3 3/5 x (-8 1/3) = ?

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:

slope of AB = 0

Step-by-step explanation:

The slope of the x- axis OX = 0

Since AB is parallel to the x- axis and parallel lines have equal slopes, then

slope of AB = 0

Since, the line AB is parallel to X - axes, so every point on the the line AB will have equal Y - coordinates.

lets take it as Y ( y - coordinate is same )

slope :

=》

[tex] \dfrac{y2 - y1}{x2 - x1} [/tex]

but since y2 and y1 are equal, so

[tex] \dfrac{ Y - Y }{x2 - x1} [/tex]

=》

[tex] \dfrac{0}{x2 - x1} [/tex]

=》

[tex]0[/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

hope this helps :)

Answer: -5/12

Step-by-step explanation:

Data: 3/12-1/6-1/4-1/4=x

Step one, Find the common demoninator of the fractions

3/12-1/6-1/4-1/4 = 3/12-2/12-3/12-3/12

Reason: You can't subtract fractions that don't have the same denominatory so by finding the common demoninator you allow the problem to be solved.

Step two, Subtract

3/12-2/12= 1/12-3/12=-2/12-3/12=-5/12

Reason: You subtract fractions(With the same denominator) like normal numbers but you keep the denominator the same. When subtracted, the end result is -5/12 since subtracting a bigger number from a smaller number creates a negative.

Answer: -5/12

I hope this helps!

Answer:

The questions that are appropriate for the teacher to ask her population are:

How many hours of sleep do you get per night?

On average, how long does it take you to complete your homework?

What time do you leave for school in the morning?

Step-by-step explanation:

The survey is conducted among the seventh grade students so the valid question their teacher would have asked them is:

How many hours of sleep do you get per night?

On average, how long does it take you to complete your homework?

What time do you leave for school in the morning?

while the other two questions are invalid as it the students are young and they are not legal to vote.

also it is not necessary that they would arrive to school by car. Please mark the brainliest!

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

You can do Pythagoras' theorem:

17^2-15^2=64

so [tex]\sqrt{64}[/tex]=4

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: [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]

Answer:

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:

10 is the hypotenuse

Step-by-step explanation:

a² + b² = c²

Given:

a = 8

b = 6

Work:

a² + b² = c²

8² + 6² = c²

64 + 36 = c²

100 = c²

[tex]\sqrt{c^2} =\sqrt{100}[/tex]

c = 10
