Your answer is correct.

For breakfast, the family decides to spend no more than $20.00 for the week.

Each day, the family drinks 2/7 of a liter of milk for breakfast.

For the entire week, the amount of milk consumed is

Milk costs $4,49 per liter, so the cost of the total amount of milk consumed is

So, the amount left for the granola is

Each day, the family eats 1/3 of a pound of granola for breakfast.

For the entire week, the amount of granola consumed is

Let x be the price per pound of the most expensive granola they can afford.

Therefore, the most expensive granola they can afford is $4.72

The unknown angles of the triangle and trapezium are as follows:

A triangle is a polygon with three sides.

The sum of angles in a triangle is 180 degrees.

Therefore, angle 1 can be found as follows:

∠1 = 180 - 40 - 30

∠1 = 180 - 70

∠1 = 110 degrees.

Therefore, angle 2 can be found as follows:

∠2 = 180 - 40 - 40 - 30 - 30

∠2 = 180 - 80 - 60

∠2 = 180 - 140

∠2 = 40 degrees.

A quadrilateral is a polygon with 4 sides. The sum of angles in a quadrilateral is 360 degrees.

Therefore, the triangle in the trapezium is an isosceles triangle. The base angles are equal.

Hence,

∠1 = 180 - 30 - 30

∠1 = 180 - 60

∠1 = 120 degrees

Sum of angles in the same transversal is supplementary.

Therefore,

90 + 30 + ∠2 = 180

∠2 = 180 - 120

∠2 = 60 degrees

Answer:

13 ⅓.

Step-by-step explanation:

The area of a rectangle is given by

Area = Length × Breadth

Length = 2 7/9 = 25/9 and breadth = 4 4/5 = 24/5

.: Area = 25/9 × 24/5 = 600/45 (15 can go to both the numerator and denominator)

We have 40/3 but to convert it to a mixed fraction we get 13 ⅓ as your area.

answer:

the y-intercept is 15 which is the initial total depth of the snow at t=0 hours.

The rate of melting is 1.5inches per hour. It will take 10 hours at the melting rate given of 1.5 to melt all the snow.

Step-by-step explanation:

the y-intercept is 15, and it might mean that the total depth of the snow is 15 inches.

The rate of melting is 1.5inches per hour.

At time = 0, S=15 - 1.5t = 15 - 1.5(0) = 15 inches to start

At time = 10, S=15 - 1.5t = 15 - 1.5(10) = 0 inches; meaning all snow has melted and it took 10 hours.

A) g(x)= (x-5)(x-9)

This is the answer because basically you need to find the roots of the function, since the function g intersects the x-axis at x=5 and x=9 you can conclude easily that those are the roots.

x=5

g(5)=(5-5)(5-9)=0(-4)=0

and

If:

Step-by-step explanation:

If Zeke learned that he could earn another $2000 a year if he become fluent in Spanish and he intended to learn the language and work another 10 years at that job, then the amount is learning Spanish worth to him is $20000

The extra amount he could make if he learn Spanish = $2000

The number of years he works = 10 years

To find the extra amount, we have to use multiplication

The extra amount he could make if he learn Spanish = The extra amount he could make if he learn Spanish × The number of years he works

Substitute the values in the equation

= 2000×10

Multiply it

= $20000

Hence, if Zeke learned that he could make another $2000 a year if he become fluent in Spanish and he intended to learn the language and work another 10 years at that job, then the amount is learning Spanish worth to him is $20000

Step-by-step explanation:

a rational number is any number that can be written as a fraction or a decimal that does not go on forever (unless it is a repeating decimal, ex: 3.454545..)

The equation of the line perpendicular to the line −7x+2y=3 having the same y-intercept as 9x+3y=−2 is  y = - 2 / 7x - 2 / 3

The equation of a line can be represented as follows:

y = mx + b

where

Therefore, the equation of the line is perpendicular to  −7x+2y=3.

−7x+2y=3

2y = 7x + 3

y = 7 / 2 x + 3 / 2

Perpendicular lines follows the rule below:

m₁ m₂ = -1

7 / 2 m₂ = -1

7m₂ = -2

m₂ = - 2 / 7

Therefore, the equation of the line also haver the same y-intercept as

9x + 3y = −2.

3y = - 9x  - 2

y = -3x - 2  /3

The y-intercept of the equation is - 2 / 3.

Hence

the equation of the line is y = - 2 / 7x - 2 / 3

The equation of the line will be equal to 3y = -x + 21.

A line may be defined as the straight figure drawn which has no end points. The equation of a line can be written in slope intercept form as y = mx + c where m is the slope of line, c is y intercept an x and y are independent and dependent variables. If a point (x₁, y₁) is given then equation of line is (y - y₁) = m (x - x₁). The slope of line which is perpendicular to a given line having slope m is equal to -1/m.

Now, equation of line is y = 3x + 3. If we compare with slope intercept form then, m = 3. Now, slope of line perpendicular to this line is equal to -1/3. Now, equation of line passing through point (-6, 9) is given as

(y - 9) = -1/3 (x + 6)

3y - 27 = -x - 6

=> 3y = -x + 21 which is the required equation of line.

Cos(0) = - 0.949 this expression is accurate for the unit circle which is intersected at point by angle 8 according at point (-0.949, 0.314).

An elliptical plane figure is a circle. From a fixed location known as the circle's center, each point on the circle is equally distant. It has a two-dimensional (2D) shape and a radius value. The Latin word "circulus" (which means little ring) is the root of the English word "circle."A circle is a two-dimensional shape that is made up of a collection of points that are spaced out from the center of the circle (its fixed point) on the plane by a fixed or constant distance (radius). The radius of a circle is the fixed distance between points that is fixed from the fixed point, which is known as the origin or center of the circle.

The terminal side of angle 0 intersects the unit circle at point P(- 0.949, 0.314) That means, OQ = 0.949 and PQ = 0.314

Here, OP is the radius of the unit circle. So, OP = 1

In respect of angle 0, the adjacent side is OQ and the hypotenuse is OP.

We know that,

cos= [tex]\frac{adjacent}{hpotenusey}[/tex]

So,

cos(0) = - [tex]\frac{OQ}{OP}[/tex]  [As the angle is in quadrant II, so cos is negative]

cos(0) = - [tex]\frac{-0.949}{1}[/tex]

cos(0) = - 0.949

Cos(0) = - 0.949 this expression is accurate for the unit circle which is intersected at point by angle 8 according at point (-0.949, 0.314).

Find f(x) when x = 2

y = 1 / 3 x + 5 is the linear equation for the first table.

The system of equations' answer is (3, 6).

A linear equation is an algebraic equation of the form y= mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The previous equation, which has the variables y and x, is sometimes referred to as a "linear equation with two variables."

based on the available facts;

Equation of a point slope:

y = mx + b,

where m = slope and b = y-intercept

As a result, the equation for the second table is y = - 1 /3 x + 7.

With the help of the table's (0, 5)(3, 6) values, the equation for the first table may be solved. Therefore,

m = 6 - 5 / 3 - 0 = 1 / 3

let's find b using (0, 5)

5 = 1 / 3(0) + b

b = 5

Therefore, the equation of the first table is as follows:

y = 1 / 3 x + 5

The solution to the system of equation can be calculated as follows:

y + 1 /3 x  = 7

y - 1 / 3 x  = 5

2y = 12

y = 12 / 2

y = 6

6 - 1 / 3 x = 5

- 1 / 3 x = 5 - 6

- 1 / 3 x = - 1

x = 3
