Answer:
148.877 cubic meters.
Step-by-step explanation:
To find the volume of a cube, multiply the side length by itself 3 times (x^3).
Like this,
5.3 ⋅ 5.3 ⋅ 5.3 = 148.877
148.877 is the product.
Therefore, 148.877 is the volume of this cube.

We use Pythagorean thm:
a² + b² = c²
Given:
b = 3
c = 10
Work:
a² + b² = c²
a² + 3² = 10²
a² + 9 = 100
a² = 91
[tex]\sqrt{a^2} =\sqrt{91}[/tex]
a = 9.5
Find the value of x
Step-by-step explanation:
Given Angle AOC = 90,
Angle AOB + Angle BOC = 90
[tex]3x + 46 + 14 = 90 \\ 3x + 60 = 90 \\ 3x = 90 - 60 \\ 3x = 30 \\ x = 30 \div 3 \\ = 10[/tex]
Answer:
B) 10
Step-by-step explanation:
It is given that the (m<AOC) is (90) degrees. It is also given that (<AOB) and (<BOC) compose (<AOC). Therefore, the following statement can be made;
(m<AOB) + (m<BOC) = (m<AOC)
Substitute,
(3x + 46) + (14) = (90)
Simplify,
3x + 60 = 90
Inverse operations,
3x + 60 = 90
-60 -60
3x = 30
/3 /3
x = 10

Answer:
Circumfrence: 40.21
Radius: 6.4
Step-by-step explanation:
For radius, you only have to divide the diameter (in this case 12.8) by 2 which gives us 6.4
For Circumference, plug in the radius in the formula C=2π(6.4), and that gives us 40.21

Question:
The taxi company charged a pick-up fee of $4.30 plus $1.25 per mile. The total fare was $35.55, not including the tip. How many miles was the taxi ride?
Answer:
total miles 25
Prove:
35.55-4.30=31.25
31.25/1.25= 25
OR Explained
sub 4.30 35.55 - 4.30 = 31.25
Divide 1.25 31.25/1.25 = 25
Final answer is 25
After dividing what you subtracted, you will successfully get your answer.
Answer:
25 miles is the answer
Step-by-step explanation:
how many solutions is there to the system of equations? 2x + 3y = 11 -4x - 6y = -22
Answer:
x = 4, y = -3
Step-by-step explanation:
{2x - y = 11
{x + 3y = -5
You can use the substitution method by solving for x in the second equation:
x + 3y = -5
Subtract 3y from both sides:
x = -3y - 5
Now, substitute this value for x into the first equation:
2x - y = 11
2(-3y - 5) - y = 11
Distribute:
-6y - 10 - y = 11
Add 10 to both sides:
-6y - y = 21
Combine like terms:
-7y = 21
Divide both sides by -7:
y = -3
Next, substitute this value for x into the second equation:
x + 3y = -5
x + 3(-3) = -5
Multiply:
x - 9 = -5
Add 9 to both sides:
x = 4

Answer:
x = (3-2√11)/5 ; x= (3+2√11)/5
Step-by-step explanation:
Δ/4 = (b/2)^2 - ac where b is the term that multiplies x, a is the therm that multiplies x^2 and c is the therm without x
Δ/4 = (-3)^2 - (-7*5) = 9 + 35 = 44 = 2^2 *11
x1 = (3 - √2^2 *11)/5 = (3-2√11)/5
x2 = (3+ √2^2 *11)/5 = (3+2√11)/5

Step-by-step explanation:
What is the area of this regular polygon?
Answer:
A=25√3 cm^2
Step-by-step explanation:
Since it is a regular triangle, all sides are equal to 10cm. The dotted line is a perpendicular bisector, which means that it seperates the triangle into two perfect halves. So a right triangle is formed. The bottom of the right triangle will be half of 10, and 10/2=5. So to find the missing side, use the pythagoreom theorem.
5^2+x^2=10^2
25+x^2=100
x^2=75
x= 5√3
The height of the triangle is found, so apply the formula for area:
A=1/2*5√3*10
A=25√3

PLX HELP THIS TEST IS 20 PERCENT OF MY FINALE GRADEEEEE
On Friday,
3/10
of the students at school were wearing white shirts and
5/12
of the students were wearing blue shirts.
select the fraction of students wearing either a white shirt or a blue shirt.
Answer:
43/60
3/10 x 12 = 36/120
5/12 x 10 = 50/120
50/120 + 36/120 = 86/120
Simplified we get 43/60

if f(x) = 2x +1 and g(x) = 5x-6 then what are f(-1) and g(3)
Answer: -1
Step-by-step explanation: ANSWER : -1
f(x)=3x−1=y
⇒x=3y+1
∴f−1(y)=3y+1
⇒f−1(x)=3x+1
g(x)=5x+6=z
⇒x=5z−6
g−1(z)=5z−6
⇒g−1(x)=5x−6
g−1(f−1(x))=g−1(3x+1)
=53x+1−6
=15x−17

Please help I asked this question earlier and nobody answered! :(
Answer:
B
Step-by-step explanation:
One way to tell is to put both equations into slope-intercept form. That form is usually written [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.
Solve the first equation for y.
[tex]6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2[/tex]
The slope of this line is -3, and its y-intercept is 5/2.
Solve the second equation for y.
[tex]y+3x=2\\y=-3x+2[/tex]
The slope of this line is -3 and its y-intercept is 2.
The lines are parallel because they have the same slope and different y-intercepts. There is no solution to the system.
Which graph represents a quadratic function with a negative discriminant?
Choice 1
Choice 2
Choice 3
Choice 4
Answer:
Choice 4
Step-by-step explanation:
#4 because the graph does not intersect the x-axis
The graph that represents a quadratic function with a negative discriminant is graph 4.
What is a Discriminant?The part in the formula of a quadratic equation that helps us to know the nature of the roots of a quadratic equation is known as a discriminant.
D = b2 - 4ac,
If the value of the discriminant is greater than zero then the roots of the equation are real and distinct,If the value of the discriminant is equal to zero then the roots of the equation are real and same, andIf the value of the discriminant is less than zero then the roots of the equation are imaginary.Since for the value of the discriminant to be negative, the roots of the quadratic equation should be imaginary. Also, imaginary never intersects the x-axis of the graph.
Now, in the group of the graphs the only graph that does not intersect the x-axis of the graph or have imaginary roots is graph 4.
Hence, the correct option is graph4 (Bottom Right).
