Answer:

4

Step-by-step explanation:

when you write them down and draw a diaganal line from 7,2 to 5,5 it passes 4 intersections, so it would be 4 units. When you round if it is 4 or less it stays the same and if it is 5 or more then it changes so it would still be 4.

Answer:

135.09 kg

Step-by-step explanation:

First, we must determine the total weight of each bicycle including their boxes.  To do this, we must add 3.41 kg and 11.6 kg.  3.41 + 11.6 = 15.01.

Next, multiply the weight of one bike and its box to the total amount of bicycles there are.  There are 9 bikes, so 15.01*9 = 135.09 kg.

To find the total mass of all bicycles and their boxes, add the mass of one bicycle (11.6 kg) and its box (3.41 kg) to get the total mass for one unit (15.01 kg), and then multiply by the total number of bicycles (9), resulting in a total mass of 135.09 kg.

The total mass of all the bicycles and their packing boxes can be calculated by first determining the mass of one bicycle with its box, and then multiplying that by the total number of bicycles being shipped. The mass of one bicycle is 11.6 kg and the mass of its packing box is 3.41 kg. Adding these together gives us the total mass for one bicycle and its box.

Mass of one bicycle: 11.6 kg
Mass of one box: 3.41 kg
Total mass for one bicycle and its box: 11.6 kg + 3.41 kg = 15.01 kg

This total mass for one bicycle and its box must then be multiplied by the number of bicycles to obtain the total mass for all bicycles and their boxes.

Number of bicycles: 9
Total mass for all bicycles and boxes: 9 * 15.01 kg = 135.09 kg

Therefore, the total mass of all the bicycles and their packing boxes is 135.09 kg.

Answer: 30

Step-by-step explanation:5(Z+4) + 5(2-Z).

Open the brackets by multiplying true by the number out of the bracket.

5Z + 20 + 10 - 5Z

Now, collect like terms, we have.

5Z - 5Z + 20 + 10. Now we have

0 + 30 = 30//

The sum of the 5 terms in the arithmetic series is 40.

Step-by-step explanation:

Step 1;  First we need to determine the three values between a1= -14 and a5=30. The difference between the first and fifth value = 30 - (-14) = 30 + 14 = 44.

Since there are 4 values after a1 we divide the difference by the number of terms, the difference between each term = 44 / 4 = 11. So the difference between each term is 11.

Step 2; To find out the terms we just add the difference to the previous number.

a1 = -14.

a2 = -14 + 11 = -3.

a3 = -3 + 11 = 8.

a4 = 8 + 11 = 19.

a5 = 19 + 11 = 30.

So a1 + a2 + a3 + a4 + a5 = -14 -3 + 8 + 19 + 30 = 40.

The sum of the first 5 terms in this arithmetic series is 40, calculated based on the formulas for an arithmetic series involving the first term, the fifth term, and the common difference.

In an arithmetic sequence or series, the difference between each term (the common difference) is constant. We can represent this as: an = a1 + (n - 1) * d, where d is the common difference. Given in this problem that a1 = -14, a5 = 30, and n = 5.

First, we can find the common difference d using the formula: d = (a5 - a1) / (5 - 1) . So, d = (30 - (-14)) / (5 - 1) = 44 / 4 = 11.

Then, we can find the sum of the first 5 terms using the formula: Sn = n / 2 * (2a1 + (n - 1) * d). That gives us: S5 = 5 / 2 * (2(-14) + (5 - 1) * 11) = 5 / 2 * (-28 + 44) = 5 / 2 * 16 = 40.

It should take the student 1.75 minutes to complete 35 multiplication facts.

To determine how long it will take the 5th grade student to complete 35 multiplication facts at the same rate as 20 facts in 1 minute, we can set up a proportion or use unit rates. Since the student can complete 20 facts in 1 minute, we find the time per fact by dividing the total time by the number of facts:

1 minute / 20 facts = 0.05 minutes per fact

Then, we multiply the rate by the number of new facts:

0.05 minutes per fact * 35 facts = 1.75 minutes

Therefore, it should take the student 1.75 minutes to complete 35 multiplication facts.

Final answer:

Three rational numbers between 3 and 3.9 are 3.2, 3.3, and 3.6.

Explanation:

To list 3 rational numbers between 3 and 3.9, we can consider the numbers that lie between these two values.

We can start by looking for numbers with a tenths place greater than 3 but less than 9.

To find three rational numbers between 3 and 3.9, we simply need to choose numbers that have a finite number of digits after the decimal point.

Some examples of rational numbers in this range are 3.2, 3.3, and 3.6.

These satisfy the condition of being between 3 and 3.9.

7% of 50 is 3.5.

If you add 3.5 four times you'll get 14.

200 - 7% is 186.

200 - 14 is 186.

Answer:

$14

Step-by-step explanation:

Well, first find 7% of 50.  To do this you need to make the percent a decimal by moving the decimal that is already(7 is the whole number, if there were any fractions it would be 7.00%) there two space to the left, adding zeros as needed.  

0.07 x 50 = x

3.5 = x

Now you can multiply it by whatever you want.  In this case it would be 4 since 50 time 4 is 200.

3.5 x 4 = 14

So the amount of money that you would make would be $14.

Step-by-step explanation:

15 out of the 20 books are horses. 5 of those are nature. 5/20 is the fraction, but can be simplified to 1/4

Shira has 5 out of 20 books about nature on her bookshelf, which simplifies to a fraction of 1/4 of her books being about nature.

Shira has 20 books in total on her bookshelf. Out of these, she has 15 books about horses, meaning the remaining books are about nature.

To find the fraction that represents the nature books, we need to subtract the number of horse books from the total number of books.

So, the number of nature books is 20 total books - 15 horse books = 5 nature books. The fraction of books about nature would therefore be the number of nature books divided by the total number of books, which is 5/20.

This fraction can be simplified by dividing both the numerator and the denominator by 5, resulting in 1/4. Therefore, 1/4 of Shira's books are about nature.

Final answer:

To find the flooded area after 6 minutes, calculate the number of 1/5-minute intervals in 6 minutes, which is 30. Then, multiply by the area flooded in each interval. The flooded area after 6 minutes would be 1500 square feet.

Explanation:

The question is asking to calculate the area that would be flooded by a water pipe after 6 minutes, given that the pipe floods 50 square feet every 1/5 of a minute. To find the answer, we need to determine how many 1/5-minute intervals are in 6 minutes, and then multiply that number by the area flooded in each interval.

First, calculate the number of intervals: 6 minutes × (5 intervals/minute) = 30 intervals.

Next, multiply the number of intervals by the area flooded per interval: 30 intervals × 50 square feet/interval = 1500 square feet.

Therefore, after 6 minutes, the flooded area would be 1500 square feet.

I think it is obtuse and scalene, but I don't think that is the only answer. Hope that can help a little.

The triangle is an isosceles and an obtuse triangle.

A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.

In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle

The three types of Isosceles Triangles are :

Isosceles acute triangle

Isosceles right triangle

Isosceles obtuse triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of ∠ABC = 120°

So , it is an obtuse triangle with angle > 90°

Now , the measure of sides AB = measure of BC

So , an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base

Therefore , it is an Isosceles obtuse triangle

Hence , the triangle is isosceles

a. It spends 2.04 hours going 55 mph.

b. It will spend 1 hour going 35 mph.

c. The trip will take 3.64 hours.

Step-by-step explanation:

Given equation is;

55x + 35y = 200

Where

x represent the time when speed is 55 mph

y represent the time when speed is 35 mph

a. If the car spends 2.5 hours going 35mph on the trip, how long does it spend going 55mph?

Putting y=2.5 in given equation

[tex]55x+35(2.5)=200\\55x+87.5=200\\55x=200-87.5\\55x=112.5\\[/tex]

Dividing both sides by 55

[tex]\frac{55x}{55}=\frac{112.5}{55}\\x=2.04\ hours[/tex]

It spends 2.04 hours going 55 mph.

b. If the car spends 3 hours going 55mph on the trip, how long does it spend going 35mph?

Putting x=3 in given equation

[tex]55(3)+35y=200\\165+35y=200\\35y=200-165\\35y=35[/tex]

Dividing both sides by 35

[tex]\frac{35y}{35}=\frac{35}{35}\\y=1[/tex]

It will spend 1 hour going 35 mph.

c. If the car spends no time going 35mph, how long would the trip take?

Putting y=0 in given equation

[tex]55x+35(0) = 200 \\55x+0=200\\55x=200[/tex]

Dividing both sides by 55

[tex]\frac{55x}{55}=\frac{200}{55}\\x=3.636[/tex]

Rounding off

x = 3.64

The trip will take 3.64 hours

Answer:

The length of the side of the triangles are;

First side = 38 ft

Second side = 19 ft

Third side =24 ft

Step-by-step explanation:

To solve the question we are going to take;

Second side is x ft

Since, the first side is 2 times the second side then;

First side of the triangle is 2x ft

Since the third side is 5 ft less than the second side, then;

The third side is (x+5) ft

But, the perimeter of the triangle is 81 ft

Perimeter of a triangle is given by the sum of sides;

Therefore;

x + 2x +(x +5) = 81 ft

4x + 5 = 81

4x = 76

    x = 19 ft

Therefore;

Second side = 19 ft

First side = 38 ft

Third side = 24 ft
