Does it say how many of the marbles in the bag are red? Normally you will want to divide the amount of red marbles to the amount total marbles and you will get a percent. It's also note worthy that it states the marble going back into the bag. It would change if it was left out still.

Answer:
x=5
Step-by-step explanation:
please help me please
Answer:
x = - 5
Step-by-step explanation:
Remember that f(x) is the same value as y. So if f(x) = 1 then y = 1
There is only 1 point that has a y value of 1 and it is on the far left. The value you want is - 5
The answer is x = - 5 when f(x) = 1
what is 10^4 divided by 10^19 =?
Answer:
1e-16
Step-by-step explanation:
(10^4)/(10^19) =
(10*10*10*10)/(10^19)=
(1,000)/(10^19) =
1,000/(10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10)=
1,000/(10,000,000,000,000,000,000) =
1,000/10,000,000,000,000,000,000 =
1e-16

Answer:
John's ball hit the court first
Step-by-step explanation:
to solve for who hit the court first we have to look for when x was 0
John's ball hit the court in 1 second
now to look for the other guy we substitute 0 to the equation
0 = (-16t - 2) (t - 2)
we cannot substitute 0 to t because its looking for when it hit the court. x is 0 because it hits the ground
soo i guess we distribute ?
or actually we equate both to 0 i think
-16t - 2 = 0 t - 2 = 0
-16t = 2. t = 2
t = 2/-16
t = 1/-8 t = 2
theres two answers but 1/-8 is wrong because theres no such thing as the ball going underground (LOL) so his ball hit the court two seconds later
John's ball hit the court first i think
im not sure how to do the rest, but i do know how to do the first. Sorry but hope this helps you a little!

Which of the following statements is NOT a property of parallelograms?
All 4 angles are congruent.
Opposite angles are congruent.
Opposite sides are congruent
Parallelograms have 4 straight sides.
Step-by-step explanation:
Parallelogram is a quadrilateral s.t. opposite sides are parallel.
1. 4 angles DON'T necessarily have to be congruent
2. True
3. Opp. sides DON'T necessarily have to be congruent
4. True
SO first and third statements are NOT property of parallelogram
Molly bought 4.25 pounds of fish for $10.20. What is her unit rate (cost per pound)?
Answer:
$2.40 per pound
Step-by-step explanation:
Take the cost and divide by the pounds
$10.20/ 4.25 pounds
$2.40 per pound
Answer: The answer is 2.4
To find out the cost per pound, you just have to divide. For example, in this problem, you would divide 10.20 by 4.25 to see how much money it is for one pound of fish
For each of the bookcases a woodworker is building, she
charges $65 for materials. She also charges $35 for each
hour she works to build the bookcases. How much does
the woodworker charge for working 100 hours to build 18
bookcases?
A$4,735
B$3,565
C$3,583
D $4,670
35x100 hours = $3500+$65= $3565 for 100 hours of work and materials.

A bacteriologist estimates that there are 5.2×10^4 bacteria growing in each of 20 petri dishes. About how many bacteria in total are growing in the petri dishes? Express your answer in scientific notation
Answer:
1X10^6
or
1.04x10^6
Step-by-step explanation:
You start by multiplying 5.2x10^4 by 20 because there are 20 petri dishes with this amount growing, and you get 1,040,000. Now we need to convert it to scientific notation. We know that 1,000,000 is 10^6, so we would move the decimal to the left 6 places and get 1.04x10^6. This is in scientific notation, but we need to keep in mind significant figures (sig figs), so your final answer would be 1x10^6, if that is not what your instructor is looking for, try 1.04x10^6.

if investment double every 7 years and you start with 600$ investment how much money would you have after 21 years
Answer:
$29,400
Step-by-step explanation:
21 years divided by 7 years = 3, which means we can separate this into 3 categories
$600 for 7 years is 4200
$1200 for 7 years is 8400
$2400 for 7 years is 16800
add the answers together
4200 + 8400 + 16800 = 29400

Answer:
p = 6, q = - 1
Step-by-step explanation:
Using the rules of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , [tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]
Given
xy = 32 , tat is
[tex]2^{p}[/tex] × [tex]2^{q}[/tex] = [tex]2^{5}[/tex]
Since the bases on both sides are equal, equate the exponents
p + q = 5 → (1)
Also
2xy² = 32 ( divide both sides by 2 )
xy² = 16 , that is
[tex]2^{p}[/tex] × [tex](2^{q}) ^{2}[/tex] = 16
[tex]2^{p}[/tex] × [tex]2^{2q}[/tex] = [tex]2^{4}[/tex] , then p + 2q = 4 → (2)
Thus
p + q = 5 → (1)
p + 2q = 4 → (2)
Subtract (1) from (2) term by term
q = - 1
Substitute q = - 1 into (1) for corresponding value of p
p - 1 = 5 ( add 1 to both sides )
p = 6
What the answer to PTR?
Answer:
∠ PTR = 140°
Step-by-step explanation:
∠ PTQ and ∠ RTS are vertical and congruent, thus
2x + 16 = x + 28 ( subtract x from both sides )
x + 16 = 28 ( subtract 16 from both sides
x = 12
Thus ∠PTQ = x + 28 = 12 + 28 = 40°
∠ PTQ and ∠ PTR are adjacent and supplementary, thus
∠ PTR = 180° - 40° = 140°
