Answer:

perimeter of a square =side side

Answer:

64

........................

Answer:

20

The denominators of 3 /10  and  1 /4  are 10  and  4.

The factors of  10  are  2 × 5  and  2 × 2

Therfore the LCD should have two 2's and one 5.

This means the answer is:

2 × 2 × 5 = 20

I hope this helps :)

a) c + y = 10 + 11 = 21

b) q + b + r = -14 + (-7) + (-13) =

= -(14 + 7 + 13) = -34

c) 8x + 3z = 8 · 9 + 3 · 4 = 72 + 12 = 84

d) 6a + 5b = 6 · (-1) + 5 · (-3) = -6 - 15 = -21

e) -9y + 2z = -9 · (-5) + 2 · (-7) = 45 - 14 = 31

f) -3t + 4y + s = -3 · 8 + 4 · (-2) + (-2) =

= -24 - 8 - 2 = -(24 + 8 + 2) = -34

g) y² + c = 4² + 7 = 4 · 4 + 7 = 16 + 7 = 23

h) a² + x = (-10)² + (-8) = 100 - 8 = 92

i) b + 2y² = 2 + 2 · 6² = 2 + 2 · 36 =

= 2 + 72 = 74

j) 3y² - 3z = 3 · 6² - 3 · (-7) = 3 · 36 + 21 =

= 108 + 21 = 129

Answer:

(6, 8 )

Step-by-step explanation:

Assuming the dilatation is centred at the origin, then multiply the coordinates by the scale factor 2, that is

(3, 4 ) → (2(3) , 2(4) ) → (6, 8 )

AB = AD [Given]

BC = CD [Given]

AC = AC [Same line segment]

So, ΔABC ≅ ΔADC [By SSS congruence criteria]

So, ∠ABC = ∠ADC [CPCT (Corresponding parts of congruent triangles)]

Hence, proved.

Answer:

I hope it will help U.

Answer:

See below.

Step-by-step explanation:

There are 2 options in finding the difference between f and 35, as you did not state in the question which if the 2 is the larger number.

(f-35)-5=f-35-5

=f-40

OR

(35-f)-5=35-f-5

=30-f

5 less than the difference of a number f and 35 is f - 40

The expression can be represented mathematically as follows:

Answer:

Students:Adults = 118:94

Step-by-step explanation:

212-118=94

The area of a square with sides of length 9 is 81 square units.

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

The space enclosed by the boundary of a plane figure is called its area.

The area of a figure is the number of unit squares that cover the surface of a closed figure.

Given that, a square with side length of 9 units, we need to find its area, We know that, the area of a square is given by the square of it side, so Area = side²

Area of the given square = 9²

= 9 x 9

= 81 sq. units

Hence. the area of a square with sides of length 9 is 81 square units.

[tex] \frac{16}{3} [/tex]

Step-by-step explanation:

➡️ [tex] \frac{ \frac{4}{3} }{ \frac{1}{4} } [/tex]

Dropping the object from a height is an illustration of an object in free fall. The object should be dropped at 2304 feet above the sea level.

Given that:

[tex]t = \frac 14 \sqrt h[/tex]

The height is calculated as follows:

[tex]t = \frac 14 \sqrt h[/tex]

Multiply both sides by 4

[tex]4t = \sqrt h[/tex]

Square both sides

[tex]16t^2 = h[/tex]

Rewrite as:

[tex]h = 16t^2[/tex]

The object reaches the ground in 12 seconds.

So: [tex]t = 12[/tex]

This gives:

[tex]h = 16 \times 12^2[/tex]

[tex]h = 2304[/tex]

Hence, the object should be dropped at 2304 feet above the sea level.

Answer:

Im pretty sure it's (-4,-1)

Answer:

Step-by-step explanation:

False

First you have to  know what a natural number is.

They are all the integers from 1 to infinity.

Naturally they are closed for addition. 3 + 9 = 12. You can make as many examples as you like. You will not get anything outside the natural numbers.

3934859433993393390 + 4 + 22 is still going to give you a natural number.

Subtraction is a different matter.

44 - 100 is not in the natural number system.

Multiplication is OK.

5555 * 44444 still is a member of the natural numbers.

What about division? Remember, all you need is one example that doesn't work to say that the natural numbers aren't closed. Ready. How about

Answer:

9

Step-by-step explanation:

let a = 2

b = 5

2a + b

Substituting the values,

=> 2(2) + 5

=> 4 + 5

=> 9

Let us consider that a = 2 ; b = 5

So, 2a + b

Substitute,

2a + b

→ 2×2 + 5

→ 4 + 5

Answer:

$94

Step-by-step explanation:

To find out how much she has after 5 weeks we need to use how much she has at 1 week. We know she starts the month with $54 and adds $8 at the end of a week. Knowing this we can multiply her amount for 1 week by 5 weeks (8x5), this gets us to $40, but since she started the week with 54 we need to add that to her 5 week's total (54+40), so we get a total of $94 after 5 weeks.

The total amount in Johanna's account after 5 weeks will be $94 if Johanna starts the month with $54 in her savings account at the end of each week, Johanna adds $8 to the account.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Johanna starts the month with $54 in her savings account.

At the end of each week, Johanna adds $8 to the account.

Let x be the total amount in Johanna's account after 5 weeks.

The linear equation in one variable can be framed as:

x = 54 + 8×5

x = 54 + 40

x = $94

Thus, the total amount in Johanna's account after 5 weeks will be $94 if Johanna starts the month with $54 in her savings account at the end of each week, Johanna adds $8 to the account.
