Answer:

Therefore no of apples in that group is 18

Step-by-step explanation:

Given:

No. of apples = 36

No. of pears = 20

Also it is given that grocer arranges the  fruit into groups that have the same ratio of apples to pears as the whole collection of fruit.

first we find the ratio of apples and pears in whole collection which is given below

No. of apples/No. of pears  = 36/20 = 9/5

Now its a problem of ratio

It is given that no of pear in one group is 10

Let the  no of apples in that group be X

According to the question

No. of apples in whole collection/ No. of pear in whole collection = No. of apples in the group/ No. of pears in the group  -------------> A

9/5 =X/10

=> X = (9*10)/5 = 18

Therefore no of apples in that group is 18.

QUESTION 20
Elodia [21]

Answer:

B. -55

Step-by-step explanation:

La resta entre ambas funciones consiste en la sustracción de términos semejantes como demostraremos a continuación:

1) f(x) =-2\cdot x ^{2}-6 Dado

2) g(x) = x+4 Dado

3) (f-g)(x) = (-2\cdot x^{2}-6)-(x+4) Definición de resta de funciones.

4) (f-g)(x) = (-2\cdot x^{2}-6)+(-1) \cdot (x+4)        (-1)\cdot a = -a

5) (f-g)(x) = (-2\cdot x^{2}-6) + (-x-4) Propiedad distributiva/(-1)\cdot a = -a

6) (f-g)(x) = -2\cdot x^{2}-x+(-6-4) Propiedad conmutativa

7) (f-g) (x) = -2\cdot x^{2}-x-10 Sustracción de términos semejantes/Resultados.

A continuación, evaluamos la función resultante en x = -5:

(f-g)(-5) = -2\cdot (-5)^{2}-(-5)-10

(f-g)(-5) =-55

Por ende, la respuesta correcta es B.

Please can someone help!
Rom4ik [11]

Answer:

51 mph

Step-by-step explanation:

→ The first thing we need is a formula which links speed, distance and time so,

Speed = Distance ÷ Time

Speed = mph

Distance = metres/miles

Time = hours

→ Since we want to work out the average speed of the entire journey we need to first work out the total distance and total time. Using the first sentence of the paragraph, it says that <em>the car travels at an average speed of 45 mph for 40 minutes, </em>we can rearrange the formula to work out the distance so,

Speed = Distance ÷ Time

→ Rearrange to get distance as subject

Distance = Speed × Time

→ Substitute in the values

Distance = 45 × 40

→ Remember that the time is hours but we substituted in minutes so we divide the time value by 60

40 ÷ 60 = 0.666666667

→ Substitute in the time value multiplied by the speed

Distance = 45 × 0.666666667 = 30

⇒ 30 metres/miles is overall distance for the first part of the journey

→ Now we have to work out the distance for the second part of the journey. State the distance formula.

Distance = Speed × Time

→ Substitute in the values into the distance formula

Distance = 60 × 25

→ Remember that the time is hours but we substituted in minutes so we divide the time value by 60

25 ÷ 60 = 0.416666667

→ Substitute in the time value multiplied by the speed

Distance = 60 × 0.416666667 = 25

⇒ 25 metres/miles is overall distance for the second part of the journey

→ Now we have to add the distance of both the journeys together

25 + 30 = 55

→ Then we add the times of the journey together

40 minutes + 25 minutes = 65 minutes

→ Convert 65 minutes into hours

65 ÷ 60 = 1.08333 hours

→ Substitute both values into the speed = distance ÷ time formula

Speed = 55 ÷ 1.08333 = 50.76923077

→ The question says to round it to the nearest whole number so,

50.76923077 = 51 mph
