If a man walks at the rate of 3 feet per second, how many minutes will it take him to walk 5760 feet?
Answer:
32 minutes
Step-by-step explanation:
There are 60 seconds in a minute
That means we will need to know how many feet he walks in a minute
So we would do 3 x 60 which equals 180 so he walks 180 ft per miute
Now we need to figure out how many minutes it took for him to walk 5760 ft.
So we would do 5760 ÷ 180 which equals 32
So the aswer is 32 minutes for him to walk 5760 ft.
Hope this helps

In how many ways can a quality-control engineer select a sample of3 transistors for testing frm a batch of 100 transistors?
Answer:
161700 ways.
Step-by-step explanation:
The order in which the transistors are chosen is not important. This means that we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
3 transistors from a set of 100. So
[tex]C_{100,3} = \frac{100!}{3!(100-3)!} = 161700[/tex]
So 161700 ways.

what equation can be formed to determine the two numbers.
Answer:
If one is given a quadratic equation in the form x2 + bx + c = 0, the sought factorization has the form (x + q)(x + s), and one has to find two numbers q and s that add up to b and whose product is c (this is sometimes called "Vieta's rule" and is related to Vieta's formulas).

Each side of a cube is 4 inches long. What surface area of the cube
Answer:
96 in^2
Step-by-step explanation:
This is because u have to multiply the two bases and the lateral sides to get your area
Answer:
96
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces.
Area = l x w
4 x 4 = 16
16 x 6 = 96

Deanna says a common denominator for ¼ and ⅙ is 20. Do you agree? Explain why or why not
Answer:
no
Step-by-step explanation:
4 IS a factor of 20
BUT

x=-3y+3
x-3y=-15
Answer:
x = -6
y = 3
Step-by-step explanation:
Since we are given what x equals, we will plug that in first to the second equation.
(-3y+3) - 3y = -15
Solve by combining like-terms and isolating y.
-6y + 3 = -15
-6y = -18
y = 3
Now plug in y to the first equation to solve for x.
x = -3(3) + 3
x = -9 + 3
x = -6

b is the midpoint of ac. if ab=8x-7 bc=6x+7 find ac
Answer: AC = 98
Step-by-step explanation:
A midpoint is a point on a line segment that divides it into two equal parts.
This means AB = BC
AB = 8x - 7
BC = 6x + 7
AB = BC
8x - 7 = 6x + 7
Solve this to find x
Add 7 to both sides
8x = 6x + 14
Subtract 6x from both sides
2x = 14
Divide both sides by 2
x = 7
Now AC = AB + BC
AC = AB + BC
AC = 8x - 7 + 6x + 7
AC = 14x
Substitute 7 for x
AC = 14(7)
AC = 98
Hope this helps!

The union representing the Bottle Blowers of America (BBA) is considering a proposal to merge with the Teamsters Union. According to BBA union bylaws, at least three-fourths of the union membership must approve any merger. A random sample of 2,000 current BBA members reveals 1,600 plan to vote for the merger proposal. What is the estimate of the population proportion
Answer:
The answer is "(0.782, 0.818)".
Step-by-step explanation:
computing the sample proportion:
[tex]p=\frac{x}{n}= \frac{1,600}{2000}=0.80 \\\\[/tex]
[tex]\text{Computing the} \ 95\% \ \ C.I \\\\[/tex]
[tex]C.I= p \pm Z_{\frac{\alpha}{2}}\sqrt{\frac{P(1-p)}{n}}[/tex]
[tex]= 0.80 \pm 1.96 \sqrt{\frac{0.80(1-0.80)}{2000}} \\\\= 0.80 \pm 1.96 \sqrt{\frac{0.80(0.20)}{2000}} \\\\= 0.80 \pm 1.96 \sqrt{\frac{0.16}{2000}} \\\\ = 0.80 \pm 1.96 \sqrt{0.00008} \\\\=0.80 \pm 0.18 \\\\= (0.782, 0.818)[/tex]
conclusion:
Since the interval calculation contains higher values than 75 percent of its union membership, the merger proposal is likely to pass.

Answer:
12. median: AD; altitude: CE; midsegment: none
13. x = 2
Step-by-step explanation:
12. The median joins a vertex with the midpoint of the opposite side. Point D is identified as the midpoint of BC, so AD is the median.
An altitude is a segment from a vertex that is perpendicular to the opposite side. CE is an altitude of this triangle.
A midsegment joins midpoints of adjacent sides of the triangle. Only one midpoint (D) is identified in this triangle, so no midsegment can be named.
Additional comment: BF is an angle bisector. Perhaps that is what is intended in part (c). You may want to report this question to your teacher.
__
13. The base segment is twice the length of the midsegment:
2(5x -3) = x +12
10x -6 = x +12 . . . . . eliminate parentheses
9x = 18 . . . . . . . . . . add 6-x
x = 2 . . . . . . . . . . . . .divide by 9
