if you subtract 13 from my number and multiply the difference by -4, the result is -40, what is the number?
Answer:
23
Step-by-step explanation:
let the number = X
subtracting 13 from X = X -13
multiplying the difference by -4= (X -13)×-4
the result is -40 means (X-13)×-4=-40
(X- 13)×-4 = -40
-4 X +52 = -40
collect like term
-4 X = -40-52
- 4X = -92
dividing bothsides by -4
-4 X /-4 = -92/-4
X = 23
What is the volume of a sphere with a radius of 39.6 m, rounded to the nearest tenth of a cubic meter?
The volume of a sphere with a radius of 39.6 m, rounded to the nearest tenth is 341416.9 cubic meters
The volume of a sphere can be calculated using the formula V = (4/3)πr³, where V is the volume, π is a constant with a value of approximately 3.14, and r is the radius of the sphere.
To find the volume of a sphere with a radius of 39.6 m, we can substitute this value into the formula and simplify:
V = (4/3)πr³
V = (4/3)π(39.6)³
V ≈ 341416.8 cubic meters
Since the question asks us to round to the nearest tenth of a cubic meter, we look at the digit in the hundredth place, which is 6 in this case. Since 6 is greater than or equal to 5, we round up the digit in the tenths place, which is 8. Therefore, the volume of the sphere rounded to the nearest tenth of a cubic meter is:
V ≈ 341416.8 cubic meters ≈ 341416.9 cubic meters
In summary, to find the volume of a sphere, we use the formula V = (4/3)πr³, where V is the volume, π is a constant, and r is the radius. We can then round the answer to the nearest tenth of a cubic meter by looking at the digit in the hundredth place and rounding up if the digit in the tenths place is 5 or greater.

Hello, please help! I will be using this a lot within the next few days lol
Answer:
1/2
Step-by-step explanation:
1/3 + 1/6
LCM of 3 and 6 is 6.
therefore, multiple the fraction that doesn't have 6 as denominator with a fraction that makes the denominator equal to the LCM.
1/3 × 2/2 = 2/6
(we have used 2/2 because 3×2= 6)
so,
2/6+1/6 = 2+1/6
(2 + 1 whole divided by 6)
therefore we get,
3/6
on simplification,
3/6 = 1/2 = 0.5
hope it helps!!
PLEASE MARK BRAINLIEST..
Answer:
1/3 + 1/6 = 2/6 + 1/6 = 1/2 (simplified from 3/6)
Step-by-step explanation:
since 1/3 = 2/6 (to get the same denominator)
2/6 + 1/6 = 3/6 (or 1/2 simplified, when divided by 3/3)
so 2/6 + 1/6 = 3/6

Let's take a look at our problem, it says we need to find the perimeter of the rectangle; luckily, we have all the info we need!
This is the perimeter formula:
⇒[tex]\frak{Perimeter_{rectangle}=2(a+b)}[/tex]
So basically, it says we need to take the rectangle's length (a), add it's width (b), and multiply their sum times two, and this is equal to the perimeter.
The problem tells us that:
⇒ Length 5x+5
⇒ Width 2x-1
As the equation says, we should add the length and the width:
⇒ 5x+5+2x-1
⇒5x+2x+5-1
⇒7x+4
· Hooray! We found the perimeter!
× Actually, we didn't find the perimeter, yet! Remember, we also need to multiply by 2.
Multiplication results in
⇒ 2(7x+4)
expanding the expression
⇒14x+8
· Now we did find the perimeter, and what's more, we've written it in simplest form.

Step-by-step explanation:
Hello again, similar to the other questions, these problems use the same formulas.
1. volume of a rectangular prism is: V = lwh, where l = length, w = width, h = height. Substitute known values into this equation: V = 4.5 x 7 x 16.5 and we get V = 519.75 cubic cm.
2. V = (1/2)bhl, where the base and height are dimensions of the triangle. V = (1/2)6.2 x 2 x 3.1 and we get V = 19.22 cubic cm
3. V = Bh, where B is the base area and h is the perpendicular height. Substitute known values into equation: V = 52(11.8). So, V = 613.6 cubic cm.
4. And again, V = Bh. Substitute given values into this equation: V = 79.4(17.2), which means V = 1365.68 cm^3

Length of the base of the given triangle is (x+3) units and the perpendicular height is (x-1)units. If the area of the triangle is 10 square units, show that x satisfy the equation x2 + 2x - 23 = 0 Solve above equation and find the value of x to the nearest whole number and calculate the perpendicular height of the triangle. (Take V6 = 2.45)
Step-by-step explanation:
the area of a triangle is
baseline × height / 2
so, in our case we know this is 10 :
(x+3)(x-1)/2 = 10
(x+3)(x-1) = 20
x² - x + 3x - 3 = 20
x² + 2x - 23 = 0
that is exactly the provided equation. so, yes, x satisfies it.
the general solution to a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 2
c = -23
x = (-2 ± sqrt(2² - 4×1×-23))/(2×1) =
= (-2 ± sqrt(4 + 92))/2 = (-2 ± sqrt(96))/2 =
= (-2 ± sqrt(16×6))/2 = (-2 ± 4×sqrt(6))/2 =
= -1 ± 2×sqrt(6)
x1 = -1 + 2×sqrt(6) = 3.898979486... ≈ 4
or using sqrt(6) ≈ 2.45
= -1 + 2×2.45 = -1 + 4.9 = 3.9 ≈ 4
x2 = -1 - 2×sqrt(6) = -5.898979486... ≈ -6
or using sqrt(6) ≈ 2.45
= -1 - 2×2.45 = -1 - 4.9 = -5.9 ≈ -6
x2 would give us negative lengths for the triangle, which does not make sense.
so, x = 4 is our solution.
and that makes the height x-1 = 4-1 = 3 units.

What is the angular speed about?To solve for the angular speed, you can use the formula of"
Given that the diameter is 80 feet, so we know the radius will be 40 feet.
The Ferris wheel bottom is 20 feet high, so we add the radius we get that the middle of the Ferris wheel is 60 feet high.
Finally, the Ferris wheel completes 1 ½ rotation (2π radians) in 1 minutes. So we say that the Ferris wheel is said to spins at π rad/min.
Angular velocity ( 1 ½ rev/1min)( 1min/60 sec)
C = 2π(60)
C ≈ 377.04 feet
540 revolution (1 ½ rotations) is 60 seconds, the speed is then
s = d/t
s = 377.06 ft / 60 sec
