2.In △MTV, TPis an angle bisector. If m∠MTP=12 and m∠MTV=3x-3, find the value of x.

Answer:

I think the answers are the last two.

Step-by-step explanation:

A rational number is any faction with a denominator not being 0. For example, 1/2, 1/5, 3/6, etc. Also, the number 0 is also a rational number.

If you think any other ones are also the answer, just use my explanation to help it clear stuff up. :)

The better deal of the given pair is $31.05/1. The unit rate is $2.07.

The better deal is the deal that has the lower unit rate. Unit rate is the price per gallon. The unit rate can be determined by dividing the total cost by the total gallons bought.

Division is the operation that is used in mathematics to determine the quotient of two or more numbers. Division entails grouping a number into groups using another number. Other operations used in mathematics are addition, multiplication and subtraction.

Unit rate = total cost / number of gallons

$56 / 25 = $2.24

$31.05 / 15 = $2,07

The total cups of flour Alice, Raul and Jane have altogether is equal to 6.

We can determine the number of cups of flour they have all together by the addition of the fractions brought by each one of them.

First, we convert the decimal value of 2.5 into fraction form;

2.5 = 2.5/1

Multiplying and dividing both sides by 10;

25/10 = 5/2

Now we add the fractions as follows;

Total number of cups of flour = 5/2 + 11/4 + 3/4

We Multiply 5/2 by 2 to get the same denominator as the other values;

5×2 / 2×2 = 10/4

10/4 + 11/4 + 3/4 = 6

Therefore, the total number of cups of flour they have altogether is calculated to be 6.

It is not possible for the car to go over the speed limit as maximum error represent value of speed limit less than 65 miles per hour.

As given in the question,

Maximum error on the reading of speedometer =1.6%

Speed limit on a road is 65 miles per hour

Reading of a speedometer = 63 miles per hour

As per the error in the speedometer it can be more or less by 1.6%

To check speed limit

If it more

Speed limit  = 63 + (1.6% of 63)

                   = 63 + 1.008

                   = 64.008 miles per hour < 65 miles per hour

If it less

Speed limit = 63 - (1.6% of 63)

                   = 63 -1.008

                   = 61.992 miles per hour < 65 miles per hour

Therefore, it is not possible for the car to go over the speed limit as maximum error represent value of speed limit less than 65 miles per hour.

The complete question is:

The reading on a car speedometer has 1.6% maximum error the speed limit on a road is listed 65 miles per hour.

The car’s speedometer reads 63 miles per hour. Is it possible that this car is going over the speed limit?

When the scale on a map is 1 : 30000, the actual distance represented by 1 centimetre is 300 meters.

It should be noted that in order to get the distance, we have to convert 1cm to meter. It should be noted that;

100cm = 1 meter

1cm = 1/100 = 0.01 meters.

Therefore, when the scale on a map is 1 : 30000, the actual distance represented by 1 centimetre will be:

Answer:

-10x - 29 = -18x + 91

x = 15

Step-by-step explanation:

29 less than -10 times a number is equal to -18 times the number plus 91:

-10x - 29 = -18x + 91

add 21 to both sides:

-10x - 29 + 29 = -18x + 91 + 29

-10x  = -18x + 120

add 18x to both sides:

-10x + 18x  = -18x + 120 + 18x

8x = 120

divide both sides by 8:

8x/8 = 120/8

x = 15

Given: 2 |x + 3| +1 > 3 absolute value inequality.

We must solve and graph the following absolute value inequality:

2 |x + 3| +1 > 3

Take a look at the following absolute value inequality: 2 |x + 3| +1 > 3

We have to apply absolute rule:

If |u| > a , a > 0 then u < -a or u > a.

2|x + 3|+1 < -3 or 2|x + 3|+1  >3

Consider inequality first.

2|x + 3|+1 < -3

When we subtract 1 from both sides, we get,

2|x + 3| +1 -1 < -3 -1

Simplify,

2 |x + 3| < -4

We get by dividing both sides by two,

(2|x + 3|)/2 < -4/2

|x + 3| < -2

There is no solution for x ∈ R.

Now consider the second inequity.

2|x + 3|+1  >3

When we subtract 1 from both sides, we get,

2|x + 3|+1 - 1  >3 - 1

Simplify,

2|x + 3|  >2

We get by dividing both sides by two,

(2|x + 3|) / 2  >3/2

|x + 3| > 1

x + 3 < -1 or x + 3 >1

x < -4 or x > -2

As a result, we have the solution to the absolute value inequality:

2|x +3|+1  > 3 as

There is a 0.087 = 8.73% chance that four arrivals will occur at the same half-hour.

In which case,

x represents the number of successes.

The Euler number is e = 2.71828 = 2.72

μ is the average over the given time interval.

With a rate parameter of five per hour, the Poisson process is used.

So, μ = 5

The likelihood of exactly four arrivals occurring at the same time;

This is known as P(X = 4).

Put the values in the formula;

P(X = x) = (e∧(-μ)× μˣ) / x!

P(X = 4) = (2.72∧(-5)× 5⁴) / 4!

Simplifying the equation;

P(X = 4) = 0.08736

P(X = 4) = 8.73%

0.087 = 8.73% chance that exactly four arrivals happen during a specific half -hour.

The measure of the sides of rectangle is 14cm.

Each pair of neighboring sides in a rectangle are perpendicular, making it a special case of a parallelogram. A parallelogram is a specific type of trapezium, also referred to as a trapezoid in North America, in which the lengths of the two pairs of opposite sides are parallel. A quadrilateral with four right angles is a rectangle. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equal sides.

Given that,

One side of rectangle is 5cm than the other side.

Its perimeter is 38 cm.

P = 2b +2 h

38= 2b+ 2(5)

38= 2b+ 10

38-10= 2b

Step-by-step explanation:

because the rule says have u understand

Our function is a parabola, therefore, it has only one critical point which is its vertex. Since the coefficient of the squared term is negative, the vertex is the maximum point.The critical points of a function are given by the zeros of the first derivative. The first derivative of our function is:

The solutions for the following equation are the critical points of the original function:

The maximum point happens at x = - 3.

To find the corresponding value, we just have to evaluate x = - 3 into our function:

The maximum value of the function is 1, and it occurs at x = - 3.

Answer: The function has a maximum value

               The function's maximum value is 1

               The function's maximum value occurs at x=-3

Step-by-step explanation:

Given equation: [tex]g(x) = -3x^ - 18x - 26[/tex]

We shall use the differentiation method to find the answer.

Differentiating the equation, we get   [tex]g'(x) = - 6x - 18[/tex]

equating g'(x) = 0,

[tex]-6x - 18 = 0\\-6x = 18 \\x = -3[/tex]

Hence the minimum/ maximum value of the function lies in x = -3

on equating x>-3, g'(x) is negative

on equating x<-3, g'(x) is positive

this proves that first, the function was increasing and after x = -3, the function started to decrease hence at x=-3, the function g(x) was at its maximum value

The function's maximum value at x=-3 is

[tex]g(x) = -3x^2 - 18x - 26\\g(-3) = -3(-3)^2 - 18(-3) - 26\\g(-3) = -3(9) +54 -26\\g(-3) = 54 - 27 -26\\g(-3) = 1[/tex]
