When katie was born her mother invested $5000 in an account for her college savings. the interest rate is 3.5% compounded annually. to represent this, we can use the formula v = 5000(1 + r)t where r represents the interest rate and t represents the time in years. how much will katie have in her account when she turns 18? a) $5,175 b) $7,127 c) $9,287 d) $12,472

C is the answer, hope this helps.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
