Work out the value of x.​

Answer: 77 degrees

Step-by-step explanation:

Ratio of the angles = 5 : 7 : 9 = 5x : 7x : 9x

5x + 7x + 9x = 21x

180 = 21x

x = 180/21

Largest angle = 9x,

= 9 * 180/21

= 540/7

540/7 = 77.14285...

Which is rounded to 77 degrees :>

Samuel pay 5.81 for the 3 bottles of juice.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

Samuel buys 3 bottles of juice that each have an original price of 2.80.

And, He uses a coupon for 35% off. Then, he is changed sales tax at a rate of 6.5%.

Here, The original cost of 3 bottles of juice = 3 × 2.80

                                                                   = 8.40

Now, He uses a coupon for 35% off.

Hence, The off price = 35% of 8.40

                                = 35/100 × 8.40

                                = 2.94

So, The amount of 3 bottles of juice = 8.40 - 2.94

                                                        = 5.46

And, He is changed sales tax at a rate of 6.5%.

Thus, The sales tax on bottles = 6.5% of 5.46

                                               = 6.5/100 × 5.46

                                               = 0.35

Thus, The actual amount of 3 bottles of juice = 5.46 + 0.35

                                                                     = 5.81

The mean is 24.2 and the standard deviation is 8.7.

The mean amount of revenue each car generates can be calculated by multiplying the mean number of hours parked by the cost per hour. To find the mean number of hours parked, we need to multiply each possible number of hours by its probability and add them up.

E(X) = (1 * 0.229) + (2 * 0.113) + (3 * 0.114) + (4 * 0.076) + (5 * 0.052) + (6 * 0.027) + (7 * 0.031) = 4.84 hours

So, the mean revenue is 4.84 * 5 = 24.2 dollars

The standard deviation of the revenue can be calculated by finding the standard deviation of the number of hours parked and then multiplying by the cost per hour.

SD(X) = sqrt( (1^2 * 0.229) + (2^2 * 0.113) + (3^2 * 0.114) + (4^2 * 0.076) + (5^2 * 0.052) + (6^2 * 0.027) + (7^2 * 0.031) - (4.84)^2) = 1.74 hours

So, the standard deviation of the revenue is 1.74 * 5 = 8.7 dollars.

Broderick needs $610.00 in his account to cover his checks.

We know that the balance Boderick has is $420.

First, we will calculate the total amount of the 6 deposits made by Broderick each of $35.50 deposit as follows -

$35.50 x 6 = $213.00

Hence, the total amount of the 6 deposits made by Broderick is $213.00

Next, we will calculate the total amount of the 4 checks he needs to write-

$310.75 x 4 = $1243.00

Hence, the total amount of the 4 checks that Broderick needs to write is $1243.00

Now we will find the final balance of Broderick's account after all the deposits and check withdrawals. We can do this by adding the total amount of the deposits to his initial balance and subtracting the total amount of the checks as follows-

$420.00 + $213.00 - $1243.00 = -$610.00

The correct option regarding the median of each data-set is given as follows:

The median of the number of hours spent volunteering by each student in Sophia's homeroom is less than the median of the number of hours spent volunteering by each student in the tenth-grade class.

The median of a data-set is the middle value of a data-set, the value of which 50% of the measures are less than and 50% of the measures are greater than. Hence, the median also represents the 50th percentile of a data-set.

For Sophia's Homeroom, the total number of students is given as follows:

4 + 9 + 3 + 7 = 23.

Hence the median is the 12th element, which is on the interval 10-19.

For the Tenth Grade class, the total number of students is given as follows:

42 + 38 + 65 + 40 = 185.

Hence the median is the element at the position (185 + 1)/2 = 93, which is on the interval 20-29.

Hence the median is the 12th element, which is on the interval 10-19.

From the triangle KLM inside the circle, the value of KM is calculated. And, the value is 1.2079.

A triangle is a polygon made up of three vertices, three angles, and three sides. First, draw a circle with a midpoint represented by O. Then, draw a triangle KLM inside a circle. Now, construct the line segments KO, MO, and LO because they form the circle's radius.

Given that KL = LM. Since two sides of the triangle KLM is equal, it is an isosceles triangle. Also, ∠K=∠M=17°. The total angle of this triangle is 180°. Then, ∠L=180°-17°-17°=146°.

Half the angle L is 73°. Then, ∠KLO=∠MLO=73°.

Consider triangle KLO, this triangle is also isosceles because KO = LO. Then, ∠KLO=∠OKL=73°.

Now, ∠KOL is calculated as follows from the triangle KLO,

[tex]\begin{aligned}\angle KOL&=180^{\circ}-73^{\circ}-73^{\circ}\\&=34^{\circ}\end{aligned}[/tex]

Similarly, consider triangle MLO, this triangle is also isosceles because LO=MO. Then, ∠MLO=∠OML=73°.

Now, ∠LOM is calculated as follows from the triangle MLO,

[tex]\begin{aligned}\angle LOM&=180^{\circ}-73^{\circ}-73^{\circ}\\&=34^{\circ}\end{aligned}[/tex]

Then,

[tex]\begin{aligned}\angle KOM&=\angle KOL+\angle LOM\\&=34^{\circ}+34^{\circ}\\&=68^{\circ}\end{aligned}[/tex]

Using, the cosine law of the triangle KOM, we get,

[tex]\begin{aligned}(KM)^2&=1.08^2+1.08^2-2(1.08)(1.08)\cos 68^{\circ}\\&=2.3328-2.3328(\cos 68^{\circ})\\&=2.3328(1-\cos 68^{\circ})\\&=2.3328(0.6254)\\&=1.4589\\KM&=\sqrt{1.4589}\\&=1.2079\end{aligned}[/tex]

Answer:

Step-by-step explanation:

To solve this equation, we first need to get all the terms on one side of the equation by subtracting 3x from both sides:

4x^2 - 7x - 3x = 24

Simplifying, we get:

4x^2 - 10x = 24

Now, we can factor out the GCF (Greatest common factor) on the left side of the equation:

2x(2x-5) = 24

Now we can divide both sides of the equation by 2x(2x-5) to get the solutions for x:

x = 5/2 , x = 0

So the solutions of the equation 4x^2 - 7x = 3x + 24 are x=5/2 and x=0

After inspecting the graph, when x=0  y is 6 so the constant is +6 which is Positive
