Answer:
1. The scale factor here is 1.5
2. The scale factor here is 2/3
Step-by-step explanation:
Here, we shall be dealing with scales of triangles.
we have two triangles;
ABC and DEF
longest sides are in the ratio;
12 : 8
1. What scale factor translates DEF to ABC?
The ratio of the length can be beaten down to 3:2
So therefore, we can see that by multiplying the sides of of DEF by 1.5, we can arrive at the sides of ABC
So the scale factor here is 1.5
2. This is like the other way round of what we have above.
By multiplying the sides of ABC by 2/3, we shall have the sides of DEF
Answer:
(2,1)
Step-by-step explanation:
Because it rises by 2 and runs by 1
Answer:
$3.4875
Step-by-step explanation:
AS the ride is completed and according the rule the person have to give a tip on the total taxi ride
according to the given
tip given 15%
Total ride cost = $23.25
To find is the total tip given in dollars
Solution:
Total tip in dollars = 15 % of total ride cost
Putting the values of the given
Total tip in dollars = 15 % of 23.25
it can be written as
= 
=
=$ 3.4875
So the total tip would be $3.4875
Answer:
5 : 30
Step-by-step explanation:
Note that
× 10 = 5
Thus 3 × 10 = 30
Hence
: 3 = 5 : 30
Answer:
height = 11.5 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A =
h(a + b)
where h is the height and a, b the bases
here a = 21, b = 8 and A = 166.75, hence
h(21 + 8) = 166.75
Multiply both sides by 2 to eliminate the fraction
29h = 333.5 ( divide both sides by 29 )
h = 11.5 in
