can someone please help me out with this problem ? i been trying to do this for like 2 days now and i still don’t get it .. also i need some tips on how i can remember this when im doing a different problem
Answers
Answer:
Step-by-step explanation:
the Pythagorean theorem is
c is the hypotenuse which is the side opposite of the right angle
plug the numbers into the Pythagorean theorem
[tex]x^2+(\sqrt{26})^2=13^2[/tex]
when squaring a square root, just take the number in the radical and get rid of the radical
[tex]x^2+26=169[/tex]
subtract 26 from both sides
[tex]x^2=[/tex][tex]143[/tex]
find the square root of 143
143 is prime so it can just be written as
[tex]x=\sqrt{143}[/tex]

Bryans gocket team is purchasing jersys. The company charges $250 for the onetime set-up fee and $23 for each printed jersey which expression repressents the total cost of x number for the team
Answers
Given:
The company charges $250 for the onetime set-up fee and $23 for each printed jersey.
To find:
The expression that represents the total cost of x number for the team.
Solution:
We have,
Fixed charges = $250
Additional charges = $23 per printed jersey
Let x be the number of printed jersey. Then,
Additional charges = $23x
Total chargers = Fixed charges + Additional charges
= $(250 + 23x)
Therefore, the expression for the total charges is $(250 + 23x).

Here, we want to find the volume of a cone
Mathematically, we use the formula;
V = 1/3 * pi * r^2 * h
r = 5 ft
h = 16 ft
Substituting these values;
V = 1/3 * 3.142 * 5^2 * 16

Answers
Answer:
Volume= 0.96m^3
TSA= 6.56m^2
Step-by-step explanation:
Given data
Length = 2m
Width= 80cm= 0.8m
Height= 60cm= 0.6m
Volume= L*W*H
Volume= 2*0.8*0.6
Volume= 0.96m^3
TSA=2lw+2lh+2hw
TSA= 2*2*0.8+2*2*0.6+2*0.6*0.8
TSA= 3.2+ 2.4+ 0.96
TSA= 6.56m^2

a collector purchased a rare book for $97.56 and then sold the book in an online auction for $141.82. The auction charged the collector $8.25 in fees for the use of its service. how much did the collector earn by selling the book
Answers
Answer:
$36.01
Step-by-step explanation:
141.82 - 8.25 = 133.57
133.57-97.56=36.01
The collector earned a total of $36.01 by selling the book.
What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
The collector earned $141.82 - $97.56 = $44.26 by selling the book.
To find the total amount the collector earned, we need to subtract the price they paid for the book from the price they sold it for. This gives us the profit that the collector made on the sale of the book.
However, we also need to subtract the auction fees that the collector had to pay.
The collector paid $8.25 in fees, so their total earnings from the sale of the book were :
⇒ $44.26 - $8.25
Apply the subtraction operation, and we get
⇒ $36.01.
Therefore, the collector made a total of $36.01.

Determine two pairs of polar coordinates for the point (5, -5) with 0° ≤ θ < 360°
Answers
Answer:
Step-by-step explanation:
x=5
y=-5
Hence it lies in 4th quadrant.
x=r cos θ
5=r cos θ ...(1)
y=r sin θ
-5 =r sin θ ... (2)
square and add
(5)²+(-5)²=r²(sin ²θ +cos ²θ )
r²=25+25=50
r=±5√2
dividing
tan θ=-5/5=-1=-tan 45°=tan (180-45),tan(360-45)
θ=135°,315°
so polar coordinates are (5√2,315°) and (-5√2,135°)

At a strawberry stand Luisa paid $4.50 for 2 pounds of strawberries. How much would you expect to pay for five pounds or strawberry?
Answers
Half of 4.50 is 2.25, so for one pound it would be $2.25.
To calculate five pounds, you need to add 2.25+2.25+2.25+2.25+2.25 = 11.25.
For five pounds of strawberry's, it would cost $11.25.
