Answer:

its 94 on deltamath just did it

Step-by-step explanation:

Let t=0 represent the year 1997

Starting Value: 690

Write function:

y=690(b)^t

Now find the b-value:

y=390 when t=4 (2001−1997)

390=690(b)^4

390/690=690(b)^4/690

0.56521739=b^4

(0.56521739)^1/4=(b^4)^1/4

0.86706944=b

Write Complete Function:

y=690(0.86706944)^t

Find value in 2011 (use t=14):

y=690(0.86706944)^14

y=93.67062063

y≈94

Answer:

Systematic

Step-by-step explanation:

Samples may be classified as:

Convenient: Sample drawn from a conveniently available pool.

Random: Basically, put all the options into a hat and drawn some of them.

Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.

In this question:

Every xth element, so systematic.

Answer:  x+(x+1)+(x+2) = 63

This is because x is the smallest number, so x+1 is the next value up, and x+2 is the value after that. The parenthesis are optional. I used them to separate out the three expressions. We can simplify the left side to 3x+3, which means that equation in bold is the same as 3x+3 = 63. So there are few ways we can form the equation.

You have the correct answers for the other boxes:

20+21+22 = 63

Nice work.

20, 21, 22

Step-by-step explanation:

Let x = the smallest integer of the three consecutive ones

(x + 1) = the next consecutive integer after x

(x + 2) = the next consecutive integer after (x + 1)

The sum of these three should add up to 63 so

x + (x + 1) + (x + 2) = 63

This simplifies to

3x + 3 = 63

Solving for x, we get

x = 20

Therefore, the three consecutive integers whose sum add up to 63 are 20, 21 and 22.

Answer:

Total Cost in a day is . Profit function is . And the revenue function is . In a day, bookstore must sell at least 15 books, because of 6n-90=0, in order to make profit.

Step-by-step explanation:

-90

The break-even point for this bookstore is 15, i.e. correct answer is,

C. n = 15.

Here, we have,

given that,

A bookstore costs $90 a day to keep open,

and it spends $12 for each book that it sells.

If each book sells for $18,

now, we know that,

Breakeven quantity = fixed cost / price – variable cost per unit

now, we have,

$90 / (18 - 12)

=$90 / $6

= 15

so, n = 15

Hence, The break-even point for this bookstore is 15, i.e. correct answer is, C. n = 15.

Answer:

A. Parallelogram

Step-by-step explanation:

The given points are;

(-10, -4), (-7, -8), (-5, -4), (-2, -8)

Let 'A' represent the point (-10, -4), let 'B' represent the point (-7, -8), let 'C' represent the point (-5, -4), and let 'D' represent the point (-2, -8), we have;

The (horizontal) distance between points A and C = -5 - (-10) = 5

The (horizontal) distance between points B and D = -2 - (-7) = 5

Therefore;

The length of [tex]\overline {AC}[/tex] = The length of [tex]\overline {BD}[/tex]

The length of [tex]\overline {AB}[/tex] = √((-10 - (-7))² + (-4 - (-8))²)) = 5

The length of [tex]\overline {CD}[/tex] = √((-5 - (-2))² + (-4 - (-8))²)) = 5

∴ The length of [tex]\overline {AB}[/tex] = The length of [tex]\overline {CD}[/tex]

[tex]\overline {AC}[/tex] is parallel to the horizontal axis

[tex]\overline {BD}[/tex] is parallel to the horizontal axis

∴ [tex]\overline {AC}[/tex] ║ [tex]\overline {BD}[/tex]

Given that [tex]\overline {AB}[/tex] = [tex]\overline {CD}[/tex], then [tex]\overline {AB}[/tex] ║ [tex]\overline {CD}[/tex]

Therefore, the quadrilateral ABCD is a parallelogram

(The angle ∠ABD = 180 - arctan (4/3) ≈ 126.9 > 90, therefore, the parallelogram ABCD is not a rectangle.)

Answer:

X²=(24)²+(7)²

x²=576+49

x²=625

×=25

Answer:

25

Step-by-step explanation:

Use the Pythagorean Theorem: a²+b²=c²

a=24

b=7

c=x

Plug in the numbers

(24)²+(7)²=x²

Square 24 and 7

576+49=x²

Add 576 and 49

625=x²

Take the square root on both sides

x=√625

Simplify

x=25

Answer:

39

Step-by-step explanation:

By linear pair angles and exterior angle theorems:

[tex]x \degree + (180 - 98) \degree = 180 \degree - (31 + 28) \degree \\ \\ x \degree + 82 \degree = 180 \degree -59\degree \\ \\ x \degree + 82 \degree = 121\degree \\ \\ x \degree = 121\degree - 82 \degree\\ \\ x \degree = 39 \degree\\ \\ x = 39[/tex]

Answer:

$52

Step-by-step explanation:

Given data

Price of blender= $65

Coupon = 20%

Let us find the amount of the coupon

=20/100*65

=0.2*65

=$13

Hence the amount of the coupon is $13

The total price Nathan pays is

=65-13

=$52

Answer:

[tex]y =\frac{4}{5}x-6[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y =mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (5,-2) and (15, 6)

[tex]=\frac{6-(-2)}{15-5}\\=\frac{6+2}{15-5}\\=\frac{8}{10}\\=\frac{4}{5}[/tex]

Therefore, the slope of the line is [tex]\frac{4}{5}[/tex]. Plug this into [tex]y =mx+b[/tex]:

[tex]y =\frac{4}{5}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y =\frac{4}{5}x+b[/tex]

Plug in one of the given points and solve for b

[tex]6=\frac{4}{5}(15)+b\\6=12+b[/tex]

Subtract 12 from both sides of the equation to isolate b

[tex]6-12=12+b-12\\-6=b[/tex]

Therefore, the y-intercept of the line is -6. Plug this back into [tex]y =\frac{4}{5}x+b[/tex]:

[tex]y =\frac{4}{5}x-6[/tex]

I hope this helps!

Answer:

Addition: -1 + -3 = -4

Subtraction: (-4) - 5 = -10

Step-by-step explanation:

Since adding a positive makes a negative number stay negative, it equals -4.

Then by subtracting a negative with a positive (5), the number stays negative once again, which then equals -10.

Answer:

she needs to sell 55 posters

Step-by-step explanation:

Answer:

0 pints ≤ J ≤ 4 pints

Where J is the amount of juice that Carl bought.

Step-by-step explanation:

Here we need to learn how to use the inequality symbols.

Let's define each one of them:

A < B   (A is strictly smaller than B)

A > B  (A is strictly greater than B)

A ≤ B (A is smaller than or equal to B)

A ≥ B  (A is greater than or equal to B)

A ≠ B  (A is different than B)

Ok, in this case, we know that Carl buys 4 one-pint cartons of milk.

Then the total amount of mil that he buys is 4 times one pint, this is:

4*1 pint = 4 pints

He has 4 pints of milk.

And we know that he buys less juice than milk, then if J represents the amount of juice that he bought, we need to have:

J < 4 pints

This means that the amount of juice that he bought is smaller than the quantity of milk that he bought (4 pints)

If we want to be more correct, we should write:

0 pints ≤ J ≤ 4 pints

Here we say that J needs to be a positive number (we can't buy a negative quantity of juice)
