The measure of x = 64°

The opposing angles created by the intersection of two lines are known as vertical angles or vertically opposed angles. A pair of angles that are vertically opposed to one another are always equal.

Here we have

Three lines are intersected and formed a triangle  

Let's assume that the triangle formed is ΔABC

In ΔABC,  ∠C = 34°  

Since Vertical opposite angles are equal

=> ∠B = 30°  

As we know the sum of angles in a triangle = 180°

=> ∠A + ∠B + ∠C = 180°

=> ∠A = 180° -  30° - 34°  

=> ∠A = 116

From the line CL [ observe the given picture ]  

=> ∠A + x = 180°

=> 116° + x = 180°

=> x = 180° - 116°

=> x = 64°  

Therefore,

The measure of x = 64°

a) The equation is 10p + 80 = 180 and p = 10.

b) The three angles are 90°, 37°, 53°.

What is an equation?

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Given that, the angles of the triangles are 53°, 2p + 17°, and 8p + 10°.

The sum of all angles of a triangle is  53° + 2p + 17° + 8p + 10° = 80 + 10p

The sum of all angles of a triangle is 180°.

Therefore,

80 + 10p = 180

Subtract 80 from both sides:

10p = 100

divide both sides by 10:

p = 10.

Putting p = 10 in 2p + 17°, and 8p + 10°:

2p + 17° = 20° + 17° = 37°

8p + 10° = 80° + 10° = 90°

The solution of a compound inequality is the common region or intersection region of two inequalities.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

A sentence having two inequality statements connected by the words 'or' Or 'and' is referred to as a compound inequality. The conjunction "and" denotes the simultaneous truth of both statements in the compound sentence.

For example, if in a compound inequality we get x > 3 and x > 5 so the final conclusion is x > 5.

Step-by-step explanation:

The value of r is 45 and the value of s is 29

From the question, we are to solve the parallelogram for the missing variables.

The missing variables are r and s

Since opposite angles of a parallelogram are equal, we can write that

(r - 10)° = (3r - 100)°

Solve for r

r - 10 = 3r - 100

-10 + 100 = 3r - r

90 = 2r

r = 90/2

r = 45

Also,

We can write that

(5s)° = (4r - 35)°

Substitute the value of r and solve for s

5s = 4(45) - 35

5s = 180 - 35

5s = 145

s = 145/5

s = 29

Hence, r = 45, s = 29

Answer:

Therefore, the value of k is 1.

Step-by-step explanation:

Vertical angles are pairs of angles that are opposite each other and are formed by two intersecting lines. If one angle measures 160°, the other angle must measure 180° - 160° = 20°. Therefore, if the other angle measures (3k + 61)°, we can set up the equation 20 = 3k + 61. Solving for k, we get k = -41. However, since the value of k must be a positive integer, the only possible value of k is k = 1. Therefore, the value of k is 1.

Answer:

25.5 inches.

Step-by-step explanation:

To find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

In this case, we have a right triangle with legs of length 19 inches and 17 inches. The length of the hypotenuse is the square root of the sum of the squares of the other two sides. We can calculate this as follows:

hypotenuse = sqrt(19^2 + 17^2)

hypotenuse = sqrt(361 + 289)

hypotenuse = sqrt(650)

hypotenuse = 25.495097568 inches

Rounding to the nearest tenth, the length of the hypotenuse is 25.5 inches.

What is an equation?

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

1.a

Compute the vale of  60% of 400.

Using the formula a% = a/100

60% of 400 = 60/100 of 400

Replace of by multiplication:

60% of 400 = (60/100) × 400

60% of 400 = 240.

1b.

Compute the vale of  60% of 200.

Using the formula a% = a/100

60% of 200 = 60/100 of 200

Replace of by multiplication:

60% of 200 = (60/100) ×2 00

60% of 400 = 120.

1c.

Compute the vale of  60% of 120.

Using the formula a% = a/100

60% of 120 = 60/100 of 120

Replace of by multiplication:

60% of 120 = (60/100) × 120

60% of 400 = 72.

2.

Given that 60% of x is 87.

Compute the vale of  60% of x.

Using the formula a% = a/100

60% of x = 60/100 of x

Replace of by multiplication:

60% of x = (60/100) × x

60% of x = 0.6x

Therefore the relationship is 0.6x = 87

Now divide both sides by 0.6:

x = 87/0.6

x = 145.

3a.

Given that 60% of c is 43.2.

Compute the vale of  60% of c.

Using the formula a% = a/100

60% of c = 60/100 of c

Replace of by multiplication:

60% of c = (60/100) × c

60% of c = 0.6c

Therefore the relationship is 0.6c = 43.2

Now divide both sides by 0.6:

c = 43.2/0.6

c =72.

3b.

Given that 38% of e is 190.

Compute the vale of  38% of e.

Using the formula a% = a/100

38% of e = 38/100 of e

Replace of by multiplication:

38% of e = (38/100) × e

38% of e = 0.38e

Therefore the relationship is 0.38e = 190

Now divide both sides by 0.38:

e = 190/0.38

e = 500.

Answer:

The prices where the revenue is zero are $x = 0 and $x = 125.

When x = 0, the revenue is 0 since the function is equal to zero (R(0) = -40(0)^2 + 5000(0) = 0).

When x = 125, the revenue is 0 since the coefficient of the x^2 term is negative and the coefficient of the x term is positive. Since the equation is equal to zero, the two terms must cancel each other out, resulting in zero revenue (R(125) = -40(125)^2 + 5000(125) = 0).

Step-by-step explanation:

The answer for the first shape would be 24cm^2.

The answer for the second shape would be 20cm^2.

The answer for the third shape would be 30cm^2. "30".

What are Shapes?

A shape in geometry can be characterized as an object's form, outline, outer border, or outer surface.

The first shape seems to be scaling up. From 3cm to 12cm. So for this you need to multiply. Using the formula that I gave you last time.

3cm times ___ = 12cm. 4 fits in there,

therefore 6cm^2 times 4 = 24cm^2.

The answer for the first one would be 24cm^2. "24" in the blank.

The second shape seems to be scaling down. From 16cm to 8cm. So for this you need to divide.

16cm divided by ___ = 8cm. 2 fits in there,

therefore 40cm^2 divided 2 = 20cm^2.

The answer for the second one would be 20cm^2. "20" in the blank.

The third shape seems to be scaling up.

From 3cm to 4.5cm.

So for this you need to multiply. 3cm times ___ = 4.5cm.

Now since we're dealing with decimals, not whole numbers this time you can't really use guess and check as efficiently. So you do the opposite operation, which in this case the opposite of multiplication is division.

You take 3cm (the original shape's number) and divide it into 4.5cm. So 4.5cm divided by 3cm = 1.5. 1.5 fits in there,

therefore 20cm^2 times 1.5 = 30cm^2.

The answer for the third one would be 30cm^2. "30" in the blank.

(a) Loan you can afford is $143097.67. (b) Total money will you pay the loan company is $378000. (c) Interest amount is $234902.33.

Loan interest is the additional cost that a borrower must pay on top of the principal amount of a loan. Interest is typically expressed as a percentage of the principal and is charged over a specific period of time. The rate of interest charged on a loan is determined by a variety of factors, including the borrower's creditworthiness and the type of loan. The purpose of interest is to compensate the lender for the risk and cost of providing the loan.

Given data:

Principal = $1050 per month

Time = 30 year

        = 30 × 12

        = 360 months

Interest rate = 8%  

                    = 0.08/12

                    = 0.006667 monthly

(a) We get here first maximum amount of loan by present value of annuity as

Present value of annuity = principal ×  [tex]\frac{1-(1+rate)^{-t} }{rate}[/tex]           .........(1)

Put here value we get

value of annuity = 1050 × [tex]\frac{1-(1+0.006667)^{-360} }{0.006667}[/tex]

value of annuity = $143097.67

(b) Total amount  = principal × time period

                            = $1050 × 360

                            = $378000

(c) Total amount of interest paid will be

interest amount = total amount paid - loan amount

interest amount  = $378000 - $143097.67

The population of the state is 23.1 million

The population of the state will reach 28.3 million in 13.5 years

What is population ?

Any whole group that shares at least one trait is referred to be a population. People do not make up all populations. Populations can include, but are not limited to, individuals, animals, organizations, structures, buildings, cars, farms, objects, or occasions.

The population state is:

A = 23.1*e^(0.0153*t)

In millions.

Where t represents the number of years after 2000.

a) For the population at the year 2000, we need to evaluate the function at t = 0 (2000 is 0 years after 2000).

A(0) = 23.1*e^(0.0153*0) = 23.1

The population at year 2000 was 23.1 millions.

b) Now we want to solve:

A(t) = 28.3 = 23.1*e^(0.0153*t)

        28.3/23.1 = e^(0.0153*t)

        1.23 = e^(0.0153*t)

Now we can apply the natural logarithm to both sides:

ln(1.23) = ln( e^(0.0153*t) )

ln(1.23) = 0.0153*t

ln(1.23)/0.0153 = t = 13.5

So 13.5 years after 2000 the population will be 28.3 million.
