Answer:
7.81
Step-by-step explanation:
Pythagorean theorem
[tex]\sqrt{6^{2} +5^{2} }[/tex]
[tex]\sqrt{61}[/tex]= 7.81
c = 7.81
Law of Cosines
[tex]c=\sqrt{b^{2} +a^{2}-2ba*cos(C) }[/tex]
[tex]c=\sqrt{6^{2}+5^{2}-((2*6*5)*cos(90)) }[/tex]
c = 7.81
16. Rihanna is the founder and CEO of Fenty Beauty on the release day of her new product,
Flyliner Longwear Liquid Eyeliner, she sold 400 eyeliners
and averaged 50 eyeliner sales
per day after that.
Which equation models the number of Flyliner Eyeliners, f, did Rihanna sell after d days.
A. f = 400 + 50d
B. f = 50 + 400d
C. d = 50 + 400f
D. d = 400 + 50f
Answer:
A. f = 400 + 50d
Step-by-step explanation:
First, let's understand each quantity/variable.
d: The variable, d, represents the number of days.f: f represents the total amount of eyeliners sold after each day.400 eyelines sold: This means that Rihanna sold 400 eyeliners on the first day of the release of her liquid eyeliner. This is known as the y-intercept.50 eyeliner sales per day: This means that after her first day, Rihanna sold 50 eyeliners each day. This can be represented as 50d.Now that we understand these variables, we can conclude that the equation would be A. f = 400 + 50d because to find the total, we have to add the 400 eyeliners sold at the beginning to the 50 eyeliner sales per day.
Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer: C
Step-by-step explanation:
Answer:
B. SSA
Step-by-step explanation:
Since segments JK and RQ are parallel, they are similar by both extending at the same angle and both segments formed by the parallel lines being proportional segments.Since the lengths of segments KZ and ZR are given, they are similar because they are proportional.Since vertical angles are always equivalent by the Vertical Angles Theorem, angles JZK and RZQ are congruent.Because we have 2 sides with a non-included (not in-between the two sides) angle, the triangles are similar by SSA Similarity.

Is this angle supplementary or congruent? Please help.
Answer:
supplementary
Step-by-step explanation:
we have,
3x+15+2x=180
=> 5x +15 = 180
=> 5x = 180-15
=> 5x = 165
=> x = 165/5
=> x= 33
so, 3x+15 = 3*33+15
=> 99+15
=>114
2x = 2*33
=> 99
now we can check if these angles are supplementary
114 + 99 = 180
so, they are supplementary

Renee is walking to a store that is 2. 5 kilometers from her house. After 700 meters, she stops at her friend’s house
What is the distance that Renee will walk from her friend’s house to the store?
Because she stopped at her friend's house on the way to the store, it can be seen that there is no detour. This means that the distance between her friend's house to the store is a subtraction problem
2.5 km - 700m=2500m-700m=1800m or 1.8km

Which of the following is not a characteristic of a point?
A. Flat surface
B. Named using a capital letter
C. No depth or width
D. Undefined term
Answer:
D. Undefined term
Step-by-step explanation:
Points are flat surfaces, named using a capital letter, and have no depth or width because they are on a FLAT plane. Just like lines are named "line A", are on a flat surface, and have no depth or width, points also share these characteristics because they are all on a plane. However, a point is not an undefined term, it is a defined term.
A point is a geometric feature used for the definition of geometric objects
The option which is not a characteristic of a point is option A:
A. Flat surface
The reason for the above selection is as follows:
A point in Euclidean geometry is a concept that defines an exact spatial location
The characteristics of a point are:
A point only represents position, it has no dimensions; It does not have a thickness, width, or lengthThe explanation given of a point is made by use of descriptions or examples and therefore, a point is considered an undefined termA point can be denoted or named using capital letters and represented using dotsA flat surface is defined by three noncolinear points
Therefore;
The given option which is not a characteristic of a point is therefore option A. Flat surface

please help! Find the value of the convergent series:
Answer:
2.25
Step-by-step explanation:
Notice how the common ratio is -1/3, which means the series passes part 1 of the convergence test because -1/3 is in between -1 and 1.
We can also represent this as a summation series of
[tex]Σ3( - \frac{1}{3} ) {}^{n - 1} [/tex]
Since we can represent this a summation series, we can use that convergent value is equal to
[tex] \frac{a _{1} }{1 - r} [/tex]
where a1 is initial term and r is common ratio.
R is -1/3
A1 is 3.
[tex] \frac{3}{1 - \frac{ - 1}{3} } = \frac{3}{ \frac{4}{3} } = 2.25[/tex]
So the answer is 2.25

Answer:
1) 21
2a) -23/30
2b) 6/55
Step-by-step explanation:
1) 3(x + 2) + 5x + 7
expand the brackets:
= 3x + 6 + 5x + 7
collect like terms:
= 8x + 13
when x = 1, (just substitute 1 for x)
8(1) + 13
= 8 + 13
= 21
2a)
-9/10 + 2/15
put both fractions on the same denominator (often we can just multiply each denominator by the other one):
so -9/10 * 15/15
= -135/150
and 2/15 * 10/10
= 20/150
now they're both on the same denominator and we can add the numerators:
-135 + 20 = -115
so our answer is:
-115/150
which we can simplify to:
-23/30
2b)
3/11*2/5
Multiplying fractions is very simple, as it doesn't require to have the same denominators. We can just multiply the numerators by each other and same for the denominators:
3*2 = 6
11*5 = 55
therefore, our answer is:
6/55

the expression 53.7124×103 as a single number
Answer:
53712.4
Step-by-step explanation:
[tex]53.7124 * 10^{3}[/tex] This is the scientific notation, and since we do not have a negative exponent, we can assume that the decimal is going to move to the right, because when it's negative, the decimal will move to the left, making a smaller number.
So, when we move the decimal 3 times to the right, we find it sitting at 53712.4
