(5.-10). (-5, 4)
Answer:
2 sqrt 74
Step-by-step explanation:
d^2 = ( x1-x2)^2 + (y1-y2)^2
d^2 = ( 5 - -5 )^2 + ( -10 -4)^2
= 100 + 196
d^2 = 296

a is 25% of b
b is 30% of c.
Write the ratio a:b:c
Give your ratio in its simplest form.
Answer:
40a : 10b : 3c
Step-by-step explanation:
We can write this information more mathematically by saying:
[tex]a = \frac{1}{4} b[/tex]
[tex]b= \frac{3}{10} c[/tex]
This can be written as ratios as well by making them all integers so:
4a : b
10b : 3c
By making the b's in both equations the same, we can link all the ratios together so:
40a : 10b
10b : 3c
So,
40a : 10b : 3c

O Two
O None
One
O Infinitely many
Answer:
one
Step-by-step explanation:
3x + 6 = -1 - 3 + 4x
Combine like terms
3x+6 = -4 +4x
Subtract 3x from each side
3x+6-3x = -4+4x-3x
6 = -4+x
Add 4 to each side
4+6 = -4+x+4

Answer:
C. AC~= DF, FB~=CB
Step-by-step explanation:
In order use HL theorem you have to have two right triangles, which it's marked that you do. HL stands for Hypotenuse-Leg. So in order to use Hypotenuse-Leg you have to know that the hypotenuses are congruent on the two triangles and also a leg is the same on the two triangles. AC and DF are the two hypotenuse. And FB and CB are legs. You need those two congruent segment pairs in order to use HL theorem.
FIND THE EXACT AREA OF THE SHADED PLEASE HELP ILL GIVE BRAINLIESTTTT
well, if we take the whole area of the circle, including the trapezoid in it, and then we get the area of the trapezoid and subtract it from that of the circle's, what's leftover is what we did not subtract, namely the shaded area. Let's notice the circle has a diameter of 20, thus a radius of half that, or 10.

A particular extension cord can support up to 8 amps. Martino has an iron whose label states 720 watts, and he wonders if the iron can be plugged into the extension cord. If watts are converted to amps by dividing by 144, how many amps does the iron use?
Answer:
Step-by-step explanation:
Remark
To convert watts to amps, divide the watts by the amps
Givens
720 watts
8 amps (maximum safety of extension chord)
144 conversion factor
Solution
Amps = 720 watts / 144
Amps = 5
Answer
The iron uses 5 amps of current.
The extension chord is safe to use since 5 is less than 8

Answer:
m<6 = 119°
Step-by-step explanation:
Two lines are parallel with each along a line.
m<4 and m<6 are supplementary angles which both angles add up to 180°.
m<4 + m<6 = 180°
61° + m<6 = 180°
m<6 = 180° - 61°
m<6 = 119°

Answer:
x = 6
Step-by-step explanation:
Interior angles of a triangle sum to 180°
⇒ (8x + 2)° + 70° + 60° = 180°
⇒ 8x + 132° = 180°
Subtract 132° from both sides:
⇒ 8x + 132° - 132° = 180° - 132°
⇒ 8x = 48°
Divide both sides by 8:
⇒ 8x ÷ 8 = 48° ÷ 8
⇒ x = 6
Therefore, the value of x is 6.

A:may lead to biased results.
B:is not important.
C:should always include people you can access conveniently.
D:will not change the results of the data.
Answer:
When selecting a sample for a survey, the way you choose your sample: A) may lead to biased results.
Step-by-step explanation:
The way you choose your sample matters a lot in order to help limit the bias in sampling data.
There are four types of random samples: simple, stratified, cluster, and systematic.
There are two types of non-random samples: voluntary response and convenience.
You always want to have a random sample in order to have accurate, non-biased results. Therefore, A) May lead to biased results is the best answer.

If a₁ = 2 and an = an-1 +5 then find the value of a5. for recursive sequence
Answer:
[tex]a_{5} = 22[/tex].
Step-by-step explanation:
In this recursive sequence, the value of the first term [tex]a_{1} = 2[/tex] is stated explicitly. The value of every other term of this sequence is given as an expression of the previous term.
For example, the value of the term [tex]a_{2}[/tex] ([tex]n = 2[/tex]) is given in terms of the value of [tex]a_{1}[/tex]:
[tex]\begin{aligned}a_{2} &= a_{(2 - 1)} + 5 \\ &= a_{1} + 5\end{aligned}[/tex].
Likewise, the value of [tex]a_{3}[/tex] ([tex]n = 3[/tex]) would be:
[tex]\begin{aligned}a_{3} &= a_{(3 - 1)} + 5 \\ &= a_{2} + 5 \\ &= (a_{(2-1)}+5) + 5 \\ &= (a_{1} + 5) + 5 \\ &= a_{1} + 2 \times 5 \\ &= a_{1} + (3 - 1) \times 5\end{aligned}[/tex].
In general, the value of [tex]a_{n}[/tex] (for integer [tex]n \ge 1[/tex]) would be:
[tex]\begin{aligned} a_{n} &= a_{1} + (n - 1) \times 5 \\ &= 2 + (n - 1) \times 5\end{aligned}[/tex].
Therefore, the value of [tex]a_{5}[/tex] ([tex]n = 5[/tex]) would be:
[tex]\begin{aligned}a_{5} &= a_{1} + (5 - 1) \times 5 \\ &= 2 + (5 - 1) \times 5 \\ &= 22\end{aligned}[/tex].

How many different strings can be made from the letters in ORONO using some or all of the letters? (15 pts.)
The number of different strings that can be made from the letters in ORONO using some or all of the letters is 63
What is the number of permutations in which n things can be arranged such that some groups are identical?Suppose there are n items.
Suppose we have
[tex]i_1, i_2, ..., i_k[/tex]
sized groups of identical items.
Then the permutations of their arrangements is given as
[tex]\dfrac{n!}{i_1! \times i_2! \times ... \times i_k!}[/tex]
We're given the word ORONO.
Case 1: One letter string:3 ways: O, R, or N
Case 2: Two letter string:Subcase: Consists O:
5 ways: OR, RO, ON, NO, OO
Subcase: Doesn't consist O:
2 way: RN, NR
Total permutation under this case = 5+2 = 7
Case 3: Three letter string:Subcase: Consists 3 'O':
1 way: OOO
Subcase: Consists 2 'O':
6 ways: OOR, ROO, ORO, OON, NOO, ONO
Subcase: Consists 1 'O':
6 ways: ORN, ONR, RNO, RON, NOR, NRO (or that there are 3 distinct letters to be arranged, which can be done in 3! = 6 ways)
Subcase: Doesn't consist O:
0 ways as only R and N cannot form three letter string.
Total permutation under this case = 1+6+6= 13
Case 4: 4 letter string:Subcase: Consists 3 'O':
So, we've got {O,O,O,R,N}
3 'O's are mandatory, so fourth letter is either R or N:
O, O, O, R can arrange themselves in : [tex]4!/3! = 4 \: \rm ways[/tex] (as total 4 words but 3 are identical)
Similarly, O, O, O, N can arrange themselves in 4 ways,
So when 4 letter string from ORONO consists of 3 'O's, then total 4+4=8 distinct strings can be made.
Subcase: Consists 2 'O':
So, we've got {O,O,R,N}
The total permuations of these 4 letters, of which 2 are identital is:
[tex]\dfrac{4!}{2!} = 12[/tex]
Subcase: Consists 1 'O':
0 ways: Single 'O' and one-one R and N cannot form four letter string.
Subcase: Doesn't consist O:
0 ways as only R and N cannot form four letter string.
Total permutation under this case = 8+12 = 20
Case 5: Five lettered string:All 5 letters of ORONO would be used.
There are 3 identical objects, so total number of their permutation is:
5!/3! = 20
Thus, from all these cases, we conclude that:
Total permutations of string letters using some or all letters of ORONO is:
3+7+13+20+20 = 63
Thus, the number of different strings that can be made from the letters in ORONO using some or all of the letters is 63

How many times will you have to fill up the cylindrical beaker before the tank is full? Round to the nearest tenth.
0.9947≅1 times you have to fill up the cylindrical beaker before the tank is full.
What is volume?Volume is defined as the space occupied by any body in the three-Dimenions. All three parameters are required for the volume like length,width and hieght of cube or cubied.
here we have a beaker of cylindrical shape the volume of the shape will be calculated as:

Let p and h represent pay and hours worked respectively,
p = kh
k = p/h = 148.5/18 = 8.25
p= 8.25h
90.75 = 8.25h

Consider the problem: After charging for 1/3 of an hour, a phone is at 2/5 of its full power. How long will it take the phone to charge completely?
Base on the given ratio, it will take the phone 5/6 hours to charge completely
How to determine the time to charge completely?The given parameter can be represented as:
Ratio = Time : Proportion
So, we have:
Ratio = 1/3 : 2/5
To charge fully, we have:
Time : 1 = 1/3 : 2/5
Express as fraction
Time/1 = 1/3/ 2/5
Evaluate
Time = 5/6

Circumference = 2914 Area Пr2
A. 1,607,68 cm2
B. 200.96 cm?
C. 803.84 cm?
D. 50.24 cm
Answer:
803.84, or C.
Step-by-step explanation:
If we know the circumference then we can use that to find the radius!
-
(π =pi)
Area of a circle formula: π · r^2
-
Let us plug in the circumference into the formula (not the area formula, the circumference one!)
c=2πr
100.48=2πr - 2*3.14 =6.28
100.48=6.28r
divide both sides by 6.28!
r= 16
Now, we plug that in the area formula.
π · r^2
3.14 * 16^2
3.14 * 256 =
803.84
