The members of a school club sold sweatshirts for $15 each. They made $960 in sales. The equation 15x = 960 can
be used to determine x, the total number of sweatshirts they sold.
Which number line best represents the total number of sweatshirts they sold?

Answer:

See below.  Veronica's thinking is incorrect.  I've included what she is thinking, but the correct thinking is more useful, as noted below.

Step-by-step explanation:

I don't know what Veronica is thinking, other than:

(398 x 18) = (400*18 - 18)

She should be thinking:

(398 x 18) = (400 x 18) - (2*18).  The "2" is for the two extra groups of 18 that she will have when multiplying 400 x 18, instead of 398 x 18.

Answer:

$9.60

Explanation: Take the 24 ounces and divide that by 16 to get 1.5 pounds. Then multiply 6.40 by 1.5 and you get the answer of $9.60

Answer:

[tex]\huge\boxed{\sf y = 3}[/tex]

Step-by-step explanation:

Given that:

[tex]\displaystyle y \propto \frac{1}{x}[/tex]

Converting proportionality into equality

[tex]\displaystyle y = \frac{k }{x}[/tex]   ------------------------- (1)

We know that:

y = 18 when x = 4

Put in Eq. (1)

[tex]\displaystyle 18 = \frac{k}{4} \\\\Multiply \ 4 \ to \ both \ sides\\\\18 \times 4 = k\\\\72 = k\\\\ \boxed{k = 72}[/tex]

Now,

y = ? when x = 24

Put in Eq. (1)

[tex]\displaystyle y = \frac{72}{24} \\\\\boxed{y = 3}[/tex]

The balloon’s vertical distance above the ground is 860.0 ft

Right angle triangle are triangle that has one of its sides as 90 degrees. The side of the triangle can be found using trigonometric ratios. Therefore,

The horizontal distance from the landmark tot he hot balloon is 1579 feet and it is the hypotenuse side of the triangle formed. Therefore, the vertical height is the opposite sides.

Using trigonometric ratio,

sin 33° = opposite / hypotenuse

sin 33° = x / 1579

cross multiply

x = 1579 × sin 33

x = 1579 × 0.54463903501

x = 859.985036289

x = 860.0 ft

-192 × f = 48

f = 48/-192 = -1/4

here it seems to be clear now that your teacher starts counting at a1 (and not a0).

a1 = -192

a2 = a1 × -1/4 = -192 × -1/4 = 48

a3 = a2 × -1/4 = a1 × -1/4 × -1/4 = -192 × 1/16 = -12

an = -192 × (-1/4)^(n-1)

a6 = -192 × (-1/4)⁵ = -192 × -1/1024 = 3/16

It is asking for the intercept.

y = x + 3 becomes y - x = 3

multiply it by two, so it becomes -2x + 2y = 6. Then add it to the other equation, and solve for y.

2x + 4y = 60

(2x + 4y) + (-2x + 2y) = 60 +6

6y = 66

y = 11

Plug in the known y into the the easiest equation.

11 = x +3

x = 8

Intercept: (8, 11)

We can conclude the following about the box plots:

Median is the middle value which is represented by a vertical line that divides the rectangular box in a box plot.

Median for Group A is smaller than the median of Group B.

Range of a data set is the difference between the maximum value and the minimum value. Range is a measure of variability. The bigger the range, the more the variability and vice versa.

Range of Group A is larger than range of Group B.

  f(0) = 243 . . . cats at the start

Step-by-step explanation:

The exponential function tells you the number of cats after t years is ...

  f(t) = 243(1/3)^t

When t=0, the exponential factor is 1, so the value of the function is the multiplying constant.

  f(0) = 243

This means there were 243 stray cats in town when the animal control program started.

Answer:

D. 7.5 inches

Step-by-step explanation:

So, we can find the ratio of the big triangle to the small one by dividing the values of the hypotenuse.

So, 18/6 = 3

Big:small = 3:1

So, using this we can make an equation to find AD.

Let's say ED=x.

AD is basically ED (x) + AE (5).

Since ED is part of the small triangle, and AD is part of the big one, we can use the 3:1 ratio from above.

So, [tex]\frac{x+5}{x}[/tex]=3.

Multiply both sides by x, getting x+5 = 3x.

Subtract the x:                            -x        -x

And you get 5=2x, giving you 2.5 = x.

However, we're not done yet, as 2.5 is the value of ED, but we need AD.

Remember, AD is = ED + AE.

So, AD = 2.5 + 5.

Finally, AD =  7.5

WIDTH ‘W’ = 8 in; LENGTH = 11 in AND HEIGHT = 6 in

Step-by-step explanation:

VOLUME = (W+3)*(W-2)*W = 52

W*(W^2 +W - 6) = 525

SOLUTION BY TRIAL & ERROR

TRIAL 1 : LET W = 5; 5(25+5–6) = 120

TRIAL 2 : LET W=10; 10(100+10–6) = 1040

TRIAL 3 : LET W = 8; 8(64+8–6) = 528 OK

ANSWER WIDTH ‘W’ = 8 in; LENGTH = 11 in AND HEIGHT = 6 in

9

Step-by-step explanat

Answer:

Equation 1 matches with number 9.

Equation 2 matches with number 7.

Equation 3 matches with number 1.

Equation 4 matches with number 3.

Equation 5 matches with number 5.

Step-by-step explanation:

Equation 1:  −9x > −9

−9x > −9

Divide both sides by −9.

-9x/-9 = -9/-9

Since −9 is negative, the inequality direction is changed.

x < 1

x < 1 matches with the graphed solution of number 9.

So, Equation 1 matches with number 9.

Equation 2: 2x + 6≥ −2

2x + 6≥ −2

Step 1: Subtract 6 from both sides

2x + 6 − 6 ≥ −2 − 6

2x ≥ −8

Step 2: Divide both sides by 2

2x/2 ≥ −8/2

Step 3: Simplify

x  ≥  -4

x  ≥  -4 matches with the graphed solution of number 7.

So, Equation 2 matches with number 7.

Equation 3: x − 9 < −5

x − 9 < −5

Step 1: Add 9 to both sides.

x − 9 + 9 < −5 + 9

Step 2: Simplify

x < 4

x < 4 matches with the graphed solution of number 1.

So, Equation 3 matches with number 1.

Equation 4: −6x < −12

−6x < −12

Divide both sides by -6

-6x/-6 < -12/-6

Since −6 is negative, the inequality direction is changed

x > 2

x > 2 matches with the graphed solution of number 3.

So, Equation 4 matches with number 3.

Equation 5: -7x + 20 > 55

-7x + 20 > 55

Step 1: Subtract 20 from both sides.

−7x + 20 − 20 > 55 − 20

Step 2: Simplify

−7x > 35

Step 3: Divide both sides by -7.

-7x/-7 > 35/-7

Step 4: Simplify

x < -5

Since −7 is negative, the inequality direction is changed

x < -5 matches with the graphed solution of number 5.

So, Equation 5 matches with number 5.
