A recent survey revealed that for every 13 people who prefer football, 7 people prefer basketball. There are 154 people at an event who prefer basketball. How many prefer football?
Answer:
286
Step-by-step explanation:
Given that:
For every 13 people who prefer football ; 7 prefer basket ball
At an event;
Number who prefer basketball = 154
Number who prefer football :
[(Total who prefer basketball) ÷ 7] * 13
(154 / 7) * 13
= 22 * 13
= 286
Anne made a recipe for miniature bread loaves that called for StartFraction 7 Over 8 EndFraction of a cup of whole-wheat flour. If the recipe made 7 equal-sized loaves of bread, how many cups of whole-wheat flour did each loaf contain? StartFraction 1 Over 8 EndFraction of a cup StartFraction 1 Over 7 EndFraction of a cup StartFraction 8 Over 49 EndFraction of a cup StartFraction 49 Over 8 EndFraction cups
Answer:
1/8
Step-by-step explanation:
So if the entire recipe makes 7 loaves and calls for 7/8 of a cup, you would need to split the 7/8 cups flour into 7. 7/8 ÷ 7=1/8.
Option A: 1/8 of a cup

Which reason best explains why living things need carbon?
Carbon bonds are a source of energy.
Carbon levels reduce global temperatures.
Carbon acts as an important solvent.
Carbon is everywhere.
Answer:
Carbon Bonds are a source of energy
Step-by-step explanation:
If this were a free answer response question, I would say that the reason would be that carbon can form bonds with many other element, but it wasn't there, so the first option is the closest to my answer.
Answer:
I would go with A. it's the only one that makes sense

Evaluate the expression:
for y = 2 + 3x when x=4. What does y=?
Answer:
y = 14
Step-by-step explanation:
Plug in 4 as x into the equation:
y = 2 + 3x
y = 2 + 3(4)
Simplify:
y = 2 + 12
y = 14
So, when x = 4, y = 14.

Seema bought a new pair of jeans that were on sale. The original price of the jeans was $56. The store had marked them down by 25 percent, and Seema had a 20 percent off coupon as well. Original price: $56 25% 25% 25% 25% $42 20% 20% 20% 20% 20% $8.40 $8.40 $8.40 $8.40 What was the price of the jeans before tax? $8.40 $16.80 $33.60 $42.00
Answer:
C.) 33.60
Step-by-step explanation:
OMP. = $56
D. = 25%
0.25 * $56 = $14
SP. = $56-$14=$42
CD. = 20% of Selling price
= 0.20 * $42 = $8.40
FSP. = $42-$8.40 = $33.60

Write the equation (1,2) in a point-slope form.
y-2= m(x-2)
Step-by-step explanation:
Y-y1=m(x-x1)
it's just plugging in the points to point slope formal
Answer:
y - 2 = m(x - 1)
Step-by-step explanation:
point slope form: y - y₁ = m(x - x₁)
y - 2 = m(x - 1) take note that slope is unknown.

which statement correctly compares the function shown on this graph with the function y=6x-1
Given:
The function is
[tex]y=6x-1[/tex]
To find:
The statement that correctly compares the function shown on this graph and the given function.
Solution:
Slope intercept form of a line is
[tex]y=mx+b[/tex] ...(i)
where, m is slope and b is y-intercept.
We have,
[tex]y=6x-1[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=6,b=-1[/tex]
Slope of function is 6 and y-intercept is -1.
The graph passes through (0,-6) and (2,4). So, the y-intercept is -6 and slope is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{4-(-6)}{2-0}[/tex]
[tex]m=\dfrac{10}{2}[/tex]
[tex]m=5[/tex]
Since, 5<6 and -6<-6, therefore, the function shown on the graph has smaller rate of change and a lower starting point.
Hence, the correct option is D.

You’ve studied and now you’re geared up for the ACT math section (whoo!). But are you ready to take on the most challenging math questions the ACT has to offer? Do you want to know exactly why these questions are so hard and how best to go about solving them? If you’ve got your heart set on that perfect score (or you’re just really curious to see what the most difficult questions will be), then this is the guide for you.
We’ve put together what we believe to be the most 21 most difficult questions the ACT has given to students in the past 10 years, with strategies and answer explanations for each. These are all real ACT math questions, so understanding and studying them is one of the best ways to improve your current ACT score and knock it out of the park on test day.
Brief Overview of the ACT Math Section
Like all topic sections on the ACT, the ACT math section is one complete section that you will take all at once. It will always be the second section on the test and you will have 60 minutes to completed 60 questions.
The ACT arranges its questions in order of ascending difficulty. As a general rule of thumb, questions 1-20 will be considered “easy,” questions 21-40 will be considered “medium-difficulty,” and questions 41-60 will be considered “difficult.”
The way the ACT classifies “easy” and “difficult” is by how long it takes the average student to solve a problem as well as the percentage of students who answer the question correctly. The faster and more accurately the average student solves a problem, the “easier” it is. The longer it takes to solve a problem and the fewer people who answer it correctly, the more “difficult” the problem.
(Note: we put the words “easy” and “difficult” in quotes for a reason—everyone has different areas of math strength and weakness, so not everyone will consider an “easy” question easy or a “difficult” question difficult. These categories are averaged across many students for a reason and not every student will fit into this exact mold.)
All that being said, with very few exceptions, the most difficult ACT math problems will be clustered in the far end of the test. Besides just their placement on the test, these questions share a few other commonalities. We'll take a look at example questions and how to solve them and at what these types of questions have in common, in just a moment.
But First: Should You Be Focusing on the Hardest Math Questions Right Now?
If you’re just getting started in your study prep, definitely stop and make some time to take a full practice test to gauge your current score level and percentile. The absolute best way to assess your current level is to simply take the ACT as if it were real, keeping strict timing and working straight through (we know—not the most thrilling way to spend four hours, but it will help tremendously in the long run). So print off one of the free ACT practice tests available online and then sit down to take it all at once.
Once you’ve got a good idea of your current level and percentile ranking, you can set milestones and goals for your ultimate ACT score. If you’re currently scoring in the 0-16 or 17-24 range, your best best is to first check out our guides on using the key math strategies of plugging in numbers and plugging in answers to help get your score up to where you want it to. Only once you've practiced and successfully improved your scores on questions 1-40 should you start in trying to tackle the most difficult math problems on the test.
If, however, you are already scoring a 25 or above and want to test your mettle for the real ACT, then definitely proceed to the rest of this guide. If you’re aiming for perfect (or close to), then you’ll need to know what the most difficult ACT math questions look like and how to solve them. And luckily, that’s exactly what we’re here for.

Find the value of x and the value of y.
A. X-4, 7-8
B. x - 7,7=43
C. x = 4√3, 7-72
D. x=753, y = 4√2
Answer:
[tex]x= 7, y=4\sqrt{2}[/tex]
Correct option B.
Step-by-step explanation:
The diagram shows a trapezoid with a base angle of 45° and the other base angle of 90°.
We have completed the diagram to draw a perpendicular line over the base of height h=4. A triangle is formed with an angle of 45°.
Recall a right triangle with angles of 45° is isosceles, thus the base and the height are h=4. Please check the diagram below.
For that triangle, we apply Pythagora's Theorem:
[tex]y^2=4^2+4^2=2*4^2[/tex]
Thus:
[tex]y=\sqrt{2*4^4}=4\sqrt{2}[/tex]
[tex]y=4\sqrt{2}[/tex]
The base of the trapezoid x is h + 3 = 7
Thus:
[tex]\mathbf{x= 7, y=4\sqrt{2}}[/tex]
Correct option B.
