Answer:
1.4 or 30.8
Step-by-step explanation:
1.4 is for regular math because it's basically 16.1 - 14.7
30.8 is for KCO or Keep Change Opposite (Beginners math)
Basically it would turn the equation into 16.1 + 14.7
You can use either but if you aren't sure ask your teacher about the strategy.
Hope this helps and if not tell me your strategy.
What is the length of the hypotenuse of a right triangle whose legs have lengths of 5 and 12?
a)13
b)15
c)17
Answer:
Tha answer is A.
Step-by-step explanation:
Given that hypotenuse of a triangle is the longest length so you have to apply Pythagoras Theorem :
hypo² = side² + side²
hypo² = 5² + 12²
hypo² = 25 + 144
hypo² = 169
hypo = √169
hypo = 13 units
A weatherman predicted 17 inches of snow. The town actually got 1 and 1/2 feet of snow. By what percent was the weatherman’s prediction off?
Answer:
1 1/2 feet of snow= 18 inches
17/18 is around .94 so there’s .06 that the weatherman was off on.
.06 = 6%

Answer:
7/8 is greater than 2/4
Step-by-step explanation:
In this question basically, what we are trying to do is to compare fractions and state which is greater or less.
The first fractions in the question is;
7/8 _ 2/4
Now, one of the best ways to go around comparing fractions is looking at the denominators.
In this question, the denominators in the fractions are 8 and 4.
The next thing to do here is to multiply the numerator and the denominator of the first by 4 and the numerator and the denominator of the second by 8. This makes it possible for us to have the same denominator in both fractions and thus compare both fractions directly.
Thus, what we have would be;
7/8 = 7/8 * 1 = 7/8 * 4/4 = 28/32
Now for the fraction;
2/4 = 2/4 * 1 = 2/4 * 8/8 = 16/32
We can see they both have a common denominator and we can directly compare their numerators.
Obviously, 28 is greater than 16 and this makes a case for the fact that 7/8 is greater than 2/4
So what we have in the blank is ; is greater than
Kindly note that the other part of the question that talks about shading circles is same as saying 7/8 and 2/4

Consider this equation and the steps taken to solve it.
–9(a – 5) = –18 (distribute)
–9a + 45 = –18 (subtract 45)
–9a = –63 (divide by –9)
a = 7
What steps might you take to verify the solution? Check all that apply.
A) Substitute 7 for a.
B) Pick any value for a and substitute.
C) Simplify the equation after substituting the value for a.
D) Verify that a = 7 is correct when the result is a true statement.
E) Verify that a = 7 is correct when the result is a false statement.
Answer:
C

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.
On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.

$2.99 picture frame; 100% markup
Answer:
5.98
Step-by-step explanation:
2.99 * 1= 2.99
2.99+2.99= 5.98
First you had to multiply 2.99 by 1 because 100% in decimal is 1.
You get 2.99 and you add it to the original price.
And that is how you get 5.98

which statement correctly compares the function shown on this graph with the function y=6x-1
Answer:
D.
Step-by-step explanation:
The function shown on the graph is y = 5x - 6 and it is being comapred to y = 6x - 1. The function shown on the graph has a smaller rate of change because 5x < 6x. The starting point of the function shown on the graph is also lower since - 6 < - 1.
The statement correctly compares the function shown on this graph with the function y=6x-1 has a smaller rate of change.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
The function given on the graph is y = 5x - 6 and it is being comapred to the function y = 6x - 1.
Slope intercept form of a line is 5 ...(i)
We have,y = 6x - 1. ...(ii)
On comparing (i) and (ii), we get;
m= 6 , b = -1
The Slope of function is 6 and y-intercept is -1.
Since,5x < 6x , the function shown on the graph has smaller rate of change and a lower starting point.
The statement correctly compares the function shown on this graph with the function y=6x-1 has a smaller rate of change.

Find the equation of the line that is
perpendicular to the line y = 2x 5. (If you solve this I’ll make you brain list)
Answer:
y = ½x + 6.
Step-by-step explanation:
You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.
