Answer: 30 seconds
Step-by-step explanation:
From the question, we are informed that one string flashes every 10 seconds while the other one string flashes every 15 seconds.
The number of minutes that it'll take before they both flash again at the same time will be gotten by calculating the LCM of 10 and 15. This will be:
10 = 10, 20, 30, 40, 50 ...
15 = 15, 30, 45, 60, 75 ....
We can see that the lowest common multiple of 10 and 15 is 30. Therefore, the answer is 30.
They'll both flash again at same time in 30 seconds.
A food pantry is making packages. Each package weighs 64 pounds.
Here are two situations. For each situation, write and solve an equation to represent the situation, then explain what your solution means in the situation. If you get stuck, try drawing a diagram. (upload your work when complete)
1.Each package contains 4 boxes. Each box contains a 7-pound bag of beans and a bag of rice.
2.The bags of rice are all identical. Each package contains 4 identical bags of rice and a 7-pound bag of beans.
Please i rly need this!!!!!!!!!
Answer:
1) x = 14.25 2) 9
Step-by-step explanation:
1) 1 Package = 4 boxes
1 Box = 7 pounds of beans
Your equation should be 4x + 7 = 64...
because 64 is the total pounds that each package weigh! 4 becomes a a variable; 4x because it has the word "each" in it. Mostly likely, when you see "each" that number becomes a variable. 7 is a just an number you have to add to the equation.
Solve!
4x + 7 = 64
- 7 - 7 Subtract 7 from both sides
4x = 57
4x / 4 = 57 / 4 Divide 4 from both sides
x = 14.25
2) 9

You have deposited SEK 10,000 in an account that gives 2% interest every year. How much have you received in interest after two years?
Answer:
404
Step-by-step explanation:
2% of 10000 = 200 in the first year, setting your account to 10200
2% of 10200 = 204 in the second year, setting your account to 10404
In the total of 2 years, you received 404 extra
Answer:
Deposite amount (P) = 10000
Interest ( R) = 2%
Years (T) = 2
Formula
S.I =PRT÷100
S.I =10000×2×2÷100
S.I =40000÷100
S.I =400
You have received interest after 2 years =400

Answer:
D
Step-by-step explanation:
Two lines are parallel if they have the same slope.
the given equation is in the form
y=mx+b
where
m=-5/2
b=-7
m is the slope. You can see this by noting that if you increase x by 1 you increase y by m.
So, in this case, you are looking for a line with slope of -5/2.
You can solve each of the choice equations for y to see which one has the right slope.
A: y=(2/5)x-6 no good
B: y=-(2/5)x-1 no good
C: y=(5/2)x-4 no good
D: y=-(5/2)x-4 GOOD

[tex]\sqrt[3]{8+3\sqrt{21} } + \sqrt[3]{8-3\sqrt{21} }[/tex] = 1Step-by-step explanation:
Given[tex]\sqrt[3]{8+3\sqrt{21} } + \sqrt[3]{8-3\sqrt{21} }[/tex]To find The value of the expressionSolutionLet's rewrite the given as:
[tex]\sqrt[3]{3\sqrt{21} + 8} - \sqrt[3]{3\sqrt{21} - 8}[/tex]Let the value is m and the expressions under 3rd roots are a and b, then we have
a = 3√21 + 8, b = 3√21 - 8m = ∛a - ∛bCube the both sides:
m³ = (∛a - ∛b)³m³ = a - b - 3[tex]\sqrt[3]{a^2b}[/tex] + 3[tex]\sqrt[3]{ab^2}[/tex]Simplify in bits:
a - b = 3√21 + 8 - 3√21 + 8 = 16ab = (3√21 + 8)(3√21 - 8) = 9*21 - 64 = 125∛ab = ∛125 = 5So the expression becomes:
m³ = 16 - 3[tex]\sqrt[3]{125a} + \sqrt[3]{125b}[/tex]m³ = 16 - 15∛a + 15∛bm³ = 16 - 15(∛a - ∛b)m³ = 16 - 15mSolve for m:
m³ + 15m - 16 = 0m³ - 1 + 15m - 15 = 0(m - 1)(m² + m + 1) + 15(m - 1) = 0(m - 1)(m² + m + 16) = 0m - 1 = 0, m² + m + 16 = 0m = 1 is the only real root, the quadratic equation has no real rootsThe answer is 1

Answer:
240 cm², A = 300 cm², and 540 cm²
Step-by-step explanation:
1) The area of a parallelogram is A = bh, so:
A = (20)(12)
A = 240 cm²
2) Similarly, the area of a rectangle is A = bh, so:
A = (15)(20)
A = 300 cm²
3) The composite area is the sum of both the rectangle's area and the parallelogram's area, so:
240 cm² + A = 300 cm² = 540 cm²
Answer:

carpeting is needed to cover a 60 feet length room and 40 feet width
Answer:
[tex]266[/tex] [tex]\frac{2}{3}[/tex] [tex]yards[/tex]
Step-by-step explanation:
1. Approach
First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is, [tex]3feet=1yard[/tex]. Next, find the area of the room by multiplying the length by the width.
2. Convert the unit of measurement
The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is, [tex]3feet=1yard[/tex].
[tex]60feet=20yards\\\\40feet=13\frac{1}{3}yards[/tex]
3. Find the area of the room
Now multiply the length by the width to find the area of the room.
[tex]20yards*13\frac{1}{3}yrads\\\\= 20 * \frac{40}{3}\\\\=\frac{800}{3}\\\\= 266\frac{2}{3}_{.}yards^{2}[/tex]

Meryl buys new baseball equipment for $2000. The purchase made is with a credit card that has a 19% APR. Meryl makes a $150 payment monthly. How many months will it take Meryl to pay off the balance?
Answer:
It will take Meryl 15.09 months to pay off the balance.
Step-by-step explanation:
This can be calculated using the formula for calculating the present value of an ordinary annuity as follows:
PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)
Where;
PV = Present value or the cost of the new baseball equipment = $2000
P = Monthly payment = $150
r = Monthly interest rate = annual percentage rate (APR) / 12 = 19% / 12 = 0.19 / 12 = 0.0158333333333333
n = number of months it will take Meryl to pay off the balance = ?
Substitute the values into equation (1) and solve for n, we have:
2000 = 150 * ((1 - (1 / (1 + 0.0158333333333333))^n) / 0.0158333333333333)
2000 / 150 = (1 - (1 / 1.0158333333333333)^n) / 0.0158333333333333
13.3333333333333 = (1 - 0.984413453650536^n) / 0.0158333333333333
13.3333333333333 * 0.0158333333333333 = 1 - 0.984413453650536^n
0.21111111111111 = 1 - 0.984413453650536^n
0.984413453650536^n = 1 - 0.21111111111111
0.984413453650536^n = 0.78888888888889
loglinearize both sides, we have:
nlog0.984413453650536 = log0.78888888888889
n = log0.78888888888889 / log0.984413453650536
n = -0.102984160720249 / -0.00682245957075587
n = 15.0948729929724
Rounding to 2 decimal places, we have:
n = 15.09
Therefore, it will take Meryl 15.09 months to pay off the balance.

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Parallel lines and Transvell.
We here are going to use the concept of Corresponding angles, co- interior angles and linear pair also Adjacent angles.
hence, we get as,
1.) x = 60° , y = 60°.....(vertically opposite angles)
2.) x = 120° , y = 120°
3.) x = 105° , y = 75°
4.) x = 140° and y = 40°
All are above done.

Part (a)
Answer: x^3 + 12x^2 + 47x + 60--------------------------
Work Shown:
Let's say we have
L = length = x+5W = width = x+4H = height = x+3To find the volume of the block, we multiply the length width and height.
So,
volume = (length)*(width)*(height)
V = L*W*H
V = LW*(x+3) .... replace H with (x+3)
V = LW*x + LW*3 .... distribute
V = Lx*(W) + 3L*(W)
V = Lx(x+4) + 3L(x+4) .... replace W with x+4
V = Lx^2 + 4Lx + 3Lx + 12L .... distribute
V = Lx^2 + 7Lx + 12L
V = x^2*(L) + 7x*(L) + 12*(L)
V = x^2*(x+5) + 7x*(x+5) + 12*(x+5) .... replace L with x+5
V = x^3 + 5x^2 + 7x^2 + 35x + 12x + 60 .... distribute
V = x^3 + 12x^2 + 47x + 60
x^3 + 12x^2 + 47x + 60 is the polynomial in standard form that represents the volume of the block.
=======================================================
Part (b)
Answer: 336 cubic feet--------------------------
Work Shown:
We can plug x = 3 into the polynomial we found
V = x^3 + 12x^2 + 47x + 60
V = (3)^3 + 12(3)^2 + 47(3) + 60
V = 27 + 12(9) + 47(3) + 60
V = 27 + 108 + 141 + 60
V = 336
Or we could find the volume like this
V = L*W*H
V = (x+5)*(x+4)*(x+3)
V = (3+5)*(3+4)*(3+3)
V = (8)*(7)*(6)
V = 336
Either way, we get the same volume of 336 cubic feet.
