Answer:

mike's estimated the difference was 72, the actual difference is 72.74

hoped this helped!

Answer:

Mike estimated the difference to be 72
The actual difference is 72.74

Step-by-step explanation:

When mike rounded, 79.44 became 79 and 6.7 became 7

79.44 rounds to 79 because 0.44 is less then 0.5
6.7 rounds to 7 because 0.7 is greater then 0.5
so 79 - 7 = 72

The actual difference is 79.44 - 6.7 = 72.74
                           
 79.44
-   6.70
------------

  72.74

The value close to zero gives lower absolute value and value far from zero gives higher absolute value.

Absolute value describes a number's distance from zero on the number line without taking direction into account. A number's absolute value is never negative.

Given:

As, the temperature is below zero it is represented by negative numbers.

So, as the value gets closer to zero then the lower the absolute value.

and, if the value is far from zero then the higher the absolute value.

Answer:

w= 8,1

Step by step:

w/9= 0.9

the 9, instead of dividing in becomes a multiplication, which you will multiply with 0.9, which is the answer

which goes like...

w/9 = 0.9  

w = 0.9 x 9 = 8,1

And then we check it if it's true

8,1 / 9 = 0.9

And it is

Answer: 306

Step-by-step explanation:

First you have to find the surface are for each shape using its dimensions. Using each shape' surface are you would multiply it with the one with the same dimensions. Then add all of the surface areas together.

A=bh- rectangle with 12ft base and 4 ft height

12·4=48

48·2=96

A=bh- rectangle with 5ft base and 4ft height

5·4=20

20·2=40

A=bh- rectangle with 7ft base and 5ft height

7·5=35

A= [tex]\frac{1}{2}[/tex]bh- triangle with 5ft base and 5ft height

[tex]\frac{1}{2}[/tex](5)(5)=125

125·4= 50

A=bh- rectangle with 12ft base and 5ft height

12·5=60

A= s²- square with 5ft base and 5ft height

5²=25

96+40+35+50+60+25=306

Answer:

.27w+3=18

.27w=15

w=15/.27

w=55.5r

Sadly, there is no such number of wings. You can’t order fractional wings, only whole numbers of them. So you can either order 55 wings, paying $14.85 plus the $3 sauce charge, a total of $17.85, less than the $18 charge at restaurant W… or you can order 56 wings, paying $15.12 plus the $3 sauce charge, a total of $18.12, more than the $18 charge at restaurant W.

Even if you skip the sauce, you still end up picking either 66 (coming up short) or 67 wings (paying more)

The total cost, c, of n chicken wings can be represented by a system of equations.:c = 10; c = 0.50n + 1.50. The graph has been attached below. The total cost of 17 chicken wings is the same at both restaurants.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

a.) The cost of n chicken wings and sauce at restaurant x is represented by the equation: c = 10

The cost of n chicken wings and sauce at restaurant x is represented by the equation: c = 0.50n + 1.50

The system of equations is:

c = 10

c = 0.50n + 1.50

b.) To graph the system of equations, we can plot the two equations on the same coordinate plane. The x-axis represents the number of chicken wings, and the y-axis represents the cost in dollars.

The graph has been attached below.

For the equation c = 10, this represents a horizontal line at y = 10.

For the equation c = 0.50n + 1.50, this is a line that has a slope of 0.50 and y-intercept of 1.50.

c.) The total cost of the same number of chicken wings will be the same at both restaurants when the lines representing the cost at each restaurant intersect. This occurs at the point where the lines have the same y-value, which is the cost.

To find the point of intersection, we can solve the system of equations by setting the two equations equal to each other and solving for n, the number of chicken wings.

c = 10

c = 0.50n + 1.50

Substituting the first equation into the second equation, we get:

10 = 0.50n + 1.50

Subtracting 1.50 from both sides, we get:

8.50 = 0.50n

Dividing both sides by 0.50, we get:

n = 17

This means that the total cost of 17 chicken wings is the same at both restaurants. At any number of chicken wings less than 17, the cost at restaurant x will be less than the cost at restaurant z. At any number of chicken wings greater than 17, the cost at restaurant z will be less than the cost at restaurant x.

Answer:

A. cost of 6 roses is 32 dollars

cost of 9 roses is 47 dollars

B. Cam can buy 6 roses

Step-by-step explanation:

for part A, plug the numbers in

2 + 5(6) = 32

2 + 5(9) = 49

for part B, we already know from Part A that six roses cost 32 dollars, and since he only has 32 dollars, he can afford 6 roses

Answer: $12.64 per ball.

Step-by-step explanation:

To find the cost of each soccer ball, you can divide the total cost ($75.84) by 6 to get:

75.84 ÷ 6 = 12.64

Therefore, it costs $12.64 for each soccer ball.

Answer:

triangle AEH is da good one

Step-by-step explanation:

Answer:

The correct option is triangle GDC

Step-by-step explanation:

The dimensions give for the cube are such that the top surface has vertices GBCF while the bottom surface has vertices HADE.

A right angle can be formed in quite a number of ways since the cube has right angles on all six surfaces. However the question states that the diagonal that forms the right angle runs "through the interior."

Therefore option 1 is not correct since the diagonal formed in triangle BDH passes through two surfaces. Triangle DCB is also formed with its diagonal passing only along one of the surfaces. Triangle GHE is also formed with its diagonal running through one of the surfaces.

However, triangle GDC is formed with its diagonal passing through the interior as shown by the "zigzag" line from point G to point D. And then you have another line running from vertex D to vertex C.
