Answer:
4 problems
Step-by-step explanation:
(I'm going to type a lot, but it isn't at all hard when you really understand and get the hang of it) If you are assigned 32 math exercises for homework and you complete 87.5% of them, this means that the problem is not asking for 87.5 % of 32, but what is left after you finish 87.5%, which means we should subtract 87.5 from 100. 100-87.5=12.5. 12.5% now represents the percent of the 32 original questions we have left to do after dinner. So, now we need to create a proportion. 12.5% means 12.5% out of 100%, with the 100% meaning 32, because that is the total amount of questions we have. so, this means we have [tex]\frac{12.5}{100}[/tex]. To use this to solve our problem, we have to act as if the 32 also represents 100%. So, we have to multiply this fraction ([tex]\frac{12.5}{100}[/tex]) by [tex]\frac{x}{32}[/tex] so that the 12.5% out of 100 lets us see how many problems 12.5% out of 100% would represents the remaining questions out of 32. so, we would solve for x (x representing the questions left to do after dinner.) So, we would form this equation and solve for x. -->[tex]\frac{12.5}{100} =\frac{x}{32}[/tex]. Now, we would cross multiply, then divide. So we would first multiply 12.5 times 32. This would give us 400. Then, we divide 400 by the 100, which gives us 4, which means that we have 4 problems left to do after dinner.
The temperature at 6:00 P.M. was 68°F. This was 5°F lower than the temperature at 3:00 P.M. The temperature at 1:00 P.M. on that day was 3°F higher than the temperature at 3:00 P.M. What was the temperature at 1:00 P.M.?
Which of the angles in the figure are supplementary to Ð5?
Answer:
Option C) Angle 6 and 7 only
Step-by-step explanation:
Two angles are called supplementary when their measures add up to 180 degrees.
So here the angle supplementary to Angle 5 would be 6, since adding both would get us 180 degrees. Then there's angle 7 which would also give us 180 degrees when added to angle 5.
Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.
Growth factor Levels
Lighting Low, Medium, High, Very high
Age month, months, months, months, months
Temperature , , ,
She wants to find the number of ways of combining one level from each of the growth factors. How many ways are there?
Answer:
80
Step-by-step explanation:
For these types of counting problems, just multiply all of the levels.
For example, this would be
4 choices
5 choices
4 choices
Multiply 4*5*4, and you get 80.
Total number of ways of combining one level from each of the growth factors is equals to 80.
What is fundamental principle of counting?" As per fundamental principle of counting if first event has 'm' number of possible outcomes , second has 'n' number of possible outcomes then total number of ways are m× n ."
According to the question,
Number of growth factors =3
First growth factor: Lightening
Second growth factor: Age
Third growth factor : Temperature
As per the data given we have,
Number of levels in lightening 'm'= 4
Number of levels in age 'n'= 5
Number of levels in temperature 'p' =4
Substitute the value as per the definition of fundamental principle of counting
Total number of ways = m × n × p
= 4 × 5 × 4
= 80 ways
Hence, total number of ways of combining one level from each of the growth factors is equals to 80ways.

Area of a trapezoid: A=(h)(a+b)/2. To see where h, a, and b are located, see the reference image below. Always remember that a is the shorter end and b is the longer end. Since each grid mark goes by 2, we can use the graph to find the missing variables.
PINK trapezoid:
h = 8, a = 4, b = 8A = 8(4 + 8)/2 = 48 units squaredBLUE trapezoid:

Karen just bought 6 bags of 16 cookies each. She already had 9 cookies in a jar. How many cookies does Karen have now?
Answer:
105 cookies
Step-by-step explanation:
We can model Karen's cookie situation like so:
#TotalCookies = #RecentlyBought + #AlreadyHad
We know that Karen already had 9 cookies in a jar, so it now looks like.
#TotalCookies = #RecentlyBought + 9
The number she recently bought, involves multiplication. So she bought 6 bags of 16 cookies. That's 6 x 16 = 60 + 36 = 96
#TotalCookies = 96 + 9 = 105 cookies

Zoe considers the lunch choices as she looks at the menu. What is the probability that she will choose cheese pizza, apple, milk?
Meal: Cheese Pizza, Cheeseburger, Hotdog, Salad
Side: Banana, Apple, Yogurt
Beverage: Milk, Water, Juice
Answer:
1/36
Step-by-step explanation:
Meal: 4 choices
Side: 3 choices
Beverage: 3 choices
Total number of possible combinations: 4 × 3 × 3 = 36
The specific combination of cheese pizza, apple, and milk is 1 of the 36 possible choices.
p(cheese pizza, apple, milk) = 1/36
Answer:
e
Step-by-step explanation:
We first have to find out how many outcomes there are in total. That means finding out how many meals, sides, and beverages there are.
Meals: cheese pizza, cheeseburger, hotdog, and salad (4)
Sides: banana, apple, and yogurt (3)
Beverages: milk, water, and juice (3)
4 x 3 x 3 = 36
There are 36 possible outcomes.
We need to find the probability that Zoe will choose cheese pizza, an apple, and milk. Those are three outcomes.
The probability is 3/36.
The fraction 3/36 can be simplified to 1/12.

A school fundraiser has a minimum target of $600. Faculty donated $200 and there are 10 student clubs that are participating with different activities. Write an inequality showing the amount money each club should raise to meet the minimum target. Use f for the amount of money that each club raises.
Answer:
600=10f+200
Step-by-step explanation:
since $600 is the target, and the faculty already donated 200 dollars 200 would be the y intercept. since f is the amount of money that the clubs should raise, we can set that as 10 f since there are 10 clubs and since it needs to be inequality, it would be written in the y = mx + b format. hope this helps!

You have a coin and a dice. Flipping the coin, you can either get heads or tails facing up. There are 6 numbers on the dice, numbered 1-6. What is the probability of flipping tails and getting the numbers 3 or 4 on the dice?
Answer:
3 = (50.000%)
4 = (66.667%)
Step-by-step explanation:
3 out of 6 = 3/6
4 out of 6 = 4/6
3/6 in decimal form is 0.5
4/6 in decimal form is 0.6666 (the six repeats forever)
0.5 out of 1 is 50%
0.6666 (the six repeats forever) out of 1 is about 66.667%
0.5 = (50.000%)
0.66667 (rounded) = (66.667%)
A circular field has a diameter of 50 yards. If a fence needs to be built to go around the field, how many yards of fencing are needed?
157 yards
314 yards
100 yards
1962 yards
Answer:
A.
Step-by-step explanation:
A fence is needed for the circular field.
Circumference is basically perimeter but for circles.
Knowing this information, we can use the formula for circumference.
C = [tex]\pi[/tex]d
C = (3.14)(50)
C = 157
