Answer:

1) 18

2) 30

3) 6

4) 3000

5) 5

Explanation:

1

25+15+20=60

x/60 = 60/100

x/60 = 3/5

x= 60(3/5)

x=36

50% of 36 is 18

2

x/48 = 75/100

x/48 = 3/4

x= 48(3/4)

x=30

3

x/30 = 60/100

x/30 = 3/5

x = 30(3/5)

x = 6

4

rate = boxes per day per person

r = 1500/4/6

r=62.5

62.5 = x/6/8

500 = x/6

3000 = x

5

rate = task per day per worker

r = 1/7/5

r=0.02857142857

0.02857142857 = 1/x/7

0.2 = 1/x

0.2x = 1

x = 0.2

1/0.2 = 5

Identify the values of m and b of the linear function y = mx + b, graphed below. ​
Varvara68 [4.7K]
<h2>Finding the slope and y-intercept of a line given the graph</h2><h3>Answer:</h3>

b = 4

m = -\frac{1}{3}

<h3>Step-by-step explanation:</h3>

An equation of a line written in its Slope-intercept Form, y = mx +b, has b as its y-intercept and m as its slope.

b or the y-intercept is the y-coordinate when x = 0. On the given line, we can see that when x = 0, y = 4. It's y-intercept is the point (0,4) so b = 4.

The slope, m, of the line can be calculated by \frac{y_2 -y_1}{x_2 -x_1}\\ where x_n and y_n is the xy-coordinates of any point n on the line. In the given line, we can see that (5,3) is on the line so this can be point 1. (0,4) is also on the line (yes, you can also use the y-intercept in calculating the slope of the line) so this can be our point 2.

m = \frac{4 -3}{0 -3} \\ m = \frac{1}{-3} \\ m = -\frac{1}{3}

The y-intercept is b = 4 and the slope is m = -\frac{1}{3}

Rosita invested in a precious mineral. The value of the mineral tends to increase by about 12% per year. She invests $24,000 in
Lerok [7]

Answer:

The Rosita investment worth in 2025 is $83486.4 .

Step-by-step explanation:

The expontential increase function is given by.

y = a(1 + r)^{t}

Where a is the initial value , r is the rate of interest in the decimal form and t is the time.

As given

Rosita invested in a precious mineral.

The value of the mineral tends to increase by about 12% per year.

She invests $24,000 in 2014.

As

a = 24000

12% is written in the decimal form.

= \frac{12}{100}

= 0.12

r = 0.12

As Rosita invested from 2014 to 2025.

Than

t = 2025 - 2014

t = 11 years

Put in the expontential increase function.

y = 24000(1 + 0.12)^{11}

y = 24000(1.12)^{11}

y = 24000 × 3.4786 (Approx)

y = $83486.4

Therefore the Rosita investment worth in 2025 is $83486.4 .
