2. You flip a coin two times. What is the probability that you get heads each
time?
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!

Mr. W is having a yard sale, where he is selling iPad chargers and wireless keyboards. At the
end of the day, he knows he sold a maximum of 14 items, and he earned a total of $342. If he
charged $18 for each iPad charger (x) and $38 for each keyboard (y), write a system of
inequalities that models this situation,
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

5
in
5 in and the height of the pyramid is
3.6
in
3.6 in. Round your answer to the nearest tenth of a cubic inch.
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
What is the value of b?
A. 100
B. 90
C. 80
Answer: the answer is C. 80°
Step-by-step explanation:
= 360 - 110 - 90
=160°
b=1/2 (160)
b=80°
Answer:
C. 80 degrees
Step-by-step explanation:
The measure of the given arcs are 90 and 110.
Subtract those values from 360
= 360 - 90 -110
= 160
The angle b is half of 160 degrees, the measure of the arc that intercepts it.
Therefore, it measures 80 degrees.

A = 26.4 × 12.6 = 332.64 m²
find the x in the triangle
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]

The corresponding angles are proportional. The ratios of the corresponding sides are equivalent. The corresponding sides are congruent. The corresponding angles have the same measure. DE corresponds to IH.
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

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

(08.01) Line H is represented by the following equation: 2x + 2y = 8 What is most likely the equation for line K so the set of equations has infinitely many solutions? x + 2y = 2 x + y = 4 2x + y = 6 x − y = 8
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

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]
