does anyone know the answer if you do please post it here
Answer:
Step-by-step explanation:
I know gthis but its To calculate the area of a triangle, multiply the base by the height and divide by two. If you know how to calculate the area of a rectangle, you should be able to calculate the area of a triangle with ease because a triangle is half of a rectangle or square. As a result, because it's half of a rectangle, you should apply the identical approach of calculating the area of a rectangle and then dividing it by two. I hope that's clear!

Find the radius
Volume= 250π³in
Answer:
Volume for a cylinder in this case is
V=˜ πr^2h
So R being radius
H being height
V being volume.
We know the volume is 250π
The height is given in the diagram which is 10.
Plug in the infromation into the formula.
250π = πr^2*10
Simplify and solve for r (radius).
Let’s divide by π on both sides
250 = r^2 * 10
Divide by 10 to get rid of 10
25 = r^2
√25 = r
√25 = 5
The radius is 5

What is the circumference of a circle with a radius of 3.6 units,I don’t really know how to do this because I’m new to this kind of math.
Answer:
22.608 units
Step-by-step explanation:
Basically, the circumference of a circle is the distance around a circle, sort of like the perimeter of a figure. It has a unique formula which is [tex]C=2\pi r[/tex] where [tex]r[/tex] is the radius, which is the distance between the circle and its center. Using our given information, we can find the circumference:
[tex]C=2\pi r\\C=2(3.14)(3.6)\\C=22.608[/tex]
Therefore, the circumference of a circle with a radius of 3.6 units is 22.608 units.
Answer:
Circumference is...
22.608Step-by-step explanation:
Multiply the radius by 2 to get the diameter.
Multiply the result by π, or 3.14 for an estimation.
That's it; you found the circumference of the circle.

Solve the equation to find x.
4x +12 = 96
Answer:
x=21
Step-by-step explanation:
4x+12=96
subtract 12 from both sides
4x=84
divide both sides by 4
x=21
Answer:
x = 21
Step-by-step explanation:
to solve:
1. subtract 12 from both sides:
4x=12=96
-12 -12
2. This gives you 4x=84. Then divide both sides by 4:
[tex]\frac{4x}{4}[/tex][tex]=\frac{84}{4}[/tex]
4x/4 = x
84/4 = 21
So, you get x = 21

Find the area of each figure. Round your answer to the nearest tenth
Answer:
62
Step-by-step explanation:
step 1: find the height of half the yellow coloured triangle (right angled triangle). remember that the angle formed at the center is always 36° for a pentagon.
tan36° = opposite/ adjacent
tan36° = 3/h (h for height)
h × ( tan36°) = 3
h = 3 / tan36°
h = 4.13
step 2: calculate area of the right angled triangle
Area = 1/2 × b × h
= 1/2 × 3 × 4.13
= 6.195
step 3: calculate the area of a Pentagon
a Pentagon can be divided into ten right angled
triangle
6.195 × 10
total area = 61.95
rounded off = 62

You randomly pull two bills, what is the probability that they are both $20?
Answer:
Depends on the pool you are pulling them from.
There are currently 11 different denomination accessible.
That would be 1 out of 11.
But considering that 4 of those bills are uncommon, the odds become 1 out of 7
Then to pull 2 of the same would mean you multiply 1/11 by 1/11 = 1/121
for the 1/7 it would become 1/49

eight students got a B on the final test. Ig the ratio of the number of students who got an A to the number of students who got a B is y: x, how many students got an A? suppose x=4 and y=3
Answer:
the answer is 6
Step-by-step explanation:
there is 8 so you look at x and you see 4 then you look at y and you see 3 so you multiply 4*2=8 because you need eight so then because you multiplied 4*2 you multiply 3*2 and you get 6
Christine bought some necklaces for $14.23 each.
She used a coupon for $15 off, making her total
$41.92. Write an equation to find how many
necklaces Christine bought.
14.23n - 15 = [?]
14.23n - 15 = 41.92
Explanation :
In mathematics "n" denotes any non-negative integer
as in this case "n" denotes the number of necklaces Christine bought
If 1 necklace costs $14.23
n no. of necklaces costs $14.23 × n = 14.23n
She used a coupon for $15 off
so the total amount spent
= the cost for n no. of necklace – $15
= 14.23n – 15
that's technically how the equation given in the question has been derived
total amount spent = $41.92 ( stated in question )
previously we derived an equation for the total amount spent which is = 14.23n – 15
14.23n - 15 = 41.92
14.23n = 41.92 + 15
14.23n = 56.92
n = 56.92 / 14.23
n = 4
no. of necklaces bought = n = 4 necklaces

A store offers discounts on lunch-size chip bags when buying larger quantities. The graph below represents the total cost, in dollars, for the number of bags purchased.
What is the difference in the price per bag for 150 bags versus 50 bags?
The difference in the price per bag for 150 bags versus 50 bags is $0.15 per bag.
What is the difference in the price of the bags?If 150 bags on the x axis is traced to the y axis, the price of the bag is $38.
If 50 bags on the x axis is traced to the y axis, the price of the bag is $20.
Price per bag:
150 bags = 38 / 150 = $0.25
50 bags = $20 / 50 = $0.4
The difference = $0.4 $0.25 = $0.15

After making repairs, a swimming pool owner is going to refill the pool with water. The pool's dimensions are 18\times40\times618×40×6 feet, with each cubic foot equivalent to 2.642.64 gallons, and the cost of water \$0.005$0.005 per gallon. To the nearest dollar, what is the estimated cost of filling the pool?
Answer:
$57
Step-by-step explanation:
I'll assume the pool's dimensions are 18 x 40 x 6.
The total volume is (18 x 40 x 6) = 4320 ft^3.
Use the conversion factor (2.64 gallons/1 ft^3) to find the gallons of water in a full pool. Full pool, cool.
Water (gal) = (4320 ft^3)*(2.64gallons/ft^3) = 11,405 gallons
At $0.005/gal, this would cost (11,405 gallons)*($0.005/gal) = $57.02
$57 to the nearest dollar.

The partial factorization of x2 – x – 12 is modeled with algebra tiles. An algebra tile configuration. 4 tiles are in the Factor 1 spot: 1 is labeled x, 3 are labeled. 1 tile is in the Factor 2 spot and is labeled x. 20 tiles are in the Product spot: 1 is labeled x squared, 3 are labeled x, the 4 tiles below x squared are labeled negative x, and the 12 tiles below the x tiles are labeled negative. Which unit tiles are needed to complete the factorization? 3 negative unit tiles 3 positive unit tiles 4 negative unit tiles 4 positive unit tiles.
The complete factorization of the polynomial x² – x – 12 is (x – 4)(x + 3). The 3 positive unit tiles. Then the correct option is B.
What is polynomial?Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

In a sock drawer there are 8 black socks, 4 red socks and 6 orange socks, none of which are kept in a pair.
What is the probability that you will pull one black sock and one red sock from the drawer with your first two random selections from the drawer?
Show your answer as decimal number, to two decimal places.
Answer:
0.36
Step-by-step explanation:
So the first step is to count up all the socks which is 18. Then I took 2 (because you can't just wear one sock) and multiplied it by 18 and got 36. The question asked for decimal form so I divided it by 100 and got 0.36.
I hope this helps you :)
[tex]2 * 18 = 36\\\\36/100 = 0.36[/tex]
