Neil is going to a bookstore 45 miles away. The bridge was closed on the way back, so
he had to take an alternate route and had to drive 15 mph slower, which make the trip
back take 7 minutes longer. How fast was he going on the way to the bookstore?
Answers
Answer:
35 mph
Step-by-step explanation:
As you might have learned in your physics class, the average speed of a car in mph is 50. You should write this down on some paper.
After writing it down, we need to look at what the problem is asking us, so we don't get confused. " How fast was he going on the way to the bookstore?"
This means that we need to calculate his mph speed on the way to the bookstore by subtracting something.
50 mph=Average
Alternate Route= -15
After you have written THAT down in your notes, you need to ask yourself,
"What is 50-15?"
Calculating 50-15 will make the "15 mph slower" show up and calculating that with the average will get you your answer.
50-15 is 35

Answers
Answer:
45 degrees
Step-by-step explanation:
Here, we want to get the value of the acute angle
From the question, we have it that the sin of the acute angle equals its cosine
Recall;
cos A = sin (90-A)
Hence, if A is 45, then Cos A and Sine A will be the same
This means the value of theta which is the acute angle is 45 degrees

Describe the process for calculating the volume of a cone. Use complete sentences.
Answers
Answer:
Step-by-step explanation:
To find the volume of a cone, review the relevant formula:
V = (1/3)(base area)(height). If the radius of the base is given, assuming that the base is a circle, then (base area) is A = πr². Then the volume of the cone is V = (1/3)(πr²)h, where h is the height.
On a calculator, the proper sequence of commands and data would are as follows:
V = (1/3)(πr²)(h), or (on the calculator) V = (1÷3)*π*(r)^2*h.
The volume of a cone using the given formula and measurements.
To calculate the volume of a cone, you can follow these steps:
1. Identify the measurements needed: You will need to know the radius (r) and the height (h) of the cone.
2. Determine the formula: The formula to calculate the volume of a cone is V = (1/3) * π * r² * h, where V represents the volume, π is a mathematical constant (approximately 3.14), r is the radius, and h is the height.
3. Measure the radius: Use a ruler or any suitable measuring tool to determine the radius of the cone. The radius is the distance from the center of the circular base to any point along the edge.
4. Measure the height: Use a ruler or measuring tool to measure the height of the cone. The height is the vertical distance from the tip (apex) of the cone to the base.
5. Plug in the values: Substitute the values of the radius and height into the volume formula: V = (1/3) * π * r² * h.
6. Perform the calculations: Square the value of the radius (r²) and multiply it by the height (h). Then multiply that result by π (approximately 3.14). Finally, multiply the entire expression by (1/3) to obtain the volume.
7. Simplify and express the answer: Perform the arithmetic operations to obtain a numerical value for the volume. Make sure to include the appropriate unit of measurement (e.g., cubic units) based on the units used for the radius and height.

Solution given:
7x-29=2x+16[length from the circumference of circle is equal to same point]
7x-2x=16+29
5x=45
x=45/5=9
now.
XY=2×9+16=18+16=34 is your answer
The measure of tangent XY is 34.
What is tangent on a circle?If two tangents are drawn to a circle from an external point, then they are equal in length.
This property is often used in geometry problems to find the length of a tangent segment or to solve for an unknown variable.
We have,
The two tangents in a circle are equal.
So,
2x + 16 = 7x - 29
Solve for x.
2x + 16 = 7x - 29
7x - 2x = 16 + 29
5x = 45
x = 9
Now,
XY
= 2x + 16
= 2 x 9 + 16
= 18 + 16
= 34
Thus,
The measure of XY is 34.

Jordan is 12 years older than Anna. The
sum of their ages is 50. Find the age of
each person.
Answers
Answer:
Jordan age = 31 yearsAnna age = 19 yearsStep-by-step explanation:
let Jordan age be X & Anna age be Y
so,
Jordan is 12 years older than Anna.
x = y + 12 ......... (1)
The sum of their ages is 50.
x + y = 50 ........ (2)
putting value of x from (1) into (2)
x + y = 50
(y + 12) + y = 50
2y + 12 = 50
2y = 50 - 12
2y = 38
y = 38÷2
y = 19
putting value of y in (2)
x + y = 50
x + 19 = 50
x = 50 - 19
x = 31
so,
Jordan age = 31 years
Anna age = 19 years

Answers
step by step
The equivalent expression in standard form is 2x² + 7x + 5.
What is Expression?An expression is combination of variables, numbers and operators.
To write the expression in standard form, we need to simplify it by multiplying the two factors using the distributive property of multiplication:
(2x + 5)(x + 1) = 2x² + 2x + 5x + 5
Combining like terms, we get:
