Answer:
C. 5/13
Step-by-step explanation:
Remember SOHCAHTOA
Sine is opposite over hypotenuse. The side opposite the 23° angle is 5, and the hypotenuse is 13.
So, sin 23° = 5/13
The value of sine 23 from the provided triangle can be expressed as [tex]\frac{5}{13}[/tex], option C is correct.
What are the basic principles of trigonometry?Trigonometry has three fundamental operations: sine, cosine, and tangent. The cotangent, secant, and cosecant are three crucial trigonometric functions that can be derived from these three fundamental ratios or functions. These functions serve as the foundation for all the key ideas in trigonometry.
[tex]Sine x = \frac{opposite}{ hypotenuse. }[/tex]
side opposite = 5,
the hypotenuse= 13.
[tex]sin 23 = \frac{5}{13}[/tex]
Therefore, option C is correct.

Trinity and Peyton were collecting box tops for their class. Trinity collected 36 box tops. Peyton collected
1 ½ times as many. How many cans did they collect all together?
Answers
Note: We need to find the number of total box tops instated of total number of cans.
Given:
Trinity collected 36 box tops.
Peyton collected [tex]1\dfrac{1}{2}[/tex] times as many as Trinity.
To find:
The number of box tops they did collect all together.
Solution:
It is given that,
Number of box tops collected by Trinity = 36
Number of box tops collected by Peyton = [tex]1\dfrac{1}{2}\times 36[/tex]
= [tex]\dfrac{3}{2}\times 36[/tex]
= [tex]54[/tex]
Total = [tex]36+54[/tex]
= [tex]90[/tex]
Therefore, the total number of box tops collect all together is 90.
In ΔRST, r = 620 inches, s = 840 inches and t=230 inches. Find the area of ΔRST to the nearest square inch.
Answers
Answer:
24179 square inches
Step-by-step explanation:
In ΔRST, r = 620 inches, s = 840 inches and t=230 inches. Find the area of ΔRST to the nearest square inch.
We use the formula
Heron's formula = √s(s - a)(s - b)(s - c)
Where s = a + b + c/2
Solving for s
s = 620 + 840 + 230/2
s = 845
Solving for the area of the triangle
= √845 × (845 - 620) × (845 - 840) × (845 - 230)
= √584634375
= 24,179.213696893 square inches
Approximately = 24179 square inches

Answers
Answer:
Step-by-step explanation:
When we proceed from left to right on a number line, numbers get bigger.
That means (-5) on the given number is the least and 5 is the greatest.
By this rule, order of the numbers will be,
-4.2, -3.5, -2.1, -1.5, -1, -0.5, 0.5, 3.5, 4.8
Now we can place these numbers on the number line as shown.

C. 33 + ℓ ≥ 776; ℓ ≥ 743; A ≥ 33(743)
D. 2(33) + 2ℓ ≥ 776; ℓ ≥ 355; A ≥ 33(355)
Answers
Answer:
D. 2(33) + 2ℓ ≥ 776; ℓ ≥ 355; A ≥ 33(355)
Step-by-step explanation:
Answer:
Width of the rectangle is given to be 33 centimeters
Let the Length of the rectangle be x centimeters
So, Perimeter of rectangle is given by formula : Perimeter = 2 × (Length + Width)
⇒ Perimeter = 2 × (x + 33)
⇒ Perimeter = 2x + 66
Now, The perimeter of the rectangle is at least 776 centimeters
⇒ Perimeter > 2x + 66
⇒ 776 > 2x + 66
⇒ 2x < 710
⇒ x < 355
So, The length of the rectangle must be less than 355 cm
⇒ Area of the rectangle < 355 × 33
⇒ Area of the rectangle < 11715 cm²
How do I do this with explaination too
Answers
Answer:
27
Step-by-step explanation:
1. Using PEMDAS, you would start with all numbers inside the parentheses
2. Next inside the parentheses are exponents
3² = 3*3 = 9
2³ = 2*2*2 = 4*2 = 8
2² = 2*2 = 4
3. Go back inside the parenthese now that everything is multiplied out
[tex]\frac{9 *(8+4) }{4}[/tex] = 9* ( 12)/4 = 108/4
4. Simplify the fraction by dividing 108 by 4
108 ÷ 4 = 27
