Step-by-step explanation:
The 3 angles in a triangle sum to 180°
Sum the 3 given angles and equate to 180
2x + 3 + 7x - 5 + 3x + 14 = 180 , collect like terms
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14
Then
∠ F = 7x - 5 = 7(14) - 5 = 98 - 5 = 93° → D

A bicycle has a speed of 6 m/s. What is its speed in km/h?
(1 km=1000 m)
(1 h = 3600 s)
answer:
m/s --- km/h = [tex]\frac{1000}{3600}[/tex]
km/h= [tex]\frac{5}{18}[/tex]
6m/s= [tex]\frac{6*5}{18}[/tex]
6m/s= 1.66 km/h
The speed of the bicycle in km/h is 21.6 km/h.
Given that;
A bicycle has a speed of 6 m/s.
Since we know that;
1 km = 1000 m
And, 1 hour = 3600 s
Hence change the speed of the bicycle in km/h as;
[tex]Speed = 6 m/s[/tex]
It can be equal to;
[tex]Speed = \dfrac{6 \times \dfrac{1}{1000} km }{\dfrac{1}{3600} seconds }[/tex]
[tex]Speed = 21.6 km/s[/tex]
Therefore, the speed of the bicycle in km/h is 21.6 km/h.

A class is having a water balloon tossing contest. There is a large tub of water. Gavin uses 3 1/5 quarts of water to fill some balloons, and Quinley uses 6 1/2 quarts to fill more balloons. Find the total change of volume of water in the tub
We want to find the total change in the volume of water of a tub, given that we know how much water is used.
The change in volume is: -(9 + 7/10) quarts.
To find the change in volume, we need to find the total volume of water used.
We do know that:
Gavin uses (3 + 1/5) quarts of waterQuinley uses (6 + 1/2) quarts of water.The total amount used is the sum of the two quantities above, we get:
(3 + 1/5) quarts + (6 + 1/2) quarts
(3 + 6 + 1/2 + 1/5) quarts
(9 + 7/10) quarts.
So the change in volume is related to this, and we should write:
Final Volume - Initial Volume = -(9 + 7/10) quarts.
Where the negative sign is because at the end we have less volume than at the beginning.

Step-by-step explanation:
Find the equation of the line.
A line that is parallel to the graph of 2x+3y=5 and contains the point (3,1)
Answer:
2x + 3y = 6
Step-by-step explanation:
The equation of a line in slope- intercept fprm is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y = 5 ( subtract 2x from both sides )
3y = - 2x + 5 ( divide terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{5}{3}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
Parallel lines have equal slopes, then
y = - [tex]\frac{2}{3}[/tex] x + c ← is the partial equation
To find c substitute (3, 1 ) into the partial equation
1 = - 2 + c ⇒ c = 1 + 2 = 3
y = - [tex]\frac{2}{3}[/tex] x + 3 ( multiply through by 3 to clear the fraction )
3y = - 2x + 6 ( add 2x to both sides )
2x + 3y = 6 ← equation of parallel line

Estimate the following square and cube roots by using the above process. Circle
any Rational Roots.
Please help❗️❗️❗️❗️❗️
The estimates of the square roots and cube roots using the attached process are;
1) √15 = 3.81
2) √44 = 6.6.
3) √81 = 9
4) ∛12 = 2.88.
5) ∛125 = 5
6) ∛320 = 6..8
The process we are to follow is shown in the attachment. The first thing we are to do is to list all the perfect squares from 1 to 100 and then do the same for all perfect cubes from 1 to 1000.Perfect squares from 1 to 100; 4, 9, 16, 25, 36, 49, 64, 81, 100
Perfect cubes from 1 to 1000; 1, 8, 27, 64, 125, 216, 343, 512, 729 and 1000.
1) √15;
The nearest perfect squares to it are; 9 and 16
Thus; √9 < √15 < √16
⇒ 3 < √15 < 4
This means that √15 is between 3 and 4.
Since 15 is closer to 16 than 9, it means √15 is closer to 4 and thus, we can estimate √15 as 3.81.
2) √44;
The nearest perfect squares to it are; 36 and 49
Thus; √36 < √44 < √49
⇒ 6 < √44 < 7
This means that √44 is between 6 and 7.
Since 44 is closer to 16 than 9, it means √44 is closer to 6 and thus, we can estimate √44 as 6.6.
3) √81
This is a perfect square and the method used to estimate other non-perfect square doesn't apply here. Thus; √81 = 9
4) ∛12
The nearest perfect cubes to it are; 8 and 27
Thus; ∛8 < ∛12 < ∛27
⇒ 2 < ∛12 < 3
This means that √12 is between 2 and 3.
Since 12 is closer to 8 than 27, it means ∛12 is closer to 2 than 3 and thus, we can estimate ∛12 as 2.88.
5) ∛125
This is a perfect cube and the method used to estimate other non-perfect cubes doesn't apply here. Thus; ∛125 = 5
6) ∛320
The nearest perfect cubes to it are; 216 and 343
Thus; ∛216 < ∛320 < ∛343
⇒ 6 < ∛320 < 7
This means that ∛320 is between 6 and 7.
Since 320 is closer to 343 than 216, it means ∛320 is closer to 7 than 6 and thus, we can estimate ∛320 as 6..8
