Answer:
260 gallons
Step-by-step explanation:
An estimate of 26.5% of the water used each day is for cleaning and a family uses 68.9 gallons of water a day for cleaning,
Percentage of water used for cleaning= 26.5%
Gallons of water used for cleaning= 68.9
Let the number of gallons used everyday be represented by g. This will give:
26.5% of g = 68.9
26.5/100 × g = 68.9
0.265 × g = 68.9
0.265g = 68.9
Divide both side by 0.265
0.265g/0.265 = 68.9/0.265
g= 260
260 gallons of water are used everyday
Given the function h(x) = -x2 -X2 – 5x + 8, determine the average rate of change of the function over the interval -4 < x < -2
Hi there!
[tex]\large\boxed{\text{Average rate = 1}}[/tex]
We can calculate the average rate of change using the following:
[tex]ARC = \frac{f(b)-f(a)}{b-a}[/tex]
Thus, we can plug in the endpoints of -4 and -2. Find the corresponding y-values for these x-values:
f(-2) = -(-2)² - 5(-2) + 8 = -4 + 10 + 8 = 14
f(-4) = -(-4)² - 5(-4) + 8 = -16 + 20 + 8 = 12
Plug in the solved for values into the ARC equation:
[tex]ARC(slope) = \frac{14-12}{-2(-4)} = \frac{2}{2} = 1[/tex]

NO LINKS ACCEPTED -The robot factory is a learning center where children can build robots. The project fee per visit is $15 and each hour of time (x) at the factory costs $4. Jesse goes to the robot factory one afternoon and was charged $40 for the visit. Write an equation that models this situation where X is the number of hours Jesse stands at the robot factory
Answer:
15 + 4x = 40
Step-by-step explanation:
To construct this equation, we'll list all the values we will include first.
The total fee equals $40, so we'll put 40 on one side of the equation.
On the other side, we have to put the values that make up the total. The fee is made with the project cost plus the hourly rate. The first part of this is the beginning cost, $15. Added to this is the hourly cost, $4, times the number of hours spent. So, the other side of the equation is 15 (the starting cost) plus 4 (the rate) times x (the unknown number of hours).
So, our equation is 15 + 4x = 40.
Good luck ^^
show work please find the volume of the following irregular space figure to the nearest whole number
Answer:
144cm^3
Step-by-step explanation:
1) split the figure so you can find the volume of two rectangular prisms.
2) Find the volume of the first rectangular prism with the measurements of 2, 5, and 8. So the volume is 80
3) Find the volume of the second rectangular prism with the measurements of 4, 2, and 8. So you have 64
4) Add the two values 80+64.
5) Then that's your answer; 144
Hope this helps! :D
Out of Koley's 15 plants, 6 were carrots. What percentage of plants are carrots?
**And don’t even bother putting a link...
Answer:
40%
Step-by-step explanation:
➡6/15×100
➡600/15
➡40%
Answer: 40% of the plants are carrots
Step-by-step explanation:
In order to figure out the percentage, we have to find what "part" of the "total" are the carrots, which is given. We already know that 6 of the total 15 plants are carrots. When referring to a percentage, basically we are trying to find out how many carrots there would be, if we were to have 100 plants. So, in order to do so, we would need 100 plants. I'll make it even more simple:
We have 15 plants - 6 of which are carrots
If we were to have
100 plants - HOW MANY would be carrots??
The answer to our question is also the percentage we are looking for. If we replace HOW MANY with x, than we would have this equation: 15*x=6*100, so 15x=600 and x=40, so the percentage is 40%.
In order to make this easier, as i said in the beginning we are referring to the part of a total, with given numbers, so if we would divide 6 out of 15, we would have 6/15=0.4 , multiplying that number with 100 (for the percentage), you get 40% again, with a faster and easier way. Practice makes perfect.

Answer:
-2
Step-by-step explanation:
Lily walks 2 kilometers during each trip to school. Write an equation that shows the
relationship between the number of trips x and the total distance walked y.
Answer:
y = 2x
Step-by-step explanation:
Total distance walked = y
Number of trips = x
Lily walks 2 kilometers during each trip to school
Equation that shows the
relationship between the number of trips x and the total distance walked y:
y = 2x
For example, if the number of trips (x) is 3
Total distance walked,y = 2(3)
y = 6 kilometers

Answer:
∠CBE = 59°
Step-by-step explanation:
Adjacent angles of a parallelogram are supplementary.
∠BCD +∠CDE = 180°
∠BCD +∠CDB +∠BDE = 180°
(21x -5) +34 +(4x+1) = 180
25x +30 = 180
25x = 150
x = 6
∠CBE = ∠CDE = 34 +(4x +1) = 4x +35 = 4(6) +35
∠CBE = 59°

A variable y varies directly with x and the constant of variation is 3. What is the value of y when x = 2?
Answer:
y = 6
Step-by-step explanation:
y varies directly with x
y = k*x
Where,
k = constant of variation
Find y when x = 2 and constant of variation,k =3
y = k*x
y = 3 * 2
y = 6
Check:
if y = 6 and x = 2, find k
y = k*x
6 = k*2
6 = 2k
k = 6/2
k = 3

Answer:
z = 8
Step-by-step explanation:
All angles inside a triangle add up to 180 so:
90 + 40 + 5z + 10 = 180
5z + 140 = 180
5z = 40
z = 8
Please help me with this !!
Answer:
Step-by-step explanation:
a = 1
b = 6
c = 6
axis of symmetry = -(6) / 2*1
= -6 /2
= -3
vertex = ( -3, -3 ) :)
Answer:
Step-by-step explanation:
a = 1 because if is not written what x^2 multiply, it means that x^2 multiply 1
b = 6 b is the term that multiply x
c = 6 c is the therm without x
axis of symetry = -6/2 = -3
the x of vertex is same of the axis of the symmetry so it is -3
if we subistute x with this value we can find the y of vertex
(-3)^2 + 6(-3) + 6 = 9 -18 + 6 = -3
Vertex (-3, -3)
Look at the drawing of a triangle within a rectangle. The
triangle and the rectangle have the same base, b, and
height, h.
If the area of the triangle is 48 square units, what is the
total area of sections 1 and 2?
square units
) Intro
Answer:
48 square. Units
Step-by-step explanation:
Given that :
Triangle and rectangle have the same base, b and height, h
AREA of triangle = 0.5 * base * height
48 = 0.5 bh
bh = 0.5 * 48
bh = 96
Total area of section 1 & 2 :
bh = area of triangle + x
X = bh - area of triangle
X = 96 - 48
Area of se tion 1&2 = 48
Solve for x and solve for FGI
Answer:
X equals -0.5 in decimal and in fraction it would be negative one half. Im not 100% sure of the answer also I dont know what angle that is...
