Answer:

π m

Step-by-step explanation:

Arc length = 2πr $\frac{0}{360}$

where r = radius and 0 = central angle

The given radius is 4m and the given central angle is 45°

Thus, arc length = 2π4 $\frac{45}{360}$

* simplify *

( note when simplifying we leave our answer in terms of π as the answer choices do. )

2 * 4 = 8

$8\frac{45}{360} =1$

arc length = 1π

Hence, arc length = 1π or just π

olga55 [171]

Answer:

0.1 cents per ounce

Step-by-step explanation:

You know that you paid 88 cents for the whole bottle of ketchup and the whole body contains 9oz of ketchup. Every one ounce is equal to 9.8 cents. You simply need to divide the total amount of the item by the weight (9 ounces) to get 0.09 or 0.1 when rounded.

$\frac{88 cents}{9oz}=0.1 cents per ounce$

. Caroline had 400 stamps in her collection. 1 10 th of them were Indian stamps, Onethird of the remaining stamps were from Euro

Ganezh [65]

Answer:

So 400 stamps

African---> 100

Indian------> 1/10 x 400

= 40

European---> 400-40=360

1/3 x 360

= 120

so 120+40+100= 260

400-260

= 140 stams from US

The answer is 11 because if you look at the chart. You can see everything can be divided by 8 and 88 divided by 8 is 11.

seropon [69]

Answer : option B

This graph shows the solutions to the inequalities

system of inequalities y>3x+14 and y<3x+2

the system of inequalities have solutions only when the shaded part satisfies the given inequalities

We are given with the graph of inequalities . The given inequalities have 'and' in between.

so we look at the graph where both inequalities intersects

From the graph we can see that there is no intersection part of both shaded portions

So , we conclude that there is no solution.
