Answer:

B. x = 7, y = 4√2

Step-by-step explanation:

Drop a vertical from the upper left corner

This creates a rectangle and a 45-45-90 triangle

The bottom of the rectangle is 3

The legs of the triangle are 4

Therefor

x = 4 + 3

x = 7

For a 45-45-90 triangle

the hypotenuse = leg * √2

y = 4√2

Answer:

x = -9°

m∠A = 37°

Step-by-step explanation:

(8-5x) + (10-3x) = 90

8-5x + 10-3x = 90

18-8x = 90

-8x = 72

x = -9°

m∠A = 10- (-9*3) =

10-(-27) = 37°

What is the product of 7/16 and -6/13 I will make you the brainlest

mr_godi [17]

Answer:

$\frac{7}{16} *\frac{-6}{13} = \frac{-42}{208}$

Step-by-step explanation:

$\frac{7}{16} *\frac{-6}{13} = \frac{-42}{208}$ . First multiply 7*-6=-42.

Then do 16*13=208.

Simplify by dividing both by 2.

You get $\frac{-42}{208}=\frac{-21}{104}$ .

Your final simplified answer is $\frac{-21}{104}$

I hope this helps!

Vase: $34.99
Shipping: $ 3.00
+__________
$37.99

Then calculate sales tax by multiplying $37.99 x 0.0825 -
Above Total: $37.99
Sales Tax Rate: $ 0.0825
x__________
$ 3.1341
You round down because ^ less than five (five or above you would round up)

Levart [38]

Answer:

D. $y = 5\cdot \Sigma_{i=0}^{4} \left(\frac{1}{3} \right)^{i}$

Step-by-step explanation:

Let be $y = \Sigma_{i = 0}^{4} \left[5\cdot \left(\frac{1}{3} \right)^{i}\right]$ . To find the equivalent expression we must use the following property:

$y = c\cdot \Sigma_{i = 0}^{n} p(x) = \Sigma_{i=0}^{n} [c\cdot p(x)]$ (1)

Based on this fact, we find the following equivalence:

$y = 5\cdot \Sigma_{i=0}^{4} \left(\frac{1}{3} \right)^{i}$

Hence, the correct answer is D.
