2 (-3x-4) >16
Solve the inquality for X
Answer:
x < -4
Step-by-step explanation:
2(-3x - 4) > 16
-6x - 8 > 16
-6x > 16 + 8
-6x > 24
-x > 4
x < -4
Answer:
x < -4
Step-by-step explanation:
2(-3x - 4) > 16
Distribute.
-6x - 8 > 16
Add 8 to both sides.
-6x > 24
Divide by -6. When dividing by a negative, flip the sign.
x < -4.
What is an equation of the line that passes through the point (-4, -6) and is
perpendicular to the line 2x - y = 6?
22. A sandpitJis designed in the shape of a trapezium, with the dimensions shown.
If the area of the sandpit is 14 m², what will be its perimeter
Answer:
hey here is ur answer
the perimeter of a square = 4* side
4*s=14
S = 14/4
s= 7/2 or 3.5
area = side * side
area = (7/2) sq
area = 12.25sq m

Answer: 28,665 currency units
Step-by-step explanation:
Find the value of the car after 4 years using the Future value formula:
= Amount * ( 1 + rate) ^ no. of years
= 33,750 * ( 1 + (-4%))⁴
= 33,750 * 0.84934656
= 28,665.45

A swimming pool 40 feet long and 24 feet wide is surrounded by a concrete sidewalk of uniform width x. The total area enclosed by the pool and sidewalk is 1380 square feet how long is the sidewalk along the length of the pool?
Answer:
[tex]46\ \text{feet}[/tex]
Step-by-step explanation:
Let width of the sidewalk be [tex]x[/tex]
Area of the sidewalk and pool is 1380 square feet
So
[tex](40+2x)(24+2x)=1380\\\Rightarrow 960+128x+4x^2=1380\\\Rightarrow 4x^2+128x-420=0\\\Rightarrow x=\frac{-128\pm \sqrt{128^2-4\times 4\left(-420\right)}}{2\times 4}\\\Rightarrow x=3,-35[/tex]
The width of the sidewalk is 3 feet.
The length of the side walk will be [tex]40+2x=40+2\times 3=46\ \text{feet}[/tex].
A carpenter wants to make a ladder, but he want to calculate the required wood for it. The distance between each step is 1 foot Price of wood is 500 per foot calculate the price of wood as well. Example: Input: Output: Enter the length of ladder in foot: 25 Enter the width of ladder in foot: 2 Required wood in foot: 98 Cost of wood is: 49000
Answer:
Part A
The required wood for the ladder is 98 feet
Part B
The cost of the wood is 49,000
Step-by-step explanation:
Part A
The dimensions of the ladder to be made with wood are;
The distance between each step of ladder = 1 foot
The length of the ladder = 25 feet
The width of the ladder = 2 feet
The required wood = 2 × 25 feet/rail + 2 feet/steps × 24 steps = 98 feet
The required wood for the ladder = 98 feet
Part B
The cost of the wood = 500/foot × 98 feet = 49,000
The cost of the wood = 49,000

write an explicit formula for an, the nth term of the sequence 11,2,-7
Answer:
[tex]a_{n}[/tex] = 20 - 9n
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 2 - 11 = - 7 - 2 = - 9
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 11 and d = - 9 , then
[tex]a_{n}[/tex] = 11 - 9(n - 1) = 11 - 9n + 9 = 20 - 9n

Find the lateral area of this cone.
Step-by-step explanation:

lateral surface area = 10 × 26 × π
= 260π in²

plz mark my answer as brainlist if you find it useful.
Answer:
The lateral area of cone is 260π in².
Step-by-step explanation:
Given : [tex]\small\blue\bull[/tex] Height of cone = 24 in.[tex]\small\blue\bull[/tex] Radius of cone = 10 in.[tex]\begin{gathered}\end{gathered}[/tex]
To Find : [tex]\small\blue\bull[/tex] Slant height of cone [tex]\small\blue\bull[/tex] Lateral surface area of cone[tex]\begin{gathered}\end{gathered}[/tex]
Using Formulas :[tex]\star{\underline{\boxed{\sf{\purple{\ell = \sqrt{{(r)}^{2} + {(h)}^{2}}}}}}}[/tex]
[tex]\pink\star[/tex] l = slant height [tex]\pink\star[/tex] r = radius [tex]\pink\star[/tex] h = height[tex]\star{\underline{\boxed{\sf{\purple{La_{(Cone)}= \pi r\ell}}}}}[/tex]
[tex]\pink\star[/tex] La = Lateral area[tex]\pink\star[/tex] π = 3.14 [tex]\pink\star[/tex] r = radius [tex]\pink\star[/tex] l = slant height[tex]\begin{gathered}\end{gathered}[/tex]
Solution :Finding the slant height of cone by substituting the values in the formula :
[tex]\begin{gathered} \qquad{\longrightarrow{\sf{\ell = \sqrt{{(r)}^{2} + {(h)}^{2}}}}}\\\\\qquad{\longrightarrow{\sf{\ell = \sqrt{{(10)}^{2} + {(24)}^{2}}}}}\\\\\qquad{\longrightarrow{\sf{\ell = \sqrt{{(10 \times 10)} + {(24 \times 24)}}}}}\\\\\quad{\longrightarrow{\sf{\ell = \sqrt{(100)+(576)}}}}\\\\\qquad{\longrightarrow{\sf{\ell = \sqrt{100 + 576}}}}\\\\\quad{\longrightarrow{\sf{\ell = \sqrt{676}}}}\\\\\quad{\longrightarrow{\sf{\ell = 26 \: in}}}\\\\\quad\star\underline{\boxed{\sf{\pink{\ell = 26 \: in}}}} \end{gathered}[/tex]
Hence, the slant height of cone is 26 in.
[tex]\begin{gathered}\end{gathered}[/tex]
Now, finding the lateral area of cone by substituting the values in the formula :
[tex]\begin{gathered} \qquad{\longrightarrow{\sf{La_{(Cone)} = \pi r \ell}}}\\\\\qquad{\longrightarrow{\sf{La_{(Cone)} = \pi \times 10 \times 26}}}\\\\\qquad{\longrightarrow{\sf{La_{(Cone)} = \pi \times 260}}}\\\\\qquad{\longrightarrow{\sf{La_{(Cone)} = 260\pi\: {in}^{2}}}}\\\\ \qquad{\star{\underline{\boxed{\sf{\pink{La_{(Cone)} = 260\pi \: {in}^{2}}}}}}}\end{gathered}[/tex]
Therefore, the lateral area of cone is 260π in².

A running track has two semi-circular ends with radius 25m and two straights of length 87.6m as shown.
Calculate the total distance around the track rounded to 1 DP.
The total distance around the track is 332.2 meters
How to calculate the total distance?The complete question is in the attached image
The given parameters are:
Radius, r = 25 m
Length, l = 87.6 m
Start by calculating the circumference of the two semi-circular ends using:
[tex]C = 2\pi r[/tex]
So, we have:
C = 2* 3.14 * 25
Evaluate
C = 157
The total distance around the track is then calculated as:
Total = 2l + C
This gives
Total = 2 * 87.6 + 157
Evaluate
Total = 332.2
Hence, the total distance around the track is 332.2 meters

In ABC with the right angle at vertex C, sin(b)= (26)/8. What is sin(a)?
Answer:
We can use the Pythagorean theorem and properties of sines, cosines, and tangents to solve the triangle, that is, to find unknown parts in terms of known parts.
Step-by-step explanation:
Pythagorean theorem: a2 + b2 = c2.
Sines: sin A = a/c, sin B = b/c.
Cosines: cos A = b/c, cos B = a/c.
Tangents: tan A = a/b, tan B = b/a.
