Answers
Answer: ⁻[tex]\frac{5}{13}[/tex] , 24.5 , 0.01
Step-by-step explanation:
13a = -5
[tex]\frac{13a}{13}[/tex] = ⁻[tex]\frac{5}{13}[/tex]
12 - b = 12.5
b - 12 + 12 = 12.5 + 12
b = 24.5
-0.1 = -10c
-10c ÷ (-10) = -0.1 ÷ (-10)
c = 0.01
PLEASE HELP!!! The amount of polonium-210 remaining, P(t), after t days in a sample can be modeled by the exponential function P(t) = 100e−0.006t, where 100 represents the initial number of grams in the sample. What is an equivalent expression, written as a percentage rate of polonium-210 lost, and how much polonium-210 remains (rounded to the nearest whole number) after 16 days?
Hint: Find the value of e−0.006 on your calculator. (7 points)
P(t) = 100e0.006t, 109 grams remain
P(t) = 100e0.994t, 3 grams remain
P(t) = 100(0.994)t, 91 grams remain
P(t) = 100(0.994)−t, 91 grams remain
Answers
Answer:
[tex]P(t)=100(0.994)^t[/tex]
Step-by-step explanation:
A calculator shows the value of [tex]e^{-.006} \approx 0.994[/tex] meaning that each day, about 99.4% of the sample remains.
The formula [tex]P(t)=100e^{-0.006t} = 100(e^{-0.006})^t=100(0.994)^t[/tex]
Evaluate this at t = 16 to get 91 grams remain.
A bird is flying at an altitude of 400 feet and descending to its nest located in a tree 20 feet above the ground. The angle from the nest to the bird is 24 degrees. Approximately how far is the bird from the nest.
ANSWER:
The answer is 934 If you make a right triangle with 380 as the height because the bird has 380 ft to go until the nest then you make the angle 24 opposite to that side. After you use sin to find the missing side which is 380/x= sin24 the answer you get is rounded.

1 Professor Peterson is buying a writing
desk. The width of the desk must be less
than 4 ft.
HELP
Answers
The inequality of the width of the desk must be less than 4 ft is w < 4.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Inequalities are mathematical statements that compare two expressions using symbols like "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "!=" (not equal to).
In this case, the problem states that the width of the desk must be less than 4 ft.
We can use the symbol "<" to indicate that the width (w) is smaller than 4 feet. Therefore, we can write the inequality as w < 4, which means that any value of w that is less than 4 feet satisfies the given condition.
Thus,
The width of the desk must be less than 4 ft is w < 4.

a. What is the total running distance of the four runners?
b. Jada ran how much farther than Noah?
Answers
Answer:
26.56300 1.97700
Step-by-step explanation:
You add up all of them which was 26.5630 then you do 7.1-5.123+1.97700
Answer:
a. 26.563 milesb. 1.977 milesStep-by-step explanation:
Given,
Distance Noah ran = 5.123 miles
Distance Andre ran = 6.34 miles
Distance Jada ran = 7.1 miles
Distance Diego ran = 8 miles
Hence,
a. Total running distance of four runners
= (5.123 + 6.34 + 7.1 + 8) miles
= 26.563 miles (Ans)
b. Distance more ran by Jada than Noah
= (7.1 - 5.123) miles

Each serving of a certain fruit snack contains 90 calories. a) Han wants to know how many calories he gets from the fruit snacks. Write an equation that shows the number of calories, c, in terms of the number of servings, n.
Answers
Answer:
c = 90n
Step-by-step explanation:
Let
Number of calories = c
Number of servings = n
Calories per serving = 90
Number of calories = Calories per serving × Number of servings
c = 90 × n
c = 90n
For example, if the number of servings is 4
c = 90n
c = 90 × 4
c = 360 calories

A tank contained 80 liters of water. The function “w” represents the relationship between “t”, time in minutes, and the amount of water in the tank in liters. The equation w(t) = 80 - 2.8t defines this function. How would the graph of the inverse function of compare to the graph of “w”? PLEASE HELP!!
Answers
w(t) tells you the amount of water w at a given time t.
The inverse function tells you at which time t the tank contains an amount of water w.
To get the inverse function, solve the equation
w = 80 - 2.8t
for t :
w = 80 - 2.8t
2.8t = 80 - w
t = (80 - w) / 2.8
t ≈ 28.57 - 0.357 w
The graph of w(t) is a downward-sloping line. The graph of the inverse is also a downward-sloping line, but its intercept (28.57) and slope (-0.357) are both smaller than the intercept and slope of w(t).

A map says that 4 centimeters represents 10 kilometers. What is the real distance that 18 centimeters represents?
Answers
Answer:
The real distance that 18 centimeters represent is 45 kilometers.
Step-by-step explanation:
In this case, you can use a rule of three to find the real distance that 18 centimeters represent given that 4 centimeters represent 10 kilometers:
4 cm → 10 km
18 cm → x
x=(18*10)/4
x=45 km
According to this, the answer is that the real distance that 18 centimeters represent is 45 kilometers.
