Write a SIMPLIFIED inequality for x that would give a rectangle with a length of 4 meters and a width of x+7 meters an area of m

Rashid [163]

Answer:

128 > 4*(x + 7)

Step-by-step explanation:

Given the following data;

Length = 4 meters

Width = x + 7 meters

Area = 128 m²

Mathematically, the area of a rectangle is given by the formula;

Area of rectangle = length * width

Substituting into the formula, we have;

128 > 4*(x + 7)

128 > 4x + 28

128 - 28 > 4x

100 > 4x

Dividing both sides by 4, we have;

25 > x

Algebra 1 Grade 9.

Leya [2.2K]

Answer:

627.65 times

2.51^(10 - m) times

Yes, it makes sense

Step-by-step explanation:

Given that,

A magnitude 9 star is 2.51 times as bright as a magnitude 10 star

To find

How many times as bright is a magnitude 3 star as a magnitude 10 star

10 - 3 = 7

2.51^7

627.65 times

Expression to compare a magnitude m star to a magnitude 10 star

2.51^(10 - m) times

Yes, it makes sense as a full moon is magnitude -13

so,

2.51^(10 - (-13))

2.51^(23)

1557742231 times

Marcie cooked dinner for herself. The original recipe has a serving size of 3 and requires three and three sevenths pounds of ch

Sati [7]

Using proportions, the number of pounds that will be needed for a single serving is: one and three seventh pounds.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of pounds for 3 people is given by:

$3 \frac{3}{7} = 3 + \frac{3}{7} = \frac{24}{7}$

Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:

$\frac{24}{7} \times \frac{1}{3} = \frac{24}{21}$

24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:

one and three seventh pounds.

Why is this binomial and what is the answer?

pashok25 [27]

Answer:

2e⁻² ≈ 0.271

Step-by-step explanation:

This is actually a Poisson distribution. The probability is:

P(x; μ) = e^(-μ) (μˣ) / x!

P(2; 2) = e⁻² (2²) / 2!

P(2; 2) = 2e⁻²

P(2; 2) ≈ 0.271
