Answer:

n=7

Step-by-step explanation:

33-19÷2= 7

sorry if my answer is wrong

Answer:

A

Step-by-step explanation:

Remark

f and d are equal (and acute) because they are corresponding angles.

82 and f are supplementary, so we can find f

Finding f

f + 82 = 180

f = 180 - 82

f = 82

Finding d

d = f

d = 82

Answer:

The temperature on the first day was 10 °F.

Step-by-step explanation:

Let's find the temperature in every single step starting from the fourth day:

[tex]T_{4} = T_{3} - 6 F = 1 F[/tex]          

[tex] T_{3} = 1 F + 6 F = 7 F [/tex]

Then, the temperature of the third day was 7 °F

On the third day:

[tex] T_{3} = T_{2} - 10 F = 7 F [/tex]

[tex] T_{2} = 7 F + 10 F = 17 F [/tex]

Hence, the temperature on the second day was 17 °F.

Now, on the second day:

[tex]T_{2} = T_{1} + 7 F = 17 F[/tex]  

[tex] T_{1} = 17 F - 7 F = 10 F [/tex]

Therefore, the temperature on the first day was 10 °F.

I hope it helps you!                        

Answer:

x = -1

Step-by-step explanation:

Answer:

-1 = x

Step-by-step explanation:

2x - 4 = -2 + 4x

add 2 to both sides

2x - 4 + 2 = -2 + 2 + 4x

2x - 2 = 4x

subtract 2x from both sides

2x - 2x - 2 = 4x - 2x

-2 = 2x

divide both sides by 2

-2/2 = 2x/2

-1 = x

Step-by-step explanation:

f(-1) = [(-1) + 8]² + 21 = 7² + 21 = 70.

Answer:

14 weeks

Step-by-step explanation:

so from what we know she already learned one appetizer recipe so she needs to learn 42 more so what we need to do since it's three every week we need to multiply three until we are able to get 42 so three times 14 gets 42 so that means that the answer would be 14

Answer: D (none of these)

Step-by-step explanation:

Hi there!

[tex]\large\boxed{\text{x = -1, x = 0, x = 5/2, x = 3}}[/tex]

We can find the zeros of the polynomial by setting each factor equal to 0:

p(x) = 4x(x - 3)(x + 1)(2x - 5)

0 = 4x

x = 0

x - 3 = 0

x = 3

x + 1 = 0

x = -1

2x - 5 = 0

2x = 5

x = 5/2

Therefore, the zeros of this polynomial are:

x = -1, x = 0, x = 5/2, x = 3

Answer: 12.9 square km

Step-by-step explanation: 4.3 x 3 =12.9

The answer is x = 6

Let us first define x to be the number of hours of riding lessons she can take.

X = Hours of lessons

Now, she has $200, she needs to pay $20 for grooming supplies, and the lessons cost $30 an hour. We to find the maximum amount of hours of lessons she can take, so in other words, we want to make her broke. To do this, we first convert the words into an equation:

200 - 20 - 30x = 0

Simplifying, we get

180 = 30x

x=6

Answer:

B) y=2.75x

Step-by-step explanation:

2.75 is the amount the DVDs cost and x is the number of DVDs Fran buys. So it'll cost her 2.75 for every DVD she buys

The equation that correctly describes Fran lines is y = 2.75x

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Let y represent the total amount for x used DVDs.

She pays 2.75 for each DVD she buys. Hence:

y = 2.75x

The equation that correctly describes Fran lines is y = 2.75x

-2(2a-4b+3c)

Step-by-step explanation:

You have to prove that 2 angles are conguent to the other triangles angles; example: ∠A≅∠C by the additon POC (2 of those) and then one side; example: AB≅BA by the reflexive POE (1 of those)

I cant see the triangles but thats how you do them, also im learning this right now too, look up the triangle congruence things like ASA ≅ SSS≅ HL≅ exc. a chart will explain how to prove them using that:

Answer: 2√6

x² - y² can be factored as (x+y)(x-y), so we can write x² - y² = (x+y)(x-y). Plugging the values we already know for x² - y² and (x+y), we have 60 = 5√6 (x-y), so (x-y) = 60/(5√6) = 2√6.

6×+8=14 5×+2=7 14×7=98 ∆m=4.66

Given:

The data values are 4, 5, 7, 7, 7, 8, 10, 11, 11, 13, 13, 14.

To find:

The box plot for the given data set.

Solution:

The data values are

4, 5, 7, 7, 7, 8, 10, 11, 11, 13, 13, 14

Divide these values in two equal parts.

(4, 5, 7, 7, 7, 8), (10, 11, 11, 13, 13, 14)

Divide each group again in two equal parts.

(4, 5, 7), (7, 7, 8), (10, 11, 11), (13, 13, 14)

Here,

Minimum value = 4

[tex]Q_1=\dfrac{7+7}{2}=\dfrac{14}{2}=7[/tex]

[tex]Median=\dfrac{8+10}{2}=\dfrac{18}{2}=9[/tex]

[tex]Q_3=\dfrac{11+13}{2}=\dfrac{24}{2}=12[/tex]

Maximum value = 14

It means, the starting point is 4 and end point is 14 of the box plot.

Box is lies from 7 to 12 and one line inside the box at 9.

Therefore, the box plot of the given data set is shown below.

Answer:

He can buy 3 scoops of salts and 4 scoops of pepper or 4 scoops of salts and 3 scoops of pepper spent maximum.

Step-by-step explanation:

Given that:

The cost of salt = 50 cents / scoop =$ 0.5 / scoop

The cost of pepper =75 cents / scoop = $ 0.75 / scoop

Let he buys x scoops of salt and y scoops of pepper.

As he plans to bring home no more than 8 scoops of seasoning, so

[tex]x+y\leq8\cdots(i)[/tex]

The total cost of x scoops of salt and y scoops of pepper = 0.5x+0.75y

As he wants to spend less than $5, so

[tex]0.5x+0.75y<5 \\\\ \Rightarrow 50x+75y<500 \\\\\Rightarrow 2x+3y <20\cdots(ii)[/tex]

Here, [tex]x\geq 0, y \geq 0[/tex] and x,y are counting numbers.

On plotting the graph of equations (ii) and (ii), the possible solution is the integral values in the shaded as shown in the figure.

The maximum possible integral values, for expances less than $5, are (x,y)=(3,4), (4,3).

Hence, he can buy 3 scoops of salts and 4 scoops of pepper or 4 scoops of salts and 3 scoops of pepper to spent maximum.

Answer: {(0, 1), (1, 5), (2, 9)}

Step-by-step explanation:

Given linear equation: y-1=4x which can be rewritten as

y=4x+1

To find the set which represents possible inputs and outputs of the function. Let's check all the options

A. {(1, 4), (2, 8), (3, 12)}

at x=1

y=4(1)+1

⇒y=5≠4

Thus this set is not the required set.

B. {(4, 1), (8, 2), (12, 3)}

at x=4

y=4(4)+1

⇒y=16+1=17≠1

Thus this set is not the required set.

C.{(0, 1), (1, 5), (2, 9)}

at x=0

y=4(0)+1

⇒y=1

Thus this set is the required set represents possible inputs and outputs of the function.

D. {(1, 0), (5, 1), (9, 2)}

at x=1

y=5≠0

Thus this set is not the required set.
