A recipe that serves four calls 2 1/4 cups of butter. How many cups of butter are needed to serve 12
Answer:
6 3/4 cups.
Step-by-step explanation:
If 2 1/4 cups serves 4, you need to serve 12 so you would multiply the amount of butter by 3 and get 6 3/4 cups of butter.

A fence is going to diagonally divide a 30 foot by 24 foot rectangular garden in half. Approximately how long, in feet, should the fence be?
19
27
38
46
54
Answer:38
Step-by-step explanation:
The diagonal of a rectangle creates the hypotenuse of a right triangle. Use the Pythagorean theorem, a2 + b2 = c2, where a = 30 ft and b = 24 ft, to calculate the length of the fence c.
a2 + b2 = c2
302 + 242 = c2
900 + 576 = c2
1476 = c2
38.42 ≈ c
The fence should be about 38 feet long. Isn't it strange to divide a garden in half diagonally with a fence? It doesn't seem to serve the purpose of keeping intruders out. It doesn't seem to serve any purpose, really.
Jan walks each morning for exercise. She takes a drink of water as she completes every 3/4 of a mile. She walks a total of 4 1/2 miles. How many times does she take a drink?
Answer:
Jan takes a drink 6 times.
Step-by-step explanation:
The information provided is:
Jan takes a drink of water as she completes every 3/4 of a mile. She walks a total of 9/2 miles.Compute the number of times Jan takes a drink as follows:
[tex]\text{Number of times Jan takes a drink}=\frac{\text{Number of miles walked}}{\text{Interval for a drink}}[/tex]
[tex]=\frac{9/2}{3/4}\\\\=6[/tex]
Thus, Jan takes a drink 6 times.

The wheel on Bellas unicycle has a circumference of 0.9 yards how many will he travel if the wheel of his unicycle completes 1000 rotations
Answer:
900 yards.
Step-by-step explanation:
The circumference of a circle is the length of the circle's side.
Hence, for every one rotation, the wheel rotates once, and the unicycle travels the distance of the wheel's circumference.
Therefore, for 1000 rotations, and every rotation travelling 0.9 yards, the distance traveled would be 1000 * 0.9 = 900 yards.
Hope this helped!

Write an equation in slope intercept form that goes through (-1,6) and (3,-2)
First, we need to use slope formula* to find the slope.
[tex]m = \frac{-2 - 6}{3 - (-1)} = \frac{-8}{4} = -2[/tex]
Second, we use the slope we found and ONE of the 2 points listed and plug it into slope-intercept form** to solve for b.
Here is what we have so far:
[tex]m = -2[/tex]I'm going to use this point:
[tex]x = 3[/tex][tex]y = -2[/tex]Here is how to find b:
[tex]-2 = -2(3) + b\\\\-2 = -6 + b\\\\4 = b[/tex]
Finally, we put all of it together and we have our equation.
[tex]y = -2x + b[/tex]
*Slope formula: m = y₂ - y₁/x₂ - x₁
**Slope-intercept form: y = mx + b
A drawer of loose socks contains 2 red socks, 2 green socks, and 6 white socks. What best describes how to determine the probibility of pulling a white sock, not replacing it, then pulling out another white sock?
Answer:
Probability = 1/3
Step-by-step explanation:
The drawer of loose socks contains 2 red socks, 2 green socks, and 6 white socks.
This is a total of 10 socks.
Probability of pulling a white socks = 6/10
Since it is not replaced, it means we have 5 white socks left out of a total of 9 now.
Probability of pulling out another white socks = 5/9
Thus;
The combined probability is;
6/10 × 5/9 = 30/90 = 1/3
Hellooooo!
My Answer:
The answer is letter C.
The Explanation:
The probability that the first sock is white is 6/10 and the second one is white is 5/9, so the probability of choosing a pair of white socks is 30/90 = 1/3.

What is the value of c in this linear system?
A) 1
B) -3
C) -1
D) 2
9514 1404 393
Answer:
B) -3
Step-by-step explanation:
There are methods for finding only c. Cramer's rule is one of them. It involves finding two determinants and taking their ratio. Here, we choose a more ad hoc approach. It appears that the value of b can be found by combining the last two equations.
(1/2)(2a +4b -2c) -(a -3b -c) = (1/2)(12) -(-4)
5b = 10
b = 2
Now, we can substitute this value into the first two equations. This gives ...
5a +c = -8
a - c = 2
Subtracting 5 times the second from the first gives ...
(5a +c) -5(a -c) = (-8) -5(2)
6c = -18 . . . . simplify
c = -3 . . . . . . divide by 6
The value of c is -3.
If G is the circumcenter of triangle ABC, find CG and FB. Round to the nearest tenth if necessary.
PLS HELP FOR GEOMETRY
9514 1404 393
Answer:
CG = 19
FB = 14.7
Step-by-step explanation:
The circumcenter is equidistant from the triangle vertices, so GA = GB = GC.
The length of GA is given, so we have ...
GA = 19 = CG
__
Then the Pythagorean theorem can be used to find FB.
FB² +FG² = GB²
FB² = GB² -FG² = 19² -12² = 217
FB = √217 ≈ 14.7

2. Toss 4 times Imagine tossing a fair coin 4 times . (a ) Give a probability model for this chance process . (b) Define event B as getting exactly three tails . Find P(B)
Answer:
If a coin is tossed 4 times; number of possible outcomes = (2^4) = 16. 3 heads and 1 tail can occur from 4 tosses in (4C3)*(1C1) = 4*1 = 4 ways. So, the probability = (4 / 16) = (1 / 4) = 0.25.
i didnt really understand the question but hope this helps
According to the information given, we have that:
a) A binomial model with [tex]p = 0.5[/tex] and [tex]n = 4[/tex] should be used.b) P(B) = 0.25.For each coin, there are only two possible outcomes, either it is heads, or it is tails. The result of the flip of a coin is independent of any other flip, hence, the binomial distribution is used to solve this question.
Binomial probability distribution[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.Item a:
The coin is tossed 4 times, hence [tex]n = 4[/tex].It is a fair coin, hence equally as likely to be heads and tails, which means that [tex]p = 0.5[/tex].Hence, a binomial model with [tex]p = 0.5[/tex] and [tex]n = 4[/tex] should be used.
Item b:
P(B) is P(X = 3), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{4,3}.(0.5)^{3}.(0.5)^{1} = 0.25[/tex]
Hence, P(B) = 0.25.
