Answers

Answer 1

Answer:

PETER 18

POL 21

MARY 26

Step-by-step explanation:

I dont know if I did in the right way...

1st: Take any number for peter's or pol's age

I took 18 for peter, RANDOMLY

2nd: Subtract the age from the total to get pol's age

39-18=21 Hence, pols age is 21

3rd: Subtract peter's age from the total to get marys age

47-18=26 Hence, Marys age is 26

4th: Add the age of pol and mary

aaand, you get 47

Done!

Hope it helps!!!

Answer 2

Answer:

Peter is 18, Pol is 21 and Mary is 26 years old.

Step-by-step explanation:

Pe + Po = 39 .......A

Pe + M = 44   .......B

Po + M = 47   ........C

Equation B - Equation C gives:

Pe - Po + M - M = 44 - 47

Pe - Po = -3

Add this equation to A:

2Pe + Po - Po = 39 - 3

2Pe = 36

Pe = 18.

Substituting for Pe in B

18 + M = 44

M = 44 - 18 = 26.

Substituting for M in C:

Po + 26 = 47

Po = 47 - 26 = 21.

Kai pen for Ruth’s dog is 7 feet long and 6/1.3 feet wide. Her friend Ralph’s dog pen is 14 feet long and 6/1.2 feet wide. How many times larger is the area of Ralph’s dog pen?

Answers

Answer:

The area of Ralph's dog pen is 2.05 times larger than the area of Ruth's dog pen.

Step-by-step explanation:

Given that the dog pen for Ruth's dog is 7 feet long and 6 / 1.3 feet wide, while her friend Ralph's dog pen is 14 feet long and 6 / 1.2 feet wide, to determine how many times larger is the area of Ralph's dog pen, the following calculation must be performed:

1/3 = 0.333

1/2 = 0.5

7 x 6.333 = X

44,333 = X

14 x 6.5 = X

91 = X

44,333 = 100

91 = X

91 x 100 / 44.333 = X

9,100 / 44,333 = X

205.26 = X

100 = 1

205.26 = X

205.26 / 100 = X

2.05 = X

Thus, the area of Ralph's dog pen is 2.05 times larger than the area of Ruth's dog pen.

Answer:

156 inches^2

Step-by-step explanation:

The area of a triangle is 1/2 base x height

All of the triangles have a base of 6 inches and a height of 10 inches.

so 1/2 6 x 10= 30

There are 4 triangles with an area of 30 square inches

and then the square in the middle has a length of 6 in and a width of 6 in so it has an area of 36 in^2

so in total you would have 30+30+30+30+36, or 156

Find the least whole number N greater than 40 for which:
( I ) N divided by 4 leaves a remainder of I. and
(2) N divided by 5 leaves a remainder of 3.

PLS HELP

Answers

Answer:

*Below*

Step-by-step explanation:

Let the number be N.

N divided by 4 leaves 1 as the remainder. This means N - 1 is divisible by 4.

So, we can write N - 1 = 4k1, where k1 is an integer 10 or greater

N divided by 5 leaves 3 as the remainder. This means N - 3 is divisible by 5.

So, we can write N - 3 = 5k2, where k2 is an integer 8 or greater

From above, we get 4k1 - 2 = 5k2

4k1 - 5k2 = 2

k1 = 13, k2 = 10 and the number is XXXXX = 4k1 + 1 = 4(13) + 1 = 53

Valentina made costume crowns for the king and the prince in her school play. She used 5 red gems and 8 purple gems for the king's crown. The prince's crown was smaller, so Valentina only used 4 red gems and 5 purple gems for that one. Which crown had a greater ratio of red gems to purple gems?

Answers

Answer:

The prince's crown had a greater ratio of red gems to purple gems.

Step-by-step explanation:

KING = 5 red / 8 purple

PRINCE = 4 red / 5 purple

Times the ratio for the king by 5

5(5) / 8(5) = 25/40

Times the ratio for the prince by 8

4(8) / 5(8) = 32/40

The prince has a greater ratio of red gems

Hope this is right, and sorry if it is incorrect. Have a good day!

decagon's are shapes with 10 sides I believe, where you are looking of row with 8. So, this is not it. Eliminate A.

Answer:

Exponential, quadratic, Linear

Step-by-step explanation:

So ok, let me give you a reminder on what these functions are.

So, a linear function is quite literally a strait line. Basically, the values of x and y are being added and subtracted by a ever-constant value.

Next is a quadratic function, which basically a u or upside-down u. The numbers increase, and then decrease, or vise versa. You can think of it like a bird flying up to the clouds, and then gliding back down.

Finally we have exponential functions. Which is a function that gets very, very high. This is because the number is squared over and over again. The bigger the x or y value gets, the bigger it will be next time its squared.

Just for a visual, I took some photos of the different types of functions.

Now, lets get into the problem.

For the first problem:

X is increasing by 1.

Y is increasing by....Lets see.

So it seems y is getting diving by 2 each time the x increases by 1.

It seems sort of like a linear function, right?

Well yes, but if you recall what I said above, the values are being added to or subtracted to. This is division, and is never a exact number. So it cant be that. The values dont go up and then back down, or vise versa like in a quadratic function. Well, could the value of y in this graph be squared by 1/2 to get our answer? Yes! So the answer must be exponential!

Now, lets try to speed through to the next ones.

We can see that the x is changing by 1, while the y changes by a odd and not always the same amount. This istantly means that it cannot be linear. It could be exponential, but if you look closly, you can see that at the end, the values start to decrease. Remember what I said about quadratic function? Then this must be a quadratic function!

That sums up our second function, lets look at our third.

The x is increasing by 1, and the y values are increasing by 6.

Hmm, it seems like each time x increases by 1, y increases by 6. This means it must be a linear function! After all, linear functions increase by a constant amount.

I hope this helps you with your problem and any you have in the future!

Answer:

Question: The Design For The Palladium Window Shown Includes A Semicircular Shape At The Top. The Bottom Is Formed By Squares Of Equal Size. A Shade ...

Step-by-step explanation:

Answer/Step-by-step explanation:

Part 1 out of 2

What is the area of the window? Use 3.14 for π.

Separate the palladium window into simpler shapes: a large square and a large semicircle. The large square is made up of 16 smaller squares and the large semicircle is made up of 5 smaller shapes. Each small square in the window has an area of 169 in2.

Find the area of the large square in the window.

169 · 16 = 2,704

The area of the large square in the window is 2,704 in2.

Find the side length of the large square in the window.

A = s2

2,704 = s

52 · 52 = s

52 = s

The side length of the large square in the window is 52 in.

Find the area of the semicircle in the window. The side length of the large square is equal to the diameter of the semicircle. Round your answer to the nearest whole number.

A =   1 /2 πr2

A =   1/ 2

(3.14) (26)2

A = 1,061

The area of the semicircle in the window is 1,061 in2.

Add the areas to find the total area of the window.

A = 1,061 + 2,704

A = 3,765

The area of the window is 3,765 in2.

Part 2 out of 2

What is the area of the shade? Round your answer to the nearest whole number.

Separate the shade into simpler figures: a large rectangle and a large semicircle.

Find the length of the rectangle in the shade by adding 4 inches to both sides of the length of the large square in the window.

s = 52 + 8

s = 60

The length of the rectangle is 60 in.

Find the width of the rectangle in the shade by adding 4 inches to the side length of the large square in the window.

s = 52 + 4

s = 56

The width of the rectangle is 56 in.

Find the area of the rectangle in the shade.

A = LW

A = 60 · 56

A = 3,360

The area of the rectangle in the shade is 3,360 in2.

Find the area of the semicircle in the shade. The length of the large square in the shade is equal to the diameter of the semicircle in the shade. Round your answer to the nearest whole number.

A =   1/ 2 πr2

A =   1/ 2

(3.14) (30)2

A = 1,413

The area of the semicircle in the shade is 1,413 in2.

Add the areas to find the total area of the shade.

A = 3,360 + 1,413

A = 4,773

The area of the shade is 4,773 in².

1 /2

(3.14) (30)2A = 1,413 The area of the semicircle in the shade is 1,413 in2. Add the areas to find the total area of the shade. A=3,360 + 1,413A=4,773The area of the shade is 4,773 in².
