Si del botellón se pueden servir 45 vasos, la cantidad de agua que cabe en el botellón es: a) 54 litros b) 12 litros c) 5,4 litros d) 0,54 litros
Answer:
c) 5,4 litros
Step-by-step explanation:
Un vaso de agua contiene 0,12 litros de agua.
Una botella contiene 45 vasos de agua.
El volumen completo de agua de la botella se distribuye en 45 vasos por igual.
Entonces,
[tex]0.12\ \text{L}\times 45=5.4\ \text{L}[/tex]
Por lo tanto, la cantidad de agua en la botella que se puede usar para servir 45 vasos es de 5.4 L.

Andre and Priyabare tracking the number of steps they walk. Andre records that he can walk 6000 steps in 50 minutes. Priya writes the equation y=118x, where y is the number of steps and x is the number of minutes she walks, to describe her step rate. This week, Andre and Priya each walk for a total of 5 hours. Who walks more step?How many more?
Answer:
Andre walks 600 more steps than Priyabare
Step-by-step explanation:
Andre is 36,000 minutes while Priyabare walks 35,400. 1st you get the 6000 steps in 50 minutes from Andre and divide the 6000 by 50 to get 120 which you then multiply by 300 (minutes which is 5 hours) and get 36000. Then for Priyabare you multiply 118 by 300 as well (Again because equals 5 hours) and you will get 35,400 meaning Andre walked 600 more steps if you subtract the two.

Answer:
∠1 ≅ ∠2 ⇒ proved down
Step-by-step explanation:
#12
In the given figure
∵ LJ // WK
∵ LP is a transversal
∵ ∠1 and ∠KWP are corresponding angles
∵ The corresponding angles are equal in measures
∴ m∠1 = m∠KWP
∴ ∠1 ≅ ∠KWP ⇒ (1)
∵ WK // AP
∵ WP is a transversal
∵ ∠KWP and ∠WPA are interior alternate angles
∵ The interior alternate angles are equal in measures
∴ m∠KWP = m∠WPA
∴ ∠KWP ≅ ∠WPA ⇒ (2)
→ From (1) and (2)
∵ ∠1 and ∠WPA are congruent to ∠KWP
∴ ∠1 and ∠WPA are congruent
∴ ∠1 ≅ ∠WPA ⇒ (3)
∵ WP // AG
∵ AP is a transversal
∵ ∠WPA and ∠2 are interior alternate angles
∵ The interior alternate angles are equal in measures
∴ m∠WPA = m∠2
∴ ∠WPA ≅ ∠2 ⇒ (4)
→ From (3) and (4)
∵ ∠1 and ∠2 are congruent to ∠WPA
∴ ∠1 and ∠2 are congruent
∴ ∠1 ≅ ∠2 ⇒ proved

An observation tower is 75 m high. A support wire is attached to the tower 20 m from the top. If the support wire and the ground form an angle of 46 degrees, what is the length of the support wire, to the nearest thousandth?
Answer: 76.46 m
Step-by-step explanation:
Height of tower = 75m
Support wire 20 m from top
Angle formed (α) = 46°
Using Pythagoras :
Sinα = opposite / hypotenus
Height used = height of tower - 20 m from top
Height = opposite = (75 - 20)m = 55m
Hypotenus = Length of support wire
Sin 46 = 55m / hypotenus
Hypotenus * sin 46 = 55
0.71934 * hypotenus = 55
Hypotenus = 55/0.71934
Hypotenus = 76.458976
Hence, Lenght of support wire = 76.46 m

How to determine the remainder in dividing the polynomial P(x) by a divisor x-1?
Answer:
Calculate P(1)
Step-by-step explanation:
Given
P(x)
[tex]Divisor = x - 1[/tex]
Required
How to determine the remainder
First, you equate the divisor to 0 to solve for x
i.e.
[tex]x - 1 = 0[/tex]
[tex]x = 1[/tex]
Next, substitute 1 for x in P(x)
Then solve for P(1)
Take for instance;
If
[tex]P(x) = x^3 - x^2 - 1[/tex]
Substitute 1 for x
[tex]P(1) = 1^3 - 1^2 - 1[/tex]
[tex]P(1) = 1 - 1 - 1[/tex]
[tex]P(1) = - 1[/tex]
Hence, the remainder is -1

what is the answer to this? 5(g+4)>15
Answer:
g > -1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(g+4)=15
(5)(g)+(5)(4)=15(Distribute)
5g+20=15
Step 2: Subtract 20 from both sides.
5g+20−20=15−20
5g=−5
Step 3: Divide both sides by 5.
5g/5 = −5/5
G > -1
The solution of the inequality 5(g+4)>15 is g> -1.
Given Inequality:
5(g+4)>15
To solve the inequality, divide the inequality by 5
5(g+4) / 5 >15 / 5
g + 4 > 3
Now, subtract 4 from both side of inequality as
g + 4 - 4 > 3-4
g > -1.
Therefore, the solution is g > -1.

Triangle ABC is shown with its inscribed circle drawn. The measure of angle ECF is 72 degrees. What is the measure of angle EGF? Explain or show your reasoning.
Answer:
108°
Step-by-step explanation:
CB and CA are tangents to the circle at points E and F respectively. GE and GF are radii of the circle with center G.
Since, radii of a circle are perpendicular to the tangents at the point of contacts.
[tex] \therefore GE \perp CB\\\\
\& \:GF \perp CA\\\\
m\angle GEC =m\angle GFC = 90\degree \\\\[/tex]
In quadrilateral GECF, by interior angle sum property:
[tex] m\angle C + m\angle E + m\angle F + m\angle EGF = 360\degree \\\\
\therefore 72\degree + 90\degree + 90\degree + m\angle EGF = 360\degree \\\\
\therefore 252\degree + m\angle EGF = 360\degree \\\\
\therefore m\angle EGF = 360\degree - 252\degree \\\\
\therefore m\angle EGF = 108\degree \\[/tex]
Answer:
108°Step-by-step explanation:
Since GE ⊥ BC and GF ⊥ AC,∠GEC = ∠GFC = 90°Sum of 4 angles is 360°, therefore:
∠ECF + ∠EGF = 360° - 180°∠EGF = 180° - 72° ∠EGF = 108°
