Answer:

x = 40°

y = 65°

n = 65°

Step-by-step explanation:

70 + 70 = 140

180 - 140 = 40

55 + 60 = 115

180 - 115 = 65

180 - 50 = 130

130 / 2 = 65

On Monday, Mr. Roberts drove 42 miles. On Tuesday, he drove 5 miles more than half the distance he drove on Monday. Which expres

butalik [34]

Answer: Last option

(42÷2) +5

Step-by-step explanation:

We know that Mr. Roberts drove 42 miles on Monday.

On Tuesday Mr. Roberts drove half of what he drove on Monday plus 5 miles.

If we want to know how many miles Mr. Roberts drove on Tuesday then we should divide 42÷2 to find half of 42.

$\frac{42}{2} = 21$

Then we know that in addition to the 21 miles he drove 5 more miles. Then we add 21 +5 = 26 miles.

So the expression that gives us the number of miles that Mr. Roberts drove on Tuesday is:

(42÷2) +5

Diego was trying to write 2^3 · 2^2 with a single exponent and wrote 2^3·2^2 = 2^3*2 = 2^6 . Explain to Diego what his mistake w

cupoosta [38]

Answer:

2^3·2^2 = 2^3+2 = 2^5

Step-by-step explanation:

Diego was trying to write 2^3 · 2^2

He wrote 2^3·2^2 = 2^3*2 = 2^6

But this is wrong because when bases are same exponents are added.

This is the law of exponents.

The correct form would be

2^3·2^2 = 2^3+2 = 2^5

For understanding it better we can write it like this

2^3·2^2 =

There are 3 two and 2 twos .When totaled there are 5 two not 6 twos.

if we have a geometric series with u1 = 2.1 and r= 1.06, what would the least value of n be such that Sn > 5543?

bulgar [2K]

Answer:

Step-by-step explanation:

Write the expression for the sum in the relation you want.

Sn = u1(r^n -1)/(r -1) = 2.1(1.06^n -1)/(1.06 -1)

Sn = (2.1/0.06)(1.06^n -1) = 35(1.06^n -1)

The relation we want is ...

Sn > 5543

35(1.06^n -1) > 5543 . . . . substitute for Sn

1.06^n -1 > 5543/35 . . . . divide by 35

1.06^n > 5578/35 . . . . . . add 1

n·log(1.06) > log(5578/35) . . . take the log

n > 87.03 . . . . . . . . . . . . . . divide by the coefficient of n

The least value of n such that Sn > 5543 is 88.
