Answer:

231

Step-by-step explanation:

Given

\frac{4}{77}=\frac{12}{x}

Cross Multiply

x \times 4=12\times 77\\x=\frac{12\times 77}{4} \\x= 3\times 77\\x= 231

Therefore x=231

Gulf gully and jump rope road are a pretty far distance.If the scale for the map is 0.5 inches=2.3 miles,what is the actual dist
Nezavi [6.7K]

Answer:

12 cm = 21.62 miles

6 cm = 11.04 miles

Step-by-step explanation:

To find the distance, set up a proportion. A proportion is two equal ratios set equal to each other. We form the ratios by using corresponding values. We write a ratio of \frac{map}{real world} and simplify.

We know \frac{map}{real world}=\frac{0.5in}{2.3 miles}. We know the distance on the map is 12 cm and 6 cm whish converts to 4.7 inches and 2.4 inches. We can write \frac{4.7in}{xmiles} and  \frac{2.4in}{xmiles}

We set them equal.

\frac{0.5}{2.3}=\frac{4.7}{x}

and

\frac{0.5}{2.3}=\frac{2.4}{x}

To solve each proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

2.3(4.7)=0.5(x)\\10.81=0.5x\\\frac{10.81}{0.5}=\frac{0.5x}{0.5} \\21.62 miles=x

and

2.3(2.4)=0.5(x)\\5.52=0.5x\\\frac{5.52}{0.5}=\frac{0.5x}{0.5} \\11.04 miles=x

Write the equation of a line with a slope of 5 and contains the point (-6, 2)
tigry1 [53]
I think the answer would be y=5x-3/5. You would use the point slope formula(y=mx+b) and plug in 5 for m and the x and y of the point for x and y. Solve for b and the plug in b and 5 into the point slope formula to get the answer! Hope it helps!!

-12<-6x please help
pishuonlain [190]
-12 < -6x

-12/-6 > x    divide both sides by -6

12/6 > x      two negatives makes a positive

2 > x            simplify

x < 2           
switch sides

hope this helps, God bless!

Which expression is equivalent to the given expression? 2√20 × 4√6
lapo4ka [179]

Answer:

16 sqrt(30)

Step-by-step explanation:

2√20 × 4√6

Multiply

2*4  sqrt(20*6)

8 sqrt(120)

Simplifying

8 sqrt(4 *30)

We know sqrt(ab) = sqrt(a) sqrt(b)

8 sqrt(4) sqrt(30)

8 *2* sqrt(30)

16 sqrt(30)
