Answer:
x=0.8712, y=1.1818
Step-by-step explanation:
1.2x+1.4y=2.7 --(1)
0.4x-0.3y=0.9--(2)
1.2x=2.7-1.4y
x=(2.7-1.4y) / 1.2 --(3)
substitute (3) in (2)
[tex]0.4(2.7-1.4y) / 1.2 -0.3y=0.9[/tex]
[tex](1.8 - 0.56y) \frac{1}{3} - 0.3y = 0.9[/tex]
times both sides with 1/3
[tex] \frac{1}{3} (1.08 - 0.56y( \frac{1}{3} ) - 0.3y = 0.9)[/tex]
1.08-0.3=0.56y+0.1y
0.78=0.66y
y=1.1818
substitute y in (3)
x=2.7-1.4(1.1818) /1.2
x=0.8712
If you know two angle measures of a triangle in spherical geometry, can you always find the measure of the third angle? Explain.
A. Yes; the angle measures of a triangle always sum to 180.
B. Yes; the angle measures of a triangle always sum to 270 in spherical
geometry.
C. No; the sum of angle measures in spherical geometry is always greater than
180, but there is not a particular number they must sum to.
D. No; the sum of angle measures in spherical geometry is always greater than
270, but there is not a particular number they must sum to.
When two angle measure of a triangle are given in spherical geometry: The sum of angle measures in spherical geometry is always greater than 180, but there is not a particular number they must sum to. Choice C (No) is correct
According to the question;
Two angle measures of a triangle in spherical geometry are given.However, unlike in plane geometry where affirmatively, the sum of angles in a triangle is equal to 180°.
In spherical geometry;
The totality of the angles of a triangle on a sphere is given as 180°(1 + 4x), where x is the fraction of the sphere's surface that is enclosed by the triangle. For any positive value of x, which in each case exceeds 180°.

Subtract 2w from both sides.
2l=48−2w
Divide both sides by 2.

48−2w
Dividing by 2 undoes the multiplication by 2.
l=
2
48−2w
Divide 48−2w by 2.
l=24−w
Answer:
14centimeters
Step-by-step explanation:
from our equation,
2l + 2w = 48
we know that the width = 10cm
so,
2l + 2( 10 ) = 48
2l + 20 = 48
2l = 48 - 20
2l = 28
divide through by 2
2l / 2 = 28 / 2
l = 14
therefore,
l = 14 centimeters

What is the slope of this line?
The slope of horizontal lines is zero because they are straight with no curve.
The slope is calculates using the rise over the run.
Rise= How many units we move up. Here we move 0 units.
Whatever the run is (NOT 0) if we divide 0 by the run, we will get 0.
Diagonal lines always have slope.

Answer:
$54196.92
Step-by-step explanation:
6900x1.0825^26
1.0825 is the multiplier
The correct answer is $54196.92.
Step by step =
6900x1.0825^26 = 54196.92.
How do you calculate the annual interest rate?
The formula and calculations are as follows:
Effective annual interest rate = (1 + (nominal rate / number of compounding periods)) ^ (number of compounding periods) - 1.For investment A, this would be: 10.47% = (1 + (10% / 12)) ^ 12 - 1.And for investment B, it would be: 10.36% = (1 + (10.1% / 2)) ^ 2 - 1.Is the interest rate annual or monthly?
The interest rate is the amount a lender charges a borrower and is a percentage of the principal of the amount loaned. The interest rate on a loan is typically noted on an annual basis known as the annual percentage rate (APR).
