A. 1/12
B. 1/6
C. 1/4
D. 1/36
Answers
Answer:
C. 1/4
Step-by-step explanation:
3/6 * 3/6 = 1/2 * 1/2 = 1/4
The probability of rolling an even number on the first roll and an odd number on the second roll is equal to 1/4.
We have given that,
A single six-sided die is rolled twice.
We have to determine,
The probability of rolling an even number on the first roll and an odd number on the second roll.
What is the formula for probability?
The probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).
Therefore the,
Probability of rolling an even number on the first roll and an odd number on the second roll
= 3/6 * 3/6
= 1/2 * 1/2
= 1/4
The probability of rolling an even number on the first roll and an odd number on the second roll is equal to 1/4.

A car radiator needs a 40% antifreeze solution. The radiator now holds 14 liters of a 30% solution. How many liters of this should be drained and replaced with 100% antifreeze to get the desired strength?
Answers
Answer:
2.03 liters of 30% antifreeze should be drained and replaced with 100% antifreeze to get the desired strength.
Step-by-step explanation:
Since a car radiator needs a 40% antifreeze solution, and the radiator now holds 14 liters of a 30% solution, to determine how many liters of this should be drained and replaced with 100% antifreeze to get the desired strength the following calculation must be performed:
100 x 0.3 + 0 x 1 = 30
90 x 0.3 + 10 x 1 = 37
85 x 0.3 + 15 x 1 = 40.5
86 x 0.3 + 14 x 1 = 39.8
85.8 x 0.3 + 14.2 x 1 = 39.94
85.7 x 0.3 + 14.3 x 1 = 40.01
85.71 x 0.3 + 14.29 x 1 = 40
100 = 14
14.29 = X
14.29 x 14/100 = X
200.06 / 100 = X
2.03 = X
Therefore, 2.03 liters of 30% antifreeze should be drained and replaced with 100% antifreeze to get the desired strength.

Which expression gives the closest estimate of 228 – 179?
Answers
Answer:
show the picture
Step-by-step explanation:
The closest estimate of 228 - 179 is 49.
What is subtraction?Subtraction is a mathematical operation. Which is used to remove terms or objects in the expression.
Given:
The two numbers are 228 and 179.
128 and 179 are real positive integers.
And here we have to find the subtraction of 179 to 228.
In other words,
the difference between 228 and 179 is,
228 - 179
= 49
To verify the equation:
179 + 49 = 228.
That means, 49 is the required number.
And 49 is the whole number.
S0, 49 is the closest estimate.
Therefore, 49 is the required expression.

Answer:
-1/9
Step-by-step explanation:
We need to solve out and find out the value of p . The given equations is.
=> 2p + 1/ 5p + 6 = 1/7
=> 7 ( 2p + 1) = 5p + 6
=> 14p + 7 = 5p + 6
=> 14p - 5p = 6-7
=> 9p = -1
=> p = -1/9
• Hence the value of p is -1/9
Write the standard form equation (Ax + By + C =0) for a line that is perpendicular to
y= 2x + 7 and has the same y-intercept as the line y=5x - 5.
Put only the coefficients for A, B and C
Answers
Answer:
A = 1
B = 2
C = 10
Step-by-step explanation:
slope intercept form is
y = mx + b
m is the slope
b is the y-intercept
The slopes of parallel lines are negative reciprocals
------------------------------
y = 2x + 7
slope = 2
slope of perpendicular line is the negative reciprocal of 2
slope = -1/2
y = 5x - 5
y-intercept is -5
-----------------------
slope intercept form of perpendicular line
using slope = -1/2 and y-intercept = -5
y = -(1/2)x - 5
Change to standard form:
multiply both sides by 2
2y = -x - 10
Add x + 10 to both sides
x + 2y + 10 = 0
Therefor
A = 1
B = 2
C = 10
