Answer:

3.25 seconds

Step-by-step explanation:

The maximum height will occur when the velocity of the ball reaches zero in the air.

Velocity is given as the derivative of height, dh/dt.

The equation of height given is:

[tex]h = -2t^2+ 13t + 24[/tex]

Differentiating height, h, with respect to time, t, we have:

[tex]v = dh/dt = -4t + 13[/tex]

When v = 0:

[tex]0 = -4t + 13\\\\=> 4t = 13\\\\t = 13 / 4 = 3.25 secs[/tex]

Therefore, it will take 3.25 seconds for the ball to reach maximum height.

Answer:

27

Step-by-step explanation:

7(6) = 42. 42-15 is 27

The value of this function for f(6) is 27.

A function is defined as a relation between the set of inputs having exactly one output each.

Mr. Wilson wrote the function f(x) = 7x – 15 on the chalkboard.

WE need to find the value of this function for f(6).

So, plug 6 into x

7(6)-15

42 - 15

= 27

Hence, the value of this function for f(6) is 27.

Answer:

They made and sold 7 masks with elastics in the month of April.

They made and sold 20 masks that tie in the month of April.

Step-by-step explanation:

Let the number of masks with elastic made and sold be x

And the number of masks that tie made and sold be y

Since the price of making one mask with elastic is $1.70

The total amount spent on making x masks with elastic = 1.7x

The price of making one mask that ties is $1.30

The total amount spent on making the masks that tie = 1.3y

Total cost price = 1.7x + 1.3y = 37.90 (eqn 1)

They are selling the masks with elastics for $5.60 and the masks that tie for $5.40.

Total revenue made from selling x masks with elastic = 5.6x

Total revenue made from selling y masks that tie = 5.4y

Total revenue = 5.6x + 5.4y = 147.20 (eqn 2)

Writing the two equations together

1.7x + 1.3y = 37.9

5.6x + 5.4y = 147.2

Solving the simultaneous equation

x = 7 and y = 20

Hence, they made and sold 7 masks with elastics and 20 masks that tie in the month of April.

Step-by-step explanation:

First, read this explanation of how to understand probability numbers.

A probability number is a number from 0 to 1. It can be written as a decimal, a fraction, or a percent, but it must be from 0 to 1. The numbers 0, 25%, 1/3, 0.75 are all examples of probabilities since they are all from 0 to 1. 25% is the same as 0.25; 1/3 is the same as 0.333... All probabilities are expressed as 0, 1, or a number in between 0 and 1.

A probability of 0 means the event will not happen. It is an impossibility.

A probability of 1 or 100% is a sure thing it will happen. It is certain it will happen.

A probability of 50% or 0.5 or 1/2 means it is as likely to happen as it is not to happen.

A probability of between 0 and 0.5 is more likely not to happen than to happen.

A probability of between 0.5 and 1 is more likely to happen than to not happen.

Now let's look at each one of the probabilities in your problem.

1. 1/4

1/4 is the same as 0.25 which is between 0 and 0.5. It is more likely to not happen.

1. b. Unlikely

2. 0.0

0.0 will definitely not happen.

2. e. Impossible

3. 0.50

0.50 can just as easily happen or not happen.

3. d. Equally Likely

4. 100%

100% is the same as 1. A probability of 1 means an event that is certain to happen.

4. a. Certain

5. 75/100

75/100 is the same as 3/4 and 0.75; 0.75 is between 0.5 and 1, so it is more likely to happen than to not happen.

5. c. Likely

Step-by-step explanation:

First, find how many girls are in the class

There are 12 boys. The rest of the 30 students will be girls.

12+g=30

Subtract 12 from both sides to get the variable by itself

12-12+g=30-12

g=18

There are 18 girls.

Now, we have to find the percent.

To do this, divide the part: the girls, by the whole: the entire class

part/whole

girls/class

There are 18 girls, and 30 students in the whole class

18/30

0.6

Convert 0.6 to a percent by multiplying by 100, or moving the decimal place 2 spots to the right

0.6*100=60

0.6--> 6.0--> 60.

So, 60% of the class is made up of girls

C

The integer with the greatest value is the one that is farthest to the right hand side of the number line

Step-by-step explanation:

The number line is constructed in a way such that we have a center point of zero with positive values to the right of the number line and negative values to the left of the number line.

Moving deeper right, we have an increase in positivity, with the more positive values rightwards, indicating an increase in the numbers to the right

Moving to the left, we have an increase in negativity, but a decrease in value. The negative numbers closer to zero are more positive and command higher values than the values which are farther from zero.

What these indicates is that the more rightward a number, the greater its value

Answer:

110

Step-by-step explanation:

The probability of students entering the medical field = p = (11/50)

The number of people that'll enter the medical field out of 500 = np

n = 500

p = (11/50)

np = 500 × (11/50) = 110

Hope this helps!!!

Answer:

110 Students

Step-by-step explanation:

The probability of students entering the medical field is [tex]\dfrac{11}{50}[/tex].

In an experimental trial, this probability is referred to as the relative frequency of students entering the medical field.

Given that there are 500 students, we want to determine how many will enter the medical field.

We use the formula:

[tex]\text{Number of Expected Outcome}=$Relative Frequency of Outcome X Total Number of Trials$\\\\=\dfrac{11}{50}X500 \\\\=110[/tex]

Therefore, 110 students will be expected to enter the medical field.

Answer:

400 cubic cm

Step-by-step explanation:

Given that base is square and is side is 10 cm

area of square is given by side^2

Thus, area of base of cuboid  = [tex]10^2[/tex] square cm = 100 sq. cm

We know volume for any cuboid is area of base * height

height is 4cm

thus, volume of cuboid = area of base of cuboid * height

                                     = 100 * 4 cubic cm = 400 cubic cm

Volume of cuboid is 400 cubic cm.

Unit is cubic cm

The volume of square based cuboid is [tex]400cm^{3}[/tex].

Given that, base is square and side of base is 10 cm.

Height of the square-based cuboid.is 4cm.

Area of base = [tex](side)^{2}=(10)^{2}=100cm^{2}[/tex]

Volume of the cuboid is multiplication of base area and height of the cuboid.

  [tex]Volume=100*4=400cm^{3}[/tex]

Hence, the volume of square based cuboid is [tex]400cm^{3}[/tex].

Answer: The correct answer is D!!! 60

Step-by-step explanation:

The measure of the value of x from the given quadrilateral is 81 degrees.

From the given diagram, the quadrilateral is inscribed in the circle.

USing the theorem; "the sum of opposite angle of a quadrilateral is 180degrees, hence;

x + 98 = 180

Subtract 98 from both sides

x + 98 - 98 = 180 -98

x = 180 - 98

x = 81 degrees

Hence the measure of the value of x from the given quadrilateral is 81 degrees.

Answer:

Area of the quadilateral = 35 square units.

Step-by-step explanation:

The coordinates of the quadilateral DEFG are given as

D(6,1), E(2,4), F(-5,4) and G(-1,1).

To obtain the area, we need the length of each of the quadilateral's sides.

The length of each side is the distance between the coordinates given.

The distance between two coordinates (x₁, y₁) and (x₂, y₂) is given as

d = √[(y₁ - y₂)² + (x₁ - x₂)²]

The lengths of the quadilateral's sides include DE, EF, FG and GD

DE = distance between D(6,1) and E(2,4)

DE = √[(1 - 4)² + (6 - 2)²]

DE = √(9 + 16) = 5 units

EF = distance between E(2,4) and F(-5,4)

EF = √[(4 - 4)² + (2 - -5)²]

EF = √(0 + 49) = 7 units

FG = distance between F(-5,4) and G(-1,1).

FG = √[(1 - 4)² + (-1 - -5)²]

FG = √(9 + 16) = 5 units

GD = distance between G(-1,1) and D(6,1)

DE = √[(1 - 1)² + (-1 - 6)²]

DE = √(0 + 49) = 7 units

The dimensions of the quadilateral show that it is a rectangle.

The area of a rectangle = (length) × (width)

Length = 7 units

Width = 5 units

Area of the quadilateral = 7 × 5 = 35 square units.
