Answer:

In order to have the answer, 3.487×10^-5, you have to make the power of 10 into -5 :

7×10^-8 = 0.007×10^-5

e.g.

1×10^-2 = 0.01

1×10^-4 = 0.01×10^-2

(take note: when the power is negative, you have to move to the left)

Then you can solve it :

0.007×10^-5 + 3.48×10^-5

= 10^-5(0.007 + 3.48)

= 10^-5(3.487)

= 3.487×10^-5

Answer:

AP is 11.25 so the answer is F

Step-by-step explanation:

Since they are similar triangles (due to the ~ symbol)

You can write this:

AC/XZ = AP/XQ

since XZ=12

XQ=5

AC=27

you can write:

27/12=AP/5

then cross multiply:

27x5=135

135/12=11.25

AP is 11.25

The circumference of a circle is 6 pi cm what is the length of an arc of 140 degree
ValentinkaMS [17]
Since the total circumference of the circle is 60 pi cm which passes around 360˚, the length of an arc of 140˚ will be equal to 140/360 = 7/18 times the total length:
l = (7/18) * 60 pi cm = 23.3 pi cm

spin [16.1K]

Answer:

$9,102

Step-by-step explanation:

Ingrid Sering sells two types of garden fountains on a straight commission basis. On one fountain that sells for $869, she gets a commission of $174. On the other fountain that sells for $1,260, she gets $252.During a 3-month selling season, Ingrid sold 19 of the lower-priced fountains and 23 of the higher-priced fountains. What were her total commissions for three months

From the question above, we have the following information:

On one fountain that sells for $869 = she gets a commission of $174( the lower-priced fountains)

On the other fountain that sells for $1,260 = she gets $252 ( the higher-priced fountains)

Ingrid sold 19 of the lower-priced fountains)

1 fountain sold = $174 of commission

19 fountains sold =

$174 × 19

= $3,306

She also sold 23 of the higher-priced fountains)

1 higher priced fountains = $252

23 higher priced fountains =

$252 × 23

= $5,796

Hence, the Total commission Ingrid made = Total commission on Lower priced fountains + Total commission on Higher priced fountains

= $3,306 + $5,796

= $9,102

Therefore, the total commission Ingrid made = $9,102
