Answers

Answer 1

Answer: This problem can solve by the rule of three:
275 miles---------------9 gallons
x---------------------------1 gallons.

x=(275 miles * 1 gallons) / 9 gallons=28.55555.... miles≈28.56 miles.

Answer: 28.56 miles.

Which is bigger, 40% of 180 or ¼ of 320?

Answers

'of' in mathematics means multiplication.

40% of 180 means 40/100 * 180

40/100 * 180
= 0.40 * 180
= 72

1/4 of 320 means 1/4 * 320

1/4 * 320
= 320/4
= 80

40% of 180 is 72
1/4 of 320 is 80

1/4 of 320 is bigger than 40% of 180

You could also say that as:

1/4 of 320 is greater than 40% of 180.

Write the slope-intercept form of the equation of the line through the given point with the given slope. through: (-5, -1); slope = negative 3 over 5

Answers

Answer:

The slope-intercept form of the equation of the line is $y = -(3)/(5) \cdot x -4$ .

Step-by-step explanation:

We know that the slope-intercept form of the equation of the line is represented by:

$y = m\cdot x + b$

Where:

$x$ - Independent variable, dimensionless.

$y$ - Dependent variable, dimensionless.

$m$ - Slope, dimensionless.

$b$ - y-Intercept, dimensionless.

From statement we find that $m =-(3)/(5)$ . If $x = -5$ and $y = -1$ , the value of the y-intercept is:

$-1 =-(3)/(5)\cdot (-5)+b$

$-1 = 3 + b$

$b = -4$

The slope-intercept form of the equation of the line is $y = -(3)/(5) \cdot x -4$ .

What is the value of fg(7)

Answers

Answer:

fg(7) = 231

Step-by-step explanation:

The question is asking you to find fg(7), which is function of f times function of g when x = 7. To solve it, you just need to plug in the 7 where x is in both equation and then multiply these results.

f(x) = x + 4

f(7) = 7 + 4

= 11

g(x) = 3x

g(7) = 3(7)

= 21

fg(7) = 11 × 21 = 231
