Answer:

x = 55

y = 20

Step-by-step explanation:

Angles on a straight line sum to 180°.

Finding x

⇒ 75° + (2x - 5)° = 180°

⇒ 75 + 2x - 5 = 180

⇒ 2x + 70 = 180

⇒ 2x + 70 - 70 = 180 - 70

⇒ 2x = 110

⇒ 2x ÷ 2 = 110 ÷ 2

⇒ x = 55

Finding y

⇒ 75° + (4y + 25)° = 180°

⇒ 75 + 4y + 25 = 180

⇒ 4y + 100 = 180

⇒ 4y + 100 - 100 = 180 - 100

⇒ 4y = 80

⇒ 4y ÷ 4 = 80 ÷ 4

⇒ y = 20

[tex]7x^2+7y^2-28x+42y-35=0 \\ \\ x^2 +y^2-4x+6y-5=0 \\ \\ x^2+y^2-4x+6y=5 \\ \\ x^2-4x+4+y^2+6y+9=18 \\ \\ \boxed{(x-2)^2+(y+3)^2=18}[/tex]

Set equation and solve for x:

The numerical value of p in the equation p = mv, when m = 5 and v = 23 is 115.

Given the equation in the question;

To determine the value of p, plug in the values of m and v and simplify.

p = mv

Plug in m = 5 and v = 23

p = 5 × 23

Multiply 5 and 23

p = 115

Therefore, the value of p is 115.

The table that represents this relationship regarding the volume is table D.

From the information, the approximate volume in milliliters, m, for a volume of f fluid ounces is equal to 29.57 times the value of f.

Therefore, when f is 1, the millimeters will be:

= 1 × 29.57

= 29.57

When f is 2, the millimeters will be:

= 2 × 29.57

= 59.14

When f is 3, the millimeters will be:

= 3 ×29.57

= 88.71

When f is 4, the millimeters will be:

= 4 × 29.57

= 118.28

Therefore the correct option is table D.

1/9 +2/3=1/9+ 6/9 =7/9

7/9 +5/18= 14/18 + 5/18 = 19/18

According to the solving the probability will be 0.159.

The area of mathematics known as probability deals with numerical assessments of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. In addition to being expressed in percentages ranging from 0% to 100%, probabilities can also be expressed as proportions between 0 and 1.

The incidence rate is = 0.2%  or 0.002

The false negative rate is = 8%  or 0.008

The false positive rate is = 1%  or 0.001

The probability is

0.01*(1-0.002) + 0.95*0.002

= 0.00998 + 0.0019 = 0.01188

Probability that a person who tests positive actually has the disease would be represented as:

Let the probability be represented by = p

p * 0.01188 = 0.95 * 0.002

p = 0.0019/0.01188

p = 0.159

Hence, probability is 0.159

According to the solving the probability will be 0.159.

It would be unusual for this  sample of 800 to contain 528 jawbreakers that weigh more than .4 ounces, using the binomial distribution, as 528 is more than 2.5 standard deviations above the mean.

The binomial distribution gives the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The mean of the binomial distribution is of:

E(X) = np.

The standard deviation of the binomial distribution is of:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

The unusual measures are the ones that are more than 2.5 standard deviations from the mean.

The values of the parameters in this problem are given as follows:

p = 0.6, n = 800.

Hence the mean and the standard deviation are given as follows:

The upper bound of usual values is of:

480 + 2.5 x 13.86 = 514.65.

The graph is a relation that represents the relationship between two variables on the x and y axis .

In the question ,

Harper's data of time of day and the temperature, in degrees Fahrenheit is given,

the temperature at 6 a.m. = 58° F

for the next 3 hours the temperature rose 4° each hour means

in 3 hours it will rise 12°

So , the temperature at 9 a.m. = 70° F

For the next 5 hours, it rose 1° per hour which means

in 5 hours it will rise 5°

So , the temperature at 2 p.m. = 75° F

The temperature then stayed steady until 6 p.m. which means

temperature at 6 p.m. = 75° F

For the next 2 hours, the temperature dropped 1° per hour , which means

temperature at 8 p.m. = 73° F

the temperature at midnight = 70° F

So , from the above data the graph is shown below .

After simplifying the expression, the value of y is 4.53.

In the given question,

We have to solve for y.

The given expression is 116° +15y - 4=180.

To solve for y we simplify the expression.

The expression is 116° +15y - 4=180

Now simplifying the expression.

Add 4 on both side

116° +15y - 4+4=180+4

116° +15y=184

Subtract 116 on both side

116° +15y-116°=184-116°

Simplifying

15y=184-116°

15y = 68

Divide by 15 on both side

15/15 y=68/15

y=4.53

Hence, the value of y is 4.53.

The theorem that proves that the triangles are congruent is the Hypotenuse-leg (HL) Congruence Theorem. The correct option is the first option - HL Congruence Theorem

From the question, we are to determine by what theorem of postulate the triangles can be proven congruent.

From the Hypotenuse-leg theorem which states that "if the hypotenuse and a leg of a right triangle are each congruent with the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent".

From the given diagram, we can observe that the hypotenuse of the first triangle is congruent to the hypotenuse of the second triangle. Likewise, we can observe that one of the legs of the first triangle is congruent to the one of the legs of the other triangle.

Hence, the triangles are congruent by the Hypotenuse-leg theorem.

5.75 liters of 3 percent hydrogen peroxide solution are included by the company in the container.

A measurement used to determine a number's value out of 100 is the percentage.

Hydrogen peroxide solutions in various containers have concentrations of 35% and 3%.

Since the corporation wants an 8-liter container with a 12% hydrogen peroxide concentration.

Use mixture and allegation property,

Using the double-declining-balance method of depreciation, the completion of the table as shown is as follows:

Year Cost   Accumulated   Book Value  Depreciation Accumulated  Book

                   Depreciation        B.O.Y         Expense      Depreciation   Value

                        B.O.Y                                                               E.O.Y       E.O.Y

3   $29,000   $18,560          $10,440           $4,176           $22,736   $6,264

The double-declining-balance method is one of the depreciation methods in use, but it allocates more cost to the earlier years of the asset's life.

This depreciation method uses twice the straight-line rate, which is computed as the product of 100/estimated useful life multiplied by 2.

For each year's depreciation expense, the double rate is applied at the end of the year's balance.

For the last year, the difference between the previous year's ending balance and the residual value is taken as the depreciation expense.

Auto  = $29,000

Estimated useful life = 5 years

Residual = $2,000

Depreciable amount = $27,000 ($29,000 - $2,000)

Straight-line depreciation rate = 20% (100/5)

Double-declining depreciation rate = 40% (20% x 2)

1st year = $11,600 ($29,000 x 40%)

2nd year = $6,960 ($17,400 x 40%)

3rd year =  $4,176 ($10,440 x 40%)

4th year = $2,506 ($6,264  x 40%)
