Write and solve an equation to answer the question. 14 is what percent of 70?

slamgirl [31]

Answer:

20%

Step-by-step explanation:

An equation is 14=x/100*70 or 14=(x%)*70, either one works

solve for x:

14=x/100*70
14/70=x/100 (Divide each side by 70)
1/5=x/100 (Simplify 14/70)
100/5=x (Multiply each side by 100 to isolate x)
x=20 (Simplify 100/5)
20% (Rewrite as a percent)

hope this helps!!

Drag a reason to each box to complete the proof. Please help will give you brainliest

Helga [31]

Answer:

The required proof is shown below.

Step-by-step explanation:

Consider the provided figure.

It is given that KM=LN

We need to prove KL=MN

Now consider the provided statement.

KM = LN Given

KM = KL+LM Segment addition postulate

LN = LM+MN Segment addition postulate

KL+LM = LM+MN Substitution property of equality

KL = MN Subtraction property of equality

The required proof is shown above.

10. Make Sense and Persevere The flag of the

kumpel [21]

Answer:

$s=\frac{P}{3}$
Dimensions of the flag:

$lenght=6.65\ ft\\\\width=3.5\ ft$

Area of the flag: $23.275\ ft^2$

Step-by-step explanation:

The missing figure of the exercise is attached.

We know that the perimeter of the triangle is given by:

$P= 3s$

Where "s" is the side lenght of the triangle.

Solving for "s", we get:

$s=\frac{P}{3}$

Therefore, if the perimeter of the triangle is 126 inches, its side length is:

$s=\frac{126\ in}{3}\\\\s=42\ in$

Since $1\ ft=12\ in$ , we know that "s" in feet is:

$s=(42\ in)(\frac{1\ ft}{12\ in})=3.5\ ft$

The area of a rectangle can be calculated with this formula:

$A=lw$

Where "l" is the lenght and "w" is the width

We can observe in the figure that the lenght and the width of the flag are:

$l=1.9s\\w=s$

Then, the dimensions of the flag are:

$l=1.9(3.5\ ft)=6.65\ ft\\w=3.5\ ft$

And the area is:

$A=(6.65\ ft)(3.5\ ft)=23.275\ ft^2$
