Hi there!
I do not know the other values of the pay check, so I will explain to you how to solve for 40% of the 270 dollars. To solve, we'll need to set up a proportion. That proportion is 40/100 = x/270. Next, we need to cross-multiply: 100x = 10800. Lastly, we'll divide to figure out what 40% of 270 is. x = 108.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Area = (base)*(height)
15 = (x+7)(x-7)
(x+7)(x-7) = 15
x^2 - 49 = 15
x^2 - 49+49 = 15+49
x^2 = 64
sqrt(x^2) = sqrt(64)
x = 8 ... note that x can't be negative
If x = 8, then the base is...
x+7 = 8+7 = 15
Therefore the base is 15 units.
(the height is x-7 = 8-7 = 1 unit)
Answer: 1.574 × 10-3
Step-by-step explanation:
To convert 0.001574 into scientific notation, follow these steps:
Move the decimal 3 times to right in the number so that the resulting number, m = 1.574, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -3
Write in the scientific notation form, m × 10n
= 1.574 × 10-3
Solution:
Consider the Given Isosceles Triangle
Considering the Possibilities
Case 1. When two equal angles are of 70°
Let the third angle be x.
Keeping in mind , that sum of Interior angles of Triangle is 180°.
70° + 70° + x= 180°
140° +x= 180°
x= 180°- 140°
x= 40°
Case 2:
When an angle measures 70°, and two equal angles measure x°.
Keeping the same property of triangle in mind, that is sum of interior angles of triangle is 180°.
70° + x° + x° = 180°
⇒ 70° + 2 x° = 180°
⇒ 2 x° = 180° - 70°
⇒ 2 x° = 110°
Dividing both sides by 2, we get
x= 55°
Answer:
x = 9.9
y= 11
Step-by-step explanation:
using sin(45)21 = 29.698
3x = 29.698. Divide both sides by 3
x = 9.899. Round to 9.9
In a Right triangle with 45° angles, the legs of the 90° angle are equal. Given 21,
to find the value of y, the equation is
2y -1 = 21. Add 1 to both sides
2y = 22. Divide both sides by 2
y = 11
