Answer:
∠ BAC ≈ 67.4°
Step-by-step explanation:
Using the sine ratio in the right triangle.
sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{12}{13}[/tex] , then
∠ A = [tex]sin^{-1}[/tex] ([tex]\frac{12}{13}[/tex] ) ≈ 67.4° ( to 1 dec. place )

80% of 90 is the same as 8/9 of 90. true or false
20% of 90 is the same as 1/5 of 90. true or false
Answers
Answer:
Both true
Step-by-step explanation: 80%*90=72. 72/90=8/9.
20%*90=18. 18/90=1/5
80% of 90 is the same as 8/9 of 90 is false.
20% of 90 is the same as 1/5 of 90 is true.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, 80% of 90 is the same as 8/9 of 90.
80% of 90 is,
= (80/100)×90.
= 8×9.
= 72.
And,
(8/9)×90.
= 8×10.
= 80.
So, 80% of 90 and 8/9 of 90 is not the same.
20% of 90 is the same as 1/5 of 90.
(20/100)×90.
= 2×9.
= 18.
And,
(1/5)×90.
= 18.
So, 20% of 90 is the same as 1/5 of 90.

if a cylinder have a side length of 13 and the radius of 10 what is the surface area
Answers
Answer:
280π units² or 879.645943 units²
Step-by-step explanation:
Let's use the formula for the surface area of a cylinder: 2πrh + 2πr² (r=radius, h=height)
Let's plug in the numbers given now since we can assume h=13 (since side length and height can be the same) while r=10.
2π(13)(10) + 2π(10)²
2π(130) + 2π(10)
260π + 20π
280π units² or 879.645943 units²

b. increase operational capital with a bank loan
c. lower fixed expenses (phone, electric, advertising)
d. lower direct costs (labor, purchasing, controlling, inventory)
Answers
Answer:
b
Step-by-step explanation:
increase operational capital with a bank loan
Increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.
What are Expenses?An expense is an item requiring an outflow of money, or any form of fortune in general, to another person or group as payment for an item, service, or other category of costs.
In the article from BusinessTown.com, the author recommends several strategies to lower the break-even point of a business, which is the point where total revenue equals total expenses. The lower the break-even point, the easier it is for a business to make a profit.
Increase operational capital with a bank loan is not a recommendation to lower the break-even point.
Instead, it suggests borrowing more money to finance operations, which can increase the break-even point and the amount of revenue needed to cover expenses.
Hence, increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.

Question 1
What value of v makes the
equation true?
5(5 + 5v) =-29 + 7v
Answers
Answer:
v = -3
Step-by-step explanation:
5 (5 + 5v) = -29 + 7v
or, 25 + 25 v = -29 + 7v
or, 25 + 29 = 7v - 25 v
or, 54 = - 18v
or, v = -54/18
or, v = -3
for checking ( putting the value of v in both sides )
5( 5 + 5 (-3))= -29 + 7 (-3)
or, 5 ( 5 - 15 ) = -29 -21
or, 5 (-10) = -50
or, -50 = - 50
the equation is true
hope it will help you ☺✌
Answer:
v = - 3
Step-by-step explanation:
Given
5(5 + 5v) = - 29 + 7v ← distribute parenthesis on left side
25 + 25v = - 29 + 7v ( subtract 7v from both sides )
25 + 18v = - 29 ( subtract 25 from both sides )
18v = - 54 ( divide both sides by 18 )
v = - 3

-2x+y=-8 and 4x-6y=-24 I need help :(
Answers
Answer: 2x+y=-8 = x=-1/2y-4
4x-6y=-24 = x =3/2y-6
Step-by-step explanation:
2x+y=-8 -- Step 1: Add -y to both sides.
2x+y+−y=−8+−y
2x=−y−8
Step 2: Divide both sides by 2.
2x/2=-y-8/2
4x-6y=-24 -- Step 1: Add 6y to both sides.
4x−6y+6y=−24+6y
4x=6y−24
Step 2: Divide both sides by 4.
4x/4=6y-24/4

Answers
Answer and Step-by-step explanation: A Line Segment is a part of a line with two endpoints and fixed length.
The length of segment JL is
JL = [tex]-1-(-10.5)[/tex]
JL = 9.5 units
And of KN:
KN = [tex]4-(-4)[/tex]
KN = 8 units
The term congruent refers to an object, form or figure that have the same shape and size.
Both segments have the same shape (a line), however not the same size. So, segments JL and KN are not congruent.

f(x)/g(x)
(x2-1)/(x-1)
x cannot equal 1 because this would render the denominator, also known as the divisor, as zero.
x can be greater than 1.
If you would like, we can factor the numerator...
x2-1
(x+1)(x-1)
FIRST...(x)(x)=x2
OUTER...(x)(-1)=-1x=-x
INNER...(1)(x)=1x=x
LAST...(1)(-1)=-1
x2-x+x-1
x2-1
So...
f(x)/g(x)=[(x+1)(x-1)]/(x-1)
(x-1) is in the numerator and denominator. It cancels...
f(x)/g(x)=(x+1)

Solve the equation for x:

for the restriction 0 < x < 2pi
Answers
Answer: x = pi
sin²x - 2cos x - 2 = 0
⇔ 1 - cos²x - 2cos x - 2 = 0
⇔ cos²x + 2cos x + 1 = 0
⇔ (cos x + 1)² = 0
⇒ cos x + 1 = 0
⇔ cos x = -1
⇒ x = pi + k2pi
because 0 ≤ x < 2pi

.75 (6/8) divided by 2= .375 (3/8)
So each soap dispenser will have 3.75 liters of soap.
