The number of oatmeal cookies when Brenda ordered 12 dozen cookies from the bakery is 18.

Since Brenda ordered 12 dozen cookies from the bakery, the total number ordered will be:

= 12 × 12

= 144 cookies

Since 1/3 of them or peanut butter 1/6 of the cookies are ice 3/8 of the cookies are chocolate, the fraction for oatmeal will be:

= 1 - (1/3 + 1/6 + 3/8)

= 1 - 7/8

= 1/8

The oatmeal cookies will be:

If Triangles ABC and DEF are similar. Side length AB is 2, side length AC is 4, and side length BC is 3 Side length DE is 1.34 then  length of  DF = 2.68 and length of  EF = 2.01

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Given,

Triangles ABC and DEF are similar.

AB = 2

AC = 4

BC = 3

DE = 1.34

We need to find the length of DF and EF

Given that ABC and DEF are similar, therefore:

AB/DE = BC/EF = AC/DF

2/1.34=3/EF=4/DF

1.49=3/EF=4/DF

Now,

1.49=3/EF

EF=3/1.49

EF=2.01

1.49=4/DF

DF=4/1.49

DF=2.68

Hence, length of  DF = 2.68 and length of  EF = 2.01

The distance each player ran for warm up laps is 875 cm and the distance each player ran for the store is 1.47 meters.

According to the question,

We have the following information:

Adrianna’s football team ran some warm up laps with a total distance of 6125 centimeters. There are 7 players on her football team.

The distance to the store = 10.31 meters

Now, we can find the distance ran by each player by dividing the total distance by number of players.

Distance for warm up laps = 6125/7

Distance ran by each player = 875 cm

Distance for the store = 10.31/7

Distance for the store = 1.47 m

Hence, the distance each player ran for warm up laps is 875 cm and the distance each player ran for the store is 1.47 meters.

3589.9 m is the height at which air pressure equals 65% of the air pressure at the surface of the Earth

Given: the function P(h) =P₀ e^(-0.00012h)

When air pressure equals 65% of the air pressure at the surface of the Earth. That means P = 0.65P₀

Substitute P = 0.65P₀ into the function:

P(h) = P₀ e^(-0.00012h)

0.65P₀  = P₀ e^(-0.00012h)

Dividing both sides by P₀ gives:

0.65  = e^(-0.00012h)

Take ln of both sides (ln is the inverse of e):

ln 0.65 = -0.00012h

h = ln 0.65/ (-0.00012)

h = 3589.9 m

Therefore, the height at which air pressure equal 65% of the air pressure at the surface of the Earth is 3589.9 m. Option D is the answer

So, she has a total of 4 books in her book shelf.

So, the number of positions in which the books have to be put are four.

As we can see,

The books are only one in number each. So, the choices are not repeatable.

So,

In first position we have four choices, in third we will be left with three choices, in the seconds position we will have a total of two books as choice and in the last positive we have to put the book that is left.

Equation of line having passing points (-6,0) and (0,-24) is 4x + y + 24 = 0

What do you mean by equation of line?

The general equation for every straight line is y = mx + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y-axis).

The variables x and y are related to coordinates on the line in the linear equation y = mx + c.

The formula y = mx + c yields a result for y when we enter a value for x.

As y depends on the value of x, it follows that x is an independent variable and y is a dependent variable.

Two passing points of line are (-6,0) and (0,-24)

Equation of line having two passing points as (a,b) and (c,d) is

[tex](y-b) = \frac{d-b}{c-a} (x-a)[/tex]

So, here equation of line become ,

[tex](y - 0) = \frac{-24-0}{0+6}(x+6)[/tex]

⇒ [tex]y = \frac{-24}{6}(x+6)[/tex]

⇒ y = -4(x+6)

⇒ y = -4x - 24

⇒ 4x + y + 24 =0

Hence, equation of line having passing points (-6,0) and (0,-24) is 4x + y + 24 = 0

Answer:

Step-by-step explanation:

You want to know the values of x and y that make the angle measures consistent with the triangles being congruent in the given figure.

The side markings show congruent triangles with corresponding vertices (and angles) ...

  L (3x+24)° ⇔ P (8x -11)°

  M 84° ⇔ Q 84°

  N (2x +y)° ⇔ R (no marking)

Corresponding angles L and P have the same measure, so ...

  3x +24 = 8x -11

  35 = 5x . . . . . . . . add 11-3x

  7 = x . . . . . . . . . divide by 5

The measures of these angles are ...

  (3(7) +24)° = 45°

The sum of the angles in each triangle is 180°, so the measure of angle N is found to be ...

  L +M +N = 180°

  45° +84° +N = 180°

  N = 51°

This lets us find the value of y from ...

  (2x +y)° = 51°

  2(7) +y = 51

  y = 37 . . . . . . . . subtract 14

The value of x is 7. The value of y is 37.
