Explanation below:

Step-by-step explanation:

To solve this problem you have to look at the three measurements (base x length x height), which are 7in, 3in, and 5in. For the top of the rectangular prism, the surface area is 21in (7in x 3in) and since the bottom is the same, the bottom is also 21in. Now that you have the top and bottom, let's look at the sides. The surface area for the long-sides is 35in (7in x 5in) and since both sides are the same, they are both 35. The surface area for the ends of the rectangular prism is 15in (5in x 3in) and since they are both the same, they are both 15in. Now that you have figured out what measurement goes with what, add all them up. (21in +21in) = 42in | (35in +35in) = 70in | (15in + 15in) = 30in

42in + (70in + 30in)

42in + 100in

The surface area for the entire shape is 142 inches.

Write two mixed numbers so that all rules are applied:
1. One number is larger than the other by 4 2/3
2. The difference of the numbers is equal to the smaller number.
3. The sum of the numbers is natural number

Answers

Answer:

Step-by-step explanation:

“One number is larger than the other by 4 2/3”

x = y + 4⅔

“The difference of the numbers is equal to the smaller number.”

x-y = y

x = 2y

y + 4⅔ = 2y

y = 4⅔

x = 2y = 9⅓

“The sum of the numbers is natural number”

x+y ∈ ℕ

9⅓ + 4⅔ = 14 ∈ ℕ

Two rectangles are similar. The first rectangle has a length of 15 cm and a width of 10 cm. The width of the second rectangle is 25 cm. What is its length?

Answers

Answer:

Its length is 37.5 cm.

Step-by-step explanation:

If two rectangles are similar, their sides are proportional, that is, they have equal ratios. So

The first rectangle has a length of 15 cm and a width of 10 cm. The width of the second rectangle is 25 cm.

[tex]\frac{15}{10} = \frac{l}{25}[/tex]

[tex]10l = 25*15[/tex]

Simplifying by 10.

[tex]l = 2.5*15 = 37.5[/tex]

Its length is 37.5 cm.

Rapunzel sees a flying saucer. The radius of the flying saucer is 18 feet. What is the area of the flying saucer using 3.14 rounded to the nearest tenth

Answers

Answer:

[tex]1017.4ft^{2}[/tex]

Step-by-step explanation:

Area of a circle = [tex]\pi r^{2}[/tex]

However, the question wants to use 3.14 instead of [tex]\pi[/tex].

Since the radius is given, which is 18 feet, we can plug and chug.

[tex]A = 3.14*(18ft)^{2} \\A = 3.14*324ft^{2}\\A = 1017.36ft^{2}[/tex]

However, the question wants us to round it to the nearest tenth.

Therefore, the answer is [tex]1017.4ft^{2}[/tex]

A self-serve car wash charges $5.81 to use its facilities, plus an additional $0.51 for each minute the customer is at the self-serve car wash. If Tiffany was at the car wash for 5 minutes, how much was she charged?

Answers

$31.06
$5.81 + the 51 cents equals to $6.32. $6.32 times 5 equals $31.06. Hope this helps!:)

Answer:

Tiffany was charged $8.36

Step-by-step explanation:

From the question, we can create the following equation where "c" is the amount of money she was charged, and "m" is the number of minutes Tiffany is in the car wash...

c = 0.51m + 5.81

Since in our case "m" equals 5, then...

c = 0.51m + 5.81

c = 0.51(5) + 5.81

c = 2.55 + 5.81

c = 8.36

Therefore Tiffany was charged $8.36

Function p gives the perimeter of an equilateral triangle of side length s. It is represented by the equation p(s)=3x

a. What does P(s)=60 mean in this situation?

b. Find a value of s to make the equation P(s) = 60 true.

Answers

Answer:

A) p(s) means that the perimeter of the triangle is 60 units.

B) A value to make the equation true is s = 20

Step-by-step explanation:

In the equation p(s) = 60, 60 represents the perimeter of the equilateral triangle.

To find a value of s that makes the equation p(s) = 60 true, plug in 60 as p(s) and solve for s.

p(s) = 3s

60 = 3s

20 = s

So, s = 20 will make the equation true
