Solve the inequality for y.
-3>9-6y
Simplify your answer as much as possible.
Answer:
y > 2
Step-by-step explanation:
You want the solution to the inequality ...
-3 > 9 -6y
SolutionWe can add 6y+3 to both sides. This gives ...
6y > 12
Dividing by 6 tells us the solution for y:
y > 2
__
Additional comment
We could have solved by subtracting 9 to get ...
-12 > -6y
Then dividing by -6 reverses the inequality symbol:
2 < y
We avoid the issue with negative number multiplication or division by making the y-term positive in our solution process.

Answer:
A. All sides of a rhombus are congruent, so if DK = 8, then KL = 8.
B. The diagonals of a rhombus are perpendicular to each other, so if angle KAL = 2x - 8, then we have:
2x - 8 = 90
2x = 98, so x = 49.
C. All sides of a rhombus are congruent, so if DM = 5y + 2 and DK = 3y + 6, then we have:
5y + 2 = 3y + 6
2y = 4, so y = 2, and KL = 5(2) + 2 = 12.

Test Prep What fraction is represented by the point on the number line?
The fraction represented by the point between 1 and 2 on the number line is 5/3.
If the point is between 1 and 2 on the number line, we can determine the fraction it represents by considering the distance between the point and the two adjacent integers.
The point A lies between the numbers 1 and 2, which indicates that the whole number part of the fraction is 1.
Also note that the segment between 1 and 2 is divided into 3 equal parts. A lies on the 2nd part, which implies that the fractional part is 2/3.

His height during the freefall can be modeled by the function y the height above the ground in meters and x is the time in seconds. After deploying the wingsuit, the flyer's height is given by the function y = −3x + 200. deploy the wingsuit?
The total height of the flyer at any time after deploying the wingsuit would be;
y = -3x + 200 + (-4.9t² + 420),
Now, Based on the given information, we can use the two functions to determine the height of the wingsuit flyer at a particular time.
During the freefall, the height of the flyer can be calculated using the function
y = -4.9x² + 420.
Let's say the flyer falls freely for t seconds before deploying the wingsuit.
Therefore, the height at the moment of deploying the wingsuit would be,
y = -4.9t² + 420.
After deploying the wingsuit, the height of the flyer is given by the function
y = -3x + 200.
We can combine these two functions to get the total height of the flyer at any given time after deploying the wingsuit.
So, the total height of the flyer at any time after deploying the wingsuit would be;
y = -3x + 200 + (-4.9t² + 420),

Answer:
108 sq ft
Step-by-step explanation:
The formulas are given in the bottom right.
For the triangles*, the base = 8 ft. The height = 6 feet.
Area = (bh)/2.
Area = (8*6)/2 = (48)/2 = 24 sq ft.
There are two of those identical triangles. 24+24 = 48.
(*Another way to look at this is to say that the base = 8+8 = 16. Area = (bh)/2 = (16*6)/2 = 96/2 = 48. It doesn't matter, mathematically. I can't tell if they have tried to show this as 2 triangles or one.)
For the bottom rectangle, area = length x width = 6*10 = 60 sq ft.
Add them up! 24 + 24 + 60 = 108 sq ft.
Find the surface area of the regular pyramid.
A square pyramid. The length of the base is 1 inch. The height of each triangular face is 2 inches.
Answer:
Love helping people so here's the answer :)
Step-by-step explanation:
A square pyramid has 5 faces: 1 square base and 4 triangular faces. The surface area of the pyramid is the sum of the areas of all its faces.
The area of the square base is 1 * 1 = 1 square inch.
The area of each triangular face is (1/2) * base * height = (1/2) * 1 * 2 = 1 square inch.
Since there are 4 triangular faces, the total area of the triangular faces is 4 * 1 = 4 square inches.
Therefore, the surface area of the pyramid is 1 + 4 = 5 square inches.

4. RSTU is a trapezoid because the opposite sides RS and UT are parallel.
5. RSTU is not an isosceles trapezoid because the diagonals are not congruent.
How to verify that RSTU is a trapezoid?In order to verify that RSTU is a trapezoid, we would have to determine slope of the pair of opposite sides and check whether at least one pair of opposite sides are parallel;
RU ║ ST
Slope of side RU = Slope of side ST
Slope of RU = (y₂ - y₁)/(x₂ - x₁)
Slope of RU = (1 + 3)/(5 + 3)
Slope of RU = 4/8
Slope of RU = 0.5.
Slope of RS = (y₂ - y₁)/(x₂ - x₁)
Slope of RS = (-9 + 3)/(-4 + 3)
Slope of RS = -6/-1
Slope of RS = 6.
Slope of ST = (y₂ - y₁)/(x₂ - x₁)
Slope of ST = (-2 - 1)/(10 - 5)
Slope of ST = -3/5
Slope of ST = -0.6.
Slope of UT = (y₂ - y₁)/(x₂ - x₁)
Slope of UT = (-2 + 9)/(10 + 4)
Slope of UT = 7/14
Slope of UT = 0.5.
Therefore, RSTU is a trapezoid because the opposite sides RS and UT are parallel.
Question 5.
In order to determine whether RSTU is an isosceles trapezoid, we would have to determine length of the diagonals by using the distance formula and check whether they are congruent;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance RT = √[(-2 + 3)² + (10 + 3)²]
Distance RT = √170 units.
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance US = √[(5 + 4)² + (1 + 9)²]
Distance US = √181 units.
Therefore, RSTU is not an isosceles trapezoid because the diagonals RT and US are not congruent.

The exponential model A=433.4e^0.032t describes the population, A, of a country in millions, t years after 2003. Use the model to determine when the population of the country will be 796 million.
The population of the country will be 796 million in
(Round to the nearest year as needed.)
The population of the country will be 796 million approximately in the year 2022.
To find when the population of the country will be 796 million, we can set the equation equal to 796 and solve for t:
[tex]A = 433.4e^{(0.032t)}\\796 = 433.4e^{(0.032t)}[/tex]
Divide both sides by 433.4:
[tex]e^{(0.032t)} = 1.836[/tex]
Take the natural logarithm of both sides:
[tex]ln(e^{(0.032t)}) = ln(1.836)[/tex]
0.032t = 0.605
Divide both sides by 0.032:
t = 18.91
Therefore, the population of the country will be 796 million approximately 19 years after 2003. To find the year, we add 19 to 2003:
2003 + 19 = 2022
Therefore, the population of the country will be 796 million approximately in the year 2022.

A right circular cylinder has a surface area of 112 π. If the height of the cylinder is 10, find the diameter of the base.
If the height of the cylinder is 10, the diameter of the base of the cylinder is 8 units.
A right circular cylinder has two congruent circular bases and a curved surface area. To find the diameter of the base, we need to first find the radius of the base.
Let's begin by using the given information to write an equation. The surface area of a cylinder is given by the formula:
Surface Area = 2πr² + 2πrh
where r is the radius of the base and h is the height of the cylinder.
We are given that the surface area of the cylinder is 112π and the height is 10. Substituting these values, we get:
112π = 2πr² + 2πr(10)
Simplifying the equation by dividing both sides by 2π, we get:
56 = r² + 10r
Now we have a quadratic equation in terms of r. We can solve this equation by using factoring, completing the square, or the quadratic formula. Let's use factoring:
r² + 10r - 56 = 0
(r + 14)(r - 4) = 0
The solutions are r = -14 and r = 4. Since the radius cannot be negative, the radius of the base is 4.
The diameter of the base is twice the radius, so the diameter is 8.
