Answer:
135 inches
Step-by-step explanation:
A scale factor is the size of the object on paper.
So to get the actual size we must multiply by the reciprocal of the scale factor.
Dividing by 1/20 is the same as multiplying by 20.
Since the scale is 6.75 (I converted 3/4 to 0.75), we must multiply by 20 to get our original height.
So 6.75 * 20 = 135 inches
Answer:
25. If you look at angle B from the first figure you see a square that indicates a 90 degrees angle, thus the figure shown is a right triangle. You can also see that angle C is said to have 60 degrees. a right triangle has a total angle of 180 degrees. so, 180 - 90 - 60 = 30 degrees. Therefore, angle A is 30 degrees.
27. Now you want the measure of the hypotenuse, and you know this a right triangle. so, simply use the law of sines to find the measure of AC :
4cm/sin(60) = AC/Sin90
AC = 4.62 cm
29. angle z is in the other figure and same stuff, just substract the angles, you have 90 degrees and 30 degrees... 180 - 90 - 30 = 60 degrees
31. Angle Y = 90 degrees
this value is already given, it's the little square that indicates a 90 degrees angle.
26. 5 cm
28. 90 degrees
30. You already found AC, use the pythagorean theorem. sqrt((4.62)^2 - 4^2) = 2.31 cm
32. use pythagoras again, square root(5^2 - 3^2) = 4
So as you can see all the measurements are the same because if you see at the very top of your figures it says ABC = XYZ which means pretty much that they have the same values (notice that there is a little something added to the = sign, watch out for that because that's what indicates that two figures are equal in terms of angles and measures.
Answer:
7 hours=455 miles 6 hours=3
Step-by-step explanation:
FIrst, lets find how many mph he is at. 845/13= 65mph
So, if he goes for 7 hours, he would do 7*65, which is 455 miles
Then we can do 6*65 which is 390
Graphing the system of equations is shown in figure attached.
Solution set is (2,-4). The lines will intersect at (2,-4)
Step-by-step explanation:
We need to graph the system of equations. 
First we will find value of x and y
Let:
Add eq(1) and eq(2)
Putting value of x in eq(1) and finding y
So, y=-4

If you want to find out ..for example.. cube root of 8..just put it in the calculator!
Or you could power it by 1/3 ...which is the same thing as cube rooting it.
(Even though I need the calculator in both the cases..)
Hope this helps though :)
