what is the reciprocal of 19
Answer:
1/19
Step-by-step explanation:
In order to find the reciprocal of a number, we need to flop it over.
"Flopping over" is not the same as "changing the sign of the number"
So what does "flopping over" actually mean?
Consult the following formula:-
[tex]\sf{The~reciprocal~of~a~is\mapsto\frac{1}{a} }[/tex]
According to the formula,
[tex]\sf{The~reciprocal~of~19~is~\frac{1}{19}}[/tex]

cuales son los angulos de 125
[tex] [/tex]
Answer:
Ángulo de 125 grados Cómo se llama
Este ángulo es obtuso porque 120 es un número mayor que 90 y menor que 180. Es decir, la amplitud de este ángulo mide entre los 90º y los 180º: 90º < 120º < 180º.

HELP ME PLEASEEEEE THIS IS SO HARD
Answer:
4. Given
6. Definition of verticle angles
7. Algebra/part-whole-postulate/sum of interior angles in a triangle/CPTCTC (Corresponding parts of congruent triangles are congruent)
Step-by-step explanation:
number 4 is just...given because it shows that they're both right angles
6, it's literally the definition of verticle angles
7, since we know that angle TQU and angle RSU are congruent and angle QUT and SUR are congruent, if we subtract those from 180, that means those two angles also have to be congruent
Also, the two triangles are congruent by LA or ASA, so CPCTC would also work
Part-whole-postulate, same reasoning as algebra.
Sum of interior angles in a triangle, same as algebra.
Hope this helped, let me know if you have any questions.
What is the value of x in the solution to this system of equations?
X-y=6
y=2x-5
A 1
B-1
C3
D-7
Answer:
B) -1
The 'x' value =-1 and y =-7
The solution of the given system of equations
(-1,-7)
Step-by-step explanation:
Step(i)
Given that the system of equations
x-y = 6 ..(i)
y = 2x -5 ..(ii)
By using substitution method,
substitute y=2x-5 in equation (i) , we get
x -(2x-5) =6
x -2x+5 =6
-x = 6-5
-x =1
x=-1
Step(ii):-
Put x=-1 in equation (ii) , we get
y = 2(-1) -5 = -2-5 =-7
The solution of the given system of equations
(-1,-7)

A factory produce bicycles at a rate of 110+0.5t^2-0.9t bicycles per week (t in weeks)
how many bicycles were produced from 8 to 2
Answer:
221
Step-by-step explanation:
Day 8 is the first day of the second week.
Day 21 is the last day of week 3.
We need to know the n umber of bicycles made from t = 1 to t = 3
The function is b(t) = 110 + 0.5t^2 - 0.9t, where t is in weeks.
We need to integrate the function with the limits of 1 to 3.
[tex] \int_{1}^{3} (110 + 0.5t^2 - 0.9t) dt [/tex]
[tex] \int_{1}^{3} (110 + \dfrac{t^2}{2} - \dfrac{9t}{10}) dt [/tex]
[tex]= 110t + \dfrac{t^3}{6} - \dfrac{9t^2}{20} \Biggr|_{1}^{3}[/tex]
[tex] = 330.45 - 109.72 [/tex]
[tex] = 220.7333 [/tex]

Mallory bought pizza and soda for her End of Summer party. If she spent $12.57 on the
sodas and $10.95 for each pizza, how many pizzas did she buy if she spent $89.22?
Which equation models this scenario?
12.57 + 10.95 = 89.22
10.95x + 12.57 =
89.22
12.57x + 10.95 =
89.22
89.22x - 10.95 = 12.57
Answer:
10.95x + 12.57 = 89.22

Kiran and Clare like to race each other home from school. They run at the same speed, but Kiran's house is slightly closer to school than Clare's house. On a graph, their distance from their homes in meters is a function of the time from when they begin the race in seconds.
As you read the graphs left to right, would the lines go up or down?
What is different about the lines representing Kiran's run and Clare's run?
What is the same about the lines representing Kiran's run and Clare's run?
Answer:
1. Down.
2. Clare's line would be higher because she begun further away from her house.
3. The lines would have the same slope since they are going the same speed.

Step 1: Define
3 - 6(z - 2)
z = -2
Step 2: Evaluate
Substitute in z: 3 - 6(-2 - 2)(Parenthesis) Subtract: 3 - 6(-4)Multiply: 3 + 24Add: 27By substituting value of z = - 2 in 3 - 6(z - 2), we get :
[tex] \tt : \implies 3 - 6(z - 2) = 3 - 6((-2) - 2)[/tex]
[tex] \tt : \implies 3 - 6(z - 2) = 3 - 6(-2 - 2)[/tex]
[tex] \tt : \implies 3 - 6(z - 2) = 3 - 6(- 4)[/tex]
[tex] \tt : \implies 3 - 6(z - 2) = 3 + 24[/tex]
[tex] \tt : \implies 3 - 6(z - 2) = 27[/tex]
[tex] \large \underline{\boxed{\bf{ 3 - 6(z - 2) = 27}}}[/tex]
Hence, value of 3 - 6(z - 2) = 27.
Suppose we select without looking one marbles de containing 5 red marbles and 7 green marbles What is the probability of selecting each of the following a) A red marble c) A purple marble b) A green marble d) Ared or a green marble a) What is the probably 3
Answer:
a) 5/12 probability of selecting a red marble.
b) 7/12 probability of selecting a green marble.
c) 0% probability of selecting a purple marble.
d) All marbles are either red or green, so 100% probability of selecting a red or a green marble
Step-by-step explanation:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
a) A red marble
5 red marbles out of 5 + 7 = 12 total marbles
So, 5/12 probability of selecting a red marble.
b) A green marble
7 green marbles out of 5 + 7 = 12 total marbles
So, 7/12 probability of selecting a green marble.
c) A purple marble
There are no purple marbles, so 0% probability of selecting a purple marble.
d) A red or a green marble
All marbles are either red or green, so 100% probability of selecting a red or a green marble
