Answer:
A : -30(3+2w)
B : (-9-6w) ⋅ 10
E : −20(4.5 + 3w)
Step-by-step explanation:
Using distributive property:
A : -30(3+2w) = -90 - 60w : equivalent to -90 - 60w
B : (-9-6w) ⋅ 10 = -90 - 60w : equivalent to -90 - 60w
C : -3(30 - 20w) = -90 + 60w : NOT equivalent to -90 - 60w
D : (6 + 4w)×15 = 90 + 60w : NOT equivalent to -90 - 60w
E : −20(4.5 + 3w) = - 90 - 60w : equivalent to -90 - 60w
Answer:
A : -30(3+2w)
B : (-9-6w) ⋅ 10
E : −20(4.5 + 3w)
Answer:
A, B and E.
Step-by-step explanation:
We have -90-60w. Both 90 and 60 are multiples of 30, so we can apply common factor -30:
-90-60w = -30(3+2w). Then option A is correct.
Now, 90 and 60 are also multiples of 10, so we can apply common factor 10:
-90-60w = 10(-9-6w). Then option B is correct.
Now, 90 and 60 are also multiples of 3, so we can apply common factor -3:
-90-60w = -3(30+20w). Then option C is incorrect.
Now, 90 and 60 are also multiples of 15, so we can apply common factor 15:
-90-60w = 15(-6-4w). Then option D is incorrect.
Now, 90 is not a multiple of 20 but we can apply common factor obtainig a decimal number. Applying common factor -20 we have
-90-60w = -20(4.5+3w). Then option E is correct.
-3x - 3y = -30
-2x + 7y = -2
(This is elimination)
Answer:
Step-by-step explanation:
-3x - 3y = -30
-2x + 7y = -2
-3x - 3y = -30 /*(-2)
-2x + 7y = -2 /*3
6x + 6y = 60
-6x + 21y = -6
6x - 6x + 6y + 21y = 60 - 6
27y = 54
y = 2
-3x - 3y = -30
-3x - 3*2 = -30
-3x - 6 = -30

Find the surface area! :)
Answer:
A=777.54
Step-by-step explanation:
What you do is use the formula which is
a=2pirh+2pir^2.
The radius is half the diameter and the diameter is 15 so you take 15 and divide it by 2 to get 7.5.
The height is 9 m.
A=2(3.14)(7.5)(9)+2(3.14)(7.5)^2=777.54 m.
Answer:
777.15 m^2
Step-by-step explanation:
To find the surface area of a cylinder
SA = 2 pi r h + 2 pi r^2
The area of the sides Plus the area of the top and bottom
We know the diameter is 15 so the radius is 1/2 (15) = 7.5
SA = 2 * pi * (7.5) * 9 + 2 * pi * (7.5)^2
= 135pi + 112.5pi
247.5 pi
Approximating pi with 3.14
247.5 (3.14)
777.15 m^2

How many students participated in the survey

70p divided by p squared
calculate the shaded area
Answer:
116cm^2
Step-by-step explanation:
This problem is just a matter of finding the area of the large and the small circle. To find the area of the large circle, you will use the equation: A = pi*r^2 in the following manner:
A = pi*r^2
A = pi*6.5^2
A = pi*42.3
A = 133
Next, you need to subtract the smaller circle from the area to only have the shaded area. Do this like the following:
A = pi*r^2
A = pi*2.3^2
A = pi*5.29
A = 16.6
Lastly, you just need to subtract! Do this like the following:
A = 133 - 16.6 = 116.4cm^2 = 116cm^2
The area of shaded area is 116.14 cm²
Step-by-step explanation:The area of circle is given by
A=πr²Wee have 2 radii
Lets find for the radius 2.3
A = π * 2.3²
A = 16.61
Now lets find for the radius 6.5
A = π * 6.5²
A = 132.73
Now
The shaded area is 132.75 - 16.61
Shaded area = 116.14
How much will Kasey pay in Medicare if she makes $42,300 next year? $613.35 $2,678.40 $3,291.75 $4,320.00
Answer:
$613.35
Step-by-step explanation:
As 1.45% of employee's pay check goes to the Medicare, so
Total pay of Kasey in next year=$42300
Amount to be paid to medicare=1.45% of Kasey^' s pay
=42300* 1.45/100
=42300* 145/10000
= 6133500/10000
=613.35
Kasey will have to pay $613.35 to Medicare.

What is the sum of an infinite geometric series if the first term is 8 and the common ratio is 1⁄2?
A. 16
B. 8
C. 32
D. 4
Answer:
A
Step-by-step explanation:
The sum to infinity of a geometric series is
S (∞ ) = [tex]\frac{a}{1-r}[/tex] ( - 1 < r < 1 )
where a is the first term 8 and r is the common ratio, hence
S(∞ ) = [tex]\frac{8}{1-\frac{1}{2} }[/tex] = [tex]\frac{8}{\frac{1}{2} }[/tex] = 16
This sum of the infinite geometric series is 16 since the correct option is (A) 16.
Definition of infinite geometric series:The sum of infinite geometric sequences is called an infinite geometric series. There would be no final term in this series. The infinite geometric series has the general form a1+a1r+a1r2+a1r3+..., where a1 is the first term and r is the common ratio. The sum of all finite geometric series can be found.
How to find the sum of the series?In terms of the first term a1 and the common ratio r, the sum is...[tex]S =\frac {a_1}{(1-r)}[/tex]
We discover... by substituting the given numbers and performing the arithmetic...[tex]S = 8/(1 -1/2) = 16[/tex]
The total number of items in the series is 16.

Solve for x: 27/x +29=38
Answer:
x=3
Step-by-step explanation:
27/x +29=38
Multiply all terms by x and cancel:
27+29x=38x
29x+27=38x(Simplify both sides of the equation)
29x+27−38x=38x−38x(Subtract 38x from both sides)
−9x+27=0
−9x+27−27=0−27(Subtract 27 from both sides)
−9x=−27
−9x
−9
=
−27
−9
(Divide both sides by -9)
x=3
To solve for x, subtract 29 from both sides, multiply both sides by x, then divide both sides by 9 to get x = 3.
Explanation:To solve for x in the equation 27/x + 29 = 38, you first want to isolate the term with x. We can do that by subtracting 29 from both sides to get: 27/x = 38 - 29, simplified to 27/x = 9.
Next you want to get rid of the x in the denominator, which implies multiplication. You can multiply both sides of the equation by x, which will give: 27 = 9x.
To finally solve for x, divide both sides by 9 to get x = 27/9, so, x = 3.

Find the square inches
Answer:
The area of the figure is 16
Step-by-step explanation:
If you look closely there are four squares inside the figure so you get the area of one square and times it by four for the area of 16.
Answer:
16 in^2
Step-by-step explanation:
Think of the entire shape as a rectangle above and a square below. The rectangle's length and width are 6 inches and 2 inches. The side of the square is 2 inches.
area of rectangle: Ar = length * width
area of square: As = side^2
total area = Ar + As
total area = 6 in * 2 in + (2 in)^2
total area = 12 in^2 + 4 in^2
total area = 16 in^2

2X - 8 is used to represent Eight less than the product of two and a number X.
How to write the equationTo represent "Eight less than the product of two and a number X" as an expression, we can use the following equation:
2X - 8
In this expression, 2X represents the product of two and the number X, and subtracting 8 from it gives us "eight less than the product of two and a number X."
The product of two and the number X is obtained by multiplying 2 and X, which gives us 2X.
The expression "2X - 8" then subtracts 8 from the product 2X. This subtraction of 8 represents "eight less than" the product of two and a number X.

i already know that m∠GPF is 52
idk what ∠GQF
Answer:
m∠GQF=23°
Step-by-step explanation:
This is equal to 23 degrees because you know that mFG is 46°. Now, you use a theorem similar to Peripheral ∠ Th. to get 23°
Answer:
[tex]m\angle GQF=23^{\circ}[/tex]
[tex]m\angle GPF=52^{\circ}[/tex]
Step-by-step explanation:
We have been given an image of a circle and we are asked find the measure of angle GQF and measure of angle GPF.
We know that the measure of an inscribed angle is half the measure of its intercepted arc. To find the measure of angle GQF we will divide the measure of its intercepted arc (FG) by 2.
[tex]m\angle GQF=\frac{1}{2}\times 46^{\circ}[/tex]
[tex]m\angle GQF=23^{\circ}[/tex]
Therefore, the m∠GQF is 23 degrees.
We know that measure of angle formed by two intersecting secants inside a circle is half the sum of their intercepted arcs.
[tex]m\angle GPF=\frac{1}{2}\times(\text{Measure of arc FG+arc QE})[/tex]
[tex]m\angle GPF=\frac{1}{2}\times(46^{\circ}+58^{\circ})[/tex]
[tex]m\angle GPF=\frac{1}{2}\times(104^{\circ})[/tex]
[tex]m\angle GPF=52^{\circ}[/tex]
Therefore, the m∠GPF is 52 degrees.

A toy company makes rectangular sandboxes that measure 6 feet by 5 feet by 1.2 feet. A customer buys a sandbox and 40 cubic feet of sand. Did the customer buy too much or too little sand? Justify your answer
Answer:
Customer has bought too much sand
Step-by-step explanation:
Given that the dimensions (Length, Width and Height) of rectangular box are = 6,5, 1.2.
Volume of a rectangular box = Length * Width * Height
=> 6*5*1.2
=> 36 cubic feet
As mentioned, customer bought a sand box and 40 cubic feet of sand.
So,
Volume of rectangular box (R) = 36 cubic feet
Volume of Sand (S) = 40 cubic feet
From analysis
S > R
Which shows that the capacity of sandbox is 36 cubic feet and volume is 40 feet that is a little greater than desired capacity.
Therefore, customer has bought too much sand.
