The answer is A.

5 × 6 = 30
4 × 5 = 20
30 - 20 = 10

so there are ten more red apples so A is the answer

The numbers of calories per serving for various snakes foods are listed below.

Elanso [62]

Answer:

B. 108 calories

Step-by-step explanation:

The mean number of a data set is

$\text{Mean}=\dfrac{\text{The sum of all calories in products}}{\text{The number of products}}$

Corn chips: 230 calories

Popcorn: 25 calories

Potato chips: 115 calories

Pretzels: 62 calories

Thus,

The sum of all calories $=230+25+115+62=432$

The number of productrs = 4

The mean number of calories $=\dfrac{432}{4}=108$

Line segment AB has endpoints A(3, -7) and B(-9,-5). Find the equation of the perpendicular bisector

kupik [55]

Answer:

y = 6x + 12

Step-by-step explanation:

We require the midpoint M and slope of AB

Using the midpoint formula, then

M = [ $\frac{1}{2}$ (3 - 9) , $\frac{1}{2}$ (- 7 - 5) ] = (- 3, - 6 )

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = A(3, - 7) and (x₂, y₂ ) = B(- 9, - 5)

m = $\frac{-5+7}{-9-3}$ = $\frac{2}{-12}$ = - $\frac{1}{6}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-\frac{1}{6} }$ = 6

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 6 , thus

y = 6x + c ← is the partial equation

To find c substitute M(- 3, - 6) into the partial equation

- 6 = - 18 + c ⇒ c = - 6 + 18 = 12

y = 6x + 12 ← equation of perpendicular bisector

Hey, I would appreciate it if you can help me with these problems, been stuck on it for a few days

Makovka662 [10]

Answer:

Explained below.

Step-by-step explanation:

The formula for average rate of change is:

$\frac{f(b) - f(a)}{b - a}$

1. $\frac{f(b) - f(a)}{b - a}$ = $\frac{f(2) - f(1)}{2 - 1}$ = $\frac{100 - 40}{2 - 1}$ = $\frac{70}{1}$ = 70

2. $\frac{f(b) - f(a)}{b - a}$ = $\frac{f(4) - f(2)}{4 - 2}$ = $\frac{180 -110}{4 - 2}$ = $\frac{70}{2}$ = 35

3. $\frac{f(b) - f(a)}{b - a}$ = $\frac{f(8) - f(6)}{8 - 6}$ = $\frac{350 -230}{8 - 6}$ = $\frac{120}{2}$ = 60

4. $\frac{f(b) - f(a)}{b - a}$ = $\frac{f(10) - f(8)}{10 - 8}$ = $\frac{390 -350}{10 - 8}$ = $\frac{40}{2}$ = 20

5. Their average speed was the greatest during the first to second hour.

6. Their average speed was the least during the eight to tenth hours.

7. $\frac{f(b) - f(a)}{b - a}$ = $\frac{f(10) - f(1)}{10 - 1}$ = $\frac{390 -40}{10 - 1}$ = $\frac{350}{9}$ = 38.89 or 38.9

Hope that helps!
