Answer:

m=60º

n=30º

Step-by-step explanation:

a triangle is 180º total

an equilateral triangle has all 60º angles

since the one symbol for a right angle is cut between two triangles you can say that the one angle in the equilateral triangle +n=90º

substituting the values 60+n=90

so n=30

Then since a triangle is 180º you can make an equation that says 180=90+m+n

again substituting 180=90+m+30

60=m

an easy way to check is 180=90+30+60 180=180

The number of girls in the Middle School Cyber Club was 6 more than double the number of boys, and in total there were 48 middle

Wittaler [7]

Answer:

g = number of girls;

b= number of boys

we know that: g= 6+2b

and that: g+b= 156 kids in total

so we may write g+b=(6+2b)+b=6+3b

but g+b= 156

so 6+3b = 156 => 3b= 156-6=150 => b=150/3=50 => b = 50 (number of boys)

g= 6+2b= 6+2 x 50= 106 => g =106 (number of girls)

Identify the k-value that makes the relationship shown in the table below proportional.

uysha [10]

Answer:

The value of k that makes the relationship shown in the table below proportional is $\mathbf{\frac{1}{2}}$

Step-by-step explanation:

The relation is proportional if $y=kx \:or\:k=\frac{y}{x}$

Putting values of x and y to find k.

For x =2 and y =1 k is: $k=\frac{y}{x}=\frac{1}{2}$

For x =4 and y =2 k is: $k=\frac{y}{x}=\frac{2}{4} =\frac{1}{2}$

For x =6 and y = 3 k is: $k=\frac{y}{x}=\frac{3}{6} =\frac{1}{2}$

For x = 8 and y = 4 k is: $k=\frac{y}{x}=\frac{4}{8} =\frac{1}{2}$

For x =10 and y = 5 k is: $k=\frac{y}{x}=\frac{5}{10} =\frac{1}{2}$

So, The value of k that makes the relationship shown in the table below proportional is $\mathbf{\frac{1}{2}}$

What is longer 180 seconds or 3 minutes

Neporo4naja [7]

They are both the same. There are 60 seconds in one minute, so 60*3 is 180. Since 180=180, they are equal.
