year with an election occurring it is expected that they will travel more hours
Considering the situation given, it is found that:
The null hypothesis is [tex]H_0: \mu = 2000[/tex]The alternative hypothesis is: [tex]H_1: \mu > 2000[/tex].At the null hypothesis, we test if they average the same amount of trouble hours as last year, that is, of 2000 trouble hours, thus:
[tex]H_0: \mu = 2000[/tex]
At the alternative hypothesis, we test if this amount has increased, that is:
[tex]H_1: \mu > 2000[/tex]

Answer:
a. 53.68
b. 53.53
Step-by-step explanation:
a. Step 1: Approximate the value for [tex]\sqrt{62}[/tex]:
Since [tex]\sqrt{62}[/tex] is close to [tex]\sqrt{64}[/tex] (which is 8), this value can be approximated as a number that is less than but very close to 8. I chose 7.9.
The expression becomes 6(7.9)+2π
Step 2: Approximate the value for 2π
Since π is approximately 3.14, 2π is approximately 6.28.
The expression becomes 6(7.9)+6.28
Step 3: Use order of operations
6(7.9)+6.28=47.4+6.28=53.68
b. Step 4: If allowed, use a calculator to check how close your approximation is to the actual value
[tex]6\sqrt{62} +2\pi =53.5272[/tex]
The approximation 53.68 is decently close to the actual value, so no minor math errors were made.
Answer:
54 and 53.53 see below
Step-by-step explanation:
Estimate the square root first. 7x7 = 49 and 8x8=64 so you can use 8 for your estimate. You can also estimate Pi as 3.
Now you have:
(6 x 8) + 2(3) which is 48 + 6 = 54
Using your calculator you get
47.244 + 6.283 = 53.53 rounded to the nearest hundredth

If the room is a 14 by 12' rectangle then the strip of wallpaper needs to be at least how long?
Answer:
52 ft.
Step-by-step explanation:
In this case, we need to calculate a perimeter, which is the sum of all sides of the rectangle.
So, rectangles has opposite sides equal, therefore, the perimeter should be:
; having L as the larger side.
Hence, the strip of wallpaper needs to be as least 52 ft.

Step-by-step explanation:
Basically, let's represent the amount of money earned in
July with x
and
August with x+90
x+(x+90)=350
2x+90=350
2x=350-90
2x=260
x=260÷2
x=130
So, Wanda earned $130 babysitting in July and in July, 130+90=$220.

A car increased price by 3/4. after the increase it was priced at £84 what was the original price???
Answer: I think this is how we do it but i am not sure the answer is 48
Step-by-step explanation:
if the price increase by 3/4 then that mean it total will be 7/4 as 4/4 is it original price add so 7/4=84/x 84x4 is 336 336 divide by 7 is 48 to check 48 x 7/4 or 48 x 3/4 and add 48 if u math is correct than u should get 84

$400 at 6.3% for 4 years. Find the simple interest
Answer:
the amount of interest is $100.80
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6.3%/100 = 0.063 per year,
then, solving our equation
I = 400 × 0.063 × 4 = 100.8
I = $ 100.80
The simple interest accumulated
on a principal of $ 400.00
at a rate of 6.3% per year
for 4 years is $ 100.80.

Nick has two pet rabbits. He's Flemish giant rabbit weighs 5 times as much as his Holland lop rabbit.
If Nick's Flemish giant rabbit weighs 11 more pounds than he's Holland lop rabbit, how much does his Flemish giant rabbit weigh?
Taking into account the definition of a system of linear equations, the weigh of Flemish giant rabbit is 13.75 pounds.
System of linear equationsA system of linear equations is a set of two or more first degree equations, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, a solution to a system of two or more linear equations is a solution that simultaneously satisfies all the equations in the system
Flemish giant rabbit weighIn this case, a system of linear equations must be proposed taking into account that:
"f" is the Flemish giant rabbit weigh."h" is the Holland lop rabbit weigh.You know:
Flemish giant rabbit weighs 5 times as much as his Holland lop rabbit.Nick's Flemish giant rabbit weighs 11 more pounds than he's Holland lop rabbit.The system of equations to be solved is
f= 5×h
f= h +11
There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, substituting the first equation in the second you get:
5×h= h + 11
Solving:
5×h- h= 11
4×h= 11
h= 11÷ 4
h= 2.75
Substituting this value in the first equation of the system of equations:
f= 5×2.75
f= 13.75
Finally, Flemish giant rabbit weighs 13.75 pounds.
