x + y = 4(1 + y) + y = 4 1 + 2y = 4 1 - 1 + 2y = 4 2y = 4 y = 2

-x = -1 + y-x = -1 +2
-x = 1
.... that's as far I can go... sorry

Sal Boxer decided to divide a gift of $5000 into two different accounts. He placed $1000 in an account that earns an annual simp

mash [69]

Answer:

THE TOTAL INTEREST EARNED = $ 385

Step-by-step explanation:

Interest earned by sal from first account can be calculated as follows :

Principal value (P) = $1000 .

interest rate (R) = 7.5 % .

Time period (T) = 1 year .

$\textbf{S . I} =\frac{\texbf{P * R * T}}{\textbf{100}}$

$= \frac{1000 * 7.5 * 1}{100}$

= $ 75 .

SIMILARLY , we can find the intrest earned by rest amount.

Principal value (P) = $5000 - $ 1000 = $ 4000 .

Interest rate (R) = 7.75 % .

Time period (T) = 1 year .

$S . I = \frac{4000 * 7.75 * 1}{100}$

= $ 310 .

THE TOTAL INTEREST EARNED = $ 75 + $ 310

= $ 385

Circle Center Formula: (x - h)² + (y - k)² = r²

(h, k) is center
r is radius

Step-by-step explanation:

Step 1: Define

Identify

(h, k) = (8, 10)

r = 6

Step 2: Find Equation

Substitute in variables [Center Circle Formula]: (x - 8)² + (y - 10)² = 6²
Evaluate exponents: (x - 8)² + (y - 10)² = 36

PLZZZZZZZ HELPPPP

dolphi86 [110]

Answer:

The correct option is 1.

Step-by-step explanation:

It is given than the area of the triangle ABC is 46cm².

Area of a triangle is

$A=\frac{1}{2}\times base\times height$

Base of the triangle is AB and height of the triangle is CD.

$A=\frac{1}{2}\times AB\times CD$

$A=\frac{1}{2}\times AB\times 8$

$A=4\times AB$

The area of the triangle is 46cm².

$46=4\times AB$

$AB=\frac{46}{4}$

$AB=11.5$

Therefore the length of side AB is 11.5 cm. Option 1 is correct.
