Answer:

X = 145

Step-by-step explanation:

91 divided by 7 = 13  

91 divided by 7 = 13

52 divided by 4 = 13

We do not know what the X value is so we must multiply by 13 and we get: 143

Answer: they need 13.86 minutes to chop 14 pounds of carrots.

Step-by-step explanation:

Rohan can chop 6 pounds of carrots in 11 minutes, then he can chop:

6lb/11min = 0.55 pounds per minute.

Lewis can chop 6 pounds in 13 minutes, then he can chop:

6lb/13min = 0.46 pounds per minute.

Working together, they can chop:

0.55 lb/min + 0.46lb/min = 1.01 lb/min

So working together, they can chop 1.01 pounds per minute.

Now we want to answer:

how many minutes will it take for Rohan and Lewis to chop 14 pounds of carrots?

If they need a time T, we will have the equation:

(1.01 lb/min)*T = 14 lb

T = 14lb/(1.01 lb/min) = 13.86 min

This means that they need 13.86 minutes to chop 14 pounds of carrots.

Answer:

[tex]x=0, g(x) =-4[/tex]

Step-by-step explanation:

Given that:

Graph of [tex]g(x)=3|x|-4[/tex] represents the path of a person from their house to school and then from school to their friend's house.

First of all let us learn about the graph of an absolute function.

An absolute function first decreases and then starts increasing from one point.

At that point, value of [tex]x=0[/tex].

As per the problem statement given, the location of the school can only be the point that we have discussed above.

Given that the equation is:

[tex]g(x)=3|x|-4[/tex]

Let us put the value of [tex]x=0[/tex]

[tex]g(x)=3|0|-4\\\Rightarrow g(x)=-4[/tex]

Therefore, the location of the school is:

(0, -4)  or [tex]x=0, g(x) =-4[/tex]

Answer:

24

Step-by-step explanation:

Given that:

Total number of members who race = 18

Ratio of racers to divers = 6 : 2

To find:

Total number of members of the team = ?

Solution:

Given the ratio = 6 : 2

As per the ratio given, we can let the number of racers = [tex]6x[/tex]

and

As per the ratio given, we can let the number of divers = [tex]2x[/tex]

As the swim team members can either race or dive, we can say that:

Total number of members on the team = Number of racers + Number of divers

Total number of members on the team = [tex]6x+2x=8x[/tex]

As per the question statement, we are given that:

[tex]6x=18\\\Rightarrow x =\dfrac{18}{6}\\\Rightarrow x =3[/tex]

Therefore, total number of team members = 8 [tex]\times[/tex] 3 = 24

Answer:

1c 2a 3b

Step-by-step explanation:

step 1 is c

step 2 is a

step 3 is b

Answer:

The ratios in option b and d form a proportion.

Step-by-step explanation:

Option a)

1:2 or 1/2 is already in the simple form

Let us reduce 4:2 or 4/2 to check whether it is equal to 1/2 or not

as 4/2 = 2/1 which is NOT equal to 1/2

Thus, 1:2 and 4:2 are NOT in proportions

Option b)

1:2 or 1/2 is already in the simple form

Let us reduce 2:4 or 2/4 to check whether it is equal to 1/2 or not

as 2/4 = 1/2 which is EQUAL to 1/2

Thus, 1:2 and 2:4 are in proportions

Option c)

2:1 or 2/1 is already in the simple form

Let us reduce 2:4 or 2/4 to check whether it is equal to 2/1 or not

as 2/4 = 1/2 which is NOT equal to 2/1

Thus, 2:1 and 2:4 are NOT in proportions

Option d)

2:1 or 2/1 is already in the simple form

Let us reduce 6:3 or 6/3 to check whether it is equal to 2/1 or not

as 6/3 = 2/1 which is equal to 2/1

Thus, 2:1 and 6:3 are in proportions

Therefore, the ratios in option b and d form a proportion.

D:

Answer:

150 percent increase

Step-by-step explanation:

Answer:

y = Asin(Bx-C) + D

D is midline.  A is amplitude.  Period is 2π/|B|  (More useful for graphing and shows the effect of B).  Strictly speaking, the frequency is the inverse of period:  f = |B|/(2π), but a lot of math texts say frequency when they mean angular frequency which is rad/s vs. cycles/sec.  The angular frequency ω = 2πf  (2π rads/cycle) or just |B|.  Finally the function is translated to the right  C/B (to the left if C/B is negative)

Step-by-step explanation:

The sine function has a midline of 3, an amplitude of 4, and a period of 2π will be y = 4 sin(2πx) + 3.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The sinusoidal function is given as,

y = A sin(2πx + ∅) + k

Where 'A' represents the amplitude, '∅' represents the phase difference, '2πx' represents the time period, and 'k' represents the midline.

The sine function has a midline of 3, an amplitude of 4, and a period of 2π will be given as,

y = 4 sin(2πx) + 3

The sine function has a midline of 3, an amplitude of 4, and a period of 2π will be y = 4 sin(2πx) + 3.

Answer: 3 × 10^4

Step-by-step explanation:

9x10^2 is how many times as much as 3x10^-2?

9 × 10^2 = 9 × 100 = 900

3 × 10^-2 = 3 × 0.01 = 0.03

We then divide, this will be:

= 900/0.03

= 30000

This can be represented as:

30000 = 3 × 10^4

It can be clearly seen that 9 x 10^2 is is 3 x 10^4​ times of the number 3 x 10^-2.

Multiplication is one of the basic mathematical operations. When a number is multiplied by another, the it is a given number of times that number.

As such, we can we that 9 x 10^2 is is 3 x 10^4​ times of the number 3 x 10^-2.
