Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.
Step-by-step explanation:
Let,
Weight of one large bead = x
Weight of one small bead = y
According to given statement;
12x+8y=88 Eqn 1
5x+2y=25 Eqn 2
Multiplying Eqn 2 by 4
Subtracting Eqn 1 from Eqn 3
Dividing both sides by 8
Putting x=1.5 in Eqn 1
Dividing both sides by 8
Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.

Answer:
THE INCREASE AND DECLINE OF POPULATION
Step-by-step explanation:
Up until the beginning of the industrial revolution, global population grew very slowly. ... After about 1800 the growth rate accelerated to a peak of 2.1% annually in 1968; but since then, due to the world-wide collapse of the total fertility rate, it has declined to 1.1% today (2020).
Over which interval(s) is the function decreasing?
Circumference of a circle is the distance around the circle. This can be found by using the equation below
2*pi*radius
Our diameter, as shown, is 9cm. Since radius is half of the diameter, our radius is 4.5cm.
Therefore, our circumference is...
2 * pi * 4.5 = 9pi cm total
Answer:
B, $1.32
Step-by-step explanation:
100 grams is 0.1 kilograms, and 25 grams is 0.025 kilograms. The difference is 0.075 kilograms. At $17.60 per kilogram, 0.075 kilograms would cost $1.32 or answer choice B.
