Use this theorem: in a circle, the measure of an angle formed by two chords that intersect inside the circle is half the sum of the arcs formed by the chords.

In this case the sum of the arcs formed by the chords is 67° + 74° = 141 °, then the half is 141° / 2 = 70.5°.

Answer: 70.5°

.John has $40. He will use some of the money to buy books, and he wants to have at least $10 left to put in his savings account.

Crank

Answer:

The required inequality is $40-6b\leq 10$ .

Jhon can buy at most 5 books.

Step-by-step explanation:

Consider the provided information.

Part(A)

Let b represent the number of books John buys.

He wants at least $10 in his savings account which means if we subtract the cost of books from $40 we have at least $10 left.

$40-6b\leq 10$

The required inequality is $40-6b\leq 10$ .

Part(B)

$40-6b\leq 10$

$-6b\leq 10-40$

$b \leq\frac{30}{6}$

$b\leq 5$

Part(C): Jhon can buy at most 5 books.

Stefan sells Jin a bicycle for $147 and a helmet for $18. The total cost for Jim is 150% of what Stefan spent originally to buy

soldi70 [24.7K]

Answer:

He spent $110.00 on both originally

Step-by-step explanation:

Add both prices too get 165

Then use the equation $\frac{150}{100}$ = $\frac{165}{x}$

cross multiply to get 150x=16500

Divide 16500 by 150 to get x alone

x= 110
