So so far your total is $13.65

The shipping fee is $3

$3+$13.65= $16.65

Mu is walking laps to raise money for charity. For each lap she walks, her sponsors will donate $7. Mu has walked l laps and raised a total of $150

Write an equation to describe this situation.

Answers

Answer:

7[tex]l[/tex]=150

Step-by-step explanation:

Each lap is worth $7, so if Mu walked [tex]l[/tex] laps and the total is $150, then the equation would be

7[tex]l[/tex]=150

7l=$150
l= 21.82 so mu would have to walk 22 laps to make $154 ; 21 laps would only make $147 . And there is no such thing as 21.82 laps .
However if you only needed the equation it is 7l=150

The weight of the square is 10 grams
how much heavier is the circle then the triangle
Will be marked BRAINLIEST

Answers

Answer:

The circle is 2 times heavier than the triangle.

Step-by-step explanation:

We can see this by identifying the amount of squares there are per shape.

Since there are 3 triangles and 3 circles on each side, we can identify how heavy each one is by comparing them to the squares.

There are 2 squares per triangle and 1 square per circle, so we know that the circles are 2 times heavier than the triangles.

The weight of the circle is 10 grams heavier than the weight of the triangle.

What is the solution to the equation?

In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.

The weight of the square is 10 grams. Let 'x' and 'y' be the weight of the triangle and circle. Then the equation is given as,

x + 20 + x + 20 + x + 20 = y + 10 + y + 10 + y + 10

Simplify the expression, then we have

x + 20 + x + 20 + x + 20 = y + 10 + y + 10 + y + 10

3x + 60 = 3y + 30

x + 20 = y + 10

y = x + 10

The weight of the circle is 10 grams heavier than the weight of the triangle.

Four runners completed in a 10-kilometer relay race. Each Runner ran the same distance. What was that distance?

Answers

Answer:

each runner ran 2.5 kilometers

Step-by-step explanation:

10÷4=2.5

The distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.

What is division?

A method of dividing something into equal parts is called division. It produces a fair distribution of resources and is one of the four basic operations in mathematics.

How to solve this problem?

Total distance = 10 kilometers

Total number of runners = 4

Since they all covered the same distance,

the distance = 10/4 = 2.5 kilometers

Therefore, the distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.

.On a radio morning show, every 12th caller receives concert tickets, and every 16th caller receives an autographed album. What caller number will receive both

Answers

Hello!
Let’s write out the multiples of 12 and 16.
12: 12,24,36,48,60,72
16: 16,32,48,64,80,96
Since 48 is in both, caller number 48 will get both

The caller number will receive both would be 48.

What is Least common multiple?

The Least common multiple of two or more numbers are the smallest number that is multiple of two or more numbers.

Given that;

On a radio morning show, every 12th caller receives concert tickets, and every 16th caller receives an autographed album.

Now,

Since, On a radio morning show, every 12th caller receives concert tickets, and every 16th caller receives an autographed album.

Hence, The common caller number is find by calculating the LCM of 12 and 16.

⇒ LCM of 12 and 16 = 48

Thus, The common caller number which receive both will be 48.

Calculate the approximate area of the shape to the nearest cm2.

Answers

This is very simple. So you use two formulas:

Rectangle: Length • Width

Semicircle: Area = [tex]\frac{\pi r^2}{2}[/tex]

With that, you do 0.8 ÷ 2 = 0.4 because we will be using radius. When solved, you get 0.2512... But for this problem, I will be rounding everything to the nearest hundredths.

Area of semicircle: ≈ 0.25

Now we solve for the rectangle. That is very easy. Just multiply 0.75 • 0.8 and you get 0.6

For this problem, I'm not sure why they make you round to the nearest centimeter, but if you do, you get 1 cm. Otherwise,

Round to nearest tenth: 0.9

Round to nearest hundredths: 0.85
