Answer:
x>=-8 and a colored in point on negative eight with an arrow to the right
Step-by-step explanation:
-7x<=56 is the given
to solve, we would divide both sides by -7. However, when dividing an inequality, the direction of the inequality sign flips (if you've heard the alligator example, the mouth opens in the opposite direction it was before)
so we know have x>=-8
On the number line, the colored in dot represents that the value it is on is within the set, and since this can also be equal to -8 we have to use a colored in dot because its within the possible values. If it was not <= or >= then we would use an open circle to represent it cannot be that value but can be anything in the direction the arrow is pointing.
The arrow would point to the right because x can be larger or greater than -8 as well

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.

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

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

[tex]\frac{1}{2} ^{2}[/tex] is actually just (1/2)(1/2) and that equals 1/4
2 - (2/3) you can simplify to (6/3) - (2/3). that equals 4/3
now put it together!

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.

Answer:

Step-by-step explanation:
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
