Answer:

$the \: slope \: is \to \boxed{-3} \\ the \: y \: intercept \to \boxed{18}$

Step-by-step explanation:

$the \: solpe \: \boxed{m} = \frac{9 -1 2}{3 - 2} = -3 \\ y = mx + c \\ 12 = (-3)(2) + c \\ c = 12 + 6 = 18$

The linear equation is
slope-intercept form y=-3x+18
standard form 3x+y=18

slope is -3

y intercept is (0,18)

Ayden earned a grade of 89% on his multiple choice history final that had a total of

Genrish500 [490]

Answer:

178

Step-by-step explanation:

Method 1: Set up a proportion

Set up an equation of the form:

\frac{\color{red}{\text{part}}}{\color{orange}{\text{whole}}}=

whole

part

\,\,\frac{\color{blue}{\text{percent}}}{100}

100

percent

Assign the variable xx to the unknown value:

\color{red}{x}=

\,\,\color{red}{\text{part}}

part

The question asks what \textit{part}part of the total questions is 89%

Substitute the known values with the numbers given in the problem, and the unknown value with xx:

\frac{\color{red}{x}}{\color{orange}{200}}=

200

\,\,\frac{\color{blue}{89}}{100}

100

Solve for xx:

100\cdot\color{red}{x}=

100⋅x=

\,\,\color{orange}{200}\cdot\color{blue}{89}

200⋅89

Cross multiply

\frac{100x}{100}=

100

100x

\,\,\frac{17800}{100}

100

17800

Divide both sides by 100

178

Simplify

Method 2: Convert to decimal and multiply

{89}{100}=0.89

89%=

100

=0.89

Move decimal 2 places to the left

{Multiply result by the total:}

Multiply result by the total:

0.89{200}=

0.89⋅200=

Find the area of sector AOB. Express your answer in terms of pi and rounded to the nearest tenth.

STatiana [176]

63 $\pi$

The sector is $\frac{70}{360}$ ; there are 360 degrees in a circle.
You use the formula $\pi r^{2}$ .
18cm is the radius, and then you square it to get 324.
Multiply 324 by $\frac{70}{360}$
You get 63 $\pi$

Rose is fishing from a small boat. A fish swimming at the same depth as the hook at the end of her fishing line is 8 meters away

tensa zangetsu [6.8K]

The question is incomplete, as the depth of the hook isn't given in the question. However, using a proposed depth for the hook, we could give a stepwise solution to the exercise.

Answer:

Kindly check explanation

Step-by-step explanation:

If given a hook depth of 6 meters, and a distance of 8 m(fishing line from hook) at the the Same depth, then the distance between rose and the fish, x can be calculated, using the relation.

Hypotenus² = opposite² + adjacent²

(refer to attached picture)

x² = 6² + 8²

x² = 36 +. 64

x² = 100

x = sqrt(100)

x = 10 meters

You can use the actual depth value to obtain the actual solution to your question.
