133 is 7% of what number

Answers

Answer 1

Answer: $\begin{array}{ccc}7\%&-&133\n\n100\%&-&x\end{array}\n\n7x=133\cdot100\ \ \ /:7\n\nx=(133\cdot100)/(7)\n\nx=19\cdot100\n\nx=1\ 900\to answer$

Answer 2

Answer:

133 is 7% of 1900.

100/7=14.28571428571429

133 x 14.28571428571429= 1900

1900-93%=133

1900+7%=2033

2033-1900=133

That's the best I can explain it

1) b. -2/3
2) a. -1
3) -33/16 (no correct answer from the choices)

Explanation
The slope of a line is simply the gradient.
The gradient is the ratio of change in y to change in x.
Gradient = (y2-y1)/(x2-x1)

Question 1
Slope =((7-1))/((1-10) )=6/(-9)=-2/3

Question 2
Slope = (6.1-3.1)/(-5.5—2.5)=3/(-3)=-1

Question 3
Slope = (5/2—3)/(-5—7/3)=(11/2)/(-8/3)=-33/16

For question 3, there is no correct answer.

Answer:

The slope of the line that passes through the pair of points (1, 7) and (10, 1) is $(-2)/(3)$

The slope of the line that passes through the points (-5.5, 6.1) and (-2.5, 3.1) is -1

The slope of the line that passes through the pair of points (-7/3, -3) and (-5, 5/2) is $(-33)/(16)$

Step-by-step explanation:

Formula of slope of line (m) : $(y_2-y_1)/(x_2-x_1)$

Part 1 : Points are (1, 7) and (10, 1)

$(x_1,y_1) =(1,7)$

$(x_2,y_2) =(10,1)$

So, using formula

Slope (m) $=(1-7)/(10-1)$

$=(-6)/(9)$

$=(-2)/(3)$

Thus the slope of the line that passes through the pair of points (1, 7) and (10, 1) is $(-2)/(3)$

Part 2:Points (-5.5, 6.1) and (-2.5, 3.1)

$(x_1,y_1) =(-5.5,6.1)$

$(x_2,y_2) =(-2.5,3.1)$

So, using formula

Slope (m) $=(3.1-6.1)/(-2.5-(-5.5))$

$=(-3)/(3)$

$= -1$

Thus the slope of the line that passes through the points (-5.5, 6.1) and (-2.5, 3.1) is -1

Part 3 : Points (-7/3, -3) and (-5, 5/2)

$(x_1,y_1) =(-7/3,-3)$

$(x_2,y_2) =(-5,5/2)$

So, using formula

Slope (m) $=((5)/(2)-(-3))/(-5-((-7)/(3)))$

$=((5)/(2)+3)/(-5+(7)/(3))$

$=(-33)/(16)$

Thus the slope of the line that passes through the pair of points (-7/3, -3) and (-5, 5/2) is $(-33)/(16)$

Beverly needs to make a container in the shape of a rectangular prism that holds 1000 in3 of liquid. The height of the container must be 10 in. She wants to use the dimensions that will allow her to use the least amount of material possible. Beverly’s mother says the difference in the amount of material will be too minor to worry about. Beverly believes it is possible to save more than half the material needed if they pick the right dimensions. Who is correct? Support your answer with specific numbers, and explain your reasoning. The dimensions are measured in whole units.

Answers

Given:
volume = 1,000 in³
height = 10 in

1,000 in³ / 10 in = 100 in² Area.

100 in²

Length Width Surface Area of the Rectangular prism
100 in 1 in 2,220 in²
50 in 2 in     1,240 in²
25 in 4 in    780 in²
20 in 5 in    700 in²


Surface area = 2(wl + hl + lw)

The best dimension is 20 inches by 5 inches by 10 inches. It has lesser surface area than other dimensions. Thus, it can save more materials.

roman paid $150 to join a handball club. he pays additional $15 every time he uses one of the club's handball courts. write an equation that describes roman's total cost for playing handball as a function of the number of times he plays

Answers

The equation to determine the total cost for playing handball is

f ( x ) = 15x + 150

where x is the number of times Roman plays

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of times Roman plays be = x

Now , the initial amount Roman paid to join the club = $ 150

The additional amount Roman pays for each play = $ 15

So , the equation will be

The total additional amount Roman pays if he plays x number of times is =
number of times Roman plays x additional amount Roman pays for each play

Total additional amount Roman pays if he plays x number of times is = 15x

So , the total cost of playing handball be f ( x ) , where x is the number of times Roman plays

Now , the equation will be

The total cost of playing handball f ( x ) = initial amount Roman paid + Total additional amount Roman pays

The total cost of playing handball f ( x ) = 150 + 15x

Therefore , the equation is f ( x ) = 15x + 150

Hence , The equation to determine the total cost for playing handball is

f ( x ) = 15x + 150

where x is the number of times Roman plays
