Answer:

First one: 40%

Second one: 30%

Step-by-step explanation:

2/5 is equal to the fraction 4/10 which is also equivalent to 40/100

in a percentage that would be 40% of the dogs are poodles

to find a percentage divide numerator by demonimator and multiply by 100

so divide 12 by 40 and multiply by 100

12/40=0.3

0.4x100=30%

For what values of x does 25× - 5×²-3?

dusya [7]

Answer:

X = 3, -1; B

Step-by-step explanation:

Use log properties, log 5 on both sides, log 5 of 25 is 2 that times the exponent, so 2*x = 2x, and on the other side, log 5 and base of 5 cancels. So 2x = x^2 -3, which can be solved using factoring:

x^2 -2x -3 = (x-3)(x+1) = 0, x=3,-1

On her birthday, Sonia distributed chocolates in an orphanage. She gave 5 chocolates to each child and 20 chocolates to adults.

qwelly [4]

Answer with explanation:

Total number of Children = x Children

Total number of chocolates distributed = y Chocolates

If there are x children, then total number of chocolate got by children= 5 x Chocolate

Number of chocolate got by Adults= 20

Let total number of adults be z.

Expressing the statement in terms of Equation

y = 5 x + 20 z

$z=\frac{y-5 x}{20}$

⇒Number of Adults =z

$=\frac{y-5 x}{20}$
