Answer:

B) 16√t

Average speed of the car =16√t inches per second

Step-by-step explanation:

A) 4√t

B) 16√t

C) 16 / √t

D) 16t

Speed = distance / time

Distance = 16t√t

Time = t

Substitute the value of distance and time into the formula

Speed = distance / time

Speed = 16t√t / t

= 16√t

Therefore, speed = 16√t

Average speed of the car =16√t inches per second

Answer:

side length and perimeter of 1 face

area of 1 face and surface area

Step-by-step explanation:

The missing options are:

In the picture attached, the cube measurements are shown:

In a linear relationship:

variable a / variable b = k

Case: side length and perimeter of 1 face

12/3 = 16/4 = 20/5 = 24/6 = 4

Case: perimeter of 1 face and area of 1 face

12/9 ≠ 16/16 ≠ 20/25 ≠ 24/36

Case: surface area and volume

54/27 ≠ 96/64 ≠ 150/125 ≠ 216/216

Case: area of 1 face and surface area

54/9 = 96/16 = 150/25 = 216/36 = 6

Case: side length and volume

27/3 ≠ 64/4 ≠ 125/5 ≠ 216/6

The side length and the perimeter of one face have a linear relationship.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept.

From the graph:

The side length and the perimeter of one face have a linear relationship.

y=-3x+1  which is equivalent to y+3x=1

y=-x+5  which is equivalent to y+x=5

subtract the two equations :

y+3x-(y-x)=1-5

2x=-4

Answer:

x° = 62

Step-by-step explanation:

The vertical angle to 28 degrees is 28 degrees in size.

The vertical angle to 90 degrees is 90 degrees in size.

Angles in a circle add up to 360 degrees.

x + 28 + 152 + 28 + 90 = 360

x + 298 = 360

x = 360 - 298

x = 62

Angle x is 62 degrees in size.

The properties of exponents, which mathematical operation changes 2 1/3 to 2 is 2^(1/3) * 2^(2/3) = 2

The steps are as follow:

a^m * a^n = a^(m + n)

2^1 = 2^(1/3) * 2^n

2^1 = 2^(1/3)+n

1 = (1/3) + n

n = 2/3

So the properties of exponents, which mathematical operation changes 2 1/3 to 2 is 2^(1/3) * 2^(2/3) = 2

Answers:

minor arc RP = 125 degrees

minor arc QS = 125 degrees

============================================================

Explanation

Definition: A minor arc is a piece of a circle such that it is smaller than a semi-circle with the same radius. In other words, it's measure is always less than 180 degrees.

Based on this definition, a minor arc is where we take the shortest path between any two points on a circle. For minor arc RP, we start at R then go to the right and take the shortest path to P. We do not go left when we start at R because that's the longer path and it is the major arc.

Minor arc RP is subtended by central angle ROP = 120 degrees. This central angle is equal to the arc measure in question. This isn't really a theorem, but more a definition if anything.

Central angle QOS is equal to angle ROP through the vertical angles theorem. Any pair of vertical angles are always congruent. Since QOS is 125 degrees, so is minor arc QS.

Answer:

Arc RP is 125, Arc QS is 125, Arc QR is 55, and arc SP is 55

Step-by-step explanation:

We know Arc QS is 125 degrees because angle QOS is a vertical angle with Angle ROS, so Arc QS is 125, and ARC RP is 125. We can figure out the other two arcs using the knowledge that ARC QR is equal to arc PS because angle QOR an SOP are vertical angles and all the degrees have to add up to 360. From this we get 2x + 125 + 125 = 360. From here we simplify and get 2x + 250 = 360; 2x = 110; x = 55, so arc QR and ARC SP are both 55.

[tex]P(Male) = \frac{1}{3}[/tex]

Step-by-step explanation:

Given

[tex]Male = 4[/tex]

[tex]Female = 8[/tex]

Required

Probability of selecting a male

First, we need to get the total population;

[tex]Total = Male + Female[/tex]

[tex]Total = 4 + 8[/tex]

[tex]Total = 12[/tex]

Let P(Male) represent Probability of Male

Let n(Male) represent number of Male

[tex]P(Male) = \frac{n(Male)}{Total}[/tex]

[tex]P(Male) = \frac{4}{12}[/tex]

Simplify fraction by dividing the numerator and denominator by 4

[tex]P(Male) = \frac{1}{3}[/tex]

Hence, the probability of selecting a male is 1/3

Good luck on your assignment..

Solution:

x + y = 11, -x = -y - 9

~Isolate x in [ x + y = 11 ]

x = 11 - y

~Substitute x in the other equation

-(11 - y) = -y - 9

~Simplify

-11 + y = -y - 9

y = -y + 2

2y = 2

y = 1

~Substitute y in the first equation

x + 1 = 11

~Simplify

x = 10

Therefore, the solution to the system of equations is (10, 1)

The third option, or initial value:2, rate of change:1.

Step-by-step explanation:

The initial value is where the y-intercept is on the y-axis. For this problem it falls on the 2.

if there are 54 in total, and 32 are women, that means 22 are men, we get this by subtracting 32 from 54 (54-32).

then if 18 of the 41 are male, who are right handed, subtract 18 from 41  (41-18) to get 23. that means there are 23 right handed women.

then we do 32-23 to get 9, this is how many left handed women there are.

then we do 22-18 which is 4. there are 4 left handed males

Answer:

B)140

Step-by-step explanation:

So a line is=180 and the interior angles of a triangle= 180, so I did some manipulations

1. 100 + (5x+5) + <ECD = 180. But we also know that (21x-7) + <ECD=180. With some manipulation we can find that <ECD= 180 - (21x-7), so we can plug that into the other equation

2. Now: 100 + (5x+5) + (180- (21x-7))= 180

3. Solve:

105+5x+180-21x+7=180

112-16x=0

112=16x

x=7

4. Plug x=7 into 21x-7= 140

The correct options are:

(8,4)

(16,8)

Step-by-step explanation:

The table is given which shows the number of yellow tiles and red tiles.

The first row in the table shows that if there are 4 red tiles then there will be 2 yellow tiles. This relation can be defined as the number of red tile will always be double the amount of number of yellows tiles. Carter graphs this point as (4,2) where number of red tiles are plotted on x axis and number of yellow tile are plotted on y axis.

Consider the second row of the table. Number of red tiles is 8 while number of yellow tiles is 4, so the point he plots on the graph is (8,4)

Similarly, other points are (12,6) and (16,8)

Answer:

a) 78°

b) 39°

Step-by-step explanation:

In circle with center O, DE is tangent at point A and AC is chord (or secant if extended both sides).

Therefore by tangent secant theorem.

[tex] m\angle CAE = \frac{1}{2} \times m\widehat{(AC)} \\\\

\therefore 39\degree = \frac{1}{2} \times m\widehat{(AC)} \\\\

\therefore m\widehat{(AC)} = 39\degree\times 2\\

\red{\bold{\therefore m\widehat{(AC)} = 78\degree}}\\[/tex]

Since, measure of central angle of a circle is equal to the measure of its corresponding minor arc.

[tex] \therefore m\angle AOC = m\widehat{(AC)}\\

\huge \purple {\boxed {\therefore m\angle AOC = 78\degree}} \\[/tex]

Next, by inscribed angle theorem:

[tex] m\angle CBA = \frac{1}{2}\times m\widehat{(AC)}\\\\

\therefore m\angle CBA = \frac{1}{2}\times 78\degree \\\\

\therefore m\angle CBA =39\degree \\\\

Square

There is a half chance of picking a letter that is a vowel in the word "square". (Three is half of six.)
