Devaughn is 13 years younger than Sydney. The sum of their ages is 79 . What is Sydney's age?

Answers

Answer:

26

Step-by-step explanation:

Let D =Devaughn's age

S= Sydney's age

So D+S=64

D=S+12

Now

D+S=64⇒D=64−S

and so

S+12=64−S 2S=52

S=26

Therefore

D=S+12

D=38

(ii) Find the ratio of the number of females and the total number of members.
​

please fast

Answers

i) the ratio of males to females is 8:4
ii) the ratio of females to total number of family members is 4:12

i) because the total number is 12
12-8=4
therefore there are 4 females in the family
So the answer is 8:4

ii) because we know there are 4 females and there’s 12 members in the family so the answer is 4:12

Answer:

∠KNC = 99°

Step-by-step explanation:

∠JNM + ∠KNC = 180    (it is a straight line)

∠KNC = 180 - ∠JNM

∠KNC = 180 - 81

∠KNC = 99°

Answer: 99°

Step-by-step explanation: They are supplementary so 180 - 81 = 99

1. Priya jogs at a constant speed. The relationship between her distance and time is
shown on the graph. Diego bikes at a constant speed twice as fast as Priya.
Sketch a graph showing the relationship between Diego's distance and time.

Answers

Answer:

Step-by-step explanation:

Relationship between distance the distance and time for Priya has been given  in the graph.

Therefore, slope of the line on the graph will represent the speed of jog of Priya.

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points lying on the line.

Since, (0, 0) and (0.4, 2) are lying on the line.

Therefore, slope or speed of the line will be,

Speed = [tex]\frac{2-0}{0.4-0}[/tex]

           = 5

Now Diego bikes at a speed twice as fast as Priya,

So Diego's speed = 5×2 = 10 mile per hour

Therefore, slope of the line for Diego on graph will be,

m = 10

Line passing through origin and slope = 10 will be,

y = 10x

Points representing Diego's speed will be,

x      0      0.1       0.2     0.3     0.4     0.5

y      0        1          2        3        4         5

Now we can graph these points to get the line.

Relationship between distance the distance and time for Priya has been given  in the graph.

Therefore, slope of the line on the graph will represent the speed of jog of Priya.

Slope =

Where  and  are the points lying on the line.

Since, (0, 0) and (0.4, 2) are lying on the line.

Therefore, slope or speed of the line will be,

Speed =

          = 5

Now Diego bikes at a speed twice as fast as Priya,

So Diego's speed = 5×2 = 10 mile per hour

Therefore, slope of the line for Diego on graph will be,

m = 10

Line passing through origin and slope = 10 will be,

y = 10x

Points representing Diego's speed will be,

x      0      0.1       0.2     0.3     0.4     0.5

y      0        1          2        3        4         5

Now we can graph these points to get the line.

P(2) = 2² - 5(2) + a = 0 , so

4 - 10 + a = 0

A motorboat maintained a constant speed of 16 miles per hour relative to the water in going 55 miles upstream and then retuming. The total time for the tip was 8.0 hours. Use this information to find the speed of the current.​

Answers

Answer:

6 mph

Step-by-step explanation:

Let the speed of the current be c

Time upstream is

55/(16 + c)

Time downstream is

55/(16 - c)

Total time is 8 hours

55/(16 + c) + 55/(16 - c) = 855(16 -c + 16 + c)/(16 + c)(16 - c) = 855*32= 8*(16² - c²)220 = 256 - c²c² = 36c = 6 mph

A rope is 225 centimeters long.
You need the rope to be 1 1/2 meters long.

For every 1 litre of water used to make a medicine, 150 ml of sucrose and 600ml of saline solution are used. Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

Answers

Quantity of water used to make a medicine :-

[tex]= \texttt{1 \: litre }[/tex]

[tex] =\texttt{ 1×1000 \: ml}[/tex]

[tex] =\texttt{\color{hotpink} 1000 \: ml}[/tex]

This quantity of water required to make a medicine = 1000 ml

Quantity of sucrose used to make a medicine = 150 ml

Quanity of saline solution used to make a medicine = 600 ml

The quantity of water to sucrose to saline solution needed to make a medicine as a ratio :-

[tex] = \texttt{1000 : 150 : 600}[/tex]

Cutting each common zero in this ratio, we get :-

[tex] = \texttt{100 : 15 : 60}[/tex]

Dividing each number in the ratio by 5, we get the ratio :-

[tex] =\texttt{ \color{hotpink}20 : 3 : 12}[/tex]

Since, the three numbers in this ratio doesn't have any common factors we can conclude that we have found out the simplest form of the ingredients needed to make the medicine .

Therefore, the ratio of water to sucrose to saline solution needed to make a medicine = 20:3:12

What is f(4) for the function f(x) = 6x +3?
f(4)=0

Answers

F(4)=6(4) +3
= 24+3=27
F(4)=27.

The value of function  f(4) is 27.

It is required to find the value of function  f(4).

What is function?

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given that:

The function is

f(x) = 6x +3

Now put the value x=4 in the given function, we get

f(4)=6(4) +3

= 24+3

=27

f(4)=27.

Hence, the value of function  f(4) is 27.
