#1.
Here what you do is cross multiply.
$\frac{8x}{13x}$
#2.
Same as #1, just cross multiply.
$\frac{9x}{12}$

You get the gist?

Suppose you want to get a loan for $ 5 , 000 at an interest rate of 5.3 % for 2 years to be paid back in 24 monthly installments

swat32

Answer:

monthly payment = $56.445

Step-by-step explanation:

given data

loan = $5000

interest rate r = 5.3 % = 0.053

time t = 2 year = 24 months

solution

we will use here amount of the monthly payments formula that is

monthly payment = principal × $\frac{r}{1+(1-r)^{-t}}$ ................1

put here value and we get

monthly payment = 5000 × $\frac{0.053}{1+(1-0.053)^{-24}}\\$

monthly payment = $56.445

Which expression is not equivalent to the other three?

Kitty [74]

The right answer is B.

The first step to answering this question is combining all like terms.

A. 2x + 2 + 2x + 3x - 8
The like terms in this expression are the x terms and the constants
So, what you would do is combine all of the x terms and combine all of the constants

(2x + 2x +3x) + (2 - 8)
7x - 6

B. 4 + 7x - 2
In this expression, you would combine all of the constants

7x + (4 - 2)
7x + 2

C. -2 + 5x + 2x - 4
For this expression, you would again, combine all of the x terms and all of the constants.

-2 + 5x + 2x - 4
(5x + 2x) + (-2 - 4)
7x - 6

D. 8x - x - 6
For this expression, you would combine all of the x terms

8x - x - 6
(8x - x) - 6
7x - 6

Now let's look at all of the new answer choices:
A. 7x - 6
B. 7x + 2
C. 7x - 6
D. 7x - 6

The question is asking you to find the one expression that's different. The only different one is B, so that's the answer.

You need to use this formula:
([a]/[sinA])=([c]/[sinC])-I am going to use 'a' for the x, and 'c' for 16(square root of 3)
Now its just getting 'a' by itself.
([c] times [sinA])/([sinC])=[a]
[c]=16 square root of 3
sinA=sin(60)=(square root of 3)/2
sinC=sin(90)=1

Plug it in to get 24 for a, or x. Do the same to figure out y with the new sides.
The final y is:
8 square root of 3
Final answer is C.

Wet N' Dry camp provides water-based activities and ground sports activities for a

wolverine [178]

Answer:

x+y≤80; x≥8; y≥5
see attached for a graph
Twenty campers are doing water-based activities and 40 campers are doing ground-based activities.

Step-by-step explanation:

1. Let x and y represent the numbers of campers doing water- and ground-based activities, respectively.

x + y ≤ 80 . . . . . . a maximum of 80 campers can be accommodated

x ≥ 8 . . . . . . . . . . a minimum of 8 campers should be water-based

y ≥ 5 . . . . . . . . . . a minimum of 5 campers should be ground-based

2. See the attachment for a graph. Possible outcomes are shaded red. The boundary lines of the shaded area are included in the possible outcomes.

3. Twenty campers are doing water-based activities and 40 campers are doing ground-based activities.
