Answer:

Step-by-step explanation:

so (+35) can be written as 35 because it's automatically already positive. +(-33) can be written as -33 because of one negative sign and one positive sign (if it was two negative or two positive, it would be positive). it's the same as 35-33, and 35-33=2.

You have $90,000 for investment. You will invest S dollars in stocks and B dollars in bonds. You expect a 10% return on stocks a

SIZIF [17.4K]

The dollar amount for the return on stocks is $3375 and the dollar amount for the return on bonds is $1125.

Two equations can be derived from the question:

s + b = $90,000 equation 1

0.1s + 0.02b = $4500 equation two

$4500 = 0.05 x $90,000

The above equation is a simultaneous equation and it would be solved using the elimination method.

The following steps would be take to determine the value of b

Multiply equation 1 by 0.1

0.1s + 0.1b = 9000 equation 3

Subtract equation 2 from 3

0.08b = $4500

b = $56,250

The following step would be taken to determine the value of s

Substitute for b in equation 1

s + $56,250 = $90,000

$90,000 - $56,250 = s

s = $33,750

Dollar amount for the return on stocks = $33,750 x 0.1 = $3375

Dollar amount for the return on bonds = $56,250 x 0,02 = $1125

From base camp, a hiker walks 3.5 miles west and 1.5 miles north. Another hiker walks 2 miles east and 0.5 miles south. To the n

levacccp [35]

Answer:

The hikers are 5.9 miles apart.

Step-by-step explanation:

Let O represents the base camp,

Suppose after walking 3.5 miles west, first hiker's position is A, then after going 1.5 miles north from A his final position is B,

Similarly, after walking 2 miles east, second hiker's position is C then going towards 0.5 miles south his final position is D.

By making the diagram of this situation,

Let D' is the point in the line AB,

Such that, AD' = CD

In triangle BD'D,

BD' = AB + AD' = 1.5 + 0.5 = 2 miles,

DD' = AC = AO + OC = 3.5 + 2 = 5.5 miles,

By Pythagoras theorem,

$BD^2 = BD'^2 + DD'^2$

$BD = \sqrt{2^2 + 5.5^2}=\sqrt{4+30.25}=\sqrt{34.25}\approx 5.9$

Hence, the hikers are 5.9 miles apart.

A spinner can land on either red, blue, green, or yellow (the wedges are the same size). you spin twice. what is the probability

melisa1 [442]

There are four (4) colors to choose from. The number of sample space is equal to 4. With the condition given in this item, the probability of landing on blue on the first spin is equal to 1/4. Similarly, the probability of landing on yellow on the second spin is 1/4.

P = (1/4)(1/4)

P = 1/16

Answer: 1/16
