An angle is equal to one-third of its complement. Find the angle's measure.

artcher [175]

Let $x^\circ$ be the measure of the angle in question. Its complement has measure $(90-x)^\circ$ . We're told that this angle is congruent to 1/3 of its complement, so that

$x^\circ=\dfrac{(90-x)^\circ}3\implies3x^\circ=(90-x)^\circ\implies4x^\circ=90^\circ\implies x=22.5^\circ$

Vinnie drives his car 210 miles and has an average of a certain speed. If the average speed had been 3mph more, he could have tr

Pachacha [2.7K]

Answer:

35 mph

Step-by-step explanation:

time = distance / speed

210 miles and has an average of a certain speed

t = 210 / s

If the average speed had been 3mph more, he could have traveled 228 miles in the same length of time

t = 228 / (s + 3)

Set equal

210 / s = 228 / (s + 3)

Cross multiply

210s + 630 = 228s

Subtract 210s from both sides

630 = 18s

Divie both sides by 18

35 = s

35 mph

The table shows the number of students in a class who play on a school team and/or are members of a school club:

eimsori [14]

This one is very simple.

create a simple equation to find out

15 = 12 + x

subtract 12 from each side

x= 3

the missing number is 3

or, to be even simpler, take the total, subtract the total from the number you know and the difference is the missing number.

hope I helped

ALSO, we can check going down vertically. 3 + 10 =13. this is the total listed at the bottom.

Micah needs $18,500 to purchase a boat. How much money will he need to invest today in a savings account earning 3.2% interest,

charle [14.2K]

We have that every quarter, he will get an 0.8% interest rate. We also have that there will be 14*4=56 periods of repayment. We have that by the formula, if there are n periods and x% is the interest rate, the capital is multiplied by (100+x%)^n.
Suppose Micah invests x money. Then, we have that after 14 years, the capital available will be C= $x*(1.008)^{56}=x*1.562$ . We have that C=18500$ and hence that 18500=x*1.562. Thus, solving for x we have that x=11841$.
Micah will need to invest only 11841$ in order to pay for his boat; this shows the importance of saving since he earns a lot of money, around 7k $.
