Answer/Step-by-step explanation:
Apply the formula for area of a triangle with an included angle and two given side lengths, A = ½*a*b*Sin(θ)
15. a = 3 cm,
b = 3 cm,
θ = 140°
A = ½*3*3*Sin(140)
A = 2.89 ≈ 2.9 cm² (nearest tenth)
16. a = 5 yd,
b = 8 yd,
θ = 98°
A = ½*5*8*Sin(98)
A = 19.81 ≈ 19.8 yd² (nearest tenth)
17. a = 5 cm,
b = 6 cm,
θ = 152°
A = ½*5*6*Sin(152)
A = 7.04 ≈ 7.0 cm² (nearest tenth)
17. a = 5 m,
b = 6 m,
θ = 150°
A = ½*5*6*Sin(150)
A = 7.5 ≈ 7.5 m² (nearest tenth)

The bowling team at Lincoln High School must choose a president, vice president,
and secretary. If the team has 12 members, how many ways could the officers be
chosen?
Answers
Answer:
The officers can be chosen in 1320 ways.
Step-by-step explanation:
The order in which the officers are chosen is important(the first is president, second vice president and third secretary) which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
3 officers from a set of 12. So
[tex]P_{(12,9)} = \frac{12!}{9!} = 1320[/tex]
The officers can be chosen in 1320 ways.

f(x) = 1/2x-3
x=
The input is
when the output is -3.
Answers
Given:
[tex]y=f(x)[/tex]
[tex]f(x)=\dfrac{1}{2}x-3[/tex]
To find:
The input when the output is – 3.
Solution:
We have,
[tex]f(x)=\dfrac{1}{2}x-3[/tex]
Substituting [tex]f(x)=y[/tex], we get
[tex]y=\dfrac{1}{2}x-3[/tex] ...(i)
We need to find the input when the output is – 3. It means, we have to find the value of x when [tex]y=-3[/tex].
Putting [tex]y=-3[/tex] in (i), we get
[tex]-3=\dfrac{1}{2}x-3[/tex]
[tex]-3+3=\dfrac{1}{2}x[/tex]
[tex]0=\dfrac{1}{2}x[/tex]
Multiply both sides by 2.
[tex]0=x[/tex]
Therefore, the input is 0 when the output is -3.

A summer camp has 492 campers who will be going on an outing. Estimate the number of vans needed to accommodate the entire camp if each van can comfortably
hold 12 passengers. Then calculate the actual number of vans that will be needed.
Answers
Answer: 41 vans will be needed.
Step-by-step explanation:
There are a total of 492 campers. We know that each van can hold a total of 12 passengers.
So, simply divide 492 by 12 to get the total amount of vans needed.
492/12 = 41 vans.

If A is a 2x2 matrix and B is a 2x1 matrix, what is the dimension of AB?
Answers
Answer:
2x2 matrix
Step-by-step explanation:
Given
Dimension of matrices A = 2x2 matrix
Dimension of matrices B = 2x1 matrix
The dimension of matrix AB can be gotten by cancelling the row of matrices 1 and column of matrices 2.
After cancelling both row and column, the remaining dimension will be 2x2 matrix. Hence the dimension of AB is 2x2 matrix

1) x = 8
2) ∠RPS = 36°
Step-by-step explanation:
GIVEN :-
∠QPS = 180°∠QPR = 7x + 88∠RPS = 3x + 12TO FIND :-
Value of xMeasure of ∠RPSFACTS TO KNOW BEFORE SOLVING :-
In a straight line , if there are two angles such that their sum is equal to straight angle (or 180° in other words) , then those angles are known as linear pair.
PROCEDURE :-
1)
Measure of ∠QPS = 180° and it comprises of ∠QPR & ∠RPS.
⇒ ∠QPR & ∠RPS are linear pair.
⇒ ∠QPR + ∠RPS = 180°
⇒ 7x + 88 + 3x + 12 = 180°
⇒ 10x + 100 = 180
⇒ 10x = 180 - 100 = 80
⇒ x = 80/10 = 8
2)
x = 8. So,
∠RPS = 3×8 + 12 = 24 + 12 = 36°

What is the measure of angle of 1?
Answers
Answer:
m<1 = 118
Step-by-step explanation:
The remote angles theorem states that when one extends one of the sides of a triangle, the sum of the two non-adjacent angles is equal to the measure of the angle between the extension of the side and a side of a triangle. One can apply this theorem here by stating that
(28) + (90) = m<1
Remember, a box around an angle signifies that its measure is (90) degrees.
Solve this problem by performing the operation,
118 = m<1
