Answer:
Option D
0.6
Step-by-step explanation:
Given that there are 5 colour marbles in a large bag.
The colours are red, orange, yellow, blue and green.
Also given that there are equal amounts of each colour
Let n be the no of marbles of each colour.
Then total no of marbles = 5(n) = 5n
No of red,blue and yellow marbles = n+n+n = 3n
Prob of drawing a red or blue or yellow = P(red)+P(blue)+P(yellow)
=
= 0.60
Answer:
The polygons are similar
Explanation:
They both have the same proportions, just the one on the left is scaled down a bit.
Answer:
Step-by-step explanation:
What you gave 4x – y = 7 is in standard form
The problem on screen
4x-2/3y=7
The standard form is 12x-2y=21
Answer is A
Answer:
3 ; 4/3
Step-by-step explanation:
x + 4(1/x) = 13/3
x + 4/x = 13/3
x^2 -13/3x + 4 = 0
3x^2 - 13x + 12 = 0
Δ = 169 - 144 = 25
x1 = (13 + 5)/6 = 3
x2 = (13-5)/6 = 4/3
Answer:
1. x/2=1.75/3.5 x=1
2. 4/2=y/3.5 y=3.5
3. P (Figure Left)=3+5+2+1+4+8+3+2=28 cm
A (Figure Left)=8x2-2x1-3x2=8 cm2
4. P (Figure Left) / P (Figure Right) = 1/1.75 = 28/ P (Figure Right)
P (Figure Right)= 49 cm
A (Figure Left) / A (Figure Right) = 1/1.752 = 8/ A (Figure Right)
A(Figure Right)= 24.5 cm2
Step-by-step explanation:
1. x/2=1.75/3.5 x=1
2. 4/2=y/3.5 y=3.5
3. P (Figure Left)=3+5+2+1+4+8+3+2=28 cm
A (Figure Left)=8x2-2x1-3x2=8 cm2
4. P (Figure Left) / P (Figure Right) = 1/1.75 = 28/ P (Figure Right)
P (Figure Right)= 49 cm
A (Figure Left) / A (Figure Right) = 1/1.752 = 8/ A (Figure Right)
A(Figure Right)= 24.5 cm2
