Answer:
1 ton = 1000 kg
So, 17 ton = 17 × 1000
= 17000 kg
17000 + 200 kg = 17200 kg
[tex] \frac{17200}{8} = 2150kg[/tex]

(2n3 - 3n4 + 7n) - (n3 - 8n4 - 7n)
Answer:
Step-by-step explanation:
(2n³ - 3n⁴ + 7n) - (n³ - 8n⁴ - 7n) = 2n³ - 3n⁴ + 7n - n³ + 8n⁴ + 7n
{Here -1 is distributed }
= 2n³ - n³ - 3n⁴ + 8n⁴ + 7n + 7n
{Combine like terms}
= n³ + 5n⁴ + 14n
Answer:
The answer is: n^3 + 5n^4 + 14n

a. x + 13 = 0
x = -13
x-7= 0
x= 7
b. 2x +3 = 0
2x = -3
x= -3/2 or -1.5
3x -7 = 0
3x = 7
x = 7/3

The smallest circle in the figure has a radius of 2 inches. Which equation gives the area A of the shaded part of the figure? Recall that A = (pi)r^2
Answer:
60π in²
Step-by-step explanation:
Inner Circle:
r = 2 in
Area of inner circle = πr²
= π* 2 * 2
= 4π in²
Middle circle:
r = 6 + 2 = 8 in
Area of middle circle = π * 8 * 8
= 64π in²
Area of shaded region = area of middle circle -area of inner circle
= 64π - 4π
= 60π in²
Answer:
A = 60pi
Step-by-step explanation:
the radius of the smallest circle is 2 inches so that would give us an area of 4pi. the distance in the shaded part is 6 inches, since we're wanting to find the area of the shaded part, we'll add the radius of the smallest circle, 2 inches, and add it to the length of the shaded circle, 6 inches, to get a radius of 8 inches. plug 8 inches into the formula and youll get 64pi then subtract the 4pi from 64pi and youll get 60pi, which is the area of the shaded part of a circle.
5^2x = 3(2^x) find x please show steps
Step-by-step explanation:
the answer is in the image above
Answer:
Step-by-step explanation:
There is a possible issue in your question...
As written it can be interpreted in two ways
like this #1 :
[tex]5^{2x} = 3(2^x)[/tex]
or like this #2 :
[tex]5^2x = 3(2^x)[/tex]
VERSION #1
divide by the 2^x
[tex]\frac{5^{2x} }{2^x} = 3[/tex]
to be able to get to the exponent you have to take "logs"
... look up the rules for logs ... log(ab) = log (a)+log(b) , log(a/b) = log(a)-log(b) etc.
if you take the logs of both sides the using the quotient rule and the exponent rule ....result the result is...
[tex]5^{2x}=3\left(2^x\right)\quad :\quad x=\frac{\ln \left(3\right)}{2\ln \left(5\right)-\ln \left(2\right)}\quad \left(\mathrm{Decimal}:\quad x=0.43496\dots \right)[/tex]
VERSION #2
[tex]5^2x\:=\:3\left(2^x\right)[/tex]
25 x = 3(2^x)
[tex]\frac{25}{3} = \frac{2^{x} }{x}[/tex]
This gets really nasty, and I assume that it is not the original problem..
[tex]x=-\frac{\text{W}_{-1}\left(-\frac{3\ln \left(2\right)}{25}\right)}{\ln \left(2\right)},\:x=-\frac{\text{W}_0\left(-\frac{3\ln \left(2\right)}{25}\right)}{\ln \left(2\right)}\quad \mathrm{ }:\quad x=5.52482 ,\:x=0.13144[/tex]

Step-by-step explanation:
What a unique handwriting you have there. Anyways for this types of questions you just have to imagine a right-angled triangle and write down the values and an angle (2A).
First, to find height of the triangle, you can try using Pythagorean theorem, √(5²-3²) and you'll get the value 4.
Remember the formula,
sin a = opposite/hypothenuse.
Substitute the values in,
sin 2A = 4/5
solve the following pair of simultaneous equations. you can use any 3 methods. 2x- y= 5, x+2y=5.

Yes; 1,100 is less than 1,500.
No; 1,100 is more than the 400 he burned off at the gym.
No; 1,100 will cause him to exceed 1,900.
Yes; 1,100 is less than 1,900.
Answer:
Option 3
Step-by-step explanation:
If he burned off 400 calories from 1500 consumed calories, he has 1100 consumed calories. 1900 - 1100 = 800 calories left to consume.
While option 2 also says no, it's not the right reason.
The calories left to consume for the day is 800 calories.
No, 1,100 will cause him to exceed 1,900.
Given,
Jace has consumed 1,500 calories so far today.
He has also burned off 400 calories at the gym.
He would like to keep his daily calorie total to 1,900 calories per day.
We need to find how many calories he has left to consume for the day.
And see which option is the best choice.
We have,
Calories consumed in a day = 1500
Burned calories = 400
Calories to keep in a day = 1900
Find the Calories left
= 1500 - 400
= 1100
Find how many calories need to be consumed to keep 1900 calories.
= Calories needed to keep in a day - calories remaining after burned
= 1900 - 1100
= 800
We see that the calories left to consume is 800 calories.
So 1100 is not a viable solution. It will cause him to exceed 1,900.
Thus,
The calories left to consume for the day is 800 calories.
No, 1,100 will cause him to exceed 1,900.
