A.1 hour 3 minutes
B.1 hour 16 minutes
C.1 hour 35 minutes
D.2 hours 30 minutes
Answer:
It will take him 1 hour 35 minutes to finish a 10 mile race
Answer is (C)
Cody runs 10-mile in 1 hour 35 minutes.
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
Cody runs 4 miles in 38 minutes.
Now,
Since, Cody runs 4 miles in 38 minutes.
Hence, The time to run 10 miles = 38 × 10 / 4
= 380/4
= 95 minutes
= 1 hour 35 minutes
Thus, Cody runs 10-mile in 1 hour 35 minutes.

a taxicab charges $1.75 for the flat fee and $0.25 for each mile. write an inequality to determine how many miles eddie can travel if he has $15 to spend.
Answer:
1.75 +0.25m ≤ 1553 milesStep-by-step explanation:
You want an inequality to determine how many miles eddie can travel if he has $15 to spend on a taxicab that charges $1.75 for the flat fee and $0.25 for each mile.
InequalityThe mileage charge is the per-mile charge ($0.25) multiplied by the number of miles (m). It will be $0.25m.
The total charge is the mileage charge plus the flat fee. Eddie wants that to be no greater than $15.
1.75 +0.25m ≤ 15
SolutionWe can solve this inequality in 2 steps.
0.25m = 13.25 . . . . . subtract 1.75
m = 53 . . . . . . . . . . . divide by 0.25 (or multiply by 4)
Eddie can travel 53 miles if he has $15 to spend.

Answer:
m = 2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS

Step-by-step explanation:
Step 1: Define Equation
m - 4m = -6
Step 2: Solve for m
Combine like terms: -3m = -6Divide -3 on both sides: m = 2Step 3: Check
Plug in m into the original equation to verify it's a solution.
Substitute in m: 2 - 4(2) = -6Multiply: 2 - 8 = -6Subtract: -6 = -6Here we see that -6 does indeed equal -6.
∴ m = 2 is the solution to the equation.

Christie has a total of 15 pieces of fruit are bananas and apples worth $1.59 bananas are $.13 each and apples are seven cents each how many bananas and how many apples does she have
Answer:
a = apple
b = banana
a + b = 15 so a = 15 - b
0.07a + 0.13b = 1.59
substitute a = 15 - b into 0.07a + 0.13b = 1.59
0.07a + 0.13b = 1.59
0.07(15 - b) + 0.13b = 1.59
1.05 - 0.07b + 0.13b = 1.59
0.06b = 0.54
b = 0.54/0.06
b = 9
a = 15 - b
a = 15 - 9
a = 6
answer: 6 apples and 9 bananas

An 18-foot ladder is leaning against the side of a building forming a right triangle. The angle formed by the ladder and the ground is 60°. Which is closest to the distance, in feet, of the bottom of the ladder from the base of the wall?
Answer:
The distance is 9 feet
Step-by-step explanation:
18 is the length of the hypotenuse.
To find the length of the adjacent side, we take the hypotenuse multiplied by the cosine of the angle which is 60 degrees.
18*cos(60) = 9

The value of the expression given as [3² * 3⁻⁵]/[5⁻²] is 25/27
How to evaluate the expression?The expression is given as:
3 squared times 3 to the power of negative 5 end quantity over 5 to the power of negative two
Rewrite properly as:
[3² * 3⁻⁵]/[5⁻²]
Apply the negative exponent law of indices
So, we have
[3² * 3⁻⁵]/[5⁻²] = [5²]/[3⁻² * 3⁵]
Apply the exponent law of indices
[3² * 3⁻⁵]/[5⁻²] = [5²]/[3³]
This gives
[3² * 3⁻⁵]/[5⁻²] = 25/27
Hence, the value of the expression given as [3² * 3⁻⁵]/[5⁻²] is 25/27

A quadrilateral with no sides parallel and diagonals that are perpendicular
Options:
Quadrilateral
Kite
Trapezoid
Isosceles Trapezoid
Parallelogram
Rectangle
Rhombus
Square
======================================================
Explanation:
Of your original given list, let's write down the parallelograms. They are:
Parallelogram Rectangle Rhombus SquareSo we cross those off the list since we want a quadrilateral with no sides parallel. A parallelogram, by definition, is a quadrilateral with both pairs of opposite sides that are parallel.
We can also rule out the trapezoids because a trapezoid is a four sided figure (quadrilateral) where we have exactly 1 pair of parallel sides, while the other sides are not parallel.
Lastly, we can rule out the kite because any kite has perpendicular diagonals.
The only thing left is quadrilateral. In my opinion this answer should be more specific and say "quadrilateral that isn't a parallelogram, a trapezoid, or a kite", but I think I see what your teacher was going for here.

What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have,
According to the question we have been given the expression which is :
(15x^2+11y^2+8x)-(7x^2+5y^2+2x)=[blank]x^2+6y^2+6x
In this we have to find the missing coefficient.
To find the missing coefficients we will solve the L.H.S that is
= (15x^2+11y^2+8x)-(7x^2+5y^2+2x)
First we will eliminate the brackets we get
15x^2+11y^2+8x-7x^2-5y^2-2x
Solving the coefficients of x² terms , y² terms and x terms we get
= 8x² + 6y² + 6x
Which is equal to the R.H.S
Combining both the equation we get the coefficient of the x² is 8.
Hence the missing coefficient is 8.

Allen traveled for 7 hours at a constant rate of 40 miles per hour. Anna traveled the same distance at a constant rate of 50 miles per hour.
How long did it take Anna to travel the same distance as Allen?
Drag the steps in the correct order to solve the problem.
Here is the correct order of the step:
Identify: Anna's time is the unknown
Strategize : let x = Anna's time
Set up : 7(40) = x(50)
Solve: x = 5.6
Check: 7(40) = 5.6(50)
What is Anna's time?The first step is to determine the distance Allen travelled:
Distance = average speed x time
40 x 7 = 280 miles
The second step is to determine the time it took Anna to travel 280 miles.
Time = distance / average speed
280 / 50 = 5.6 hours
