Answer:
Rewrite as an equation.
log
9(729)=x
Rewrite
log
9(729)=x
in exponential form using the definition of a logarithm. If
x and b
are positive real numbers and b
does not equal 1, then log b(x)=y is equivalent to by=x. 9x=729
Create expressions in the equation that all have equal bases.
(32)x=3
Rewrite
(32)x as 32x. 32x=36
Since the bases are the same, then two expressions are only equal if the exponents are also equal.
2 x 3=6
Solve for
x.x=3
The variable x
is equal to
3.3
Step-by-step explanation:
The expression not equal to 729 is 6³
What are exponents?Exponents, also known as powers, are values that show how many times to multiply a base number by itself. For example, 43 is telling you to multiply four by itself three time:4³= 4 × 4 × 4 = 64
Given here 3⁶= 3×3×3×3×3×3
= 729
6³ = 6×6×6
= 216
9³ = 9×9×9
= 729
Hence 6³ is the expression not equal to 729

first three terms of a sequence are given. Round to the nearest thousand (if necessary) 152,149,146... Find the 30th term
Answer:
65
Step-by-step explanation:
use the following equation
aₙ=a₁+(n-1)d
Where d is the common difference
n is the term
a₁ is the first term
the common difference is -3 (149-152)
this means we have
152+(30-1)*-3
Compute this and get

Find the missing side of each right triangle. Side c is the hypotenuse. Sides a and bare
the
legs. Round your answers to the nearest tenth if necessary.
a = 8.8 ft, b = 9 ft
Answer: 12.6 ft
Step-by-step explanation:
a = 8.8 ft
b = 9 ft
c = ?
Since it is a right triangle, we can use the Pythagorean Theorem to solve for missing side c, the hypotenuse.
a^2 + b^2 = c^2
(8.8)^2 + (9)^2 = c^2
158.44 = c^2
(158.44)^(1/2) = c
12.5873 = c
c = 12.6 ft (rounded to the nearest tenth)

3/10 of her allowance on a new backpack. What percent of her allowance did she spend?
Selma spent ?% of her allowance on a new backpack.
Answer:
30%
Step-by-step explanation:
Selma spent 3/10 of her allowance on a new backpack.
Hence, the percent of her allowance that she spent is calculated as:
Fraction of allowance spent on Backpack × 100
= 3/10 × 100
= 0.3/1 × 100
= 30%
Therefore, Selma spent 30% of her allowance on a new backpack.

The perimeter of the triangle below is 8x - 6.
Q
X + 1
P.
R
3x - 1
Which expression rrepresents the length of QR ?
helpppp
Answer:
QR = 4x - 6
Step-by-step explanation:
A triangle is a polygon that has three sides and three angles. There are different types of triangles such as equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.
The perimeter of a triangle is a measure of the length of the sides. It is the sum of all the length of the three sides of the triangle.
From the question:
Perimeter of triangle PQR = PQ + PR + QR
But PR = 3x - 1, PQ = x + 1, Perimeter of PQR = 8x - 6.
Therefore substituting gives:
8x - 6 = (x + 1) + (3x - 1) + QR
8x - 6 = (x + 3x + 1 - 1) + QR
8x - 6 = 4x + QR
QR = (8x - 6) - 4x
QR = 4x - 6

Answer:
Total area = 232.5 m²
Total cost to paint the area = £139.5
Step-by-step explanation:
Area of the composite figure = Area of trapezoid A + Area of rectangle B + Area of trapezoid C
Area of trapezoid A = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
Here, [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides and h is the distance between them.
Area of A = [tex]\frac{1}{2}(8+10)4[/tex]
= 36 square meter
Area of rectangle B = Length × width
= 12 × 10
= 120 m²
Area of trapezoid C = [tex]\frac{1}{2}(10+7)(9)[/tex]
= 76.5 m²
Therefore, area of the composite figure = 36 + 120 + 76.5
= 232.50 m²
Cost of paint = £6 for a tin that covers 10 m²
Therefore, total cost to paint the given figure = [tex]\frac{6}{10}\times 232.5[/tex]
= £139.5

A rectangular field has an area of 646 square feet. The width of the field is 19 feet. What is the length of he field?
If rectangular field has an area of 646 square feet. The width of the field is 19 feet. Then length of the field is 71.77 feet.
What is Area of Rectangle?The area of Rectangle is length times of width.
Given,
Area of rectangular field is 646 square feet.
width of the field is 19 feet.
We need to find the length of the field.
Area of rectangle=Length×Width
646=Length×19
Divide both sides by 19
Length=646/9
Length=71.77 feet
Hence 71.77 feet is the length of the field.

spaces are taken?
Answer:
62.5% of the parking spaces are taken.
Step-by-step explanation:
Given
Total Spaces = 3000Taken paces = 1875To determine
What percent of the parking spaces are taken?
The percentage of taken spaces of the part can be determined using the formula
% of Taken spaces = [Taken spaces / Total Spaces ] × 100
= [1875 / 3000] × 100
= 0.625 × 100
= 62.5%
Therefore, 62.5% of the parking spaces are taken.
