Natalie likes to mail lots of postcards when she goes on holiday. In 2014 the cost of a single postcard stamp was 0.34
1. Today Natalie buys 10 postcard stamps so what is the total cost of the stamps
2. Natalie and her freinds decide to buy 100 postcard stamps what will be the total cost of the stamps now?
Answer:
1: $3.40 2: $34.00
Step-by-step explanation:
you take 0.34 and multiply it by how many stamps you have. So in this case you have 10 stamps for #1 so you move the decimal over to the right once (since one step is a tenth) and you have $3.40 and for 100 stamps you restart with 0.34 and move the decimal over to the right twice since that would be one-hundredths, and you would get 34. or when you add the units $34.00

Answer:
1/2
Step-by-step explanation:
I got it wrong then it gave me the right answer of 1/2
The fraction of the sweaters that cost $50 or less is 50% is 1/2.
What is a median?It is the middle value of the given set of numbers after arranging the given set of numbers in order.
We have,
From the box plot,
Median = $50
Now,
Median = $50
This means,
50% of the clothes are above $50 and 50% of the clothes are below $50.
Now,
The fraction of the sweaters that cost $50 or less is 50%.
So,
= 50/100
= 5/10
= 1/2

The area of a circle of radius 1 is π units squared. Use scaling to explain why the area of a circle of radius r is πr^2 units squared.
The area of a circle that has a radius that is given as r is πr² units², while if the raidus is r, its area would be π units².
What is the Area of a Circle?Area of circle = πr², where radius is r.
Thus, given that a circle has radius (r) = 1 units
Area of the circle = π(1²) = π units²
If the radius is given as r, the area of the circle remains as πr².
Therefore, the area of a circle that has a radius that is given as r is πr² units², while if the raidus is r, its area would be π units².

1.9x-0.8y=10 what is x
Answer: x = 0.421053y+5.263158
Step-by-step explanation:
x = 0.421053y+5.263158
Answer:
x=0.042105y+10/19
Step-by-step explanation:
Let's solve for x.
19x−0.8y=10
Step 1: Add 0.8y to both sides.
19x−0.8y+0.8y=10+0.8y
19x=0.8y+10

For a school fundraiser, Elena will make pirate masks. She will order masks and print graphics on them. Elena must spend $349 on the printer before she can print any masks and then $4.80 on each mask. If she has $997 how many masks can she print? Answer as a number!
Answer:
135 masks
Step-by-step explanation:
i hope my math is right lol
Answer:
135 masks
Step-by-step explanation:
First, we take $997 and subtract that by $349
$997 - $349 = $648
To find how many masks Elena can print, we divide $648 dollars by $4.80. Since one mask is equivalent to $4.80
$648 ÷ $4.80 = 135
135 masks

The sum of two consecutive integers is – 175. Find the two integers.
Answer:
-88 and -87
Step-by-step explanation:
Since the two unknown integers are consecutive, one will be one more than the other. This means we can express them as x and x+1, so we only have one unknown in our equation. Since they add to -175, we can now write our equation:
x+(x+1) = -175
Take away brackets and combine like terms:
2x+1 = -175
Now we just need to isolate x which we can do by subtracting 1 from both sides and then dividing both sides by 2:
2x+1-1=-175-1
2x = -176
2x/2 = -176/2
x = -88
And our other number is -88+1 = -87
So our two numbers are -88 and -87 which are consecutive and add to 176:
-88+(-87) = -175

Find the substitution 2x+3y=-5 and y=-x+5
Answer: x = 20, y = -15
Step-by-step explanation:
Since we already know that [tex]y=-x+5[/tex], we can just substitute in that value of y into the other equation:
[tex]2x+3y=-5\\2x+3(-x+5)=-5\\2x-3x+15=-5\\-x=-5-15\\-x=-20\\x=20[/tex]
with the value of x, we can find the value of y:

Answer:
No they are not
Step-by-step explanation:
squaring that expression will come out to be a^2-2ab+b^2
this is because you are doing (a-b)(a-b), so you have to multiply each term from the first set of parenthesis by each term in the second set of parenthesis.
a^2-ab-ab+b^2
a^2-2ab+b^2

Write a statement that correctly describes the relationship between these two sequences: 2, 4, 6, 8, 10 and 1, 2, 3, 4, 5.
Answer:
The equation a + d(n-1)
Step-by-step explanation:
Where a is the first number in the sequence, d is the common difference and n is the position of a certain number in the series, e.g
1, 2, 3, 4, 5: a = 1, d = 1 (because 2-1=1, 3-2=1, 4-3=1, etc) and n = 1,2,3...
2, 4, 6, 8, 10: a = 2, d = 2 (because 4-2=2, 6-4=2, etc) and n = 1,2,3,4,5...
So for the second sequence, we could try to get the value of n in n = 6 as follows:
a + d(n-1) where a = 2, n = 6 and d = 2
Thus, 2 + 2(6-1) = 2 + 2(5) = 2 + 10 = 12
So the sixth number in the series would be 12

Is it possible to build a triangle with the side lengths of 9,7, and 16?
Please help! 11pts!!
Answer:
False
Step-by-step explanation:
To be able to build a triangle, the sum of the lengths of any 2 sides must be greater than the length of the third side.
With lengths 9, 7, and 16, 9 + 7 = 16.
You would need 9 + 7 > 16.
Therefore, these sides cannot be used for a triangle.
2. A dress that originally costs $89.75 is on sale for 30% off.
Answer: $62.82
Step-by-step explanation:
In a race, a bicyclist travels 3 miles in 1/4 hour. Determine the unit rate for the speed
in miles per hour.
3/4 miles per hour
16 miles per hour
11/4 miles per hour
12 miles per hour
Step-by-step explanation:
the standard measure for speed is
miles per hour.
now we got as measurement
3 miles per 1/4 hour.
to give the standard speed or "unit rate" we assume that the bicyclist maintains the same speed for a whole hour.
and the question is : how many miles is he traveling then in that 1 hour ?
to answer this we have to check how often the actually measured unit of time fits into 1 hour.
1/4 hour fits 4 times into 1 hour.
and that factor applies now also to the miles to keep the value of the rate or ratio unchanged :
miles/time × a/a = miles×a/(time×a)
so that (time×a) = 1 hour
and so, he traveled 3×4 = 12 miles per hour.
