If hot and cold water taps are turned on altogether, a bath is filled in three minutes but if the cold tap was only half opened it would take one minute forty eight seconds longer. How long would the hot tap alone take to fill the bath?
Answers
9514 1404 393
Answer:
12 minutes
Step-by-step explanation:
Let c and h represent the filling times for the cold and hot taps, respectively. When the cold tap is 1/2 open, we presume that means the filling time becomes 2c.
In terms of baths per minute, the relationships are ...
1/c + 1/h = 1/3
1/(2c) +1/h = 1/(3 +1.8) . . . . . 1:48 min:sec is 1.8 minutes
Subtracting the first equation from twice the second, we get ...
2(1/(2c) +1/h) -(1/c +1/h) = 2(1/4.8) -(1/3)
1/h = 2/4.8 -1/3 = 1/12
h = 12
It takes the hot tap 12 minutes to fill the tub alone.
Jennifer walks 9 blocks south and 5 blocks west. Approximately how many blocks is she from home if she were to take a direct path?
Answers
9514 1404 393
Answer:
10.3
Step-by-step explanation:
Assuming the blocks are square, we can use the Pythagorean theorem to find the diagonal distance.
d² = 9² +5² = 81 +25 = 106
d = √106 ≈ 10.3
Jennifer is about 10.3 blocks from home.

What is the binomial expansion of (2x – 3)5? (2x)5 – 15(2x)4 + 90(2x)3 – 270(2x)2 + 405(2x) – 243 (2x)5 + 15(2x)4 – 90(2x)3 + 270(2x)2 – 405(2x) + 243 (2x)5 + 15(2x)4 + 90(2x)3 + 270(2x)2 + 405(2x) + 243 2(x)5 – 30(x)4 + 180(x)3 – 540(2x)2 + 810(x) – 243
Answers
Answer:
c
Step-by-step explanation:
just got it correct
The value of binomial expansion of expression (2x - 3)⁵ is,
⇒ (2x)⁵ – 15(2x)⁴ + 90(2x)³ – 270(2x)² + 405(2x) – 243
We have to given that;
The expression is,
⇒ (2x - 3)⁵
Now, We know that;
The formula of binomial expansion is,
⇒ (x + y)ⁿ = (ⁿ₀) xⁿy⁰ + (ⁿ₁) xⁿ⁻¹y¹ + (ⁿ₂) xⁿ⁻²y² + ...... + yⁿx⁰
Hence, The value of binomial expansion of (2x - 3)⁵ is,
⇒ (2x - 3)⁵
⇒ (2x + (- 3))⁵
⇒ (2x)⁵ – 15(2x)⁴ + 90(2x)³ – 270(2x)² + 405(2x) – 243
Thus, The value of binomial expansion of expression (2x - 3)⁵ is,
⇒ (2x)⁵ – 15(2x)⁴ + 90(2x)³ – 270(2x)² + 405(2x) – 243

y= mx +C
So m, that is the slope of line will be 2.
Now the slope of required line will also be 2.
We can write
(y- (- 1)) =2 (x-(-4))
y+1 = 2(x+4)
y=2x+7
What is the slope of the line that passes through the points (10, 3) and (2, 3) ?
Answers
(3-3)/(2-10) = 0/-8 = 0
The slope is 0
Work Shown:
Use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (3-3)/(2-10)
m = 0/(-8)
m = 0
The slope of any horizontal line is always zero due to the fact all y coordinates on this line are the same. When we pick two points from the line, the same y coordinates subtract to 0. We can have 0 in the numerator, but not in the denominator.
As the slope formula shows, we basically subtract the y coordinates together, and do the same for the x coordinates as well in the same order. Then we divide the differences.

4x – 2y = 2
x = y + 4
Answers
Answer:
y = -7 and x = -3
Step-by-step explanation:
Substitute x for y + 4 in the first equation and solve for y
4(y+4) - 2y = 2
4y + 16 - 2y = 2
16 + 2y = 2
2y = -14
y = -7
Then in order to find x, substitute y for -7 in the second equation
x = -7 + 4
x = -3
Answer:
x= -3, y= -7
Step-by-step explanation:
substitute x=y+4 in the first equation
4 (y+4) -2y =2 distribute
4y+16-2y=2 subtract both sides by 16
4y-2y=2-16 combine like terms
2y= -14 divide both sides by 2
y=-7
x=y+4 substitute y=-7
x= -7+4
x= -3

Answers
Answer:
Step-by-step explanation:
Political parties are organized groups of people with similar ideas or ideology about the function and scope of government, with shared policy goals that work together to elect individuals to political office, to create and implement policies, to further an agenda, and to gain control of the government and the policy-making process. Parties gain control over the government by winning elections with candidates they officially sponsor or nominate for positions in government. Political parties nominate candidates to run many levels of government including the national level, Congress, and the presidency; but, they nominate for state and local levels as well. They also coordinate political campaigns and mobilize voters.
Political parties are points of access/linkage institutions available to the public, though they are not themselves government institutions. Neither interest groups nor political parties are directly mentioned in the U.S. Constitution. Where interest groups often work indirectly to influence our leaders, political parties are organizations that try to directly influence public policy through nominating and officially sponsoring members who seek to win and hold public office. This is a key difference. Interest groups do not officially nominate or nominate candidates for public office, although they may support them politically and even contribute dollars to their campaign.
Parties accomplish this by identifying and aligning sets of issues that are important to voters in the hopes of gaining support during elections. In this respect, parties provide choices to the electorate, something they are doing that is in sharp contrast to their opposition. These positions on these critical issues are often presented in campaign documents or political advertising. During a national presidential campaign, they also frequently reflect the party platform, which is adopted at each party’s presidential nominating convention every four years.
If successful, a party can create a large enough electoral coalition to gain control of the government. Once in power, the party is much more likely to be able to deliver, to its voters, the policy preferences they choose by electing its partisans to the government.Political parties organize political campaigns to win public office for those they nominate.

The domain of 0 ≤ x ≤ 6 is x ∈ [0, 1, 2, 3, 4, 5, 6], and the range of the 0 ≤ y ≤ 6 is y ∈ [0, 1, 2, 3, 4, 5, 6].
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
0 ≤ y ≤ 72
The range will be y ∈ [0, 72]
0 ≤ x ≤ 72
The domain will be x ∈ [0, 72]
0 ≤ x ≤ 6
The domain will be x ∈ [0, 1, 2, 3, 4, 5, 6]
0 ≤ y ≤ 6
The range will be y ∈ [0, 1, 2, 3, 4, 5, 6]
Thus, the domain of 0 ≤ x ≤ 6 is x ∈ [0, 1, 2, 3, 4, 5, 6], and the range of the 0 ≤ y ≤ 6 is y ∈ [0, 1, 2, 3, 4, 5, 6].
