Yesterday, between noon and midnight, the temperature dropped by 28.4°F. If the temperature was -1.9°F at midnight, what was it at noon?

Answers

Answer 1

Answer:

n= 26.5

Step-by-step explanation:

Comment

You need some sort of formula for this question. But you more or less have to invent it.

Formula

Temperature midnight = noon - temperature drop

Givens

temperature drop = 28.4

temperature midnight = -1.9

Temperature noon = x

Solution

-1.9 = x - 28.4                       Add 28.4 to both sides

-1.9 + 28.4 = x-28.4+28.4    Combine

Answer

26.5 = x

It is a method for determining the value of a single unit by subtracting the value of multiple units and subtracting the value of multiple units from of the value of a single unit.

The value of many items is given in the unitary method, and we must either determine the worth of more or fewer items. To do so, we must first determine the value of one item by division and then determine the value of more as well as fewer items by multiplication.

Now, for the given question;

It takes Heidi 12 minutes to walk 2/3 miles.

Applying the unitary method.

Then, for in 1 minutes Heidi will walk = 2/(3×12).

For walking in 1 hour or 60 min =  (2×60)/(3×12).

BIRDHOUSES Ebony can build 0.7 birdhouse in 1 day. How many birdhouses can she build in 10 weeks?

Answers

Find 10 weeks in days:
1 week = 7 days
10 weeks = 70 days
70 days * 0.7 birdhouses
= 49 birdhouses

Step-by-step explanation:

0.7 birdhouses in 1 day.

how many in 10 weeks ?

for that we need to know how many days are in 10 weeks.

1 week = 7 days

assuming that she is working on the birdhouses also on weekends, that means 10 weeks = 10×7 = 70 days.

and that means she can build

0.7 × 70 = 49 birdhouses in 10 weeks.

now, if she works only Monday to Friday on the birdhouses, then that means

1 week = 5 days

and 10 weeks = 10×5 = 50 days.

and that means she can build

0.7 × 50 = 35 birdhouses in 10 weeks.

if there is really no other information about that, I would use the usual 7 days per week and the first solution (49).

Answer:

I believe its graph 4 (not sure though, you can plug in some values to make sure)

Step-by-step explanation:

Say you are given the graph of the line y = -x. Write the equation of the line that is perpendicular to the given line and goes through the point (-8, 2).

Answers

Key ConceptsPerpendicular linesLinear equationsSlope-intercept form

Linear equations are often organized in slope-intercept form: [tex]y=mx+b[/tex]

m = slopeb = y-intercept

To find a linear equation, we often first solve for the slope, and then solve for the y-intercept algebraically.

To find the slope of a perpendicular line, we must find the negative reciprocal of the slope of the reference line.

Solving the Question

We're given:

Reference line is [tex]y=-x[/tex]Perpendicular line passes through  [tex](-8,2)[/tex]

1) Find the slope of the reference line

We can rewrite the reference line to be clearer in slope-intercept form:

[tex]y=-1x+0[/tex]

This means that -1 is the slope.

2) Find the slope of the perpendicular line

The negative reciprocal of -1 is 1. Therefore, the slope of the perpendicular line is 1. Plug this into slope-intercept form:

[tex]y=x+b[/tex]

3) Solve for the y-intercept of the perpendicular line

[tex]y=x+b[/tex]

Plug in the given point (-8,2) and solve for b:

[tex]2=-8+b\\b=2+8\\b=10[/tex]

Therefore, the y-intercept of the perpendicular line is 10. Plug this back into our original equation:

Which of the following ordered triples is the solution to the system of equations?

2x − y − z = −1

3x + y − z = 2

x + y − 5z = −8

Answers

Answer:

1,1,2

Step-by-step explanation:

The solution to the given system of equations are:{ x = 1, y = 1, z = 2} which is the corrrect answer would be option (A).

What is an equation?

The equation is defined as a mathematical statement with at least two terms that contain variables or values that are equal.

We have been given the system of equations as:

2x − y − z = −1

3x + y − z = 2

x + y − 5z = −8

Isolate the term of x in the equation 2x − y − z = −1, and we get

x = (- 1 + y +z)/2

Substitute the value of x = (- 1 + y +z)/2 in the above both equations,

3(- 1 + y +z)/2 + y − z = 2

(- 1 + y +z)/2 + y − 5z = −8

Simplify the equation to you get,

(5y + z - 3) / 2 = 2

(3y - 9z - 1) / 2 = -8

Isolate the term of y : (5y + z - 3) / 2 = 2 ⇒ y = (-z +7 )/5

Substitute the value of y = (-z +7 )/5 in the equation (3y - 9z - 1) / 2 = -8

(3(-z +7 )/5 - 9z - 1) / 2 = -8

Simplify the equation to you get,

8(-3z + 1)/d = -8

Isolate the term of z : 8(-3z + 1)/d = -8 ⇒ z = 2

Substitute the value of z = 2 in the equation y = (-z + 7) / 5 to simplify to get

⇒ y = 1

Substitute the values of y = 1 and z = 2 in the equation x = (-1 + y + z) / 2 to simplify to get

⇒ x = 1

The solution to the given system of equations are:

What is a translation?

A translation is a geometric transformation when each point in a figure, shape, or space is moved in a specific direction by the same amount. A translation can also be thought of as moving the coordinate system's origin or as adding a constant vector to each point.

In this case, it can be seen that the shape was rotated counterclockwise twice. That's 90° × 2 = 180°
