Answer:
Step-by-step explanation:
Tanisha, Elicia, and Ajua are cousins. Tanisha is twice as old as Ajua, and Elicia is two years older than Tanisha. The sum of all their ages is 37. Use variable expressions and calculate the age of each girl
Let us represent:
The age of :
Tanisha = a
Elicia = b
Ajua = c
Tanisha, Elicia, and Ajua are cousins. Tanisha is twice as old as Ajua
a = 2c
c = 2/a
Elicia is two years older than Tanisha.l
b = a + 2
The sum of all their ages is 37.
a + b + c = 37
We substitute
a + a + 2 + 2/a = 37
2a + 2 + 2/a = 37
Use variable expressions and calculate the age of each girl
Find the value of X round to the nearest 10th law of cosines.
Image of triangle is missing, so i have attached it.
Answer:
x = 18
Step-by-step explanation:
From the diagram attached, we can see that the 3 given sides have dimensions of x, 16 and 30.
Also, we see the angle opposite the dimension of x is 30°
Thus,we can use law of cosine to fjnd the value of x. Thus:
x² = 16² + 30² - 2(16 × 30)cos 30
x² = 256 + 900 - (960 × 0.866)
x² = 324.64
x = √324.64
x = 18.02
Approximating to the nearest tenth gives; x = 18

A triangle has side lengths of 23 in, 6 in, and 28 in. classify it as acute right or obtuse
Answer:
In this case, the side lenghths don't even form a triangle. Since that is not an option, the triangle would be acute.
Step-by-step explanation:
if c^(2 )> a^(2)+b^(2) then the triangle is obtuse.
if c^(2 )< a^(2)+b^(2) then the triangle is acute.
if c^(2 )= a^(2)+b^(2) then the triangle is right
Hope this helps :)

Are the triangles below obtuse, acute, or right?
Answer: A is right. B is acute, C is obtuse, and D is right.
Step-by-step explanation:
The right triangles have the square in the corner.
Triangle C is a little bit bigger than a right triangle.
Triangle B is acute because its smaller than a right triangle.

f(x) = —x^2 – 3x
Find f(10)
Step-by-step explanation:
f(x) = —x^2 – 3x
f(10)={-10}²-3×10=100-30=70
Answer:
f(10) = 70
Step-by-step explanation:
In this question, plug in "10" to "x" and solve.
Solve:
f(10) = -(10)^2 - 3(10)
f(10) = 100 - 3(10)
f(10) = 100 - 30
f(10) = 70
Your final answer would be f(10) = 70

What is the measure of A?
What is the measure of B?
<A = 72°
<B = 108°
Explanation :<A = <C
(5y - 3)° = (3y + 27)°
5y-3y = 27 + 3
2y = 30
y = 15
<A = (5y - 3)°
<A = (5 x 15) - 3
<A = 75 - 3
<A = 72°
<B + <A = 180°
<B + 72° = 180°
<B = 180° - 72°
<B = 108°
the mass of a plastic triangle is 3g and rhe mass of a plastic square is 7 g Samson has a collection of plastic triangles and squares if there are 14 triangles and squares altogether and their combined mass is 58 g calculate how many triangles and how many squares Samson has.
Answer:
4 squares
10 triangles
Step-by-step explanation:
t=3g
s=7g
t+s=14 t=14-s
3t+7s=58
substitute
3(14-s)+7s=58
42-3s+7s=58
reduce
4s+42=58
4s=16
s=4
t=14-4=10

Cristina realizo sus pagos con su tarjeta de crédito, si el primero fue de 5.500.000 y el segundo por 3. 750 000
Answer:
Ver explicación
Step-by-step explanation:
La pregunta carece de detalles. Sin embargo, una posible pregunta podría ser calcular el total de pagos realizados con su tarjeta de crédito.
Para hacer esto, simplemente sumamos los dos pagos.
[tex]Pago\ 1 = 5,500,000[/tex]
[tex]Pago\ 2 = 3,750,000[/tex]
Entonces tenemos:
[tex]Total = Pago\ 1 + Pago\ 2[/tex]
[tex]Total = 5,500.000 + 3,750,000[/tex]
[tex]Total = 9,250,000[/tex]

A group of students are going on a field trip. if the group takes 3 vans and 1 car, 22 students can be transported. if the group takes 2 vans and 4 cars, 28 students can be transported. write and solve a system of equations to represent the situation. fill in the blanks to indicate the number if students that can fit in each van and car?
Answer:
6 students.
Step-by-step explanation:
3v + c = 22 ---> c = 22 - 3v
2v + 4c = 28 ---> 2v + 4(22 - 3v) = 28
2v + 88 - 12v = 28
-10v + 88 = 28
- 88 - 88
- 10v = - 60
v = 6 students

Answer:
204
Step-by-step explanation:
The area of the top triangle = 5*12/2 = 30
The area of the bottom triangle = 30
The hypotenuse of the top triangle is
5^2 + 12^2 = hypotenuse^2
25 + 144 = hypotenuse^2
169 = hypotenuse squared.
hypotenuse = sqrt(169)
hypotenuse = 13
Now the back face = 13 * 8 = 104
The area of the left side rectangular face = 5*8 = 40
The total area = 30 + 30 + 104 + 40 = 204
Solve the following system of equations using the substitution method
y - 3x = 12
y = - 3
Answer:
x = 5
y = -3
as an ordered pair: (5,-3)
Step-by-step explanation:
if y = -3, then replace y in the first equation with -3.
-3 - 3x = 12
move -3 over to the other side by adding 3 to both sides.
3x = 15
x = 5
y = -3
Answer:
x = -5
y = -3
Step-by-step explanation:
Two equations
Solve using substitutition
y = -3
y - 3x = 12
_____________________
Since the first equation has y alone, we can plug it into the second equation for y.
(-3) - 3x = 12
-3 - 3x = 12
Add 3 to both sides :
-3x = 15
Divide -3 from both sides to get x alone :
x = -5
Now that we have x, plug it into x in the second equation :
y - 3(-5) = 12
y + 15 = 12
Solve for y :
Subtract 15 from both sides :
y = -3
