The number of boys and girls in a class are in the ratio 5:4. If the
number of boys is 9 more than the number of girls, then number of
boys is 9
Answer:
no.of boys is 45
Step-by-step explanation:
here, let the number of boys and girls be 5x and4x
ATQ,
5x=4x+9
or,5x-4x=9
or,x=9
then, the number of boys is 9×5=45
and the number of girls is 9×4=36..

Find the equation of the line that passes through points A and B.
y
X A (4, 7)
B (2, 3)
Answer:
y = 2x - 1.
Step-by-step explanation:
The slope = (7-3)/(4-2)
= 4/2
= 2.
y - y1 = m(x - x1)
Here m = 2 , x1 = 2 and y1 = 3. So we have:
y - 3 = 2(x - 2)
y = 2x - 4 + 3
y = 2x - 1.
We have used the point (2, 3) to find the equation but we could have used (4, 7). We would have got the same answer.
Answer:
y - 3 = 2(x - 2)
Step-by-step explanation:
As we move from Point B (2, 3) to Point A (4, 7), we see x increasing by 2 from 2 to 4 and y increasing by 4 from 3 to 7. Hence the rise is 4 and the run is 2, which means that the slope of this line is m = rise / run = 4/2 = 2.
Using the point-slope formula y - k = m(x - h) and the point (2, 3), we get:
y - 3 = 2(x - 2)
The ratio of the heights of two similar cylinders is 1:3. If the volume of the smaller cylinder is 67cm3, find the volume of the larger cylinder. (Create two proportions, set them equal to each other and solve for x)
Answer:
solution given:
similar cylinders ratio 1:3
let the ratio be 1x and 3x respectively:
according to the question:
x/3x=volume of (smaller cylinder/big cylinder)
Volume of big Cylinder=67cm³×3=201cm3
201cm³ is your answer
A watering can contained 512 quarts water. After all the plants were watered, only 4 cups remained. How many cups of water were used to water the plants?
Answer:
2044 cups
Step-by-step explanation:
number of cups left = number of cups in the watering can - number of cups remaining
convert the capacity of the watering can to cups
1 quart = 4 cups
512 x 4 = 2048
2048 - 4 = 2044

Triangle ABC is isosceles with AB=CB. Circle M is inscribed in Triangle ABC such that it is tangent at points D, E, and F. If the length of BF is twice the length of CF and the perimeter of Triangle ABC is 32 inches, then determine the length of side BC in inches.
Answer:
The answer is "12 inches".
Step-by-step explanation:
Please find the image file of the graph.
We know [tex]AE = CF \ and \ EB = FB[/tex] so because the triangle is isosceles.
[tex]EB = 2x, FB = 2x,\ and \ CF = x[/tex] when [tex]AE[/tex] is called by [tex]x[/tex].
We know that [tex]AE = AD = x[/tex] since E and D are tangent points to a circle.
They have [tex]CD = CF = x[/tex] since D and F are tangent points only to circle.
Thus, if the perimeter is 32, the following is the result:
[tex]\to AE + EB + BF + FC + CD + DA = 32\\\\\to x + 2x + 2x + x + x + x = 32\\\\\to 8x = 32\\\\\to x = 4[/tex]
Therefore the length of [tex]BC = BF + FC = 2x + x = 3x = 12\ inches[/tex]

A discipline committee is selected by placing the names or 12 teachers in a bag and than randomly drawing 3 of the names it there are 7 math teachers and 5 english teachers what is the probility that the committee will be made up of all math teachers a7/44 b7/12 c35/288 d7/288
Answer:
b
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
probability that the committee will be made up of all math teachers = total number of maths teacher / total number of teachers
7 / 12
What is the area of this kite? A) 20 square meters
B) 36 square meters
C)40 square meters
D) 80 square meters
Answer:
D
Step-by-step explanation:
Answer:
C. 40 square meters
Step-by-step explanation:
The area for a kite can be figure out with this formula. pq/2. Substitute p for 8 & q for 10.
A = pq/2 {Substitutions made}
A = (8 * 10)/2 {Multiply 8 by 10 to get 80.}
A = 80/2 {Divide 80 by 2 to get 40.}
A = 40 square meters
The area of this kite of 40 square meters, which is C.

I will crown u and give you 20 extra points
Answer:
See below for answers and explanations
Step-by-step explanation:
4) 35° and x° are vertical angles, so they are congruent to each other. Therefore, x°=35°. Since y°+y°+35°=180° since they are all supplementary to each other, then y°=72.5° when solved.
5) A is true. Think of two adjacent angles measured 60° and 30° that are next to each other. They add up to 90° as well.
B isn't true. Vertical angles are congruent to each other, not supplementary.
C isn't true. The statement contradicts itself. Complementary angles add up to 90° while supplementary angles add up to 180°
Please help me i cant figure it out im stuck
what goes in the question mark box?
Answer:
y = 4x - 31
Step-by-step explanation:
Parallel slope (m) = 4
(5, -11)
y - y1 = m(x - x1)
y + 11 = 4(x - 5)
y + 11 = 4x - 20
y = 4x - 31
A 3ft child casts a 2ft shadow at the same time a tree casts a shadow that is 6ft long how tall is the tree?
Answer:
[tex]h_t=9ft[/tex]
Step-by-step explanation:
From the question we are told that:
Height of child [tex]h_c=3ft[/tex]
Height of child's shadow [tex]h_c_s=2ft[/tex]
Height of tree's shadow [tex]h_t_s=6ft[/tex]
Since position of Sun remains constant
Generally the equation for Height of tree h_t mathematically given by
[tex]h_t=f_{ts}\frac{h_c}{h_c_s}[/tex]
[tex]h_t=6*\frac{3}{2}[/tex]
[tex]h_t=9ft[/tex]

Cual es el mejor estimado de la solucion de lsistema de ecuciones lineales graficadas. y=4x-4 2x+y=5
Answer:
x = 1.5, y = 2
Step-by-step explanation:
Cuando tenemos un sistema de ecuaciones lineales, para resolverlo gráficamente simplemente debemos graficar ambas líneas y ver en que punto las líneas se interceptan.
En este caso, tenemos las líneas:
y = 4*x - 4
2*x + y = 5
El primer paso puede ser escribir ambas líneas en forma estándar, así será más fácil graficarlas.
Para ello, aislamos y en ambas ecuaciones:
y = 4*x - 4
y = 5 - 2*x
Ahora que tenemos ambas líneas debemos graficarlas en un mismo eje de coordenadas, y buscar el punto en donde ambas líneas se interceptan.
Un gráfico de este sistema se puede ver abajo:
Viendo el gráfico, podemos estimar que la solución del sistema es el punto:
(1.5, 2)
Es decir, la solución es:
x = 1.5
y = 2
Solamente para ser completos, también podemos resolver el sistema analíticamente y ver si la solución que encontramos gráficamente es aceptable.
Para ello escribimos el sistema:
y = 4*x - 4
y = 5 - 2*x
Como y esta aislada en ambas ecuaciones, tendremos:
4*x - 4 = y = 5 - 2*x
4*x - 4 = 5 - 2*x
Ahora podemos resolver esto para x.
4*x + 2*x = 5 + 4
6*x = 9
x = 9/6 = 3/2 = 1.5
Remplazando este valor de x en cualquiera de las dos líneas obtendremos el valor de y de la solución:
y = 4*x - 4 = 4*1.5 - 4 = 6 - 4 = 2
Así probamos analíticamente que la solución es x = 1.5, y = 2.
