Step-by-step explanation:

First find the missing leg of the right triangle.

Two integers a and b have a product of -33. What is the least possible sum of a and b

irga5000 [103]

The number -33 divisors are:

D(-33) = {-33, -11, -3, -1, 1, 3, 11, 33}

a × b = -33

2) -11 × 3 = -33 ⇒ Sum is: -11 + 3 = -8

3) -3 × 11 = -33 ⇒ Sum is: -3 + 11 = 8

4) -1 × 33 = -33 ⇒ Sum is: -1 + 33 = 32

6) 3 × (-11) = -33 ⇒ Sum is: 3 + (-11) = 3 - 11 = -8

7) 11 × (-3) = -33 ⇒ Sum is: 11 + (-3) = 11 - 3 = 8

8) 33 × (-1) = -33 ⇒ Sum is: 33 + (-1) = 33 - 1 = 32

<h2>The least possible sum of a and b is -32</h2>

Digiron [165]

Answer:

About 11.299 hours.

Step-by-step explanation:

To solve this problem, you can set up an equation to model the decay of the medicine. Let's call the time that medicine has been in the body x.

$(1-0.0595)^x=0.5$

$0.9405^x=0.5$

Taking the log x of both sides, you get

$x=\log_{0.9405} 0.5$

$x\approx 11.299$ hours. Hope this helps!

FInding the length of EB

larisa86 [58]

Answer:

EB=3.3

Step-by-step explanation:

From the diagram, triangle ABC is similar to triangle DBE.

This means that, the corresponding sides are proportional.

It was given that AC=6, DE=4, CB=5.

We want to find EB=x

Since the ratio of corresponding sides are proportional, we have:

$\frac{EB}{CB} =\frac{ED}{AC}$

We substitute to obtain:

$\frac{x}{5} =\frac{4}{6}$

Multiply both sides by 5 to get:

$x=\frac{4}{6}\times 5=\frac{20}{6}=\frac{10}{3}=3.3$
