Step-by-step explanation:

Answer:

1. Jefferson drew a line 9.5 inches long. Brittany drew a line 10 times as long. What is the difference in length between the two lines? 9.5 x 10 = 95

95-9.5 = 85.5

2. A store has a contest to guess the mass of 10,000 peanuts. If a peanut has a mass of about 0.45 gram. What would be a reasonable guess for the mass of 10,000 peanuts? Show or explain your work.

4,500 grams because 0.45*10,000 is 4,500.

4. Isaac bought three packages of nuts. He bought one package of peanuts that weighed 3.07 pounds. He also bought two packages of pecans that weighed 1.46 pounds and 1.5 pounds. Did the peanuts or the pecans weigh more? How much more? Show or explain your work.

The one package of peanuts weigh more than both of the packages of pecans. (Work: 3.07-2.96= 0.11 pounds.) The package of peanuts weigh 0.11 pounds more than the 2 packages of pecans.

Answer:

the two numbers are -0.6 and -5.6

Step-by-step explanation:

start with two equations then answer

x-y=5 and x*y=3.36

take the second equation and get only one variable at one end

which is x=3.36/y

then try to exchange x with 3.36/y in the other equation so it will be

(3.36/y)-y=5 so y=-5.6 then exchange y with -5.6 in any equation lets say  the first one it will be

x-(-5.6)=5 so x=-0.5

Answer:

15 is the missing length

The required length of the slanted area is 15 yards.

In a right-angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.

Pythagorean theorem is defined as  to find the unknown side of a right-angled triangle. eg, Two sides of a right-angled triangle are given as 6 cm and 9 cm, then the hypotenuse (the third side) can be calculated using the formula, h² = p2²+ b²; where 'h' is the hypotenuse and 'p' and 'b' are the perpendicular and base.

Here,
let the hypotenuse be h
now applying the Pythagorean theorem,

h² = 9² + 12²
h²= 81 + 144
h² = 225
h = √225
h = 15

Thus, the required length of the slanted area is 15 yards.

Step-by-step explanation:

1.

Martha is incorrect

One point is 15% is equal to 0.15

And 1.5 is greater than 1.15, as 1.5 is just 1.50

Correct order is 0.03, 15%, 25%, 1.15, 1.5

Otherwise, 0.03, 0.15, 0.25, 1.15, 1.5

Step-by-step explanation:

x=3 is a vertical line intersecting 3 on the x axis parallel to the y axis. it can be shown a a line, but it is not a function. A function must have 1 y value for every x value. Here there is infinite y values for one x value therefore it is not a function, but a line.

The statement which best describes the equation x=3 is statement which is in option d which tells that the equation describes a line but not a linear function.

A function is relationship between two or more variables expressed in equal to form. In a function each value of x must have a corresponding v value. The value that is entered into function is domain of the function and the value which we are getting is known as codomain of function.

The given equation is x=3.

1) This statement says that the equation cannot be graaphed but it is incorrect because the line of this equation will be  vertical line parallel to y axis.

2) This statement says that the equation represents a function but not a linear function but it is also not correct because in this equation there are infinite values of y for the value of x which is a contradiction of the definition of function.

3) This statement says that the equation represents a linear function but it is also not correct because the equation is not a function then how it is a linear function.

4) This statement says that the equation represents a line but not a linear function. It is true because the graph of this equation is a line and the equation is not a linear function because it  is not a function.

Hence the statement which best describes the equation x=3 is statement which is in option d which tells that the equation describes a line but not a linear function.
