Answer:
7. A=48
8.B=30
9. C=188
10. D=18
11. X=32
12.Y=40
Step-by-step explanation:
Answer:
7. [tex]a=48[/tex]
8. [tex]b=30[/tex]
9. [tex]c = 188[/tex]
10. [tex]d = 18[/tex]
11. [tex]x = 32[/tex]
12. [tex]y = 40[/tex]
Step-by-step explanation:
Let's do something called cross-multiplication. It's exactly what it sounds like, we multiply the top number with the denominator across the multiplication.
[tex]\frac{33}{a} = \frac{11}{16}[/tex]
[tex]11 a = 33(16)[/tex]
[tex]11a = 528[/tex]
Now we can simplify.
[tex]a=48[/tex]
So we got the answer for the first one. We can keep doing the same thing for the others.
A line passes through the origin and has a slope of 2/3
Answer:
y=2/3x
Step-by-step explanation:
the origin is the point (0,0) and the given slope is 2/3
the equation for slope-intercept form is y=mx+b, where m is the slope and b is the y intercept
the slope is given, meanwhile, the y intercept is the point where the line passes through the y axis, and the x value is 0.
In this question, we actually have the y intercept given, which is (0,0)
we can put it all together then:
y=2/3x+0
or
y=2/3x
Hope this helps :)

Which statement is true when comparing how a student would complete the solution for the linear equation -2x + 3 = 6 to how the student would complete the solution for the linear inequality -2x + 3 < 6?
Completing the solution for the equation is the same as completing the solution for the inequality. The student would divide both sides by -2 in either case.
Completing the solution for the equation is the same as completing the solution for the inequality. The student would divide both sides by -2 in either case.
Completing the solution for the equation is the same as completing the solution for the inequality. The student would multiply both sides by -2 in either case.
Completing the solution for the equation is the same as completing the solution for the inequality. The student would multiply both sides by -2 in either case.
Completing the solution for the equation is not the same as completing the solution for the inequality. The student would divide by -2 to complete the solution for the equation and would divide by -2 and change the less than sign for the inequality to greater than.

Answer: 57
Step-by-step explanation: The shorter segment of the lines that cross the centroid are always half of the longer segment. This means segment QM equals 19, since it is half of 38. When 38, and 19 are added together, it equals 57.
Se ha decidido repoblar con 150 000 árboles una zona asolada por un incencio. Se quieren plantar los árboles formando un cuadrado con el mismo número de árboles y la misma separación entre ellos. ¿Cuántos árboles se podrán plantar para formar el cuadrado más grande posible?
Responder :
Se plantarán 149769 árboles
Explicación paso a paso:
Dado que:
Número de árboles a plantar = 150.000
Los árboles deben disponerse para formar un cuadrado;
La cantidad de árboles que se pueden plantar para hacer el cuadrado más grande posible:
Área de un cuadrado = s²
Dónde; s = Longitud de cualquier lado; ya que todos los lados son iguales.
El mayor número de árboles que se pueden plantar es el cuadrado perfecto más alto hasta 150.000.
Esto se puede obtener tomando la raíz cuadrada de 150000
Cuadrado (150.000)
= 387,29833
El cuadrado del número entero da el valor cuadrado perfecto más alto antes de 150 000
Por lo tanto,
s = 387 =; 387
Cantidad total de árboles; s² = 387² = 149769

Answer:
x°=48°
Step-by-step explanation:
angle Y=x°
angle Z= angle y, because equal side of the angles are equal.
so, angle X +angleY+ angle Z=180° ( angle sum property of triangles)
therefore 84°+x°+x°=180°
2x°=180° -84°
2x°=96°
x°=48°

The ratio of adults to kids in a school is 3 : 7. If there is a total of 200 people, how many of them are students? *
Answer:
60 students 140 adults
Step-by-step explanation:
so 200 into 3 : 7
first we just do this: 200 ÷ (3+7) = 200 ÷ 10 = 20
so a 1 in the ratio is 20 people
and theres 3 : 7
so 3 * 20 = 60
7 * 20 = 140
60 kids to 140 adults
Answer:
140 are students
Step-by-step explanation:
let k = number of kids
set up proportion based on 7 out of 10 are kids
7/10 = k/200
cross-multiply: 10K = 1400

Solve the following for the variable x.
3x - 16 = 38
Answer: x= 18
Step-by-step explanation:
3x - 16 = 38
38 + 16 = 54
3x/3 = 54/3
X= 18
Step-by-step explanation:
[tex] \tt{3x - 16 = 38}[/tex]
We want to remove the 16 first. So , Since the original equation is - 16 , we are going to use the oppsite operation and add 16 to both sides.
⟶ [tex] \tt{3x - 16 + 16 = 38 + 16}[/tex]
Simplify ! - 16 + 16 = 0 on the left. 38 + 16 = 54 on the right.
⟶ [tex] \tt{3x = 54}[/tex]
Now , we need to think how to remove the coefficient 3. Since the opposite of multiplication is division , we are going to divide both sides by 3.
⟶ [tex] \tt{ \frac{3x}{3} = \frac{54}{3}} [/tex]
Simplify ! 3 / 3 = 1 on the left and 54/3 = 18 on the right . So, our answer is 18.
[tex] \pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = 18}}}}}}}[/tex]

Step-by-step explanation:
Angle ABC is right-angled at C. If AC = 5cm and BC = 12cm find the length of AB
BC= 12cm
AC = 5cm
According to Pythagoras theorem ,
12^2 + 5^2 = AB^2
144+25 =169 ..
so AB^2 = 169
AB=√169 ..
Therefore, AB= 13cm ..

A sector of a circle has an area of 16.75 square inches. The central angle is 120 degrees. Calculate the length of the radius.
please help :)
Answer:
17.14
Step-by-step explanation:
Area of sector= 120/360(πr^2)
16.75^2 = 120π/360 (r^2)
(π/3)16.75^2 = π/3 r^2(π/3)
293.8 = r^2
r= √293.8
r= 17.14

) Which ratios have a unit rate greater than 1? Choose ALL that apply. 9 5 miles : 6 hour 3 (7) 7 miles : hour 4 1 2 miles: 3 hours 8 2 NI 9 1 3) 4 miles : 3- hours 3 1 3 mile : 2- hours 3 8 } mile : 2 miles : 3 hours 5
I got this right, look....
Evidence:
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The ratios that have a unit rate greater than 1 are:
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours
The unit rate of each given ratio.
9/8 miles = 5/6 hours
Multiply 6/5 on both sides.
6/5 x 9/8 miles = 1 hour
54/40 miles = 1 hour
27/20 miles = 1 hour
1.35 miles = 1 hour
4 miles = 3(1/3) hours
4 miles = 10/3 hours
Multiply 3/10 on both sides.
3/10 x 4 miles = 1 hour
6/5 miles = 1 hour
1.2 miles - 1 hour
7 miles = 3/4 hours
Multiply 4/3 on both sides.
4/3 x 7 miles = 1 hour
28/3 miles = 1 hour
9.33 miles = 1 hour
We see that,
All of them have unit rates greater than 1.
Thus,
The ratios that have a unit rate greater than 1 are:
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours
