Write the equation of the line that is perpendicular to the line y=(-1/5)x+9 and passes through the point (-2,-2)

Answers

Answer 1

Answer:

y = 5x + 8

Step-by-step explanation:

Recall that if two lines are perpendicular, their slopes are negative reciprocals of one another.  Thus, given y = (-1/5)x + 9, the slope of any perpendicular is

           -1

m = --------- = 5

        (-1/5)

Starting out with the slope-intercept equation y = mx + b, we get:

-2 = 5(-2) + C, or C = 8

Thus, the desired equation is

y = 5x + 8

Answer 2

The equation of the line that is perpendicular to the given line is y=5x+8.

Given that, the equation of line y=(-1/5)x+9 and passes through the point (-2,-2).

What is slope of an equation?

The slope formula is used to calculate the inclination or steepness of a line. It finds application in determining the slope of any line by finding the ratio of the change in the y-axis to the change in the x-axis.

If m is the slope of a line, then the slope of a line perpendicular to it is -1/m.

Now, slope =-1/5

-1/m = 5

Put m=5 and the point (-2, -2) in y=mx+c and simplify

That is, -2=5(-2)+c

⇒c=8

Substitute m=5 and c=8 in y=mx+c, we get y=5x+8

Therefore, the equation of the line that is perpendicular to the given line is y=5x+8.

A baking mix consists of powdered milk, sugar, and flour in a ratio of 3:4:13.
How many pounds of each ingredient do you need to make 4 lb of baking mix?

Answers

Answer:

Sugar = 0.8 lb

milk = 0.6 lb

Flour = 2.6 lb

Step-by-step explanation:

Firstly, we add the ratios = 3 + 4 + 13 = 20

For milk, we have 3/20 * 4 = 12/20 = 0.6 lb

For sugar l, we have 4/20 * 4 = 16/20 = 0.8 lb

For flour = 13/20 * 4 = 52/20 = 2.6

You will need:

[tex]Milk = 0.6 $ lb\\Sugar = 0.8 $ lb\\Flour = 2.6 $ lb[/tex]

Given:

Milk : Sugar : Flour = 3 : 4 : 13

To find the number of pounds of each ingredient required to produce 4 lb of baking mix, solve as follows:

Amount of each ingredient needed = ratio of each ingredient / total ratio value x 4 lb

Thus:

Total ratio value = [tex]3 + 4 + 13 = 20[/tex]

Amount of milk needed = [tex]\frac{3}{20} \times 4 = 0.6 $ lb[/tex]

Amount of Sugar needed = [tex]\frac{4}{20} \times 4 = 0.8 $ lb[/tex]

Amount of Flour needed = [tex]\frac{13}{20} \times 4 = 2.6 $ lb[/tex]

Therefore, you will need the follow amounts to make 4 lb of baking mix:

[tex]Milk = 0.6 $ lb\\Sugar = 0.8 $ lb\\Flour = 2.6 $ lb[/tex]

Answer:

10%

Step-by-step explanation:

We are told that To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number.

This means the total number of single digits that could possibly be a winning one is 10.

Since we are told that only 1 can be picked, thus;

Probability of winning is; 1/10 = 0.1 or 10%

Seth is making panels for a stained-glass window. He makes a triangular pane shaped like the triangle shown. Which of these rectangular panes has the same area as the triangular pane?








Help me please! I will mark brainliest whoever answers this with the right answer

Answers

Answer:

Options A and C

Step-by-step explanation:

Area of the triangular pane = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                              = [tex]\frac{1}{2}(14)(12)[/tex]

                                              = 84 cm²

Area of the rectangle is given by the formula,

Area = Length × width

Option A.

Area of the rectangular pane = 12 × 7

                                                 = 84 cm²

Option B.

Area of the rectangular pane = 15 × 7

                                                 = 105 cm²

Option C.

Area of the rectangular pane = 21 × 4

                                                 = 84 cm²

Option D.

Area of the rectangular pane = 21 × 8

                                                 = 168 cm²

Option E.

Area of the rectangular pane = 28 × 6

                                                 = 168 cm²

Therefore, rectangular panes A and C have the equal area as the triangular pane has.

Select all the true statements.
A. The smallest circle in Diego's design is congruent to the smallest circle in Elena's

B. Diego's design is congruent to Elena's design
C. Elena's design is a translation of Diego's design

Answers

The two circle designs are missing, so i have attached it.

Answer:

Options A & B are true.

Step-by-step explanation:

Congruent circles are basically identical. This means that they have the same radius and diameter but different centres.

Now, from the attached image, we see that the smallest circle in diogo's design has diameter of 2 units & radius of 1 unit while the one in Elena's design also has exactly the same measurement. Thus, we can conclude the smallest circle in diogo's design which is the first one is congruent to the smallest circle in the second design for Elena.

So option A is correct.

Looking carefully at both designs, we can observe that one is concentric while the other is eccentric. However, all the similar sized circles have the same radius & diameter. Thus, we can still say that both designs are congruent. So option B is correct.

In transformations, a translation is when all the points in a an object are made to move up or down in a state straight line in that same direction. However, the objects shape and size remains the exactly the same.

In this case, it's not so because the circle changed from concentric circles to eccentric circles. So this option C is not correct.

Use the Pythagorean theorem to find each missing length to the nearest tenth

Answers

answer: 10.4

explanation: a^2 + b^2 = c^2
plug in 3 for a and 10 for b
3^2 + 10^2 =c^2
simplify to get
109 =c^2
take the square root of both sides
c = sqrt109 or 10.44030651

Answer:

c (the hypotenuse) = 10.4 units

Step-by-step explanation:

Start off by rearranging the original pythangorean theorem (a^2+b^2=c^2) by taking the square root of both sides so it is in the form of a distance formula solving for c(the hypotenuse).

c^2 will become |c| as length cannot be negative so (labeling an absolute value is negligible)

a^2+b^2 = c^2

c^2 = a^2+b^2

√(c^2) = √(a^2+b^2)

c = √(a^2+b^2)

Then substitute the given lengths, in this scenario, sides a and b.

After you substitute, just simplify.

c = √(3^2+10^2) = √(9+100) = √109 ≈ 10.4 units (nearest tenth)
