Given that 3x : 8 = 9 :2 , find the value of x .
Answer:
i hope you understand this answer
[tex]3x : 8 = 9 : 2[/tex]
[tex] \frac{3x}{8} = \frac{9}{2} [/tex]
[tex]3x × 2 = 8 × 9[/tex]
[tex]3x = \frac{8 \times 9}{2} [/tex]
[tex]3x = 4 \times 9[/tex]
[tex]x = \frac{4 \times 9}{3} [/tex]
[tex]x = 4 \times 3[/tex]
[tex]x = 12[/tex]
If f(x)=3x^2 +x-2, then f(-2)=

decide if these are equivalent ratios by simplifying. 12/27 and 20/36
Answer:
they are not equivalent
Step-by-step explanation:
12/27 reduces to 4/9 if you divide by 3
20/36 reduces to 5/9 if you divide by 4
4/9 ≠ 5/9
Step-by-step explanation:
Get your answer by reducing them:
12/27=4/9 ( in the table of 3)
20/36=5/9 ( in the table of 4)

In AQRS, the measure of ZS=90°, the measure of ZQ=64°, and RS = 16 feet. Find the length of QR to the nearest tenth of a foot.
Answer:
17.8
Step-by-step explanation:
Using the SOH CAH TOA identity
Opposite = 16
Hypotenuse = QR = x
Angle of elevation = 64 degrees
Sin64 = opp/hyp
Sin 64 = 16/x
x = 16/sin64
x = 16/0.8898
x = 17.8
Hence QR is 17.8 to the nearest tenth of a foot

Can someone help me please ? :)
Answer:
(4, 3 ) and (1.5, 8 )
Step-by-step explanation:
Given the 2 equations
2x + y = 11 → (1)
xy = 12 → (2)
Rearrange (1) expressing y in terms of x by subtracting 2x from both sides.
y = 11 - 2x → (3)
Substitute y = 11 - 2x into (2
x(11 - 2x) = 12 , that is
11x - 2x² = 12 ( subtract 12 from both sides )
11x - 2x² - 12 = 0
2x² - 11x + 12 = 0 ← in standard form
(x - 4)(2x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = 1.5
Substitute these values into (3) for corresponding values of y
x = 4 : y = 11 - 2(4) = 11 - 8 = 3 ⇒ (4, 3 )
x = 1.5 : y = 11 - 2(1.5) = 11 - 3 = 8 ⇒ (1.5, 8 )

Answer:
Volume = 120 cubic cm
Step-by-step explanation:
We would apply the formula for determining the volume of a square bases pyramid which is expressed as
Volume = 1/3 x base area x height
From the diagram,
length of square base = 6 cm
The base area = 6^2 = 36
height = 10
Thus,
Volume = 1/3 x 3/6 x 10
Volume = 120 cubic cm

Complete the function for this graph:
Answer:
The equation is:
f(x) = Ix + 3I - 2
Step-by-step explanation:
For a function like:
f(x) = Ix - kI + c
k is the x-value where the vertex is, and c is the y-value where the vertex is.
In the graph we can see that the vertex is in the point (-3, -2)
then:
x-value = -3 = k
y-value = -2 = c
Replacing those in the equation for the function:
f(x) = Ix - (-3)I - 2
f(x) = Ix + 3I - 2

Solve -3x + 12 = 2x - 18
Answer:
The value of x is 6
Step-by-step explanation:
- 3x + 12 = 2x - 18
12 + 18 = 2x + 3x
30 = 5x
5x = 30
x = 30 ÷ 5
x = 6
Thus, The value of x is 6

Find the area of this shape. (Note: the figure is NOT drawn to scale)
Answer:
The area of this shape is [tex]50cm^2[/tex].
Step-by-step explanation:
To find the area of this figure, you only need to know the area of the rectangle and the area of the triangle. The area of the rectangle would be 5 * 6 = [tex]30cm^2[/tex]. Since the length of the rectangle plus the base of the triangle is equivalent to 14, that means the base of the triangle is equal to 14 - 6 = 8 cm. The formula for the area of a triangle is [tex]\frac{1}{2} bh[/tex], the base you now know is 8 cm, and the height is 5 cm, which means the area of the triangle would be [tex]\frac{1}{2} *5*8[/tex] = [tex]\frac{1}{2} * 40[/tex] = [tex]20cm^2[/tex]. Add the area of the rectangle to the area of the triangle and you'll get the area of the entire shape, which is 30 + 20 = [tex]50cm^2[/tex].

Determine the domain of the following graph
Answer:
See below
Step-by-step explanation:
This is a piecewise function with a domain of (-4,5) and a range of [1,6]. (-4,5) means x can be between -4 and 5, but -4 and 5 can't be included (notated by the parentheses). [1,6] means y can be between 1 and 6 where 1 and 6 are both included in the range (notated by the brackets).
A dresser has a width of 6 feet, a height of 3 feet, and a depth of 2 feet. If the dresser has 6 drawers of the same size, what is the volume of the space for each drawer?
Answer:
The volume of the space for each drawer is 6 feet^3.
Step-by-step explanation:
Solve for the volume of the entire dresser.
Formula for volume of a rectangle:
Volume (v) = Length (l) × width (w) × height (h)
v = 2 × 6 × 3
v = 12 × 3
v = 36
Now divide the volume by the number of drawers.
36 ÷ 6 = 6
