topjm [15]

Answer:

946

Step-by-step explanation:

we know that

The formula to find the sum is equal to

S=(a1+an)n/2

where

a1 is the first term

an is the last term

n is the number of terms

In this problem we have

n=11

a1=(98-2(1))=96

an=(98-2(11))=76

substitute the values in the formula

S=(96+76)(11/2)=946

* 4. A circle is divided into ten equal sectors.
Fiesta28 [93]

Answer:

a. Find the measure of each central angle.

The central angle of a circle = 360 °

Now Pie is cut into 10 equal sectors

Angle of each sector is given by

Angle of sector = Total central angle/number of sectors

=  {360}^{0}  \div 10

=  {36}^{0}

Hence , the central angle of one slice of pie is 36°

b. If the diameter is 50 in., find the length of an arc of one of the sectors.

length of an arc of one of the sectors =

= \frac{1}{n}  \times 2\pi \times r

= \frac{1}{10}  \times 2\ \frac{22}{7}  \times 50

= 31.42 \: in

 Jamal works at a sporting goods store on the weekends. Suppose last weekend he worked
rusak2 [61]

Answer:

$8.8 per hour

Step-by-step explanation:

Well, the equation is simple.

Time (hours) * Money (per hour) = Total

We know the time he worked for and the total amount he earned, so just replace in this equation and find the unknown number

12.5 * money = 110

To find the money he earns per hour we should just simply divide the total amount he earned by the hours he spent working

money = 110/12.5

money = 8.8$

You can also check it out to make sure it's correct.

If he earns 8.8$ per hour and worked for 12.5 hours how much he'll earn? Let's find out

8.8 * 12.5 =?

8.8 * 12.5 = 110, the same total amount so our solution must be correct.
