V=π(4^2)(19)

V=955.04

Lateral S.A.

S.A.=2πrh

Total S.A.

S.A.=2πrh+2πr^2

S.A.=2π(4)(19)+2π(4^2)

S.A.=578.05

Answer:

B.Yes,the adjacent sides are perpendicular,and the opposite sides are parallel

Answer:

B. Yes, the opposite sides are perpedicular, and the opposite sides are parallel

Step-by-step explanation:

This is because for a rectangle to be a rectangle, it has to have four sides whose opposite sides are equal (so parallel) and adjacent sides meets at 90° (so perpendicular), both of which this shape is shown to be.

The feasible region which is shown is the graph of is of the solution of  inequalities y<4,x>=0,x<4 and y>=1. which is option C.

An inequality is like an equation but is expressed in greater than ,less than, greater than or equal to, less than or equal to signs. It is equated to find the range of variables.

The given graph has three lines showing different inequality.

One which is parallel to x axis and present at y=4 is doted and because the region from this line is towards origin so the sign between y and 4 is of < sign and we don't use equal to sign as it is doted. The inequality will be y<4

Other line is also parallel to x axis at y=1 but it is not doted and the region shaded is away from the line and origin so we use > than sign and equal to sign. The inequality will be y>-1.

The solution lies in first quadrant so x>=0.

One line is parallel to y-axis at x=4 and because the solution is towards origin so we will use <=0 sign as it is not dotted also.

Hence the inequalities are y<4,x>=0<x<4, y>1.

Step-by-step explanation:

Answer:

[tex]\boxed{\sf{20x-45}}[/tex]

Step-by-step explanation:

To solve this problem, all you have to do is isolate the x from one side of the equation.

First, you have to combine like terms.

→ -5x+25x-15-30

Then, you subtract the numbers from left to right.

→ -15-30=-45

Rewrite the problem down.

→ -5x+25x-45

By similar, add to elements.

→ -5x+25x=20x

Rewrite the problem down.

⇒ 20x-45

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

20x - 45

Step-by-step explanation:

Start by grouping like terms ( -5x and 25x) , ( -15 and -30):

= -5x + 25x - 15 - 30

Subtract the numbers: -15 -30 = -45

= -5x + 25x - 45

Combine like terms ( 5x and 25x):

= 20x - 45

The ratio of juniors to seniors at 2:00 p.m. in fractional form is 43 / 37

Ratio is a term that is used to compare two or more numbers.

Therefore,

At 12 pm(noon) there are 700 juniors and 1100 seniors at the college fair. After 12:00 pm 20 juniors arrive every 15 minutes and 45 seniors leave every 15 minutes. Therefore,

The Junior population at 2:00 pm is as follows;

Then, 120 / 15 = 8

20 × 8 = 160 students

The junior student increased by 120 by 2pm.

The Senior population at 2:00 pm is as follows;

45 × 8 = 360 students

360 senior student left by 2 pm.

Therefore,

Junior student by 2pm = 700 + 160 = 860 students

Senior student by 2 pm  = 110 - 360 = 740 students

The ratio of juniors to seniors at 2:00 p.m. in fraction form is 860 / 740 = 43 / 37

Answer:

Step-by-step explanation:

You should always multiply before adding or subtracting. By saying "a product of 8 and 3," it means we multiplied them together first.

You should then add and subtract in the order in which they appear. Saying "five more" before "minus 2" means we did it in the right order.

Step-by-step explanation:

substitute the values of x from the table into the rule and evaluate for y

x = 4 → y = 5 + 4(4) = 5 + 16 = 21

x = 5 → y = 5 + 4(5) = 5 + 20 = 25

x = 8 → y = 5 + 4(8) = 5 + 32 = 37

x = 10 → y = 5 + 4(10) = 5 + 40 = 45

Step-by-step explanation:

Use the pythagorean theorem to solve for missing sides in a right triangle.

20²+48²= missing side

20²+48²=2704

Take the square root of 2704 to get the missing side.

[tex] \sqrt{2704 } = 52[/tex]

Answer :

⠀

Explanation :

⠀

Solution :

We'll solve this using the Pythagorean Theorem.

where,

⠀

We know that,

[tex]{\longrightarrow \bf \qquad (AC) {}^{2} = (AB) {}^{2} +( BC) {}^{2} } \\ \\ [/tex]

Now, we will substitute the given values in the formula :

[tex]{\longrightarrow \sf \qquad (AC) {}^{2} = (20) {}^{2} +( 48) {}^{2} } \\ \\ [/tex]

We know that, (20)² = 400 and (48)² = 2304. So,

[tex]{\longrightarrow \sf \qquad (AC) {}^{2} = 400 + 2304 } \\ \\ [/tex]

Now, adding 400 and 2304 we get :

[tex]{\longrightarrow \sf \qquad (AC) {}^{2} = 2704 } \\ \\ [/tex]

Now, we'll take the square root of both sides to remove the square from AC :

[tex]{\longrightarrow \sf \qquad \sqrt{ (AC) {}^{2}} = \sqrt{2704} } \\ \\ [/tex]

When we take the square root of (AC)² , it becomes AC,

[tex]{\longrightarrow \sf \qquad AC = \sqrt{2704} } \\ \\ [/tex]

We know that, square root of 2704 is 52 .

The Slope of line:

1. -5/2

2. 3

3. 0

4. -1

5. 7/3

6. ∞

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

1. Slope of line

= (1-11)/ (-2 +6)

= -10 / 4

= -5/2

2. Slope of line

= (-2+ 5)/ (-3+ 4)

= 3 / 1

= 3

3. slope of line

= (6-6)/ (3+1)

= 0

4. Slope of line

= (7-8)/ (2-1)

= -1

5. Slope of line

= (-1+8)/ (0+3)

= 7/3

6. Slope of line

= (3-5)/ (-2+ 2)
