Which Graph Could Be Used To Show The Situation Described?the Temperature Decreases By 0.5 Degrees Every

Answers

Answer 1

Answer:

Option (2) [Graph on the top right]

Step-by-step explanation:

To find the temperature decrease by 0.5 degrees every hour we will find the slopes of the lines given in every option.

Option (1) [Top left graph]

Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

          = [tex]\frac{-20}{2}[/tex]

          = -10

Option (2) [Top right]

Slope = [tex]\frac{-2}{4}[/tex]

          = -0.5

Option (3) [Bottom left]

Slope = [tex]\frac{-2}{2}[/tex]

          = -1

Option (4) [Bottom right]

Slope = [tex]\frac{-60}{5}[/tex]

          = -12

Therefore, Graph given in option (2) will represent the decrease in temperature by 0.5 degrees per hour.

A collection of nickels and dimes is worth $4.40. There are 53 coins in all. How many
nickels are there?
12
18
35
41

Answers

A Nickel is worth 5 cents or 0.05.
A Dime is worth 10 cents or 0.10

n + d = 53
0.05n + 0.10d = 4.40

n = 53 - d
0.05(53 - d) + 0.10d = 4.40
2.65 - 0.05d + 0.10d = 4.40
0.05d = 4.40 - 2.65
0.05d = 1.75
d = 1.75 / 0.05
d = 35

n = 53 - d
n = 53 - 35
n = 18

There are 18 nickels and 35 dimes.

0.05n + 0.10d = 4.40
0.05(18) + 0.10(35) = 4.40
0.90 + 3.5 = 4.40
4.40 = 4.40

The number of nickels there should be considered as the 18 when the collection is to be given.

Calculation of the number of nickles:Since

A collection of nickels and dimes is worth $4.40. There are 53 coins in all.

So here we assume that

A Nickel is worth 5 cents or 0.05.

A Dime is worth 10 cents or 0.10

Now

n + d = 53

0.05n + 0.10d = 4.40

So, it can be like

n = 53 - d

0.05(53 - d) + 0.10d = 4.40

2.65 - 0.05d + 0.10d = 4.40

0.05d = 4.40 - 2.65

0.05d = 1.75

d = 35

Now

n = 53 - d

n = 53 - 35

n = 18

hence, The number of nickels there should be considered as the 18 when the collection is to be given.

How large is the yard?
square feet

James is thinking about extending the house by adding 2 feet to the length and 2 feet to the width.

How much area is now left for the yard?
square feet

Answers

Answer:

32 square feet20 square feet

Step-by-step explanation:

Given

The dimensions of the lot are (6+x) feet and (6−x) feetThe dimensions of the house to be (2+x) feet and (2−x) feet

Area of the yard = Area of the lot - Area of the house

Area of the yard:

(6 + x)(6 - x) - (2 + x)(2 - x) =36 - x² - 4 + x² =32 square feet

If the house is extended, then the area of the yard will change as:

(6 + x)(6 - x) - (4 + x)(4 - x) =36 - x² - 16 + x² =20 square feet

How many edges does the polyhedron have? 3 5 6 10

Answers

There are 4 faces, 6 edges and 4 vertices

The number of edges in a polyhedron cannot be determined without additional information about the shape of the polyhedron.

What is a polyhedron?

A polyhedron is expressed in a three-dimensional solid object that has flat faces, straight edges, and sharp corners or vertices.

It is not possible to determine the number of edges in a polyhedron based on the given information alone. The number of edges in a polyhedron depends on the specific shape of the polyhedron, as well as the number of faces and vertices it has.

For example, a tetrahedron has 4 triangular faces and 4 vertices, and each vertex is connected to three edges, so it has a total of 6 edges. On the other hand, an icosahedron has 20 triangular faces and 12 vertices, and each vertex is connected to five edges, so it has a total of 30 edges.

Therefore, the number of edges in a polyhedron cannot be determined without additional information about the shape of the polyhedron.

Mr. Young is offered an investment opportunity. Kyra says she will invest his money at a 6% simple interest rate over the next 7 years. Mr. Young decides to invest $3000. How much interest will he have earned when the investment matures? *

Answers

Answer:

$126

Step-by-step explanation:

Given that:

Investment is done as per Simple interest.

Principal = $3000

Time for which the investment is to done = 7 years

Rate of interest = 6%

To find:

Interest earned when the investment matures?

Solution:

Formula for Simple Interest :

[tex]Simple\ Interest = \dfrac{PRT}{100}[/tex]

Where [tex]P[/tex] is the principal amount

[tex]R[/tex] is the Rate of Interest

[tex]T[/tex] is the time for which the investment is made

Putting the given values:

[tex]Simple\ Interest = \dfrac{3000\times 6\times 7}{100}\\\Rightarrow Simple\ Interest = \dfrac{12600}{100}\\Simple\ Interest = \$126[/tex]

Therefore, the answer is:

Interest earned is $126.

Jackie has a roll of ribbon that has 6 feet of ribbon. She is decorating for a birthday party and needs to wrap 10 gifts. Each gift requires 7.5 inches of ribbon. She estimated by multiplying 10 times 7 that she would have enough ribbon for the 10 gifts. Is she correct? Why or why not?

Answers

Answer:

She does not have enough ribbon.

Step-by-step explanation:

Each gift is equal to 7.5. Take 10*7.5=75in

In 6 feet how many inches are there? There is 12 in 1 feet. 6*12=72 inches. She would need to round up because of the .5

Answer:

No, she is not correct

Step-by-step explanation:

She used 7 instead of 7.5 inches, and her answer would be 5.83 feet, and would be under her total 6 feet. But, if she used 7.5 like she was supposed to, she would have gotten 6.25 feet, which would mean she wouldn't have enough.

Anyone know 1 and 2 with work shown please! ^^

Answers

Answer:

1. m∠R = 10

2. m∠P = 160

Step-by-step explanation:

The lines at the opposite are congruent so the angles have to be the same.

6x - 12 = 3x -1

subtract 3x from both sides

3x - 12 = -1

add 12 to both sides

3x = 11

divide by 3

x = 11/3

Now replace x in both the equations with 11/3:

3x - 1 = 3(11/3) - 1 = 11 - 1 = 10

6x - 12 = 6(11/3) - 12 = 66/3 - 12 = 22 - 12 = 10

So m∠R is 10

Now to find m∠P,

A triangle is 180 degrees so with angle P represented with x:

10 + 10 + x = 180

20 + x = 180

x = 160

m∠P = 160
