A company figured it needed 68. 5 square feet of carpet for its reception room. To allow for waste, it was decided to order 40 percent more material than needed. Fractional parts of square feet cannot be ordered. At $8. 00 per square foot, how much would the carpet cost?

Answers

The total cost of the carpet purchased by the company for its reception is $767.20.

What is the total cost of the carpet?

The first step is to determine the total square feet of carpet that would be bought: 1.40 x 68.5 = 95.9 square feet

Now, determine the total cost of the carpet. This can be known by multiplyig the cost per square foot by the total amount of carpet needed.

95.9 x 8 = $767.20

A bagel costs $2.15 and cream cheese
costs $0.75. If you buy milk for $2.00, is
$5.00 enough to cover the cost of all
items? Explain.

Answers

Answer:

Yes

Step-by-step explanation:

You do have enough money because 2.15+0.75+2.00 is = to 4.90 and we know that 4.90 is less than 5.00

Yes, because the total cost would be $4.90. If you pay with a 5 dollars bill then you would have $0.10 left over after you have purchased all those items
$2.15 + $0.75 = $2.90
$2.90 + $2.00 = $4.90

Answer: Use the distance formula to find the length of each side, and then add the lengths.

Step-by-step explanation:

To find the perimeter of this quadrilateral with known vertices: Use the distance formula to find the length of each side, and then add the lengths.

What is distance?

The distance between two points is the length of the line joining the two points. Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.

Here, we have,

Mathematically, the distance between points on a coordinate plane is given by this formula:

Formula: distance= √(x_2-x_1)²+(y_2-y_1)²

Where:

x and y are the vertices (points) on a coordinate plane.

Therefore, when the distance formula has been used to determine the length of of each side of the quadrilateral. You should then add the lengths of each side together.

This one is about rate of change and has 2 questions that need two answers.

At 6:00 am, there was 1 inch of snow on the ground. By 11 am, there were 4 inches of snow on the ground. What is the average rate of change?

If the snow continues to fall at the same rate, how much snow will be on the ground by 1:00 pm.

Answers

Answer:

0.6 inches per hours

5.2 inches on the ground by 1:00 pm

Step-by-step explanation:

Let x = number of hours after midnight

Let y = height of snow (in inches)

Information presented as ordered pairs (x, y):

(6, 1)

(11, 4)

[tex]\mathsf{rate \ of \ change=\dfrac{change \ in \ y}{change \ in \ x}=\dfrac{4-1}{11-6}=\dfrac35 \ inches \ per \ hour}[/tex]

Written as a linear equation:

[tex]y-1=\dfrac35(x-6)[/tex]

[tex]\implies y=\dfrac35x-\dfrac{13}{5}[/tex]

1:00 pm = 13 hours after midnight

Therefore, when x = 13:

[tex]\implies y=\dfrac35(13)-\dfrac{13}{5}[/tex]

[tex]\implies y=5.2 \textsf{ inches}[/tex]

Box C contains Ray B C bisects angle A B D.

Answers

Answer:

Given that m∠ABC = m∠CBD, and m∠ABD = m∠ABC + m∠CBD BC bisects m∠ABD (Definition of angle bisector)

Step-by-step explanation:

The given information are;

m∠ABC = m∠CBD

To prove that Ray BC bisects m∠ABD

The description is therefore;

Three lines (AB, BC, and BD) that meet at a point

The content of Box A = m∠ABC = m∠CBD

The content of Box B = m∠ABC ≅ m∠CBD

The content of Box C = Ray BC bisects m∠ABD

Therefore, we have;

m∠ABD = m∠ABC + m∠CBD (Angle addition postulate)

m∠ABC = m∠CBD (Given)

∴ m∠ABC ≅ m∠CBD (Definition of congruent angles)

m∠ABC is adjacent to m∠CBD (Description of the angles)

Line BC is common to m∠ABC and m∠CBD (Description of the angles)

Therefore, given that m∠ABC = m∠CBD, and m∠ABD = m∠ABC + m∠CBD BC bisects m∠ABD (Definition of angle bisector).

A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. 'When the
rock is cut in half, what is the volume and density of each piece?

Answers

Answer:

Volume= 4 cm³

Density= 2 g/cm³

Step-by-step explanation:

We have the following data:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³

Answer:

x = -3/2

Step-by-step explanation:

We make both numbers have the same bases.

We know 2^4 = 16 and 2^-6 = 1/64 because a negative exponent means you get the reciprocal of the number.

2^4x = 2^-6

Let exponents equal each other.

4x = -6

Answers

Answer: Below

Step-by-step explanation:

Using the information, we can see that they all refer to Elena as a marker for how much they walked, directly or indirectly.

Let's use E for Elena, J for Jada, and L for Lin.

E + 4 = J

E + 6 = L

E = E

We know they all walked a total of 37 miles.

J + L + E = 37

(E + 4) + (E + 6) + E = 37

Simplify.

3E + 10 = 37

3E = 27

E = 9

Using E is 9, we find that:

Elena walked 9 miles

Lin walked 15 miles

Jana walked 13 miles

13 + 15 + 9 = 37, so our answer checks out.

Solution:

We know that:

[tex]Jada + Elena + Lin = 37 \space\ miles[/tex][tex]Jada = 4 + Elena[/tex][tex]Lin = 2 + Jada[/tex]Finding the distance each walked:[tex]Jada + Elena + Lin = 37 \space\ miles[/tex]

Add 4 both sides

=> [tex]Jada + Elena + 4 + Lin = 37 + 4[/tex]=> [tex]Jada + Jada + Lin = 41 \space\ miles[/tex] [tex][Jada = 4 + Elena][/tex]=> [tex]Jada + Jada + Jada + 2 = 41 \space\ miles[/tex] [tex][Lin = Jada + 2][/tex]

Changing "Jada + Jada + Jada" to "3(Jada)"

=> [tex]3(Jada) + 2 = 41 \space\ miles[/tex]

Subtracting 2 both sides:

=> [tex]3(Jada) = 41 - 2[/tex]=> [tex]3(Jada) = 39 \space\ miles[/tex]

Divide 3 both sides:

=> [tex]3(Jada) = 39 \space\ miles[/tex]=> [tex]\frac{3(Jada)}{3} = \frac{39 \space\ miles}{3}[/tex]=> [tex]\bold{Jada} = \bold{13 \space\ miles}[/tex]

Substituting the miles Jada walked into the equation "Jada = 4 + Elena"

[tex]Jada = 4 + Elena[/tex]=> [tex]13 = 4 + Elena[/tex]

Subtract 4 both sides:

=> [tex]13 - 4 = 4 - 4 + Elena[/tex]=> [tex]\bold{Elena} = \bold{9 \space\ miles}[/tex]

Substituting the miles Jada walked into the equation "Lin = 2 + Jada"

=> [tex]Lin = 2 + 13[/tex]=> [tex]\bold{Lin} = \bold{15 \space\ miles}[/tex]
