The difference of twice a number and 3 is at most -21

Answers

Answer 1

Answer:

The equation: 2n - 3 ≤ -21

The answer to the equation: n ≤ 9

Step-by-step explanation:

How to get the equation:

The difference of symbolizes subtraction. Because we are subtracting twice a number and 3, the first part of the equation can be written as 2n - 3. The n symbolizes the number.

is at most symbolizes a less than or equal to sign. That sign is ≤. And what is it less than or equal to? -21.

Now are equation is 2n - 3 ≤ -21

How to solve it:

2n - 3 ≤ -21

Add 3 to both sides of the equation

2n ≤ 18

Divide both sides of the equation by 2

n ≤ 9

Each day Marisa runs the same distance. She ran 35 miles in the last 5 days. What is the unit rate?

Answers

Answer:

7 miles

Step-by-step explanation:

As, we will take unit rate as "x"

So, for one day = x distance

For 5 days = 5(x)

For 5 days she covered 35 miles

So therefore,

5(x) = 35 miles

X= 35/5

X=7 miles

For a day= 7 miles are covered

On a coordinate plane, a curved line with a minimum value of (5.1, negative 7) and a maximum value of (0, 25), crosses the x-axis at (negative 3.4, 0), (3.9, 0), and (6, 0), and crosses the y-axis at (0, 25).
Which statement is true about the local minimum of the graphed function?

Over the interval [–4, –2], the local minimum is 0.
Over the interval [–2, –1], the local minimum is 25.
Over the interval [–1, 4], the local minimum is 0.
Over the interval [4, 7], the local minimum is -7.

Answers

Answer:

D

Step-by-step explanation:

The rest of the question is the attached figure and the statement options.

A. Over the interval [–4, –2], the local minimum is 0.

B. Over the interval [–2, –1], the local minimum is 25.

C. Over the interval [–1, 4], the local minimum is 0.

D. Over the interval [4, 7], the local minimum is -7.

============================================================

According to the graph, we will check the options:

A. Over the interval [–4, –2], the local minimum is 0.  (Wrong)

Because the minimum is -12

B. Over the interval [–2, –1], the local minimum is 25.   (Wrong)

Because the minimum is 18

C. Over the interval [–1, 4], the local minimum is 0.  (Wrong)

Because the minimum is at x = 4 less than zero

D. Over the interval [4, 7], the local minimum is -7.    (True)

Of the 50 students in the cafeteria, 7 have red hair. Suppose there are 750 students in the school. Write a proportion that could be used to predict the number of students who have red hair. Use x to represent the number of students who have red hair.

Answers

Given:

Of the 50 students in the cafeteria, 7 have red hair.

Total number of students = 750

To find:

The proportion that could be used to predict the number of students who have red hair.

Solution:

Let x represent the number of students who have red hair.

The ratio of student having red hair to the total number of students are

[tex]Ratio_1=\dfrac{7}{50}[/tex]

[tex]Ratio_2=\dfrac{x}{750}[/tex]

The number of students having red hair is proportional to the total number of students. So, the above ratios are equal.

[tex]\dfrac{x}{750}=\dfrac{7}{50}[/tex]

Multiply both sides by 750.

[tex]\dfrac{x}{750}\times 750=\dfrac{7}{50}\times 750[/tex]

[tex]x=7\times 15[/tex]

[tex]x=105[/tex]

Therefore, the required equation is [tex]\dfrac{x}{750}=\dfrac{7}{50}[/tex] and the number of students who have red hair is 105.

The scale of a map says that 2 cm represents 10 km. What is the actual number of kilometers that is represented by 6 centimeters on the map?

Answers

Answer:

6 times 10 to the minus 5

6 cm on the map represents 30 kilometers in reality, with a scale of 2 cm representing 10 km.

In the given map, the scale is 2 cm represents 10 km.

Each centimeter on the map represents 5 km (10 km divided by 2 cm).

We can use the scale of the map, which states that 2 cm represents 10 km, to determine the precise number of kilometers that 6 centimeters on the map represent.

If 2 cm represents 10 km, then 1 cm represents 10 km / 2 cm = 5 km.

6 centimeters on the map represent 6 cm × 5 km/cm = 30 kilometers in reality.

Explain how to use the distributive property to find the product 3 x 4 1/5

Answers

Answer:

12.6

Step-by-step explanation:

The answer is 12.6 and here is the explanation of using the Distributive Property. Because we are multiplying a whole number by a mixed number, we have to multiply the whole number by the whole number in the mixed number and then multiply the whole number by the fraction. In this case, we have 3 x 4 1/5. We multiply 3x4=12 first, and then we multiply 3x1/5 to get 0.6. 12+0.6=12.6. Hope it helps!
