Let's first just do the multiplication and ignore the decimal points.
2073 x 4 = 8292.
Now there are 3 decimal points we need to consider. So, that gives us an answer of 8.292

Charlotte is making pies for her whole family. So far, she has made 5.04 pounds worth of pie, and has 7 people to feed, including herself. How much does each person get if Charlotte is done making pies?
Answer:
0.72 pounds
Step-by-step explanation:
Each of the 7 people gets 1/7 of the pounds of pie, so ...
(5.04 pounds)/7 = 0.72 pounds
Each person gets 0.72 pounds of pie.

Answer:
[tex]1-\cos \left(x\right)[/tex]
Step-by-step explanation:
[tex]\frac{\sec \left(x\right)\sin ^2\left(x\right)}{1+\sec \left(x\right)}[/tex]
Use the identity: [tex]\sec \left(x\right)=\frac{1}{\cos \left(x\right)}[/tex]
[tex]\frac{\frac{1}{\cos \left(x\right)}\sin ^2\left(x\right)}{1+\frac{1}{\cos \left(x\right)}}[/tex]
[tex]\frac{\frac{1}{\cos \left(x\right)}\sin ^2\left(x\right)}{\frac{\cos \left(x\right)+1}{\cos \left(x\right)}}[/tex]
[tex]\frac{\frac{\sin ^2\left(x\right)}{\cos \left(x\right)}}{\frac{\cos \left(x\right)+1}{\cos \left(x\right)}}[/tex]
Divide them using [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\times d}{b\times c}[/tex]
[tex]\frac{\sin ^2\left(x\right)\cos \left(x\right)}{\cos \left(x\right)\left(\cos \left(x\right)+1\right)}[/tex]
Cancel cos(x):
[tex]\frac{\sin ^2\left(x\right)}{\cos \left(x\right)+1}[/tex]
Use the identity: [tex]\sin ^2\left(x\right)=1-\cos ^2\left(x\right)[/tex]
[tex]\frac{1-\cos ^2\left(x\right)}{1+\cos \left(x\right)}[/tex]
[tex]\frac{-\left(\cos ^2\left(x\right)-1\right)}{1+cos(x)}[/tex]
Use the difference of squares formula:
[tex]-\frac{\left(\cos \left(x\right)+1\right)\left(\cos \left(x\right)-1\right)}{1+\cos \left(x\right)}[/tex]
Cancel out 1+cos(x):
[tex]-\left(\cos \left(x\right)-1\right)[/tex]
Remove outer bracket:
[tex]-\cos \left(x\right)+1[/tex]
[tex]1-cos(x)[/tex]

What is the equation of the graph shown?
Greetings from Brasil...
As we have a line, the function will be given by the expression:
F(X) = AX + B
where
A = ΔY/ΔX
B = where the line intersects the Y axis
Looking at the graph we have already concluded that
B = - 3
A = ΔY/ΔX
A = (5 - 3)/(4 - 3) see attached picture
A = 2
So,
F(X) = AX + B

What is the measure of the smallest angle in the figure? The figure is not drawn to scale.
Answer:
(4x-3)°=37
Step-by-step explanation:
solve for x
6x-7+90+4x-3=180
10x=180-80
10x= 100
x=10°
from the equations;
4x-3= 4(10)-3=37° and
6x-7= 6(10)-7=53
therefore the smallest angle =(4x-3) =37

5 ( y - 4)=7 (2y +1) Can someone help me out by solving for Y Thanks
5 ( y - 4 ) = 7 ( 2y + 1 )
To Find:The value of y.
Solution:5 ( y - 4 ) = 7 ( 2y + 1 )
or, 5y - 20 = 14y + 7
or, 5y - 14y = 7 + 20
or, -9y = 27
or, y = 27/-9 = -3
Answer:The value of y is -3.

simplify 3/2√3 a. √2/3 b. 2√3/3 c. 3√3/3 d. √3/2 -everything is in fraction form-
Answer:
Before A:[tex]\frac{3\sqrt{3}}{6}[/tex]
A:Already Simplified!
B:Also, Already Simplified! Can be changed to [tex]\frac{\sqrt{12}}{3}[/tex]
C:Already Simplified, yet again. Can be changed to[tex]\frac{\sqrt{27}}{3}[/tex]
D:Already Simplified.
Step-by-step explanation:
For Before A, I multiplied both denominator and numerator by square root of 3. The multiplication moved the square root to the numerator, simplifying the fraction.
The different forms of B and C are just that I multiplied the square of the first number into the square roots. This is OK because the square root of a number's square is the number itself. Therefore, you can multiply a square root by the square of the number from outside the root.
X-27=-(27-x) It’s for math 9th grade
Answer:
x - 27 = -(27 - x)
x - 27 = -27 + x
x = x
-27 is moved to the right side making it +27 and cancelling out with the -27.

[tex]3x - 5 = \frac{12 + 4x}{2} [/tex]
x = [?]
Answer:
x= 11
Step-by-step explanation:
[tex]3x - 5 = \frac{12 + 4x}{2} [/tex]
Multiply both sides by 2:
2(3x -5)= 12 +4x
Expand:
2(3x) +2(-5)= 12 +4x
6x -10= 12 +4x
Bring all x terms to 1 side, constant to the other:
6x -4x= 10 +12
2x= 22
Divide by 2 on both sides:
x= 22 ÷2
x= 11

Answer:
m<STW
Step-by-step explanation:
The m<4 is the vertex which is also T.
You can answer it with m<T but since there is lots of there, just to be more specific m<STW would be the answer.
The vertex's letter (the dot that is always in the middle of the angle where the ends of line connects) is always in the middle. You can switch the S or W if you like. it doesnt matter.

What is quadrilateral?A closed quadrilateral is a form of polygon with four sides, four vertices, and four angles. Four non-collinear points are joined to create it. Quadrilaterals' internal angles add up to a constant 360 degrees.
In the given quadrilateral,
Side AD = 8X - 1, CD = 6X + 9
And AB = 3x - 2
According to given diagram,
AD = CD
8x -1 = 6x + 9
2x = 9 + 1
2x = 10
x = 5
The length of side AB = 3x - 2 = 3 (5) - 2 = 15 - 2 = 13
The figure ABCD is a symmetrical figure,
Therefore,
AB = BC
AB = BC = 13
The required side AC = AB + BC
= 13 + 13
= 26
The length of the side AC is 26 units.

NEED HELP ASAP!!! Which of the following correctly uses absolute value to show the distance between −70 and 15? Question 6 options: 1) |−70 − 15| = |−85| = −85 units 2) |−70 + 15| = |−55| = 55 units 3) |−70 − 15| = |−85| = 85 units 4) |−70 + 15| = |−55| = −55 units
Answer:
3) |−70 − 15| = |−85| = 85 units
Step-by-step explanation:
Absolute value ignores negative values so the equation when finding the distance between −70 and 15 is 70 + 15 which equals 85.

Which expression is equivalent to 4 to the 9th power and 4 to the 0 power
a. 4 to the 8th power
b. 4 to the 0 power
C. 4 to the 7 power
d. 4 to the 9 power
Answer:
d. 4^9
Step-by-step explanation:
Question:
Which expression is equivalent to 4^9/4^0?
a. 4^8
b. 4^0
c. 4^7
d. 4^9
Solution:
By definition, a number raised to the 0 power equals 1, with the possible exception of 0^0 which according to some is undefined.
Any number divided by 1 equals the number itself.
For example, 2/1 = 2; 5/1 = 5; -20/2 = -20.
4^0 = 1
Since 4^0 = 1, then when you divide 4^9 by 4^0 you are dividing 4^9 by 1, so you get 4^9.
4^9/4^0 = 4^9/1 = 4^9
