I need the answer for this equation

Answers

Answer 1

Answer:

10 is the answer

Step-by-step explanation:

Let squares be x, triangles be y and circle be z

Now,

x³ = 27

so, x = 3

Now,

x * y * y * y = 24

or, 3 * y³ = 24

or, y³ = 24/3

so, y³ = 8

so, y = 2

Again,

x * y * z² = 96

or, 3 * 2 * z² = 96

or, 6z² = 96

or, z² = 96/6

so, z² = 16

so, z = 4

Now,

z + x*y = 4 + 3*2 = 4 + 6 = 10

Answer 2

it should be 55, 27 divided by 3 is 9, 24-9 is 15, 15 divided by 3 is 5, 96-9-5=82, 82 divided by 2 is 41 so 41+5+9=55

Increase £16470.45 by 13.5%

Answers

Answer: 18693.51075= £18,693.51

Step-by-step explanation:

16470.45/100=164.7045

164.7045x13.5=2223.51075

2223.51075=16470.45=18693.51075

18693.51075= £18,693.51

The increment of £16470.45 by 13.5% is £18693.96.

PercentageWhat is percentage?

A part per hundred is what the percentage denotes. The symbol '%' is used to symbolise it. Example percentages include: 10% is represented as the fraction 1/10.

Calculate the percentage:

The amount is given as £16470.45.

As, the amount is increased by 13.5%.

Thus 13.5% of £16470.45 will be calculated as,

= 16470.45 ×(13.5/100)

= 2223.51

Thus, the 13.5% of the amount will be £2223.51

Calculate the increment of the amount:

As, the incremented amount is calculated as £2223.51.

The amount after the increment will be,

= 16470.45 + 2223.51

= 18693.96

Therefore, the total amount after the increment of 13.5% is £18693.96.

A cable 52.6 meters long is cut into two pieces so that one piece is 27.2 meters longer than the other. Find the length of each piece of cable.

Type the product of the lengths of the two pieces, rounded to the nearest tenth.

Answers

Answer:

Piece1: 12.7 meters

Piece2: 39.9 meters

Product of the two to nearest tenth: 506.7

Step-by-step explanation:

Piece1: x

Piece2: x + 27.2

x + x + 27.2 = 52.6

2x + 27.2 = 52.6

2x = 25.4

x = 12.7

Piece1: 12.7

Piece2: 12.7 + 27.2 = 39.9

Product of the two pieces:

12.7 * 39.9 = 506.73

After a shopping spree at Target, John realized he spent three times more money than his brother Mike. They spent a total of $160. If you choose x to represent the
amount of money that Mike spent, what choice below would represent the amount of money that John spent?

Answers

Answer:

John spent around $53

Step-by-step explanation:

The equation is 3x=160

Since the "x" is already by itself on one side, divide 160 by 3

160÷3=53.333⇒

Now if that's not the way IT CAN ALSO BE:

30x3+70=160! That means John spent $90

Can someone rate my answer and tell me how i did pls /I measured my door in my room. The height was 74 inches and the length was 35 inches so to find the area you would multiply 74 by 35

Answers

Answer:

Partially correct!!

Step-by-step explanation:

To find the area, you only need to multiply LENGTH x WIDTH. So, you did it correctly.

Not the height and the length. You wouldn't need the height to calculate area! Good try though! If you're still stuck next time you measure a door, look up how to calculate area if you are ever stuck.

what is an equation of the line that passes through the points (-4, -3) (7, 8)

Answers

Answer:

y = x + 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

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

with (x₁, y₁ ) = (- 4, - 3 ) and (x₂, y₂ ) = (7, 8 )

m = [tex]\frac{8-(-3)}{7-(-4)}[/tex] = [tex]\frac{8+3}{7+4}[/tex] = [tex]\frac{11}{11}[/tex] = 1 , then

y = x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (7, 8 ) , then

8 = 7 + c ⇒ c = 8 - 7 = 1

y = x + 1 ← equation of line

. In a soccer league, each of the n participating teams plays every other team twice during the season. If in the next season the league increases the number of teams by two, then there would be 27.5% more matches played. Find

Answers

The number of teams and matches in the soccer league illustrates permutation and combination

There are 12 teams in the soccer league in the first season

How to determine the number of teams

The number of teams in the soccer league is given as n.

So, the total number of matches played in a season is:

Matches = n(n-1)/2

When the number of teams increases by 2, we have:

Matches = (n + 2)(n + 2 -1)/2

Also, the number of matches increases by 27.5%.

So, we have:

Matches = n(n-1)/2 * (1 + 27.5%)

Equate both equations

[tex]\frac{(n + 2)(n + 2 -1)}{2} = \frac{n(n-1)}{2} * (1 + 27.5\%)[/tex]

Simplify

[tex]\frac{(n + 2)(n + 1)}{2} = \frac{n(n-1)}{2} * (1.275)[/tex]

Multiply through by 2

[tex](n + 2)(n + 1) = n(n-1) * (1.275)[/tex]

Expand

[tex]n^2 + 3n + 2 = 1.275n^2 - 1.275[/tex]

Collect like terms

[tex]n^2 -1.275n^2+ 3n + 2 +1.275 = 0[/tex]

Evaluate the like terms

[tex]-0.275n^2+ 3n + 3.275 = 0[/tex]

Using a graphing calculator, we have:

n = -1 or n = 11.909

n cannot be negative.

So, we have:

n = 11.909

Approximate

n = 12

Hence, there are 12 teams in the soccer league in the first season

How do you find x????????!

Answers

Answer: x = 112

===========================================================

Work Shown:

Let's make each of those unlabeled angles be angle y.

We have two copies of y, since the arcs are the same (meaning they are congruent angles) and 44 as well.

The three interior angles of any triangle add to 180

44+y+y = 180

2y+44 = 180

2y = 180-44 ... subtracting 44 from both sides

2y = 136

y = 136/2 ... divide both sides by 2

y = 68

Once we know y, we can find x

x+y = 180 ... since the adjacent angles form a straight line

x+68 = 180

x = 180-68 ... subtract 68 from both sides

x = 112

What is the image of the point (8,-6) after a rotation of 180° counterclockwise
about the origin?

Answers

Answer:

(-8,6)

Step-by-step explanation:

rotating 180 degrees: x and y coordinates change signs

After rotating the point(8, -6) 180 counterclockwise it will become (-8,6).

What are the coordinates of a point?

A point's coordinates are a pair of integers that pinpoint where it is precisely on a two-dimensional plane. Remember that the x and y axes are two axes that are at right angles to one another and make up the coordinate plane. A particular point's coordinates show how far along each axis it is situated.

Given a point (8,-6) after rotating it counterclockwise 180°. A' is formed when our point A(x,y) rotates 180 degrees counterclockwise around the origin (-x,-y). As a consequence, we just make both x and y negative.

Therefore new coordinates of the point will be (-8,6). For better understanding, I am attaching two graphs.
