Answer:
11%
Step-by-step explanation:
We need to fill the missing cells of the table first and are interested in first row for under age 15
1. 152- 65= 87 for the top left cell
2. 165- (87+60)= 18 for car column on same row
now we have number 18 and the total of the first row is 165:
So the first choice- 11% is the answer
Step-by-step explanation:
this creates 2 similar triangles.
that means all angles are the same. and all the side lengths of one triangle correlate to the corresponding side lengths of the other triangle by the same multiplication factor.
her shadow is 23.05 - 18.9 = 4.15 m long.
the factor between the shadow lengths is then
4.15 × f = 23.05
f = 23.05 / 4.15 = 5.554216867...
the same factor now applies to the relation of the heights :
1.45 × 5.554216867... = 8.053614458... m
rounded the tree is 8.05 m tall.
AK = 640
Δ ABC and ΔFJK are similar. They are small triangles.
ΔCDF is the big triangle.
640 / 2 = 320 m= CF
AC & FK= 320/2 = 160 m each
2AC = CF = 2FK
2(160) = 320 = 2(160)
BG = 20 m
20/160 = x / 320
20*320 = 160x
6400 = 160x
6400/160 = x
40 = x
Area of CDF = (40 m * 320 m)/2 = 12,800 / 2= 6,400 m²
Answer:
p(7,-11)
that is the answer of the coordinates
Answer:
27 years
Step-by-step explanation:
21 × 2 = 42
42 - 15 = 27
