Answer:

2 and 1/12

Step-by-step explanation:

you need to take 2 1/2 and convert it to the common denominator of 6

so 1/2 * 3 = 3/6. and 2*6 = 12. add the 12 and 3 to get 15/6. which is equivalent to 2 1/2

so multiply 15/6 * 5/6 and get 75/36 to get or 2 and 3/36. reduce down to 2 and 1/12

Answer:

n = 3

XY = 39 ft

XZ = 39 ft

Step-by-step explanation:

     If we rotate the triangle 90° to the right we can see that the congruent angles are now on the bottom, making it the "more commonly seen isosceles triangle" we know.

     This means that the two legs will be congruent to each other, so we can set them equal and solve for n:

(9n + 12) = (15n - 6)

9n + 12 = 15n - 6

9n + 18 = 15n

18 = 6n

6n = 18

n = 3

     Now we can plug this value of n (3) into one of the expressions to solve for the legs. Since they will be the same length we only need to do one, but I will do both to make sure my work is as correct as possible:

XY

9n + 12

9(3) + 12

27 + 12 = 39

XZ

15n - 6

15(3) - 6

45 - 6 = 39

Have a nice day!

Answer:

Step-by-step explanation:

Answer: 3.5

Step-by-step explanation:

It is an intersection of a tangent and a secant.

122=9(9+2a)
144=81+18a63= 18a3.5=a

Took test as well!

The numerical value of 'a' in the secant segment of the circle is 3.5.

The secant-tangent power theorem states that "if a tangent and a secant are drawn from a common external point to a circle, then the product of the length of the secant segment and its external part is equal to the square of the length of the tangent segment."

It is expressed as:

( tangent segment )² = External part of the secant segment × Secant segment.

From the diagram:

tangent segment = 12 ft

The external part of the secant-segment = 9 ft

Secant segment = ( a + a + 9 ) = 2a + 9

To determine the value of 'a', we use the secant-tangent power theorem.

12² = 9 × ( 2a + 9 )

Solve for 'a':

144 = 18a + 81

144 - 81 = 18a

63 = 18a

a = 63/18

a = 3.5

Therefore, 'a' has a value of 3.5.

Option C) 3.5 is the correct answer.

#SPJ2

Answer:

8%

Step-by-step explanation:

percent increase = [ (difference between initial value and final value) ÷ initial value] x 100

⇒ percent increase = [ (270 - 250) ÷ 250] x 100 = 8%

Answer:

12.5

Step-by-step explanation

270 - 250 = 20

250 divided by 20 = 12.5

So therefore the percentage in the increase is 12.5

Hey there!

2n + 5 = 9

SUBTRACT 5 to BOTH SIDES

2n + 5 - 5 = 9 - 5

CANCEL out: 5 - 5 because it gives you 0

KEEP: 9 - 5 because it help solve for the n-value

NEW EQUATION: 2n = 9 - 5

SIMPLIFY IT!

2n = 4

DIVIDE 2 to BOTH SIDES

2n/2 = 4/2

CANCEL out: 2/2 because it give you 1

KEEP: 4/2 because it give you the n-value

NEW EQUATION: n = 4/2

SIMPLIFY IT!

n = 2

Therefore, your answer is: n = 2

Good luck on your assignment & enjoy your day!

Step-by-step explanation:

when a variable depends on the product or quotient of two or more variables, it is a joint variation like in our case here.

F (e.g. gravity) varies directly with the masses of 2 objects (like 2 planets) and varies inversely with the distance to or between these objects.

so, the gravity between 2 planets gets stronger the more mass the planets have, but gets weaker the more distance there is between them.

there is only one constant considered in a joint variation statement. in our case : k

Answer:

25

Explanation:

By Using Pythagoras Theorem,

h^2=p^2+b^2

or, x^2=(24)^2+7^2

or, x^2=576+49

or, x^2=625

or, x=√625

Answer:

A: 6/8 B: 1 2/8

Step-by-step explanation:

1) Count the number on spaces between the lines and then you get your denominator (bottom number of a fraction or in all)

2) Count to the line the letter is on and that will get your numerator (top number of a fraction or part of the denominator)

Note: I didn't know how to explain the numerator so...

2)   [tex]n = -3 \ \ \textsf{and} \ \ m = -4[/tex]

3)  see below

4)  A:  0 = 1

Step-by-step explanation:

Question 1

[tex]\implies 15-2x+1+4x=17[/tex]

[tex]\implies 2x+16=17[/tex]

[tex]\implies 2x=1[/tex]

[tex]\implies x=\dfrac12[/tex]

Question 2

[tex]\textsf{rearrange} \ n=m+1 :[/tex]

[tex]\implies -m=-n+1[/tex]

[tex]\textsf{add equations} \ -m=-n+1 \ \textsf{and} \ m=2n+2:\\[/tex]

[tex]\implies0=n+3[/tex]

[tex]\implies n=-3[/tex]

[tex]\textsf{substitute} \ \ n=-3 \ \ \textsf{into} \ \ m=n-1:[/tex]

[tex]\implies m=-3-1[/tex]

[tex]\implies m=-4[/tex]

Question 3

subtract the second equation from the first

divide both sides by -4

substitute found value for y into first equation

solve for x

Question 4

[tex]3j=k[/tex]

[tex]k=3j+1[/tex]

[tex]\textsf{rearrange} \ 3j=k :[/tex]

[tex]\implies -k=-3j[/tex]

[tex]\textsf{add equations}\ -k=-3j \ \ \textsf{and}\ \ k=3j+1:[/tex]

[tex]\implies 0=1[/tex]

Solution = A

Answer:

[A]

Step-by-step explanation:

Answer:

[tex]area = length \times width \\ length = \frac{area}{width } \\ length = \frac{(56 {x}^{2} + 108x + 36) {m}^{2} }{(14x + 6)m} \\ length = (4x + 6)m[/tex]

Hey there!

ASSUMING!

-3/7m = 12

IF SO!

DIVIDE -7/3 to BOTH SIDES

-7/3 * -3/7m = 12 * 7/3

CANCEL out: -7/3 * (-3/7) because it give you 1

KEEP: 12 * (-7/3) because it give you the m-value

NEW EQUATION: m = 12 * (-7/3)

SIMPLIFY IT!

m = -28

Therefore, your answer is: m = -28

(Option A)

[tex] \frac{7}{9} \times 450kg = 350kg[/tex]

[tex] \frac{2}{9} \times 450g = 100kg[/tex]

Answer & Step-by-step explanation:

In order to simplify a square root, you need to find a number that multiplied times itself equals the number in the radical. Now 7×7 is 49. Also, -7×-7 is 49 as well. But there is no number times itself that makes -49. No number times itself makes a negative number.

(You will, in time learn imaginary numbers in order to simplify this, but that can be for another day!)
