Answer:

26 secs until reaching ground level

Step-by-step explanation:

260/10=26

Answer:

A

Step-by-step explanation:

21 yards and Total cost of $146.58

p = 1 yard

Equation: 21p = 146.58

p = 146.58/21

p = 6.98

21p=146.58 will describe the equation and the amount paid for each yard is $6.98 so option (A) will be correct.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Amount of fabric = 21 yards

Since cost per yard of fabric is given by p

So,

The total cost of fabric = Amount of fabric ×  cost per yard

146.58 = 21p

21p=146.58

Now,

p = 146.58/21 = 6.98.

Hence "21p=146.58 will describe the equation and the amount paid for each yard is $6.98".

Answer:

3 2/4

Step-by-step explanation:

1/2 is equivalent to 2/4 so you add 3 2/4 + 2 3/4 and that = 6 1/4 and its simple math from there on, 6 1/4 + 4 1/4 = 10 2/4 finally 14 - 10 2/4 = 3 2/4

5.5 miles are left to cover.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

In the morning a group of hikers hiked 3 ½ miles

and then hiked another 2 ¾ miles. then group the hiked 4 ¼ miles.

Total miles to cover = 14 miles

So, number of miles to be driven

= 14 - ( 3 ½ + 2 ¾ + 4 ¼)

= 14 - ( 7/2 + 11/4 + 17/4)

= 14- (14/4 + 11/4 + 17/4)

= 64 - 42 / 4

= 22/4= 11/2

= 5.5 miles

Hence, 5.5 miles are left to cover.

Answer:

[tex]\displaystyle y=-\frac{1}{2}x+1[/tex]

Step-by-step explanation:

The equation of any line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Two points are given: (-6,4) and (-2,2). Calculating the slope:

[tex]\displaystyle m=\frac{2-4}{-2+6}=\frac{-2}{4}=-\frac{1}{2}[/tex]

The equation of the line is, so far:

[tex]\displaystyle y=-\frac{1}{2}x+b[/tex]

To calculate the value of b, we use any of the given points, for example (-6,4):

[tex]\displaystyle 4=-\frac{1}{2}(-6)+b[/tex]

[tex]\displaystyle 4=3+b[/tex]

Solving:

b = 1

The equation of the line is:

[tex]\boxed{\displaystyle y=-\frac{1}{2}x+1}[/tex]

We can see none of the choices is correct.

Answer:

[tex]y=\frac{5}{6} x-2[/tex]

Step-by-step explanation:

Point-slope form:

where [tex](x_1, \ y_1)[/tex] are coordinates of a point that the line passes through, and [tex]m[/tex] is the slope of the line.

We are given two points that the line passes through, but we are not given the slope.

We can find the slope by using the slope formula:

where [tex](x_1, \ x_2)[/tex] and [tex](y_1, \ y_2)[/tex] are two points that the line passes through.

Substitute (-6, -7) and (6, 3) into the slope formula:

The slope of this line is 5/6. Now we are able to use the point-slope equation to find the slope-intercept equation [tex](y=mx+b)[/tex] of this line.

Substitute a point that the line passes through and the slope of the line into the point-slope equation. I'm using the point (6, 3).

Distribute 5/6 inside the parentheses.

Add 3 to both sides of the equation.

This is the equation of the line that passes through (-6, -7) and (6, 3) in slope-intercept form.

Answer:

The answer is x > -1

Step-by-step explanation:

This is because if it were a closed circle, it would have to the include the inequality -1 but since it is an opened circle, that inequality is not included. So in conclusion, Any number could be used to represent x as long as it is a greater number than -1. I hope this makes sense.

x>-1  and  x<-2 are two inequalities that would have the solution set as graphed.

a relationship between two expressions or values that are not equal to each other is called 'inequality.

x>-1  and  x<-2 are the solutions of the given graph

This is because if it were a closed circle, it would have to the include the inequality -1 but since it is an opened circle, that inequality is not included.

Step-by-step explanation:

Let's see. What is a right isosceles triangle?

A right isosceles triangle is a triangle with one right angle with at least two equal sides. In this case, it would have to be ONLY two because it has a right triangle.

What is the formula for the area of an isosceles triangle?

When y = the identical side lengths of the triangle,

and A = area,

(y × y) ÷ 2 = A

Note: Remember to compute from left to right! :)

We divide by two because when you multiple the two identical sides, you would get a square. However, we're trying to find the right isosceles triangle, and we divide by two.

Now, we can plug-in our values!

(y × y) ÷ 2 = 128

(y × y) = 64

Now, we square root both sides!

y = √64

y = 8

The length of the identical sides of the triangle is 8 meters.

[tex]\large\underline{\underline{\red{\sf \blue{\longmapsto} Step-by-step\: Explanation:-}}}[/tex]

Given that area of an isosceles triangle is 128m² .

And the triangle is right Angled ∆ .

So , the measure of sides along 90° that is perpendicular and the base will be equal .

Let us say that each of the equal sides is x .

Then , we can find the area of the triangle as ,

[tex]\boxed{\bf{\red{ Area_{triangle}=\dfrac{1}{2}\times(base)\times(height)}}}[/tex]

Now , here substitute the respective values ,

[tex]\implies \sf \dfrac{1}{2}\times(base)\times(height)=128m^2[/tex]

[tex]\sf\implies \dfrac{1}{2}\times x \times x = 128m^2[/tex]

[tex]\sf \implies \dfrac{x^2}{2}=128m^2[/tex]

[tex]\sf\implies x^2=128\times2 m^2[/tex]

[tex]\sf\implies x^2=256 m^2[/tex]

[tex]\sf\implies x=\sqrt{256m^2}[/tex]

[tex]\underline{\boxed{\red{\sf\longmapsto x=16m}}}[/tex]

Hence the value of value of identical side of the triangle is 16m .

Answer: 10⁶⁵⁰⁰⁰⁰⁷  ×  79

Answer:

it isn't obvious from your problem statement where the missing numbers are in your table. We have assumed that Barbara charges the same hourly rate for all mowing jobs, so the red numbers were the ones that were missing.

Since we know our times-8 and times-9 times tables, all the work is mental. There is nothing to show. Each number in the Dollars column is 8 times the number in the Hours column.

B) See the table on the right. Again, we know our times tables. 5*9 = 45, and so on.

C) 45 -40 = 5

Barbara earns 5 dollars more at the theme park for 5 hours' work than she does mowing lawns. (Check: The rate difference is $1 per hour, so the difference in earnings will be $5 for 5 hours.)

Hope this helps :)

Have a nice day :)

Can you give me brainliest plz :)

Answer:

25/42

Step-by-step explanation:

You can get to 25/42 by finding the least common denominator, or in layman's terms, by seeing what the lowest number the two denominators can both EQUALLY go in to. in this case it's 42, as both 6 and 7 can go into 42 equally, and 42 is the lowest number that they both can go into. So after you find the least common denominator, you make that the denominator of both fractions, and multiply the two numerators by however many times you had to multiply the denominators by. for example, to get 7 to 42, you need to multiply it by 6, so you would then multiply the numerator, in this case it's 3, 6 times, netting you 18. you do the same thing with the other fraction, since the numerators 1, you multiply it by 7, since you had to multiply 6 by 7 to get 42. this leaves you with 18/42 + 7/42, which you can now normally add together to get 25/42, and since it can't be reduced, it stays this way.
