Answer:

The answer is 7,000 meters

Step-by-step explanation:

because you do 67*100 which equals to 6,700 and then u round it which makes it equal to 7,00 meter

Answer:

120 meters (approx)

Step-by-step explanation:

Think of the rectangle like two triangles;

if we find the hypotenuse of one, then we know the length of the rectangle across

Remember the Pythagorean theorem:

a^2 + b^2 = c^2

where a and b are the sides of the triangle

so then substitute in the known values:

a = 100

b = 67

now solve

100^2 + 67^2 = c^2

14489 = c^2

sqrt(14489) = c

120.37 = approx c

Answer:

a) 18

b) 18 : 12

c)3  : 4

Step-by-step explanation:

a) 30 × [tex]\frac {60}{100}[/tex]

= 18 students walk to school

b)             No. of students                                       No. of students

            who walk to school               :                 who walk to school

                        18                               :                                 12

c)

18 : 12

=18/6 : 12/3

=3  : 4

Answer:

Step-by-step explanation:

6x-10x^2+3-(5x^2+3x-4)

when there is a - in front of an expression in (), change the sign of each term in the expression

6x-10x^2+3-5x^2-3x+4

now collect like terms

3x-10x^2+3-5x^2+4

3x-15x^2+3+4

3x-15x^2+7

now use the commutative property to reorder the terms

-15x^2+3x+7

=-15x^2+3x+7

Answer:

Answer: 93 3/5

Step-by-step explanation:

3/5 + 3/5 + 3/5 = 9/5

9/5 + 9/5 = 18/5 = 3 3/5

15 x 6 = 90

90 + 3 3/5 = 93 3/5

Answer:

x=-5

Step-by-step explanation:

y-2=(7/6)(x-1)

y=(7/6)x+5/6

using y =-5

-5=(7/6)x+5/6

-35/6=(7/6)x

x=-5

Answer:

Slope-intercept equation.

Step-by-step explanation:

y = mx + b

66 degrees

Thing you have to know for these types of problems: The total measure of all angles is 180 degrees.

With that in mind, if we add 83 and 31, we get 114 degrees.

Now subtract from 180 and you will get 66 degrees.

Answer:

It will take the master baker 2.86 hours to finish the remaining order after 2 hours.

Step-by-step explanation:

the time taken for the master baker to fill the order = 6 hours

the time taken for the student baker to fill the order = 8 hours

let the time taken for both to finish the work together if they work at the same rate = x

[tex]\frac{x}{8} + \frac{x}{6} =1\\\\\frac{3x + 4x}{24} = 1\\\\7x = 24\\\\x = \frac{24}{7}\\\\x = 3.43 \ hours[/tex]

After 2 hours, the remaining time for them to finish the work together is given by;

t(remaining) = 3.43 hours - 2 hours = 1.43 hours

Working at the same rate, 2 persons will take 1.43 hours to finish the remaining work.

One person will take hour many hours ?

2 persons working at the same rate  --------> 1.43 hours

1 person working at the same rate -----> ?

= 2 x 1.43 hours

= 2.86 hours

Therefore, it will take the master baker 2.86 hours to finish the remaining order after 2 hours.

Answer:

$156.86

Step-by-step explanation:

To calculate tip, you need to multiply the total bill by the percent tip you are going to leave. In this case the bill is $136.40, and the customer is going to leave a 15% tip. So, you would want to move the decimal place over to the left by 1, which you should get 13.64 as your number. Then divide it in half, which should give you 6.82. Now add 13.64 and 6.82 with the original bill price. If you don't add the 13.64 you would've forgotten the 10% part of the tip. At the end you should get $156.86 as your final bill.
