Answer:
24 units
Step-by-step explanation:
Given is a circle with two chord BE and CD
BE and CD intersect at A
By circle chords intersection theorem we have
DA*AC = EA*AB
i.e. 8(15) = 5(AB)
Divide by 5 both the sides
AB =8(15)/5 = 8(3) = 24 units
Verify:
Let us check now whether chord intersection theorem is satisfied.
DA*AC = 8(15) = 120
EA*AB = 5(24) = 120
Since these two equal, we verify that answer is right.
Answer:
They are 7 and 11. 11 + 7 = 18, 11 - 7 = 4.
Answer:
40:80
Step-by-step explanation:
x+2x=3x
3x=120
120/3=
40
40*2=80
40:80=1:2
Answer:
D. 3*10^2
Step-by-step explanation:
Given the diameter of human red blood cell = 0.000009 m
diameter of a cold virus = 0.00000003 m
To know how many times as large is the diameter of a red blood cell as the diameter of a cold virus, we will take the ratio of the diameter of human red blood cell to that of a cold virus as shown;
diameter of human red blood cell/diameter of a cold virus = 0.000009 m/0.00000003 m
= 9*10^-6/3*10^-8
= 9/3 * 10^-6-(-8)
= 3 * 10^(-6+8)
= 3*10^2
Hence the diameter of a red blood cell is 3*10^2 larger than that of the cold virus
Answer:
1944 in³
Step-by-step explanation:
We are given;
Dimensions of a triangular prism;
- Base is 18 inches
- Length is 9 inches, and
- Length is 24 inches
We are required to determine the volume of the prism
To answer the question we need to know that the volume of a triangular prism is given by;
Volume = 0.5 × Width × height × Length
Therefore;
Volume = 0.5 × 18 in × 9 in × 24 in
= 1944 in³
Thus, the volume of the triangular prism is 1944 in³
