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

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.
uh looking at the other answer that one is probs right

hydrochloric acid solution and
70% hydrochloric acid solution
must be mixed to obtain 20
ounces of 50% hydrochloric acid
solution?
Answer:
8 ounces of 20%12 ounces of 70%
Step-by-step explanation:
Let 'x' be the number of ounces of 20% solution'y' be for the 70%
solutionSince the the mix is 50% of 20 ounces then:x + y = 200.20x +
0.70y = 0.50(20)From the 1st equation solve for xx = 20 - ySubstitute it to
the 2nd equation0.2(20-y) + 0.7y = 104 - 0.2y + 0.7y = 100.5y = 10-40.5y =
6y = 12Substitute to x = 20 - yx = 20 - 12x = 8

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!

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:
h = 6, a = 4, b = 10A = 6(4 + 10)/2 = 42 units squaredHope this helps!

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
Karen loves cookies!
Answer:
105 cookies
Step-by-step explanation:
Given:-
Total cookies he have already :- 9cookies bought :- 6 bags each of 16 cookiesTo find:-
Total no. of cookies he have nowSolution:-
total no. of cookies :- new cookies + old cookies
= 6×16+9
105 cookies

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%)

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.
