Answer:
acute angles
Step-by-step explanation:
A right angle measures 90 degrees, so if you split it into 2 parts, each part will measure less than 90 degrees. Thus, the two angles will be <u>acute</u>
oh i just watched a vid for that lol. That question was on it.. here <3

Step-by-step explanation:
it is a rectangle (usually).
so,
2×length + 2×width = 80
therefore, length + width = 40
length×width = 384
length = 384/width
384/width + width = 40
384 + width² = 40×width
width² - 40×width + 384 = 0
the general solution for such a square equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = width
a = 1
b = -40
c = 384
width = (40 ± sqrt((-40)² - 4×1×384))/(2×1) =
= (40 ± sqrt(1600 - 1536))/2 =
= (40 ± sqrt(64))/2 = (40 ± 8)/2 =
= 20 ± 4
width1 = 20 + 4 = 24 cm
length1 = 40 - 24 = 16 cm
width2 = 20 - 4 = 16 cm
length2 = 40 - 16 = 24 cm
so, both solutions are the same.
the greeting card is 24×16 cm. or 16×24, depending on how you are holding it.

Answer:
Evan purchased 7 frozen dinners and 9 cans of soup.
Step-by-step explanation:
Since Evan went to the grocery store and purchased cans of soup and frozen dinners, and each can of soup has 150 mg of sodium and each frozen dinner has 550 mg of sodium, and Evan purchased a total of 16 cans of soup and frozen dinners which collectively contain 5200 mg of sodium, to determine the number of cans of soup purchased and the number of frozen dinners purchased the following calculation must be performed:
16 x 550 + 0 x 150 = 8800
8800 - 5200 = 3600
550 - 150 = 400
3600/400 = 9
7 x 550 + 9 x 150 = X
5200 = X
Therefore, Evan purchased 7 frozen dinners and 9 cans of soup.
