Answer:

$20

Step-by-step explanation:

First we will change the ratio so that we are finding how much money Siti receives to the total amount of money.

$4:3 \rightarrow 4:(3+4)=4:7$

Now we can solve for how much money Siti receives using a proportion.

$\frac{4}{7} = \frac{\mbox{money Siti receives}}{35}$

We can see that the denominator increases 5 times, so the numerator must increase 5 times too. This means Siti receives $20.

coldgirl [10]

The amount or the strength of force is named magnitude.

<h3>What is force?</h3>

Force is that the push or pull on an object with mass that causes it to alter its velocity. Force is an external agent capable of adjusting the state of rest or motion of a selected body. it's a magnitude and a direction.

<h3 /><h3>How to identify strength of force?</h3>

The term which is true is magnitude. The magnitude of a force is expressed within the SI unit of force called Newton. 1 Newton is that the force which might make an object of 1 kilogram mass to at a speed of 1 meter per second. Magnitude is essentially the most extent of size and also the direction of an object. Magnitude is employed as a typical think about vector and scalar quantities. Magnitude of earthquake is measured by Richter scale.

Hence the number or the strength of force is named its magnitude.

Convert 12 1/2% into a decimal (It isn't 12.50)<br>Convert 12 1/2% into a fraction (It isn't 25/2)

Hoochie [10]

Answer:

0.125 and 1/8

Step-by-step explanation:

To convert a percentage to a decimal, divide by 100 to move 2 decimal places to the left.

12.50% / 100 = 0.125

To convert a percentage into a fraction, rewrite the decimal number you got and put it over 1. Multiply the numerator and denominator by 1000 to move 3 decimal places to the right and get your fraction.

$\frac{0.125}{1}$ · $\frac{1000}{1000}$ = 125/1000

Divide the numerator and denominator by the GCF, 125, to get your simplified fraction.

125/125 = 1

1000/125 = 8

125/1000 = 1/8

Michael earns $900 per month, plus 5% commission on all his sales over $750. what is the minimum amount of sales Michael must ha

Alina [70]

<h3>The minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000</h3>

<em><u>Solution:</u></em>

<em><u>The expression to Michael earnings is:</u></em>

$b + (c \times s)$

Where,

b is the base salary, which is $ 900 in this sum

c is the commission rate

Given that commission rate is 5%

s is the sales

Michael must have to earn at least $2500 in a month

Here, at least means, "greater than or equal to" 2500

The inequality is framed as:

base salary + 5 % on sales $\geq$ 2500

$900 + \frac{5}{100} \times s \geq 2500\\\\\ 900 + 0.05s\geq 2500$

Solve the inequality

$0.05s\geq 2500-900\\\\0.05s \geq 1600\\\\Divide\ both\ sides\ by\ 0.05\\\\s\geq 32000$

Thus, minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000

when a car speed is 24 km/hr a journey takes 80 minutes what must the speed be for the same journey to take 60 minutes?

Mariana [72]

Answer:

32 km/ hr

Step-by-step explanation:

Given that :

Speed of car = 24km/ hr

Time taken =. 80 minutes = 80 / 60 = 1.33333 hours

The distance traveled :

Speed * time

24 km/hr * 1.333333 = 32 km

Speed required to complete 32 km. Journey in 60 minutes = 1 hour

Speed = distance / time

Speed = 32 km / 1 hour

Speed = 32 km/ hr
