Six student government officers want to go to the state convention. It will cost them $100 for registration, $380 for transportation and food, and $54 per person for the hotel. There is $500 budgeted for the convention in the student government savings account. They can earn the rest of the money they need by having a car wash. If they charge $5 per car, how many cars must they wash in order to have enough money to pay for the trip?

Answer:

Step-by-step explanation:

it can be simplified to [tex]\frac{sec \theta}{cot\theta+tan\theta} =sin\theta[/tex]  . if you multiply each side by the denominator, it becomes [tex]sec\theta=\frac{sin^2\theta}{cos\theta} + cos\theta[/tex] since [tex]tan\theta=\frac{sin\theta}{cos\theta}[/tex] and cotan is the reciprocal of that. Because [tex]sec\theta=\frac{1}{cos\theta}[/tex] so multiplying each side gives [tex]1=sin^2\theta+cos^2\theta[/tex], and [tex]sin^2\theta+cos^2\theta[/tex] is equal to 1.

The biggest problem with the results of this research study is B. Lack of realism.

It should be noted that when an experiment's procedures, participants, or setting are unrealistic. The ability of researchers to apply the findings of an experiment to the situations that hold the most interest may be constrained by a lack of realism.

Answer:

M∠2 = 37°

M∠3 = 143°

M∠4 = 37°

Step-by-step explanation:

∠3 is the complete opposite of ∠1

143° + 143° = 286°

there is 360° in a full circle or a repeating angle (aka the scissors)

360°-286°=74°

since ∠2 and ∠4 is opposite of each other

74°÷2=37°

Answer:

[tex]m \angle 2= \boxed{37}\;^{\circ}\\\\m \angle 3= \boxed{143}\;^{\circ}\\\\m \angle 4= \boxed{37}\;^{\circ}[/tex]

Step-by-step explanation:

Angles on a straight line sum to 180°.

⇒ m∠1 + m∠2 = 180°

⇒ 143° + m∠2 = 180°

⇒ m∠2 = 37°

Vertical Angle Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Applying the Vertical Angle Theorem:

Considering the definition of an equation and the way to solve it, the number of monthly movies watched that would make the two plans have an equal monthly cost is 26.

An equation is an algebraic equality in which there are unknowns with unknown value. The unknown represents the number, if any, that makes the equality true. This unknown number is the solution of the equation.

This is, the solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

Being "x" the number of monthly movies watched, you know that:

If the two plans have an equal monthly cost, the equation in this case is:

A= B

34 + 2x= 8 + 3x

Solving:

34 - 8= 3x - 2x

26= x

Finally, 26 monthly movies watched would make the two plans have an equal monthly cost.

By using subtraction, we get that, the total yardage for the drive was that they gained 7 yards.

We are given that:

On a drive,

A football team first gains = 3 yards.

Then it lost = 11 yards.

Then it again gained = 15 yards.

We need to find its total yardage.

For this, we will subtract the yards lost from the yards gained by the team.

So, we get that:

total yardage = 3 + 15 - 11

total yardage = 18 - 11

total yardage = 7 yards.

Therefore, by using subtraction, we get that, the total yardage for the drive was that they gained 7 yards.

We have a translation of 3 units to the left and 4 units upwards.

To find the translation, we only need to look at one of the vertices of the triangle.

We can see that the coordinates of B are (4, 1), while the coordinates of the translated point B' are (1, 5)

The translation is given by the difference:

(1, 5) - (4, 1) = (1 - 4, 5 - 1) = (-3, 4)

Answer:

9  57/ 100

Step-by-step explanation:o convert the decimal 9.57 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

9.57 = 9.57/ 1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,

9.57 / 1

= (9.57 × 100)

(1 × 100)

= 9 57/ 100

.

(This fraction is alread reduced, We can't reduce it any further).

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 9 57/ 100

The area of the reservoir in standard form is 1.8 × 10⁴ square miles

The volume of the reservoir in scientific notation is 2.8 × 10⁴ cubic miles

From the question, we are to determine the area of the reservoir in standard form and the volume of the reservoir in scientific notation

Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form

Thus,

To write a number in standard form, we will write the number as a product of a number between 1.0 and 10.0 and a power of 10

Answer:

To one decimal place, x = 7.7 cm

Step-by-step explanation:

Let y equal BD.

Since AD is a bisector of angle BAC, angle DAB is 17°.

tan(17°) = y/21, so y = 21 tan(17°)

tan(34°) = (x + 21 tan(17°))/21

21 tan(34°) = x + 21 tan(17°)

x = 21(tan(34°) - tan(17°)) = 7.7 cm

Ok, so you want to earn a total of $31,836, and he has a fixed salary of $30,572, so the missing amount is:

$31,836 - $30,572 = $1,264

Now, we know that you make a commission of the 5% of what you sell, so if X is what you sell, then to make the desired salary X must be:

X*0.05 = $1,264

Pies left after Red Riding Hood ate 2: [(0.5x - 0.5) - 2]

Pie after she gave the wolf 1/3 ; (1 - 1/3) × [(0.5x - 0.5) - 2]

Multiply both sides of the equation by 3/2.

[(0.5x - 0.5) - 2] = 12

Add 2 to both sides of the equation: 0.5x - 0.5 = 12 + 2

0.5x - 0.5 = 12

Substituting P=26 and adding like terms,

26 = 10 + 4z

Subtracting -10 to both sides:

26 - 10 = 10 - 10 + 4z
