Answer:

62.38

Step-by-step explanation:

1. decimal with 2 decimal places (.XX)

2. less than 100 (XX.XX)

from here, let's assign variables to our number: AB.CD

C = 1,3,5

A = 3B

D = A + B (must be less than 9)

A = 2C

with these limitations, we can extrapolate that A must be divisible by both 2 and 3. what number less than 9 has these factors? 6

A = 6

this means that B = 2 and C = 3

and, now with A and B, D = 8

so, putting them all together: AB.CD = 62.38

Answer:

Surface area = 24in

Step-by-step explanation:

I think its 6in x 4in

so like since the green cylinder is 6in i think you multiply it with the purple (sorry if I’m wrong)

Six more than the quotient of a number and 2 equals 8

ikadub [295]

Let number=x

(X/2)+6=8

First subtract 6 on each side to isolate X on one side.

(X/2)=2

Now to fully isolate X by itself, just multiply 2 on each side.

X=4

Find the missing side or angle. Round to the nearest tenth.

BartSMP [9]

Answer:

$b = 2.7$

Step-by-step explanation:

Given:

< C = 53°

< B = 80°

a = 2

Required:

Find b

Solution:

The question given suggests we are given measures for a ∆.

To find side b, which corresponds to angle B, first, we'd find angle A, which corresponds to side a, then apply the Law of sines to find side b.

=> A = 180 - (53 + 80) = 47°

Law of Sines: $\frac{a}{sin(A} = \frac{b}{sin(B}$

Plug in the values into the formula

$\frac{2}{sin(47} = \frac{b}{sin(80}$

Cross multiply

$2*sin(80) = b*sin(47)$

Divide both sides by sin(47) to make b the subject of formula

$\frac{2*sin(80)}{sin(47} = b$

$2.69 = b$

$b = 2.7$ (nearest tenth)

Which of the following is equivalent to

enot [183]

Answer:

Option (2) is correct.

$18-\sqrt{-25}=18-5i$

Step-by-step explanation:

Given expression $18-\sqrt{-25}$

We have to find an equivalence value to the expression.

Radical rule,

$\sqrt{-a}=\sqrt{-1} \sqrt{a}$

Also, $i=\sqrt{-1}$

Consider the given expression,

$18-\sqrt{-25}$

Applying radical rule to $\sqrt{-25}$

$\sqrt{-25}=\sqrt{-1}\sqrt{25}=5i$

Thus, the expression becomes,

$18-\sqrt{-25}=18-5i$

Thus, option (2) is correct.
