Answer:
2.635 x 10-3
Step-by-step explanation:
Since 0.0020635 has 3 zeros on the left of 2 then the power on 10 needs to be 3. AND since the zeros are in the left of 2 not right of 2, the power needs to be negative. So, 10^-3

A square has a perimeter of 12x 52 units. which expression represents the side length of the square in units? x 4 x 40 3x 13 3x 43
The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.
What is the perimeter of a square?The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.
[tex]P=4a[/tex]
Here, (a) is the side of the square.
A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,
[tex]P=4a\\12x +52=4a\\a=\dfrac{12x +52}{4}\\a=\dfrac{4(3x +12)}{4}\\a=3x+12[/tex]
Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

Answer:
8/8 , 12/12, 16/16
Given:
A fraction 4/4.
To find:
An equivalent fraction to a given fraction.
Solution:
A fraction equivalent to 4/4 is 8/8.
To answer this question, first of all, we should know that the equivalent fractions of a number or value are the fractions having different numerators and denominators but when simplified they are all equal to the same value or number.
There is no limit to equivalent fractions of a given number.
Now,
we have,
a fraction 4/4,
To get its equivalent fraction, we will multiply the same number in its numerator and denominator.
Let's multiply 2 in both numerator and denominator of 4/4.
We get
4x2/4x2 = 8/8
So, an equivalent fraction to 4/4 is 8/8.
In notice of this 12/12 and 16/16

The area of the asked sector is 27π units².
What is a sector of a circle?A sector of a circle is a portion or part of a circle that is composed of an arc and its two radii.
Given that a circle L, we radius 9 and a central angle of 120°, we need to find the area of the sector, which is intercepted by the central angle,
So,
The area of a sector of a circle = central angle / 360° × area of the circle,
So,
A = 120°/360° × π × 9²
= 1/3π × 81
= 27π
Hence, the area of the asked sector is 27π units².

order 130 in, 4 yd in 10 ft from greatest to least
Answer: 4 yd, 130 in, 10ft
Step-by-step explanation:
So first you turn everything into inches
130 inches is already in inches.
4 yards = 12 ft
1ft = 12 in
12 *12 = 144 in
so 4 yards is 144 inches
10 ft = 12*10
12*10 = 120
so 10ft is 120 inches
144 inches is the greatest and 120 inches is the least.

2 1/2 dozen roses cost $40.50 what is the cost of a single rose
,
Answer:
$1.35
Step-by-step explanation:
=> No. of roses in a dozen = 12
=> No. of roses in half dozen = 12/2 = 6
=> No. of roses in 2 1/2 dozen = 2(12)+6 =30
=> 30 roses costs for $40.50
=> Cost of single rose = 40.5/30 = $1.35

the next model of a sport car will cost 14.9% more than the current model. The current costs $52,000. how much will the price increase in dollars ? what will be the price of the next model
Answer:
what will be the price of the next model= 59,748
Step-by-step explanation:
7748 is 14.9% of 52000
Solution:
What is 14.9% of 52000?
Y is 14.9% of 52000
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 14.9% * 52000
Converting percent to decimal:
p = 14.9%/100 = 0.149
Y = 0.149 * 52000
Y = 7748
To find the price for the next model
7748 + 52000
=> 59,748
The dues in a neighborhood increased from $24 per month to $30 per month. Find the percent of increase.
Answer:
25%
Step-by-step explanation:
Think about it like this: $24 multiplied by how much equals $30?
This in equation form would be [tex]24x=30[/tex]
To solve for x, divide both sides by 24: [tex]x=30/24[/tex] or [tex]x=5/4[/tex]
5/4 in percentage form would be 125%, so the dues increased by 25%
Judy has made 7 t-shirts. Each day she makes 4 t-shirts. Harry had made 11 t-shirts and makes another 3 t-shirts every day. How many total t-shirts will Judy and Harry have made after 6 days?
Answer:
60
Step-by-step explanation:
So deal with Judy then Harry
JUDY:
6 days x 4 t-shirts per day = 24 t-shirts
+ 7 t-shirts made before = 31 altogether
HARRY:
6 days x 3 t-shirts per day = 18 t-shirts
+ 11 t-shirts made before = 29 altogether
JUDY & HARRY:
Now combine both
31+29=60 t-shirts

An expression has numbers, variables, and mathematical operations. The expression that represents the profit made by the organization is 5x-200.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As it is given that the profit is the difference between the revenue and cost. Therefore, the expression that represents the profit can be written as,
[tex]\rm Profit = Revenue - Cost[/tex]
[tex]= (3x^2+4x-60)-(3x^2-x+200)\\\\= 3x^2+4x-60-3x^2+x-200\\\\=5x-260[/tex]
Thus, the expression that represents the profit made by the organization is 5x-200.
