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.
Can someone help me will give brainliest thanks (:
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
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

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.
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 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

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.
