Answer:
56 square feet
Step-by-step explanation:
If you take the problem and divide into two rectangles by drawing the line up from the bottom 4.
You end up with one rectangle that is
8x4
and a second thats
4x6.
The area is then calculated by taking the length and multiplying by the width of the first (8 x 4) and adding to the same process of the second (4x6)
Thus
32 + 24 = 56 square feet
Answer:
32 + 24 = 56 square feet
A water tank in the shape of a pyramid has a rectangular base with dimensions of 10 feet by 15 feet. The height of the rectangular pyramid is 12 feet. Water fills half the volume of the water tank. How many more cubic feet of water is needed to finish filling the water tank?
(Explanations are appreciated along with your answer.)
600ft³ will be the required volume
Volume of pyramidThe formula for calculating the volume of the rectangular prism is expressed as:
V = 1/3lwhGiven the following information
l = 10 feet
w = 15feet
h = 12 feet
Get the volume
V = 1/3(10 * 15 *12)
V = 1/3(1800ft³)
V = 600ft³
Hence 600ft³ will be the required volume

What equation models the data in the table if d = number of days and c = cost?
what are the y-intercepts to graph the equation-4x - 3y = 36
Answer:
Y-Int = -12
Step-by-step explanation:
First, I would change the equation to slope intercept form:
-3y = 36 + 4x
3y = -36 - 4x
y = -12-4/3x
y = -4/3x - 12
-12 is the y-intercepts to graph the equation-4x - 3y = 36
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The given equation is -4x-3y=36
Now let us convert the given equation to slope intercept form y=mx+b
where m is the slope and b is the y intercept
Isolate the term y
-3y=36+4x
Divide both sides by 3
-y=36/3+4/3x
Multiply both sides by -
y=-12-4/3x
y=-4/3x-12
Slope is -4/3 and y intercept is -12
Hence, -12 is the y-intercepts to graph the equation-4x - 3y = 36

If you deposit $6000 into an account paying 8% annual interest compounded monthly, how much money will be in the account after 7 years?
Answer:
$10278
Step-by-step explanation:
Given data
P= $6000
R= 8%
T= 7 years
The compound interest formula is
A=P(1+r)^t
substitute
A=6000(1+0.08)^7
A=6000(1.08)^7
A=6000*1.713
A=$10278
explain what happens when a transversal has intersected a set of parallel lines.
Answer:
Different angles are formed
Step-by-step explanation:
i) Alternate angles are formed
Alternate interior angles are the angles formed when a transversal intersects two parallel lines.
ii)corresponding angles are formed
When two parallel lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles.

Solve using the substitution method. 3x +2y= 19 xy= 15
Answer:
when x = 3 1/3, y = 4.5
or
when x =3 , y = 5
Step-by-step explanation:
Here, we want to solve using substitution
xy = 15
let x = 15/y
Put this into the first equation;
3(15/y) + 2y = 19
45/y + 2y = 19
Multiply through by y
45 + 2y^2 = 19y
2y^2 -19y + 45 = 0
2y^2 - 10y - 9y + 45 = 0
2y(y-5) -9(y-5) = 0
(2y-9)(y-5) = 0
2y-9 = 0
or y-5 = 0
2y = 9 or y = 5
y = 9/2 or y = 5
y = 4.5 or y = 5
Recall;
x = 15/y
x = 15/4.5 or x = 15/5
x = 3 1/3 or x = 3
Y = A system of equations. Y equals StartFraction 2 over 3 EndFraction x plus 3. X equals negative 2.X + 3 x = –2
Answer: The solution is the pair (-2, 5/3)
Step-by-step explanation:
The system of equations is:
y = (2/3)*x + 3
x = -2
When we have a system of equations, we usually start by isolating one of the variables in one of the equations and then replacing it in the other ones (in that way, we can "remove" variables, until we have only one and we can solve the problem)
In this case, we have already isolated the variable x in the second equation, then we can just replace it in the first one, to get:
y = (2/3)*(-2) + 3
y = -4/3 + 3 = -4/3 + 9/3 = (-4 + 9)/3 = 5/3
y = 5/3
Then the solution of this system is
x = -2
y = 5/3
Which also can be represented with the ordered pair (-2, 5/3)
On the first day of ticket sales the school sold 8 senior citizen tickets and 1 child ticket for a total of $97. The school took in $102 on the second day by selling 6 senior citizen tickets and 4 child tickets. Find the price of a senior citizen ticket and the price of a child ticket.
Answer:
A senior citizen ticket costs $11, and a child ticket costs $9.
Step-by-step explanation:
Let s = price of 1 senior citizen ticket, and let c = price of 1 child ticket.
First day:
8s + c = 97
Second day:
6s + 4c = 102
We have a system of 2 equations in 2 unknowns.
8s + c = 97
6s + 4c = 102
We will use the addition method to solve the system.
Multiply both sides of the first equation by -4. Write the second equation below it and add the equations.
-32s - 4c = -388
(+) 6s + 4c = 102
----------------------------
-26s = -286
Divide both sides by -26.
s = 11
Now substitute s with 11 in the first original equation and solve for c.
8s + c = 97
8(11) + c = 97
88 + c = 97
Subtract 88 from both sides.
c = 9
Answer: A senior citizen ticket costs $11, and a child ticket costs $9.
A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was the percentage decrease in the number of registered members?
Number of registrations a website received during July = 2500
Number of registrations a website received during August = 2245
Number by which the registrations decreased :
[tex] =\tt 2500 - 2245[/tex]
[tex] =\tt 255[/tex]
Thus, the registrations decreased by 255.
Let x be the perrcentage of decrease.
Which means :
[tex] =\tt 255 = \frac{x}{100} \: of \: 2500[/tex]
[tex] = \tt255 = \frac{x \times 2500}{100} [/tex]
[tex] =\tt 255 = \frac{2500x}{100} [/tex]
[tex] = \tt255 \times 100 = 2500x[/tex]
[tex] = \tt25500 = 2500x[/tex]
[tex] =\tt \frac{25000}{2500} = x[/tex]
[tex]\color{plum} =\tt \bold{10.2\%}[/tex]
▪︎Thus, the percentage of decrease in the number of registered members = 10.2%

Cora bought 80 feet of cable for $18.40. She needs 20 more feet. If the unit price is the same, how
much will she pay for the extra 20 feet of cable?
She will pay an extra $
Answer:
Step-by-step explanation:
20ft($18.40/80ft)=$4.60
Answer:
$4.6
Step-by-step explanation:
Use 18.40 and 80. if $18.40 is 80 feet, divide 18.40 by 4 to get 4.60. Now you know that you got 4.60, see if you can add 4.6 four times to get to 18.4. (You can.) So, 20 feet is $4.60 or $4.6.
