<u>Answer:</u>
<u>Step-by-step </u><u>Explanation</u><u>:</u>
The sequence is following some rule. And the rule is: Multiplying the term with 4 to get the next term. Like:
Similarly, the next terms are:
The terms are <u>6</u><u>4</u><u>,</u><u> </u><u>2</u><u>5</u><u>6</u><u>,</u><u> </u><u>1</u><u>0</u><u>2</u><u>4</u> which matches with Option D. And that's the correct answer
A suitable proportion would be:
1 x
----- = ------------
50 230 ft
Cross-multiplying, 230 ft = 50 x. Then x = 4.6 ft. That's a big model, but still this answer is reasonable.
X=mumber of boys
y=number of girls.
I suggest this system of equations:
x+y=30
x=4y
We can solve this system of equations by susbtitution method.
4y+y=30
5y=30
y=30/5=6
x=4y
x=4*6=24
Answer: there are 6 girls
Answer:
Yes, they are equivalent
Step-by-step explanation:
Case 1,
Distance = 250 miles
Time = 4 hours
Ratio = speed = distance/time
= 250 miles/4 hour
= 62.5 mph
Case 2,
Distance = 500 miles
Time = 8 hours
Ratio = speed = distance/time
= 500 miles/8 hour
= 62.5 mph
In both cases, the ratios 250 miles in 4 hours and 500 miles in 8 hours are equivalent.
