The area of a rectangle is 8w + 18 square feet. The length of the rectangle is 2 feet. Use factoring to write an expression to represent the width of the rectangle.
Answer:
4w + 9
Step-by-step explanation:
Area of rectangle = length x width (or base x height, depending on how you look at it).
It is given to you that:
Area = 8w + 18
Length = 2
Let: width = x
Plug in the corresponding terms with the corresponding words:
8w + 18 = 2x
Isolate the variable, x. Divide 2 from both sides of the equation:
(8w + 18)/2 = (2x)/2
x = (8w + 18)/2
w = (8w)/2 + (18)/2
w = 4w + 9
4w + 9 is the expression that represents the width of the rectangle.

A can in the shape of a cylinder has a diameter of 10 centimeters and a height of 6 centimeters. Which measurement is closest to the total surface area of the can in square centimeters?
A) 345.58 cm2
B)293.88 cm2
C)222.36 cm2
D)449.2 cm2
The measurement 345.58 cm² is the closest to the total surface area of the can in square centimeters.
The correct option is A.
What is a cylinder?A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.
Given:
A can in the shape of a cylinder has a diameter of 10 centimeters and a height of 6 centimeters.
The surface area of the cylinder,
= 2π r h + 2π r²
= 2 (3.14)(5)(6) + 2 (3.14) (25)
= 345.4 square centimeters.
Therefore, 345.58 cm² is the closest value.

calculate the size of angle AEF
Answer:
Accuate Angel 230 digre
Answer:
90 degrees
Step-by-step explanation:
The sum of the measures of interior angles in a quadrilateral is 360 degrees. A quadrilateral is any shape that has 4 sides. ABCD is a square, and squares have 4 sides, so the sum of the angles inside of the square will be equal to 360. A square has 4 angles, each with equal measure, so to find the measure of one angle, divide 360 by 4: 360/4=90. Each angle in a square measures 90 degrees.Triangle DEF is an equilateral. This means that each side is equal, but it also means that each angle will be equal too. The sum of the measure of interior angles in a triangle is 180 degrees, and a triangle has 3 angles, therefore you can find the measure of each angle in an equilateral by dividing 180 by 3: 180/3=60. Each angle in an equilateral triangle measures 60 degrees.The measure of a straight line is always 180 degrees. CDF is a straight line, and it is made up of 3 angles:-Angle CDA
-Angle ADE
-Angle EDF
Since the measure of CDF has to be 180 degrees, the measures of angles CDA, ADE, and EDF must add up to 180.Angle CDA is an angle of a square, so it is equal to 90 degreesAngle EDF is an angle of an equilateral triangle, so it is equal to 60 degrees.The angles must add up to 180, so 90+60+ADE=180You can subtract 90 and 60 from 180 to find the measure of ADE: 180-90-60=30The question tells us that triangle ADE is isosceles. There is a theorem called base angles theorem, and it states that if two sides of a triangle are equal in length, then the two angles opposite from them will be equal in measure. Using this theorem, we can find that the measure of angle ADE is equal to the measure of AED. We already found out that ADE is 30 degrees, so AED is also 30 degrees. But the angle we are looking for is AEF:AEF is made up of angles AED and DEF, so the measures of angles AED+DEF=AEF. DEF is part of the equilateral triangle, so we know it is 60 degrees. We already found that AED is 30 degrees, so add 30 and 60 degrees: 30+60=90. AEF is 90 degrees.Pleas help me I need help really bad Which shows the given inequalities in slope-intercept

Answer:
157.08
Step-by-step explanation:
Hello There!
The first step in solving this problem is to find the formula for volume of a cylinder
To find the volume of a cylinder we use this formula
[tex]V=\pi r^2h[/tex]
Where r = radius and h = hypotenuse
we are given the height and the diameter
To convert the diameter to radius we divide the diameter by 2
5/2=2.5
so the radius is 2.5
now we plug in the values
[tex]V=\pi 2.5^28\\2.5^2=6.25\\6.25\pi =19.63495408\\19.63495408*8=157.0796327[/tex]
So the volume of the cylinder is 157.0796327
now we just round to the nearest hundredth and get that the volume of the cylinder is 157.08
[Help asap, will mark brainliest] In the figure, line a is parallel to line b.
Answer:
m <5 = 65°
m<8 = 115°
Step-by-step explanation:
m<2= m<5 = 65° (vertically opposite angles are equal)
m<5 + m<4 = 180 (co-int angles, parallel lines)
65+ m<4 =180
m<4 = 115°
Therefore
m<4=m<8 = 115° (vertically opposite angles are equal)
Answer:
m<5 = 65 degrees m<8 = 115 degrees
Step-by-step explanation:
m<2 = 65 degrees
m<2 = m<5 so
m<5 = 65 degrees
A line is 180 degrees, so
180 degrees - 65 degrees = 115 degrees
m<8 = 115 degrees

An expression is a series of number without any signs so expression would be the first one.
Inequality would be when they do a sign like > or <, etc. so it would be the 2nd one.
Equation would be when they have an equal sign which would be the 3rd one.

≥ means that it is greater than or equal to.
Any set that has all numbers over or equal to -5 would be correct, meaning that -5, -4.5, and -3 would be correct.
Hope this helps. Have a nice day.
Inequalities help us to compare two unequal expressions. The set of values makes the inequality n > -5 true is {-5, -4.5, -3}.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
As we need to find the values that will satisfy the inequality n≥-5, therefore, we need values that are greater than or equal to -5.
Hence, the set of values makes the inequality n > -5 true is {-5, -4.5, -3}.

Convert: a) 8250 g =________________kg b) 10 3/4 l =______________ ml c) 6 m 5 cm =_____________ cm d) 9 km 50 m =____________m *
Answer:
See answers below
Step-by-step explanation:
Convert: a) 8250 g =________________kg b) 10 3/4 l =______________ ml c) 6 m 5 cm =_____________ cm d) 9 km 50 m =____________m *
a) Note that 1000g = 1kg
8250g = x
1000 * x = 8250
1000x = 8250
x = 8250/1000
x = 8.25kg
b) 10 3/4 l to ml
1l = 0.001ml
10 3/4 l = x
Cross multiply
1 * x = 10 3/4 * 0.001
x = 43/4 * 0.001
x = 0.043/4
x = 0.01075ml
c) 6m 5cm to cm
Since 1m = 100cm
6m 5cm
= 6(100) + 5
= 600 + 5
= 605cm
d) 600km 50m to m
1000m = 1km
x = 9km
x = 9000m
600kn 50m
= 9000m + 50m
= 9050m
