Answer: 2

You can use a calculator to compute the square root of 4 to get 2.

Or you can think of a geometric square with side lengths of some number that multiply to an area of 4. The only possible square is a 2 by 2 square since 2*2 = 4. This is where the term "square root" comes from for the most part.

Answer:65 inches

Step-by-step explanation:

15+14+36=65

Jasper used a total of 65 inches of ribbon.

To calculate the total length of ribbon used by Jasper, we need to convert the 3 feet of red ribbon to inches.

Since 1 foot is equal to 12 inches, 3 feet would be equal to 12 x 3 = 36 inches. Then, we can add up the lengths of all three ribbons: 15 inches of blue ribbon + 14 inches of yellow ribbon + 36 inches of red ribbon = 65 inches of ribbon.

Answer:

The difference is 145.7

Step-by-step explanation:

89+56.7= 145.7

Answer:

-32.3

Step-by-step explanation:

I got -32.3 because when I subtracted -89 from 56.7 I got -32.3. If you don't know how to subtract integers it's simple, you just subtract 89 from 56.7 then choose the sign that has the greater absolute value. In this case -89 has the greater absolute value, so you take the negative sign.

Final answer:

The question compares two breathing rates: 15 breaths every 36 seconds and 90 breaths every 3 minutes. When converted to breaths per minute, the rates are 25 breaths/minute and 30 breaths/minute respectively, indicating that they are not equivalent.

Explanation:

The question asks whether 15 breaths every 36 seconds and 90 breaths every 3 minutes represent an equivalent rate of breathing. To solve this, we need to determine if the two rates are the same when converted to a common time unit.

First, let's convert 36 seconds to minutes: 36 seconds is 0.6 minutes (since 1 minute is 60 seconds). Next, we calculate the breathing rate per minute for the first scenario by dividing the number of breaths by the number of minutes: 15 breaths / 0.6 minutes = 25 breaths/minute.

Now let's look at the second rate of 90 breaths every 3 minutes. This can be simplified by dividing the number of breaths by the number of minutes: 90 breaths / 3 minutes = 30 breaths/minute. Clearly, 25 breaths/minute is not equivalent to 30 breaths/minute. Therefore, 15 breaths every 36 seconds and 90 breaths every 3 minutes are not equivalent rates of breathing.

Answer:

The cost of the one word is $30 .

Option (b) i.e [tex] \frac{8.4- 6}{0.08}[/tex] is used to determine the total number of words in the ad mr.grant placed.

Step-by-step explanation:

Let us assume that the number of words in the ad be x.

As given

Mr.grant spent $8.40 to place an ad in the newspaper.

This price included one time fee of $6.00 plus $0.08 per word.

Than the equation becomes

8.40 = 6 .00 + 0.08x

Simplify the above

8.4 = 6 + 0.08x

8.4 - 6 = 0.08x

[tex]x = \frac{8.4- 6}{0.08}[/tex]

[tex]x = \frac{2.4}{0.08}[/tex]

[tex]x = \frac{24\times 100}{8\times 10}[/tex]

[tex]x = \frac{2400}{80}[/tex]

x = $30

Therefore the cost of the one word is $30 .

Option (b) i.e [tex] \frac{8.4- 6}{0.08}[/tex] is used to determine the total number of words in the ad mr.grant placed.

Answer:

Yes, one of a rhombus's properties is that the diagonals bisect vertex angles.

The diagonals of a rhombus bisect the vertex angles.

Yes, the diagonals of a rhombus bisect the vertex angles.

To understand this, we can consider that in a rhombus, the diagonals are perpendicular to each other, and when a diagonal bisects an angle, it creates two congruent triangles.

Therefore, the diagonals of a rhombus do indeed bisect the vertex angles.

Answer:

v2 - v02 = 2ad

v = final speed = 0 (came to a full stop)

v0 = initial speed (what you want to solve for)

d = stopping distance = 175 feet

Then

v0 = √(-2ad)  [Remember a is negative, so the argument of the square root is positive.]

But as you can see, we need the acceleration.

If we knew the time it took to come to a full stop, we could still answer the question.  Either way, we need more information than just the stopping distance.

Step-by-step explanation:

The speed of the vehicle before the brake were applied was about 83.7 feet/s

Acceleration is rate of change of velocity.

[tex]\large {\boxed {v^2 = u^2 + 2ad}[/tex]

[tex]\large {\boxed {a = \frac{v - u}{t} } }[/tex]

[tex]\large {\boxed {d = \frac{v + u}{2}~t } }[/tex]

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem!

This problem is about accelerated motion.

Given:

final speed of the vehicle = v = 0 feet/s

length of skid marks = d = 175 feet

maximum deceleration = a = 20 feet/s² ( assumption )

Unknown:

initial speed = u = ?

Solution:

[tex]v^2 = u^2 - 2ad[/tex]

[tex]0^2 = u^2 - 2(20)(175)[/tex]

[tex]u^2 = 7000[/tex]

[tex]u = \sqrt{7000}[/tex]

[tex]u = 10\sqrt{70} \texttt{ feet/s}[/tex]

[tex]u \approx 83.7 \texttt{ feet/s} [/tex] (rounded to the nearest tenth)

[tex]\texttt{ }[/tex]

The speed of the vehicle before the brake were applied was about 83.7 feet/s if we assume that maximum deceleration of the vehicle is about 20 feet/s²

Answer:

A and C represent a function and B doesn't represent.

Step-by-step explanation:

A function is a relation that maps one output value of y for each input value of x.

A. Ordered pairs can be written as relation

Here each input value of x determines one output value of y and this set of ordered pairs represents function.

B. Ordered pairs can be written as relation

Here for input value x=9 there are 2 output values of y (y=3 or y=-3). This set of ordered pairs doesn't represent function.

C. Ordered pairs can be written as relation

There is exactly one y for each x, then this set of ordered pairs represents function.

Answer:

Step-by-step explanation:

The installation cost is $300 and the cost per square foot is $4 . So the total price is y= 4x + 300 (where x is square foot).

slope is 4 and y intercept is 300

for 375 sqft. the cost is y= 4(375) +300 = 1800

the cost is $1800

Answer:

1/32

Step-by-step explanation:

1/8 divided by 4 = .03125

.03125= 1/32

Any irrational number never ends. So, you can take square roots. 4 is the square root of 16, and 6 is the square root of 36. So, take the square root of any number between 16 and 36 except for 25. For example, 17 is between 16 and 36. So, sqrt(17) is therefore irrational. You can't take the square root of 25 because that would result in a rational number, 5.

Step-by-step explanation:

The given expression is

[tex](-3+3i)+(-2+3i)[/tex]

It can be written as

[tex]-3+3i-2+3i[/tex]

Now combine like terms.

[tex](-3-2)+(3i+3i)[/tex]

[tex](-3-2)+(3+3)i[/tex]

Simplify each parenthesis.

[tex](-5)+(6i)[/tex]

[tex]-5+6i[/tex]

Therefore the value is  of given expression is -5+6i.

Answer:

Number of marbles are 200000

Step-by-step explanation:

Rectangular box:

length = 5 feet

width =4 feet

height =3 feet

now, we can find volume of box

[tex]V=L\times W\times H[/tex]

[tex]V=5\times 4\times 3[/tex]

[tex]V=60ft^3[/tex]

Volume of marbles:

We know that shape of marbles will be in sphere

we are given

diameter =1 inch

radius =0.5 inch

[tex]r=\frac{0.5}{12} ft[/tex]

now, we can find volume

[tex]V=\frac{4}{3}\pi r^3[/tex]

we can plug value

[tex]V=\frac{4}{3}\pi (\frac{0.5}{12})^3[/tex]

[tex]V=0.00030[/tex]

now, we can find number of marbles

Number of marbles = ( volume of box)/( volume of marbles)

So, number of marbles are

[tex]=\frac{60}{0.00030}[/tex]

[tex]=200000[/tex]

Step-by-step explanation:

23,453 is not a perfect square, this is because no rational number times itself equals 23,453, which can be proven if you go into a calculator and find the square root of 23,453, which is about 153.1437 (but it continues going, making it an irrational number.)
