20 000 is as much as 20 * 1 000, so we can write it as: 20 * 10^3
3 400 000 is as much as 34 * 100 000, so we can write it as: 34 * 10^5
The sum in scientific notation would look like this:
20 * 10^3 + 34 * 10^5
I hope that's what you meant :)
Since ABC and DEF are similar then we can write:.
CB/FE = CA/FD
9/90 = b/360
b/360 = 1/10
b = 360/10
b = 36
Answer:
AB = 33.78228208
BD = 42.3
AT= 20.33068487
Area= 859.9879701
Step-by-step explanation:
Using the sin rule:
<u>sinA </u> = <u>sinB</u>
a b
If I use A = 90, a= 42.3
B = 53, b= AB
I get AB = 33.78228208 units
Then the diagonal is already 42.3 cm so I think. BD should be 42.3 cm too.
I used the sin rule again for ABD to find AD but by using B as 37° and b as AD.
I get AD = 25.45677548
For ADT,
AD is the hypotenuse.
Now I get from the same sin rule,
A= 90°. a= 25.45677548
B= 53°. b = AT
AT= 20.33068487 units.
Area of rectangle = l×b
= AB × AD
so that gives me 859.9879701 square units
Answer:
9/4
Step-by-step explanation:
0.25 is one fourth and if you convert the whole number into fourths and add the one fourth from the decimal it is 9/4
1. HI Because two parallel lines have to be on the same plane and never intersect.
2. Skew means the never intersect and they aren't on the same plane so it is GK and DH
3. Angle 3 corresponds because it is the bottom left and 7 is the bottom left.
4. 3 and 5 are same-side interior because they are both on the left side and both are inside.
Hope this helps!
