Lynn bought a bag of grapefruit 1 5/8 pounds of apples to + 3/16 pounds of bananas the total weight of her purchase with 7 1/2 pounds how much did the bag of grapefruit way

Answers

Let us assume the weight of grapefruit = x pounds
Weight of the apples = 1 5/8 pounds
                                   = 13/8 pounds
Weight of the bananas = 3/16 pounds
The total weight of her purchase = 7 1/2 pounds
                                                     = 15/2 pounds
Then we get the equation as
x + 13/8 + 3/16 = 15/2
16x + 26 + 3 = 16 * (15/2)
16x + 29 = 8 * 15
16x + 29 = 120
16x = 120 - 29
16x = 91
x = 91/16
So the weight of the grapefruit is 91/16 pounds. It can also be written
as 5 11/16 pounds

If arc AD = 130° and arc AB = arc CD = 80°, what is the measure of ∠APD?

Answers

Answer:

(B)

Step-by-step explanation:

Given: It is given that arc AD=130° and arc AB=arc CD=80°.

To find: The measure of ∠APD.

Solution: It is given that arc AD=130°⇒m∠AOD=130° (The measure of the central angel is equal to the intercepted arc)

Also, arc AB=arc CD=80°⇒m∠AOB=m∠DOC=80° (The measure of the central angel is equal to the intercepted arc)

We know that the sum  of the central angles is equal to 360°, thus

m∠AOD+m∠AOB+m∠BOC+m∠COD=360°

⇒130°+80°+m∠BOC+80°=360°

⇒290°+m∠BOC=360°

⇒m∠BOC=360°-290°

⇒m∠BOC=70°

Now, since  (The measure of the central angel is equal to the intercepted arc), therefore arcBC=70°.

Also, we know that Angle Formed by Two Secants is half of the DIFFERENCE of Intercepted Arcs, therefore

m{\angle}APD=(1)/(2) (arcAD-arBC)

Substituting the values, we get

m{\angle}APD=(1)/(2) (130-70)

⇒m{\angle}APD=(60)/(2)

⇒m{\angle}APD=30^(\circ)

Thus, the measure of ∠APD is 30°.

Hence, option B is correct.

Answer:

the answer is 25

Step-by-step explanation:

1/2(130-80)

What is the answer for 16% of 150

Answers

In order to find a percent of a certain number, you just have to multiply the percentage times the number you are finding the percentage of.
To do this, we must first convert the percentage into a decimal. We can do this by either dividing the percentage by 100, or (my personal shortcut) just shifting the decimal point over 2 places to the left.

16% = 0.16

Now, we multiply

0.16 * 150 = 24

16% of 150 is 24.
Hope that helped! =)
its 24 hope it helps
