During summer vacation you charge people $8 per hour for swimming lessons and $20 registration fee. If you make $52 one day, how many hours did you spend teaching lessons? Algebra
Answer:
4 hrs
Step-by-step explanation:
Let h be the number of hours spent teaching lessons
Then 8h is the amount earned from swimming lessons
Total amount earned = amount from swimming lessons + $20 registration fee
Total amount earned = $52
Therefore, 52=8h+20
32=8h
h=4 hrs (Answer)
Each of a regular polygon is 140°,find the number of the sides that ghe polygon has
Answer:
the answer should be 360/36=10 sides
Step-by-step explanation:
A regular polygon is 144 deg the exterior angle is 36 deg.
Answer:
9 sides
Step-by-step explanation:
Internal angles of the regular polygon have a property, sum of interior angles is equal to:
sum = (n-2)*180°n sides each interior angle equal to 140°, then
sum = 140°nComparing the two equations:
(n-2)*180= 140n180n - 360 = 140n40n = 360n = 360/40n = 9The polygon has 9 sides
is every equation a function, true or false?
∠A and \angle B∠B are vertical angles. If m\angle A=(5x+5)^{\circ}∠A=(5x+5)
∘
and m\angle B=(4x+29)^{\circ}∠B=(4x+29)
∘
, then find the measure of \angle A∠A.
If A and B are vertical angles, then they are congruent, so their measures are equal.
This means
(5x + 5)º = (4x + 29)º
5x + 5 = 4x + 29
x = 24
Then angle A has measure (5*24 + 5)º = 125º.
Answer:
m<A = 115

Solve the given inequality.
4.2x > 6.3
Answer:
x > 1.5
Step-by-step explanation:
In order to solve for x, we must isolate x on one side of the inequality.
[tex]4.2x > 6.3[/tex]
x is being multiplied by 4.2 The inverse of multiplication is division. Divide both sides of the equation by 4.2
[tex]\frac{4.2x}{4.2} >\frac{6.3}{4.2}[/tex]
[tex]x> \frac{6.3}{4.2}[/tex]
[tex]x> 1.5[/tex]
The solution to the inequality 4.2x > 6.3 is x>1.5
Answer:
[tex]\huge\boxed{x>1\dfrac{1}{2}\to x\in\left(1\dfrac{1}{2},\ \infty\right)}[/tex]
Step-by-step explanation:
[tex]4.2x>6.3\qquad/\text{divide both sides by 4.2}\\\\\dfrac{4.2x}{4.2}>\dfrac{6.3}{4.2}\\\\x>\dfrac{6.3\cdot10}{4.2\cdot10}\\\\x>\dfrac{63:21}{42:21}\\\\x>\dfrac{3}{2}\\\\x>1\dfrac{1}{2}[/tex]
I need D and E for number 1 and all 3 for number 2
Answer:
E: 20/(7-2)+(5^2*3)
D: (24+16)/(8-4)
sorry, didn’t do q2
Step-by-step explanation:
E (q1)
20/(7-2)+(5^2*3) is 79
20/5 plus 25*3 is 79
4 plus 75 is 79
D (q1)
(24+16)/(8-4) is 10....... 40/4 is 10

Which is the solution to the equation represented by the model below
Answer:
Third option, [tex]x=2[/tex]
Step-by-step explanation:
By observation, we can infer that
[tex]3x+8=4x+6[/tex].
Subtract 8 from both sides:
[tex]3x+8-8=4x+6-8[/tex]
[tex]3x=4x-2[/tex]
Subtract 4x from both sides:
[tex]3x-4x=4x-2-4x[/tex]
[tex]-x=-2[/tex]
Divide both sides by -1:
[tex]\frac{-x}{-1}=\frac{-2}{-1}[/tex]
[tex]x=2[/tex]

Assume that y varies directly with x, then solve.
if y=-6.6 when x=9.9, find y when x=6.6
Answer:
y = - 4.4
Step-by-step explanation:
Given that t varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 6.6 when x = 9.9 , that is
- 6.6 = 9.9k ( divide both sides by 9.9 )
k = [tex]\frac{-6.6}{9.9}[/tex] = - [tex]\frac{2}{3}[/tex]
y = - [tex]\frac{2}{3}[/tex] k ← equation of variation
When x = 6.6, then
y = - [tex]\frac{2}{3}[/tex] × 6.6 = - 2 × 2.2 = - 4.4
