Dale has a special deck of cards. Each card has a different rational number on it. The cards are 0.25, 4/5, 2/9, 0.48, and 8/11. How many cards have a value that is greater than ½?

Answer:

x=-0.5

Step-by-step explanation:

the question is -9=18x

we divide both sides by 9

-1=2x

divide both sides by 2

x=-0.5

Answer:

36 Quarters and 3 dimes

Step-by-step explanation:

4 x 9 = 36

10 x 3 + 30

Answer:

28 quarters and 23 dimes

Step-by-step explanation:

q = d + 5

.25a +.1d = 9.30

.25(d+5) +.1d = 9.30

.25d + 1.25 +.1d = 9.30

.35d = 8.05

d = 23

23 + 5 = 28

q = 28

Answer:

3y - x = 3

Step-by-step explanation:

The slope intercept form of the equation is expression is y = mx+c

m is the slope

c is the y inercept

From the graph

c = 1

Using the coordinates (-3, 0) and (0, 1)

m = 1-0/0-(-3)

m = 1/3

Get the required equation

y = 1/3x + 1

Multiply through by 3

3y = x + 3

3y - x = 3

Hence the required equation is 3y - x = 3

Answer:

-3

Step-by-step explanation:

Note the right side of the equation. There is a negative sign outside of the parenthesis. Distribute the negative sign to all terms within the parenthesis:

x + 3 = - (-x + __)

x + 3 = x - ___

Note:

1) When multiplying a negative and positive together, the answer will be negative

2) When multiplying a negative and negative together, the answer will be positive:

x + 3 = x - ___

Note the equal sign, this means that the two side of the equation must equal. This means that the only answer choice is -3:

x + 3 = x - (-3)

x + 3 = x + 3 (True)

Answer:

[tex]Scale = \frac{2}{3}[/tex]

Step-by-step explanation:

To solve this question, I'll use the coordinates of SV and S'V' as points of reference.

From the attachment:

[tex]S = (3,6)[/tex]

[tex]V = (15,3)[/tex]

[tex]S' = (2,4)[/tex]

[tex]V' = (10,2)[/tex]

First, calculate distance SV

Distance formula is:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

For SV:

[tex]d_1 = \sqrt{(15 - 3)^2 + (3 - 6)^2}[/tex]

[tex]d_1 = \sqrt{(12)^2 + (-3)^2}[/tex]

[tex]d_1 = \sqrt{144 + 9}[/tex]

[tex]d_1 = \sqrt{153}[/tex]

For S'V'

[tex]d_2 = \sqrt{(10 - 2)^2 + (2 - 4)^2}[/tex]

[tex]d_2 = \sqrt{64 + 4}[/tex]

[tex]d_2 = \sqrt{68}[/tex]

The scale factor is then calculated using:

[tex]Scale = \frac{S'V'}{SV}[/tex]

[tex]Scale = \frac{d_2}{d_1}[/tex]

Substitute values of d1 and d2

[tex]Scale = \frac{\sqrt{68}}{\sqrt{153}}[/tex]

[tex]Scale = \sqrt{\frac{68}{153}}[/tex]

[tex]Scale = \sqrt{\frac{1}{2.25}}[/tex]

[tex]Scale = \frac{1}{1.5}[/tex]

Express as a proper fraction

[tex]Scale = \frac{1*2}{1.5*2}[/tex]

[tex]Scale = \frac{2}{3}[/tex]

Answer:

25/64

Step-by-step explanation:

To get this answer, first you need to use the distributive property:

(-3/8)(-5/8) - (1/4)(-5/8)

Next, multiply:

15/64 - (-5/32)

Change the negative signs into a positive sign:

15/64 + 5/32

Multiply 5/32 by 2 on both top and bottom:

15/64 + (5)(2)/(32)(2)

You will then get:

15/64 + 10/64

Now, add the numerators. You will get:

25/64

This is your answer. I hope it helped!

Answer: 4(5 + 4)

Step-by-step explanation:  Both 16 and 20 are multiples of 4, so factor out 4 and  leave the remaining factors in parentheses

4*5 + 4*4  becomes

4(5 + 4) add  inside parentheses

4(9)  multiply to check

4 × 36

same as adding 20 + 16 = 36

Answer:

The equation is f = z - x

Step-by-step explanation:

The equation is

Given that

The total cost + online fee for one ticket is $32.25

Let us assume f be the cost of ordering each ticket online

Cost of each ticket be x = $24.95

And, the total cost = z = $32.25

Now the equation would be

x + f = z

So for f it would be

f = z - x

Given:

The graph of set of ordered pairs.

To find:

The domain of the set of number.

Solution:

Domain is the set of input values or x-values.

From the given graph it is clear that the set of ordered pair is:

{(1,2), (2,4), (3,1), (4,6), (5,4), (6,5)}

Here, the x-values are 1, 2, 3, 4, 5, 6. So, the domain is the set of these values.

Domain = {1, 2, 3, 4, 5, 6}

Therefore, the correct option is A.

Answer:

(a) 1.18

(b) 99.71

Step-by-step explanation:

to know the value of q in degrees we can use cosine of q

[tex]\cos (q) = \frac{OR}{OQ}\\\\\cos (q) = \frac{5}{13}\\\\q = \cos^{-1}(\frac{5}{13})\\\\q \approx 67.38[/tex]

now to radians

the formula is

[tex]x\times\frac{2\pi}{360}\\\\[/tex]

with x the degrees

[tex]67.38\times \frac{2\pi}{360}\\\\=\frac{67.38\pi}{180}\\\\\approx 0.374\pi\\\\\approx 1.18[/tex]

so the measure of angle q is 1.18 radians

so now for part b

[tex]A = \frac{r^2 \alpha }{2}\\\\[/tex]

with [tex]\alpha[/tex] being the central angle in radians

for degrees is the following

[tex]A = \frac{\theta}{360}\times \pi r^2[/tex]

so we have

[tex]A = \frac{13^2 (1.18)}{2}\\\\A = 99.71[/tex]cm^2

Answer:

The answer is 125 eggs.

The total number of eggs required will be 125.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that a restaurant keeps eggs in a rack that has 5 layers. Each layer has 5 rows, with 5 eggs in each row. The number of eggs will be calculated as:-

Number of eggs = 5 x 5 x 5

Number of eggs = 125

Therefore, the total number of eggs required will be 125.

Answer:

Cost of one rocket = $1.5

Step-by-step explanation:

Given:

6 rockets and 11 bombs cost = $36.50

14 rockets and 8 bombs cost = $41

Find:

Cost of one rocket

Computation:

Cost of one rocket = x

Cost of one bomb = y

So,

6x + 11y = 36.50.....eq1

14x + 8y = 41......eq2

From eq1

y = [36.50 - 6x]/11

From eq2

14x + 8y = 41

14x + 8[36.50 - 6x]/11 = 41

x = 1.5

Cost of one rocket = $1.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

4 (x + 3) = 2x + 8   <----"four times the sum of a number and three is equal to eight more than twice the number."

Second, we want to solve the equation:

4 (x + 3) = 2x + 8

4x + 12 = 2x + 8

2x + 12 = 8       <-------subtract 2x from both sides of the equation.

2x = -4              <-------subtract -12 from both sides

x = -2                <-------divide both sides by 2 which leaves a negative answer

Third, we want to check the answer by substituting the value of -2 for x in the original equation.

4 (x + 3) = 2x + 8

4 (-2 +3) = 2(-2) + 8

-8 + 12 = -4 + 8

  4        =      4

4 (x + 3) = 2x + 8   <----"four times the sum of a number and three is equal to eight more than twice the number."

Second, we want to solve the equation:

4 (x + 3) = 2x + 8

4x + 12 = 2x + 8

2x + 12 = 8       <-------subtract 2x from both sides of the equation.

2x = -4              <-------subtract -12 from both sides

x = -2                <-------divide both sides by 2 which leaves a negative answer

Third, we want to check the answer by substituting the value of -2 for x in the original equation.

4 (x + 3) = 2x + 8

4 (-2 +3) = 2(-2) + 8

-8 + 12 = -4 + 8

  4        =      4

Answer:

No x-intercept/Zero

Step-by-step explanation:

f(x)=3x(3/4)x-4

To find x-intercept/zero, substitute f(x)=0

0=3x(3/4)x-4

To raise a fraction to a power, raise the numerator and denominator to that power

0=3x 3 x-4/4 x-4

Calculate the product

0=3 x-3/4 x-4

Since the right-hand side is always positive, the statement is false for any value of x

Since there is no solution for f(x)=0, there is no x-intercept/Zero

Answer:

$23,077

Step-by-step explanation:

Let the minimum amount you want to earn be represented as x

Therefore

6.5% of x = $1,500

6.5/100 × x = $1500

6.5x/100 = $1500

Cross Multiply

6.5x = $1500 × 100

x = $1500 × 100/6.5

x = $23076.923077

Approximately to the nearest dollar= $23,077

Therefore, the minimum amount he needs to sell in order to earn $1,500 if he earns a 6.5% commission on everything he sells is $23,077
