Answer:

4 lines/sticks + 7 individual squares

Step-by-step explanation:

Decimal = 0.47

We can break 0.47 into 0.4 + 0.07. We can use 4 of the lines/sticks to represent 0.4 because the whole grid is equal to 1. We can use 7 individual squares to represent 0.07 because 1/100 is the same as one of the individual squares.

Answer:

1/2 and -1/2

Step-by-step explanation:

The square root of a fraction is equal to the square root of the numerator divided by the square root of the denominator. In this case, it is √1 / √4. The square root of 1 is still 1, so 1 is the numerator. The square root of 4 is 2, so 2 is the denominator. The fraction is 1 / 2. However, if you square -1/2, you also get 1/4, just like when you square 1/2. Therefore, the second choice is the right option because it has the correct, and number of, answers.

Answer:

5(2+y)

Step-by-step explanation:

The sum of 2 and y = 2+y
So,

5 times the sum of 2 and y(2 + y)  = 5 × (2+y) = 5(2+y)

The answer is 5(2+y)

Answer:

A. 3(2 + y)

Step-by-step explanation:

It's A. 3(2 + y) because when an equation is in parentheses then you have to do it first. So you would work out 2 + y and then multiply it by 3.

Answer:

56

Step-by-step explanation:

Answer:

56 containers

Step-by-step explanation:

There are 8 pints in 1 gallon

8 x 7 = 56

Answer:

Solution

Let last year and new year be L(y) and N(y)

Let last year Expired box and new year Expired box be L(E) and N(E)

Here,

L(y)=300 box

L(E)=25 box

N(y)=400 box

N(E)=x

We know,

N(y) / L(y) = N(E) / L(E)

400/300 = x/25

1.333333333 = x/25

x = 1.333333333 * 25

x = 33.333333333

So, the expire box this year is 33.333333333

Answer:

x = 6

Sorry if this answer is not correct, if it is or is not, please tell me in the comments!

Step-by-step explanation:

All of the angles add up to 180 degrees (since it is a triangle), so

(11x - 3) + (7x + 5) + (13x - 8) = 180

Then, combine the like terms.

31x - 6 = 180

Now, out goal is to separate the x from everything. To do that, we need to add 6 to 180.

31x = 186

Then divide by 31.

x = 6

(Feel free to replace x with 6 back in the previous equation to double check it!)

The mean of 5 is because it includes the outlier more than the median

Step-by-step explanation:

Mean: ->             5

2 + 2 + 3 + 3 + 3 + 4 + 4 + 19 = ? / 8

40 / 8 = 5

Median: ->              3

Answer:

2

Step-by-step explanation:

The average rate of change of the equation during the interval 4 ≤ x ≤ 10

can be represented in this expression if f(x) is substituted for y:

[tex]\dfrac{f(10)-f(4)}{10-4}[/tex]

[tex]=\dfrac{17-5}{6}[/tex]

[tex]=\dfrac{12}{6}[/tex]

[tex]=2[/tex]

So, the average rate of change (AOC) is 2.

You also could just figure this out by looking at the slope. Since this is a linear equation, the AOC over any interval will always be the same as the slope, since the slope is constant.

Properties of Parallel Lines

Given:

lime m || n

So, using the property of parallel lines we have the angles on the same side of transversal are supplementary

x- 5 + 2x +14= 180

3x + 9 = 180

3x = 171

x= 171/3

x= 57

Hence, the value of x is 57.

Given the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days stretch is 55.5 miles.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here, we have,

Expression for the Total of Distance ran by Maria

Total distance = Distance ran each day × Number days

Given the data in the question;

Distance ran each day by Maria Dm = 3.7miles

Number days ran n = 15days

Total number of distance ran by Maria TDm = ?

Hence, Total distance = Distance ran each day × Number days

TDm = Dm × n

We substitute in our values

TDm = 3.7miles × 15

TDm = 55.5miles

Thus, the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days stretch is 55.5miles.
