Answer: oh god

Step-by-step explanation:

Answer:

y = 7x - 8

Step-by-step explanation:

The equation of a line in slope-intercept form is: y = mx + b, where m is the slope and b is the y-intercept.

The problem already gives us both of these values:

m = 7

b = -8

All we have to do is plug them in:

y = mx + b

y = 7x + -8

y = 7x - 8

Thus, the answer is y = 7x - 8.

Answer:

Step-by-step explanation:

area = length * width

area = (x - 6) (x - 10)

area = x (x - 10) - 6 (x - 10)

area = x^2 -10x -6x -10

area = x^2 -16x -10

Answer:

option 1

as the sides were already given, A and D are the only way that the triangle can have SAS.

The option 1 . ∠A ≅ ∠D is correct and needed to apply SAS similarity theorem in this given condition.

The  SAS theorem states that if two triangles have a congruent angles and the sides that define the angle  are proportional, the two triangles are similar.

Given are two triangles ΔABC and ΔDEF and their sides AB =7 , AC = 12, DE =14, DF = 24

Then AB/ DE = 7/14 = 1/2

 and AC / DF = 12/24 = 1/2

∴ AB / DE = AC/ DF

Therefore the sides AB and AC are proportional to DE and DF

And for the application of SAS the angle defined by these pairs must be congruent.

AB and AC defines ∠A and DE and DF defines ∠D

Thus, ∠A must  be congruent to  ∠D so that SAS can be to applied to make the given triangles similar.

Therefore, option 1. ∠A ≅ ∠D  is correct option

Answer:

The local newspaper has 250 readers in total

Step-by-step explanation:

Given that

Letter to the editor = 10

Also it is given that 10 is the 4% of total readers of the newspaper.

Let x be the number of readers of the newspaper

It can be written as:

[tex]10 = 4\%\ of\ x[/tex]

Converting the percentage into decimal

[tex]10 = 0.04x\\\frac{10}{0.04} = \frac{0.04x}{0.04}\\x = 250[/tex]

The newspaper has 250 readers.

Hence,

The local newspaper has 250 readers in total

Answer:

The correct answer to the question is;

1 < x < 4

Step-by-step explanation:

The give parameters are;

ΔABC is an isosceles triangle, with the vertex angle = 35° + 20° = 55°

Therefore, the two base angles are 62.5° each by definition of isosceles triangle

Given that the angle subtended by  4·x - 4 which is 25° is lesser than the angle subtended by the 12 unit side length which is 35° we have;

4·x - 4 < 12

4·x < 12 + 4

∴ 4·x < 16

x < 16/4

x < 4

Therefore, the range is 1 < x < 4

Answer:

a. There is nothing wrong with Mary's reasoning b. 2 water lilies.

Step-by-step explanation:

a. This is because, she reasons that if she doubles the amount of water lilies she buys, it would take half the time it takes to produce 10,000 lilies. So, there is nothing wrong with Mary's reasoning.

b. Since it takes 1 water lily to produce 10000 lilies in 20 days, 1 water lily will produce x lilies in 10 days.

So, x = 10000 × 10/20 = 5000 lilies

So, 1 water lily produces 5000 lilies in 10 days.

So, x water lilies will produces 10000 lilies in 10 days.

So x = 10000 × 1/5000 = 2 water lilies

So, 2 water lilies will produce 10000 lilies in 10 days.

So, Mary needs 2 water lilies so she can meet her goal of having the pond surface covered in 10 days.

Answer:

If 60% of a number is 90.

Suppose that the number is N.

60% of that number can be written as:

(60%/|00%)*N = 0.6*N = 90

Now we can solve that for N

0.6*N = 90

N = 90/0.6 = 150.

for the second part, we have that:

% of a number is 180, what is the 150%?

We do not have the first percentage, so i could not really answer this, so lets do it in a general way.

A% of a number N, is equal to 180.

(A%/100%)*N = 180

(A/100)*N = 180

Then:

N = 180*(100/A).

Now we want to compute the 150% of this number, this will be:

(150%/100%)*N

0.15*N = 0.15*180*(100/A). = 0.15*18,000/A = 2,700/A

Where A will depend on the first percentage.

Answer:

90 centimetres per day

Step-by-step explanation:

Given that:

One of the Bamboo species growth can be seen.

Growth in [tex]\frac{1}{3}[/tex] of a day = 30 cm

To find:

The growth per day in centimetres as a proper fraction, mixed number or whole number.

Solution:

If we are given that:

The growth of a bamboo tree is [tex]y[/tex] centimetres in [tex]x[/tex] number of days.

Then growth per day can be found by dividing the total growth of bamboo tree by the number of days.

Formula can be written as:

Growth per day = [tex]\frac{y}{x}[/tex]

We are given that:

[tex]y = 30\ cm\\x = \frac{1}{3}\ days[/tex]

Putting the values, we get:

[tex]\dfrac{30}{\frac{1}3}\\\Rightarrow \bold{90\ cm}[/tex]

Answer:

∠KYR = 43 degrees

Step-by-step explanation:

1. We know that the entire angle equals to 90 degrees because it is a right angle.

First you have to find the value of c and to do this, you add the values of both angles and make it equal to 90

3c + 64 + 5c + 82 = 90]

8c + 146 = 90

     - 146     -146

8c = -56

c = -7

Now we have to find the value of angle KYR so just plug in -7 for c

3(-7) + 64 = 43
