Answer:
1795.5 [tex]m^3[/tex]
Step-by-step explanation:
find area of base (it's a trapezoid)
[tex]\frac{b_1+b_2}{2} *h\\\\=\frac{11+16}{2} *9.5\\\\= 13.5*9.5\\\\=128.25[/tex]
multiply area of base by height
128.25 x 14
= 1795.5 [tex]m^3[/tex]

You own a house with an appraised value of $300,000. Your equity in the home is $125,000. What is your mortgage balance?
Answer:
The mortgage balance is $175,000
Step-by-step explanation:
Remember: House value = equity + mortgage. Therefore,
$300,000 = $125,000 + mortgage balance
The mortgage balance is $175,000.

(7x + 10y = 11
(4x + 3y = -10
Answer:
x=-7
y=6
Step-by-step explanation:
7x+10y=11
4x+3y=-10
-3(7x+10y=11
10(4x+3y=-10
-21x-30y=-33
40x+30y=-100
19x = -133 (divide 19 on both sides)
x= -7
Now put the x in one of the original questions.
7(-7)+10y=11
-49+10y=11 (Add 49 to both sides)
10y=60 (Divide 10 on both sides)
y=6

A regular polygon with exterior angle of 45° is redrawn using a scale 1 : 5. If the actual length of the sides of the regular polygon is 10cm, calculate the perimeter of the scale drawing of the regular polygon.
Answer:
16 cm
Step-by-step explanation:
"regular polygon" means all sides and angles are the same.
the sum of all exterior angles must be 360 degrees.
so, how often do 45 fit into 360 ?
2 times in 90, which in turn fit 4 times into 360, so 8 times.
the polygon has 8 corners and 8 sides.
each side is originally 10cm
so the original perimeter is 8×10 = 80 cm
now, every side is reduced to 1/5th of the original size, this also reduces the perimeter by the same factor.
=> perimeter = 80×(1/5) = 80/5 = 16 x cm
control :
applying the scaling factor of 1/5th to every side transforms every side from 10 cm to 2 cm.
we still have 8 sides.
perimeter = 8 × 2 = 16 cm
correct

Escribe el nombre de algún tipo de ángulo que se forma "Entre Dos rectas Paralelas y una Secante"
Answer:
We see that opposite angles are two angles between two secant lines (“secant lines” simply means two lines that cross each other) that share a vertex (that is why they are called “vertical” angles). We see also that they are not adjacent (which means next to each other) but opposite each other.
Step-by-step explanation:
Vemos que los ángulos opuestos son dos ángulos entre dos líneas secantes (“líneas secantes” simplemente significa dos líneas que se cruzan) que comparten un vértice (por eso se llaman ángulos “verticales”). También vemos que no son adyacentes (lo que significa uno al lado del otro) sino uno frente al otro.

AN ALGEBRAIC EXPRESSION IS ____ WHEN ALL LIKE TERMS HAVE BEEN ___
Is it
Variable/ combined
Or
Variable/ simplified
Or
Simplified / combined
Or
Combined / s impfied
Answer:
I think it will be combined and simplified
Answer:
Simplified/combined
Explanation:
In order to simplify an algebraic expression you need to combine all of the like terms which have the same variables and powers.
Copy PQ to the line with an endpoint at R.
This task will be complete when you have
drawn an arc intersecting the line to create
a segment with length PQ.
Answer: Hello your question lacks some details attached below is the complete question
answer:
Place a compass at point Q , measure arc PQ Draw an arc with the compass that is equal to PQ , Place the compass at point R , cut through the line to the left of R with the arc in compass, Assume the new points to be P' and R be Q' , where P' Q' will become the new image of PQ with their end point will be RStep-by-step explanation:
The steps required to draw an arc intersecting the line that will create a segment with length PQ are ;
Place a compass at point Q , measure arc PQ
Draw an arc with the compass that is equal to PQ , Place the compass at point R , cut through the line to the left of R with the arc in compass,
Assume the new points to be P' and R be Q' , where P' Q' will become the new image of PQ with their end point will be R
Answer:
Set the compass width to the length PQ by putting one end on P and the other and on Q
Without changing the width, move the compass so one end is on R and the other end is on the line containing R
Draw an arc across the line using R as the center
Mark the point where the arc crosses the line as point S
RS is the copied segment.
Step-by-step explanation:
Line A has a slope of 3/2 and passes through the point (3, 3). Line B has a slope of – 1/3 and passes through the point (-4, -2). At what point does line A intersect line B? Line Aintersects line B at the point ( , ).
Answer:
The lines meet at (-1, -3)
Step-by-step explanation:
Line A :
[tex](x_1, y_1) = (3, 3) \ ; \ slope, \ m_A = \frac{3}{2}\\\\Equation \ of \ line \ A : (y - 3) = \frac{3}{2}(x - 3)[/tex]
[tex]2(y - 3) = 3(x-3)\\2y - 6 = 3x - 9\\2y = 3x - 9 + 6\\2y = 3x -3[/tex]
Line B :
[tex](x_2,y_2) = (-4, -2) \ ; \ slope , m_B = -\frac{1}{3}\\\\Equation \ of\ line \ B: (y -(-2)) = -\frac{1}{3}(x -(-4))[/tex]
[tex]3(y + 2) = -1(x+4)\\3y + 6 = -x -4\\3y = -x - 4 - 6 \\3y = -x - 10[/tex]
Solve for x and y from the linear equation to find where line A and line B meets :
2y = 3x - 3 => 3x - 2y = 3 ------- (1)
3y = -x - 10 => -x = 3y + 10
=> x = - 3y - 10 --------(2)
Substitute (2) in (1) : => 3(- 3y - 10) - 2y = 3
-9y - 30 -2y = 3
-11y = 3 + 30
-11y = 33
y = -3
Substitute y in (2) : => x = -3 (-3) - 10 = 9 - 10 = -1

Explain the difference between finding the volume of this right rectangular prism with whole unit cubes and with 1/2 unit cubes.
help is appreciated :)
Answer:
Rectangular prisms are six-sided polygons; three-dimensional shapes of which all sides meet at 90-degree angles, like a box. Cubes are a special type of rectangular prism of which all sides are the same length; this is the key difference between cubes and other rectangular prisms.

what is the difference between the domain and the range of a function?
Answer:
The domain is all the x values of a function while the range is all the y values of a function.
Answer:
Step-by-step explanation:
The domain of a function is the set of input (x-) values for which the function is defined. The range is the set of output (y-) values; often there are limitations.
For example, the sine function y = sin x is defined for all real x; for every input x, there is a corresponding output y. The sine function has a limited range in that the minimum value of the sine is -1 and the max is +1. There is no graph above y = -1 or below y = +1.

Your adjacent is 3, your opposite is 4, and you have a 90 degree angle. Find the value of cos V rounded to the nearest hundredth, if necessary.
Answer:
0.6 or [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
Using the Pythagorean theorem ([tex]a^{2} +b^{2} =c^{2}[/tex]) we get that the hypotenuse is 5.
so the cos V is adjacent over the hypotenuse. so if adjacent is 3 and hypotenuse is 5, the answer is [tex]\frac{3}{5}[/tex] which equals 0.6 in decimal form.
