What is the length of BC in the right triangle below?
Answer:
Option A
Step-by-step explanation:
Use the Pythagoras Theorem
Hypotaneous² = base² + height²
BC² = AB² + AC²
BC = √ (AB² + AC²)
BC = √ (12² + 16²)
BC = 20
Answer:
20
Step-by-step explanation:
Here's your solution
=> in a right angle traingle
BC^2 = AB^2 + AC^2
=> BC^2 = 16^2 + 12^2
=> BC ^2 = 256 + 144
=> BC^2 = 400
=> BC = √400
=> BC = 20

Que volumen ocupan 0.8kg de alcohol?¿cual es el peso de este volumen? la densidad del alcohol es 790 kg/m3
Respuesta:
Volumen = 0.0010126 m³
Ancho = 7,84 N
Explicación paso a paso:
Dado que:
Masa, m de alcohol = 0,8 kg
Densidad del alcohol, d = 790 kg / m³
Recordar :
Densidad, d = masa, m / volumen, v
Volumen = masa / densidad
Volumen = 0,8 kg / 790 kg / m³
Volumen = 0.0010126 m³
Peso, W = densidad * aceleración debido a la gravedad * volumen
Ancho = 790 * 9,8 * 0,0010126
W = 7.8395
Ancho = 7,84 N

Answer:
g. 9−7+{−2+3−[4−2+(3+2)−7]+8} = 11
h. – {- [ (14 - 7) - (32 - 41)]} = + 16
i. – [(-8 + 3) + (- 21 – 12)] = + 38
j. 500 – {( 6 – 18 + 4 + 3 + 16 - 10 – 2) – 5 } = 506
k. (9 + 7 – 2 + 4) – ( 9 -12 ) =21
Step-by-step explanation:
These questions are solved by solving the small brackets, then square brackets and then the curly brackets.
g. 9−7+{−2+3−[4−2+(3+2)−7]+8}
= 9−7+{−2+3−[4−2+(5)−7]+8} Solving inner small brackets
= 9−7+{−2+3−[9−2−7]+8} Solving outer square brackets
= 9−7+{−2+3−0 +8} Solving curly brackets
=9−7+{9} Adding like terms ( adding positive terms)
= 18-7
= 11
h. – {- [ (14 - 7) - (32 - 41)]}
= – {- [ (14 - 7) - (-9)]} Solving inner small brackets
= – {- [ (7) +9]} Solving inner small brackets
= – {- [ 16 ]} Solving outer square brackets
= – {- 16 } Solving curly brackets
= + 16 (-*-= +)
i. – [(-8 + 3) + (- 21 – 12)]
= – [(-8 + 3) + (- 33)] Solving inner small brackets
= – [(-5 - 33)] Solving inner small brackets
=– [( - 38 )] Solving outer square brackets
= + 38 (-*-= +)
j. 500 – {( 6 – 18 + 4 + 3 + 16 - 10 – 2) – 5 }
= 500 – {( 6 + 4 + 3 + 16 – 18 -10 – 2) – 5 } Solving inner small brackets
= 500 – {( 29 – 30) – 5 } Solving inner small brackets
= 500 – {( – 1) – 5 } Solving inner small brackets
= 500 – { – 6} Solving curly brackets
= 500 + 6 (-*-= +)
= 506
k. (9 + 7 – 2 + 4) – ( 9 -12 )

Claire bought 6 packs of baseball cards. Each pack had the same number of cards. If Claire bought 48 baseball cards in all, how many cards were in each pack.
Answer:
8 baseball cards were in each pack
Step-by-step explanation:
Since she has a total of 48 cards and each of the 6 packs had the same amount you would just do 48 divided by 6 which is 8. So there were 8 baseball cards in each pack

Answer:
9. Correct 12. Incorrect, it's D
Step-by-step explanation:
9. There is a 1:2 ratio of blue to red paint to create the shade of purple, so 6:12 would follow the 1:2 ratio so it's correct.
12. 6:14 can be simplified to 3:7 ratio. 8:16 doesn't follow 3:7 (it follows 1:2) so it can't be the right answer. 12:28 follows the ratio so it's right.
Jill cuts a piece of cardboard in the shape of a trapezoid.The area of the is 43.5sp cm. If bases are cm and 8.5cm long,what is the height.
Answer:
7.25cm
Step-by-step explanation:
Let the complete question be;
Jill cuts a piece of cardboard in the shape of a trapezoid. The area of the is 43.5sp cm. If bases are 3.5cm and 8.5cm long, what is the height.
Area of a trapezoid = 1/2(a+b)*h
a and b are the parallel sides (bases)
h is the height
Given
a = 3.5cm
b = 8.5cm
A = 43.5 sq.cm
Required
Height h
Substitute the given values into the expression
Area of a trapezoid = 1/2(a+b)*h
43.5 = 1/2(3.5+8.5)*h
43.5 = 1/2 * 12h
43.5 = 6h
h = 43.5/6
h = 7.25cm
Hence the height is 7.25cm
what is the missing angle in a triangle with angle measures of 15 degrees and 70 degrees
Answer:
95
Step-by-step explanation:
A triangle must always equal 180, so if you take the values of 15 and 70, you get 85.
Then, you take 180 and subtract 85.
This leaves you with 95

pls help asap !!!!!!!!!!!!!!!!!!!!!
Answer:
For the 1st one: 63
For the second one: 99
Step-by-step explanation:
This is because to find the perimeter, you have to do length+length+width+width=area
So you do 77+77+x+x=280, this should get you x=63
For the second one, to find area you do length×width=area
So you do 59×x=5841 and should get 99.

Answer:
1.x=45,2.x=16
Step-by-step explanation:
1.
x+90+45=180(Angles in an adjacent angle)
x=180-135
x=45
2.
7x=112(vertically opposite angle)
x=112/7
x=16
First question refers to the supplementary angle theorem.
To find x, we need to refer to the other angles around it and use it to subtract it from 180°.
90 + 45 + x = 180
135 + x = 180
x = 180 - 135
x = 45°
Second question refers to the vertical angles theorem, where it states that the angles that face in opposite directions are the same.
7x = 112
x = 112 ÷ 7
x = 16°

Order 2.000 D5W IV to infuse over 12 hoursThe drop factor is 15 gtt/. Calculate the rate in gtt / min
Answer:
42gtt/m
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Flow rate in gtt/min = (Total fluid in ml × Drop factor) ÷ (Total hours × 60)
Where, Total fluid in ml = 2,000ml
Drop factor = 15gtt/m
Total hours = 12hours
By putting the following value in the formula, we get
Flow rate in gtt/min = (2,000 × 15) ÷ (12 × 60)
= 30,000 ÷ 720
= 41.67 or 42gtt/m

Zoe supplies costumes to a number of theater companies. She
recently provided 20 different hats, including 4 fedoras.
Considering this data, how many of the next 30 hats requested
from Zoe's inventory should you expect to be fedoras?
Answer:3
Step-by-step explanation:
The 6 fedoras expect if next 30 hats requested from Zoe's inventory, and She recently provided 20 different hats, including 4 fedoras.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
The ratio of hats to fedoras = 20:4
Let's suppose Zoe's inventory, should expect to x fedoras
20/4 = 30/x
x = 30/5
x = 6
Thus, the 6 fedoras expect if next 30 hats requested from Zoe's inventory, and She recently provided 20 different hats, including 4 fedoras.
