A 25
foot long board is cut into two parts. The longer part is one foot more than twice the shorter part. How long is each part?

Answer: 25%

Step-by-step explanation: So, I think we know it's 50% chance to get heads or tails. But what's the chance of getting heads two times in a row....let's see...

[tex]\frac{1}{2} * \frac{1}{2} = \frac{1}{4}[/tex]

Let's turn [tex]\frac{1}{4}[/tex] into a decimal...

1 ÷ 4 = 0.25

0.25 * 100 = 25

= 25%

Thus, you have a 25% to get heads two times in a row...I hope this helps!

Answer:

Step 1: 1,000, Step 2: 1,000, Step 3: 30,000

Step-by-step explanation:

For the first step all you have to do is find out what times 5 is equal to 5000.

[tex]5*x=5000\\[/tex]

Then for the second one all you have to do is keep the same 1000, because:

[tex](5*6)*1000=30*1000[/tex]

It's the same thing.

Afterwards you can just assume that you'll have 30000 as your answer because multiply 30 by 1000 will give, 30 thousands.

[tex]30*100=30000[/tex]

Answer:

B. (-9/2, -11/2)

Step-by-step explanation:

-12+3 / 2 = -9/2

-3+-8 / 2 = -11/2

Answer:

20

Step-by-step explanation:

Because this is a right triangle, you can use the Pythagorean Theorem, a^2 + b^2 = c^2.  a and b are your legs and c is your hypotenuse, so you have 21^2 + b^2 = 29^2. This equals to 441 + b^2 = 841. subtract 441 from both sides and you are left with b^2 = 400. take the square root of both sides to get your answer b = 20, or x = 20.

Answer:

x = 20

Step-by-step explanation:

→You can use the Pythagorean Theorem to solve this:

[tex]a^2 +b^2=c^2[/tex]

→The "a," and "b," are the legs, 21 and x, while the "c," is the hypotenuse, 29. In this case, we are trying to find the value of a leg:

[tex]21^2+b^2=29^2[/tex]

[tex]441+b^2=841[/tex]

→Subtract 441 from both sides:

[tex]b^2=400[/tex]

→To get "b," by itself, you must take the square root of both sides, like so:

[tex]\sqrt{b^2} =\sqrt{400}[/tex]

[tex]b = 20[/tex]

Answer:

The second option you listed: x + y = 4 gives the same line as H, and therefore renders infinite number of solutions (as many as every point on the line)

Step-by-step explanation:

We need to look for the equation that exactly matches the given one :

2 x + 2 y = 8

notice dividing both sides of this equation by "2" we get:

x + y = 4

SO this equation represents exactly the same line as 2 x + 2 y = 8 does, and therefore their graphs overlap completely

The answer is 117 inches^3

Please see the attached picture for full solution

Answer:

Option C is correct

Step-by-step explanation:

Given: inequality is [tex]50-3.50x>100-6x[/tex]

To find: situation that can be represented by the given inequality

Solution:

Cost of Dunkin Donuts gift card with Daniel = $50

Amount spent by Daniel per day = $3.50

Cost of Dunkin Donuts gift card with David = $100

Amount spent by David per day = $6

Amount left with Daniel after x days = [tex]\$(50-3.50x)[/tex]

Amount left with David after x days = [tex]\$(100-6x)[/tex]

According to question,

Amount left with Daniel after x days > Amount left with David after x days

[tex]50-3.50x>100-6x[/tex]

So, he inequality that satisfies the situation is [tex]50-3.50x>100-6x[/tex]

Option C is correct

Answer: i say B is correct

Answer:

B  -->  y is 1/3 of x

Step-by-step explanation:

x:y is 3:1

=>  x is bigger than y

=>  x is 3x bigger than y

=>  x = 3 lots of y

=>  [tex]x = 3y[/tex]

=>  [tex]\frac{x}{3} = y[/tex]

=>  [tex]\frac{1}{3} x = y[/tex]

Therefore y is [tex]\frac{1}{3}[/tex] of x

This means that B is correct

Answer:

The three angles form a "linear triplet" ,  so their measures must add up to [tex]180^o[/tex]

Step-by-step explanation:

Notice that the three angles add up to cover half a circle (therefore 180 degrees of angle. Such type of angle combination is called a "linear triplet" since they add up to give a straight line.

Answer:

The answer would be 33x - 15

Answer:

-7-(-4)= -3

Step-by-step explanation:

Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive.

Answer: the system of inequalities are

x + y ≤ 14

18x + 38y = 342

Step-by-step explanation:

Let x represent the number of iPad chargers sold.

Let y represent the number of keyboards sold.

At the end of the day, he knows he sold a maximum of 14 items. This is expressed as

x + y ≤ 14

If he

charged $18 for each iPad charger (x) and $38 for each keyboard (y) and earned a total of $342, the expression would be

18x + 38y = 342

Answer:

The triangles are Similar Triangles

Step-by-step explanation:

The corresponding angle are NOT proportional

The ratios of corresponding sides ARE equal.

The corresponding sides are NOT congruent.

The corresponding angle HAVE same measure

Two triangles are said to be similar triangle when they have the same shape but not necessarily the same size.

Which means that if two triangle have there corresponding angles congruent, and if there corresponding sides are in ratio, they are considered as Similar Triangle.

Corresponding angle:

∠H = ∠E

∠G = ∠F

∠I = ∠D

All angle are congruent

Ratio of Corresponding sides:

16/3.2 : 15/3 : 10/2

5:5:5

Hence Proved

Question: What can be concluded about these triangles? Check all that apply. Answer:  B,D,and E.

Answer:

332.64 m²

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 26.4 and h = 12.6 , thus

A = 26.4 × 12.6 = 332.64 m²

Answer:

A

Step-by-step explanation:

Answer:

a) 2*a*b - a/b

b)  c² + d + 2*c*d

c)  c + c²

d) (1 + b)/(2*b)

e)  p*q - 3*(p+q)

f) n²/(n+5)³

Step-by-step explanation:

We can divide each statement into its parts, as follows:

a) The difference between:

b) The sum of:

c) The sum of:

d) The quotient of:

e)

f) The quotient of:

All the algebraic expressions are written as,

a) 2ab - (a/b)

b) c² + d + 2cd

c)  c + c²

d) (1 + b)/(2b)

e)  pq - 3(p+q)

f) n²/(n+5)³

Used the method of a mathematical expression,

Mathematical expression is defined as the collection of numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, simplify all the expressions for mathematical form as,

a) The difference between twice the product of a and b and the quotient of these numbers.

Here, twice the product of a and b is,

2 × (ab)

And, the quotient of these numbers is,

a/b

Hence, it can be written as,

[tex]2ab - \dfrac{a}{b}[/tex]

b) The sum of squares of c and d increased by twice their product.

Here, d increased by twice their product is,

d + 2cd

And, The sum of squares of c and d increased by twice their product is,

c² + (d + 2cd)

c) The sum of a number c and its square is,

c + c²

d) Now, the number that is 1 greater than a number b is,

1 + b

And the number that is twice as large as b,

2b

So, The quotient of the numbers,

(1 + b)./2b

e) Now, The product of two numbers, p, and q is,

p × q

And, it is decreased by three times their sum:

p × q - 3 (p+q)

pq - 3 (p + q)

f) Now, the square of a number n is, n²

and the cube of n increased by 5 is, (n+5)³

So, The quotient is,

n² / (n + 5)³

Step-by-step explanation:

4x² + 11x - 3 = 0

(4x-1)(x+3) = 0

x = 1/4, -3

Answer:

x = -3 or x = 1/4

Step-by-step explanation:

Please see the graph in the attachment.

4 x^2 + 11 x - 3= 0

4 (x + 3) (x - (1/4)) = 0

(x + 3)= 0 or (x - (1/4))= 0

x = -3 or x = 1/4

ANSWER:

1.9

EXPLANATION:

Volume of a pyramid = V= lwh/3

V= Volume

L= Length

W= Width

to get length we divide 5 by 4 which is 1.25

therefore V= 1.25×1.25×3.6/3

V= 1.89

1.89 to the nearest tenth is 1.9
