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
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.

Mike has attempted 84 free throws. Of those attempted,
63 have gone in the basket. Based on this rate, what is the
probability that Mike's next free throw attempt will go in
the basket?
Answer:
63 ÷ 84 = 0.75 // 75% // 3/4
Step-by-step explanation:
63 divided by 84 equals 0.75, 75%, or 3/4. meaning the probability of Mike making his next free throw 75%
X = 10
3x + 5y = 20
What is the solution (x,y) of the system of equations?
Answer:
X=10
Y=-2
Step-by-step explanation: The value of X is given therefore you use it to find the value of Y in the equation:
3(10)+5y=20
5y=20-30
5y=-10
5y/5=-10/5
5 is cancelled out leaving y=-2

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

_______ is the amount of space________ a two-dimensional shape. It can be measured in units such as_______ or _________
Answer:
Area; inside; centimeters; meters.
Step-by-step explanation:
Area is the amount of space inside a two-dimensional shape. It can be measured in units such as centimeters or meters.
In Mathematics, it is typically used to measure the amount of space contained in two-dimensional shapes such as a square, rectangle, circle, sphere, etc.
Consider the area of the following shapes;
I. The area of a circle = πr²
Where, r is the radius of the circle.
II. Area of square = L²
Where, L is the length of its sides.
III. Area of rectangle = Length * width.
Answer:
Area; inside; centimeters; meters.
Step-by-step explanation:
Area is the amount of space inside a two-dimensional shape. It can be measured in units such as centimeters or meters.
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.
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

1 Professor Peterson is buying a writing
desk. The width of the desk must be less
than 4 ft.
HELP
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.

Tickets to the movies cost $9.50 for adults and $6.50 for kids. A large group bought 12 tickets and spent a total of $87. How many kid's tickets did the group purchase?
Please include an equation.
Answer:
12
Step-by-step explanation:
Answer:
9 kids tickets
Step-by-step explanation:
Let k = no. of kid's tickets
12 - k = no. of adult's tickets
9.50(12 - k) + 6.50k = 87
95(12 - k + 65k = 870
1140- 95k + 65k = 870

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.
Answer:T he bird will land at a radios of 20 feet in th air.

A map says that 4 centimeters represents 10 kilometers. What is the real distance that 18 centimeters represents?
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.

b. Jada ran how much farther than Noah?
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
