Step-by-step explanation:

the inner and the outer angle at a vertex of a triangle are complementary angles or a linear pair of angles.

that means together they have 180°.

180 = inner + outer = 48 + outer

outer = 132°

the exterior angle is 132°.

Answer: B

Step-by-step explanation:

The width = 23/4

The length = 2 × the width = 2 × 23/4 = 23/2                

The perimeter of the rectangle = 2 ( length + width)

                                                    = 2 (23/2 + 23/4 )

                                                    = 2 ( 69/4)

                                                    = 69/2

What is shell?

A hard, protective outer layer is typically produced by an animal that lives in the sea and is referred to as a shell, seashell, or simply a shell. The animal's body includes the shell. Beachcombers regularly discover empty seashells washed up on beaches.

Given: Amit sold 3 shells last week for $5 each.

And 2 more shells this week for $5 each.

So, the equation which represent the total money is,

$5(3) + $5(2) = $15 + $10 = $25.

Also we can express this equation as,

$5(3 + 2) = $5(5) = $25

Therefore, the two ways to determine how much money Amit made in the two weeks are,

$5(3 + 2) = $25 and $5(3) + $5(2) = $25

The car's cost 3 years ago was $22,045.45.

According to the question,

We have the following information:

A new car costs $24,250, which is approximately 110% of what a comparable car cost 3 years ago.

Now, let's take the cost of car 3 years to be $x.

So, we have the following expression:

110% of x = 24250

110x/100 = 24250

Using the cross multiplication method:

110x = 24250*100

Dividing both sides by 110 will give us the value of x which is the required cost of car:

x = 2425000/110

x = $22045.45

Hence, the car's cost 3 years ago was $22,045.45.

Answer:

Step-by-step explanation:

t is given that a scuba driver descends in water for 2.8 minutes at a rate of   feet per minute.

Let's assume the descending position as negative.

The position at which the scuba driver will be after 2.8 minutes is :

= -  feet per minute × 2.8 minutes

= - 57.4 feet

Now , he sees a large fish and changes his direction and starts diving ascending at a rate of 25 feet per minute for 2 minutes.

Let's assume the ascending position as positive.

So , The position at which the scuba driver will be after 2 minutes after seeing large fish is :

= 25 × 2

= 50 feet

So , the scuba diver's position relative to sea level after the 4.8 minutes will be :

= -57.4 + 50

= -7.4 feet

This meant Scuba driver is 7.4 feet below sea level.

The price per pound of meat is $4.60.

Given that hamburger meat is priced at $5.98 for 1.3 pounds of meat.

It should be noted that to find the cost per pound of meat, we will need to divide the value given.

This will be:

= Cost of meat / Pound of meat

= $5.98 / 1.3

= $4.6

The point B and C are opposite to each other.

A number line is a mathematical visual representation of numbers on a straight line. The digits on a number line are positioned sequentially at regular intervals throughout its length. It frequently appears horizontally and might go on forever in any direction.

As seen from the number line, point A is one unit left of -1 which is -2. Since each mark is a difference of 1 and to the left is a negative value, point B is midway between -1 and 0 is half of -1 which is -0.5, point C is midway between 0 and 1 is basically half of 1 which is 0.5 and point D is halfway between 1 and 2 is exactly that 1.5

As per the numerical values of the given points, the two that are opposites to each other are points B and C. They both have a value of 0.5 on each end of the number line, one being negative while the other is positive, thus they are opposites of each other.

Point A is 1 mark to the left of negative 1. Point B is halfway between negative 1 and 0. Point C is halfway between 0 and 1. Point D is halfway between 1 and 2.

The equation of a line which is parallel to the given line; y = 6x - 2 as required in the task content is; Choice D-y = 6x + 3.

It follows from the task content that the equation of a line which is parallel to the given equation; y = 6x - 2 is to be determined.

First, by comparison the given equation with the slope-intercept model of a linear equation; y = mx + c. where m is slope and c is y-intercept.

Slope, m = 6.

Hence, since parallel lines are lines which have equal slopes.

The slope of the required line is therefore; 6 and it's y-intercept (0, 3) has a y-coordinate of; 3.

The required equation of the line is therefore; y = 6x + 3.

Answer: z=24/7

Step-by-step explanation:

The time at which the two bottles will have the same amount of water, using linear functions, is of:

26 seconds.

The slope-intercept representation of a linear function is given by the rule shown as follows:

y = mx + b

The coefficients of the function and their meaning are described as follows:

For the functions in this problem, we have that:

Hence the functions are given as follows:

The time at which they have the same amount is x for which:

P(x) = J(x)

65 - 2.5x = 20 - x

1.5x = 45

x = 45/1.5

x = 30 seconds.

However, at this time, the amount would be of:

J(30) = 20 - 30 = -10.

Which is a negative amount of water, not possible, hence they would have the same amount when Jason finishes, hence:

65 - 2.5x = 0

2.5x = 65

x = 65/2.5

x = 26 seconds.

The problem is:

He would pay $8500 interest if he can afford payments of $425 per month and can borrow the money at an interest rate of 4% compounded monthly for 5 years.

The expense of borrowing money is interest. It equates to a fee or additional charge the borrower pays the lender for the loaned amount, and is sometimes stated as a percentage. When you make a payment on a loan with simple interest, the money first goes toward the interest for that month and the rest is applied to the principal. Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.

Given,

Principal = $425

Rate = 4%

Time = 5 years

Interest = Principal × Rate × time

Interest:

= 425 × 4×5

= 8500

He would pay $8500 interest if he can afford payments of $425 per month and can borrow the money at an interest rate of 4% compounded monthly for 5 years.

Representation of 0 and 1 on The Number Line

So, the point represents (1-0)/2 = ½

Fraction - Representation Of Fraction On The Number Line

Thus we saw, to represent a fraction on the number line, we need to divide the line segment between two whole numbers into n equal parts where n represents the denominator of the fraction. For example, if we have to represent the fraction 1/5 on the number line, hence, we need to divide the line segment between 0 and 1 into five equal parts, where the first point as shown in the figure represents the fraction 1/5, the second represents 2/5 and so on.

We must note that, 0/5 = 0 here and 5/5 = 1.

30 weeks

Step-by-step explanation:

The given scenario can be modelled using the linear equation:

[tex]y=mx+b[/tex]

where:

Mindy initially owns 20 pairs of shoes. Therefore, the initial value is b = 20.

If Mindy purchases 2 pairs but destroys 1 pair each week, then she is gaining 1 pair of shoes each week.  Therefore, the rate of change is m = 1.

Therefore, the equation is:

[tex]y=x+20[/tex]

where:

To find how long it will take for Mindy's closet to have 50 pairs of shoes, substitute y = 50 into the equation and solve for x:

[tex]\implies 50=x+20[/tex]

[tex]\implies 50-20=x+20-20[/tex]

[tex]\implies 30=x[/tex]

i is expression is equivalent to i233.

Given i233

We know that i2 = -1 , if we square (i2) we get (-1)2 = 1

So, if i is multiplied to (i2), we get i3 = (-1).i = -i

Again if i is multiplied to i3 , we get i4 = (-i).i = -i2 = -(-1) = 1

Hence, all even powers of i after 2, will give answer as 1

The sequence will continue as a cycle as i, -1, -i, 1

So, i233 can be rewritten as i232 + 1= i232.i

i233 = (i2)116 .i = (-1)116 . i

Since the power 116 is even , the term becomes 1.i = i
