1. The sum of two consecutive even integers is 70. We can set up the equation as ( x + (x + 2) = 70 ), where ( x ) represents the first even integer. Solving for ( x ), we get ( x = 34 ) and ( x + 2 = 36 ). So, the numbers are 34 and 36.
2. Cat is 5 less than twice Dog's age, and Cat is 11 years old. Let's denote Dog's age as ( d ). The equation is ( 2d - 5 = 11 ). Solving for ( d ), we find ( d = 8 ). So, Dog's age is 8 years old.
3. The sum of three consecutive numbers is 46. Let's denote the smallest number as ( n ). The equation is ( n + (n + 1) + (n + 2) = 46 ). Solving for ( n ), we get ( n = 15 ). So, the numbers are 15, 16, and 17.
4. The equation for the sum of three consecutive even numbers totaling 198 can be written as ( n + (n + 2) + (n + 4) = 198 ), where ( n ) is the smallest even number. Solving for ( n ), we find ( n = 64 ). So, the numbers are 64, 66, and 68.
5. The equation for the sum of four consecutive numbers totaling 86 can be written as ( n + (n + 1) + (n + 2) + (n + 3) = 86 ). Solving for ( n ), we get ( n = 20 ). So, the numbers are 20, 21, 22, and 23.
6. The perimeter of a rectangle is 150 cm, and the length is 15 cm greater than the width. Let's denote the width as ( w ). The perimeter equation is ( 2(w + 15) + 2w = 150 ). Solving for ( w ), we find ( w = 30 ) and [tex]\( \text{length} = w + 15 = 45 \)[/tex]. So, the dimensions are length = 45 cm and width = 30 cm.
7. If the couch costs $825 and there's a 10% sales tax, the price before taxes can be found by dividing the price by [tex]\( 1 + \frac{\text{tax rate}}{100} \)[/tex]. So, the price before taxes is[tex]\( \frac{825}{1 + 0.10} = 750 \)[/tex].
8. Let's denote the cost of the helmet as ( h ). Since the bicycle costs 5 times as much as the helmet, we have[tex]\( \text{bike} = 5h \).[/tex] The total cost is $240, so [tex]\( \text{bike} + \text{helmet} = 240 \)[/tex]. Substituting[tex]\( \text{bike} = 5h \)[/tex], we get ( 5h + h = 240 ), which simplifies to ( 6h = 240 ). Solving for ( h ), we find ( h = 40 ). So, the helmet costs $40, and the bicycle costs [tex]\( 5 \times 40 = 200 \).[/tex]

How many sides does a regular polygon have if each exterior angle measures 30?
The number of sides that the polygon with each exterior angle measuring 30° has is 12.
What is a polygon?A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
The sum of all the exterior angles of a regular polygon is always equal to 360°. Therefore, the measure of an exterior angle for a regular polygon is given as,
[tex]\theta = \dfrac{360^o}{n}[/tex]
where n is the number of sides.
Given that the measure of the exterior angle is 30°. Therefore, the number of sides will be,
[tex]\theta = \dfrac{360^o}{n}\\\\ 30^o = \dfrac{360^o}{n}\\[/tex]

wheat grass is grown in planters that are 3 1/2 inch by 1 3/4 inch. if there is a 6x6 array of these planters with no space between them what is.the area covered by the planter ?
The area covered by the planter is 220¹/₂ in² = 220,5 in²
Further explanationTo solve the above questions, we need to recall some of the formulas as follows:
Area of Square = (Length of Side)²
Perimeter of Square = 4 × (Length of Side)
Area of Rectangle = Length × Width
Perimeter of Rectangle = 2 × ( Length + Width )
Area of Rhombus = ½ × ( Diagonal₁ + Diagonal₂ )
Perimeter of Rhombus = 4 × ( Length of Side )
Area of Kite = ½ × ( Diagonal₁ + Diagonal₂ )
Perimeter of Kite = 2 × ( Length of Side₁ + Length of Side₂ )
Let us now tackle the problem !
Given:
Length of Rectangle = L = 3¹/₂ inches
Width of Rectangle = W = 1³/₄ inches
Unknown:
Area of Plainter = A = ?
Solution:
This problem is about Area of Rectangle.
[tex]\texttt{Area of Rectangle} = \texttt{Length} \times \texttt{Width}[/tex]
[tex]\texttt{Area of Rectangle} = \texttt{Length} \times \texttt{Width}[/tex]
[tex]\texttt{Area of Rectangle} = 3\frac{1}{2} \times 1\frac{3}{4}[/tex]
[tex]\texttt{Area of Rectangle} = \boxed {6\frac{1}{8} ~ \texttt{in}^2}[/tex]
There is a 6 × 6 array of these planters with no space.
[tex]\texttt{Total Area Covered} = 6 \times 6 \times \texttt{Area of Rectangle}[/tex]
[tex]\texttt{Total Area Covered} = 6 \times 6 \times 6\frac{1}{8}[/tex]

a. 9g - 3
b. 3g - 9
c. g - 4g
d. 3g + 9
Answer:
a. 9g - 3
Step-by-step explanation:
Sal scored g number of goals this season . Ben has scored 4 times as many goals as Sal . Chun has scored 3 fewer goals than Ben. There goals can be expressed as follows
Sal's goal = g
Ben's goal = 4(g) = 4 × g = 4g
Chun's goal = 4g - 3

A section in a stained glass window is shaped like a trapezoid. The top base is 1 centimeter and the bottom base is 3.5 centimeters long. If the area of the section of glass is 8.1 square centimeters, how tall is the section?
The height of the trapezoidal section is approximately 3.6 centimeters.
Explanation:To find the height of the trapezoidal section, we can use the formula for the area of a trapezoid: A = 1/2 * (top base + bottom base) * height. In this case, the top base is 1 centimeter and the bottom base is 3.5 centimeters. We are given that the area is 8.1 square centimeters. Plugging these values into the formula:
Therefore, the height of the trapezoidal section is approximately 3.6 centimeters.
The height of the trapezoidal section of stained glass is calculated using the area formula for trapezoids. With the given measurements, the height is found to be 3.6 centimeters.
Explanation:To find the height of a trapezoid section in a stained glass window with a top base of 1 centimeter, a bottom base of 3.5 centimeters, and an area of 8.1 square centimeters, we use the formula for the area of a trapezoid, which is Area = 1/2 × (base1 + base2) × height. In this case, base1 is the top base, base2 is the bottom base, and Area is already given as 8.1 cm2.
Plugging the values into the formula gives us:
8.1 = 1/2 × (1 + 3.5) × height
8.1 = 1/2 × 4.5 × height
8.1 = 2.25 × height
To find the height, we divide both sides by 2.25:
height = 8.1 / 2.25
height = 3.6 centimeters
Thus, the height of the trapezoid section is 3.6 centimeters.

To find the perimeter of the given quadrilateral, calculate the distance between each pair of consecutive points using the distance formula and sum these distances. The perimeter is the sum of √17 + √20 + 3 + 2 which is 13.59 units.
Explanation:
The question you've asked involves finding the perimeter of a four-sided figure, known as a quadrilateral, with vertices R, S, T, and U located at (-1, 3), (-2, 7), (2, 5), and (-1, 5) respectively. To find the perimeter of this shape, we need to calculate the distance between each pair of consecutive vertices and sum these distances up.
Firstly, use the distance formula – d = √((x2 - x1)² + (y2 - y1)²) – to calculate the length of each side:
RS = √((-2 - (-1))² + (7 - 3)²) = √(1 + 16) = √17=4.12
ST = √((2 - (-2))² + (5 - 7)²) = √(16 + 4) = √20 = 4.47
TU = √((-1 - 2)² + (5 - 5)²) = √(9 + 0) = 3
UR = √((-1 - (-1))² + (3 - 5)²) = √(0 + 4) = 2
Finally, sum these distances to find the perimeter: √17 + √20 + 3 + 2 which comes out to be 13.59 units. The exact perimeter involves square roots since we're dealing with irrational distances.

Which statement describes if there is an extraneous solution to the equation √x-3 = x-5? A. there are no solutions to the equation, B. the extraneous solution is x = 7, C. the valid solutions are x = 7 and x = 4, or D. the extraneous solution is x = 4
Answer:
D. the extraneous solution is x = 4
Step-by-step explanation:
You want to know the statement that describes if there is an extraneous solution to the equation √x-3 = x-5.
SolutionA straightforward (blind) solution to the problem proceeds by squaring both sides and solving the quadratic:
x -3 = x² -10x +25
x² -11x +28 = 0
(x -7)(x -4) = 0 ⇒ x = 4 or x = 7
When you try these solutions in the original equation, you get ...
√(4 -3) = 4 -5 ⇒ 1 = -1 . . . . . x = 4 is an extraneous solution, choice D
√(7 -3) = 7 -5 ⇒ 2 = 2 . . . . . x = 7 is the solution
DomainThe square root function is only defined for non-negative values, so the left side of the equation is only defined for x ≥ 3.
The left side of the equation produces non-negative values. The right side of the equation will have non-negative values only for x ≥ 5.
Considering the domain of the equation is x ≥ 5, we know that x = 4 cannot be a solution. It can be ignored. This value only arises because squaring the radical allows values of x that require the root to be negative.
__
Additional comment
The attached graph shows the only solution is x=7, the value that makes the difference between the sides of the equation be zero. We find it useful to write radical equations in the form f(x) = 0, making the x-intercepts of the graph of f(x) be the solution(s). The graphing calculator does not graph the function where it is undefined, so the domain restrictions are automatically accommodated.
