Answer:
3.2
Step-by-step explanation:
12 4/5 times 1/4= 3 1/5 or 3.2
Answer:
see below
Step-by-step explanation:
19. -9 x = -117
20. -¹/₈ x = -³/₄
21. ⁵/₆ x = -⁵/₉
---------------------
19.
x = 117 / 9
x = 13
20.
x = ³/₄ divide ¹/₈
x = 6
21.
x = -⁵/₉ divide ⁵/₆
x = -²/₃
Answer:
a° = 58°
b° = 48°
c = 74°
d° = 122°
Step-by-step explanation:
<em>Angles on a straight line add up to 180°</em>
58° + d° = 180°
d° = 180° - 58° = 122°
<em>Alternate angles are equal.</em>
a° = 58°
<em>Angles in a triangle add up to 180°.</em>
48° + 58° + c° = 180°
106° + c° = 180°
c° = 180° - 106° = 74°
<em>Angles on a straight line add up to 180°</em>
74° + 58° + b° = 180°
132° + b° = 180°
b° = 180° - 132° = 48°
If a 4000 watt oven is on for 5 hours, then how many kilowatt-hours (kw-hrs) of energy are used?
Solution: We are given that the oven is 4000 watt and it is on for 5 hours.
We have to find the how many kilowatt-hours (Kw-hrs) of energy are used by the oven.
We first need to convert watts into kilowatt's. We know that:
Therefore, 4000 Watts
Now, we can find how many kilowatt-hours (Kw-hrs) of energy are used by the oven.
Energy used by the oven Kw-hrs
Therefore, 20 kilowatt-hours (kw-hrs) of energy are used by the oven.
Answer:
SAS means "Side, Angle, Side"
ASA means "Angle , Side, Angle"
AAS means "Angle, Angle, Side"
HL stangs for "Hypotenuse, Length"
Step-by-step explanation:
SAS is when we have two sides meeting and forming an angle between them.
ASA is when we know two angles and a side between the angles.
AAS is when we know two angles and a side which is not between the angles.
HL means that: two triangles are congruent if the hypotenuse of one triangle is equal to the hypotenuse of the other and if one leg of a triangle is equal to a leg of another triangle.
