Answer:

go to school, do your work, you are only cheating yourself, not the school, or end up homeless

Step-by-step explanation:

The shortest distance between two points is a straight line.

Use the distance formula for points.

In the diagram, we are given two points:

(4,2) and (-3,0).

Let d = distance between the two points.

d = sqrt{(-3 -4)^2 + (0-2)^2}

d = sqrt{(-7)^2 + (-2)^2}

d = sqrt{49 + 4}

d = sqrt{53}

d = 2.2360679775

d = 2.2 miles

Answer:

A. Required probability = 11/80.

B. 3700 * 11/80 = 508.75 so the predicted number would be 509.

Answer:

6598.2 in^2

Step-by-step explanation:

Given data

Diameter= 35in

Radius= d/2= 35/2= 17.5in

Height = 60cm

The expression for the curve surface area of a cylinder is

CSA=2πrh

substitute

CSA= 2*3.142*17.5*60

CSA= 6598.2 in^2

Hence the CSA is 6598.2 in^2

I'll help you with math, is it 6th grade math?

Answer:

B

Step-by-step explanation:

4x=3y

x/y=3/4

Just like the photo I attached

If 4x=3y, then 3/4 is the ratio of x to y in the simplest form. Option B is correct.

The ratio of x to y can be determined by dividing both sides of the equation 4x = 3y by y:

4x/y = 3y/y

4x/y = 3

To express the ratio of x to y in simplest form, we divide both sides of the equation by 4:

x/y = 3 / 4

Therefore, the ratio of x to y in simplest form is 3/4. option B is correct.

Answer:

10^-5= 1/10^5

so option c is correct

Answer:

[tex]h=25[/tex]

Step-by-step explanation:

From the question we are told that:

Velocity [tex]v=40fts[/tex]

The height h function

 [tex]\large h=-16t^2+40t[/tex]

Generally time t is mathematically given by

 [tex]h'=-32t+40[/tex]

 [tex]-32t+40=0[/tex]

 [tex]t=\frac{40}{32}[/tex]

 [tex]t=1.25[/tex]

Therefore  the ball's maximum height is given as

  [tex]\large h=-16(1.25)^2+40(1.25)[/tex]

 [tex]\large h=-16(1.25)^2+40(1.25)[/tex]

 [tex]h=25[/tex]

Answer:

18.75%

Step-by-step explanation:

Given that

There is a group of 32 pupils

3 play the flute only

13 play the piano only

And, 10 play neither instrument

We need to find out the probability the student plays both instruments

So

= (32 - 13 - 10 - 3) ÷ 32

= 6 ÷ 32

= 0.1875

= 18.75%

Answer:

6/32 or 3/16

Step-by-step explanation:

13 add 10 add 3 = 26

32-26=6

the total amount of children is 32 so the number is 6/32

you can then simplify it to 3/16

Answer:

r = 24 m

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here A = 576π , then

πr² = 576π ( divide both sides by π )

r² = 576 ( take the square root of both sides )

r = [tex]\sqrt{576}[/tex] = 24

Step-by-step explanation:

110=4t+90(being vertically opposite angles)

110-90=4t

20/4=t

5=t

Answer:

Hello! answer: t = 5 degrees

Step-by-step explanation:

these are vertical angles meaning they will have the same measure! 4 × 5 = 20 and 20 + 90 = 110 therefore t = 5 HOPE THAT HELPS!

Answer:

a = 27

b = 38

c = 19

Step-by-step explanation:

a + b + c = 84

b = 2c

a = 8+c

8+c +2c+c = 84

4c + 8 = 84

4c = 76

c = 19

b = 2(19) = 38

a = 8 + 19  = 27

Answer:4

Step-by-step explanation:

x+8=2x-1

so x-9=0

and x=9

so x+6=9+6=15

and x+8=9+8=17

Answer:

27.6 is the area

Step-by-step explanation:

Area of the given triangle is equals to [tex]27.6 in^{2}[/tex](round to nearest tenth).

" Triangle is defined as two dimensional geometrical shape with three vertices, three sides and three angles enclosed in it."  

Formula used

Pythagoras theorem

(Hypotenuse)² = (Base)² + (Height)²

Area of a right triangle = [tex]\frac{1}{2} \times b\times h[/tex]

[tex]b[/tex] represents the base of the triangle

[tex]h[/tex] represents the height of the triangle

According to the question,

In a given triangle,

Hypotenuse [tex]= 11in[/tex]

Height [tex]= 6in[/tex]

Substitute the value in Pythagoras theorem to get the measure of base,

[tex](11)^{2} = b^{2} + 6^{2}\\\\\implies b^{2}= 121 -36\\\\\implies b =\sqrt{85}[/tex]

Substitute the value in the formula to find area of a triangle,

Area of a triangle [tex]= \frac{1}{2}\times \sqrt{85} \times 6[/tex]

                              [tex]= \frac{1}{2} \times 9.22 \times 6\\\\= 9.22 \times 3\\\\= 27.66[/tex]

                              ≈ [tex]27.6in^{2}[/tex] ( round to nearest tenth)

Hence,  area of the given triangle is equals to [tex]27.6 in^{2}[/tex](round to nearest tenth).

Answer: [tex]7,5.66,39^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]IJ=9\\\angle I=51^{\circ}[/tex]

from figure, we can write

[tex]\Rightarrow \sin 51^{\circ}=\dfrac{HJ}{9}\\\\\Rightarrow HJ=9\sin 51^{\circ}=6.99\approx 7[/tex]

[tex]\Rightarrow \cos 51^{\circ}=\dfrac{HI}{9}\\\Rightarrow HI=9\cos 51^{\circ}\\\Rightarrow HI=5.66[/tex]

In right angle trianle, the sum of the remaining two angles is [tex]90^{\circ}[/tex]

[tex]\therefore 51^{\circ}+\angle J=90^{\circ}\\\Rightarrow \angle J=90^{\circ}-51^{\circ}\\\Rightarrow \angle J=39^{\circ}[/tex]
