A 15-inch piece of steel is cut into three pieces so that the second plece is twice
as long as the first piece, and the third piece is three inches more than three
times the length of the first piece. Find the lengths of the pieces
What is the length of the first piece?
Answer:
3
Step-by-step explanation:
Let's represent 1st piece as a, 2nd as b, and 3rd as c.
2xa=b
a+3=c
Now replace the variables
a=3
b=6
c=6
3+6+6=15

(sinx)(tanx+cotx)
I know it =secx but I don't know how to get to it
9514 1404 393
Explanation:
It is often useful to put everything in terms of sine and cosine.
sin(x)·(tan(x) +cot(x))
= sin(x)·(sin(x)/cos(x) + cos(x)/sin(x))
= sin(x)²/cos(x) +cos(x) . . . . . . use the distributive property*
= (sin(x)² +cos(x)²)/cos(x) . . . . . combine terms over a common denominator
= 1/cos(x)
= sec(x)
_____
* The expression inside parentheses could have been combined to ...
(sin(x)² +cos(x)²)/(sin(x)·cos(x))
Then the sin/sin factors cancel, leaving the expression on line 4.

Step-by-step explanation:
Dalco Manufacturing estimates that its weekly profit, P, in hundreds of dollars, can be approximated by the
formula P = -4x² + 8x + 3, where x is the number of units produced per week, in thousands.
How many units should the company produce per week to earn the maximum profit?
Find the maximum weekly profit.
a.
b.
P = -2x^2 + 8x + 2
for maximum P, dP/dx = 0
dP/dx = -4x + 8 = 0
4x = 8
x = 2
The company should produce 2,000 units per week to earn maximum profit.
Maximum profit = -2(2)^2 + 8(2) + 2 = -8 + 16 + 2 = 10
Therefore, the maximum weekly profit is $1,000.
Write the number.
10 ones
4 tens
3 hundreds
Answer:
350
Step-by-step explanation:
It is 350 because 10 ones is 10, 4 tens is 40, and 3 hundreds is 300 if you add them up you get 350.
The required number is 350 which represents 10 ones, 4 tens
and 3 hundred.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
We have been given information as
10 ones
4 tens
3 hundred
As per the given question,
Translate the information into an algebraic expression:
It's 350 since 10 ones are 10, 4 tens are 40, and 3 hundred is 300 when added together.
⇒ 1 × 10 + 4 × 10 + 3 × 100
⇒ 10 + 40 + 300
⇒ 350
Therefore, the required number is 350 which represents 10 ones, 4 tens
and 3 hundred.

Answer:

Step-by-step explanation:
angle < EDG = 90°
5x + 4x = 90
9x = 90
x = 90/9
x = 10°
which means
5x = 50°
4x = 40°
---------------------------
sice EF and DG are parallel lines
EHD = 40°
DHG is 90°
then HGD = 50°
-----------------------------------------
ED = 64 x2 (2 sides) = 128 inches
DG = 84 x2 (2 sides) = 168 inches
total perimeter = 128 + 168 = 296 inches
and yes. theres enough room for all 3 to cuddle

the sum of 12 times a number, n, and 4 is no more than 190. What are all the possible values of the number?
Answer:
{n:n≤15.5}
Step-by-step explanation:
√First derive the inequality from interpreting the statement,thus 12n+4≤190
√Second, solve the derived inequality ( ie.make n the subject)
√Finally, you'll arrive at the answer as n≤15.5
Therefore the possible values of the variable n is all numbers less than or equal to 15.5
PROOF
For n greater than 15.5
Let's take n to be 20
Therefore from the derived inequality
12n+4≤190
12(20)+4 = 240
Here,240 is greater than 190
Since for n≥15.5 will not satisfy the inequality n≠all numbers more than 15.5

PLEASE ANSWER At the city museum, child admission is $5.70 and adult admission is $9.30 . On Saturday, 155 tickets were sold for a total sales of $1200.30 . How many adult tickets were sold that day?
Answer:
88
Step-by-step explanation:
x = # of tickets for children
y = # of adult tickets
5.7x + 9.3y = 1200.3
x + y = 155
y = 155 - x
5.7x + 9.3(155 - x) = 1200.3
5.7x + 1441.5 - 9.3x = 1200.3
-3.6x = -241.2
x = 67
we want y
x + y = 155
67 + y = 155
y = 88
