Answer:

2.7

Step-by-step explanation:

Since the shape is a square, just square root its area to get its side's sides.

Square root 7.29:

2^2 is 4, and 3^2 is 9, so we know that the answer is somewhere between 2 and 3

Let's try 2.5:

2.5^2 = 2.5*2.5 = 6.25, not quite

Let's try 2.6:

2.6^2 = 2.6*2.6 = 6.76, still a bit short

Let's try 2.7:

2.7^2 = 2.7*2.7 = 7.29, We have 7.29, so 2.7 is the answer!

Answer:

53.13degrees

Step-by-step explanation:

Using the SOH CAH TOA identity'

Sin theta = opposite/hypotenuse

Given

Hypotenuse AC= 10

Opposite BC = 8

Required

theta

Substitute

Sin theta = BC/AC

Sin theta = 8/10

sin theta= 0.8

theta = arcsin0,8

theta =  53.13

Hence the requred angle is 53.13degrees

Answer: [tex]1536\ m^3[/tex]

Step-by-step explanation:

Given

Box A has a volume of [tex]24\ m^3[/tex]

Box B is similar to box A such that box A dimension is multiplied by 4 to get the box B

So, each length is 4 times the box A and volume is the cube of the side.

Thus, the volume of box B is [tex]4\times 4\times 4[/tex] the volume of box A

The volume of box B is  

[tex]=4\times 4\times 4\times 24\\=1536\ m^3[/tex]

Three squares of sides 15 units, 9 units, and 12 units can form a

right-angled triangle.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

Given, We have to form a right-angled triangle that has side lengths of

3 different squares.

Let, The first square has a side length of 9 units, and let this be the height of the right-angled triangle.

Another square has a side length of 15 units and this is the hypotenuse.

Therefore, the base of the triangle must be 15² - 9² = 225 - 81 = 144 = 12 units.

So, The third square must have a side length of 12 units.

Answer:

4.9

Step-by-step explanation:

Tenths is the number directly after the "." so the 8 in 4.87 is the tenth. Rounding is quite easy, since 7 is bigger than 5 you add 1 to the 8 thus rounding the 4.87 to 4.9

Answer:

4.90

Step-by-step explanation

in 4.87 the 7 hundredth is closer to 4.90 rather than 4.80

Answer:

The distance is [tex]\sqrt{20}[/tex] or [tex]2\sqrt{5}[/tex].

Step-by-step explanation:

Slope of parallel: 2

Slope of perpendicular: -1/2

Pick a point for y =2x + 7. For example (0,7)

Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).

Distance formula [tex]\sqrt{(x_{2}-x_{1} )^{2}+(y_{2} -y_{1})^2 }[/tex]

Insert (0,7) and (4,5)

[tex]\sqrt{(0-4)^{2}+(7-5)^2 }[/tex] = [tex]\sqrt{(-4)^{2}+(2)^2 } = \sqrt{(16)+(4)} } = \sqrt{20} = 2\sqrt{5}[/tex]

The distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3 is [tex]2\sqrt{5}[/tex] and can be determined by using the point-slope form and also by using the distance formula.

Given :

First, determine the line perpendicular to the line (y = 2x + 7) whosw slope is -1/2 and intersect the line (y = 2x + 7) at point (0,7).

Using the point-slope, the equation of the perpendicular line can be determined.

[tex](y-y_1)=m(x-x_1)[/tex]    ---- (1)

where m is the slope and [tex](x_1,y_1)[/tex] is the point on the line.

Now, put the value of known terms in the equation (1).

[tex]y-7=-\dfrac{1}{2}(x-0)[/tex]

y = -0.5x + 7   --- (2)

Now, determine the point of intersection between lines (y = -0.5x + 7) and (y = 2x -3).

Substitute the value of y that is (y = 2x - 3) in equation (y = -0.5x + 7).

2x - 3 = -0.5x + 7

2.5x = 10

x = 4

Now, put the value of x in the equation (y = -0.5x + 7).

y = -0.5(4) + 7

y = 5

Now, the distance between two points is given by the equation:

[tex]\rm D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\rm D = \sqrt{(0-4)^2+(7-5)^2}[/tex]

[tex]\rm D = \sqrt{20}[/tex]

[tex]\rm D = 2\sqrt{5}[/tex]

The distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3 is [tex]2\sqrt{5}[/tex].

Answer:

The "p if and only if q" statement is equivalent to "q if and only if p", then let's rewrite all the propositions in this way.

a) "If it is hot outside you buy an ice cream cone, and if you buy an ice cream cone it is hot outside."

We can define:

q = is hot outside

p = you buy an ice cream cone

Then we can rewrite this as:

"You buy an ice cream cone if and only if is hot outside"

b)  "For you to win the contest it is necessary and sufficient that you have the only winning ticket."

We can define:

p = you winning the contest

q = have the winning ticket

Then we can rewrite (changing some words) this as:

"You will win the contest if and only if you have the winning ticke"

c) "You get promoted only if you have connections, and you have connections only if you get promoted."

We can define:

p = you get promoted

q = you have connections

We can rewrite the proposition as:

"You can get promoted if and only if you have connections"

d) " If you watch television your mind will decay, and conversely."

We can define:

p = you watch television

q = your mind will decay

We can rewrite it as:

"You can watch television if and only if your mind decays"

e) " The trains run late on exactly those days when I take it."

We can define:

p = The train runs late

q = I take it.

We can rewrite the proposition as:
