Answer:
k = 42
Step-by-step explanation:
These are complementary angles so they add to 90°
90 = 47 + (k + 1)
90 - 47 = k + 1
43 = k + 1
k = 42
K=42

If 0 < f ≤ 90 and cos(22f − 1) = sin(7f + 4), what is the value of f?
f = 3
f = 4
f = 5
f = 6
Answers
Answer:
f=3
Step-by-step explanation:
The intervals means that angle f is between the quadrant 1.
Using that, we can use this identity
[tex] \sin(x) = \cos(y) [/tex]
where x+y=90
[tex]22f - 1 + 7f + 4 = 90[/tex]
[tex]29f + 3 = 90[/tex]
[tex]29f = 87[/tex]
[tex]f = 3[/tex]

Lindsey and Justin want to collect data to find out the favorite afterschool activities of 7th grade students at Schofield Middle School. Which
group of people should Lindsay and Justin survey to achieve the most accurate results?
A: all of the students in band.
B: a random selection of two girls and two boys for each 7th grade class.
C: a random selection of two girls and two boys from the chess club.
Answers
Lindsey and Justin must survey a random selection of two girls and two boys for each 7th grade class to get the most accurate results, so the correct choice is B.
StatisticsThis is so because, since precise information is required regarding a particular group of students (7th graders), it would be correct to target members of that group to obtain the first samples of information.
That is, by going to the most reliable source, a more reliable sample would be obtained.

Tres empleados de una empresa tienen que pagar 3100€ de impuestos entre todos de forma inversamente proporcional a su sueldo mensual. Si Javier cobra 1500€, Antonio, 2000€, y Elvira, 1800€, ¿cuánto tiene que pagar cada uno?
Answers
Answer:
La cantidad que Javier paga como impuesto, A es de 1.200 €
La cantidad que Antonio paga como impuesto, B es 900 €
El importe que paga Elvira como impuesto, C es de 1.000 €
Step-by-step explanation:
Dejemos que 'A', 'B' y 'C', representen la cantidad que pagan Javier, Antonio y Elvira respectivamente, y que 'k' represente la constante de proporcionalidad, por proporcionalidad inversa, tenemos;
A = k / 1500, B = k / 2000, C = k / 1800
A + B + C = 3100
∴ k / 1500 + k / 2000 + k / 1800 = 3100
Simplificando la ecuación anterior usando una calculadora gráfica da;
31 · k / 18 000 = 3100
k = 18.000 × 3.100 / 31 = 1.800.000
k = 1.800.000
La cantidad que Javier paga como impuesto, A = 1.800.000 / 1.500 = 1.200
La cantidad que Antonio paga como impuesto, B = 1.800.000 / 2.000 = 900
La cantidad que paga Elvira como impuesto, C = 1.800.000 / 1.800 = 1.000

You want to buy 7 tickets at that same rate. Explain the mathematical process you used to determine the cost of 7 tickets. (Include the unit rate in your explanation)
Answers
Answer:
7x
Step-by-step explanation:
To purchase 7 tickets at the same rate ;
Mathematically, Total Cost of an item is :
Cost = unit price * quantity
Here,
quantity = 7 tickets
Since price per ticket(rate) is the same ; then we can take rate as x
Hence, the cost of the 7 tickets is :
Quantity * rate
7 * x = 7x
A family charges a trip to the zoo on a credit card. The simple interest rate is 12%. The charges are paid after 3 months. What is the total amount paid for the trip? Round your answer to the nearest hundredth.
Answers
Answer:
$180.806
Step-by-step explanation:
The computation of the total amount paid for the trip is shown below;
As we know that
Simple interest = Principal × rate of interest × time period
= (67.70 + 62.34 + 45.50) × 12% × 3 months ÷ 12 months
= 5.2662
Now the amount is
= Principal + simple interest
= 175.54 + 5.2662
= $180.806

Solve the equation for a.
2(a + 1) = 6
+
a = [?]
Answers
Answer:
a=2
Step-by-step explanation:
Let's solve your equation step-by-step.
2(a+1)=6
Step 1: Simplify both sides of the equation.
2(a+1)=6
(2)(a)+(2)(1)=6(Distribute)
2a+2=6
Step 2: Subtract 2 from both sides.
2a+2−2=6−2
2a=4
Step 3: Divide both sides by 2.
2a /2 = 4 /2
a=2
