Answer:

40 and 16

Step-by-step explanation:

Let's say these numbers are 5x and 2x.

Their sum is 56, so

5x + 2x = 56

7x         = 56

x = 8

Now substitute the unknown value with 8.

5 · 8 = 40,

2 · 8 = 16

Explanation

Let's say we had 4 men and 3 women in the tennis club. This would make the ratio of males to females be 4:3.

We have 4+3 = 7 people total. Of that total, 3 are women, so 3/7 is the fraction of women in the group.

Answer:

144.2 cm

Step-by-step explanation:

Length of the iron rod is 7.4cm

Radius is 3.1m

Therefore the surface area can be calculated as follows

= 2πrl

= 2×3.142×3.1×7.4

= 144.2 I'm

Hence the surface area is 144.2cm

Answer:

Height of boy = 140 cm

Height of sister = 70 cm

Height of father = 170 cm

Step-by-step explanation:

Given that:

Combined height = 3.8 meters = 3.8*100 = 380 cm

Let,

b be the height of boy

s be the height of sister

f be the height of father

According to given statement;

b + s + f = 380     Eqn 1

b = 2s                  Eqn 2

b = f - 30             Eqn 3

Putting b=2s in Eqn 3

2s = f - 30

[tex]s=\frac{f-30}{2}[/tex]    

Putting these values in Eqn 1

[tex]f-30+\frac{f-30}{2}+f=380\\\frac{2f-60+f-30+2f}{2} = 380 \\\\5f - 90 = 760 \\5f = 760+90 \\5f = 850[/tex]

Dividing both sides by 5

[tex]\frac{5f}{5}=\frac{850}{5}\\f=170[/tex]

Putting f=170 in Eqn 3

b = 170 - 30

b = 140

Putting f=170 in Eqn 2

140 = 2s

s = 70

Hence,

Height of boy = 140 cm

Height of sister = 70 cm

Height of father = 170 cm

1) 3.21 by itself if rational, I don't know if the dots mean anything, but if they do, then it is irrational.

2) Pi is an irrational number as it repeats forever.

4? I havent done Inequalitys in so long

Answer:

Step-by-step explanation:

so all the angles of a triangle add up to 180 degrees

180-42-62= 76

so we know angle TUS is 76 degrees

the other triangle has an angle of 78 degrees which isn't 42, 62, or 76.

The triangles are not similar because similar shapes have congruent angles

Both triangles only have one pair of congruent angles (m∠TSU ≅ m∠RSQ), therefore, the triangles are not similar.

From the image given:

m∠TSU = m∠RSQ = 62°

m∠TUS = 180 - 42 - 62 = 76°

m∠QRS = 180 - 78 - 62 = 40°  

Thus, both triangles only have one pair of congruent angles (m∠TSU ≅ m∠RSQ), therefore, the triangles are not similar.

Answer:

It grew 0.22 ft on the average yearly

Step-by-step explanation:

Here, we want to calculate the average growth rate

We find the difference between the heights

That will be;

(14-1) = 13

divide by the number of years

= 13/58 = 0.22 meter per year

Answer:

Let the number of hours he worked at his weekday job be x and the number of hours he worked at his weekend job be y, then

From (1): 25 + y = 40

y = 40 - 25 = 15.

Therefore, Beneio worked for 25 hours at his weekday job and 15 hours at his weekend job.
