Odpowiedź:
450 płytek
Wyjaśnienie krok po kroku:
Jeśli się uwzględni:
Kształt łazienki = kwadrat
Powierzchnia kwadratu = s²; gdzie, s = długość boku
Długość boku, s = 3m
Powierzchnia łazienki = 3² = 9m²
Wymiar płytek z terakoty = 10cm * 20cm
Powierzchnia płytek = 10 * 20 = 200 cm²
1 m² = 100 * 100 = 10000 cm²
W związku z tym,
Powierzchnia łazienki:
9m² = (10000 * 9) = 90000 cm²
Liczba płytek:
Powierzchnia łazienki / Powierzchnia jednej płytki
90 000 cm² / 200 cm²
= 450 płytek
Lucy, Luke, and Lilly went trick-or-treating on Halloween. After they finished, they compared the amount of candy they all had. Luke had twice the amount Lilly had, and Lucy had 15 less than 3 times the amount Lilly had. If together, they had 225 candies, how many candies did Lucy have? PLEASE HELP URGENT
Hi there!
Let think talk about these clues we have right now...
Luke is x2 more than Lily.
Luce is 45 less candy than Lily since 3 times 15.
225 candys in total...
Let make a random guess...
Lily: 70
Luke: 140
Lucy: 35
Total: 245
Now we know that there must be a half candy since it’s a odd number at the end of that...
Lily: 67.5
Luke: 135
Lucy: 22.5
Total: 225
But we are asked for only Lucy...
So the answer to this problem is 22.5.

Basil was shown this enlargement, and he was asked to find the perimeter of the enlarged shape. His work is shown below.
The question is incomplete. The complete question is :
Basil was shown this enlargement, and he was asked to find the perimeter of the enlarged shape. His work is shown below.
Where, if any, did Basil first make a mistake in his work?
Solution :
Not -- Basil did not make any mistakes in his work. He found out the perimeter of an enlarged shape.
Perimeter is the total measure of the outer lining or the total outer length of the body or the shape. For different shapes, the perimeters will be different. Basil measure the outer length of the body and found out the perimeter.

Is value of X in the equation 6x+3+4x= 1/2(9+10x)
Answer:
x = 0.3
Step-by-step explanation:
6x + 3 + 4x = 1/2 (9 + 10x)
=> 10x + 3 = 1/2 *9 + 5x
=> 5x + 3 = 9 / 2
=> 5x = 9 / 2 -3
=> 5x = (9 - 6) / 2
=> 5x = 3 / 2
=> x = 3 / 10
=> x = 0.3

Madeline is going to invest in an account paying an interest rate of 4.4% compounded
annually. How much would Madeline need to invest, to the nearest ten dollars, for
the value of the account to reach $16,600 in 12 years?
Answer:
$9540
Step-by-step explanation:
A = P(1 + r)^t
16600 = P(1.044)^12
P = 16600/(1.044)^12
P = $9,543.64

A new car is purchased for 24600 dollars. The value of the car depreciates at 5.5% per year. To the nearest year, how long will it be until the value of the car is 11300 dollars?
Answer:
The number of years until the value of the car is 11300 dollars is 9 years.
Step-by-step explanation:
This can be calculated using the following formula:
Value of the Car = Purchase cost - (Annual depreciation expenses * N) ........ (1)
Where;
N = Number of years until the value of the car is 11300 dollars
Purchase cost = $24,600
Annual depreciation rate = 5.5%
Annual depreciation expenses = $24,600 * 5.5% = $1,353
Value of the car = $11,300
Substituting the value into equation (1) and solve for N, we have:
$11,300 = $24,000 - ($1,353 * N)
$1,353 * N = $24,000 - $11,300
$1,353 * N = $12,700
N = $12,700 / $1,353
N = 9.38654841093865
Rounding to the nearest year as required by the question, we have:
N = 9
Therefore, the number of years until the value of the car is 11300 dollars is 9 years.

A line is parallel to y = 3x + 5 and
intersects the point (-2, 6). What is
the equation of this parallel line?
Start by entering this into point-slope form.
y- [?] = [](x
](x-[]).
Answer:
Im not like 100% sure but i think you answer is
y-6=3[x-(-2)]
y=6+3x+6
y=3x+12
And i believe that this is parallel to y
Answer:
y = 3x + 12Step-by-step explanation:
Parallel lines have same slope
Given line
y = 3x + 5The line that passes through (-2, 6) and with the slope of 3 is:
y - y₁ = m(x - x₁)y - 6 = 3(x - (-2))y - 6 = 3(x + 2)Convert the equation into slope-intercept form:
y - 6 = 3x + 6y = 3x + 6 + 6y = 3x + 12Bettina bought 8 pairs of socks for $23.20. Nancy bought 10 pairs of socks for $30.00. Nancy says that she paid less per pairs of socks than Bettina. Is Nancy correct
Answer: yes, Nanay did´t buy more pairs of socks, she had bayed more. I hop that this is helpful.
