The perimeter of a rectangular tennis court is 228 feet. If the length of the court exceeds the twice the width by 6 feet, find its dimensions.
Answer:
Width= 36 Length=78
Step-by-step explanation:
width= w
length = 2w+6
perimeter = 2(l+w)
228=2(2w+6+w)
228 = 2(3w+6)
228=6w+12
216 =6w
w=36
width= w=36 ft
length = 2w+6 = 2(36)+6=78 feet

At the grocery store 2/5 of a pound of grapes cost $2. What is the price per pound of grapes?
Answer:
$5 per pound of grapes
Step-by-step explanation:
Because 2/5 a pound of grapes cost $2 you would add another $2 for 4/5 pound of grapes. Then, you would divide 2 by 1/2 to get $1.
So 1 pound of grapes = $5
Hope this helps!! **please give me brainliest :)
The cost of per pound of grapes is $5.
What is arithmetic operations?A number juggling activity is determined by consolidating operands with one math administrator. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations.
Both the plus sign and the minus sign can be used as operators with prefixes or infixes. Only infix operators can be used to represent all other arithmetic operators.
Given cost of 2/5 pound of grapes is $2
2/5p = 2
where p = pound
p = (2 x 5)/2
1p = 5
1 pound = $5
Therefore the 1 pound of grapes cost $5.

Answer:
X = 50
Step-by-step explanation:
Both equations TOGETHER equal 180 degrees so you write the equation:
2x + 30 + x = 180
(combine X's. Subtract 30 from both sides):
3x = 150
(divide both sides by 3)
X = 50
Use distributive property:
3(x-4)+2(x+5)
Answer:
Step-by-step explanation:
3(x - 4) + 2(x + 5) = 3*x - 3*4 + 2*x + 2*5
= 3x - 12 + 2x + 10
= 3x + 2x - 12 + 10 {Combine like terms}

[tex]\\ \sf\longmapsto WZ=12√3[/tex]
[tex]\\ \sf\longmapsto WZ=20.78[/tex]
Now
[tex]\\ \sf\longmapsto XZ^2=20.78^2+12^2[/tex]
[tex]\\ \sf\longmapsto XZ^2=431.8+144[/tex]
[tex]\\ \sf\longmapsto XZ^2=575.8[/tex]

[tex]\\ \sf\longmapsto cos\Theta=\dfrac{12}{24}[/tex]
[tex]\\ \sf\longmapsto cos\Theta=\dfrac{1}{2}[/tex]
Option C
The value of the cosine for the given triangle XZW will be ( 12 / 24 ). the correct option is C.
What are trigonometric functions?The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths. They are extensively utilized in various geosciences, including navigation, and solid mechanics.
Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.
The cosine ratio will be calculated by first calculating the perpendicular WZ.
WZ = 12 x tan60
WZ = 12 x √3
WZ = 12√3
Then calculate the hypotenuse of the triangle.
XZ² = 20.78² + 12²
XZ² = 430+ 144
XZ² = 574
XZ = 24
The cosine ratio will be calculated as:-
cosФ = Base / hypotenuse = 12 / 24.
Therefore, the value of the cosine for the given triangle XZW will be ( 12 / 24 ). the correct option is C.

3. (14 pts) Divide using either synthetic division or long division. Show how you got your
answer
(3x3 + 4x2 – 2+ 7) + (x + 2)
Divident = Divisior x Quotient + Remainder
(3x³ + 4x² - 2 + 7) = (x + 2) x (3x² - 2x) + (4x - 5)
(3x³ + 4x² - 2 + 7) = (3x³ + 4x² - 2 + 7)
What is division?A division is a process of splitting a specific amount into equal parts.
We have,
(3x³ + 4x² - 2 + 7) ÷ (x + 2)
We will divide using the long division method.
Divident = Divisior x Quotient + Remainder
Divident = (3x³ + 4x² - 2 + 7)
Divisor = x + 2
We will find the quotient and the remainder.
x + 2 ) 3x³ + 4x² - 2 + 7 ( 3x² - 2x
3x³ + 6x² [ sign is changed, 3x³ = -3x³ and 6x² = -6x²]
- 2x² - 5
- 2x² - 4x [ sign is changed, -2x² = 2x² and -4x = 4x ]
4x - 5
Quotient = 3x² - 2x
Remainder = 4x - 5
Thus,
Divident = Divisior x Quotient + Remainder
(3x³ + 4x² - 2 + 7) = (x + 2) x (3x² - 2x) + (4x - 5)
(3x³ + 4x² - 2 + 7) = (3x³ + 4x² - 2 + 7)

mph
b. At this rate, how many miles can it travel in 10 hours?
miles
Answer:
A= 560mph, B=5,600miles in 10 hours
Step-by-step explanation:
If you divide 3,360 by 6 to get the mph for part a, you’ll then multiply that by 10 to get part b.
3,360 / 6= 560

The three irrational numbers between 15 and 17 can be written as [tex]$\sqrt{231.44}\\[/tex], [tex]$\sqrt{244.57}\\[/tex], [tex]$\sqrt{277.67}\\[/tex].
What are irrational numbers?An irrational number is a number that cannot be expressed as a fraction {p/q} for any integers {p} and {q}.
Given are irrational numbers between 15 and 17.
Now, we can write -
A = 15² = 15 x 15 = 225
{A} = 225
B = 17² = 17 x 17 = 289
{B} = 289
The irrational numbers between 15 and 17 can be written as the square root of numbers between 225 and 289. So, we can write -
[tex]$\sqrt{231.44}\\[/tex]
[tex]$\sqrt{244.57}\\[/tex]
[tex]$\sqrt{277.67}\\[/tex]
Therefore, the three irrational numbers between 15 and 17 can be written as [tex]$\sqrt{231.44}\\[/tex], [tex]$\sqrt{244.57}\\[/tex], [tex]$\sqrt{277.67}\\[/tex].
