Answer:
Step-by-step explanation:
The diameter is 70 ml
The radius is worth half the diameter, which means that the radius is 35 ml
A = pi r squared
A = 3.14 x 1225
A = 3846.45
3(2n-9) is the equation that is equivalent to 6n-27.
Answer:
y=mx+c
We have to find the value of m and c.
Let's substitute the value of x and y from the table.
When x=1, y=15,
15= m(1)+c
m +c= 15 ------(1)
Now substitute another set of x and y values.
When x=2, y=24,
24= m(2)+c
2m +c= 24
c= 24 -2m ------(2)
Let me rewrite the two equations so that it is clearer for you to see.
m + c= 15 -----(1)
c = 24 -2m -----(2)
subst. (2) into (1):
m+ 24-2m= 15
-m= 15-24 (bring constants to 1 side, m terms to the other)
-m= -9 (simplify)
m= 9 ( divide by -1 throughout)
subst. m=9 into (2):
c= 24 -2(9)
c= 24-18
c= 6
Thus, the equation is y=9x+6.
When the cat is 3 years old, x=3.
When x=3,
y= 9(3)+6
y= 33.
Hence, the cat is 33 years old in human years.
960 48*20=960, 48*21=1008
Answer: A and D are the correct statements.
1. In ΔBRS and ΔBDC
∠R=∠D and ∠S=∠C [∵ corresponding angles]
So by AA similarity criteria ,
△BCD is similar to △BSR.
2. As RS is parallel to DS then by basic proportionality theorem,
⇒ B is not true.
3. As we can see BC is greater than BS ,so it cannot possible.
If and
where BS=6 then .
4. As RS is parallel to DS then by basic proportionality theorem,
⇒BR×SC=RD×BS.
5. From 4 its not true that BR/RS = BS/SC.
