Answer:
Angle A = 30.8
Angle B = 33.2
Step-by-step explanation:
180 - 116 = 64
This means that the other two angles need to add up to 64.
I just plugged in numbers until it worked.
I got that x = 14.6
2x + 4
2(14.6) + 4
29.2 + 4
33.2
3x - 13
3(14.6) - 13
43.8 - 13
30.8
Those are your angles. To make sure they are correct you just need to add up all the angles and make sure that they equal to 180.
116 + 33.2 + 30.8 =
180
On considère l'énoncé suivant :150 garçons et 250 filles sont inscrits au conservatoire. 20 % des garçons et 30 % des filles sont pianistes.
Question complète:
150 garçons et 250 filles sont inscrits au conservatoire. 20% des garçons et 30% des filles sont pianistes. Calculer le pourcentage de pianistes au conservatoire
Répondre:
26,25%
Explication étape par étape:
Nombre de garçons = 150
Nombre de filles = 250
Pianiste masculin = 20% des garçons
Pianiste masculin = 0,2 * 150 = 30 garçons
Pianiste féminine: = 30% des filles
Pianiste féminine = 0,3 * 250 = 75 filles
Nombre total de pianistes:
(30 + 75) = 105 pianiste
Population du conservatoire = (150 + 250) = 400
Pourcentage de pianiste:
105/400 * 100%
0,2625 * 100%
26,25%

Mayne is 28 years old. She is 12 years older than 2/3 of Laurels age. Which equation can be used to find Laurels age, a?
Answer:
B. ⅔a + 12 = 28
Step-by-step explanation:
Here are the options to this question
) ⅔ + 12a = 28
b) ⅔a + 12 = 28
c) ⅔a + 12a = 28
d) -⅔a + 12 = 28
Mayne's age can be represented with this equation =
28 = 12 + 2/3a
where a = laurels age

Answer:
Middle answer is right
Step-by-step explanation:
The first answer is obliviously wrong so therefore it is the last two options
-(x+1)^2
= -(x^2+2x+1)
= -x^2-2x-1-3 (add the -3)
= x^2-2x-4
y intercept make x=0 therefore y=-4
AOS is x= -b/2a
x=2/2 which is 1
therefore it isthe middle answer

933 months

months
Answer:
933mounths=77years and 9 mounts
Answer:
[tex]77\frac{3}{4}[/tex] years = 933 months
77.75 years = 933 months
Step-by-step explanation:
1 year = 12 months
y = 933 months
[tex]\frac{1}{12}= \frac{y}{933}[/tex]
12 × y = 933 × 1
12y = 933
12y ÷ 12 = 933 ÷ 12
y = 77.75

()) There are two cubes. The first cube has a volume of 1,000 cubic units. The second cube is smaller than the first, with sides only half as long. What is the volume of the second cube? D) cubic units Submit
Answer:
125 units^3
Step-by-step explanation:
Volume is l*w*h = V. A cube has all equal sides so wecan divide 1000 by 3 and get our side lengths.
You then divide the sides by 2 because the question says the second cubes sides are half the size
5*5*5 = 125
The volume of the second cube is 125 units³.
What is volume?In mathematics, ‘Volume’ is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
Given that a cube has volume 1000 units³ and another smaller cube has smaller volume has side only half as long.
We need to find the volume of the second cube,
So, let the side of the first cube be x,
We know that the volume of a cube = side³
Therefore,
x³ = 1000
x = ∛1000
x = 10 units
Therefore, the second cube will have a side of 10/2 = 5 units
Volume of second cube = 5³ = 125 units³.
Hence the volume of the second cube is 125 units³.

Use a Pythagorean Triple to find x.
Answer:
x = 51
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² = 45² + 24² = 2025 + 576 = 2601 ( take the square root of both sides )
x = [tex]\sqrt{2601}[/tex] = 51
Answer:
x = 51.
Step-by-step explanation:
The triple you require is 17-15-8
We have x-45-24
- that is three times each number in the triple.
So x = 3*17 = 51.

Use the following diagram to find the angle measures of the triangle, rounded to the nearest degree.
m∠A=
m∠B=
m∠C=
Answer:
m∠A = 30°
m∠B = 80°
m∠C = 70°
Step-by-step explanation:
By applying cosine rule in the given triangle,
b² = a² + c² - 2ac[cos(∠B)]
From the given triangle,
a = 14 m
b = 28 m
c = 24 m
(28)² = (14)² + (24)² - 2(14)(24)cos(B)
784 = 196 + 576 - 672cos(∠B)
cos(∠B) = 0.1786
∠B = [tex]\text{cos}^{-1}(0.1786)[/tex]
∠B = 79.71°
∠B = 80°
By applying sine rule in the given triangle,
[tex]\frac{\text{sinA}}{a}= \frac{\text{sinB}}{b}= \frac{\text{sinC}}{c}[/tex]
[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}= \frac{\text{sinC}}{24}[/tex]
[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}[/tex]
[tex]\text{sinA}= \frac{\text{sin(79.71)}\times 14}{28}[/tex]
sinA = 0.491958
A = 29.47°
A ≈ 30°
By applying triangle sum theorem,
m∠A + m∠B + m∠C = 180°
30° + 80° + m∠C = 180°
m∠C = 70°

Answer:
a
Step-by-step explanation:
Given
u = (x₁, y₁, z₁ ) and v = (x₂, y₂, z₂ ) then the dot product is
u • v = (x₁ x₂ ) + (y₁ y₂ ) + (z₁ z₂ )
Then
v • w
= (5 × 9) + (- 4 × - 2) + (4 × 7)
