Answer:
107810
Step-by-step explanation:
You can use the order of operations! So we start with 99^3/9. That is 99^2*11. So now let’s do 99/99, it’s 1. So 99^2*11 is 107811, so the answer is 107810.
Answer:
Distance xy is 6
Distance yz is 11
Step-by-step explanation:
Given that the full length between x and z, xz = 17
Point y is located along xz where :
yz = 3x-10
xy = 2x-8
A simple sketch to show the distance and points can be;
x----2x-8---------y------3x-10-----------z
-----------------------17-----------------------
So you can see from this sketch that;
(2x-8) +(3x-10) = 17
2x-8+3x-10=17
5x-18=17
5x=17+18
5x=35
x=35/5 = 7
x=7
Distance xy=2x-8 = 2(7)-8 = 14-8 = 6
Distance yz=3x-10 = 3(7)-10 = 21-10 =11
The number of significant figures in the numbers are
- 100 cm = 1 significant digit
- 0.006700 cm = 2 significant digits
- 450. cm = 3 significant digits
<h3>How to determine the number of significant figures in the following numbers?</h3>
As a general rule, the zeros before and after the non-zero figures are not significant.
Using the above rule, we have:
- 100 cm = 1 significant digit
- 0.006700 cm = 2 significant digits
- 450. cm = 3 significant digits
<h3>
How to round the following numbers to the correct number of significant figures</h3>
Using the above rule in (a), we have:
- 123g to show 1 sig fig = 100 g
- 0.19851m to show 2 sig figs = 0.2 m
- 0.0057034L to show 3 sig figs = 0.005703 L
<h3>How to report the following answers with correct significant figures</h3>
We have:
(12.93cm) x (2.34cm) x (8cm) = 242.05 cm^3 because 12.93 has 4 significant figures
67.0m / 2.18s = 30.7 m/s because 2.18 has 3 significant figures
<h3>How to convert the following metric to metric</h3>
450mL = 0.45 L
because 1 mL = 0.001 L
2.3 dm = 0.00023 km
because 1 dm = 0.0001 km
0.120cg = 1.2 mg
because 1 cg = 10 mg
6700L = 670000 cL
because 1 L = 100 cL
<h3>How to convert the following metric</h3>
a. 2.34miles = 3.76 km (1mile = 1.61km) -- given
b. 5.3ft = 161.544 cm(2.54cm = 1 in)
Because 1 ft = 30.48 cm

Answer:
y+6=9(x+4)
Step-by-step explanation:
point slope form is y-y1=m(X-x1)
y1 is -6
x1 is -4
And the slope or m is 9 so we can fill it in
y-(-6)=9(x-(-4))
y+6=9(x+4)
we can fill the equation out to see if it’s true
-6+6=9(-4+4)
0=9(0)
0=0
It is true
