The directions for dragging the balls into the images have been provided as follows:

1. For every 4 basketballs, there are 5 baseballs: Drag four basketballs and five baseballs into the box.

2. The ratio of basketballs to baseballs is 5:4: Drag ten basketballs and 8 baseballs into the box.

3. 4/5 of the balls are basketballs: Drag 8 basketballs and 2 baseballs into the box.

In order to drag the balls into the boxes, you need to first understand the mathematical expression for each of the boxes and input the right number of balls as stipulated.

For instance, in the first box where we are told that for every 4 basketballs, there are five baseballs, we can simply drag 4 basketballs and 5 baseballs into the box. For the last statement where we are told that 4/5 of the balls are basketballs, we could assume a total of ten balls where 8 are basketballs and 2 are baseballs.

Step-by-step explanation:

x= 9

x×2=2x

9×2=18

18-2= 16

Answer:

2 - (3x – 4) = 2x – 9​

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2−(3x−4)=2x−9

2+−1(3x−4)=2x−9(Distribute the Negative Sign)

2+−1(3x)+(−1)(−4)=2x−9

2+−3x+4=2x−9

2+−3x+4=2x+−9

(−3x)+(2+4)=2x−9(Combine Like Terms)

−3x+6=2x−9

−3x+6=2x−9

Step 2: Subtract 2x from both sides.

−3x+6−2x=2x−9−2x

−5x+6=−9

Step 3: Subtract 6 from both sides.

−5x+6−6=−9−6

−5x=−15

Step 4: Divide both sides by -5.

−5x

= −15

Answer:

Printer B

Step-by-step explanation:

If printer A prints 36 pages every 1.5 minutes (90 seconds) we can divide 90 seconds by 36 to determine how long it takes Printer A to print one page. When we do that, we get 2.5 seconds which means it takes Printer A 2.5 seconds to print one page.

If we do the same with Printer B, we can divide 3 minutes (180 seconds) by 114 to get about 1.5 seconds which means it takes Printer B about 1.5 seconds to print one page.

If we do the same with Printer C, we can divide 5 minutes (300 seconds) by 115 to get about 2.6 seconds which means it takes Printer C about 2.6 seconds to print one page.

From this we can determine which printer prints the fastest and our answer will be Printer B.

Answer:

the answer is B

Step-by-step explanation:

So i divided every printer and Printer B was the highest

The sentence is true because the expressions are equivalent.

An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=7x+3. Where:

m= the slope.

b= the constant term that represents the y-intercept

For the given example: m=7 and b=3.

The linear equations are considered equivalent when they are equal.

The given equations are 5y+4−3y = 2y+4. Solving theses equations, you have:

5y+4−3y = 2y+4

2y+4 = 2y+4

Like the both equation present the slope and the constant term equal, the expressions are equivalent.

The product of 4.0x10^-2m and 8.1 is 3.24x10^-1m.

To express the product of 4.0x10^-2 m and 8.1, we can perform the multiplication and simplify the result. Let's go through the steps:

Step 1: Multiply the numbers: 4.0x10^-2 m * 8.1

To multiply these numbers, we multiply the decimal parts and add the exponents of 10. The calculation is as follows:

4.0 * 8.1 = 32.4

Next, we add the exponents:

10^-2 * 10^0 = 10^-2+0 = 10^-2

Step 2: Simplify the result

The result of the multiplication is 32.4 times 10 raised to the power of -2. We can write this as:

32.4 * 10^-2

When we have a number expressed in scientific notation, such as 4.0x10^-2 m, it means that we have a coefficient (4.0) multiplied by 10 raised to a certain power (-2 in this case). This notation is commonly used to represent very large or very small numbers in a concise and convenient manner.

In the context of measurements, the coefficient (4.0) represents the numerical value, and the exponent (-2) indicates the order of magnitude or scale. The base of 10 implies that the number is expressed in powers of 10.

Multiplying this value by 8.1 results in a product of 32.4. The exponent remains the same since multiplying by 10 does not change the scale of the number. Therefore, the final result is 32.4 times 10 raised to the power of -2.

Interpreting this in practical terms, the product of 4.0x10^-2 m and 8.1 is equivalent to 32.4 times 10 raised to the power of -2 meters. This can be understood as a small distance or length measurement due to the negative exponent. It signifies that the number is scaled down by a factor of 100 (10 raised to the power of 2), making it 100 times smaller than a meter.

Thus, the expression 32.4 * 10^-2 m represents the product of 4.0x10^-2 m and 8.1, where the value is 32.4 and the unit is meters, adjusted according to the appropriate scale denoted by the exponent.

The value of the given algebraic expression is -63/8.

To evaluate an algebraic expression, we substitute the values of the variables in the expression, and then follow the rules of solving a numeral expression.

In the question, we are asked to evaluate the algebraic expression:

{(3a - b)/2c} + {(3a - c)/(c - b)}, given the values of a = 3, b = -2, and c = -4.

To evaluate the expression {(3a - b)/2c} + {(3a - c)/(c - b)}, given the values a = 3, b = -2, and c = -4, we substitute these values in the expression and solve as follows:

{(3(3) - (-2))/2(-4)} + {(3(3) - (-4))/((-4) - (-2))}

= {(9 + 2)/(-8)} + {(9 + 4)/(-4 + 2)}

= {-(11/8)} + {-(13)(2)}

= -(11/8) - (13/2)

= -(11/8) - (52/8)

= -(63/8).

Thus, the value of the given algebraic expression is -63/8.

The required equation for the distance D the end of the spring is below equilibrium in terms of seconds t is D(t) = 16e^(-0.2167t) sin(40πt).

The amplitude of the spring is decreasing exponentially, which means it will be in the form of a decaying exponential function:

A(t) = A0e^(-kt)

Where A0 is the initial amplitude, k is a positive constant, and t is time.

According to the problem, the initial amplitude is 16 cm, and the amplitude decreases to 11 cm after 3 seconds.

So, we can write the equation as follows:

11 = 16e^(-k*3)

Solve for k:

11/16 = e^(-3k)

ln(11/16) = -3k

k = ln(16/11) / 3

Substitute the value of k in the exponential function:

A(t) = 16e^(-0.2167t)

The spring oscillates 20 times each second, so its frequency is 20 Hz or 20 cycles per second.

The period of the oscillation can be found by T = 1/f, where f is the frequency.

T = 1/20 = 0.05 seconds

The general equation for the distance D of the end of the spring below equilibrium can be written as follows:

D(t) = A(t) sin(2πft)

D(t) = 16e^(-0.2167t) sin(2π(20)t)

D(t) = 16e^(-0.2167t) sin(40πt)

Therefore, the required equation for the distance D the end of the spring is below equilibrium in terms of seconds, t is  D(t) = 16e^(-0.2167t) sin(40πt).

In a multiple regression problem involving two independent variables X1 and X2, if b1 is computed to be +2.0, it means that. the relationship between X1 and Y is significant .

Multiple regression is a statistical method that may be used to assess a single dependent variable and several independent variables. Multiple regression analysis use known independent variables to anticipate the value of a single dependent variable. Each predictor value is assigned a weight, which indicates how much each predictor contributed to the overall forecast.

In a multiple regression problem involving two independent variables X1 and X2, if b1 is computed to be +2.0, it means that. the relationship between X1 and Y is significant .

The estimated value of Y increases by an average 2 units for each increase of 1 unit of X1, holding X2 constant.

Step-by-step explanation:

If there were 100 students in the school, then  38 have a dog 24 a cat and 11 have both.

So there are 38 - 11 = 27 who only have a dog and 24-11 = 13 who only have a cat.

So total number having a pet = 27+11+13

= 51 students.

So Prob(You will choose a student with a pet) = 51%.
