Answer:

142 degrees

Step-by-step explanation:

The sum of angle in a quadrilateral is 360 degrees

33 + 20 + 165 + X =360

53 + 165 + X = 360

218 + X = 360

X = 360 - 218

X = 142

Hence the size of angle X is 142 degrees

What is the slope of the line that passes through (4,26) and (-45,22.)

dusya [7]

It is 1/11 or 4/44.

Explained:

This is because when you subtract 26 and 22 you get 4 and when you subtract 4 and -45. The 45 then becomes a positive since when you get a negative and a negative you get a positive. Then you simplify it by 11.

Which one is larger and why 12 x 3/7 or 6 x 3/7

Serggg [28]

Answer:12 x 3/7 is larger than 6 x 3/7.

12x3/7=36/7 while 6x3/7=18/7 since both fractions 36/7 and 18/7 have the same denominators, to know which is larger we just check the numerator,the fraction with the largest numerator is largest which is 36/7

Step-by-step explanation:

12x3/7=(12x3)/7=36/7

6x3/7=(6x3)/7=18/7

36/7 is larger than 18/7

Shaquil needs to borrow $400. The loan company charges him $80 in fees for the loan. Shaquil calculates that the annual percenta

lesya [120]

Answer:

(B)

Step-by-step explanation:

PRINCIPAL AMOUNT(p) = $400

RATE (r)= 250% = 2.5

INTEREST = $80

t = time (in days) = t/365

By using the formula,

r = $\frac{i}{pt}$

2.5 = $\frac{80*365}{400*t}$

t = $\frac{364*80}{400*2.5}$

t = 29.2

t = 29 days (approx)

Hence option (B) is correct.

madeline studies honeybees. every week she weighs the same honeybee hive, the first week the hive weighs 11.607 kilograms. its w

fomenos

So, we already know that one hive has a weight of 11.607kg and .204kg is add each week, so we add on .204kg times, w, representing weeks onto 11.607kg and our t is our total of weight of a hive with respect to weeks

$w = weeks \\ t = total \: weight \: with \: respect \: to \: weeks$
So in this case our w is 7.5 weeks and now we evaluate t

$w = 7.5 \: weeks \\ t = ?$
Solve
$11.607kg + .204kg(w) = t \\ 11.607kg + .204kg(7.5) = t \\ t = 13.137kg$
Answer:

Hive's weight will increase by 1.53kg in 7.5 weeks to 13.137kg
