Rita wants to save her babysitting money to buy a $249.99 camera. she makes $64.33 a month, and her fixed expenses are $34.50 a month. how do you think she should budget for the camera?

Answers

I’m not 100% sure with this one!!!! But my guess is if you take 20%. So then it would be 14.5. (I’m not 100% sure but maybe 80%)

The number of months in which Rita has a budget to buy a camera is 8 and a half months if Rita wants to save her babysitting money to buy a $249.99 camera.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Rita wants to save her babysitting money to buy a $249.99 camera. she makes $64.33 a month, and her fixed expenses are $34.50 a month.

Let x be the number of months in which Rita has a budget to buy a camera.

The linear equation in one variable can be framed as follows:

(64.33 - 34.50)x = 249.99

29.83x = 249.99

x = 8.38 = 8.5

Thus, the number of months in which Rita has a budget to buy a camera is 8 and a half months if Rita wants to save her babysitting money to buy a $249.99 camera.

There are 26 counters in a bag. 5 of the counters are pink. 10 of the counters are blue. the rest of the counters are white. jan puts some more pink counters into the bag. she then takes some blue counters out of the bag. after she has done this there are still 26 counters in the bag. jan then takes at random a counter from the bag. the probability that she takes a pink counter is 1/2 what is the probability that she takes a blue counter?

Answers

The probability of picking a blue counter from the bag is 1 / 13.

What is the probability?

The number of counters initially in the bag:

white counters = 26 - 10 - 5 = 11 pink counters = 5 blue counters = 10

The number of counters now in the bag:

white counters = 11pink counters = (5 + x) / 26 = 1/2

13/26

x = 13 - 5 = 8

blue counters = 26 - 13 - 11 = 2

Probability of picking a blue counter = number of blue counters / total number of counters

2/26 = 1 / 13

Answers

By using the Pythagorean theorem, we conclude that side x measures (5/2)*√3 units.

How to find the length of side x?

In the image, we can see that the equilateral triangle can be divided into two right triangles.

If each side of the equilateral triangle measures 5 units, then for the right triangles we will have that the hypotenuse measures 5 units, and the bottom side measures half of that: 2.5 units.

Now remember the Pythagorean theorem. It says that the sum of the squares of the cathetus is equal to the square of the hypotenuse.  Then we will have:

[tex]x^2 + 2.5^2 = 5^2[/tex]

[tex]x = \sqrt{5^2 - 2.5^2} = \frac{5}{2}\sqrt{3}[/tex]

Then we conclude that side x measures (5/2)*√3 units.

The probability of spinning am even number is 40%. What is the probability of not spinning an even number, written as a decimal

Answers

Answer:

That would be 0.6 that means 60 percent.

Answer:

Probability of not spinning an even number is 0.6

Step-by-step explanation:

Total probability is 100 since it represented by %.

Therefore if 40% is the probability of spinning an even number then that of not spinning an even number is simply

100% - 40% = 60%

Expressing 60% as a decimal gives us 0.6

Find an integer x such that x, 56, 65 is a pythagorean triple

Answers

Answer:

  x = 33

Step-by-step explanation:

The three numbers will be a Pythagorean triple if the sum of the squares of the first two is equal to the square of the third.

__

We want ...

  x² +56² = 65²

  x² = 65² -56² = 4225 -3136 = 1089

  x = √1089 = 33

The value x = 33 will make (33, 56, 65) a Pythagorean triple.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a standard-position angle determined by the point (x, y).

The point is (9, 12)

From the Pythagoras theorem, we can find the hypotenuse(h):

h  = √(9²+12²)

h = 15

cscθ = hypotenuse/opposite = 15/12 = 5/4

secθ = hypotenuse/adjacent = 15/9 = 5/3

Thus, the measure of the cscθ and secθ are 5/4 and 5/3 respectively option (A) is correct.

Answers

The complete factor of the expression 9x² + 3x - 2 is (3x - 1)(3x + 2)

How to determine the complete factorization?

The expression is given as:

9x² + 3x - 2

Expand the equation

9x² + 3x - 2 = 9x² + 6x - 3x - 2

Factorize the expression

9x² + 3x - 2 = 3x(3x + 2) - 1(3x + 2)

Factor out 3x + 2

9x² + 3x - 2 = (3x - 1)(3x + 2)

Hence, the complete factor of the expression 9x² + 3x - 2 is (3x - 1)(3x + 2)

Which of the following equations represents a line that is parallel to the line with equation y = 3/2*x-7/4?
(A) 6x+4y=8
(B) -6x + 4y = 11
(C) x-2y=-4
(D) 3x+2y=7​

Answers

Answer:

(B) -6x + 4y = 11

Step-by-step explanation:

Two lines are parallel if they have the same slope

In the line equation, y = mx + b, m = slope

For y = 3/2*x - 7/4, slope = 3/2

(B) can be written as

4y = 6x +11

Dividing by 4 on both sides gives y = 6/4*x + 11/4 which is 3/2*x + 11/4 so the coefficient of x (the slope) is 3/2 which is the slope of the line in the question

Using same strategies for the other lines, you will see
(A) has slope -3/2

(C) has slope 1/2

(D) has slope -3/2

Answer:

G.31

Step-by-step explanation:

when n = 31

1116n = 1116*31 = 34596

34596 is square of 186.

= 186^2

= 34596

and other values (24,28,33) of n does not give square during 1,116n but 31 gives.

Hence, 31 is the possible value of n for which 1,116n is the square of an integer(186).

The dance committee hired a DJ for the fall dance. The DJ charges
$125 per hour in addition to $55 for an assistant. The committee
wants to keep the total cost under $600. Which inequality represents
the maximum amount of hours the DJ will play at the dance?

Answers

Answer: 4 hours

Step-by-step explanation:

4 Hours

Explanation:

Make h = hours

You add the $55 extra cost for the assistant

$125h + $55 = $555

Use additive inverse to isolate the term with the variable

$125h + $55 - $55 = $555 - $55

Use multiplicative inverse to isolate the variable

[tex]\frac{125h}{125}[/tex] = [tex]\frac{500}{125}[/tex]

Hours would be: 4 Hours.

[tex]A = \frac{3\sqrt{3}}{2}l^2\\384\sqrt{3} = \frac{3\sqrt{3}}{2}l^2\\384 = \frac{3}{2}l^2\\256 = l^2\\16 = l[/tex]

Does anybody understand this? QSRT is a Rectangle and SQR=55

Answers

Answer:

  90°; 55°; 35°; 110°; 70°

Step-by-step explanation:

A rectangle has corner angles that are 90°. When the corner angle is divided into two parts, the total of the parts is 90°.

Each of the triangles is isosceles. The figure is symmetrical about its center.

An exterior angle to a triangle is equal to the sum of the remote interior angles.

__

∠SRT = 90° . . . . a corner angle

∠STR = 55° . . . . symmetrical to the given angle

∠QRS = 180° -55° -90° = 35° . . . . sum of angles in ΔQRS is 180°

∠QPT = 2×55° = 110° . . . . exterior angle to ΔQPS; ∠QSP =∠SQP

∠TPR = 180° -110° = 70° . . . . forms a linear pair with ∠QPT

_____

There are numerous ways to figure any or all of these angles. They come down to the fundamentals: angles in a triangle total 180°; angles that form a line total 180°; corner angles of a rectangle are 90°. Base angles of an isosceles triangle are congruent.

The exterior angle rule derives from the sum of angles in a triangle and on a line both being 180°.
