Yes 1 5/7 and 4 2/7 is a solution. Adding those two numbers equals 6 because 5/7 + 2/7 = 1, then you have 4 + 1 +1 = 6
Two other solutions to x + y = 6 are any combinations of numbers when added together equal 6.
x = 5, y = 1
and
x = 2, y = 4

It takes 41.7 BTUs to heat a 5 gallon jug of water. What is the density of a gallon of water. Round your answer to the nearest hundredth
Answer: The density is 0.002 lb/cm^3
Step-by-step explanation:
1 BTU is neded to increment the temperature of 1 Lb of water by 1° F
Then if we need 41.7 BTU to increment 1°F of 5 gallons of water, this means that in the 5 gallons we have a mass of 41.7 lbs of water.
And as you know, density = mass/volume
now, 1 gallon = 3.78 liters = 3780 cm^3
then 5 gallons = 5*3780 cm^3 = 18900 cm^3
The density is D = 41.7Lb/18900 cm^3 = 0.002 lb/cm^3

O D. (x+ 10)(x+4)
Answer:

Step-by-step explanation:
(x-4) x (x-10)
Answer:
B
Step-by-step explanation:
Given
x² - 14x + 40
Consider the factors of the constant term (+ 40) which sum to give the coefficient of the x- term (- 14)
The factors are - 10 and - 4, since
- 10 × - 4 = + 40 and - 10 - 4 = - 14, thus
x² - 14x + 40 = (x - 10)(x - 4) → B

Answer:
x=50 ∠BCX=65
Step-by-step explanation:
The angles is a triangle add up to 180 so
70+45+∠BCX=180 so
115+∠BCX=180 (subtract 115 from both sides)
∠BCX=65
A line adds up to 180
so 2x+15+65=180
so 2x+80=180 (subtract 80 from both sides)
2x=100 (divide by 2)
x=50

Uta invests an amount into a compound interest investment account that pays 6% a year. After six years, she withdraws her total balance of $500. Using the formula A = P (1 + r) Superscript t, how much money did Uta initially invest?
$180.00
$320.00
$352.48
$471.70
Answer: $352.48
Step-by-step explanation:
Hi, to answer this question we have to apply the formula:
A = P (1 + r)^t
Where
A: total balance after invest
P: principal amount invested
r = interest rate (in decimal form)
t = time (years)
Replacing with the values given:
500= P (1+0.06)^6
Solving for P:
500 = P (1.06)^6
500 / ( (1.06)^6)=P
500 / 1.4185 =P
$352.48= P

15 kilograms of rice are separated equally into 4 containers. How many kilograms of rice are in each
container? Express your answer as a decimal and as a fraction,
Final answer:
Each container will have approximately 3.75 kilograms of rice, which can be expressed as 3.75 kg or 15/4 kg.
Explanation:
To find out how many kilograms of rice are in each container, we need to divide the total weight of the rice by the number of containers. In this case, we have 15 kilograms of rice and 4 containers, so we divide 15 by 4. The result is 3.75 kilograms.
So, each container will have 3.75 kilograms of rice.
As a decimal, this can be expressed as 3.75 kg. As a fraction, it can be written as 15/4 kg.

6! =
Answer:
6! = 720
Step-by-step explanation:
In evaluating factorial functions, generally
n! = n(n-1)(n-2)(n-3)...× 1
We can see that as we are moving, the value keep decreasing by 1 until it reaches the least value which is 1.
6! = 6(6-1)(6-2)(6-3(6-4)(6-5)
6! = 6×5×4×3×2×1
6! = 720
60% of x is equal to 87. Write an equation that expresses the relationship between 60%, x, and 87.
Answer: 0.6x = 87
Step-by-step explanation:
Hi, to answer this question we have to write en equation:
We have to multiply the variable x by the percentage given (60%) in decimal form (divided by 100). That expression must be equal to 87.
Mathematically speaking:
x (60/100) = 87
0.6x = 87
Feel free to ask for more if needed or if you did not understand something.
This equation states that 60% (or 0.60) of x is equal to 87.
To express the relationship between 60% of x and 87, we can set up an equation. Since 60% can be written as 0.60, we can write:
0.60x = 87
To solve for x, we divide both sides of the equation by 0.60:
x = 87 ÷ 0.60
So, x will be:
x = 145
This shows that 60% of 145 is equal to 87.
The length of the hypotenuse of a right triangle is 15 in. and one leg has length of 6 in. Find the length of the other leg.
Answer:
C. square root 189 in.
Step-by-step explanation:
2A - 5B + 4X = C - 8X
Answer:
(5B+C-2A)/8 = x
Step-by-step explanation:
2A - 5B + 4X = C - 8X
subtract 4x from both sides
2A - 5B + 4X-4x = C - 8X-4x
2A - 5B = C - 12X
subtract C from both sides
2A - 5B -C = C-C - 8X
2A - 5B -C = - 8X
divide both sides by -8
(2A - 5B -C)/-8 = - 8X/-8
(-2A+5B+C)/8 = x
(5B+C-2A)/8 = x

Which expression represents the total surface area, in square centimeters, of the square pyramid?
(8.2) (8.2) + 4 (one-half (8.2) (10.3))
(8.2) (8.2) + 4 (one-half (8.2) (11.1))
(8.2) (10.3) + 2 (one-half (10.3) (10.3)) + 2 (one-half (8.2) (10.3))
(8.2) (10.3) + 2 (one-half (10.3) (11.1)) + 2 (one-half (8.2) (11.1))
Answer:
(8.2) (8.2) + 4 (one-half (8.2) (11.1))
Step-by-step explanation:
Formula for calculating the surface area of a square based pyramid is expressed as:
Surface area = A + 1/2ps
A is the base area
P is the perimeter of base
S is the slant side.
Since the base of the pyramid is a square, then
Base Area A = L²
A = 8.2²
A = 67.24cm²
Perimeter of square = 4L = 4(8.2)
= 32.8cm
Slant Height = 11.1cm
On substituting the gotten value:
Surface area = 8.2(8.2) + 1/2 [4(8.2 (11.1)]
Based on the solution above, the expression below is correct.
S =(8.2) (8.2) + 4 (one-half (8.2) (11.1))
A right triangle is inscribed in a circle as shown. What is the area of the shaded region. Diameter of 12 and 9 cm in triangle
Answer:
[tex]36\pi -18\sqrt{7}[/tex]
Step-by-step explanation:
Every inscribed right triangle has its hypotenuse as the same size of the Diameter. Assuming that, this is the case check the picture below.
So the hypotenuse= D=2R=12
Shaded Area = Area of the Circle- Area of the TriangleArea of Circle:[tex]A_{circle}=\pi (6)^{2}=36\pi[/tex]
Area of the Triangle:Finding the Triangle base via the Pythagorean Theorem
[tex]a^2=b^2+c^2\\12^2=9^2+c^2\\144-81=c^2\\c=\sqrt{63}\\c=3\sqrt{7}\approx 7.94[/tex]
Now plugging in the base of the triangle on that formula:
[tex]A=\frac{bh}{2}\\A=\frac{3\sqrt{7}*12}{2}\\A=18\sqrt{7}[/tex]
Finally,
Shaded Area = [tex]36\pi -18\sqrt{7} cm^{2} \approx 65.48 cm^{2}[/tex]

Volume of a rectangular prism is 275 cubic Inches. The base is a square with the
side length of 5 inches. Find the height of this prism. Write the formula, and solve
as an equation. V=s?h
Answer:
11 in
Step-by-step explanation:
Starting with the base, we know the side length is 5 inches. So with that in mind, we can do 5 x 5 to get the area of the base, 25. We also know the volume of the whole rectangular prism is 275, so we can do 275 ÷ 25. The quotient of that is 11.
We can check our answer by doing 11 x 25. This gives us 275, proving that it is correct.
Hope this helped! :)
What is 3=7(4 - 2u)-6u
Answer:
u = 5/4
Step-by-step explanation:
to evaluate for the value of u we would simply open the bracket and then evaluate for the value of u by collecting the like terms together.
solution
3=7(4 - 2u)-6u
3 = 28- 14u - 6u
collect the like terms
3 + 14u + 6u = 28
20u = 28 - 3
20u = 25
divide both sides by the coefficient of u which is 20
20u/20 = 25/20
u = 5/4
Answer:
[tex]u = 5/4[/tex]
Step-by-step explanation:
Step 1: Distribute on the right side
[tex]3 = 7(4 - 2u) - 6u[/tex]
[tex]3 = (7 * 4) + (7 * -2u) - 6u[/tex]
[tex]3 = 28 - 14u - 6u[/tex]
Step 2: Combine like terms
[tex]3 = 28 + (-14u - 6u)[/tex]
[tex]3 = 28 + -20u[/tex]
Step 3: Subtract 28 from both sides
[tex]3 - 28 = 28 - 20u - 28[/tex]
[tex]-25 = -20u[/tex]
Step 4: Divide both sides by -20
[tex]-25 / -20 = -20u / -20[/tex]
[tex]5/4 = u[/tex]
Answer: [tex]u = 5/4[/tex]

Step-by-step explanation:
Simplifying
8 = 3x + -1
Reorder the terms:
8 = -1 + 3x
Solving
8 = -1 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
8 + -3x = -1 + 3x + -3x
Combine like terms: 3x + -3x = 0
8 + -3x = -1 + 0
8 + -3x = -1
Add '-8' to each side of the equation.
8 + -8 + -3x = -1 + -8
Combine like terms: 8 + -8 = 0
0 + -3x = -1 + -8
-3x = -1 + -8
Combine like terms: -1 + -8 = -9
-3x = -9
Divide each side by '-3'.
x = 3
Simplifying
x = 3 this took forever to type hope it helped
