Answer:
Yes, his collection will be complete by the time his grandfather visits
Step-by-step explanation:
Here, we want to know if his collection would be complete by the time his grandfather visits.
From the question;
he has collected 13 different quarters in 2.25 months
At the same rate, x different quarters will be collected in 9 months
Thus, mathematically;
x * 2.25 = 13 * 9
x = (13 * 9)/2.25 = 52
Thus, at this rate he would have collected 52 quarters in 9 months.
Since he has only 50 to collect, it means his collection would be complete by the time his grandfather visits
x-intercepts of parabola: y = 0
We have y = 2x² - 8x + 8
Answer: x-intercepts: x = 1 and x = 3.
Answer:
x = 8
Step-by-step explanation:
Since m and n are parallel lines, then
6x - 2 = 46 ← alternate angles
Add 2 to both sides
6x = 48 ( divide both sides by 6 )
x = 8
A Rectangle is a quadrilateral that has two sets of congruent sides.
(area of a rectangle, = base*height)
The fence (70m) consists of only 3 sides, two of which are congruent. Two factors of 600 equal the sum of the dimensions of the fence. Confused?
20 & 30 are factors of 600(area)
20+20+30=70(perimeter of fence only)
The garden, unlike the fence, includes the wall, which is equal to 30(the side that's missing it's congruent piece)
100=20+20+30+30, these are the dimensions of the garden.
We have to calculate the total weight of the three samples. After that we have to choose the correct answer. Weight of those three samples is: 0.170 grams, 0.204 grams and 2.300 grams. We simply have to find the sum of those weights: 0.170 g + 0.204 g + 2.300 g = 2.674 g. Answer: <span>C. 2.674 grams.</span>
