A bag contains 25 kg of flour. A baker used 80% of it to bake bread. How much flour,in kg,remained ?​

Answers

Answer:

5 kg flour remains

Step-by-step explanation:

80% of the original 25 kg comes to 0.80(25 kg), or 20 kg.  We convert 80% to its decimal equivalent, 0.80, to get this result  

The amount of flour remaing is then (1.00 - 0.80)(25 kg), or 0.20(25 kg) = 5 kg.

5 kg flour remains.

Answer:

25 - 20 = 5 kg

Steps:

25×80/100 = 25×8/10 = 200/10 = 20 kg

25 - 20 = 5 kg

27.1% of city employees ride the bus to work. This is up 47% from last year. What percent of employees rode the bus to work last year?

Answers

Answer:

18.44%

Step-by-step explanation:

Let :

Percentage who rode bus to work last year = x

Percentage who ride bus to work this year = 27.1%

Percentage who ride bus to work this year = [percentage who rode bus to work last year + 47% of percentage who rode bus to work last year]

Mathematically ;

27.1% = x + 47% of x

0.271 = x + (0.47x)

0.271 = x + 0.47x

0.271 = 1.47x

x = 0.271 / 1.47

x = 0.1843537

x = 0.1843537 * 100%

x = 18.435%

x = 18.44%

Length of TV is 12π in. The diameter is?

Answers

Answer:

Diameter = 54 units

Step-by-step explanation:

Given:

Angle θ = 80'

Length of arc TV = 12π

Find:

Diameter

Computation:

Length of arc = [θ/360][2πr]

So,

12π = [80/360][2πr]

54 = 2r

r = 27

Diameter = 2r

So,

Diameter = 54 units

Answers

Answer:

16

Step-by-step explanation:

sin = adjacent ÷ hypotenuse.

sin 45 = x ÷ 23

0.71 = x ÷ 23

0.71 × 23 = x

x = 16.26

~ 16.

Answer:

Step-by-step explanation:

using the Pythagorean theorem     a² + b² = c²

in this triangle a = x and b = x  so   x² + x²  = c²       c is the hypotenuse

         

                 x² + x²  = c²

                   2x² = c²             since c = 23 solve for x

                     x² =  c² / 2

                     x   =  ± √(c² / 2)

                     x   =  ± √(23² /2)

                          = ± √(529 /2)            

                          = ± √(264.5)            

                          =  16.26          x can't be negative

        That is correct but it doesn't answer the question

                 x = ??? / √xx

           sin 45  = √2 / 2  which equals    x / 23

                      √2 / 2  =    x / 23

                       x =  23 (√2 / 2)

                          =  23 (√2)  / 2             divide the √2 numerator and demenator

                          =  23 (√2)/√2 / (2 / √2)

                           = 23 / (2 / √2)

A salesman earns 7% commission on all the merchandise that he sells. Last month he sold $6000 worth of merchandise. How much commission (in dollars) did he earn last month?

Answers

Answer: $420

Step-by-step explanation:

Percentage on commission earned = 7%

Amount of merchandise sold = $6000

Amount of commission earned = Percentage on commission earned × Amount of merchandise sold

= 7% × $6000

= 7/100 × $6000

= 0.07 × $6000

= $420

He earned $420 as commission last month.

Step-by-step explanation:

The law of function would be shown below:

Let us assume that the amount charged by the taxis of this company is equivalent to y.

And, x is the amount of kilometers traveled.

So as per the given statement, the taxi charged $5 plus $1.50 per km

Therefore the law of function would be

y = 5 + 1.5x.

Carolyn was asked to solve the following system of equations. Her work is shown.

What error did Carolyn make? Identify her mistake and explain the error.


1. Carolyn did not subtract 4 from both sides of the equation.

2. Carolyn did not distribute the -2 to both terms

3. Carolyn did not substitute x + 2 for y

4. Carolyn did not substitute 3 for x to find the value of y for the solution

Answers

Answer:

Carolyn did not distribute the -2 to both terms

Step-by-step explanation:

This was how Carolyn solved the second step:

[tex]3x-2(x+2)=7\\3x-2x+4=7[/tex]

She did multiply both terms in the parentheses by 2, but she did not change the sign for the 4. It should instead be -4 since a negative number multiplied by a positive number will always make a negative number.

Here is the correct way of solving it:

[tex]3x-2(x+2)=7\\3x-2x-4=7[/tex]

find the zeros of the quadratic equation-
v(5v-7)=0

Answers

Answer:

Step-by-step explanation:

v(5v-7)=0

We multiply parentheses

5v^2-7v=0

a = 5; b = -7; c = 0;

Δ = b2-4ac

Δ = -72-4·5·0

Δ = 49

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

v1 = −b−√Δ/2a

v2 = -b+√Δ/2a

√Δ = √49 = 7

v1 = -(−7)−7/2*5 = 0/10 = 0

v2 = -(−7)+7/2*5 = 14/10 =  1+2/5
