Check out this square pyramid: Find the surface area of the square pyramid (above) using its net (below).
Answer:
12 square units
Step-by-step explanation:
Given
See attachment for net
Required
The surface area
The net has the following shapes:
1 Square: (Length =2)4 congruent triangles (Base = 2; Height = 2)So, the surface area is:
Area = Area of Square + 4 * Area of 1 Triangle
[tex]Area = 2 * 2 + 4 * \frac{1}{2} * 2 * 2[/tex]
[tex]Area = 4 + 8[/tex]
[tex]Area = 12[/tex]
If the measure of ABC is 68°, what is the measure of arc AB? (the blue line)
Which expression is equivalent to the following fraction?
Given:
The fraction is:
[tex]\dfrac{\dfrac{-2}{x}+\dfrac{5}{y}}{\dfrac{3}{y}-\dfrac{2}{x}}[/tex]
To find:
The expression that is equivalent to the given fraction.
Solution:
We have,
[tex]\dfrac{\dfrac{-2}{x}+\dfrac{5}{y}}{\dfrac{3}{y}-\dfrac{2}{x}}[/tex]
After taking LCM, we get
[tex]\dfrac{\dfrac{-2y+5x}{xy}}{\dfrac{3x-2y}{xy}}[/tex]
[tex]\dfrac{-2y+5x}{3x-2y}[/tex]
Therefore, the correct option is A.
Which inverse of the difference of 1/3 - 1/4?
Answer:
0/1
Step-by-step explanation:
Find the value of x.
Answer:
Step-by-step explanation:
When two chords intersect inside the circle, the product of their segments are equal.
BE * ED = AE * EC
x *3x = 4 *3
3x² = 12 {Divide both sides by 3}
x² = 12/3
x² = 4
x = √4
x = 2
Answer:
The value of x is 2.
Step-by-step explanation:
We know that , when the two chords are intersect inside the circle, the product of their segment are equal.
So, BE × ED = AE × EC
putting the values
x × 3x = 4 × 3
multiply the values
3 x ² = 12
divide 12 by 3
x ² = 12 / 3
x ² = 4
Taking the square root of 4
x = √4
x = 2
The value of x is 2.
What is the product?
Answer:
Step-by-step explanation:
You can do this in two steps.
4s * (5s^2 + 10s + 3) Remove the brackets
20s^3 + 40s^2 + 12 s
2(5s^2 + 10s + 3)
10s^2 + 20s + 6
Now add them
20s^3 + 40s^2 + 12s + 10s^2 + 20s + 6
Rearrange them so the like terms are together.
20s^3 + 40s^2 + 10s^2 +12s + 20s + 6
20s^3 + 50s^2 + 32s + 6

If f left parenthesis x right parenthesis equals x squared minus 3 x plus 5 , then f left parenthesis 4 right parenthesis equals
Answer:
f(4) = 9
Step-by-step explanation:
f left parenthesis x right parenthesis equals x squared minus 3 x plus 5
f(x) = x² - 3x + 5
f left parenthesis 4 right parenthesis equals
f(4) =
f(x) = x² - 3x + 5
When x = 4
f(4) = 4² - 3(4) + 5
= 16 - 12 + 5
= 9
f(4) = 9

Step-by-step explanation:
Un arco de 50 m de longitud subtiende un ángulo central θ en un círculo de 35 m de radio. Encuentre la medida de θ.
Answer:
θ = 81.89°
Step-by-step explanation:
Si tenemos un círculo de radio R, el perímetro de este círculo estará dado por:
P = 2*pi*R
donde pi = 3.14
Ahora, si en lugar de el círculo completo solo queremos la longitud de un dado arco, definido por un ángulo θ, el largo de ese arco estará dado por:
L = (θ/360°)*2*pi*R
Notar que cuando θ = 360° (es decir, el ángulo del círculo completo) el largo del arco será igual que el perímetro, lo cual deberíamos esperar.
Ahora sabemos que:
El arco tiene 50m de longitud.
El radio del círculo es 35m
queremos encontrar el valor de θ
Reemplazando esos valores en la ecuación de arriba obtenemos:
50m = (θ/360°)*2*3.14*35m
Ahora solo debemos resolver esto para θ
50m = (θ/360°)*219.8m
(50m/219.8m) = (θ/360°)
(50m/219.8m)*360° = θ = 81.89°

What is the length of leg s in the right triangle shown?
Answer:
D. 5
Step-by-step explanation:
Applying,
cos∅ = adjacent/Hypotenuse
From the diagram,
Given: ∅ = 45°, adjacent = s, hyptenuse = 5√2
Therefore,
cos45° = s/5√2
make s the subject of the equation
s = cos45°×5√2
s = (1/√2)(5√2)
s = 5
Hence the right answer is D. 5

Answer:
is the clean area the desired one (I assume, yes)?
then y <= 3x + 5
if the dotted area is the desired area, then
y >= 3x + 5
Step-by-step explanation:
the factor of x is the slope of the line expressed as y/x ratio.
clearly, the line shows that for x changing by 1 unit y changes by 3 units. so, the slope is 3/1.
that leaves us only with the 2 middle options.
for "y <=" the desired values of y for a given x must be on the line (equal) or below (smaller than the value of the line equation). that is true, if the desired area is the clear one (no dots).
so, "y >=" is true, if the dotted area is desired.

A system of equations consisting of a circle and a line is graphed. Which statements about the number of possible solutions are correct? Check all that apply.
A circle and a line always intersect, so the system can have an infinite number of solutions.
A circle and a line can intersect at one point, so the system can have one solution.
A circle and a line can intersect at three points, so the system can have three solutions.
A circle and a line can intersect twice, so the system can have two solutions.
A circle and a line do not have to intersect, so the system can have no solution.
Answer:
the solution is where the two objects intersect ...
1) A line can completely miss the circle (no solutions is possible)
2) a line can "kiss" the circle at one point (one solution)
3) note that a line can not "bend"... it can touch one side of the circle pass
through the center and touch the circle in a second spot (going out) .. two solutions...
those are the three possibility that are in the question that was posted...
three check comments are true

Complete the table for the given rule.
Rule:y= 4/1 x+1y
Answer: 2, 3, 4
Step-by-step explanation:
In the table graph provided, you will a column that has "x" as it's title. Under x, 4, 8, and 12 should listed. You figure out the answers for y by inputting the x value into the rule: y = 1/4x + 1.
For y = 1/4(4) + 1, you would multiply 1/4 by 4 and since the fours eliminate one another, you would get 1. Now, you would do 1 + 1, which equals 2. For y = 1/4(8) + 1, you would multiply 1/4 by 8 and since four and eight share the number four as their greatest common factor, four would be eliminated and eight would be reduced to 2. Now, you would do 2 + 1, which equals 3.For y = 1/4(12) + 1, you would multiply 1/4 by 12 and since four and twelve share the number four as their greatest common factor, four would be eliminated and twelve would be reduced to 3. Now, you would do 3 + 1, which equals 4.
