d) 4.33 x 10^4
Can U pls help me on this question
Answer:
25
Step-by-step explanation:
they are alternative exterior angles meaning they are equal.so you can solve by doing
7x-40=5x+10
isolate the terms by adding like terms. ( add 40 from the left side of the equation to the right.)
so it would look like this.
7x=5x+10+40. (the 40 was negative on the left side so you have to do the inverse to move it) do the same with the 5x.
now you have
2x=50. divide 50 by 2 to get your final answer .

Find the GCF of the monomials 6d3, 27d2
Answer:
3d^2
Step-by-step explanation:
First, find the GCF of 6 and 27, which is 3.
Factors of 6: 1, 2, 3, 6
Factors of 27: 1, 3, 9, 27
Then, find the greatest value of the variable d^3 and d^2, which is d^2. Since this is a variable, we just need to take out the highest degree accompanying the variable.
27(d^2)
6d(d^2)
Combine both of your findings to get 3d^2.

Answer:
∠ 1 = 37°
Step-by-step explanation:
(9x - 8) and (6x + 7) are corresponding angles and are congruent, then
9x - 8 = 6x + 7 ( subtract 6x from both sides )
3x - 8 = 7 ( add 8 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
Then
∠ 1 = 6x + 7 = 6(5) + 7 = 30 + 7 = 37°

Which expression best represents the value of it? * The local pizza place has placed a new circular sign above the restaurant. The circumference of the sign is 37.68 feet, and the diameter is 12 feet. Which expression best represents the value of pi?
A.37.68/6
B.37.68/12
C.12/37.68
D.6/37.68
Answer:
B
Step-by-step explanation:
The circumference of a circle can be described as the linear distance round the circle
The circumference of a circle = 2πr or πD
π = 3.14
r = radius
d = diameter
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
π = circumference / 2r or circumference / D
37.68 / 12

The rectangle TV's width is determined by the formula W = 64.3 inches.
What is the diagonal of a rectangle?The formula determines a rectangle's diagonal.
From the Pythagoras Theorem , The hypotenuse² = base² + height² , and
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
Given data ,
Let D represent the diagonal of the rectangular TV.
D is now equal to 90 inches.
Let the TV's rectangle size be 63 inches.
Let W be the TV's rectangular width.
And , Diagonal of a Rectangle = √ ( Length )² + ( Width )²
D² = L² + W²
90² = 63² + W²
Subtracting 63² on both sides of the equation , we get
W² = 90² - 63²
On simplifying the equation , we get
W² = 4131
Taking square roots , we get
W = √4131 inches
W = 64.3 inches
Thus , W is equal to 64.3 inches.
Hence, the rectangular TV is 64.3 inches wide.
