If 30cents are out then net income=100-30=70

ratio:-

\\ \rm\Rrightarrow \dfrac{30}{70}

\\ \rm\Rrightarrow \dfrac{3}{7}

\\ \rm\Rrightarrow 3:7

Work out the m and c for the line<br> y=x+6
VARVARA [1.3K]

Answer:

m - 1

c - 6

Step-by-step explanation:

y=x+6\\\\

The equation is in slope-intercept form.

y = mx + c

m - slope

c (or b) - y -intercept

Usually if the slope is one it will not be written.

y = 1x + 6  

The slope is one.

6 takes 'c's place, so it is the y-intercept.

Hope this helps.

Today's cafeteria specials at a high school in Somerville are a deluxe turkey sandwich and a
umka2103 [35]

The cost of turkey sandwiches is $3 and chef salads costs $2.

 Two equations can be derived from this question:

12t + 44s = 124 equation 1

12t + 58s = 152  equation 2

Where:

t = turkey sandwiches

s = chef salads

In order to determine the value of s, the following steps would be taken:

Subtract equation 1 from 2

14s = 28

Divide both sides of the equation by 14

s = $2

Substitute for s in equation 1

12t + 44(2) = 124

12t = 88 = 124

12t = 124 - 88

12t = 36

t = 3

which number is the largest 1.2x10 to the forth power,4.5x10 to the negitive third power,3.8x10 to the third power,7.5x10 to the
Dennis_Churaev [7]

Answer:

2 × 10 to the fourth power. (160,000)

Step-by-step explanation:

We know that if it is a negative exponent that is also an odd number, it will not be the greatest/largest. 2 times 10 is 20 and then 20 to the fourth power is 160,000. 3.8 times 10 equals 38, then we put it to the third power and we will get 54,872. Finally, 7.5 times 10 equals 75 and when we put that to the third power, it becomes 421,875. Therefore, 2 times 10 to the fourth power is the greatest/largest.
