-3a-2b for a=-4 and b=-3

Answer:

Consider a class in which there are 40 students .There is a Mathematics test of 50 marks .Two students were absent.The Duration of test was for one and half an hour.

So Marks of students according to their roll number are 12,8,4,20,25,36,2,29,35,39,5,48,43,37,38,29,17,15,15,25,31,32,26,28,27,24,2,15,34,,50,46,48,37,28,26,45,49,24.

So in this case it would be better to prepare frequency polygon by selecting a class interval.

Class interval = 0-5,5-10,10-15,15-20,20-25,25-30,30-35,35-40,40-45,45-50.

Or 0-10,10-20,20-30,30-40,40-50.

or you can make class interval by yourself.

Let the radius of the base be r units

Then the height will be 3r units

Volume of cylinder = pi r^2 h

24=pi r^2 × 3r

Pir^3 = 24/3

Pi r ^3 =8

r^3 = 8/pi

R = 2 / pi^1/3

Height = 6/pi^1/3

About 1.3 pouds per day

To find this answer, you divide 29.99 by 40 and get 0.74975, which you round off to $0.75 for this question, hope it helped! <3

The distance between the points (−3, 5) and (−3, −6) is 11 units.

Distance between two points is the length of the line segment that connects the two given points.

Given are two points, (−3, 5) and (−3, −6)

We know, distance between two points are

= √(x2-x1)²+(y2-y1)²

= √(-3+3)² + (-6-5)²

= √121 = 11

Hence, The distance between the points (−3, 5) and (−3, −6) is 11 units.

The answer is 169.5 because you multiply

Answer:

Not a right triangle.  See below for my reasoning.

Step-by-step explanation:

If this is a right triangle, then the sum of the squares of the two shorter sides will equal the square of the longest side:  7^2 + 9^2 = 11^2 => 49 + 81 = 121   But this is false.

Answer:

It's not a right triangle, because already 7^2 = 7x7 which is 49 so...

Answer: 2282

Step-by-step explanation:

To get the answer, first we make an equation.

Lets use f for faults.

So we know that Patrick was born with 326 faults. He had 1/7 the number of faults he has now when he was born. The question is asking how many faults he has in total. Now we can set up our equation.

326 = 1/7f

326 is on the left of the equal sign because 326 is equal to 1/7 the number of faults he has now. Next, because 1/7 is 1 divided by 7, we multiply 1/7f by 7. We get 1f or f because there is only 1 f. But what we do to one side we must do to the other. So when we multiply 7 to 1/7f we also multiply 7 to 326. This is our answer:

2282 = f

Hey there!

Let's start by simply finding 1% of $400,000.

To do this we can divide by 100, since 1% is the same thing as 1/100.

400,000 ÷ 100 = 4,000

Next, we can multiply 4,000 by 15, because 4,000 is 1% and we are looking for 15%.

4,000 x 15 = 60,000

This means the tax is $60,000.

Hope this helps!

Final answer:

To solve for velocity v in the provided equation U=tsv, divide both sides by ts to isolate v, resulting in v = U / (ts).

Explanation:

Solving for v in Terms of s, t, and u:

To solve for v in terms of s, t, and u given the equation U=tsv, we can rearrange the equation to isolate v. We start by dividing both sides of the equation by ts, which results in:

v = U / (ts)

This equation shows that the velocity v can be calculated if we know the initial velocity u, the time t, and the displacement s.

       d < 6

Graph: ←----------------o 6

Answer:

option (c) is correct.

d < 6

On number line this is shown as attached below.

Step-by-step explanation:

Given inequality 4d - 6 < 18

We have to plot the inequality and check out of given graph which graph satisfies the Given inequality 4d - 6 < 18

Consider the given inequality 4d - 6 < 18

Add 6 both sides, we have,

4d - 6 + 6 < 18 + 6

Simplify we get,

4d < 24

Now, divide both side by 4, we have,

[tex]\frac{4d}{4}<\frac{24}{4}[/tex]

Simplify , we have,

d < 6

On number line this is shown as attached below.

Answer:

y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

Step-by-step explanation:

Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.

Let flat rental fee be c and cost per mile driven = m and miles driven = x

Total cost =y

Then y = mx+C is the linear equation.

to find m and c, we use the fact that y =110.30 when x = 222

i.e. 110.30 = c+222x

and similarly 99.05 = c+147x

Subtract to eliminate c

11.25 = 75 x

0.15 =x

Substitute in I equation

110.30 = c+222(0.15)

c = 77

y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

Answer:

y=0.15x + 77.00

Final answer:

To find the hikers' average speed, we use the difference in distance and time between two groups, yielding an average speed of 3.3 miles per hour.

Explanation:

To solve the problem of how fast the hikers are going, we need to calculate the average speed using the distance covered by Sally's group and the time difference between the two groups. The formula for average speed is Average speed = Total distance ÷ Total time.

Let's denote the average speed as v, the distance covered by Marks' group as d (which is the same as Sally's since they start at the same point and hike at the same speed but for different periods), and their respective times as t1 for Marks' group and t2 for Sally's group.

Given:

Sally's group covers 7.7 miles more than Mark's group

t1 = 2.5 hours and t2 = 4.7 hours

Equation: Since they have the same speed, Mark's distance d plus 7.7 miles equals the speed v multiplied by t2 (Sally's hiking time). So, d + 7.7 = v × t2. Also, because speed is constant, v = d ÷ t1. Combining these, we get v = 7.7 ÷ (t2 - t1).

Solution: Substitute the given values into the formula, v = 7.7 ÷ (4.7 - 2.5)

Answer: v = 3.3 miles per hour.
