Answer:

Depends, I do that sometimes out of love and just for fun however i let them know im doing it just to mess with them. If you feel like they dont like you or you think they are a fake friend just get rid of them because later on it will break you as a person rather than make you a better person. Id suggest surrounding yourself around better peopl/frienda

Step-by-step explanation:

Line q has a slope of 5/3. Line r is parallel to line q. What is the slope if line r?

seropon [69]

Answer:

The slope remains a constant $m=\frac{5}{3}$ as it is parallel.

Explanation:

1. Line Q is defined as a slope of $\frac{5}{3}$ ; i.e. $y=\frac{5}{3}$

2. Line R is defined to be parallel of Line Q.

3. Line Q is linear and has no domain restrictions.

The definition of being parallel requires the same slope.

One of the legs of a right triangle measures 12 cm and the other leg measures 13 cm find the measure of the hypotenuse if necess

Amanda [17]

Answer:

17.7 cm

Step-by-step explanation:

One of the legs of a right triangle measures 12 cm and the other leg measures 13 cm find the measure of the hypotenuse if necessary round the nearest 10th

To find the Hypotenuse of a right angle triangle, we solve using Pythagoras Theorem

Hypotenuse ² = Opposite ² + Adjacent ²

Hypotenuse = √Opposite ² + Adjacent ²

Opposite = 12 cm

Adjacent = 13 cm

Hence,

Hypotenuse = √12² + 13²

= √144 + 169

= 17.691806013 cm

Approximately = 17.7 cm

Therefore, the measure of the Hypotenuse is 17.7 cm

What is the sum of all of the perfect squares between

Nonamiya [84]

Answer:

(-138) is the answer.

Step-by-step explanation:

Perfect square numbers between 15 and 25 inclusive are 16 and 25.

Sum of perfect square numbers 16 and 25 = 16 + 25 = 41

Sum of the remaining numbers between 15 and 25 inclusive means sum of the numbers from 17 to 24 plus 15.

Since sum of an arithmetic progression is defined by the expression

$S_{n}=\frac{n}{2}[2a+(n-1)d]$

Where n = number of terms

a = first term of the sequence

d = common difference

$S_{8}=\frac{8}{2} [2\times 17+(8-1)\times 1]$

= 4(34 + 7)

= 164

Sum of 15 + $S_{8}$ = 15 + 164 = 179

Now the difference between 41 and sum of perfect squares between 15 and 25 inclusive = $41-179$

= -138

Therefore, answer is (-138).

The cylinder is 20cm high and radius of its circular face is 3cm What is the total perimeter and area of the whole net?

trasher [3.6K]

Answer: $52\ cm,\ 176.55\ cm^2$

Step-by-step explanation:

Given

The cylinder is 20 cm high

The radius of the cylinder is $r=3\ cm$

The total area of the figure is the sum of the rectangle and two circles

$\Rightarrow \text{Perimeter P=}2[h+2r]\\\Rightarrow P=2[20+6]\\\Rightarrow P=52\ cm$

The total area of the figure is

$\Rightarrow \text{Area A=}h\times 2r+2\pi r^2\\\Rightarrow A=20\times 6+2\times \pi \times 3^2\\\Rightarrow A=120+18\pi\\\Rightarrow A=176.55\ cm^2$

What is the area of the square below?

Sedbober [7]

Answer:

O C. 5.76 in2

Step-by-step explanation:

To find the <u>area</u> of a square, the formula is

length x width = area

length = 2.4

width = 2.4

2.4in x 2.4in = 5.76 in2

in2 is the part of the answer since in x in = in2
