Step-by-step explanation: 5pi converts to 15.70796
Answer:
slightly less than 15 of b.
A) Find the 15th term of a linear sequence (AP) whose 5th term is 30 and 20th term is
75.
B) The second and the fourth terms of an exponential sequence (GP) of positive terms
are 9 and 4 respectively. Find
D) The common ratio;
i) The first term
2. Solve for x and y in the following equations: 2(x+4y) = 1.22+8y
Answer:
A) 60
B) Common ratio, r, = 2/3
The first term, a, = 13.5
Step-by-step explanation:
A)
The formula for the nth term of a linear sequence is an+b. So we can say:
30=5a+b
75=20a+b
which means
b=30-5a
b=75-20a
30-5a=75-20a
15a=45
a=3
30=5(3)+b
b=30-15=15
So our formula is 3n+15. Sub in 15 for n to find the 15th term: 3(15)+15=45+15=69
B)
The formula for the nth term of an exponential sequence is arⁿ⁻¹, where a is the first term of the sequence and r is the common ratio. Therefore we can say: 9=ar, and 4=ar³, which means a=9/r and a=4/r³
9/r=4/r³
9r³=4r
9r²=4
r=√(4/9)=2/3
9=a(2/3)
a=27/2=13.5

Answer:
10.4 cm
Step-by-step explanation:
Since the area is half of the base multiplied by the height A = 1/2 * b * h, the height can be found from h = 2A/b
h = (2 * 83.72 )/16.1 = 10.4
Answer:26.02
Step-by-step explanation:83.72-(16.1x2)/2=26.02 (sry I know it’s confusing but that’s how I do math lol) brainlyest plz plz I need it for my rank

Active ingredient of a pill comprises 45% of the pill mass. If a pill contains 325 mg of active ingredient,
what the total mass of the pill?
Answer:
Step-by-step explanation:
The idea here is to be able to write and then solve the equation needed for this. In words, this is what you are looking to solve: "The active ingredinet is 45% of the mass of the pill". Putting those words into an equation:
active ingredient = .45 (mass of pill). Since our active ingredient is 35 mg:
325 = .45m and divide by .45:
m = 722.2 mg
If a normal 6 sided die, with each side numbered 1 through 6, is rolled. What is the probability that the number on top is greater than 3?
Select one:
1/6
1/2
1/3
2/3
Answer: the second option (1/2)
Step-by-step explanation:
numbers greater than 3: 4, 5, and 6
3 numbers
so 3/6 or 1/2
1/2 or 50% so the second option

Joe, working alone, takes 8 hours to mow a lawn. Sally, working alone, can mow the same lawn in 6 hours. How long does it take them together to mow the lawn (each using their own seperate mower)?
Answer: 3 3/7 hours
Step-by-step explanation:
you need to find out how much work they can do in an hour.
let x represent the total collaborative work
1/8 + 1/6 = 1/x
3/24 + 4/24 = 1/x
7x = 24
x = 24/7 or 3 3/7 hours (in decimal form this is 3.4286)
I cannot guarantee this is correct but hope it helped
Mr. Ortiz's car drives 12 miles in 20 minutes. Use a model to find out how many miles his car drives in 1 HOUR.
Answer:
36 miles
Step-by-step explanation:
Since there are 60 minutes in a hour, you can see that 20 minutes is a third of that time. To find the answer, you multiply the values by 3 to equal on hour. 20x3 = 60 and 12x3 = 36, meaning he drove 36 miles in a hour.
Suppose you have a bag containing 5 white marbles, 8 black marbles, 4 red marbles, and 9 green marbles. You draw a
single marble, record the color, and then place the marble back into the bag. You do this 10 times in total. After the final
time, you count your observations and see that you drew a black marble 3 times. Using what you know about theoretical
probabilities, was this likely to occur? Explain.

Circle O is centered on the origin with a diameter of 14 units. Determine if the point
reasoning
(-3,2/10)
is on the circle. Explain your reasoning
Answer:
Circle centered on origin, (0, 0)
Radius = 7units
To find if the point lies on the circle , check if the distance from the center to the point is 7units.
[tex]distance = \sqrt{(x_{1} -x_{2})^{2} +(y_{1} -y_{2})^{2} } \\(x_{1} ,y_{1} ) =(0, 0)\\(x_{2}, y_{2}) = (-3, 2\sqrt{10} )\\\\distance = \sqrt{(0--3)^2+(0-2\sqrt{10})^2 } = \sqrt{9+40} = \sqrt{49} = 7units[/tex]
Since the distance between the center and the point is 7units. the point lies on the circle.
Circle O is centered on the origin with a diameter of 14 units. Since the distance between the center and the point is 7units. So, the point lies in the circle.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]
We have been given a Circle centered on the origin, (0, 0)
Radius = 7units
In order to find if the point lies on the circle, check if the distance from the center to the point is 7units.
(x, y) = (0, 0)
(p, q) = (-3,2√10)
[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]
[tex]D = \sqrt{(0-(-3))^2 + (0-2\sqrt{10} )^2} \: \rm units.\\\\D = \sqrt{9+ 40} \\\\D = \sqrt{49} \\\\D = 7[/tex]
Since the distance between the center and the point is 7units. So, the point lies on the circle.

Putting soil is sold in bags that contain 1/2 cubic foot of soil. Estimate how many bags Rylee should buy.
9514 1404 393
Answer:
11 bags
Step-by-step explanation:
12. As you noted in problem 11, the volume needed to fill the three pots is 5.05 cubic feet. The number of bags needed is ...
(5.05 ft³)/(0.5 ft³/bag) = 10.1 bags
10 bags is not quite enough. Rylee should buy 11 bags of potting soil.
_____
Additional comment
As a practical matter, the difference between what Rylee needs and what is contained in 10 bags is about 1%. It would be very difficult to tell that 0.1 cubic foot is missing if Rylee simply used the contents of 10 bags. If Rylee purchases 11 bags, most (4/5) of the last bag will remain unused.
The side lengths of a right triangle are 10, 26, and 24. Which is the hypotenuse?
lVanessa was out shopping with her friends. She had $38
to spend today. She decided to buy herself a pair of sunglasses for $27
and some hair bands that were $2 each. How many hair bands can she
buy?
Answer
5 hair bands
Step-by-step explanation:
$38-$27(Sunglasses)=11
11/2=5.5
you can't buy 5.5 hairbands so you round the number to the nearest whole number.
so the answer is 5 hairbands.

Answer:
[tex]h=5.11ft[/tex]
Step-by-step explanation:
[tex]S=12+6+14/2=16[/tex]
[tex]area ~A= \sqrt{s(s-14)(5-12)(5-6)}[/tex]

What is the perimeter of this shape? Use numbers only. *
Answer:
13
Step-by-step explanation:
The perimeter is all of the sides added together. Because this is a rectangle, the length and width are the same on both sides. They gave you the length and width, so just add them:
4 + 4 + 2.5 + 2.5 = 13.
So the perimeter of the shape is 13.
Answer:
13 m
Step-by-step explanation:
2.5 + 4 + 2.5 + 4
