I'm thinking of a number.My number is a whole number.My number is larger than 100.My number mod 17 = 9.My number is smaller than 200.What could be number be? (Give one possible answer. There are several correct answers.)
Answers
Answer:
the number could be any of these numbers (111, 128, 145, 162, 179, 196)
Step-by-step explanation:
From the given information, let the number that I'm thinking of to be p
p is > 100
p is < 200
and p = 9 (mod 17)
This implies that 17 ÷ p -9
p - 9 = 17q
here;
q is an integer
p = 9 + 17q
However,
100 < p < 200
= 100 < 9+17q < 200
= 100 - 9 < 17q < 200 -9
= 91 < 17q < 191
Dividing both sides by 17; we have:
= [tex]\dfrac{91}{17}< q < \dfrac{191}{17}[/tex]
= 5.45 < q < 11.24
thus the possible values of q are between 6,7,8,9,10 and 11
The possible values of p can now be:
p = 9 +17(q)
p = 9+17(6), 9+17(7), 9+17(8), 9+17(9), 9+17(10), 9+17(11)
p = 111, 128, 145, 162, 179, 196
Therefore, the number could be any of these numbers (111, 128, 145, 162, 179, 196)

The base of 14-foot ladder is 6 feet from a building. If the ladder reaches the flat roof, how tall is the building?
Answers
Answer:
Approximatly 12.65
Step-by-step explanation:
You would use the pythagorean Theoram for this.
[tex]a^{2}+6^{2}=14^{2}[/tex]
[tex]a^{2}+36=196[/tex]
Subtract 36 from both sides:
[tex]a^{2}=160[/tex]
Square 160 to remove the exponent on "a":
[tex]a=\sqrt{160}[/tex]
[tex]a≈ 12.65[/tex]
If the ladder reaches the flat roof, then the height of the building will be 12.65 feet.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The base of 14 feet ladder is 6 feet from a building. Then the length of the hypotenuse is 14 feet and the base is 6 feet. Then the height of the building will be given by the Pythagoras theorem.
If the ladder reaches the flat roof, then the height of the building will be
H² = P² + B²
14² = P² + 6²
196 = P² + 36
P² = 196 - 36
P² = 160
P = 12.65 feet
If the ladder reaches the flat roof, then the height of the building will be 12.65 feet.

Sandy and Steve share some prize money in the ratio 4:3. The prize money totaled $1400 How much
does Sandy receive ?
Answers
Answer:
Sandy will receive $800
Steve will receive $600
Step-by-step explanation:
Sandy : Steve = 4 : 3
Sandy = 4
Steve = 3
Total ratio = 4 + 3 = 7
Total prize money = $1400
How much does Sandy receive ?
Sandy's share = Sandy's ratio / total ratio × Total prize money
= 4 / 7 × 1400
= 4 × 200
= $800
Sandy will receive $800 out of $1400
Steve's share = Steve's ratio / total ratio × Total prize money
= 3 / 7 × $1400
= 3 × $200
= $600
Steve will receive $600 out of $1400
Check:
Sandy's share + Steve's share
= $800 + $600
= $1400

3. While trick or treating with his buddies, Albert noticed he received 7 Kit Kat bars after
visiting 10 houses. If they plan on visiting 65 houses, how many Kit Kat bars might he receive
by the end of the night?
Answers
So all you have to do in this problem is multiply the amount with 6 and you can get the amount for 60 houses: 42
And then you can divide half of 7 to get the amount for 5 houses. However, we cannot use decimals in this problem. So round the amount: 3.5=4
So approximately Albert should get somewhere near 46 kk bars.
That’s a Meanie Genie. On an archeological dig near the highlands of Tibet, Alley discovered an ancient oil lamp. Just for laughs she rubbed the lamp. She quickly stopped laughing when a huge puff of magenta smoke spouted from the lamp and an ornery genie Murray appeared. Murray gave her two balance scales and nine identical stones as per her three wishes. Alley may use each of the scales exactly once. Choose a possible way for Alley to select the slightly heavier stone containing Ramanujan from among the nine identical-looking stones.
Answers
Answer:
Step-by-step explanation:
Arrange the stones into 3groups of 3and place one group on one side of the first balance scale and another group on the other side.
If both sides weigh the same, then she knows that the (heavier) jewel must be in the third group of three. However, if one side is heavier than the other, then she knows that the jewel is one of the three that weighed more. In either case, after only one weighing, Alley is able to identify a group of only three stones among which is the Rama Nujan.
Then take 2 of the 3 stones and place one on each side of the second scale. If one weighs more than the other, then she knows that this stone is the one containing the jewel. If they both weigh the same, then she knows that the third stone must contain the jewel.

Find an equation for the surface obtained by rotating the line x = 6y about the x-axis.
Answers
Answer:
[tex]\frac{x^2}{36}=y^2+z^2[/tex]
Step-by-step explanation:
If we loo at the xy plane and consider the point (6y, y, 0), it looks like a circular path that is a cone as the curve is rotated about the x axis. The equation of the cone has the form:
[tex]\frac{x^2}{c^2}=\frac{y^2}{a^2}+\frac{z^2}{b^2}[/tex]
Given that x = 6y, to make the equation to be in the form as seen above, we square x = 6y, hence:
x² = (6y)²
x² = 36y²
The path parallel to yz axis are circles, so the equation should be as that of a circle. We need to add 36z², hence:
x² = 36y² + 36z²
[tex]\frac{x^2}{36}=y^2+z^2[/tex]
[tex](\frac{x}{6})^2=y^2+z^2[/tex]
This equation is that of a circle with radius of r = y = x/6, the resulting surface is that of a cone

If m<TUV = (9x + 1), m<TUW = (7x-9), and m<WUV = (5x - 11), find the value of x.
Answers
Answer: x = 7
Step-by-step explanation:
Suppose ray UW divides ∠TUV into two angles ∠ TUW and ∠ WUV.
Then, m∠TUV = m∠ TUW + m ∠ WUV (i)
Given, m∠TUV = (9x + 1) , m∠ TUW = (7x-9) and m ∠ WUV = (5x - 11)
Substitute these values in (i), we get
[tex]9x+1=7x-9+5x-11\\\\\Rightarrow\ 9x+1= 7x+5x-9-11\\\\\Rightarrow\ 9x+1=12x-20\\\\\Rightarrow\ 12x-9x= 1+20\\\\\Rightarrow\ 3x= 21\\\\\Rightarrow\ x=\dfrac{21}{3}\\\\\Rightarrow\ x=7[/tex]

Answer:
What is the question? Is this a true or false question ?
Step-by-step explanation:
The percentage of surveys done if, A political scientist surveys 38 of the current 153 representatives in a state's congress is 25%.
What is percentage?As it is clear from the term, percent means measuring anything per hundred. For example, you get marks per 100 marks, so you get the percentage.
Given:
The number of surveys done = 38,
The representatives in a state's congress = 153,
Calculate the percentage as shown below,
Percentage of survey = The number of surveys done / total representative × 100,
Percentage of survey = 38 / 153 ×100
Percentage of survey = 0.25 × 100
Percentage of survey = 25 %

Answers
Answer:
a. No solution, parallel lines.
b. One solution.
Step-by-step explanation:
Given the system of equations:
a. [tex]2x-4y=12[/tex]
[tex]-3x+6y=-15[/tex]
b. [tex]2x-4y=12[/tex]
[tex]-5x+3y=10[/tex]
To give a geometric description of the given system of equations.
The geometric description of a system of equations in 2 variables mean the system of equations will represent the number of lines equal to the number of equations in the system given.
i.e.
Number of planes = Number of variables
Number of lines = Number of equations in the system.
Here, we are given 2 variables and 2 equation in each system.
So, they can be represented in the xy-coordinates plane.
And the number of solutions to the system depends on the following condition.
Let the system of equations be:
[tex]A_1x+B_1y+C_1=0\\A_2x+B_2y+C_2=0[/tex]
1. One solution:
There will be one solution to the system of equations, If we have:
[tex]\dfrac{A_1}{A_2}\neq\dfrac{B_1}{B_2}[/tex]
2. Infinitely Many Solutions: (Identical lines in the system)
[tex]\dfrac{A_1}{A_2}=\dfrac{B_1}{B_2}= \dfrac{C_1}{C_2}[/tex]
3. No Solution:(Parallel lines)
[tex]\dfrac{A_1}{A_2}=\dfrac{B_1}{B_2}\neq\dfrac{C_1}{C_2}[/tex]
Now, let us discuss the system of equations one by one:
a. [tex]2x-4y=12[/tex] OR [tex]2x-4y-12=0[/tex]
[tex]-3x+6y=-15[/tex] OR [tex]-3x+6y+15=0[/tex]
[tex]A_1 = 2, B_1 = -4, C_1 = -12\\A_2 = -3, B_2 = 6, C_2= 15[/tex]
Here, the ratio:
[tex]\dfrac{A_1}{A_2}=\dfrac{B_1}{B_2} = -\dfrac{2}{3}\\\dfrac{C_1}{C_2} = -\dfrac{4}{5}[/tex]
[tex]\dfrac{A_1}{A_2}=\dfrac{B_1}{B_2}\neq\dfrac{C_1}{C_2}[/tex]
Therefore, no solution i.e. parallel lines.
b. [tex]2x-4y=12[/tex] OR [tex]2x-4y-12=0[/tex]
[tex]-5x+3y=10[/tex] OR [tex]-5x+3y-10=0[/tex]
[tex]A_1 = 2, B_1 = -4, C_1 = -12\\A_2 = -5, B_2 = 3, C_2 = -10[/tex]
[tex]\dfrac{A_1}{A_2}= -\dfrac{2}{5}\\\dfrac{B_1}{B_2} = -\dfrac{4}{3}\\\dfrac{C_1}{C_2} = -\dfrac{6}{5}[/tex]
[tex]\dfrac{A_1}{A_2}\neq\dfrac{B_1}{B_2}[/tex]
So, one solution.
