Answer:

Step-by-step explanation:

You can do this using a small equation.

120% x = 96                    Change 120% to a decimal

120/100 * x = 96             Multiply by 100

120x = 96 * 100

120x = 9600                   Divide by 120

x = 9600/120

x =  80

Look what you got. 20% more than 80 is 96. x is smaller than 96.

If you take 20/100 * 80 = 16

if you add 16 to 80, you  get 96

Answer:

x = 80

Step-by-step explanation:

120 % of x = 96

or, 120/ 100 × x = 96 change percentage to 100 and devide

or, 6 / 5 × x = 96

or, 6x / 5 =96. multiply 6 and x

or, 6x = 96 × 5. change devide sign to multiply

or, 6x = 480. multiply

or, x = 480 / 6. change multiply sign to devide

therefore, x = 80

hope this answer will help you.

Answer:

Box C

Step-by-step explanation:

First switch the box that's in kilograms into grams. One kilogram=1000 grams. So box C is 1250 grams.

Next divide the amount in each box by the cost of each box.

Box A 500/173=2.89

Box B 750/260=2.88

Box C 1250/435=2.87

So, since box C has the lowest amount when divided, that box has the best value.

Answer:

x = -12

Step-by-step explanation:

Step 1: Subtract 5x from both sides.

3x + 4 - 5x = 5x + 28 - 5x

-2x + 4 = 28

Step 2: Subtract 4 from both sides.

-2x + 4 - 4 = 28 - 4

-2x = 24

Divide both sides by -2.

-2x/-2 = 24/-2

x = -12

Answer:

x= -12

Consider an engineering material of initial length Lo, Area (A), Modulus of elasticity (E) and applied a force P due to which change in the length of the material is δ2 from it’s original length (Lo)

Initial length of the material is Lo. Hence, at time t = 0 when no force applied on the material the length of the material will not change (i.e., at time t=0, δ1 = 0)

Modulus of elasticity of the material:

[tex]E=\frac{P \cdot L_{o}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]

Area of the material:

[tex]E=\frac{P \cdot L_{o}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]

[tex]A=\frac{P \cdot L_{o}}{E\left[\delta_{2}-\delta_{1}\right]}[/tex]

Length of the material:

[tex]E=\frac{P \cdot L_{0}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]

[tex]L_{0}=\frac{E \cdot A\left[\delta_{2}-\delta_{1}\right]}{P}[/tex]

The number of marbles in the bag is illustrated using proportions.

There are 15 basketballs in the bin

The given parameters are:

[tex]\mathbf{B : S = 3 : 1}[/tex]

[tex]\mathbf{S : D = 1 : 4}[/tex]

[tex]\mathbf{n = 40}[/tex]

First, we combine the ratios

[tex]\mathbf{B:S:D = 3:1:4}[/tex]

The number of basketballs is calculated as follows:

[tex]\mathbf{Basketball= \frac{B}{B + S + D} \times n}}[/tex]

So, we have:

[tex]\mathbf{Basketball= \frac{3}{3 + 1 + 4} \times 40}[/tex]

[tex]\mathbf{Basketball= \frac{3}{8} \times 40}[/tex]

[tex]\mathbf{Basketball= 3 \times 5}[/tex]

[tex]\mathbf{Basketball= 15}[/tex]

Hence, there are 15 basketballs in the bin

Given:

The composite figure.

To find:

The volume of the given composite figure.

Solution:

Given composite figure contains a cuboid and a pyramid.

Length, breadth and height of the cuboid are 8, 6 and 4 respectively.

Volume of a cuboid is

[tex]V_1=length\times breadth\times height[/tex]

[tex]V_1=(8)(6)(4)[/tex]

Length and breadth of the pyramid is same as the cuboid, i.e., 8 and 6 respectively.

Height of pyramid = 10 - 4 = 6

Volume of a pyramid is

[tex]V_2=\dfrac{1}{3}\times length\times breadth\times height[/tex]

[tex]V_2=(\dfrac{1}{3})(8)(6)(6)[/tex]

The volume of composite figure is

[tex]V=V_1+V_2[/tex]

[tex]V=(8)(6)(4)+(\dfrac{1}{3})(8)(6)(6)[/tex]

It can be written as

[tex]V=(\dfrac{1}{3})(8)(6)(6)+(8)(6)(4)[/tex]

Therefore, the correct option is A.

The 60 ounces equals 3.75 pounds.

We are given in question the relation between pound and ounce. So, using that to find out the result of converting 60 ounces to pound. We will simply divide the given number of ounces by number of ounces in a pound.

Representing the given relation in equation form -

16 ounces = 1 pound

Thus, 1 ounce = [tex]\frac{1}{16}[/tex] pounds

Rewriting the equation for 60 ounces

So, number of pounds in 60 ounces will be = [tex]\frac{1*60}{16}[/tex]

Performing multiplication and division to find the number of pounds in 60 ounces to

Number of pounds in 60 ounces = 3.75

Thus,  the result of converting 60 ounces to pounds is 3.75 pounds.

I will say that to know if its rational, you have to see if the integer can be written in a fraction (like 0.333, 89/10, -4, 0)

Answer:

Whole numbers: 3, [tex]\sqrt{4}[/tex], [tex]\frac{49}{7}[/tex], zero

Integer but not whole: -100, -34, -4, -[tex]\frac{8}{4}[/tex]

Rational number: 9.23456, [tex]\frac{1}{2}[/tex], [tex]\frac{89}{10}[/tex], 0.333_

Irrational number: [tex]\pi[/tex], 0.456783_, [tex]\sqrt{8}[/tex]

Step-by-step explanation:

Whole number is any number that does not have a decimal and is not negative. [tex]\sqrt{4}[/tex] = 2. [tex]\frac{49}{7}[/tex] = 7. 0 is not negative and does not have a decimal so it is also a whole number.

Integers are any number that does not have a decimal and can be both positive or negative. -[tex]\frac{8}{4}[/tex] = -2.

A rational number can have a decimal but the decimal digits must terminate or the digit must repeat.  [tex]\frac{1}{2}[/tex] is 0.5.  [tex]\frac{89}{10}[/tex] is 8.9 and 0.333_ repeats the digit 3 so it is rational.

An irrational number can have a decimal and the decimal digits must list on forever or not repeat. [tex]\pi[/tex] is naturally an irrational number as it does not repeat and it spreads on forever. 0.456783_ does not repeat and goes on forever due to the dash at the back. [tex]\sqrt{8}[/tex] is also not rational.

Answer:

he faked too much

Step-by-step explanation:

The class Midpoint =( Lower class limit + Upper class limit )/2

The “midpoint” (or “class mark”) of each class can be calculated as: Midpoint = Lower class limit + Upper class limit /2 . The “relative frequency” of each class is the proportion of the data that falls in that class.

If we look at the question attached below then

Upper class limit = 69

Lower class limit =50

class midpoints= 50+69/2

class midpoint= 59.5

Hence, the Midpoint =( Lower class limit + Upper class limit )/2

When a line segment is bisected into 2 halves, the two halves are equal. In this case, when AB is bisected by CD, AE and BE would be equal and each point on CD should be equidistant from point A and point B. Therefore, AC = AB.

Using a linear function, it is found that:

a) 36 ounces of food were there after 12 days.

b) It took 24 days for the bag to contain 16 ounces of food.

c) The bag weighed 56 ounces before it was opened.

d) It took about 33 days for the bag to be empty.

A linear function is defined according to the following rule:

y = mx + b

In which:

From the graph of the function, we have that:

Hence the function for the amount of food after t days is given by:

A(t) = 56 - 1.6667t.

After 12 days, the amount is given by:

A(12) = 56 - 1.6667(12) = 36 ounces.
