Answer:

300 students

Step-by-step explanation:

Since 4/5 of students do not wear glasses, 1/5 of students do.  

There are 60 students who wear glasses, so let 'x' represent the number of students who wear glasses

(1/5)x = 60     is our equation.  "One-fifth of the number of students who wear glasses is 60"

Now solve for x

(1/5)x = 60

    x = 300    (multiply both sides by 5 to get rid of the fraction)

In the function y= -1/2(x-1)^2+3, the negative sign inverts the graph so that it opens downwards unlike y=x^2 that opens upwards. This is due to the negative slope which implies a descent in the graph when moving left to right, showing a negative correlation between x and y.

In the function y= -1/2(x-1)^2+3, the negative sign in front of the fraction plays a vital role in the graph's orientation. Unlike the graph of y=x^2 which opens upwards, the negative sign causes the graph of the given function to open downwards. This occurs because the negative sign affects the slope of the function. Graphically, a negative slope means that as we move from left to right along the graph, it descends; showing a negative correlation between x and y. Thus in the concoction of a graph, when x increases, y decreases, or when x decreases, y increases. This is a fundamental rule in graphing quadratic functions.

The negative sign in the function [tex]y = -1/2(x-1)^2+3[/tex]inverts the graph compared to[tex]y = x^2[/tex], making the parabola open downwards and indicating a negative relationship between the x and y values.

The negative sign in the function [tex]y = -1/2(x-1)^2+3[/tex] in comparison to the function [tex]y = x^2[/tex]inverts the graph of the parabola. While the graph of[tex]y = x^2[/tex]opens upwards, the negative coefficient causes the graph of the given function to open downwards. This means that instead of the parabola having a minimum point which occurs in [tex]y = x^2[/tex], the parabola will have a maximum point at the vertex (1, 3). As the x-value increases or decreases from the vertex, the y-value will decrease due to the negative sign, indicating that the two variables are negatively related. The general shape of the graph remains a parabola, but it is flipped vertically over the x-axis.

Answer:

"multiply the previous value by 3"

Step-by-step explanation:

We can easily see the pattern if we look at the 2nd, 3rd, 4th terms.

Now, we can see 1st and 2nd terms (which wasn't that apparent for some). Does multiplying 1/3 by 3 give us 1? INDEED, it does!

So the rule is "multiplying the previous term by 3".

The height of the tree is 23 meters

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Let  the height of the tree as 'x'.

The proportion can be set up as:

(height of the tree) / (length of the tree's shadow) = (height of the building) / (length of the building's shadow)

Plugging in the given values:

x / 9 = 54 / 21

To solve for x, we can cross-multiply:

21x = 54×9

21x = 486

Dividing both sides by 21:

x = 486 / 21

= 23.143

Hence,  the height of the tree is 23 meters.

Answer:

the first one is (cylinder) and second one is (6 units)

The radius of base is, 5 units

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Since, it has a perimeter of 32 units and it is to be rotated about the line, the solid to be created it is a cylinder. As you can see below.

Hence, Let's calculate its radius, based on the information given, i.e. the perimeter as,

2p = 32

Since, We know that;

2p = b + b + h + h

2p = 2 (b + h)

2 (b + h) = 32

b + h = 16

And, bh = 60

This gives solutions,

b = 10 and h = 6

Since, the line of rotation is the center, and the radius is half the line segment of the basis,

➷ 1) You have to find the equation of the line first:

y = mx + c

First find the slope

slope = difference in y / difference in x

slope = 6/3

slope = 2

Answer:

-1

Step-by-step explanation:

To find the slope of a line, you would need to use the slope formula, and that is [tex]slope=\frac{y2-y1 }{x2-x1}[/tex]

This equation should be used every time you need to find a slope with two given points. If you remember this, you would find questions like this more easy.

First, you would need to plug in your coordinate points into the formula.

You would plug -7 in y2, 2 in y1. And then you will plug in 4 in x2, and -5 in x1.

Your equation should look like this:

[tex]\frac{-7-2}{4-(-5)}[/tex]

Then you solve.

For the top portion of your equation you would get -9. The -5 turns into a positive 5 because when you carry the negative over (distribute it), the negative cancels out and turns into a positive. When you add the 5 and the 4 together, it will get you 9. The bottom portion of the equation will be 9.

Your equation should now look like this:

[tex]\frac{-9}{9}[/tex]

Now, you divide.

When you divide, the two 9's end up as a whole, and you keep the negative since the negative doesn't cancel out in this situation. When you finish dividing, you would get -1.

Your FINAL answer would be -1.

Answer:

-1

Step-by-step explanation:

    Slope formula:

             ↓

 [tex]{\huge\frac{Y_2-Y_1}{X_2-X_1}[/tex]

[tex]\frac{(-7)-2}{4-(-5)}=\frac{-9}{9}=-1[/tex]

Therefore the slope is -1.

-1 is the correct answer.

Alex had 193 cards. Meg had 120 more, Gil 20 more than Alex, for a total of 740 shared.

Let x be the number of cards Gil had.

Alex had x - 20 cards.

Meg had x + 120 cards.

The total number of cards is x + (x - 20) + (x + 120) = 740.

Combining like terms, we get 3x + 100 = 740.

Subtracting 100 from both sides, we get 3x = 640.

Dividing both sides by 3, we get x = 213.33.

Since the number of cards must be a whole number, we can round 213.33 down to 213.

Therefore, Alex had 213 - 20 = 193 cards.

So the answer is 193

Answer:

At = 21.5 cm2

Step-by-step explanation:

At = Asqr - Acircle

At = A1 - A2

A1 = 10^2  = 100

A2 = Pi*(5)^2 = 78.5

At = 100 - 78.5

At = 21.5 cm2

Best regards

For this case we have that by definition:

The area of a circle is: [tex]A_ {c} = \pi * r ^ 2[/tex]

Where r is the radius of the circle.

The area of a square is: [tex]A_ {s} = l ^ 2[/tex]

Where l is the side of the square.

The area of the shaded region will be:

[tex]A_ {sr} = A {s} -A_ {c}[/tex]

So:

[tex]A_ {s} = 10 * 10\\A_ {s} = 100 \ cm ^ 2[/tex]

On the other hand:

[tex]A_ {c} = \pi * (\frac {10} {2}) ^ 2\\A_ {c} = \pi * 25\\A_ {c} = 78.5375cm ^ 2[/tex]

Finally:

[tex]A_ {sr} = 100-78.5375\\A_ {sr} = 21.4625[/tex]

Rounding out, we have that the area of the shaded region is 21.5 square centimeters.

total distance of 24 laps

29.6km - 0.2km

=29.4km

total distance of each lap

24 laps = 29.4km

1 lap = ?

Use cross-multiple

24 laps × X = 29.4km × 1 lap

X = 29.4km / 24

X = 1.225km

Answer

1.225km

Answer:

1.225km is equal to each laps

Step-by-step explanation:

Since Kristy total distance traveled = 29.6km

And Kristy ran 24 laps and later walk 0.2km. it simply implies that

Total distance traveled = distance covered running + distance covered walking

Since we know that

Total distance traveled = 29.6km

distance covered running = 24 laps

distance covered walking = 0.2km

Distance covered running in km = total distance traveled - distance covered walking

Distance covered running in km = 29.6km - 0.2km = 29.4km.

To now find the distance for each lap.

Since we have:

Distance covered running in km = 29.4km.

Distance covered running in lap = 24 laps

i.e

24 laps = 29.4km

1 lap = x

Use cross-multiple

24 laps * x = 29.4km × 1 lap

x = 29.4km / 24

x = 1.225km

Therefore

1.225km is equal to each laps.

To express 5 √ 4 using rational exponents, you write it as 5¹ × 4¹⁄₂, as the square root of a number is that number raised to the power of ½.

To write 5 √ 4 using rational exponents, we must express the square root of 4 as a power. From our mathematical rules, we know that a square root can be written as an exponent of ½. Therefore, √4 is equivalent to 4 to the ½ power (4¹⁄₂).

Considering the expression 5 √ 4, we apply the same concept. The 5 is actually 5 to the power of 1 (5¹), and the square root of 4 is 4 to the ½ power. When these are multiplied together, we combine the base of 5 with the exponent expressions, remembering that the 4¹⁄₂ needs to be multiplied by 5¹. Consequently, 5 √ 4 becomes 5¹ × 4¹⁄₂.

The expression 5√4 can be written using rational exponents as 5 * [tex]4^{1/2}[/tex].

To express the given expression 5√4 using rational exponents, we start by understanding what the square root represents in exponential form. The square root of a number x can be written as [tex]x^{1/2}[/tex]. For our given expression, we need to follow these steps:
