The vertex angle of an isosceles triangle is three times the measure of either base angle. Find the area if the measure of the congruent sides are 14 in
Answers
Answer:
[tex]Area = 93.21in^2[/tex]
Step-by-step explanation:
Given
[tex]\theta \to[/tex] vertex angle
[tex]\alpha \to[/tex] base angle
[tex]\theta = 3\alpha[/tex]
[tex]l = 14in[/tex] -- congruent sides
Required
The area of the triangle
First, calculate the angles
[tex]\theta + \alpha + \alpha = 180^o[/tex] ----- angles in an isosceles triangle
Substitute [tex]\theta = 3\alpha[/tex]
[tex]3\alpha + \alpha + \alpha = 180^o[/tex]
[tex]5\alpha = 180^o[/tex]
Divide both sides by 5
[tex]\alpha = 36^o[/tex]
Recall that: [tex]\theta = 3\alpha[/tex]
[tex]\theta = 3 * 36^o[/tex]
[tex]\theta = 108^o[/tex]
The area is then calculated as:
[tex]Area = \frac{1}{2}l^2 \sin(\theta)[/tex]
[tex]Area = \frac{1}{2}*14^2 \sin(108^o)[/tex]
[tex]Area = \frac{1}{2}*196 *0.9511[/tex]
[tex]Area = 93.21in^2[/tex]
A jar is full of gumballs and Hershey’s kisses. 2/3 of the jar is gumballs. 3/5 of these gumballs are red. What fraction of the whole jar are the red gumballs?
Answers
Answer:
[tex]\frac{2}{5}[/tex] of the jar contains red gumballs
Step-by-step explanation:
Hi there!
What we know:
[tex]\frac{2}{3}[/tex] of the jar is gumballs[tex]\frac{3}{5}[/tex] of the gumballs are redTo find the fraction of red gumballs in the whole jar, multiply the fractions:
Red gumball fraction × Total gumball fraction
[tex]= \frac{3}{5}*\frac{2}{3}\\= \frac{2}{5}[/tex]
Therefore, red gumballs contain [tex]\frac{2}{5}[/tex] of the whole jar.

A 30-foot ladder is set against the side of a house so that it reaches up 24 feet. If Elizabeth grabs the ladder at its base and pulls it 3 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 21 ft.) Round to the nearest tenth of a foot.
Answers
Use the Pythagorean theorem to calculate the distance from the wall the ladder originally is:
x = sqrt(30^2 - 24^2)
x = sqrt(900-576)
x = sqrt(324)
x = 18
The ladder was originally 18 feet from the wall. Moving the ladder 3 feet further away makes the new distance 18 + 3 = 21 feet.
Now use the Pythagorean theorem again to find the new height of the ladder.
Height = sqrt(30^2 - 21^2)
Height = sqrt(900 - 441)
Height = sqrt(459)
Height = 21.42
Rounded to the nearest tenth = 21.4 feet.

Juan necesita para su coche verde 3dl y 75 ml de aceites,y para su coche azul 13cl y 5ml.¿Cuantos hl necesita en total? ¿Tendrá suficiente con una lata de medio litro?
Answers
Answer:
1. Juan necesita 0,0051 hl en total.
2. Juan no tendrá suficiente con una lata de medio litro.
Step-by-step explanation:
1. Para calcular el volumen total en hl, primero debemos convertir todas las unidades a hl.
Para el coche verde:
[tex] V_{1} = 3 dl*\frac{1 hl}{1000 dl} = 0,003 hl [/tex]
[tex] V_{2} = 75 ml*\frac{1 hl}{100000 ml} = 0,00075 hl [/tex]
Para el coche azul:
[tex] V_{3} = 13 cl*\frac{1 hl}{10000 cl} = 0,0013 hl [/tex]
[tex] V_{4} = 5 ml*\frac{1 hl}{100000 dl} = 0,00005 hl [/tex]
Ahora, para encontrar el volumen total debemos sumar todos los volúmenes anteriores:
[tex] V_{T} = V_{1} + V_{2} + V_{3} + V_{4} = 0,003 hl + 0,00075 hl + 0,0013 hl + 0,00005 hl = 0,0051 hl [/tex]
Por lo tanto, Juan necesita 0,0051 hl en total.
2. Luego, para saber si tendrá suficiente con una lata de medio litro, debemos convertir el volumen total de hl a l:
[tex] V_{T} = 0,0051 hl*\frac{100 l}{1 hl} = 0,51 l [/tex]
Entonces, dado que el volumen total es 0,51 litros Juan no tendrá suficiente con una lata de medio litro porque necesita cubrir 0,01 litros más.
Espero que te sea de utilidad!

What is the domain of y = x + 1?
Answers
Answer:
[0, infinity
Step-by-step explanation:
It's essential to type "sqrt(x)" or "√x," which are vastly different from the linear function y = x + 1.
The domain of the square root function is [0, infinity).
Adding 1 to this merely shifts the entire graph up 1 unit.
So the domain of y = √x + 1 is the same as before: [0, infinity
