option 3
they are corresponding angles and are congruent
First you divide 1200 by 25 (1200/25) it comes out to 48.
That means the he types at a rate of 48wpm. So then all you have to do is multiply 48 and 45 and you get 2160 words.
In the first box is 2.
second box 1.
third 4.
fourth 5.
fifth 3.
Answer:
d = 0.7*t
Step-by-step explanation:
Given data,
Time Distance
10 7
15 10.5
20 14
From analysis,
1) d1/t1 = 7/10 = 0.7
2) d2/t2 = 15/20 = 0.7
3) d3/t3 = 14/20 = 0.7
It can be analysed from the figure that, at every point d/t = 0.7
Therefore, the relationship between t and d is
d = 0.7*t
or
t = d/0.7
Answer:
The coaster’s radius is 5 cm
Step-by-step explanation:
Drink Coaster has a circular shape.
Area of a circle = π*r²
so, area of the drink coaster = π x (Radius of the drink coaster)²
Given that Area of the drink coaster is 78.5 cm²
∴ 78.5 cm² = π*r²
Also we are to use 3.14 for π
∴ 78.5 cm² = 3.14*r²
r² = 78.5 cm² / 3.14
r² = 25 cm²
r =
cm
r = 5 cm
Hence, the coaster’s radius is 5 cm
