Answer:

Step-by-step explanation:

The problem statement gives two relations between x (jars of jam) and y (packages of bread mix).

  6x +5y = 45 . . . . . . total cost

  x + y = 8 . . . . . . . . . number of items

__

These equations can be solved a number of ways. Substituting for y, we get ...

  y = 8 -x

  6x +5(8 -x) = 45

  x +40 = 45

  x = 5 . . . . . . . . . jam

  y = 8 -5 = 3 . . . mix

There are 5 jars of jam and 3 packages of bread mix in the gift basket.

Answer:

[tex]y = \frac{2}{3}x - \frac{4}{3} [/tex]

Step-by-step explanation:

first find the slope using the above points then use the slope formula to calculate the slope

[tex]m = \frac{y2 - y1}{x2 - x1} \\ \frac{2 - - 4}{5 - - 4} = \frac{2 + 4}{5 + 4} = \frac{6}{9} = \frac{2}{3} [/tex]

substitute ⅔ for m and one of the above points into the y-intercept form of the equation for a line and solve for b

[tex]y = mx + b \\ 2 = \frac{2}{3} (5) + b \\ 2 = \frac{10}{3} + b \\ 2 - \frac{10}{3} = b \\ \frac{6}{3} - \frac{10}{3} = b \\ b = - \frac{4}{3} [/tex]

substitute the slope and the value for b into the equation to get the answer

[tex]y = \frac{2}{3} x - \frac{4}{3} [/tex]

Answer:

$7.08

Step-by-step explanation:

59 cents = 1 sq ft

? = 12 sq ft

To get from the 1 to the 12 we multiply by 12, so we must do the same to the 59 cents.

0.59 * 12 = 7.08

Therefore, the cost of 12 sq ft is $7.08.

Step-by-step explanation:

Part A: The expression for the total number of minutes Mario volunteers each year at the animal shelter  =  (405/y)   x  365

Part B: The simplified form of the expression for the total number of minutes Mario volunteers each year at the animal shelter = (147825/y) minutes

Number of days Mario volunteers each month at the animal shelter = 1

Number of hours Mario cleans for y days = 5.5 hours

Number of hours Mario each day = 5.5/y

Number of minutes Mario uses to walk dogs for y days = 75 minutes

Number of hours Mario uses to walk dogs for y days=  75/60

Number of hours Mario uses to walk dogs for y days=  1.25 hours

Number of hours Mario uses to walk dogs each day= 1.25/y

Total number of hours Mario volunteers in a day = Number of hours Mario cleans each day + Number of hours Mario uses to walk dogs

Total number of hours Mario volunteers in a day = 5.5/y + 1.25/y

Total number of hours Mario volunteers in a day = 6.75/y

Convert the number of hours to minutes

1 hour   =  60 minutes

Total number of minutes Mario volunteers in a day = (6.75/y) x 60

Total number of minutes Mario volunteers in a day = (405/y) minutes

Number of days in 1 year = 365

The expression for the total number of minutes Mario volunteers each year at the animal shelter  =  (405/y)   x  365

The simplified form of the expression for the total number of minutes Mario volunteers each year at the animal shelter = (147825/y) minutes

Answer:

Out of 36 cubes on each face, the 16 cubes not on an edge are the only ones frosted on a single face. 16 on each face x 6 faces = 96 cubes frosted on one face.

Step-by-step explanation:

Hope it helps!

There are 64 cubes that are frosted on one side only.

"A Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges. It is also said to be a regular hexahedron."

"Shapes in three-dimensions or as we view them in real life are called 3D shapes. Examples of 3D shapes are cubes, cuboids, spheres, cylinders, cones and frustum of cones."

Each face will have three types of cubes on it:

1. Corner Cubes - Frosted on three adjacent sides

2. Edge Cubes - Frosted on two adjacent sides and on the edge between two corner cubes.

3. Central Cubes - Frosted on one side and in the middle of all edges of the face.

Thus, the number of cubes that have only one side as frosted are the total number of central cubes. They can be calculated as follows for all 6 faces:

[tex]Cubes_{central}[/tex] = (6−2)(6−2)+(6−2)(4-2)+(6−2)(4−2)+(6−2)(6−2)+(6−2)(4−2)+(6−2)(4−2)

= [tex]2 (4)^{2}+4(4)(2)[/tex]

= 32+ 32

= 64

Thus there are 64 cubes that are frosted on one side only.

Answer:

a = 3/4

Step-by-step explanation:

Given the vertex, (3, -1) and the other point, (5, 2):

We could substitute these values into the vertex form of the quadratic equation:

y = a(x - h)² + k

Where:

(h, k ) = vertex

a = determines whether the graph opens up or down, and makes the graph wider or narrower.  

h = determines how far left or right the parent function is translated.

k =  determines how far up or down the parent function is translated.

Substitute the vertex, (3, -1) and point (5, 2) into the vertex form to solve for "a":

y = a(x - h)² + k

2 = a(5 - 3)² - 1

2 = a(2)² - 1

2 = a(4) - 1

Add 1 to both sides:

2 + 1 = a(4) - 1 + 1

3 = 4a

Divide both sides by 4 to solve for a:

3/4 = 4a/4

3/4 = a

Therefore, the value of a = 3/4. Since the value of a is positive, and that it is between 0 and 1, then it means that the graph opens upward and is wider than the parent function.

The quadratic equation in vertex form is: y = 3/4(x - 3)² - 1, where a = 3/4.

Step-by-step explanation:

a diameter is always twice the radius.

the only pairs I can see in the list, where one number is twice the other :

2.5 and 5

7.6 and 15.2

so,

2.5 is the radius of A

5 is the diameter of A

7.6 is the radius of B

15.2 is the diameter of B

15.7 is then the circumference of A (as the smaller of the remaining 2 numbers)

47.7 is the circumference of B

we can also check via the formula for circle circumference :

c = 2×pi×r

and yes, the rounded c for r=2.5 is 15.7, and for r=7.6 is 47.7
