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

Answers

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)

d=gh - f gives the distance d of a bird from its nest after flying 5 hours. Find a formula for h in terms of d A d-f​

Answers

Answer:

d+f/g=h

Step-by-step explanation

I didn't really understand what the part about A d-f thing. But I recently got this problem.

You start off with d=gh-f. Then you want to isolate the variable so you add f to both sides. Leaving, d+f= gh. Then you divide g from both sides and then get d+f/g = h.

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.

-x^2 = -36

Answers

To find the inverse function, swap x x and y y , and solve the resulting equation for x x . If the initial function is not one-to-one, then there will be more than one inverse. So, swap the variables:

y=−x2−36 y = − x 2 − 36

becomes

x=−y2−36 x = − y 2 − 36 .

Now, solve the equation

x=−y2−36 x = − y 2 − 36 for y y .

y=−x−36‾‾‾‾‾‾‾‾√ y = − x − 36y=−x−36‾‾‾‾‾‾‾‾√ y = − − x − 36

What is the value of x in the equation 0.3x = 12?

Answers

Answer:

You divide 0.3 by 12 if you don’t want a decimal do it the other way around the answer is x=40

Step-by-step explanation:

The value of x that satisfies the equation 0.3x = 12 is 40.

We have,

To find the value of x in the equation 0.3x = 12, we need to isolate x on one side of the equation.

We can do this by dividing both sides of the equation by 0.3, which will cancel out the coefficient of x on the left side:

(0.3x) / 0.3 = 12 / 0.3

Simplifying this equation gives:

x = 40

Thus,

The value of x that satisfies the equation 0.3x = 12 is 40.

∠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.

Answers

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.

Each of a regular polygon is 140°,find the number of the sides that ghe polygon has​

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°n

Comparing the two equations:

(n-2)*180= 140n180n - 360 = 140n40n = 360n = 360/40n = 9

What is the value of x in the equation 4x - 2(x + 3) = 8?
A x = 1
B. X = 2.5
C x = 3.5
D. x = 7

Answers

Answer:

x = 7

Step-by-step explanation:

The given equation is 4x - 2(x + 3) = 8. We need to find the value of x. The steps are as follows :

Firstly opening the bracket on the LHS,

4x -2x-6 = 8

Adding like terms together. So,

2x = 8+6

2x = 14

x = 7

So, the value of x is 7. Hence, the correct option is (d).

(a) An angle measures 64°. What is the measure of its complement?



(b) An angle measures 145º. What is the measure of its supplement?

Answers

Answer:

(a) 26 degrees

(b) 35 degrees

Step-by-step explanation:

(a) complementary angles add up to 90 degrees, therefore the complementary angle to 64 degrees would be 90 - 64, or 26 degrees.

(b) supplementary angles add up to 180 degrees, therefore the supplementary angle to 145 degrees would be 180 - 145, or 35 degrees.

Find the exact sum of the arithmetic series

6+3.8+⋯−29.2

Answers

Answer:

-197.2

Step-by-step explanation:

Since it is arithmetic series, first find the difference d between the two know series.

3.8 - 6 = - 2.2

d = -2.2

a = 6

Tn = -29.2

Looking for the n term, use the linear method.

Tn = a+( n - 1)d

Substitute all the parameters

-29.2 = 6+( n - 1 ) -2.2

-29.2 = 6 - 2.2n + 2.2

- 29.2 = 8.2 - 2.2n

-29.2 - 8.2 = - 2.2n

-37.4 = -2.2n

n = 37.4/ 2.2

n = 17 terms.

To Find the exact sum of the arithmetic series, use the sum formula below

Sm = n/2( 2a + (n - 1)d)

Sm = 17/2( 2 × 6 + ( 17 - 1 ) -2.2

Sm = 17/2(12 - 35.2)

Sm = 8.5( - 23.2)

Sm = - 197.2

Therefore, the exact sum of the arithmetic series is -197.2
