For which of the following equations does n = 5?
I. 3n = 15
II. n2 = 25
III. 2n = 32

Answer:

63 in³

Step-by-step explanation:

Volume = l×w×h

2¼ = 9/4

8 = 8/1

3½ = 7/2

V = 9/4 × 8/1 × 7/2

= 504/8

= 63

So, the answer is 63 in³.

Answer:

Step-by-step explanation:

Let “ab” represent the digits of the number.

a ≠ 0

Value of the number = 10a+b

a+b + ab = 10a + b

a + ab = 10a

ab = 9a

b = 9

“ab” = 19, 29, 39, 49, 59, 69, 79, 89, 99

Answer: 49

Step-by-step explanation:

4x9=36

4+9=13

36+13=49

Answer: 1=same

Step-by-step explanation:1=because if you line them all up they are the same size and angle I don't know if this is correct though

Answer:

226.8%

Step-by-step explanation:

The principal is $450

Interest is 2.8%

Time is 18 months

Therefore the interest can be calculated as follows

= 450×2.8×18/100

= 22,680/100

= 226.8 %

Hence the interest is 226.8%

Answer:

V = 240 cm^3

Step-by-step explanation:

The volume formula for a cone or triangular prism such as this one is

V = (1/3)(base area)(height), which here is:

V = (1/3)(80 cm^2)(9 cm), or V = 240 cm^3

Answer:

a) Opposite sides are congruent and all interior angles are right angles, hence the quadrilateral is a rectangle

b) Opposite sides are parallel and all sides are congruent, hence the quadrilateral is a rhombus

c) All sides are congruent and all interior angles are right angles, hence the quadrilateral is a square

d) m∠AEB = 90° as the diagonals are perpendicular to each other

e) m∠EAD = 90°/2 = 45° as the diagonals of a square are bisectors of the angles at the vertices

Answer:

Step-by-step explanation:

31.5$

102ml

50 hamburgers

Step 1: Our output value is 700.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$700=100\%$700=100%​.

Step 4: Similarly, $x=42\%$x=42%​.

Step 5: This results in a pair of simple equations:

$700=100\%(1)$700=100%(1)​.

$x=42\%(2)$x=42%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{700}{x}=\frac{100\%}{42\%}$

700

x​=

100%

42%​​

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{700}=\frac{42}{100}$

x

700​=

42

100​​

Therefore, 42% of 700 is 294.

Answer:

A = 4.5

Step-by-step explanation:

Area of a triangle:

A = 1/2bh

Given:

b = 3

h = 3

Work:

A = 1/2bh

A = 1/2(3)(3)

A = 1.5(3)

A = 4.5

Answer:

q = - 13

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 6

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, q) and (x₂, y₂ ) = (0, - 7)

m = [tex]\frac{-7-q}{0+1}[/tex] = - 7 - q , then

- 7 - q = 6 ( add 7 to both sides )

- q = 13 ( multiply both sides by - 1 )

q = - 13

Answer:

q = -13?

Step-by-step explanation:

the equation is y = mx + c

m is the gradient

c is the y-intercept

where the line crosses the y axis

If 6 is the gradient then the equation is

y = 6x + c

Find c by using the coordinates given:

-7 = ( 6× 0) +c

-7 = 0 + c

c = -7

the equation is y = 6x -7

Substitute the other coordinates to find q:

y or q = (6 ×-1) - 7

q = -6 -7

q = -13

(I think that says 51...)

Basically all you do is multiply 51 by 4

Answer:

x = -5  y = -5

Step-by-step explanation:

–x + 4y = -15

     - 4y  -4y

-1(-x = -4y - 15)

x = 4y + 15

Substitute x = 4y + 15 into 3x + 5y = -40

3(4y + 15) = -40

17y + 45 = -40

      - 45   -45

17y = -85

/ 17    /17

y= -5

Substitute y = - 5 into x = 4y + 15:

x = 4(-5) + 15

x = -20 + 15

x = -5

Answer:

Part I

(-5,-5)

Part II

(3.75, 312.50)

Step-by-step explanation:

Part I

(1) 3x + 5y = -40

(2) -x + 4y = -15

solve for x in (2)

x = 15 + 4y

substitute into (1)

3(15+4y) + 5y = -40

45 +12y + 5y = -40

45 +17y = -40

17y = -85

y = -5

substitute y = -5 into (1)

3x + 5(-5) = -40

3x -25 = -40

3x = -15

x = -5

so  (-5, -5)

Part II

Studio A  

C = 125 + 50t

Studio B

C = 200 + 30t

125 + 50t = 200 + 30t

20t = 75

t = 3.75

Answer:

Sale price= $25.5

Step-by-step explanation:

Giving the following information:

The original price was $29.99, but the ball was on sale for 15% off.

To calculate the sales price, we need to use the following formula:

Sale price= original price* (1 - sales discount)

Sale price= 29.99*(1 - 0.15)

Sale price= $25.5
