Surface area measures the area of the faces. Area is a blank dimensional measurement, so it is measured in square units.
Answer:
2d or 2 dimensional is the answer i think
Step-by-step explanation:
since area is measured for 2d shapes and surface area is just finding the area of each side separately and adding it together

The cost of the hiking trip this year is 2/3of the cost of last year's trip. This year's trip cost $32
1. Write an equation that represents the cost of last years trip.
2.What was the cost of last year's trip
Answer:
The equation is ( 32/2 ) × 3 = 48.
Step-by-step explanation:
In order to find the answer, we must find one third of last years trip. To do this, we can simply divide the cost of this year's trip by two, 32/2=16.
Now if we multiply this years trip by 3, 16×3=48, we can see that the total cost of last years trip was $48.
If we'd like to turn this into a equation, it looks like this:
( 32/2 ) × 3 = 48.
please help me, I'm stuck on the second one. Also for i) i got angle ABD because angles in a semicircle measures 90 degree and OAX because the angle between the tangent and a radius is 90 degrees
Answer:
i)
DA is diameter and AX is tangent to circleYour answer is correct
m∠ABD = 90°, m∠DAX = 90°ii)
Given m∠BAX = 42° and ∠DAB is complementary with BAX ⇒
m∠DAB = 90° - 42° = 48°DC = BC ⇒ intercepted arcs are same ⇒
∠CDB = ∠BDCmDC = mCB ⇒ mDCB = ∠DAB = 48° ⇒
m∠CDB = m∠BDC = 1/2*48 = 24°iii)
∠CBA
∠CBA is supplementary with ∠ADC as opposite angles of cyclic quadrilateral (∠ADB = ∠BAX = 42°)
m∠ADC = m∠ADB + m∠CDB = 42° + 24° = 68°m∠CBA = 180° - m∠ADC = 180° - 68° = 112°∠BAE
EA║CB and AB is transversal ⇒ CBA and BAE are supplementary angles:
m∠BAE = 180° - 112° = 68°∠DCE
∠DCE = ∠DCB - ∠BCEm∠DCB = 180° - m∠DAB = 180° - 48° = 132°m∠BCE = 180° - m∠BAE = 180° - 68° = 112°∠DCE = 132° - 112° = 20°What is the value of a2+0.4a for a=0.5?

Answer:
Step-by-step explanation:
The shapes have the same height, but the base of the rectangle is half the base of the triangle. They have the same area.
:::::
area of rectangle = base × height = 4 units × 6 units = 24 units²
:::::
area of triangle = ½×base×height = ½×8 units × 6 units = 25 units²
:::::
The triangle looks bigger, but isn't. Shape affects area.

7. Find the slope of the line.
slope = rise/run
= ?/?, or ?
the slope is ___
Answer:
5
Step-by-step explanation:
You can find the slope with rise over run. Rise means up and run means moving right or left. In this case rise is 10 and run is 2. This means the fraction will look like 10/2. Simplify this to get 5 and that is your answer.
Hope this helps.
Answer:
slope 10/2=5
Step-by-step explanation:
10 rise
2 run

Solve for x, 2-x= -6-4x
a . -2/3
b.-2/5
c-8/3
d.-8/5
Answer:
-8/3
Step-by-step explanation:
2 - x = - 6 - 4x <-- Add 4x to the left side
2 + 3x = - 6 <-- Subtract 2 from the left side
3x = -8 <-- Divide 3 on both sides
x = -8/3
Answer:
x = -8/3
Step-by-step explanation:
Consolidate x terms on the right side:
2-x= -6-4x becomes 2-x + x = -6-4x + x, which in turn becomes:
2 = -6 - 3x, or 3x = -8. Then, dividing both sides by 3, we get x = -8/3

Answer:
V = 405.04
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
V = 3.14(6.1²)(10.4/3)
V = 3.14(37.21)(10.4/3)
V = 405.04

What is the equation of the trend line in the scatter plot?
Someone pls help I will pay if you get it right
Given:
The graph of a trend line.
To find:
The equation of the trend line.
Solution:
From the given graph it is clear that the trend line passes through the points (0,4) and (9,7). So, the equation of the trend line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-4=\dfrac{7-4}{9-0}(x-0)[/tex]
[tex]y-4=\dfrac{3}{9}(x)[/tex]
[tex]y=\dfrac{1}{3}x+4[/tex]
Therefore, the equation of the trend line is [tex]y=\dfrac{1}{3}x+4[/tex].
Which of the following inequalities is true?
A) -4 <-5

Loren is running in a long distance race. She is able to keep a steady pace of 10 feet per second.
Answer:
a or c Im not sure
Step-by-step explanation:
I think b though
The line which represents the speed as 10 feet per second is line B thus none of the given options are correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
As per the given,
Loren is running at speed of 10 feet per second.
Speed = distance covered/time taken
10 = distance covered/time taken
In line B, the ratio of distance covered/time taken is 10.
Thus, line B will be correct.
Hence "The line which represents the speed as 10 feet per second is line B thus none of the given options are correct".
