Tracie would speak approximately 80 words in 120 seconds.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
We can use proportions to solve this problem.
If Tracie speaks 30 words in 45 seconds, then we can set up a proportion to find out how many words she would speak in 120 seconds:
30 words / 45 seconds
= x words / 120 seconds
Now,
45 seconds x (x words) = 30 words x 120 seconds
45x = 3600
x = 80
Therefore,
Tracie would speak approximately 80 words in 120 seconds.

What is Trigonometric ratio?Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled.
Given that, The angle of elevation from a boat to the top of a lighthouse is 25°, the lighthouse is 150 feet tall.
Let the distance from the boat to the lighthouse be x
tan25° = 150/x
x = 150/tan25°
x = 321.67
Hence, the distance from the boat to the lighthouse 321.67 ft.

Step-by-step explanation:
1. Karen has a square cartolina whose sides measure 60
cm each. She cuts the cartolina into two equal rectangles.
Find the perimeter of one piece of rectangle.
2. A rectangle has a length of 30 cm and a width smaller
by 5 cm. What is its perimeter?
If Karen cut her square cardboard into two equal rectangles, the perimeter of those rectangles is 180cm. On the other hand, if the rectangle is 25 cm wide, the perimeter would be 110 cm.
What is the perimeter of a geometric figure?
The perimeter of a geometric figure is the measure of the length of all its sides. In this case, if Karen has a square of cardboard with a side of 60cm, it can be inferred that she would have two rectangles with a height of 30cm and a base of 60cm, so the perimeter would be:
30cm + 60cm + 30cm + 60cm = 180cmOn the other hand, if the rectangle has a base of 30cm and a height of 25cm, the perimeter would be:
25cm + 30cm + 25cm + 30cm = 110cmLearn more about perimeter in: https://brainly.com/question/6465134

What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
The equation is given below.
[tex]\rm \sqrt{x^2 + 81} = x + 10[/tex]

B5 + C9 = 164
Split the numbers.
B0 +C0 +14 = 164.
B0 + C0 = 150
B + C = 15
B cannot be 1, 2, 3, 4, or 5 because that forces C to be a two digit number and C only represents 1 digit.
B cannot be 6 or 9 because they are present.
B can only be 7 or 8. C can also be 7 or 8.

Step-by-step explanation:
Answer:
Angle Relationship: Alternate exterior angles
x = -10
Angle measurement: 51 °
Step-by-step explanation:
These angles are located "outside" the two parallel lines but on opposite sides of the transversal, therefore they are alternate exterior angles.
Alternate exterior angles are congruent, therefore the angle must be 51 °
51 = 61 + x
subtract 61 from both sides
x = 10

Nancy made 20 ounces of a snack mix that was 1/5 peanuts, 30% raisins, and 5 ounces of chocolate chips. the rest was granola how many ounces of granola were in Nancy's snack mix?
Answer:
5
Step-by-step explanation:
First of all, we have a lot of different forms of part/whole's. We have a fraction, a percentage, and a number. How do we make this work???
Let's convert our percent and fraction to ounces, because that is what the question is talking about.
1/5 of 20
1/5=x/20
20=5x
/5 /5
4=x
Now lets convert our percent into ounces.
30% of 20
30/100=x/20
30(20)=100x
600=100x
/100 /100
6=x
Now we have our ounces, we now need to find what is the granola. To do that, we need to add the number of everything else, and then subtract that by the total ounces.
4+6+5=15
20-15=5
The answer would be 5 ounces of granola!
