Mathematics

NeX [460]3 years ago

5 0

Answer:

120

Step-by-step explanation:

The sum of the degrees in any quadrilateral is 360. So add up all of the degrees you know and subtract it from 360 to get your answer.

120 + 60 + 60 = 240

360 - 240 = 120

another way you know that's easier is the angles that are diagonal are equal to one another, so since x is diagonal to 120, it is equal to 120.

Find the circumference of the circle and round to the nearest tenth

VLD [36.1K]

Answer:

The circumference is 45.2yd

Step-by-step explanation:

Given

$d = 14.4$ --- diameter

Required

Determine the circumference

The circumference is calculated as:

$C =\pi d$

So, we have:

$C =\pi * 14.4$

Take pi a 3.14

$C =3.14 * 14.4$

$C =45.216$

Approximate

$C =45.2yd$

On a word processing test, Iko typed 694 words in 15 minutes. On that same test six days later, Iko typed 753 words in 15 minute

Answer:

The improve in speed is 3.9334 words/min

Step-by-step explanation:

we will find speed at both occasions and then we can subtract them

First test:

total number of word =694

total time =15 min

we know that

speed = (total number of words)/( total time)

now, we can plug values

speed is

$=\frac{694}{15}$ word/min

$s_1=46.2666$ word/min

Second test:

total number of word =753

total time =15 min

we know that

speed = (total number of words)/( total time)

now, we can plug values

speed is

$=\frac{753}{15}$ word/min

$s_2=50.2$ word/min

So, improve in speed is

$=s_2-s_1$

$=50.2-46.2666$

$=3.9334$ word/min

If an object is shot with an initial velocity of 160 ft/sec, what is the smallest initial angle will you need to obtain a horizo

MrRissso [65]

To solve the question we shall use the formula for the range given by:
Horizontal range, R=[v²sin 2θ]/g
plugging in our values we get:
500=[160²×sin 2θ]/10
5000=160²×sin 2θ
0.1953=sin 2θ
thus:
arcsin 0.1953=2θ
11.263=2θ
hence:
θ=5.6315°~5.63
