Answer:

Inequality: 2*x + 3 ≤ 11

Solution: x ≤ 4

Number line: see picture attached (in the context of the problem, x must be greater than zero)

The solution means that you can buy at most 4 pounds of strawberries

Step-by-step explanation:

You go to the store to buy fruits. You have $11, you need 2 pounds of apples that costs $3, and you want strawberries, which cost $2 each pound. How many pounds of strawberries can you buy?

The inequation that represent this situation is:

2*x + 3 ≤ 11

where x represents pounds of strawberries. The solution is get as follows:

2*x + 3 - 3 ≤ 11 - 3

2*x ≤ 8

2*x/2 ≤ 8/2

x ≤ 4

Which is equivalent to 3 cube root 125

aleksklad [387]

Do you mean $3 \sqrt[3]{125}$ or $\sqrt[3]{125}$
remember that $\sqrt[n]{x^m}=x^\frac{m}{n}$
resolve the $\sqrt[3]{125}$ part first $\sqrt[3]{125}=$ $\sqrt[3]{5^3}=$ $5^\frac{3}{3}=$ $5^1=$ $5$

so
$3 \sqrt[3]{125}=3*5=15$ or $\sqrt[3]{125} =5$ not sure which one you mean

There is a proportional relationship between the volume of a sample of helium in liters and the mass of that sample in grams. if

love history [14]

Answer:

v = 5.6m

Step-by-step explanation:

Proportional relationship equation:

y = kx, where k- constant of proportionality

Use the given point to work out the value of k:

28 = 5k
k = 28/5
k = 5.6

In our case the equation is:

v = 5.6m, where v- volume, m- mass

The scatterplot shown includes the (blue) least-squares regression line, whose equation is y = .975 + .005x, where y is calories

ziro4ka [17]

The scatterplot shown includes the (blue) least-squares regression line, whose equation is y = .975 + .005x, where y is calories (in thousands) and x is years after 1960. Choose the correct statement.

Answer: In the given regression equation, the calories are in thousands. Therefore, the slope 0.005 (0.005 x 1000 =5 calories) means the consumption is increasing at a rate of 5 calories per year.

Hence the option a. Consumption is increasing at a rate of 5 calories per year. is correct

The owner of the Rancho Grande has 3,044 yd of fencing with which to enclose a rectangular piece of grazing land situated along

inysia [295]

Answer:

Step-by-step explanation:

Area of the rectangular piece A = xy

x is the length

y is the width

Perimeter =2x+2y

Given

Perimeter = 3044yds

3044 = 2x+2y

1522 = x+y

x = 1522-y

Substitute into the formula for area

A = xy

A = (1522-y)y

A = 1522y-y²

To maximize the area, dA/dy must be zero

dA/dy = 1522-2y

0 = 1522-2y

2y = 1522

y = 1522/2

y = 761

Since x+y = 1522

X+761 = 1522

X = 761

Dimension is 761yd by 761yd

Area = 761×761 = 579121yd²
