The circumference of the larger circle is approximately 22 meters and the circumference of the smaller circle is approximately 11 meters. Use a proportion to find the approximate diameter of the smaller circle. If necessary, round your estimate to the nearest tenth.
Answer: approximately 3.5 meters.
Step-by-step explanation:
Given: Circumference of the smaller circle is approximately 11 meters.
Circumference of a circle = [tex]\pi d[/tex] , where d= diameter.
Ratio of circumference to diameter = [tex]\pi[/tex]
As per given,
[tex]\pi=\dfrac{11}{d}\\\\\Rightarrow\ d=\dfrac{11}{\pi}\\\\\Rightarrow\ d=\dfrac{11\times7}{22}\ \ \ [\pi=\dfrac{22}7]\\\\\Rightarrow\ d=\dfrac72=3.5\ meters[/tex]
Hence, the diameter of the smaller circle is approximately 3.5 meters.

What is the last digit of
[tex]1 \times 3 \times 5 \times 7 \times 9 \times 11 \times 13[/tex]
A. 1
B. 3
C. 5
D. 7
Step-by-step explanation:
When a number is multiplied by 5, the last digit of the product must be 0 (mod 5).
=> Last digit = 0 or 5.
Since 0 is not an option here, the answer must be 5. (C)
Answer:
Answer C. 5
Step-by-step explanation:
Product of Odd and Even Numbers
Any number ending in 5 is necessarily a multiple of 5. For example, 85, 1005, 12345 are all multiple of 5.
Any number ending in 0 is a multiple of 5 and even therefore, is a multiple of 10.
Any integer number multiplied by another number ending in 5 gives one of these possible results:
* A multiple of 5 if the number is odd
* A multiple of 10 if the number is even.
The given product 1*3*5*7*9*11*13 is a multiple of 5 because 5 is one of the factors, and since the rest of the factors are all odd numbers, then the result is a multiple of 5 and has its last digit of 5.
Answer C. 5

solve the following systems of equations by elimination
4x - 5y = 9
- 6x + 5y = -11
Answer:
Therefore, x = 1 and y = -1 .
Step-by-step explanation:
The steps are :
[tex]4x - 5y = 9 - - - (1)[/tex]
[tex] - 6x + 5y = - 11 - - - (2)[/tex]
[tex](1) + (2)[/tex]
[tex]4x + ( - 6x) = 9 + ( - 11)[/tex]
[tex] - 2x = - 2[/tex]
[tex]x = 1[/tex]
[tex]sub \: x = 1 \: into \: (2)[/tex]
[tex](2)⇒[/tex]
[tex] - 6(1) + 5y = - 11[/tex]
[tex] - 6 + 5y = - 11[/tex]
[tex]5y = - 11 + 6[/tex]
[tex]5y = -5[/tex]
[tex]y = -1 [/tex]
Answer:
I hope it work
Step-by-step explanation:
4x-5y=9 -6x+5y=-11adding both the equations
4x-5y=9
-6x+5y=-11
-2x+0y=-2
-2x=-2
Now divide both sides by -2
-2/-2 x= -2/-2
x=1Now putt the value of x in one of above equation to get value of y4(1)-5y=9now solve this-5y=9-4-5y=5divide -5 to both sidesy= -1These are he required value of x and yplease Brain-list the answer if u like it thanks...Help me pls and thanks

Simplify (1 + 3)2 – 10 = 2.
Answer:
-2 ≠ 2
Step-by-step explanation:
(1 + 3)2 – 10 = 2
(4)2 - 10 = 2
8 - 10 = 2
-2 ≠ 2
Hey there!
“Simplify (1 + 3)2 – 10 = 2”
IN ORDER FOR YOU TO SOLVE FOR THIS EQUATION YOU HAVE TO DO PEMDAS

- (E)xponents
- (M)ultiplication
- (D)ivsion
- (A)ddition
- (S)ubtraction
(1 + 3)2 – 10 = 2
(1 + 3) = 4
4(2) – 10
4(2) = 8
8 – 10 = –2
Answer: –2 ≠ 2 so this makes this statement FALSE

Answer:
Part a y=10.99+1.25x
Part B 14.74
Answer:
Part A) 10.99 + x = y
Part B) 14.74$
Step-by-step explanation:
In part A, you add the number of toppings to the pizza. Making the expression: Pizza Cost + Topping = Total Amount.
In part B, you do 1.25*3 = 3.75 (Cost of 3 toppings) + 10.99 (Cost of the pizza) = 14.74$

question is which function has a greater y-intercept?
answers:
function 1
function 2
The same function gave the same y-intercept
Answer:
The same function gave the same y-intercept
Step-by-step explanation:
Y-intercept can be calculated when x is 0. This is easy to figure out the table because it already gave us the value of y when x was 0, which was 3.
For the first function, we know that it has a y-intercept of 3.
For the second function, getting the y-intercept is very easy because you can look at the value of y at x=0. We can physically see that it is 3, meaning that they both have the same y-intercept.
The scale of a map is given as 1 : 20000000. Two cities are 6 cm apart on the map. Find the actual distance between them.
Answer:
The actual distance between the cities is 1,200 Km
Step-by-step explanation:
Scaling
Objects can be represented in a reduced or augmented size by using scaling which is multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.
We are given the scale on a map as 1:20,000,000.
Two cities are 6 cm on the map. The actual distance is obtained by multiplying:
6 * 20,000,000 = 120,000,000 cm
Divide by 100 to convert to meters and by 1,000 to convert to km 120,000,000/100/1,000=1,200 Km
The actual distance between the cities is 1,200 Km

A store pays $ 56 for a cell phone. The store marks the price at 20%. What is the quantity of the mark?
Answer:
The quantity of the mark is $11.20
Step-by-step explanation:
Given that:
Amount paid by store for cell phone = $56
The store marks the price at 20%.
Quantity of the mark = 20% of 56
Quantity of the mark = [tex]\frac{20}{100}*56[/tex]
Quantity of the mark = 0.2 * 56
Quantity of the mark = $11.20
Hence,
The quantity of the mark is $11.20
