What is three tenths of 90
After calculation, the fraction (three tenths) of 90 is 27.
What is the fraction (three tenths) of 90?To find fraction (three tenths) of 90, we first need to determine what three tenths of a number means. The phrase "three tenths" refers to the fraction 3/10, which can also be written as 0.3 in decimal form. Multiplying 0.3 by 90 will give us the desired value.
To perform this calculation, we can use the following steps:
Step 1: Convert the fraction to decimal form.
3/10 = 0.3
Step 2: Multiply the decimal by 90.
0.3 × 90 = 27
Therefore, three tenths of 90 is equal to 27.

A farmer wants to increase the area of his rectangular pen but keep the pen a rectangular shape He decides to add 1.3 meters of
fencing to the width of the pen but the length will remain 10.4 meters. The new area will be 81.12 square meters
Which equation can be used to determine the original width, w of the pen?
Answer:
81.12 square meters
Step-by-step explanation:
Using the equation for the area of a rectangle, the original width w of the pen is determined by 10.4(w + 1.3) = 81.12
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
Given that farmer wants to increase the area of his rectangular pen but keep the pen a rectangular shape then he decides to add 1.3 meters of
fencing to the width of the pen but the length will remain 10.4 meters.
Length = 10.4 meters.
Width w = (w + 1.3)
The new area of rectangle = 81.12 square meters
Then: Using the equation for the area of a rectangle, the original width w of the pen is determined by 10.4(w + 1.3) = 81.12

Find the domain please
the domain for a rational expression will be the values of "x" that can safely be taken without setting the denominator to 0, since if that occurs the rational becomes undefined, well we can simply set the denominator to 0 and check which values are those.

(Pre-Calculus) How do I simplify this expression? I know I'm supposed to multiply the numerator and denominator by the conjugate but I'm not sure what to do about all of the radicals in this expression.
Answer:
1+√6+i(√3+√2)

Step-by-step explanation:
i will start from multiplying the numerator and denominator by the conjugate
(1+√3 i)(1+√2 i)
(1-√2 i)(1+√2 i)-----> 1²-(√2 i)²
open brackets
1+√3i+√2i+√6i²

In an auditorium, there are 20 seats in the first row and 26 seats in the second row. The number of seats in a row continues to increase by 6 with each additional row.
(a) Write the recursive rule that represents the number of seats in each row.
(b) Write an explicit equation to model the sequence formed by the number of seats in each row. Show your work.
(c) Use the rule to determine which row has at least 100 seats.
Answer:
Step-by-step explanation:
Part A
The Recursive rule is
tn = t_(n-1) + 6
What this says in ordinary language is that the nth term = the n-1 term + 6
n≥2
Part B
The explicit equation is a little different. It makes use of the 20.
tn = 20 + (n-1)*6
Part C
20 26 32 38 .... 20 + (n - 1)* 6
Find two numbers whose sum is 16 and whose product is 55
Answer:
5 and 11
Step-by-step explanation:
To solve the problem, we take x + y = 16 and solve it for y to get y = 16 - x. Then, we replace y in x • y = 55 with 16 - x to get this:
x • (16 - x) = 55
The bottom line is that when we solved the equation we got two answers which are the two numbers that have a product of 55 and a sum of 16. The numbers are:
5
11
The two numbers that have a product of 55 and a sum of 16 are 5 and 11 as proven below:
5 • 11 = 55
5 + 11 = 16

Answer:
False

Two rays with a common endpoint can form hundreds of different angles, but are only classified as opposite rays if they form a 180° angle (aka a straight line).

Amaia purchased two blouses for $12.50 each and a skirt for $11.25. The sales tax rate is 8.5%. How much total sales tax will Amaia pay on these items
Answer:
Sales Tax: $3.08
Step-by-step explanation:
When you add the price of the items up it totals $36.25. To find the sales tax you need to take 8.5% and turn it into a decimal which is 0.085. You need to take this decimal 0.085 and multiply by $36.25 which will give you $3.08 for sales tax.

Describe one real-world example in which you would find a negative integer.
squid game answers every thing
well, a simpler example among many will be water level, on the surface of a body of water, namely lake or ocean or else, we(humans) count anything above the water as a positive integer, and anything below the water a negative one, so say a Pelican flying at 30 meters above water is +30m above, and then dives down to say 20 meters to get a fish, namely the Pelican has dived to a depth of -20m, it went from +30m to -20m, and then flies back up with its fish say 50m, so is +50m.
negative integers are always dependent on a point of reference, in the example before, the point of reference was the water level, but could be many things.

Greg trained for a triathlon for 9 hours yesterday. He ran 9 miles and then biked 135 miles. His biking speed is 12 mph faster than his running speed. What is his running speed?
The running speed is 2 mi/hr
Using the formula for calculating his speed;
Speed = distance/time
Let his running speed be "s"
If his biking speed is 12 mph faster than his running speed, then biking speed is s + 12
If he ran 9 miles and biked for 135 miles, then the required speed will be expressed as:
s + 12+s = 135/9 + 9/9
2s + 12 = 144/9
2s + 12 = 16
2s = 16 - 12
2s = 4
s = 4/2
s = 2
Hence the running speed is 2 mi/hr
