How many times does the digit one appear from 101 to 200
Answer:
Step-by-step explanation:
Let's get the answer first and then we can discuss how it is done. The answer is 119.
There is a problem. The question does not state whether or not 101 is included. If it is 119 is correct. If the question is between 101 and 200 then the answer will be 117.
How was it done? A programming language was used. So it counted by brute force.
From 101 to 120 we get
101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120
32 Certainly there must be a quicker way
101 = 2
102 to 109 = 1 * 8 = 8
110 to 119 = 10*2 = 20
111 has an extra 1 = 1
120 has 1
Total 32
From here it gets a bit easier.
121 2
122 - 129 8
total 10
130 1
131 2
132 - 139 8
total 11
140 to 149 11
150 to 159 11
160 to 169 11
170 to 179 11
180 to 189 11
190 to 199 11
total 7 * 11 + 32 + 10 = 119
What is the quotient of 7-1/7-2?
Answer:
7
Step-by-step explanation:
\The graph for the equation y = negative x + 2 is shown below. On a coordinate plane, a line with positive slope goes through (0, 2) and (2, 0). If another equation is graphed so that the system has an infinite number of solutions, which equation could that be? y = negative 2 (x minus 1) y = negative (x + 2) y = negative one-fourth (4 x minus 8) y = negative one-half (x + 4)
An infinite number of solutions is generated with a multiple of the first function, hence, the correct option is:
[tex]y = -\frac{1}{4}(4x - 8)[/tex]
The graph given is:
[tex]y = -x + 2[/tex]
When two equations are multiple, the system involving these two equations has infinite solutions.
Among the options, the multiple of the original function is:
[tex]y = -\frac{1}{4}(4x - 8)[/tex]
[tex]y = -x + 2[/tex]
Hence, [tex]y = -\frac{1}{4}(4x - 8)[/tex] is the correct option.

[tex]sin(\theta)=\frac{40}{41} \\cos(\theta)=\frac{9}{41} \\tan(\theta)=\frac{40}{9}\\csc(\theta)=\frac{41}{40} \\sec(\theta)=\frac{41}{9} \\cot(\theta)=\frac{9}{40}[/tex]
Step-by-step explanation:
Notice we can use the Pythagorean theorem to find the measure of the unknown side via:
[tex]123^2=120^2+x^2\\x^2=729\\x=\sqrt{729} \\x=27[/tex]
and now, knowing all the sides, we can find all te trigonometric functions of the angle [tex]\theta[/tex]:
[tex]sin(\theta)=\frac{opp}{hyp} = \frac{120}{123} =\frac{40}{41} \\cos(\theta)=\frac{adj}{hyp} = \frac{27}{123} =\frac{9}{41} \\tan(\theta)=\frac{opp}{adj} = \frac{120}{27} =\frac{40}{9}\\csc(\theta)=\frac{41}{40} \\sec(\theta)=\frac{41}{9} \\cot(\theta)=\frac{9}{40}[/tex]
Can someone help me find the GCF of 35 and 63 please show your work thank you
The first step to find the gcf of 35 and 63 is to list the factors of each number. The factors of 35 are 1, 5, 7 and 35. The factors of 63 are 1, 3, 7, 9, 21 and 63. So, the Greatest Common Factor for these numbers is 7 because it divides all them without a remainder.
To sum up, the gcf of 35 and 63 is 7. In common notation: gcf (35,63) = 7.

Suraj has $15.00 to spend. He decided to buy a shirt for $9.95 and spend the rest on candy bars. If each candy bar costs $1.50, how many candy bars can Suraj buy?
Answer:3
Step-by-step explanation: i think
Answer:
He can by 3 candy bars.
Step-by-step explanation:
15.00-9.95=5.05
5.05-1.50=3.55
3.55-1.50=2.05
2.05-1.50=0.55 cents
Suppose you have 6 pairs of socks in your sock drawer. It is still dark out in the morning when you get dressed, so you just pull socks out of the drawer at random, one at a time, until you have removed two matching socks. What is the probability that you pull out exactly 5 socks from your sock drawer in the morning?
Answer:
8/33 = 0.242
Step-by-step explanation:
There are 12 socks to begin with and one is taken;
The second is picked from the remaining 11 and will either match the first or not;
The probability of matching is 1/11 and 10/11 for not matching;
If the sock matches, no further sock is taken;
If the socks don't match, a 3rd sock is taken;
The 3rd sock is taken from the remaining 10, 1 of which will match with the first sock and another which will match the second;
Therefore, the probability of taking a matching sock on the third pick will by 2/10 or 1/5 and the probability it will not match either of the first two is 8/10 or 4/5;
Once again, if the sock matches either of those previously taken, no further sock is taken;
If the socks don't match, a 4th sock is taken;
Now, there are 9 socks remaining in the drawer;
Picking is repeated;
The process is logical;
The attached picture shows a tree diagram representing this information in an easily digestible way and makes it easy to work out the desired probability;
With tree, diagrams, you just multiply across until you get to your desired outcome;
In this case, we are finding the probability of picking 5 socks exactly;
Each process splitting represents the picking of a sock;
The probability will be:
10/11 × 8/10 × 6/9 × 4/8 = 8/33 = 0.242...

Answer:
Initial temperature = 20° C
Temperature after 18 minutes = 4° C
Step-by-step explanation:
Function representing the relation in the temperature of the soda and time has been given as,
T(x) = [tex]-8+28e^{-0.045x}[/tex]
Here x = number of minutes since the can was placed in the cooler
For initial temperature of the soda,
x = 0,
T(0) = [tex]-8+28e^{(28\times 0)}[/tex]
= -8 + 28(1)
= 20° C
For the temperature after 18 minutes,
x = 18,
T(18) = [tex]-8+28.e^{-0.045\times 18}[/tex]
= [tex]-8+28.e^{(-0.81)}[/tex]
= [tex]-8+12.456[/tex]
= 4.456 C
≈ 4° C

Which congruence theorem can be used to prove ABDA - ABDC?
Answer:
SAS(SIDE ANGLE SIDE)
Step-by-step explanation
AB side in ABDA = AB side in ABDC
ABD angle in ABDA= ABD angle in ABDC
BD side in ABDA = BD side in ABDC
The congruence theorem can be used to prove ABDA - ABDC is SAS.
What is Congruence of Triangles?Congruence of triangles: Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure. These triangles can be slides, rotated, flipped and turned to be looked identical. If repositioned, they coincide with each other. The symbol of congruence is’ ≅’.
According to the questions,
AB side in ABDA = AB side in ABDC
ABD angle in ABDA= ABD angle in ABDC
BD side in ABDA = BD side in ABD
Thus SAS is applied.
Hence SAS(Side Angle Side) is the required answer.
