What’s the distance between 120 and -50 on a number line ?
Answer:
170
Step-by-step explanation:
The distance between 120 and -50 on a number line is equal to 170.
What is a number line?In Mathematics and Euclidean Geometry, a number line is a type of graph that is composed of a graduated straight line, which typically comprises both negative and positive numerical values that are located at equal intervals along its length.
This ultimately implies that, every number line would primarily increase in numerical value towards the right from zero (0) and decrease in numerical value towards the left from zero (0).
Based on the information provided above, we would determine the distance between the two numerical values 120 and -50 by using the number line as follows:
x = 120 - (-50)
x = 120 + 50
x = 170.

A clothing company has 4 different kinds of sweatshirts. Each year, the company makes 60,000 of each kind of sweatshirt. How many sweatshirts does the company make each year?
Answer:
Step-by-step explanation:
Given that,
The company makes 4 different sweat shirts
Each year they make 60,000 of each kind.
So, if they will make 60,000 sweat shirt for each brand and the company design 4 different brand.
So, number of brand is 4
n = 4.
Then,
1 brand = 60,000
Therefore, 4 brand = 60,000 × 4
4brand = 240,000 sweat shirts.
So, in a year the company will make 240,000 sweat shirts.
The company makes a total of 240,000 sweatshirts each year by producing 60,000 of each of the 4 different kinds.
The question asks for the total number of sweatshirts produced by a company each year if it makes 60,000 of each kind and there are 4 different kinds of sweatshirts.
Identify the number of different kinds of sweatshirts: 4.Determine the number of each kind of sweatshirt made annually: 60,000.Multiply the number of kinds by the number of each kind: 4 x 60,000 = 240,000.Therefore, the company makes a total of 240,000 sweatshirts each year.

Answer:
If I remember correctly,
P x 9 = $60.75 and 6 x(times) $1.25=c
Step-by-step explanation:
First problem:
Since the total price of all 9 sandwiches is $60.75, that means that the price of one sandwich nine times will equal the total price.
Second problem:
Rather than giving you the total price, it gives you the price of one drink, so to find the total price you would need to multiply the price of one drink by the number of drinks to get the total (the total being c in this case)

roundyour answer to the nearest meter.
Answer:
84 meters.
Step-by-step explanation:
Set each tower equal to each other and you get (3.1/1.71)=(x/46.5)
Solve for X
X≈84.2982
But we want the nearest meter, so it's just 84 meters.
Answer:
84 meters
Step-by-step explanation:
The proportional value, or ratio is as the following:
[tex]\frac{3.1}{1.71} = \frac{x}{46.5}[/tex]
Now we can cross multiply in order to solve the equation...
[tex]1.71x=3.1*46.5\\1.71x = 144 \frac{3}{20}\\ x=84.3[/tex]

A circle of a certain radius has an area which is numerically 5 times the value of the circumference. What is the radius of the circle?
We have been given that a circle of a certain radius has an area which is numerically 5 times the value of the circumference. We are asked to find the radius of the circle.
We know that area of circle with a radius of r units is [tex]\pi r^2[/tex].
We know that circumference of a circle is [tex]2\pi r[/tex].
5 times the value of circumference would be [tex]5(2\pi r)=10\pi r[/tex].
Now we will equate 5 times circumference with area as:
[tex]\pi r^2 = 10\pi r[/tex]
Let us solve for r.
[tex]\pi r\cdot r = 10\pi r[/tex]
[tex]\frac{\pi r\cdot r}{\pi r}=\frac{10\pi r}{\pi r}[/tex]
[tex]r=10[/tex]
Therefore, the radius of the circle would be 10 units.
What are all the simplified form of the equation 3(4x - 2) = 9 + 2x + 5
Step-by-step explanation:
Step 1: Distribute
[tex]3(4x - 2) = 9 + 2x + 5[/tex]
[tex](3 * 4x) + (3 * -2) = 14 + 2x[/tex]
[tex]12x - 6 = 14 + 2x[/tex]
Step 2: Add 6 to both sides
[tex]12x - 6 + 6 = 14 + 6 + 2x[/tex]
[tex]12x = 20 + 2x[/tex]
Step 3: Subtract 2x from both sides
[tex]12x - 2x = 20 + 2x - 2x[/tex]
[tex]10x = 20[/tex]
Step 4: Divide both sides by 10
[tex]10x / 10 = 20 / 10[/tex]
[tex]x = 2[/tex]

since 2010 the town of fall river has been experiencing a growth in population according to the model what will the population of fall river be in 2020
Answer:
the population of fall river will be 48558
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Since 2010, the town of Fall River has been experiencing a growth in population. The relationship between the elapsed time, t, in years, since 2010 and the town's population, P(t left parenthesis, t, right parenthesis, is modeled by the following function. P(t)=36,800⋅[tex]2^{\frac{t}{25} }[/tex] According to the model, what will the population of Fall River be in 2020? Round your answer, if necessary, to the nearest whole number.
My answer:
Given the exponential function:
P(t)=36,800⋅[tex]2^{\frac{t}{25} }[/tex] where:
t in years, since 2010 the town's population, P(t)As we know, from 2010 to 2010 are 10 years
Hence, to find the population of fall river be in 2020, we substitute t =10 into the given function:
[tex]P(10)=36800\cdot2^{^\dfrac{10}{25}}}\\=48557.9\\\approx 48558[/tex]
So in 2020, the population of fall river will be 48558
Hope it will find you well.
Answer:
By 2020 the population of Fall River will be 48558
Step-by-step explanation:
Here, we note that the equation for the model is p(t) = 36,800×2^(t/25)
That is the format;
[tex]p(t) = 36,800 \times 2^{\frac{t}{25}[/tex]
Where:
t = Number of years since 2010
Therefore, the population of the town in 2020 can be found by first finding the number of years between 220 and 2010 and plugging the value into the equation as follows;
Number of years, t = 2020 - 2010 = 10 years
Hence;
[tex]p(t) = 36,800 \times 2^{\frac{10}{25}} = 48557.89 \approx 48558[/tex]
Therefore, according to the model, by 2020 the population of Fall River will be 48558.
A pack of 6 cans of pop costs £1.80. A pack of 10 cans of pop costs £3.50.
Which one should you buy?
Let us look at the cost per can of both packs.
Cost of can in 6-pack = 1.80/6
= £0.30
Cost of can in 10-pack = 3.50/10
= £0.35
Since the cost of a can in the 6-pack is cheaper, it would be better to buy the 6-pack if you were looking to save money.

Line d has a slope of –7 4 . Line e is perpendicular to d . What is the slope of line e ? Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Final answer:
The slope of line e, which is perpendicular to line d with a slope of -7/4, is 4/7.
Explanation:
The slope of line d is -7/4. To find the slope of a line perpendicular to d, we use the property that the product of the slopes of two perpendicular lines is -1. So, the slope of line e is the negative reciprocal of -7/4.
To find the negative reciprocal, we find the reciprocal by flipping the fraction and then negate it by changing the sign. Therefore, the slope of line e is 4/7.
