The height of a falling pinecone can be represented by y = -16° +64 where t is the time in seconds
and y is the height of the pinecone in feet. Write and solve an equation to find the number of seconds it
will take for the pinecone to reach the ground.
A. 4 seconds
B. 6 seconds
C. 2 seconds
D. 1.5 seconds
Answer:
4 Seconds
Step-by-step explanation:
Let's say the height of the ground is set at y = 0.
Then, since 16 times 4 is 64, we substitute 4 for x.
But wait! x is being squared!
So we need to find out what squared is 4. It's 2.
So, with x being equal to two, y is equal to 0.
But what is the number of seconds? We actually got it first.
That means that the answer is 4.
The pinecone takes 4 seconds to reach the ground.

Step-by-step explanation:
since 2 of the sides are much longer than the shorter sides, diagonals of a rectangle will not intersect at a right angle (perpendicular) whereas a square, with all sides equal, would. This is because the distance from the center to each of the corners is the same for each corner.
if 1/2p=2 1/2q, find q:p
its 2 and a half not 21/2
Answer:
1/5 = q/p, or q:p
Step-by-step explanation:
You might want to rewrite 1/2p=2 1/2q as (1/2)p = (2 1/2)q.
To remove the fractions, multiply both sides by 2:
p = 2(2 1/2)q becomes p = 5q.
Dividing both sides by 5 yields p/5 = q.
Dividing both sides by p yields 1/5 = q/p, or q:p
3) The start-up cost to join Tunes is $7.95 plus $0.95 per song downloaded. If Will spent $26, write and solve a linear equation to find how many songs he downloaded
Answer:
X = 19 songs
Step-by-step explanation:
Y = 0.95x + 7.95
26 = 0.95x + 7.95
Solve for x
26-7.95 =0.95x
18.05/0.95 = x
X = 19 songs

if the ratio of milk and water in 45 litre is 7:2. if 4 litre water is added what will be the new ratio.
Answer:
5 : 2
Step-by-step explanation:
sum the parts of the ratio, 7 + 2 = 9 parts
Divide the quantity by 9 to find the value of one part of the ratio
45 litres ÷ 9 = 5 litres ← value of 1 part of the ratio , then
7 parts = 7 × 5 = 35 litres
2 parts = 2 × 5 = 10 litres
In 45 litres there is 35 litres of milk and 10 litres of water
Adding 4 litres of water gives
35 : 14 = 5 : 2
200 tickets were sold in a school’s annual musical performance. Students' tickets cost $2.50 each and parents tickets cost $3.50 each. The total amount collected was $537. How many tickets were sold for parents?
Answer:
Step-by-step explanation:
number of students ticket sold = x
number of parent tickets sold = y
If a total of 96 tickets were sold
x+ y =96 ---- eq 1
If a total of 96 tickets were sold for $306.25
2.50x + 3.75y=306.25 ---- eq 2
x+ y =96
y=96-x
substitute value of y in equation 2
2.50x + 3.75 (96-x)=306.25
2.50x + 360 -3.75x =306.25
- 1.25 x = -53.75
x = 43
therefore the answer would be y=96-x=96-43=53

We have two fractions, \dfrac{2}{5} 5 2 start fraction, 2, divided by, 5, end fraction and \dfrac{3}{10} 10 3 start fraction, 3, divided by, 10, end fraction, and we want to rewrite them so that they have a common denominator (and whole number numerators). What numbers could we use for the denominator? Choose 2 answers: Choose 2 answers: (Choice A) A 10 (Choice B) B 5 (Choice C) C 20 (Choice D) D 15
Answer:
(Choice A) A 10
(Choice C) C 20
Step-by-step explanation:
Fraction 1: 2/5
Fraction 2: 3/10
rewrite them so that they have a common denominator (and whole number numerators
For both fractions to have a common denominator, find the lowest common multiple of both denominators
5 = 5, 10, 15, 20, 25, 30, 35, 40
10 = 10, 20, 30, 40
The two lowest common multiple of 5 an 10 is 10 and 20

A mother bear and her cub catch fish from a river . The mother bear catch 10 fish the mother bear catch 5 times as many
Answer:
This doesn't make sense.
Step-by-step explanation:
If the question was "A mother bear and her cub catch fish from a river. The cub catches 10 fish and the mother bear catches 5 times as many as the cub. How many fish did the cub catch?" then the answer would be, The mother bear caught 50 fish.
This is because if the cub caught 10, and the mother caught 5 times that amount, the mother caught 5 x 10 fish. 5 x 10 = 50.
