The product of two even numbers is even.

Let m and n be any integers so that 2a and 2b are two even numbers.

The product is 2a(2b) = 2(2ab), which is even.

Answer:

The tank can hold  4423.36 feet³ of water.

Step-by-step explanation:

Given that,

Height = 22 feet

Diameter = 16 feet

We need to calculate the maximum amount of water

Using formula of volume

[tex]V=\pi r^2h[/tex]

Where, h = height of cylinder

r = radius of cylinder

Put the value into the formula

[tex]V=\pi\times(8)^2\times 22[/tex]

[tex]V= 4423.36\ feet^3[/tex]

Hence, The tank can hold  4423.36 feet³ of water.

-2.3

Negative 2.ModifyingAbove 3 with bar

Step-by-step explanation:

-2.3 is the rational number among the given options.

A number system is defined as a system of writing to express numbers.

Rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.

Any decimal number can be either a rational number or an irrational number, depending upon the number of digits and repetition of the digits.

Any decimal number whose terms are terminating or non-terminating but repeating then it is a rational number

In the given decimal numbers 2.323232..., 2.32222... 2.323148... and -2.3.

The first three decimal numbers are irrational because it is not terminating and -2.3 is rational.

Hence, -2.3 is the rational number among the given options.

Answer:

Distance AB is 18.79 units

Step-by-step explanation:

Given two points with coordinates as:

A= (-4,7)

B= (-12, -10)

To find:

Distance AB = ?

Solution:

To find the distance between two points with given coordinates, we can use Distance formula.

Distance formula  is given as:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are the two coordinates whose distance is to be find out.

[tex]x_1 = -4\\y_1 = 7\\x_2 = -12\\y_2 = -10[/tex]

[tex]AB = \sqrt{(-12-(-4))^2+(-10-7)^2}\\\Rightarrow AB = \sqrt{(-8)^2+(-17)^2}\\\Rightarrow AB = \sqrt{64+289}\\\Rightarrow AB = \sqrt{353}\\\Rightarrow \bold{AB = 18.79\ units }[/tex]

Distance AB is 18.79 units

Answer:

AB = 18.8 units

Step-by-step explanation:

If there are two points (x1,y1) and (x2,y2) on the coordinate plane.

distance between those two points = [tex]\sqrt{(x1-x2)^{2} + (y1-y2)^{2} }[/tex]

given points are

A= (-4,7)

B= (-12, -10)

[tex]AB = \sqrt{(-4 -(-12))^{2} + (7-(-10))^{2} }\\AB = \sqrt{(-4 +12)^{2} + (7+10)^{2} }\\AB = \sqrt{(8)^{2} + (17)^{2} }\\AB = \sqrt{64 + 289 }\\AB = \sqrt{353 }\\AB = 18.79[/tex]

Thus, length of AB is 18.79 units

since, value of hudredth of unit is 9 which is greater than 9 then rounding the value to nearest tenth of unit we increase the value at tenth of unit place by that is 7 becomes 8

length of AB  to the nearest tenth of a unit is 18.9 units

Jan's age = [tex] 4\frac{5}{6}[/tex] years

Sister's age =[tex] 9\frac{2}{3} \: years[/tex]

Step-by-step explanation:

Jan's age = x years

Sister's age = 2x years

Brother's age = 3x years

According to the given condition:

x + 2x + 3x = 29

6x = 29

x = 29/6

x = [tex] 4\frac{5}{6}[/tex] years

2x = [tex] 2\times \frac{29}{6}= \frac{29}{3}=9\frac{2}{3} \: years[/tex]

This isn't an answer, rather a suggestion.

I would use the website desmos to help you out. But it won't help you forever like when you do quizzes or tests.

Directions:

Make the variable "y" all by itself. It need to be solo. For example for problem 34, negate 3 on each side and you will have "y=1/2(x+2)+3".

From there, plug in numbers into the x variable. (I suggest using common factors of "2" since the number your multiplying is 1/2.

Again using 34,

y=1/2(x+2)+3

y=1/2(2+2)+3

y=1/2(2+2)+3

y=1/2(4)+3

y=2+3

y=5

The coordinates are (2,5). Plot the coordinate.

Repeat the process.

Answer:

The amount invested at 7% is $12,000 while the amount invested at 10% is $8,000

Step-by-step explanation:

The given parameters are;

The total amount Hank invested = $20,000

The interest earned in one year = $1640

Hank invested part of the $20,000 at 7% interest and part of the $20,000 at 10%

Let the part invested at 7% = X and the part invested at 10% = Y, we have;

7% of X + 10% of Y = $1640 which gives;

0.07×X + 0.1×Y = $1640.....................(1)

X + Y = $20,000.................................(2)

Multiply equation (1) by 10 and subtract equation (1) from equation (2) to get;

X + Y - 10×(0.07×X + 0.1×Y) = $20,000 - 10×$1640

X - 0.7·X - Y - Y = $20,000 - $16,400 = $3,600

0.3·X = $3,600

X = $3,600/0.3 = $12,000

X = $12,000

Y = $20,000 - X = $20,000 - $12,000 = $8,000

Y = $8,000

Therefore, the amount invested at 7% = $12,000 and the amount invested at 10% = $8,000.

Answer:

$8,000 at 10%

$12,000 at 7%

Step-by-step explanation:

Let the part invested at 10% = x

Let the part invested at 7% = $20,000 - x

7% = 0.07

10% = 0.10

Hank invested a total of $20,000, part at 7%

0.07(20000 - x)

And part at 10%

0.10(x)

Hence, we have:

0.10x + 0.07(20000 - x) = 1640

0.10x + 1400 - 0.07x = 1640

0.10x - 0.07x = 1640 - 1400

0.03x = 240

x = 240/0.03

x = 8000

Hence, the amount he invested at 10% = $8,000

The amount he invested at 7% =

$20,000 - x

= $20,000 - $8,000

= $12,000

x > 5

x ∈ [ 5 ; + oo )

–6x + 15 < 10 – 5x

15 - 10 < 6x - 5x

5 < x

x > 5

x ∈ [ 5 ; + oo )

Answer: x>5

Step-by-step explanation:

Given

-6x+15<10-5x

Add 6x on both sides (Addition property of equality)

-6x+15+6x<10-5x+6x

15<10+x

Subtract 10 on both sides (Subtraction property of equality)

15-10<10+x-10

5<x

x>5

Answer:

(d/2)^2 pi

Step-by-step explanation:

To find the area of a circle the formula is A=pi times radius sqaured. Since we do not have the radius we need to find it. The radius will always be half the diameter hence the (d/2). This will give us the radius, next is just to complete the area formula by squaring the radius and multiplying it by pi.  i hope this helps :)

The circle's area, in function of it's diameter, is given by:

[tex]A = \frac{\pi d^2}{4}[/tex]

----------------------

[tex]A = \pi r^2[/tex]

[tex]A = \pi r^2[/tex]

[tex]A = \pi (\frac{d}{2})^2[/tex]

[tex]A = \pi \frac{d^2}{4}[/tex]

[tex]A = \frac{\pi d^2}{4}[/tex]

Which is the area of a circle of diameter d.

Answer:

740

Step-by-step explanation:

Let the AP be a, a+d, a+2d, a+3d, ...

The  term of AP is given by:

[tex]t n =a+(n-1)d[/tex]

We are given that the third term is 7.

[tex]t 3=7[/tex]

⇒  [tex]a+(3-1)d=7[/tex]

⇒[tex]a+2d=7 ---(1)[/tex]

Also, the seventh term is 2 more than three times the third term.

[tex]t7=3t3+2[/tex]

⇒[tex]a+ (7-1)d=3(a+(3-1)d)+2[/tex]

⇒[tex]a+6d=3(a+2d)+2[/tex]

⇒[tex]a+6d=3a+6d+2[/tex]

⇒[tex]-2a=2[/tex]

⇒[tex]a=-1[/tex]

We can put it in (1)

[tex]a+2d=7[/tex]

⇒[tex](-1)+2d=7[/tex]

⇒[tex]2d=8[/tex]

⇒d=4

Now, the Sum of n terms of an AP is given by the formula:

[tex]sn=\frac{n}{2}(2a+(n-1)d)[/tex]

So, Sum of first 20 terms would be:

[tex]s 20=\frac{20}{2}(2(-1) +(20-1) x 4)[/tex]

⇒[tex]s20=10(-2+19 x 4)[/tex]

⇒[tex]s 20=10 x(-2+76)[/tex]

⇒[tex]s 20= 10 x 74[/tex]

⇒[tex]s 20=740[/tex]

Thus, The Sum of first 20 terms of the AP is 740.
