What is word problem?
Our comprehensive list of math problems focuses on addition, subtraction, multiplication, division and more specific operations. A math problem is a math question written in one or more sentences that asks a child to apply math knowledge to the "real world." life scenario. This means that children need to be familiar with the vocabulary related to the mathematical symbols they used to understand the meaning of word problems.
Here Mike spent $11.19 on a bag of red and blue candies and both candies weigh 11 lbs
=>Red candies weigh x lbs
=>Blue candies weigh (11-x) lbs
Here cost of x red candy is
=>$1.29/lb* x lbs of red candy
=> 1.29x
Now ,(11-x) lbs of blue candy costs $0.79 (11-x) = $8.69-0 .79 x
Due to the problem, $8.69 - 0.79 x + 1.29 x = $11.19
or $0.50 x = $11.19 - $8.69 = 2.50 $
or $50 x / 100 = $250 / $100
or $50 x = 250 $
or x = 250/50 = 5, red The candy weighs 5 pounds
The blue candy weighs =11-x=11–5=6 pounds
Therefore mike bought 5 pounds of red candy and 6 pounds of blue candy.

Some other names for the unit rate are:
Constant of proportionality.Slope.Gradient.Rate of change.How is called the unit rate?A general proportional relation is written as:
y = k*x
You can see that it goes through the origin because when we evaluate in x = 0, we get:
y = k*0 = 0
So it passes through (0, 0).
The value "k" has several names, unit rate is the one given here, but it is generally called the "constant of proportionality"
It is also called the slope (like in a linear equation with an y-intercept equal to 0).

Grayson biked 45 miles in 3 hours. Maya biked 26 miles in 2 hours. If they both kept a constant speed, how much faster did grayson bike than maya? write your answer as a decimal or a whole number. Miles per hour.
The required difference in the speed of Grayson ans Maya is 2 miles per hour.
What is speed ?Speed is characterized as. The pace of progress of position of an article toward any path. Speed is estimated as the proportion of distance to the time in which the distance was covered. Speed is a scalar amount as it has just bearing and no extent.
According to question:Grayson biked 45 miles in 3 hours
His speed = 45/3 = 15 miles/hour
Similarly,
Maya biked 26 miles in 2 hours
So, his speed = 26/2 = 13 miles /hour
Difference in their speed = 15-13 = 2 miles per hour
Thus, Speed of Grayson is 2 miles/hour greater than Maya.

Jamie buys a box of blue tiles that will cover 4ft2 . What percent of the floor can she tile using this box ? Does Jaime need to buy another box of blue tiles explain
The blue tiles on the floor is an illustration of proportions. The blue tiles will cover 25% of the floor
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
From the complete question, the dimension of the floor is 4 ft by 4 ft.
So, the area of the floor
Area = 4 x 4
Area = 16
The blue tiles cover 4 square feet.
So, the percent of floor is:
= 4/16 x 100
= 1/4 x 100
= 25%
Hence, the blue tiles will cover 25% of the floor. Also, he doesn't need to buy another set of blue tiles.

Calculate the length of x
Answer:
x = 13.85 cm
Step-by-step explanation:
Forming the equation,
→ (16)² = (x)² + (8)²
Now the value of x will be,
→ (16)² = (x)² + (8)²
→ 256 = x² + 64
→ x² = 256 - 64
→ x = √192
→ x = 13.8564
→ [ x = 13.85 ]
Hence, value of x is 13.85.

You have to specify the power output of a motor for a ski tow rope that will carry 25 skiers at a time. The grade of the ski slope is 32 above horizontal and the average coefficient of kinetic friction between skis and snow is 0.12. The tow speed is to be 2.0 m/s and each skier has an inertia of 60 kg (a reasonable average value)
The power output of a motor for a ski tow rope is 6925.333 Watt.
We are know that,
Speed = v = 2.0m/s
Mass = m = 60kg
Number of skier = N = 25

Explain your reasoning.
An equilateral right angled triangle is not possible because a triangle can only consist of 180°. Since a right angle is 90°, there is no way that a triangle can be have three right angles. 180° ≠ 270°
An isosceles acute triangle is possible because two angles can be acute and have the same degree values and the last angle can have a different value of another acute angle. The two angles that are acute would have the same value for their corresponding sides.
A scalene obtuse triangle is possible because one angle can be obtuse and the other ones can be acute. All the sides can be different.

Total marbles: 37 + 15 = 52
According to the number of red cards out of all the cards, there is a 15/52 possibility that a red card will be pulled during our initial pull.
Depending on how many red/total marbles are still in there, there is a 14/51 probability that the second marble pulled will also be red.
Our two fractions are multiplied together from here,
15/52 * 14/51
We can start by simplifying a little bit; the numbers 14 and 52 share a 2;

Compound InterestThe compound interest is the interest-based on the initial principal amount and the interest collected over the period of time. The formula for compound interest can be derived from the formula for simple interest. The formula for simple interest is the product of the principal, time period, and rate of interest (SI = ptr/100). Before looking into to derivation of the formula for compound interest, let us understand the basic difference between simple interest, compound interest computation. The principal remains constant over a period of time, for simple internet computation, but for compound interest computation the interest is added to the principal, for compound interest computation.
