A boy is twice as tall as his little sister and 30cm shorter than his father. Their combined height is 3.8 meters. Find (in cm) the height of each person.
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
Two numbers are in the ratio 5:2 and their sum is 56. Find the numbers. Please plain how to do this
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
The ratio of males to females in a tennis club is 4:3 what fraction are female?
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.

b. Grandpa Dewitt planted an oak tree 58 years ago and it is now 14 metres high. When
he planted the oak, it measured 1 metre in height. How much did the oak tree grow
on average each year?
how would i write the equation?
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

(-6, -2) and (5, 1) find the distance between these two points using the distance formula
(just trying to check my work because i did this question twice and one answer was 6 the other was 11.4)
Answer:
The answer is 11.401754
Answer: Approximately 11.4 units
================================================
Work Shown:
(x1,y1) is the first point (-6,-2)
(x2,y2) is the second point (5,1)
Apply the distance formula
[tex]d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(-6-5)^2+(-2-1)^2}\\\\d = \sqrt{(-11)^2+(-3)^2}\\\\d = \sqrt{121+9}\\\\d = \sqrt{130}\\\\d \approx 11.4017542509913\\\\d \approx 11.4\\\\[/tex]
The distance between the two points is roughly 11.4 units.
Determine if the triangles are similar. If similar, state how and complete the similarity statement.
The triangles are___
TUS~ ___
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.
What are Similar Triangles?Similar triangles have corresponding angles that are congruent to each other and also have corresponding congruent sides that are proportional to each other.Similar triangles always possess the same shape but different sizes.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.

Evaluate each function at the given value. 1) f (x) = x3 − x2 − 25x + 35 at x = −5 2) f (n) = −4n4 − 13n3 − 5n2 + 16n + 18 at n = −2
Answer:
a) f(-5) =10
b) f(-2) = 26
Step-by-step explanation:
Given that the function
f (x) = x³ − x² − 25x + 35
Put x =-5
f(-5) = (-5)³ - (-5)²-25(-5)+35
= -125-25+125+35
= 10
f(-5) =10
ii)
f(n) = -4n⁴ - 13n³-5n²+16n+18
f(-2) = -4(-2)⁴ -13(-2)³-5(-2)²+16(-2)+18
= -4(16)-13(-8)-5(4)-12+18
= -64 +104-20-12+18
= 122-96
= 26
f(-2) = 26
