Answer:
72%
Step-by-step explanation:
18/25 x 4= 72/100
=72%
Answer:
72%
Step-by-step explanation:
To convert fractions into percentages we could change to decimal and then multiply by 100 but it would be easier to just make the fraction's denominator to 100 by finding an equivalent fraction:
18/25 = 18×4/25×4
72/100

Kelly wants gummy bears. She can buy an 8 oz. bag for $0.88, a 12 oz. bag for $1.20, or a
24 oz. bag for $2.16. Which bag should Kelly buy to get the best deal?
Answer:
I believe it would be the last one (24 oz. for $2.16)
Step-by-step explanation:
The 8 oz. for $0.88 cents would cost 0.11 cents (0.88 divided by 8)
The 12 oz. for $1.20 cents would cost 0.1 cents (1.20 divided by 12)
The 24 oz. for $2.16 cents would cost 0.09 cents (2.16 divided by 24)
So since .09 is the lowest number that makes it cost less

Find the length of a rectangle with a perimeter of 148 inches and width of 36 inches.
inches
Answer:
Perimeter of rectangle = 2L + 2W
2L + 2 * 36 = 148
2L = 148 - 72
2L = 76
L = 38 inches
[tex] \\ [/tex]
To find:-Length of rectangle[tex] \\ [/tex]
Solution:-We know:-
[tex] \bigstar \boxed{ \rm Perimeter \: of \: rectangle = 2(length + width)}[/tex]
[tex] \\ [/tex]
So:-
[tex] \\ [/tex]
[tex] \dashrightarrow \sf 148 = 2(length + 36) \\ [/tex]
[tex] \\[/tex]
[tex] \dashrightarrow \sf 148 = 2(length) + 2(36) \\ [/tex]
[tex] \\ [/tex]
[tex] \dashrightarrow \sf 148 = 2(length) + 2 \times 36 \\ [/tex]
[tex] \\ [/tex]
[tex] \dashrightarrow \sf 148 = 2(length) + 72 \\ [/tex]
[tex] \\ [/tex]
[tex] \dashrightarrow \sf 148 = 2length + 72 \\ [/tex]
[tex] \\ [/tex]
[tex] \dashrightarrow \sf 148 - 72= 2length \\ [/tex]
[tex] \\ [/tex]
[tex] \dashrightarrow \sf76= 2length \\ [/tex]
[tex] \\ [/tex]
[tex] \dashrightarrow \sf 2length = 76 \\ [/tex]
[tex] \\ [/tex]
[tex] \dashrightarrow \sf length = \dfrac{76}{2} \\ [/tex]
[tex] \\ [/tex]
[tex] \dashrightarrow \sf length = \cancel \dfrac{76}{2} \\ [/tex]

What is the slope of the line that passes through the points (0, -4) and (30, – 9)?
Answer:
-1/6
Step-by-step explanation:
the slope is -1/6
A student writes the equation for a line that has a slope
of -6 and passes through the point (2, -8).
y--8) = -6(x - 2)
y-(-8) = -6x + 12
Y-(-8) + 8 = -6x + 12 + 8
y = -6x + 20

What is the slope of the line through the points (10,4)and (7,3) write your answer in simplest form
Answer:
1/3
Step-by-step explanation:
to find the slope of two points the formula is (y2-y1)/(x2-x1) so if you plug in the numbers given into that formula you get (3-4)/(7-10), then simplifying that you get (-1)/(-3) and the negatives cancle out so you get 1/3
The slope is the inclination of a line and can be calculated by the ratio of the difference of y's coordinate to x's coordinate thus the slope of the line passing through points (10,4)and (7,3) is 1/3.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines . The slope could be positive or negative.
The slope of the lines passing through points (x₁, y₁) and (x₂, y₂) is,
⇒ (y₂ - y₁)/(x₂ - x₁)
As per the given points (10,4)and (7,3)
Slope = (3 - 4)/(7 - 10)
Slope = -1/-3 = 1/3
Hence "The slope is the inclination of a line thus the slope of the line passing through points (10,4)and (7,3) is 1/3".

Question 1 Answer choices. 76° 70° 72° 79° 82°
Question 2 Answer choices. x = 7 x = 8 x = 10 x = 9 x = 12
Applying the inscribed angle theorem, we have:
1. m∠ABC = 79°
2. x = 10
What is the Inscribe Angled Theorem?The inscribed angle theorem states that the measure of an inscribed angle = 1/2(measure of intercepted arc).
Thus:
1. Find m∠ABC:
m∠ABC = 1/2(measure of arc AC) [inscribed angle theorem]
Substitute
m∠ABC = 1/2(360 - 94 - 108)
m∠ABC = 79°
2. Find the value of x:
m∠DEF = 1/2(DF) [inscribed angle theorem]
Substitute
51 = 1/2(14x - 38)
2(51) = 14x - 38
102 = 14x - 38
102 + 38 = 14x
140 = 14x
10 = x
x = 10

2. Solve the system of equations. In your final answer, include all of your work.
1) I put them in two separate brakets.
2) I solved it by equating both of them.
Answer:
1. Substitute for y in the first equation. Solve for x by completing the square. Substitute for x in the first equation to find y.
2. (x, y) = (2+2√2, -2√2) and (2-2√2, 2√2)
Step-by-step explanation:
1.The first equation is a linear equation in standard form. The second equation is a quadratic equation giving an expression for y. The system can be solved by using the second equation to substitute for y in the first equation. After the resulting equation is put in suitable form, the irrational solutions can be found by completing the square. Then the y-values can be found by substituting the x-values into either of the given equations. Usually, it is easiest to substitute into the linear equation.

2.Substituting for y in the first equation:
x +(-1/4x^2 +3) = 2
Multiplying by -4 to eliminate the fraction and make the leading coefficient 1, we have ...
-4x +x^2 -12 = -8
x^2 -4x = 4 . . . . . . add 12
x^2 -4x +4 = 8 . . . . add 4 to complete the square
(x -2)^2 = 8 . . . . . . write as a square
x -2 = ±√8 = ±2√2 . . . . take the square root
x = 2 ±2√2 . . . . . . add 2
Solving the first equation for y, we get ...
y = 2 -x
Substituting the values of x we found gives ...
y = 2 -(2 ±2√2) = ∓2√2
Solutions are ...
(x, y) = (2+2√2, -2√2) and (2-2√2, 2√2)

The thickness of a metallic tube is 1 cm and the inner diameter of the tube is 12cm. Fjnd the weight of 1 m long tube,if the density of the metal is 7.8 g/cm^3
Answer:
31.869 kg.
Step-by-Step Explanation:
Inner radius,r=12/2=6cm
thickness=1cm
so,outer radius,R=6+1=7cm
height,h=1m=100cm
volume=pi×(R^2-r^2)×h
=22/7×(7^2-6^2)×100
=22/7×(49-36)×100
=22/7×13×100
286/7×100
=28600/7
since,density=7.7gm/cm^3
also,weight=volume×density
weight=28600/7×7.7gm
=31460gm
or,31.46 kg
