What is the a50 of -4, 1,6, 11

Answers

Answer 1

is:

an = a1 + (n-1)d

Where:
n is the term number (n = 1, 2, 3, ...)
an is the nth term in the sequence
a1 is the first term in the sequence = -4
d is the common difference
To find the common difference, subtract any two successive terms: 1 - (-4) = 5, 6 - 1 = 5, 11 - 6 = 5. So we have d = 5. Hence the explicit form for this sequence is:

an = -4 + (n-1)5

To find a50, set n = 50 in the above formula and compute the answer.

a bag contains 300 balls. 96 balls are yellow. Which answer shows both the correct proportion and the correct percent of yellow balls in the bag.

Answers

The proportion of yellow balls in the bag is 8/25 and percentage is 32 %

What is Percentage and Proportion?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

The number of balls in the bag = 300

The number of yellow balls in the bag = 96

The proportion of yellow balls =
The number of yellow balls in the bag / The number of balls in the bag

The proportion of yellow balls = 96 / 300

= 24 / 75

= 8 / 25

Therefore , The proportion of yellow balls in the bag is 8 / 25

Now ,

The percentage of yellow balls in the bag =
Number of yellow balls in the bag / Number of balls in the bag x 100 %

The percentage of yellow balls in the bag = ( 8 / 25 ) x 100 %

= 8 x 4 %

= 32 %

Hence ,

The proportion of yellow balls in the bag is 8/25 and percentage is 32 %

Answers

Answer:

7 hamsters at 5 pesos each and 13 hamsters at 8 pesos each

Step-by-step explanation:

5x + 8y = 139

x + y = 20

x = 20 - y

5x + 8y = 139

5(20 - y) + 8y = 139

100 - 5y + 8y = 139

100 + 3y = 139

3y = 139 - 100

3y = 39

3y/3 = 39/3

y = 13

x + y = 20

x + 13 = 20

x = 20 - 13

x = 7

We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.

ax^2 + bx + c

a=4

b=-9

c=2

you can try it by hand or use this:

https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php

you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)

so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis

4/5 + 7/10 = 1 1/2 ....... true, so we have (10 * 1 1/2) = 15

2 1/2 - 1 5/6 = 1/6 ...... false, so we do not add anything.

The rental rate for a power washer has a one time fee of $60 plus $20 for each day of the rental. The graph shows the points representing the total cost of the rental.

Write an equation, in slope-intercept form(y = mx + b) that models the total cost of the rental over time.

ALOT OF PTS

Answers

The equation of the rental rate in slope-intercept form(y = mx + b) that models the total cost of the rental over time is; C = $20t + $60.

The slope intercept form of a linear equation takes the form; y = mx + c.

In this scenario;

The one-time fee, $60 represents the y-intercept of the rental rate equation.

The daily charge, $20 represents the slope of the rental rate equation.

Ultimately, the rental rate equation is; C = $20t + $60

(0, 4) represents the y-intercept ⇒ b = 4

Calculate the slope between the two points: [tex]m = \frac{y_{2} -y_{1}}{x_{2} -x_{1}} = \frac{4-1}{0-2} = -\frac{3}{2}[/tex]

Find the equation of the line, whose slope is 5 and x- intercept is 2

Answers

Answer:

Step-by-step explanation:

when x intercept is points given, then y = 0

So far, you have y = 5x + b where b = the yintercept

x = 2

y = 0

0 = 5x + b

0 =5 * 2 + b

0 = 10 + b Subtract 10 from both sides.

-10 = b

Equation: y = 5x - 10
