What is 80% of 150? Please help

Answer: 16x+4

Step-by-step explanation:

perimeter = side + side + side

So in this case:

Perimeter= 3x+2+5x-5+8x+7= 3x+8x+5x+2+7-5 = 11x+5x+9-5 = 16x+4

Answer:

n-5=2n+9

Step-by-step explanation:

The value of x for which this model will make the least sense to use is at x=-2.75 seconds.

A function assigns the value of each element of one set to the other specific element of another set.

The function that is given to us is h(x) = –16x²+100 where x is the time in seconds.

Now, use the function to know the height of the object, therefore, the height of the object can be written as,

Time, t₁=0

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(0)=0+100\\\\h_1=100[/tex]

Thus, the height of the object when the time is 0 seconds is 100.

Time, t₂=0.5

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(0.5)=-4+100\\\\h_2=96[/tex]

Thus, the height of the object when the time is 0.5 seconds is 96.

Time, t₃=1

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(1)=-16+100\\\\h_1=84[/tex]

Thus, the height of the object when the time is 1 second is 84.

Time, t₄=1.5

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(1.5)=-36+100\\\\h_4=64[/tex]

Thus, the height of the object when the time is 1.5 seconds is 64.

Time, t₅=2

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(2)=0+100\\\\h_5=36[/tex]

Thus, the height of the object when the time is 2 seconds is 36.

Now as we can see that the error in the height of the object can be a maximum of 1, therefore, for different values of x, the change in height will be,

Time, t₆= -2.75

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(-2.75)=-121+100\\\\h_6= -21[/tex]

Thus, the height of the object when the time is -2.75 seconds is -21.

Hence, the value of x for which this model will make the least sense to use is at x=-2.75 seconds.

Step-by-step explanation:

We can write equations relating pears to oranges, solve them, and then find the number of apples. Let p, o, and 'a' represent the numbers of pears, apples, and oranges.

  p/o = 5/3 . . . . . the ratio of pears to oranges is 5:3

  p -o = 54 . . . . . there are 54 more pears than oranges

  a -o = 3 . . . . . .  there are 3 more apples than oranges

__

Multiply the first equation by 3/5o to get ...

  3/5p = o

Substitute that into the second equation:

  p -(3/5)p = 54

  2/5p = 54 . . . . . . simplify

  p = 54(5/2) = 135 . . . . multiply by 5/2 to get the number of pears

There are 135 pears in the basket.

__

  a = 3 +o = 3 +3/5p = 3 +3/5(135) = 3 +81 . . . . solve for the number of apples

  a = 84

The percentage of fruits that are apples is ...

  apples/total = 84/(135 +81 +84) = 84/300 = 28/100 = 28%

  28% of the fruits are apples

The rule that can be used to describe the x-coordinates in the translation is (x+6).

A translation is a sort of transformation that moves each point in a figure in the same direction by the same amount of distance.

We know that the coordinate is moving up, therefore, the coordinate of x will be increasing by 6 units.

Hence, the rule that can be used to describe the x-coordinates in the translation is (x+6).

A convex pentagon has interior angles that measure 60, 80, 120, and 140. What is the measure of the fifth interior angle?

Given -

To Find -

Solution -

Let us assume fifth interior angle as x

We know,

Sum of interior angles of a pentagon is 540°

60° + 80° + 120° + 140° + x° = 540°

→ 400° + x° = 540°

→ x° = 540° - 400°

→ x = 140°

Fifth interior angle of a pentagon = 140°

Yes, the square of a rational number is always positive.

We know that a negative times a negative equals a positive only.

Well, a negative squared also equals a positive.

For example, (-4)² is equal to 16.

Because

(-4)×(-4)=16

Step-by-step explanation:

The value of x is 17.6. She should have added 5.4 on both sides to get the correct value of x. Then the correct option is A.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Kaitlyn solved the equation for x using the following calculations.

[tex]\rm -5.4 + x =12.2[/tex]

and she did the calculation will be

[tex]\rm -5.4x = 6.8[/tex]

The mistake she did in this equation is the plus sign is removed between the -5.4 and x. And she subtracted 5.4 from 12.2.

The correct solution of the equation is to add both sides 5.4. Then we have

[tex]\begin{aligned} \rm -5.4 + x+5.4 &=12.2+5.4\\\\\rm x &= 17.6\end{aligned}[/tex]

If the Thompsons need the movers for more than 6 hours, City movers would be the better deal. Therefore, option D is the correct answer.

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.

Given that, the Thompson family was moving and hired Town Movers to move them for a fee of $30 plus $15 per hour.

Let the number of hours be x.

Now, 30+15x

Movers called and offered a fee of $72 plus $8 an hour, which they thought might be a better deal

72+8x

From the graph, both the movers have same charge at 6th hour and City movers charge is decreasing then compare to Town Movers.
