How many acute angles does a heptagon have?

Answer:

6 minutes

Step-by-step explanation:

Given

Leo = 36 sec / rev

Stan = 40 sec/rev

Required

Determine the time (in minutes) they'll meet again

We start by getting the multiples of 36 and 40 uptil we get a common multiple.

Leo: 36 = 36, 72, 108, 144, 180, 216, 252, 288, 324, 360, .....

Stan: 40 = 40, 80, 120, 160, 200, 240, 280, 320, 360....

From above, the common multiple is:

Common Multiple = 360

This means that they'll meet at 360 seconds

Convert to minutes

360 sec = 360/60 mins

360 Seca = 6 mins

Hence,it will take them 6 minutes to meet again at the starting point

c=√(25²+28²)= 37.5

Answer:

Step-by-step explanation:

[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

(3, 4)    ⇒   x₁ = 3,  y₁ = 4

(7, -4)    ⇒   x₂ = 7,  y₂ = -4

So the slope:

                    [tex]\bold{m=\dfrac{-4-4}{7-3}=\dfrac{-8}4=-2}[/tex]

2 is the slope of the passing through points (3,4) and (7,-4).

The slope of a line is a number that describes both the direction and the steepness of the line.

Given that a line is passing through the points  (3,4) and (7,-4).

Slope = ([tex]y_{2}[/tex] - [tex]y_{1}[/tex])/([tex]x_{2}[/tex] - [tex]x_{1}[/tex])

Therefore, slope = (-4-4)/(7-3) =-8/-4 = 2

Hence, 2 is the slope of the passing through points (3,4) and (7,-4).

Answer: I hope I got it right. You can mark brainliest if you want. I don't really care.

Step-by-step explanation:

Well, it seems that for every week, Pragitha swims x + 2 laps. So if she swims x + 2 laps twice, she will get 2x + 4. So x is equal to 4. You add that four and you get three x. So for one week, she swims x + 2 laps and for the second lap, she swims 2x + 4. Which according to the table, is equal to 3x. So for 3 weeks, she clearly swims less, because maybe she's tired or something. So it's 2x+1. And for week 4, it's week one and week 2 combined.

Answer:

Percentage: 115%

Decimal: 1.15

Fraction: [tex]\frac{23}{20}\\[/tex]

Step-by-step explanation:

Percentages, Fractions, and Decimals

Assume we set 100% as the original price of the food that Michael consumed. When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

Now we express 115% as a decimal, simply dividing by 100:

115% = 115/100 = 1.15

To express it as a fraction, we simplify the division instead of calculating it:

115% = [tex]\frac{115}{100}[/tex]

Simplifying by 5:

115% = [tex]\frac{23}{20}[/tex]

Step-by-step explanation:

Answer:

Total cost= 15.25*[(12*3)/8]

Step-by-step explanation:

The expression would be:

Total cost= 15.25*[(12*3)/8]

Prove:

Number of slices= 12 people*3 slices

Number of slices= 36

Number fo pizzas= number of slices/8

Number of pizzas= 36/8

Number of pizzas= 4.5 = 5 pizzas

Now, the total cost:

Total cost= number of pizzas*unitary cost

Total cost= 5*15.25

Total cost= $76.25

Answer:

D. 3-5

Step-by-step explanation:

Absolute Value

[tex] |a| = a \\ | - a| = a[/tex]

Given where a-term is greater or equal to 0.

Example

[tex] |1| = 1 \\ | - 1| = 1 \\ | - 20| = 20[/tex]

Back to the question, we evaluate the absolute value of 3-5.

[tex] |3 - 5| \\ | - 2| [/tex]

Any negative real numbers in absolute will become positive real numbers.

Therefore, our answer is —

[tex]2[/tex]

Consider all choices.

[tex] |5 - 3| = |2| = 2 \\ |3 - 5| = | - 2| = 2 \\ 5 - 3 = 2 \\ 3 - 5 = - 2[/tex]

The only answer that is different is the last choice, 3-5 = -2

Answer:

The maximum height attained by the rocket is 240.1 m.

Step-by-step explanation:

The height above the ground is a function of time t is given by :

[tex]h= -4.9t^2 + 68.6t[/tex] ...(1)

We need to find the maximum height of the model. First we find the time of max height using axis of symmetry of the equation as follows :

[tex]x=\dfrac{-b}{2a}[/tex]

We have, a = -4.9 and b = 68.6

So,

[tex]t=\dfrac{-(68.6)}{2\times -4.9}\\\\=7\ s[/tex]

Put t = 7 in equation (1)

[tex]h= -4.9(7)^2 + 68.6(7)\\\\=240.1\ m[/tex]

So, the maximum height attained by the rocket is 240.1 m.

Explanation:

The piecewise function f(x) changes based on what the input is.

We have two cases:

The input x = -3 satisfies the inequality [tex]x \le 4[/tex], so we go with case B for this input

f(x) = 2x

f(-3) = 2(-3)

f(-3) = -6

In contrast, the input x = 7 satisfies the inequality x > 4. So we go for case A this time.

f(x) = 3x-1

f(7) = 3(7)-1

f(7) = 21-1

f(7) = 20

----------------------

Side note: It might be better to let g(x) = 3x-1 and h(x) = 2x. Then we could further say "If x > 4, then f(x) = g(x) OR if [tex]x \le 4[/tex], then f(x) = h(x)". Though this might be a more wordy definition.

Answer:

An equation of the line that passes through the point (6,−4) and is perpendicular to the line will be:

Step-by-step explanation:

We know that the slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept

Given the line

[tex]2x-y=5[/tex]

converting the line into slope-intercept form

y = 2x-5

comparing with the slope-intercept form of the line equation

The slope of the line = m = 2

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = 2

Thus, the equation of new line = – 1/m = -1/2 = -1/2

using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values of the slope = -1/2 and the point (6,−4)

[tex]y-\left(-4\right)=-\frac{1}{2}\left(x-6\right)[/tex]

[tex]y+4=-\frac{1}{2}\left(x-6\right)[/tex]

Subtract 4 from both sides

[tex]y+4-4=-\frac{1}{2}\left(x-6\right)-4[/tex]

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

Therefore, an equation of the line that passes through the point (6,−4) and is perpendicular to the line will be:

An equation of the line  that passes through the point (6,−4) and is perpendicular to the line 2x−y=5 is [tex]y=-\frac{1}{2}x-1[/tex]

Given:

An equation of the line that passes through the point (6,−4) and is perpendicular to the line 2x−y=5

First we find the slope of given equation 2x-y=5

y=mx+b is the equation of the line . where 'm' is the slope

[tex]2x-y=5\\2x-5=y\\y=2x-5[/tex]

Slope m=2.

Slope of perpendicular lines are negative reciprocal of one another

Slope of perpendicular line is [tex]-\frac{1}{2}[/tex]

The line passes through the point (6,-4)

Use the point and slope to get the equation of the perpendicular line

slope m = [tex]-\frac{1}{2}[/tex]

Point slope form of line is

[tex]y-y_1=m(x-x_1)\\y+4=-\frac{1}{2}(x-6)\\y+4=-\frac{1}{2}x+3\\y=-\frac{1}{2}x-1[/tex]

An equation of the line  that passes through the point (6,−4) and is perpendicular to the line 2x−y=5 is [tex]y=-\frac{1}{2}x-1[/tex]
