Answer:
Step-by-step explanation:
The perimeter of squares is just 4s
Since the bigger square has sides of 2x+1 and the smaller has sides of x the difference of perimeters is
d=4(2x+1-x)
d=4(x+1)
d=4x+4, and d=16 so
4x+4=16
4x=12
x=3 so the smaller square has sides of 3 and an area of
A=x^2
A=3^2
A=9

Challenge A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. of the coins, 16% are pennies and 32% are dimes. There are 6 more nickels than pennies. How much money does the bag contain?
Answer:
Step-by-step explanation:
p+n+d+q=50
p=.16(50)=8
n=p+6=8+6=14
d=.32(50)=16
q=50-p-n-d=50-8-14-16=12
A=8(1)+14(5)+16(10)+12(25)
A.=8+70+160+300
A=538 cents
A=$5.38

a rectangular field is 3x meters long and 2x meters wide its perimeter is 250 meters the value of x is?
Answer:
Given:
Length = 3x m
Breadth = 2x m
Perimeter = 250m
Need to find:
The value of x=?
Solution:
We know,
Perimeter of rectangle = 2×(length + breadth)
Substitute the values!
→ 250m = 2 ×( 3x + 2x) m
→ 250 = 2 × 5x
→ 10x = 250
→ x = 25

Area of a rectangle = Length × Breadth
Area of square = Side × Side
Area of rhombus=
Perimeter of square = 4× side

the lablel on a 1/2- pound bag of wildflower seeds states that it will cover an area of 375 square feet . based on this information, what is the number of square feet that 1 pound of wildflower seeds will cover.
Answer: so a 1 and 1/2 bag will cover 375
1=2/2
1 and 1/2=2/2 and 1/2=3/2
so 3/2 pound covers 375
2/2 pounds covers x
3/2pound=375
multiply both sides by 2 to get rid of the fraciton
3pound=750
divide both sides by 3
1pound=250 square feet so the answer is c. 250 square feet

Answer:
They say.. use Pythagorean theorem formula.... what is it? :) you have to remember it. I'll put it below in case you don't remember
Step-by-step explanation:
[tex]C^{2}[/tex] = [tex]A^{2}[/tex] +[tex]B^{2}[/tex]
and I know, you're thinking..... what's the deal with all the letters... how do I add those up? :D ..... you are right... you can't add letters... the letters are just the variables... or places holders for numbers... you can put many different numbers into each of them but... the relationship.... which is made by the equal sign.. must hold true for any numbers you put in for the variables.... sooo.. like this.. for your particular answer
[tex]19^{2}[/tex] = [tex]10^{2}[/tex] + [tex]y^{2}[/tex]
( notice I've put in a " y " , where there is a B in the formula above but that's just a letter... again.. which is just a variable... the place holder for a number... soooo..... )
361 = 100 + [tex]y^{2}[/tex] ( subtract 100 from each side of the " = " )
261 = [tex]y^{2}[/tex] ( to undo the square on the wye... square root both sides)[tex]\sqrt{261}[/tex] = y
my calculator tells me that [tex]\sqrt{261}[/tex] = 16.15549442
they say round to the nearest 10th... soooo..
16.2 is the answer :)
The product of two consecutive numbers is 72. Use a quadratic equation to find the two sets of numbers.
Given:
The product of two consecutive numbers is 72.
To find:
The two numbers by using the quadratic equation.
Solution:
Let the two consecutive numbers are x and (x+1).
The product of two consecutive numbers is 72.
[tex]x(x+1)=72[/tex]
[tex]x^2+x-72=0[/tex]
Splitting the middle term, we get
[tex]x^2+9x-8x-72=0[/tex]
[tex]x(x+9)-8(x+9)=0[/tex]
[tex](x+9)(x-8)=0[/tex]
Using zero product property, we get
[tex]x+9=0[/tex] and [tex]x-8=0[/tex]
[tex]x=-9[/tex] and [tex]x=8[/tex]
If [tex]x=-9[/tex], then
[tex]x+1=-9+1[/tex]
[tex]x+1=-8[/tex]
If [tex]x=8[/tex], then
[tex]x+1=8+1[/tex]
[tex]x+1=9[/tex]
Therefore, the two consecutive numbers are either 8,9 or -9,-8.

Answer:
$1040
Step-by-step explanation:
Firstly, we must lay down all the details given..
●The price increased by 30% that means that the original price which was 100% is now 130%
●The present price which is the original price for now is 100%.
One way we can show these details is by mathematical term, proportional method.
So,
100%= $800
1%=800÷100
130%= 800÷100×130
= $1040

Torrie could buy 8 jars of peanut butter for 27.12 or 7 jars of peanut butter for 26.53 what is the difference in the unit rates of the jars of peanut butter?
Answer:
The difference in the unit rates of the jars of peanut butter is 0.4.
Step-by-step explanation:
In order to find the unit rates, you have to divide each price for the amount of units purchased with that price, which is:
27.12/8=3.39
26.53/7=3.79
Now, that you have the unit rate for each case, you have to subtract 3.39 from 3.79 to find the difference in the unit rates:
3.79-3.39=0.4
According to this, the answer is that the difference in the unit rates of the jars of peanut butter is 0.4.

Answer:
The owner makes $2 in sales per customer
Note: The "Amount of sales" label of the question is phrased poorly. s could be better labeled "profit from sales" or at least "Amount made from sales", etc.
Step-by-step explanation:
If you logically think about how the answer (now that you know it) relates to the question, it should make simple sense.
i.e. if you consider the first column where $24 is made from 12 customers, and divide the $24 made by the 12 customers, you'll see that each customer spends $2.
Answer:
the owner makes 2 dollars in sales every week
Step-by-step explanation:
on the chart/graph it shows 6 new customers every week and if you want to see how much more money the owner makes off of each customer then...
subtract the first weeks number of customers from the second weeks to get the answer of 6 new customers per week as you can see on the chart/graph (this really isnt to important though)
then divide the total number of customers for 1 week by the profits made for that week to get an answer of 2 dollars for customers.

What's the slope of the line?
Answer:
3
Step-by-step explanation:
lets just take two random points that are on the line ( it doesn't have to be a specific point)
(-2,0) and (-1 , 3) cuz why not
we need to find the difference of both the y coordinates divided by the difference of both the x coordinates
0-3 / -2 - (-1)
-3 / -1
3/1 = 3
Answer:
choose two random points of the line and....

Answer:
422.5
Step-by-step explanation:
Given,
Diameter = 23.2
Radius = 23.2 ÷ 2 = 11.6
So, Area is
[tex] = \pi {r}^{2} [/tex]
[tex] = 3.14 \times 11.6 \times 11.6[/tex]
= 422.5184
As rounding to nearest tenth we check the hundreth digit i. e.
422.5184
Since, 1 is smaller than 5 so,
422. 5 (Ans) (Rounded to nearest tenth)
