I really need the help with this

Answer:

63

Step-by-step explanation:

Answer:

the area is 43cm²

Step-by-step explanation:

First, you find the area of the left side. 7cm - 3cm= 4cm

Secondly, you multiply 4cm x 4cm = 16cm

Then, you find the area of the bottom bit. 9cm x 3 cm = 27cm

Lastly, you add 27cm + 16cm, which brings your answer to...

43cm² :-)

(It's squared because you are finding the area)

Answer:

[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]

They lie on the same horizontal line

Distance = 11 units

[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]

They do not lie on the same vertical or horizontal line

Step-by-step explanation:

Given

[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]

[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]

Required

Determine if the points lie on the same vertical or horizontal line

A point is represented as: [tex](x,y)\\[/tex]

Using the above illustration, we have:

[tex](a)\ (0, -2)\ and\ (0, 9)[/tex]

The above have the same x values (0), hence they lie on the same horizontal line.

The distance between them is:

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

[tex]d = \sqrt{(0-0)^2 + (-2 - 9)^2}[/tex]

[tex]d = \sqrt{0^2 + (-11)^2}[/tex]

[tex]d = \sqrt{0 + 121}[/tex]

[tex]d = \sqrt{121}[/tex]

[tex]d = 11[/tex]

The distance between them is 11 units

[tex](b)\ (11, 4)\ and\ (2, 11)[/tex]

The above pair do not have the same x value and they do not have the same y value.

Hence, they do not lie on the same vertical or horizontal line

Answer:

18.2

Step-by-step explanation:

32.5÷2.72=11.9

32.5-11.9=20.6

20.6-2.4m=18.2

Answer:

The range of this set of numbers is 9

Step-by-step explanation:

The range is the greatest number subtracted by the lowest number

in this problem that is 21-12

Answer:

9

Step-by-step explanation:

range = highest number in a set minus the lowest number in a set, in your case:

21 - 12 = 9

Answer:

28.27 I believe

Step-by-step explanation:

Answer:

28.26ft²

Step-by-step explanation:

A = πr²

plug in 3 for r

A = π(3²)

A = π(9)

A = 3.14(9)

A = 28.26ft²

Answer:

from what we're given on the drawing, ac and pt are congruent

and from the question format, ab is equal to pq, ac is equal to pr

Answer: the exact volume is 1,357.168

Step-by-step explanation:

Answer:

1356.48 cm³

Step-by-step explanation:

V = πr²h

V = 3.14 × (6 cm)² × 12 cm

V = 1356.48 cm³

Answer:

Hello! Just did the assignment! Your answer would be d. x-axis! Hope you stay safe! :)

Answer:

324ft^2

Step-by-step explanation:

rectangle: 22ft X 12ft = 264ft^2

trapazoid: 1/2(22+8)4 = 60ft^2

264 + 60 = 324ft^2

hope this helped!! :D

tell me if you need further explaination!

Answer:

We add for example when they give us something and words we already had keys we subtract when it exists as "we should"

Answer:

Y = 60 degrees and X = 12

Step-by-step explanation:

x+3 and 15 are congruent so x+3 = 15, 12+3 = 15 therefore x = 12

y = 60 vertically opposite angles are equal. :D

Answer:

x= 12

y= 60

Step-by-step explanation:

to find x we need to know that lines DC and AB are parallel, so they have the same length (I don't know if that is why they have the same length, but I know they do lol)

So you can make this equation and solve:

15=x+3

-3     -3

12=x

THEN, to find y angle A and C are vertical angles, so they are congruent (this is the reason why they have the same measure lol)

So, y=60 degrees :)

I hope this sorta helps lol :)

Answer:

after 11.07secs

Step-by-step explanation:

Given the height of an object modeled by the equation

H = 16T² - 1960

The height of the object on the surface of water is zero, hence H = 0

Substitute

0 =16T² - 1960

Swap

16T² - 1960 = 0

16T² = 1960

T² = 1960/16

T² = 122.5

T = 11.07

Hence the rock will hit the surface of the water after 11.07secs

Answer:

In this question you got multipel answers.

If she buys as much pants as she can;

135 - (15.p) = 5.s

135 - (15.9) = 0

so now she has bought no shirts and 9 pants.

if she buys as much shirts as she can;

135 - (5.s) = 15.p

135 - (5.27) = 0

so now she has bought no pants and 27 shirts.

If she wants a shirt for each pants the equation would look something like this;

p=s=x

135 - (15.x) = 5.x

but with each pants she can buy three shirts, so 9 = 3.3

(7.15)+(6.5)= 105+30= 135

so now she has 7 pants and 6 shirts.

Answer:

7.81 u

Step-by-step explanation:

Given :-

And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,

[tex]:\implies[/tex] D = √{(x2-x1)² + (y2-y1)²}

[tex]:\implies[/tex] D =√[ (3+2)² +(-3-3)²]

[tex]:\implies[/tex] D =√[ 5² +6²]

[tex]:\implies[/tex] D =√[ 25 +36]

[tex]:\implies[/tex] D = 61

[tex]:\implies[/tex] D = 7.81

Answer:

20

Step-by-step explanation:

Hope this helps!!!!

If it is tens its 20

If it ins tenth its 19.8

To round 19.798 to the nearest tenth consider the hundredths’ value of 19.798, which is 9 and equal or more than 5. Therefore, the tenths value of 19.798 increases by 1 to 8.

19.798 rounded to the nearest tenth = 19.8

Answer:

19.8

Step-by-step explanation:

I'm not sure if you mean "tens" or "tenths" so I assumed "tenths".

If it was "tens" then it would be 20.
