Answer:

1. $16

2.$61.75

3. $222

4.$130

Step-by-step explanation:

1.     20% of $20 is $4.

$20-$4=$16

2.    35% of $95 is $33.25.

$95-$33.25=$61.75

3.    $55.50 divided by 1-.75=222

4.     $78 divided  by 1-.40=130

Hope this helped :)

A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).

The 2 and + are out since they don't have variables(and the + is just a +).

So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.

The function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Given that, Amir has 48 ounces of cashews, walnuts, and pecans.

He adds x ounces of peanuts to create a mixture.

M(x) that represents the number of ounces of all nuts in the mixture.

M(x)=48

N(x) that represents the number of ounces of peanuts in the mixture.

So, N(x)=x

Now, (M/N)(x) = M(x)/N(x)

= 48/x

Therefore, the function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.

Answer:

The two triangles can be considered similar as Angle A is 70 degrees and Angle B is a congruent angle to Angle A, which can be proven by adding 70 to 110 which shows a 180 degree angle (flat angle). Therefore we know that this triangle is similar

Step-by-step explanation:

Answer:

1 ÷ 2 pounds

Step-by-step explanation:

The computation is shown below:

As we know that

1 pound = 0.454 Kg

Peanut starting weight = 3 ÷ 4 of a pound.

In the case when  the bag is 2/3 full, so the weight is  

= 2 ÷ 3 × 3 ÷ 4

= 1 ÷ 2 pounds

Answer:

11 up , 11 left

Step-by-step explanation:

Given

[tex](17, -9)[/tex] to [tex](6,2)[/tex]

Required

Determine the translation rule

Considering the x coordinates.

From 17 to 6

6 is to the left of 17.

Using the translation rule:

[tex]x = x' + b[/tex]

[tex]17 = 6 + b[/tex]

[tex]17 - 6 = b[/tex]

[tex]11 = b[/tex]

[tex]b = 11[/tex]

Hence: From 17 to 6 is 11 units left translation

Considering the y coordinates.

From -9 to 2

2 is at the top -9.

Using the translation rule:

[tex]y = y' + b[/tex]

[tex]-9 = 2 + b[/tex]

[tex]-9 - 2 = b[/tex]

[tex]-11= b[/tex]

[tex]b = -11[/tex]

The negative value impies a upward translation.

Hence: From -9 to 2 is 11 units up translation

The third equation

Answer:

Slope intercept form is y = mx + b

m is slope

b is y intercept

y = -4/5x + -9

I only know that first one sry

Step-by-step explanation:

Answer:

yes.

Step-by-step explanation:

slope intercept form is y=mx+b

b is the y intercept, m is the slope, and x is x.

for

1. it would be

y= -4/5x -9

2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)

it would look like:

(5- -3) / (3-0) = (8/3)

Then plug in one of the sets of numbers for x and y, to get y intercept.

5=8/3(3)+b

b=-3

So.. slope intercept would be y=8/3x -3

What is the other number and do you have like a picture

Answer:

y= -3x+2

Step-by-step explanation:

Answer:

area = m²/2π

Step-by-step explanation:

∵ circumference of circle = 2πr = m

∴ r = m/2π

∵ area of circle = πr²

∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π

3 3/5 of a punnet of strawberries(mixed Number)

Step-by-step explanation:

Mimi = 9/10 of a punnet of strawberries

Jamie has four times as many strawberries as Mimi

Jamie = 9/10 × 4

= (9×4) / 10

= 36/10

= 3 6/10

= 3 3/5 of a punnet of strawberries

Jamie = 3 2/5 of a punnet of strawberries
