Does the pump speed have a significant effect on the time taken for the pressure to reach its maximum value?

Answer:

The answer would be 116

Step-by-step explanation:

The angles X and Z would be equal at 32 so multiply them by 2 and you would get 64 subtract 64 from 180 and you would get 116

Answer:

Y =116

Step-by-step explanation:

We know that angle Z = angle X since they are base angles  and  the sides are the same length

The sum of the angles of a triangle are 180

X+Y+Z = 180

32+ Y + 32 = 180

64+Y=180

Y = 180-64

Y =116

Answer:

In Example 2, the relationship between the dependent variable a, the amount still owed, and the independent variable w, the number of weeks Ethan pays $5, is given by the equation:

a = 100 - 5w

If we increase the value of w by 1, then the new value of w becomes w + 1. To find out what happens to the value of the dependent variable a, we substitute w + 1 for w in the equation:

a = 100 - 5(w + 1)

a = 100 - 5w - 5

Simplifying this expression, we get:

a = 95 - 5w

Comparing this expression to the original equation, we see that the value of the dependent variable a decreases by 5 when the value of the independent variable w is increased by 1. Therefore, if Ethan pays $5 for one more week, the amount still owed will decrease by $5.

Answer:

9 feets

Step-by-step explanation:

From the question, we have our scale factor as:

4:9 = 4/9

Smaller circle /Bigger circle = 4/9

A circle has a radius of 4 feet. What is the radius of a bigger circle?

Let the radius of the bigger circle = x

This is calculated as:

4/9 = 4/x

Cross Multiply

4x = 9 × 4

x = 36/4

x = 9 feet

Therefore, the radius of the bigger circle is 9 feet

The total surface area of the prism will be 290.125 Square units.

The surface area of a rectangular prism is the measure of how much-exposed area a prism has. Surface area is expressed in square units.

The surface area of a rectangular prism is given by:

SA = 2 (lh +wh + lw )

where

l = 3

w = 4.25

h = 18.25

SA = 2 (3x18.25 + 4.25x18.25 + 3x4.25)

SA = 2 (54.75 + 77.5625 + 12.75)

SA = 2 (146.0625)

SA = 290.125 square units

The slope of the ideal vector, determined by examining the coefficients of the variables in the regression equation is:

Cleaning Ability: 2.3

Cost: 1.0

Disinfecting Ability: 0.6.

In this case, the regression equation is:

Overall Preference = -2.1 + 2.3 * Cleaning Ability + 1.0 * Cost + 0.6 * Disinfecting Ability

The coefficients of the variables represent the weights or importance assigned to each variable in determining the overall preference. Therefore, the slope of the ideal vector would be the coefficients of the variables in the regression equation.

Based on the given regression equation, the slope of the ideal vector would be:

Cleaning Ability: 2.3

Cost: 1.0

Disinfecting Ability: 0.6

These values indicate the relative importance or impact of each variable on the overall preference for Slippery Soap.

Using linear functions, it is found that:

\(y_G(x) = x + 30\)

\(y_A(x) = 3x + 10\)

A linear function has the following format:

\(y = mx + b\)

In which:

At Greenpoint Florist, $1 is charged per rose, plus $30 for the vase, hence, the equation is:

\(y_G(x) = x + 30\)

At Ashley's Flowers, $3 is charged per rose, plus $10 for the vase, hence, the equation is:

\(y_A(x) = 3x + 10\)

At the end of this answer, the two solutions are graphed, and it is found that when 10 roses are sold, the total cost would be of $40 for at both shops.

The value of the car after 2 years is ₹ 3,02,400.

After one year, the car's value decreased by 20%.

To find the new value, we need to multiply the original cost by

\((100\% - 20\%) or 80\%.\)

So, the value of the car after one year is

\(4,20,000 \times 0.8 = 3,36,000.\)

For the second year, the car's value decreased by 10%.

Again, we need to multiply the previous year's value by

\((100\% - 10\%) or 90\%\).

Therefore, the value of the car after the second year is

\(3,36,000 \times 0.9 = 3,02,400\).

Thus, the value of the car after 2 years is ₹ 3,02,400.

The probability that the number will be greater than 4 is 1/3 and the probability that the 2 numbers will be greater than 2 is 4/9.

So, Probability formula: P(E) = Favouravle events/Total events

The probability that the number will be greater than 4:

P(E) = Favouravle events/Total events

P(E) = 2/6

P(E) = 1/3

The probability that the 2 numbers will be greater than 2:

P(E) = Favouravle events/Total events

P(E) = 4/6

P(E) = 2/3

2 numbers: 2/3 × 2/3 = 4/9

Therefore, the probability that the number will be greater than 4 is 1/3, and the probability that the 2 numbers will be greater than 2 is 4/9.

The statement that is not true about a parallelogram is C) Opposite angles are bisected by diagonals.

The statement that is not true about a parallelogram is:

C) Opposite angles are bisected by diagonals.

In a parallelogram, opposite sides are equal (statement A), opposite angles are equal (statement B), and the diagonals bisect each other (statement D). However, opposite angles are not necessarily bisected by diagonals in a parallelogram.

The diagonals of a parallelogram intersect each other, but they do not necessarily bisect the opposite angles.

Categorical charts are useful in displaying nominal data or numerical data that splits nicely into different categories so you can quickly see comparative results and trends.

The type of chart that is useful in displaying nominal data or numerical data that splits nicely into different categories is called a categorical chart. Categorical charts allow you to quickly see comparative results and trends by displaying data in separate categories or groups. This makes it easier to identify patterns and trends in the data and to draw conclusions about the relationships between different variables.

Examples of categorical charts include bar charts, column charts, and pie charts. Bar charts and column charts are commonly used to display numerical data, while pie charts are often used to display proportional data. Categorical charts can be used in a variety of contexts, such as business, education, and scientific research, to help communicate complex data in a clear and concise manner.

Overall, categorical charts are a powerful tool for organizing and displaying data in a way that makes it easy to identify patterns and trends.

Answer:

Gross pay per week = $234

Federal income tax = $421.2

Social security = $174.96

Medicare =$40.71

net pay per week = $181

Total gross pay = $2,808

Total net pay = $2172

Step-by-step explanation:

Hi, to answer this question, first, we have to calculate Angela gross income per week:

18 hours per week x $13 per hour = $234 per week (gross)

234 x 12 =2,808

Amount taken ; multiply weekly gross pay by each percentage discount in decimal form (divided by 100)

Federal income tax = 234 x (15/100) = $35.1  (in 12 weeks = 35.1 x 12 = $421.2)

Social security = 234 x (6.2/100)= $14.508 (in 12 weeks = 14.5 x 12 = $174.96)

Medicare = 234 x (1.45/100)=$3.393  (in 12 weeks = 3.39x 12 = $40.71)

Total amount taken (per week)= 35.1+14.508+3.393=$53.001

Net pay per week = 234-53 = $181

For the total gross pay we have to multiply the weekly gross pay by the number of weeks (12)

Total gross pay = 234 x 12 =$2,808

Total net pay = 181 x 12 = 181 per week x 12 = $2172

Step-by-step explanation:

The three  numbers are -5, -15, and -10 .

Equations of straight lines and equations of degree less than 1 are called "linear equations". The linear equation formula can be written as Y = mx + b. where m is the slope of the line, b is the y-intercept, and x and y are the variables. Slope indicates the direction and slope of the line. This is because (0,y) is the point where the line intersects the y-axis.

b=3a

c=b+5

b-2c=5

b-2(b+5)=5

b-2b-10=5

-b=15

b=-15

c=-15+5
