Answer:

Option A

Step-by-step explanation:

Step 1:  Solve the equation

[tex]2x + 5 \geq 15[/tex]

[tex]2x + 5 - 5 \geq 15 - 5[/tex]

[tex]2x \geq 10[/tex]

[tex]2x / 2 \geq 10/2[/tex]

[tex]x \geq 5[/tex]

Step 2:  What model represents the equation

Seems like option A represents the best because it showcases 2 x's and 5 +1's on the left side which is then greater or equal to the right side with 10 +1's.

Answer:  Option A

First, subtract 5 on both sides

2x≥15-5

2x≥10

Now divide by 2 on both sides

x≥5

-2ln + 2mn

Step-by-step explanation:

Simplify l(m-n) + m(n-l) + n(m-l)​

Step 1 : Distribute and multiply

l(m-n) + m(n-l) + n(m-l)​

l(m) + l(-n) + m(n) + m(-l) + n(m) + n(-l)

lm - ln + mn - lm + mn - ln

Step 2: Combine like terms

lm - ln + mn - lm + mn - ln

lm - lm - ln - ln + mn + mn

0 -2ln + 2mn

Solution:

-2ln + 2mn

Answer:

new width=9.375 in

new scale= 1 foot= 0.4 inches

Step-by-step explanation:

Firstly to find the width we can set up a proportion:

[tex]\frac{x}{15}[/tex] =[tex]\frac{6}{9.6}[/tex], after solving for x, x= 9.375, which gives us our width.

To find the new scale, we knew that the old scale was 2 in=5 feet, or 1 in=2.5 feet, so to find the new one we can also set a new proportion,

[tex]\frac{1}{2.5} = \frac{15}{x}[/tex]

After solving you will get x= 37.5, so 15 inches= 37.5 feet, but to simplify we can divide,

15/37.5= 0.4

Answer:

The total number of caramel apples are covered with sprinkles is 20 and this can be determined by using the arithmetic operations.

Step-by-step explanation:

Given :

Maya has 120 caramel apples to sell. Each caramel apple is covered with one topping.

1/5 of the caramel apples are covered with peanuts.

1/3 of the caramel apples are covered with chocolate chips.

3/10 of the caramel apples are covered with coconut. The rest are covered with sprinkles.

The following steps can be used in order to determine the total number of caramel apples are covered with sprinkles:

Step 1 - The arithmetic operations can be used in order to determine the total number of caramel apples are covered with sprinkles.

Step 2 - Let 'n' be the number of caramel apples are covered with sprinkles.

Step 3 - So, the value of 'n' is calculated as:

Step 4 - Simplify the above equation.

120 = 24 + 40 + 36 + n

n = 20

Answer:

There are 20 caramel apples that are covered with sprinkles.

Step-by-step explanation:

First we should make all of these have a common denominator. We could make these be 1/5 = 6/30, 1/3 = 10/30, 3/10 = 9/30. Now we can add them all up. 6 + 10 + 9 = 25/30. Now, to figure out how many apples is 1/30. 120 divided by 30 = 4. Now we can do 4x25 because that's how many non sprinkle apples there are. This is 100. 120 - 100 = 20. You could have also done 4x5 because there were 5/30 sprinkle apples, and gotten the same answer.

       so, there are 20 caramel apples that are covered with sprinkles.

Answer:

x = 10; y = 6

Step-by-step explanation:

Let's list the factors of 60 because the product of those numbers is 60.

The following possibilities of x and y are possible using (x × y = 60):

Let's check each possibilities using the equation (x - y = 4):

Thus, the values of x and y are 10 and 6 respectively.

x²=11+2

x²=13

x=√13 ans…

Step-by-step explanation:

f(-1) = 4(2)^-1 ≈ 4 × 1/2 = 2

(x, f(x)) = (-1, 2)

f(0) = 4(2)⁰ = 4×1 = 4

(x, f(x)) = (0, 4)

f(1) = 4(2)¹ = 4×2 = 8

(x, f(x)) = (1, 8)

f(2) = 4(2)² = 4×4 = 16

(x, f(x)) = (2, 16)

Answer:

Choice C

Step-by-step explanation:

This is like a matching question. Here's what I mean by this. We know Triangle BCA and Triange JKL are congruent. So, what we have to do is match the side lengths together.

So the first side of BCA matches with JKL, the second side of BCA matches with JKL, the third side of BCA matches with JKL.

So first side:

BC is congruent  to JK

So second side:

CA is congruent  to KL

So third side:

JL is congruent  to BA

The third side is one of our answer choices.

That answer choice is C.

A guideline is a statement by which to determine a course of action. A guideline aims to streamline particular processes according to a set routine or sound practice. 

The triangles ABC and EDC have corresponding sides

The triangles ABC and EDC are similar

The given parameters are:

ED = 8, DC = 10, EC = 12, AB = 12

BC = 15 and AC = 21

To determine that the triangles are similar, we simply divide the corresponding sides to determine the scale factor (k).

So, have:

k = AB/ED = BC/DC

This gives

k = 12/8  = 15/10

Evaluate the quotients

k = 1.5 = 1.5

The scale factors are equal

Hence, the triangles ABC and EDC are similar

Mode = 6

Range = 7

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

Explanation:

The mode is the most frequent value. Based on that, we simply go for the tallest stack of 'x's which in this case is 6.

Therefore, 6 is the mode. It shows up four times which is the most of any other value.

-------

The range is the difference of the min and max

range = max - min = 8 - 1 = 7

Answer:

Step-by-step explanation:

When your desired form is expanded, it becomes ...

  a(x +b)^2 = a(x^2 +2bx +b^2) = ax^2 +2abx +ab^2

This tells you the overall factor (a) is the leading coefficient of the given trinomial. Factoring that out, you can find b as the root of the remaining constant.

a) 5x^2 +15x +11.25 = 5(x^2 +3x +2.25) = 5(x +1.5)^2

b) 10x^2 +20x +10 = 10(x^2 +2x +1) = 10(x +1)^2

c) 1/4x^2 +x +1 = 1/4(x^2 +4x +4) = 1/4(x +2)^2

d) 3x^2 +5x +25/12 = 3(x^2 +5/3x +25/36) = 3(x +5/6)^2

_____

Additional comment

If you know beforehand that the expressions can be factored this way, finding the two constants (a, b) is an almost trivial exercise. It gets trickier when you're trying to write a general expression in vertex form (this form with an added constant). For that, you must develop the value of b from the coefficient of the linear term inside parentheses.

and you cut it in half.

There are three sides

Answer:

Step-by-step explanation:

The cut pieces will each have three sides:  two that are equal and one that is the hypotenuse.

If the original square had sides of length s, then the cut pieces would each have two of that length:  s and s; the third side would have length h = √(s² + s²), or h = s√2.
