School is Cool. The ORH ASB wants to determine if their efforts at increasing school spirit have been
successful. Kenny, Katrina and Sally conduct a survey where they take an SRS of 250 students at the
school and ask them if they have more school spirit now than at the beginning of the school year. Of the
250 surveyed, 91 of them said they did. Does this provide strong evidence that more than a third of the
students are more spirited now than they were at the beginning of the year?

The sum of the squares of the two smaller sides is equal to the square of the third side.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right angle triangle, equilateral triangle, and much more.

Given,

Δabc is a right-angle triangle

By Pythagoras theorem

Hyp² = perp² + base²

Here

Hyp = c (longer side)

Pepe and base = a and b

So,

c² = a² + b²

(Longer side)² = a² + b²

Hence, The sum of the squares of the two smaller sides is equal to the square of the third side.

The sum of the squares of the two smaller sides is equal to the squares of the third side.

Option B is the correct answer.

Given,

The triangle above is a right triangle with side lengths a = 7 in, b = 24 in, and c = 25 in.

We need to see which option is true.

It states that in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

The triangle above is a right triangle with side lengths:

a = 7 in

b = 24 in

c = 25 in

Here c = hypotenuse.

So applying the Pythagorean theorem.

c^2 = a^2 + b^2

25^2 = 7^2 + 24^2

625 = 49 + 576

625 = 625

We see that the given values satisfy the Pythagorean theorem.

Thus the sum of the squares of the two smaller sides is equal to the squares of the third side.

Option B is the correct answer.

Answer:

A school ordered 300 bulbs that cost $1 and 150 bulbs that cost $2.

Step-by-step explanation:

Let [tex]u[/tex] denotes number of light bulbs that cost $1 and [tex]v[/tex] denotes number of light bulbs that cost $2.

Twice as many $1 bulbs as $2 bulbs were ordered.

[tex]u=2v[/tex]

A school ordered $600 worth of light bulbs.

[tex]u(1)+v(2)=600\\u+2v=600[/tex]

Put [tex]u=2v[/tex] in [tex]u+2v=600[/tex]

[tex]2v+2v=600\\4v=600\\\\v=\frac{600}{4}\\\\v=150[/tex]

Put [tex]v=150[/tex] in [tex]u=2v[/tex]

[tex]u=2(150)=300[/tex]

Therefore,

A school ordered 300 bulbs that cost $1 and 150 bulbs that cost $2.

honestly i was a little confused with the way this question was worded so please tell me if i did something wrong or if i didn't explain/understand this right!

answer:

3 dollars or 300 cents

step-by-step explanation:

well we know that 4 quarters equal one whole dollar so what i did was divide 12 by 4 to get 3 whole dollars

12/4

= 3 dollars

and we know that 100 pennies equal one whole dollars, all you need to do was multiply 3 dollars by 100 pennies

3 * 100

= 300 pennies

Answer:

to differential calculus, because I don't know how to answer this question without

using it.

We're told that Jason's height above the water is  H(t) = -16t² + 16t + 480 .

We can observe many things from this equation:

-- Up is the positive direction; down is the negative direction.

-- The acceleration of gravity is 32 ft/sec² .

-- Jason jumps upward from the cliff, at 16 ft/sec .

-- The cliff is 480-ft above the water.

(This tells us why the question is only concerned with his maximum height,

and then it ends ... 480-ft is one serious cliff, and what happens after the

peak of his arc is too gruesome to contemplate.)

In any case, his vertical velocity is the first derivative, with respect to time,

of his height above the water.

        V = -32 t + 16

At the peak of his arc, where gravity takes over, his velocity changes from

upward to downward, and it's momentarily zero.

                                          0 = -32t + 16

Add  32t  to each side:    32t = 16

Divide each side by  32:      t = 1/2 second

His height at that instant is     H(0.5) = -16(0.5)² + 16(0.5) + 480 =

                                          4-ft above the cliff,  484-ft above the water,

and then he begins falling from that altitude.

The duration of his dive is      484 = 16 t²

                                                  t = √(484/16) = 5.5 seconds

and he hits the water at      V = a t = (32) x (5.5) = 176 ft/sec = exactly 120 mph

Answer:

Step-by-step explanation:

L= length

w= width= L-3

A= area= 238 ft^2

LENGTH

Area Formula

A= LW

substitute w value

238= (L)(L- 3)

multiply L by parentheses

238= L^2 - 3L

subtract 238 from both sides

0= L^2 - 3L - 238

factor

0= (L + 14)(L - 17)

set each parentheses equal to 0

0= L + 14

-14= L

OR

0= L - 17

17 ft= L

*Since the measure of a rectangle would not be negative, L= 17 ft

WIDTH

w= L - 3

w= 17 - 3

w= 14 ft

ANSWER: Length= 17 ft; Width= 14 ft

Answer:

Length= 17 ft; Width= 14 ft

Step-by-step explanation:

L= length

w= width= L-3

A= area= 238 ft^2

LENGTH

Area Formula

A= LW

substitute w value

238= (L)(L- 3)

multiply L by parentheses

238= L^2 - 3L

subtract 238 from both sides

0= L^2 - 3L - 238

factor

0= (L + 14)(L - 17)

set each parentheses equal to 0

0= L + 14

-14= L

OR

0= L - 17

17 ft= L

*Since the measure of a rectangle would not be negative, L= 17 ft

WIDTH

w= L - 3

w= 17 - 3

w= 14 ft

ANSWER: Length= 17 ft; Width= 14 ft
