What is an expression?Expressions in maths are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, Simplify cos0° × tan0°
We know,
cos0° = 1
tan0° = 0
cos0° × tan0° = 0 × 1 = 0
Also, sin0° = 0
Therefore, cos0° × tan0° = sin0°
Hence, the correct option is sin0°

5. 2.5 x + 20 = 25
Answer:
x= 2
Step-by-step explanation:
Subtract 20 from both sides
2.5x + 20 − 20 = 25 − 20
2.5x= 5
Divide both sides by 2.5
2.5x/2.5= 5/2.5

Fn=total at the end of a given year(=n) (subscript)
I= interest in decimal
F=P(1+I)
at end of first year F1=P(1+I)
at end of second year F=F1(1+I)= P(1+I)(1+I)= P(1+I)^2

A prism 11 in tall with a right triangle for a base with side lengths 6 in, 8 in, and 10 in.
A) 344 in2
B) 383 in2
C) 312 in2
D) 288 in2
Answer:
You may not recognize this...but the base forms a "Pythagorean" right triangle with legs of 6 and 8 cm
The area of a right triangle is (1/2) ( product of leg lengths)
So...the area of the base = (1/2) (6 * 8 ) = (1/2) 48 = 24 cm^2
And the volume of the prism is just the base area x height = 24 x 7 = 192 cm^2

The total amount kate had left is 4.20$ after buying 7 pencils at p cents. Please explain how do I answer this question and find the value of p
Answer:
each pencil almost costs 83 cents which is the value of p
Step-by-step explanation:
Here most important data that the amount which Kate had before the purchase of pencils is missing.
For our convenience i am assuming Kate had $10 before the purchase of pencil.
Since, after purchase the left with Kate = $4.20
Therefore, amount spend on purchase of pencils = $10-$4.20 = $5.80
In $5.80 Kate purchased 7 pencils
Therefore cost of each pencil p = 5.80/7 = $0.8285 ≅ $0.83
Therefore each pencil almost costs 83 cents which is the value of p

The longer April exercises, the more calories she burns.
1.Time spent exercising
2.Calories burned
Answer:
1
Step-by-step explanation:
because when April stops exercise the calories burnt will reduce
Answer:
it's Time spent exercising.
Step-by-step explanation:
Time spent exercising does not rely on calories burned for its value to change. However, the time spent exercising will determine how many calories are burned. This shows that calories burned is dependent on time spent exercising while time spent exercising is an independent variable.
Let n represent the time in hours for the service call and C represents the total cost in dollars. Write an equation that relates C and n
Answer:
C(n) = pn
Step-by-step explanation:
Given :
n = time in hours for service call
C = total cost
Total cost = unit cost per hour * time in hours
If unit cost per hour = p

The value of measure of angle R is,

What is mean by Angle?An angle is a combination of two rays with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Reference angle = R
Side opposite to R = 5 cm
Adjacent side length = 12 cm
Thus, applying TOA, we have:
Tan R = opposite/adjacent
Tan R = 5/12
R = tan⁻¹ (5/12)
R ≈ 22.62°
Thus, The value of measure of angle R is,

After 4 days, a bookstore has 140 copies of a new title still on hand. After 9 days, the bookstore has 50 copies still on hand. Model this situation by writing an equation of the form c(t)=mt+b where c is the number of copies still on hand after t days of being available
Answer:
[tex]c(t) =-18t +212[/tex]
Step-by-step explanation:
Given
[tex](t_1,c_1) = (4,140)[/tex]
[tex](t_2,c_2) = (9,50)[/tex]
Required
Determine the equation
First, we calculate the slope (m)
[tex]m = \frac{c_2 - c_1}{t_2 - t_1}[/tex]
[tex]m = \frac{50 - 140}{9-4}[/tex]
[tex]m = \frac{-90}{5}[/tex]
[tex]m = -18[/tex]
The equation is then calculated as:
[tex]c =m(t - t_1) + c_1[/tex]
[tex]c =-18*(t - 4) + 140[/tex]
[tex]c =-18t +72 + 140[/tex]
[tex]c =-18t +212[/tex]

The numbers 1 - 30 are written down on pieces of paper and placed in a hat for
students to to randomly select.
Answer:
Event A = 1/3
Event B = 1/6
Step-by-step explanation:
The probability of drawing a number between 1 and 10 (Event A) is approximately 0.3333 or 33.33%.
To calculate the probability of Event A, we need to determine the total number of favorable outcomes (numbers between 1 and 10) and divide it by the total number of possible outcomes (all numbers from 1 to 30).
Counting the favorable outcomes:
Event A consists of numbers between 1 and 10. So, there are 10 favorable outcomes: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.
Counting the total possible outcomes:
The hat contains numbers from 1 to 30. So, there are 30 possible outcomes: {1, 2, 3, ..., 30}.
Calculating the probability of Event A (P(A)):
The probability of an event is given by the formula:
P(A) = (Number of Favorable Outcomes) / (Total Number of Possible Outcomes).
In this case,
P(A) = 10 (favorable outcomes) / 30 (total possible outcomes)
P (A) = 1/3 ≈ 0.3333 or 33.33%.
