A number raised to an exponent is the number multiplied by itself the number of times the exponent is.
The exponent is 3, so this means 0.25 is multiplied by itself 3 times.
0.25^3 = 0.25 x 0.25 x 0.25
Answer:0.100
Step-by-step explanation:
If you sed the rule of counting decimal places in the equation to find the number of decimal places in the answer you must not discard zeros too early. For example to multiply 0.25 by 0.4 you need 2+1 decimal places and the multiplication without a decimal point gives 0100. The answer is therefore 0.100.

What is ____ of the x-intercept is
The
always zero.
A . X-coordinate
B. Y-coordinate
The x-intercept is Y-coordinate always zero which is the correct answer that would be an option (B).
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is x-Intercept?The x-intercept is defined as an intercept that is located at the x-axis of the plane, is the location or coordinate from where the line crosses
The general form of the linear equation, where m and b are constants, is written as y = mx + b. . As a result, the value of the y-coordinate in the corresponding linear equation will always be zero when it crosses the x-axis.
The y-coordinate for the x-intercept and the x-coordinate for the y-intercept are both zero. Another name for the x-intercept is the horizontal intercept.
Therefore, the x-intercept is Y-coordinate always zero which is the correct answer that would be an option (B).

Find the value of each variable. What are x and y ?
Answer:
Step-by-step explanation:
since 105 + z is a straight line we know it equals 180 so we can use this equation
180 = 105 + z
simplify
75 = z
the since we know that all quadrilaterals equal 360 degrees we can add our two given number and z then subtract from 360:
102 + 85 + 75
= 262
now subtract
360 - 262
= 98
y = 98

A leaking pond loses 12 gallon of water in 23 hours How many gallons of water will it lose in 31 hours
Answer:
The volume of water the pond will lose in 31 hours is 17.71 gallons.
Step-by-step explanation:
Given;
Rate of water leakage, R = 12 gallon of water in 23 hours
[tex]R = \frac{12 \ gallons}{23 \ hours}[/tex]
In 31 hours the volume of water leaked is calculated as;
[tex]V = \frac{12 \ gallons}{21 \ hours} \times 31 \ hours\\\\V = 17.71 \ gallons[/tex]
Therefore, the volume of water the pond will lose in 31 hours is 17.71 gallons.

When flipping a coin once and rolling a six-sided die,
what is the probability of the coin landing on heads and rolling a multiple of three?
Answer:
Explanation: When you flip a coin there are two possible outcomes (heads or tails) and when you roll a die there are six outcomes(1 to 6). Putting these together means you have a total of 2×6=12 outcomes.
Find the value of x in the triangle shown
Answer:
5
Step-by-step explanation:
you need to use the Pythagorean theorem
a^2+b^2=c^2
a&b=sides
c=hypotonuse
plug the side values into the equation
4^2+3^2=c^2
16+9=c^2
25=c^2
you have to square root 25 to find c itself
c=5
Answer : would be 5
Because a triangle that has a sequence of the number 3 & 4, or 3 & 5, or 4 & 5 will always consider of the number 3,4 and 5.
Also if te triangle did consist of different numbers the Pythagorean theorem ( a^2 + b^2 = c^2 ) can be use.
So in this case it’ll be 3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^ 2
Then we square root both sides and the answe will be : 5 = c

Find x & y so that quadrilateral is a parallelogram. (Look at image) please help!!
Answer:
y = 2 and x = -3
Step-by-step explanation:
we know that opposite sides of a parallelogram are equal so
7y + 3 = 12y - 7
12y - 7y = 3 + 7
5y = 10
y = 10 / 5
y = 2
Now
-6x = -4x + 6
-6x + 4x = 6
-2x = 6
x = 6 / - 2
x = - 3

Answer:
$10 coins: 21
$20 coins: 24
Step-by-step explanation:
So we can create 2 equations where
x = number of $10 coins
y = number of $20 coins:
x + y = 45
10x + 20y = 690
we can move equation 1 around so that we can get a value of x
x = 45 - y
now we can substitute x into the second equation
10(45 - y) + 20y = 690
450 - 10y + 20y = 690
10y = 240
y = 24
Now plug in y back into the first equation
x = 45 - y
x = 45 - 24
x = 21
The top speeds for a sample of five new automobiles are listed below. Calculate the standard deviation of the speeds. Round to four decimal places. 170, 160, 130, 165, 125
Answer:
20.92
Step-by-step explanation:
Given the data:
X : 170, 160, 130, 165, 125
Standard deviation (s) :
s = √Σ((X - m)² / n)
m = mean
n = sample size
Mean , m = Σx/n
m = (170 + 160 + 130 + 165 + 125) / 5
m = 750/5
m = 150
((X - m)² / n - 1)
[(170-150)^2 + (160-150)^2 + (130-150)^2 + (165-150)^2 + (125-150)^2] / (5-1)
= 1750 / 4
= 437.5
s = √437.5
s = 20.9165
s = 20.92
Which one is a cheaper buy, a 24-cm by 24-cmn pizza for
7350.00 or a 30-cin diameter circular pizza for the same price.
Explain.
Answer:
The circular pizza is cheaper because you pay less money for a unit area of the pizza
Step-by-step explanation:
Step one:
given data
The dimension of the square pizza is
24 X 24 cm
The area is
= 576cm^2
Also, the dimension of the circular pizza is
DIameter = 30cm
radius = 30/2 = 15cm
The area is
= πr^2
=3.142*15^2
=706.95cm^2
Step two:
let us find the cost per area of each of the shape of the pizzas
For the square pizza the cost per area is
= 7350/576
=$12.76 per area
For the circular pizza, the cost per area is
= 7350/706.95
=$10.40 per area
For the second quarter of 2015, Apple sold 61.0 million iPhones. This represented a year- over-year increase of 40%. What were the sales for iPhone for the same quarter in the previous year (rounded to the nearest 10,000)?
Answer:
It sold 43.57 iPhones for the same quarter in the previous year.
Step-by-step explanation:
It sold 61.0 million iPhone, which is an increase of 40% over the value of the previous year x.
This can be interpreted as:
61 million is 140% = 1.4 of the previous year amount, that is, x. So
[tex]1.4x = 61[/tex]
[tex]x = \frac{61}{1.4}[/tex]
[tex]x = 43.57[/tex]
It sold 43.57 iPhones for the same quarter in the previous year.
