Answer: Well use the trig function sin to help.

sin(x) = 6/10 = .6

Then use inverse sign to figure out x. 

x = sin^-1(.6) = 36.87 degrees.

Because angle B is not actually 90 those 5 degrees will make angle C larger than 36.87 degrees.

Answer:

C. 7 inches x 10.5 inches

Step-by-step explanation:

7 by 10.5

7/2 = 3.5

10.5/3 = 3.5

Therefore, they each have the same dilation.

So, your answer is C. 7 inches x 10.5 inches

Is 5/5 greater than 99/100

Answers

5/5 is the same as 1 while 99/100 is only 0.99 (is less than 1).....So yes, 5/5 is greater than 99/100.
YES, 5/5 equal to ONE whole and 99/100 equals 0.99 which isn't a whole.

samuel has $1900 in the bank he wishes to increase his account to a total of $2500 by depositing $30 per week from his paycheck. write and solve an equation to find how many weeks he needs to reach his goal

Answers

Th equation is given as 2500 = 30x + 1900. Then the number of weeks he needs to reach his goal will be 20 weeks.

What is a linear equation?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will beone.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Samuel has $1900 in the bank he wishes to increase his account to a total of $2500 by depositing $30 per week from his paycheck.

Let x be the number of weeks. Then the equation will be

2500 = 30x + 1900

Simplify the equation, then we have

30x + 1900 = 2500

30x = 2500 - 1900

30x = 600

x = 600 / 30

x = 20 week

The number of weeks he needs to reach his goal will be 20 weeks.

Nautical flags are used to represent letters of alphabets. The flag for the letter O consists of a yellow right triangle and a red right triangle joined together along their hypotenuse to form a square. The joint hypotenuse of the two triangles is three inches longer than a side of the square. Find the length of a side of the flag. Round your answer to the nearest tenth.

Answers

Answer:

The length of a side of the flag is 7.2inches

Step-by-step explanation:

Let length = x

Let hypotenuse = x+3

UsingPythagoras'Theorem:

x^2 + x^2 = (x+3)^2

x^2 + x^2 = x^2 + 6x + 9

2x^2 = x^2 + 6x + 9

×^2 - 6x - 9 = 0

x =  \frac{ - b +  -  \sqrt{ {b}^(2) - 4ac } }{2a}

x=[-(-6)+sqrt.(-6)^2-4(1)(-9)]/2(1)

×=[6+sqrt.72]/2

×=7.2inches

×=[-(-6)+sqrt.(-6)^2-4(1)(-9)]/2(1)

x=[6-sqrt.72]/2

×=-1.2(rej)

(PS.sqrt is square root)

(Correctmeifiamwrong)

Answer:

7.2 in

Step-by-step explanation:

Let length of side of flag=x

Hypotenuse of right triangle=x+3

According to question information

(x+3)^2=x^2+x^2

Using Pythagoras theorem

(hypotenuse)^2=(base)^2+(perpendicular\;side)^2

x^2+6x+9=2x^2

Using identity: (x+y)^2=x^2+y^2+2xy

2x^2-x^2-6x-9=0

x^2-6x-9=0

Using quadratic formula :x=(-b\pm√(b^2-4ac))/(2a)

x=(6\pm√((-6)^2-4(1)(-9)))/(2(1))

x=(6\pm√(36+36))/(2)

x=(6\pm√(72))/(2)

x=(6\pm6\sqrt2)/(2)

x=(6+6\sqrt2)/(2)=3+3\sqrt2=7.2

x=(6-6\sqrt2)/(2)=3-3\sqrt2

x=-1.24

It is not possible because the length of side is always positive.

Hence, the side of flag=7.2 in
