To surprise her cousin, Eliana puts confetti in his birthday card before mailing it. At the post office, she learns that her card is 5 grams too heavy for a common stamp. So, she takes out some of the confetti. If each piece of confetti weighs about 50 milligrams, how many pieces does Eliana need to take out?
The number of pieces that Eliana need to take out is; 100 pieces
How to carry out Unit Conversions?
From conversion units, we know that 1 gram (g) is equal to 1000 milligrams (mg). Thus; 1 g = 1000 mg
Now, we are told that at the post office, she learns that her card is 5 grams too heavy for a common stamp. So, she takes out some of the confetti.
However, each piece weighs 50 milligrams. Converting to grams gives us; 50/1000 = 0.05 grams
Thus, number of pieces to take out = 5/0.05 = 100 pieces

Answer:
C. 9.6ft
D. Angle M
Step-by-step explanation:
Height of smaller surfboard = [tex]\frac{12}{4}[/tex] × 3.2ft

If you flip ABCD over, the positions of the angles that are corresponding to each other would be the same, so the angle that would correspond with Angle D would be Angle M since both would be at the top right.
an ice-cream novelty item consists of a cup in the shape of a 4-inch-tall frustum of a right circular cone, with a 2-inch-diameter base at the bottom and a 4-inch-diameter base at the top, packed solid with ice cream, together with a solid cone of ice cream of height 4 inches, whose base, at the bottom, is the top base of the frustum. what is the total volume of the ice cream, in cubic inches?
The total volume of the ice cream, in cubic inches, is [tex]\frac{44\pi }{3}[/tex].
What is Volume?
Cubic capacity is the measurement of a three-dimensional object's volume in cubic units (such as inches, quarts, or centimeters). The volume that material takes up in a given space.Volume, which is measured in cubic units, is the 3-dimensional region occupied by matter or encircled by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume.With a radius of 2 and a height of 4, the top cone has a volume of
[tex]\frac{1}{3} \pi (2)^2X4[/tex].
The frustum is created by subtracting a tiny cone with a radius of 1 and a height of 4 from a large cone with a radius of 2 and a height of 8, giving it a volume of [tex]\frac{1}{3} \pi (2)^2X8-\frac{1}{3} \pi (1)^2X4[/tex]
By combining, we have,
[tex]\frac{1}{3} \pi (16+32-4)\\\\E=\frac{44\pi }{3}[/tex].

On a map, 4 inches equals 160 miles. The distance that a family travels is 6.5 inches on the map. Represent the scale as two different ratios. What is the actual distance the family travels?
Answer:
260 miles.
Step-by-step explanation:
First, find the unit rate (the rate which the numerator is one but the fracvtion is equivilant), in this case the unit rate would be 1/40, or 1:40. Replace the 1 in the ratio ti=o get 6.5:x. Find x. We know that the unit rate is 1:40, so multiply 6.5 by 40 to get 260. Hope this helps!

candy and tim share a paper route. it takes candy 70 min to deliver all the papers, and it takes tim 80 min. how long does it take the two when they work together?
It will take 37.3 minutes if they will work together.
What is the time?Time is the seemingly irreversible succession of existence and events that occur from the past, through the present, and into the future. It is a component quantity of various measurements used to sequence events, compare the duration or intervals between events, and quantify rates of change of quantities in material reality or conscious experience.To find how long it takes the two when they work together:
Let x represent the amount of time it takes them to complete the paper route together.This means that in one minute, they can complete 1/x of the paper route.Candy can complete 1/70th of the route in 1 minute and Tim can complete 1/80th of the route in 1 minute.The part Candy can do in one minute + the part-time can do in one-minute equals the part they can do together in one minute:1/70 + 1/80 = 1/xBecause the LCD has a resolution of 560x, multiply both sides of the equation by 560x:
(560x) · (1/70) + (560x) · (1/80) = (560x) · (1/x)8x + 7x = 56015x = 560x = 560/15 = 37.3 minutes.Therefore, it will take 37.3 minutes if they will work together.

7. The points (3,5) and (2, y) are on a line with a slope of 3. Find y.
Answer:
We get value of y: y = 2
Step-by-step explanation:
The points (3,5) and (2, y) are on a line with a slope of 3. Find y.
We can find y using formula of finding slope of a line.
The formula is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=3, y_1=5, x_2=2, y_2=y[/tex] and Slope = 3
Putting values and finding y
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\3=\frac{y-5}{2-3}\\3=\frac{y-5}{-1}\\-1(3)=y-5\\-3=y-5\\y=-3+5\\y=2[/tex]

12 members are at a conference. they all shook hands with each other both before and after the meeting. how many handshake's were there?
If there are 12 members at a conference and they all shook hands with each other both before and after the meeting, then there were 132 handshakes.
The number of handshakes before and after the meeting between 12 members can be found by using the combination formula.
The combination formula can be given by :
Number of combinations = n! / r! ( n - r)!
Here, n = total number of items in the set
r = number of choosing items from the set
In this problem, n = 12 and r =2 for finding the number of handshakes before the meeting
Therefore,
number of combinations = 12! / 2! ( 12 - 2)!
number of combinations = 12! / 10! × 2!
number of combinations = 66
Hence, there were 66 handshakes before the meeting. To find the number of handshakes both before and after the meeting:
number of total handshakes = 66 × 2 = 132
Hence the number of handshakes before and after the meeting is equal to 132.

solve for x - 4 = 1/4(8x - 16)
Hello!
[tex]\large\boxed{x = 0}[/tex]
x - 4 = 1/4(8x - 16)
Distribute the 1/4:
x - 4 = 1/4(8x) + 1/4(-16)
x - 4 = 2x - 4
Subtract x from both sides:
x - x - 4 = 2x - x - 4
-4 = x - 4
Add 4 to both sides:
-4 + 4 = x - 4 + 4
0 = x

That's quite easy but you need to recall the BODMAS rule .
⠀⠀⠀⠀
BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction
⠀⠀⠀⠀
In this equation we will solve the bracket then we will apply further BODMAS rule
⠀⠀⠀⠀
━━━━━━━━━━━━━━━━━
SolutiOn :➠ x - 4 = 1 / 4 ( 8x - 16 )
➠ 4 ( x - 4 ) = 8x - 16
⠀⠀⠀⠀
➠ 4 ( x - 4 ) = 4 ( 2x - 4 )
⠀⠀⠀⠀
➠ x - 4 = 2x - 4
Now, we will bring the variable on left hand side and constants on right hand side
➠ x - 2x = - 4 + 4
➠ -x = 0
➠ x = -0
➠ x = 0
∴ The value of x is 0 .

If the simple interest on $1,000 for 7 years is $350, then what is the interest rate?
Answer:
24,500
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 350%/100 = 3.5 per year,
then, solving our equation
I = 1000 × 3.5 × 7 = 24500
I = $ 24,500.00
The simple interest accumulated
on a principal of $ 1,000.00
at a rate of 350% per year
for 7 years is $ 24,500.00.
Write and equation in slope-intercept form of the line with slope -1/2 that contains the point (-4,-3)
Answer:
y=-1/2x-5
Step-by-step explanation:
Well we know that the slope is -1/2 so we can write the equation like this:
y=-1/2x+b (This is because of y=mx+b) (m is slope) (b is y-intercept)
Now we can replace the y and x with -4 and -3 because of (x,y). (-4,-3) x is -4 and y is -3
-3=-1/2(-4)+b
-3=2+b
Subtract 2 on both side:
-2-3=2-2+b
-5=b
