Answer: area
Step-by-step explanation:
Area is solved with L * W
Volume is solved with L * W * H
Using these formulas we can see that area uses 2-dimensions, the length and the width, while volume uses 3.
Answer:
Area.
Step-by-step explanation:
2 dimentional spaces have only area, and no volume. Volume describes the amount of space within the container
What is the value of x?
To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
Answer:
x = 30°
Step-by-step explanation:
As the angle of 85° measure and the angle of (3x-5)° are vertical opposite angles, the measure of both the angles will be equal so...
(3x-5)° = 85°
3x = 85 + 5
3x = 90
x = 90/3
x = 30
So x is 30°
Let's recheck.
3x-5
(3 × 30) - 5
90 - 5
85°
Hence, the value of x = 30°
solve the following system of equations.

3x+4=13
3x=9
x=3
Input the value for x into either of the equations.

angle 3 = angle 6 = 60°
hope it helps...!!!
Answer:
m∠3 = 60°
m∠6 = 60°
Step-by-step explanation:
If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent. This is called the "Alternate Interior Angles Theorem".
As line p intersects the set of parallel lines m and n at two distinct points, then m∠3 = m∠6 and m∠4 = m∠5
Given:
m∠3 = (7x - 10)°m∠6 = (5x + 10)°As m∠3 = m∠6, then:
⇒ 7x - 10 = 5x + 10
Add 10 to both sides:
⇒ 7x - 10 + 10 = 5x + 10 + 10
⇒ 7x = 5x + 20
Subtract 5x from both sides:
⇒ 7x - 5x = 5x + 20 - 5x
⇒ 2x = 20
Divide both sides by 2:
⇒ 2x ÷ 2 = 20 ÷ 2
⇒ x = 10
Now substitute the found value of x into one of the angle expressions:
m∠3 = 7(10) - 10
= 70 - 10
= 60°
As m∠3 = m∠6, then m∠6 = 60°
Write a polynomial that represents the area of the figure below:
Answer:
2x²+2x+5
Step-by-step explanation:
Since the area of a square is a² (where a is the length of one of its sides) we'll have:
(x—1)(x—1)+(x+2)(x+2) = (x²—2x+1)+(x²+4x+4) = 2x²+2x+5
So write the answer as: 2, 2 and 5

Answer:
3.4 yards cubed
Step-by-step explanation:
Volume is length x width x height
Length 2 4/5, Width 2, Height 3/5 so 2 4/5 x 2 x 3/5
It looks like they want the answer in decimal form, so you can convert the fractions into decimals.
For the length 2 4/5, you divide the 4 by 5 to get a decimal of .8 so now it's 2.8
For the height of 3/5, you divide the 3/5 & get .6
Now it's 2.8 x 2 x .6 = 3.36 yards cubed which could get rounded up to 3.4 yards cubed
five the equation of line that is perpendicular to f(x)=-2x+1 that goes through point (0,5)
Answer:
y = [tex]\frac{1}{2}[/tex] x + 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
f(x) = - 2x + 1 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + c
the line crosses the y- axis at (0, 5 ) ⇒ c = 5
y = [tex]\frac{1}{2}[/tex] x + 5 ← equation of perpendicular line

Step-by-step explanation:
1.
that creates a right-angled triangle :
the string is the Hypotenuse (the baseline, which is the side opposite of the 90° angle).
the invisible "line" from the kite straight down to the ground is one leg. and we need that length.
and the invisible "line" on the ground between the point where Brian is standing, and the point, where the : line: coming down from the kite hits the ground, is the second leg.
the angle between both legs is 90°.
so, we use the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and the associated angles are always opposite of each other.
in our case, the Hypotenuse (the string) is opposite of 90°.
and the angle opposite of the kite height line is the designated angle of elevation at the point, where Brian is standing : 70°.
so, we have here
65/sin(90) = height/sin(70)
height = 65×sin(70)/sin(90)
sin(90) = 1
height = 65×sin(70) = 61.08002035... m
2.
another right-angled triangle.
what is not clear to me : what does "distance from plane to building" mean ?
is it really the line of sight from the plane in the air to the building in the ground ? which is the Hypotenuse of that triangle.
or is it the ground distance (from the point where the height line hits the ground to the building) ? which is also the air distance (parallel line to the ground distance up in the air with the plane).
remember, the sum of all angles in a triangle is always 180°.
per law of sine we have
height/ sin(28) = line of sight / sin(90) =
= air (or ground) distance / sin(180-28-90)
1200/sin(28) = line of sight / 1 =
= air distance / sin(62)
line of sight (if that is what we need) =
= 1200/sin(28) = 2,556.065362... m
air distance = 1200×sin(62)/sin(28) = 2,256.871758... m
3.
another right-angled triangle.
the Hypotenuse is the line of sight from the point 12 ft away in the ground to the top of the pole.
the ground distance (12 ft) is one leg.
the pole (and its height) is the second leg.
so, we have our law of sine
height/sin(53) = line of sight / sin(90) =
= ground distance / sin(180-53-90)
we need the height, so
height/sin(53) = ground distance / sin(37)
height = 12×sin(53)/sin(37) = 15.92453786... ft

Hello people ~
factorise : 5x²+16x+3
Done!
Answer:
Step-by-step explanation:
Remark
If the trinomial is going to factor, it must factor as 5 and 1 paired with 3 and 1 as both 5 and 3 do not factor any further. They are prime numbers.
Let's try this:
(5x + 1) ( 1x + 3)
Both factors must contain an + otherwise something in the given equation would be - when the factors are expanded.
It looks like this works. 5 * 3x + 1x = 16x

a car uses 9 gallons of gasoline to go 162 miles. how many gallons of gasoline will the same car use to travel 216 miles?
Answer:
[tex]12\ gallons[/tex]
Step-by-step explanation:
Step 1: Determine the unit rate
[tex]Miles / Gallons[/tex]
[tex]162\ miles / 9\ gallons[/tex]
[tex]18\ miles/gallon[/tex]
Step 2: Determine the amount of gasoline used for 216 miles
[tex]216\ miles * (gallon / 18\ miles)[/tex]
[tex]12\ gallons[/tex]
Answer: [tex]12\ gallons[/tex]
Answer:
12
Step-by-step explanation:
1. Figure out how many miles the car can go with one gallon of gasolline
162 ÷ 9 = 18
1 gallon = 18 miles
2. Figure out how many times 18 can go into 216
216 ÷ 18 = 12
12 gallons = 216 miles
*We do this because we know that every time the car drives 18 miles its uses another gallon of gas.
The car will use 12 gallons of gasoline to travel 216 miles.

Will mark brainlyest: What characteristic of the general quadratic equation below determines whether the corresponding graph has a vertical stretch? y = a(x - h)^2 + k
A: If k is positive
B: If " a " is less than zero
C: If k is negative
D: If :" a " is greater than 1
Answer:
D
Step-by-step explanation:
First of all, "k" has nothing to do with determining vertical shrink/stretch, and therefore A and C can be eliminated from the choices. A shrink occurs with a fractional "a" value, so "a" must be greater than 1 in order for a vertical stretch to occur.
Counselors at Rockport High School and Riverdale High School surveyed the graduating seniors to find out their post-high-school plans. Each student plans to attend college, attend technical school, join the military, or go right into the workforce. The results of the survey are shown in the table.
The percentage shows that they were 28% more likely to come from Riverdale High school.
How to calculate the percentage?From the information given, the percentage of those from Rockport will be:
= 25/(25 + 44) × 100.
= 25/69 × 100
= 36.23%
The percentage of those from Riverdale will be:
= 44/(25 + 44) × 100.
= 44/69 × 100
= 63.77%
Therefore, the difference will be:
= 63.77% - 36.23%
= 28% approximately.
