A jar has 32 marbles. Some are blue and the rest are green. There are three times as many green marbles as blue. How many green marbles are in the jar
Answer: 24
Step-by-step explanation:
Number of marbles in jar = 32
Let blue marbles be represented by b.
Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b
We then add them together. This will be:
3b + b = 32
4b = 32
b = 32/4
b = 8
There are 8 blue marbles
Since green is 3× blue. Therefore,
Green = 8 × 3 = 24 marbles

You randomly draw A marble from a bag, record it’s color, and then replace it. You draw a blue marble 11 out of 50 times. What is the experimental probability that the next marble will be blue?
Answer:
since you recorded the first marble then replaced it, you drew 10 blue marbles, so therefore we can predict the next marble you drew, was blue.

Which is the best estimate of the distance between the point (-25, 10) and the origin?
O 8 units
w
O 15 units
O 23 units
O 27 units
The best estimate of distance between the point and the origin is 15 units. this is your answer.
The distance between the point (-25, 10) and the origin is 27units
Distance between two pointsThe formula for calculating the distance between two points is expressed as:
D = √x² + y² (since the other coordinate is an origin)
Given the coordinate points (-25, 10) and (0, 0)
Substitute
D = √(-25)² + 10²
D = √625 + 100
D = √725
D = 27unts
Hence the distance between the point (-25, 10) and the origin is 27units

310= -6.2f
I’m just struggling on this question;—;
Answer:
Step-by-step explanation:
sup. so what you're going to do is divide -6.2 on both sides to get f by itself
310/-6.2= -6.2f/-6.2
f=-50
Answer:
-50.
Step-by-step explanation:
310 = -6.2f
To solve for f we divide both sides of the equation by -6.2
310 / -6.2 = -6.2f / -6.2
f = -310/-6.2 = -50.
Change 8 1/2 to an
improper fraction.
Answer:
17/2
Step-by-step explanation:
Answer:
17/2
Step-by-step explanation:
Improper fraction means no whole number. So, we have to change 8 to a fraction with a common denominator as 1/2. So, 8/1 = 16/2, plus the given 1/2, that's 17/2.

Tiffany Is Filling Her Daughter's Pool With Water From A Hose. She Can Fill The Pool At A Rate Of 1/10 Gallons/Seconds. How Fast Can She Fill Up A 20 Gallon Pool
Answer:
200 seconds
Step-by-step explanation:
Given rate :
Filling rate = 1/10 gallons per second
How fast can a 20 gallon pool be filled ;
Time = size of pool / filling rate
Time = 20 gallons ÷ 1/10 gallon / second
Time = 20 * 10 / 1
Time = 200 seconds

An electrician charges $35 per hour, h, plus a $20 fee for driving to your house. Which equation represents to total cost, T, for the electrician to do a job?
Answer:
T= 20 + 35h
Step-by-step explanation:
Giving the following information:
An electrician charges $35 per hour, h, plus a $20 fee for driving to your house.
The $20 fee is a fixed cost. It will remain constant.
The $35 fee acts as a variable cost. It varies with the number of hours required to do the job.
To calculate the total cost (T), we need to use the following formula:
T= 20 + 35h
h= number of hours.
P(-,3) , Q(7,-3) and R (4,1) are three points. show that PQ=2QR using distance formula. (please show the steps too :)
Answer:
PQ is 10.
QR is 5.
Hence, PQ=2QR
Step-by-step explanation:
We have the three points P(-1, 3); Q(7, -3); and R(4, 1).
And we want to show that PQ=2QR.
In other words, we want to show that PQ/QR=2.
So, let's find PQ and QR. We will need to use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
To find PQ:
P is (-1, 3) and Q is (7, -3).
So, we will let P(-1, 3) be (x₁, y₁) and Q(7, -3) be (x₂, y₂).
Substitute the values into the distance formula. This yields:
[tex]d=\sqrt{(7-(-1))^2+(-3-3)^2[/tex]
Evaluate:
[tex]d=\sqrt{(8)^2+(-6)^2[/tex]
Evaluate:
[tex]d=\sqrt{64+36}=\sqrt{100}=10[/tex]
So, the distance of PQ is 10.
And to find QR:
Q is (7, -3) and R is (4, 1).
Again, we will let Q(7, -3) be (x₁, y₁) and R(4, 1) be (x₂, y₂).
Substitute appropriately. So:
[tex]d=\sqrt{(4-7)^2+(1-(-3))^2[/tex]
Evaluate:
[tex]d=\sqrt{(-3)^2+(4)^2[/tex]
Evaluate:
[tex]d=\sqrt{9+16}=\sqrt{25}=5[/tex]
So, the distance of QR is 5.
Therefore, it follows that:
[tex]\displaystyle PQ=2QR\Rightarrow \frac{PQ}{QR}=2\Rightarrow\frac{10}{5}\stackrel{\checmark}{=}2[/tex]
And we have shown that PQ=2QR.

A group of 5 friends decide to set up a lemonade stand. They sell 48 cups of lemonade for $1.35 each. If they split the amount of money they made evenly, how much does each friend take home?
Answer:
Step-by-step explanation:
There are a couple of ways you could do this. The first and most obvious way is just to find out what the total amount is and divide by 5
48 cups * $1.35 / cup = $64.80 total
Now divide by 5
$64.80 / 5 = 12.96 for each person.
The other way to do it is just to divide 1.35 by 5 = 0.27
Now multiply by 48 to get each person's share.
0.27 * 48 = 12.96
Take your pick. The answer is the same either way.

what is the mass of an object that weighs 7 kg and 50 N?
Answer:
7kg
Step-by-step explanation:
mass: amount of matter in a substance,
SI Unit: kg
It has nothing to do with N (weight) in this case so take the kg value as the mass
Answer:
0.71 kg
Step-by-step explanation:
a common equation in physics is w = mg
we can rearrange this to m = w/g
g is the acceleration of gravity: 9.81 m/s^2
w is the weight of the given equation of the object: 7 kg
so m = 7 kg ÷ 9.81 m/s^2
this gives us: m = 0.71 kg
