If the volume of 1 block is 1 cubic unit, find the total volume of the given figure.
Answers
Answer:
16 cubic units
Step-by-step explanation:
Volume of 1 block = 1 cubic unit
No. of blocks = 16
Total volume = 1 x 16
= 16 cubic units
The total volume of the figure is 16 cubic units if the volume of 1 block is 1 cubic unit.
What is a cube?
It is defined as three-dimensional geometry that has six square faces and eight vertices.
We have:
1 block = 1 cubic unit
Total number of blocks = 16
Total volume of the figure = 1×16 = 16 cubic units
Thus, the total volume of the figure is 16 cubic units if the volume of 1 block is 1 cubic unit.

The formula is in a quadratic formula shape: [tex]y = ax^2+bx+c[/tex]
The function is negative since the value 'a' the coefficient of x^2 is negative meaning that the quadratic function is facing downards. If you don't get this explanation, take a look at the diagram I uploaded.
That means the highest point of the graph is its vertex.
But we must find where the vertex is at or the 't' value.
't' value at which vertex is = [tex]-\frac{b}{2a} =-\frac{16}{2*(-16)} =\frac{1}{2}[/tex]
Now plug this 't' value into h(t) to find the maximum height, and we will get 36 feet.

Answers
Answer:
(2, 3 )
Step-by-step explanation:
5x - 4y = - 2 → (1)
2x + 4y = 16 → (2)
add (1) and (2) term by term to eliminate y
7x + 0 = 14
7x = 14 ( divide both sides by 7 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (2)
2(2) + 4y = 16
4 + 4y = 16 ( subtract 4 from both sides )
4y = 12 ( divide both sides by 4 )
y = 3
solution is (2, 3 )
Answer:
( 2 , 3 )
Step-by-step explanation:
5x - 4y = - 2 ⇒ ( 1 )
2x + 4y = 16 ⇒ ( 2 )
( 1 ) + ( 2 )
5x - 4y + 2x + 4y = -2 + 16
7x = 14
Divide both sides by 7.
x = 2
Now let us take equation (1) to find the value of y.
5x - 4y = - 2
5 × 2 - 4y = -2
10 - 4y = -2
-4y = - 2 - 10
-4y = - 12
Divide both sides by ( -4 )
y = 3

Answers
Answer:
The volume of the prism is 72 cubic cm.
Step-by-step explanation:
This we know because a triangle with sides of 3 units, 4 units, and 5 units must be a 3–4–5 right triangle, the catheti (“legs”) of which are 3 and 4 units. So the area of the base is
3 cm. * 4 cm. / 2 = 6 square cm.
Lastly, the volume of the prism is the base area multiplied by the height:
6 square cm. * 12 cm. = 72 cubic cm.

What is the slope of a line parallel to the line whose equation is
5x – 3y = 18.
Fully simplify your answer.
Answers
Answer:
5/3, or 1.(6)
Step-by-step explanation:
find slope-intercept form
5x-3y=18
5x=3y+18
3y=5x-18
y=5/3x-6
slope is 5/3, or 1.(6)
The slope is 5/3 or 1.6.
What is a slope?It is the measure of the steepness of a line.
Given that
5x-3y = 18
Rearrange the equation
i.e. 5x-18 = 3y
y = (5/3)x - 6
The general form of the slope-intercept equation is
y = mx+c
By comparing the two equation, we get slope as
Slope of the line,m = 5/3 = 1.6
Hence, the slope of the given line is 1.6.

Step-by-step explanation:
sin²(x) + cos²(x) = 1
cos²(x) = 1 - sin²(x)
cos(x/2) = ±sqrt((1 + cos(x))/2)
in our case
sin(x) = 1/4, tan(x) > 0, so cos(x) is positive too.
sin²(x) = 1/4² = 1/16
cos²(x) = 1 - 1/16 = 15/16
cos(x) = sqrt(15)/4
cos(x/2) = sqrt((1 + sqrt(15)/4)/2) = sqrt(1/2 + sqrt(15)/8) =
= sqrt(8/16 + 2×sqrt(15)/16) =
= 1/4 × sqrt(8 + 2×sqrt(15))

Find the value of x.
Answers
Answer:
x ≈ 28°
Step-by-step explanation:
We know the hypotenuse (the longest side) and the opposite (the side opposite x) so we can use SOH:
sine x = opposite ÷ hypotenuse
Substitute in the values:
sin x = 7 ÷ 15
sin x = 0.4666...
Now we can do the inverse of sine to find x:
x = [tex]sin^{-1}[/tex](0.466..)
x = 27.818138... ≈ 28°

Step-by-step explanation:
So if you do 12 x 3 that is 36 and 36-5 is 31
so then you see if it works
31 +5 = 36
36/3 = 12
Answer:
number: 31
Let the number be x
This number is added by 5, so: x + 5
Then we divide it total by 3, so: (x + 5)/3
And this equals to 12, (x + 5)/3 = 12
Solve for unknown number:
(x + 5)/3 = 12
x + 5 = 36
x = 36 - 5
x = 31
