Answer:

9 miles

Step-by-step explanation:

90 min = 1hr and 30 min

6(miles)*1(hr) = 6

6(miles)*0.5(hr) = 3

[ remember we multiply by 0.5 because half of 1 hour is 30 min. ]

Answer: 9 miles

Step-by-step explanation:

convert 90 minutes into hours: 90 mins/60 mins in an hour = 1.5 hours

find how far the team ran: 6mph * 1.5 hours = 9 miles

answer: the team ran 9 miles in 90 minutes

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 price is $4.60.

Step-by-step explanation:

Jasmine was not right in evaluating the expression. She didn't multiply the subtraction signs.

An algebraic expression consists of unknown variables, numbers and arithmetic operators.

To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number.

Therefore, let's evaluate Jasmine expression.

10 - (-3)

we have to open the bracket by multiplying the negative signs.

- × -  = +

Hence,

10 - (-3)  = 10 + 3 = 13

Therefore, Jasmine is wrong. Her mistake was not multiplying the minus sign.

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.

Therefore, points B and C are opposite to each other.

Step-by-step explanation:

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:

y = x + 20

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]

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

Therefore, it will take Mindy 30 weeks to have 50 pairs of shoes in her closet.

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

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:

Answer:

Step-by-step explanation:

We already know how to represent whole numbers on the number line. Let us consider the image shown, here, the digits 0 and 1 are represented on the number line.

Representation of 0 and 1 on The Number Line

If we divide the number line into two equal parts, as shown in the figure below, what value does that mid-point hold? Half of what the graduation between 0 and 1 holds.

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.

Fraction Representation

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

Here you have seen the representation of proper fraction on the number line. To represent improper fractions, you first convert them into mixed fractions. The same procedure, as shown above, is used with the whole number as the starting point.
