Jeremiah plans on building a garden walkway 5 meters long with stones that measure 5/6 meter on each side. There will be no spaces in between. How many stones are needed?
Answer: 6
Step-by-step explanation:
From the question, we are informed that Jeremiah plans on building a garden walkway 5 meters long with stones that measure 5/6 meter on each side.
The number of stones that are need would be gotten by dividing 5 by 5/6. This would be:
= 5 ÷ 5/6
= 5 × 6/5
= 30/5
= 6
Therefore, the answer is 6.

how do you find the volume of a cylinder describe which measurements of the cylinder you need to know
Answer:
To calculate the volume of a cylinder, you need to know its height and the area of its base. Because a cylinder is a flat-top figure (a solid with two congruent, parallel bases), the base can be either the top or bottom

Which expression is equivalent to - 2/3 (6x + 15) ?
A.
4x + 10
B.
4x – 10
C.
-4x - 10
D.
- 4x + 10
Answer:
-4x - 10
Step-by-step explanation:
Given the expression -2/3(6x+ 15)
Open the bracket
-2/3(6x+ 15)
= -2/3 (6x) -2/3(15)
= -2(2x) - 2(5)
= -4x - 10
hence the equivalent expression is -4x - 10

Answer:
[tex]\Huge\boxed{\$ 12.12}[/tex]
Step-by-step explanation:
In order to find how much credit is left after 92 minutes, we need to
1. Figure out the equation that describes this graph (since we don't know the y-intercept)
2. Find the credit remaining after 92 minutes using the equation formed.
Figuring out the equation of this graph:First things first is to figure out the slope of this graph. Since this is a linear function, the slope will remain constant, and we can note something about slope here.
The slope of a line will be it's change in x divided by its change in y, often referred to with a formula.
[tex]\frac{\Delta y}{\Delta x}[/tex]
Since we know two points on this graph, we can find the changes in the x and y then divide for the slope.
Since minutes used is the x, and credit left is the y, we have two points.
(41, 19.26) and (68, 15.48).
The change in y is -3.78, as [tex]19.26-15.48=3.87[/tex], and we decreased, so -3.78.The change in x is 27 as [tex]68-41=27[/tex], and we increased.The slope will then be [tex]\frac{-3.78}{27}[/tex] which comes out to be -0.14.
Now that we know the slope, that means our equation will look something like [tex]y = -0.14x+b[/tex] - however, we still have b to solve for!
To solve for it, we can substitute one of our points in - let's do (41, 19.26) - to the equation and solve for b.
[tex]19.26 =-0.14 \cdot 41 +b[/tex] [tex]19.26 = -5.74+ b[/tex] [tex]b = 19.26+5.74[/tex] [tex]b = 25[/tex]Now that we know that b = 25, we can plug it into our equation, making the final equation that represents this scenario
[tex]y = -0.14x+25[/tex]
Solving for 92 minutesNow that we know the equation to our graph, we can substitute in 92 minutes as the x value to find our y value (credit left).
[tex]y = -0.14 \cdot 92 + 25[/tex] [tex]y = -12.88+25[/tex] [tex]y =12.12[/tex]Therefore, after 92 minutes, the amount of credit left is $12.12

Answer: 180
Step-by-step explanation:
Measurement of <1 please help
Answer:
27°
Step-by-step explanation:
Triangles when all three sides are added up make up 180°. So In this problem you would need to add up 80 and 73 (153) then subtracting that number by 180 (27) to find the value/measurement of <1.
A student committee is organizing a school dance as a fundraiser. The function f ( x ) = 5 x − 320 represents the total amount of funds raised based on the number of tickets sold, x , minus the cost of decorations
I assume you want this explained
Answer and explanation:
If the function f ( x ) = 5 x − 320 represents the total amount of funds raised based on the number of tickets sold, x , minus the cost of decorations then x number of tickets is an independent variable here that will determine the total amount of funds raised y(dependent variable)
The y intercept is -320 and the slope is 5
If for example the number of tickets sold = 100 tickets
Total amount of funds using the function :
f(100)= 5×100-320
=500-320
= $180
Answer:
The slope of the function is 5, and it represents the price of each ticket .

The radius of a circle is 1 centimeter. What is the area of a sector bounded by a 90° arc?
Answer:
[tex]Area = 0.785cm^2[/tex]
Step-by-step explanation:
Given
[tex]r = 1cm[/tex] -- radius
[tex]\theta = 90^{\circ}[/tex]
Required
Determine the area of the sector
This is calculated as:
[tex]Area = \frac{\theta}{360} * \pi r^2[/tex]
Substitute values for r and [tex]\theta[/tex]
[tex]Area = \frac{90}{360} * \pi * (1)^2[/tex]
Simplify 90/360
[tex]Area = \frac{1}{4} * \pi * (1)^2[/tex]
[tex]Area = \frac{1}{4} \pi[/tex]
Take [tex]\pi[/tex] as 3.14
[tex]Area = \frac{1}{4} * 3.14[/tex]
[tex]Area = 0.785cm^2[/tex]

the diameter of a pearl is about 4×10-¹⁴ cm and the diameter of an atom is about 10-¹¹ m. how much larger than an atom is a pearl?
Answer:
The diameter of an atom is 25000 times the diameter of a pearl.
Step-by-step explanation:
Given that,
The diameter of a pearl is [tex]4\times 10^{-14}\ cm[/tex]
The diameter of an atom is [tex]10^{-11}\ m=10^{-9}\ m[/tex]
Taking the ratio,
[tex]\dfrac{\text{diameter of an atom}}{\text{diameter of a pearl}}=\dfrac{10^{-9}\ m}{4\times 10^{-14}\ m}\\\\=25000[/tex]
So, the diameter of an atom is 25000 times the diameter of a pearl.
x + 3y = 18
-X - 4y = -25
Answer:
x = -3
y= 7
Step-by-step explanation:
x + 3y=18 ----(1)
-x - 4y=-25 -----(2)
from equation (1)
x = 18 - 3y ---(3)
putting equation (3) into equation (2)
-(18 - 3y) - 4y = -25
18 + 3y -4y = -25
3y - 4y = -25 - 18
-y = -7
y = 7 ✓
Putting y=7 into equation (1)
x + 3(7) = 18
x + 21 = 18
x = 18 - 21
x = -3 ✓
