patriot [66]

Answer:

The required inequalities are s+g\leq 30 and s>7.

Step-by-step explanation:

Consider the provided information.

Daniel moves no more than 30 of his sheep and goats into another field.

Let s represent the number of sheep and g represent the number of goats.

No more than means the number of sheep and goats should be less than or equal to 30.

For less than or equal to use the inequality ≤

Hence the required inequality is: s+g\leq 30

More than 7 of his animals are sheep.

This can be represented as:

s>7

Hence, the required inequalities are s+g\leq 30 and s>7.

The two-way table shows the number of people ages 20 and 50 who belong to Group A or B.
BabaBlast [244]
If what you mean by the "percent of people 50 years old belong to group A" is the percentage of 50-year old people with respect to the total number of people belonging to group A, then the answer is

32/(19+32) * 100 = 63%

But, if what you mean is the percentage of 50-year old people in group A with respect to the total number of 50-year old people, then the answer will be

32/(32+24) * 100 =  57%

Which of the following answer choices is an equation for the circle with a center of (-2, 3) and a radius of 3?
mamaluj [8]

Answer:

A

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 2, 3) and r = 3 , then

(x + 2)² + (y - 3)² = 9 ← expand left side using FOIL

x² + 4x + 4 + y² - 6y + 9 = 9  ( subtract 9 from both sides )

x² + y² + 4x - 6y + 4 = 0 → A

165/1.5

= 110

This means that the speed of the train is 110 km per hour.

So, the constant of variation is 110.
