Answer:
152£
Step-by-step explanation:
1. 1/3 of the coins is 255/3=85 85coins is worth 1£
2. 110 of the coins are worth 50p
3. to figure out hos many 20p coins
total number of coins - number of 1£ coins - number of 50p coins
255-85-110=60
60 of the coins are worth 20p
4 add everything togheter
85£ from first
110/2=55£ from second
60 coins are worth 20p
5 coins make 1£
60/5=12£
5. add everything 85+55+12=152£
Answer:
Move the center of circle A to (1,7), then multiply its radius by 3.
Step-by-step explanation:
Moving the circles to the same center would make them concentric. Then, by multiplying the radius of Circle A by 3, the circle is dilated to the exact size of circle B, since its radius is 9. This shows that Circle B is proportional to Circle A, thus they are similar.
We are given the series of <span>a1 = -5 a2 = 20 a3 = -80. In this case, we can see that this is a geometric sequence with a geometric ratio equal to 20/-5 = -80/ 20 or equal to 4. Hence, r is equal to 4, a1 is equal to -5.
The geometric sequence formula is an = a1*r^(n-1) = -5 * (-4)^ (n-1) where n is an integer. Answer is B.</span>
Set Lauren's age equal to L.
Using what the problem gave us, we can quickly set up an equation:
5L - 2 = 2L
Solving this equation, we get 3L = 2. L = 2/3 Lauren is 2/3 of a year old.
