Otrada [13]

Turn a percent into a decimal by moving the decimal point two to the left.

10 x 6% = 10 x .06

10 x .06 = .60

Sales tax: 60 cents

Total price: $10.60

Given ab and cb are tangents of p, and m =10°. What is the measure of abp?
yanalaym [24]

Answer:

Hence, ∠ABP=10°

Step-by-step explanation:

We are given that:

AB and CD are tangents of the circle.

Now we are given that m∠ACP=10°.

Also we are given that AP and CP are radius of the given circle that means length of AP and CP are equal.

Also we know that angle opposite to the equal sides are equal that means:

∠ACP=∠PAC.

Hence , ∠PAC=10°.

Also in a triangle the sum of all the angles is 180°.

i.e. ∠ACP+∠PAC+∠APC=180°

this means that 10+10+∠APC=180°

∠APC=180-20

∠APC=180-20=160°

As AB and CD are tangents to the circles that means:

∠BAP=∠BCP=90°

Also APCB is a quadrilateral and we know that sum of all the angles of a quadrilateral=360°

Hence,

∠BAP+∠BCP+∠APC+∠ABC=360°

⇒ 90+90+160+∠ABC=360

⇒ 180+160+∠ABC=360

⇒ 340+∠ABC=360

⇒ ∠ABC=360-340=20°

also ∠ABP=(1/2)∠ABC

Hence, ∠ABP=(1/2)×20°=10°

Hence, ∠ABP=10°

Can someone please give me the answers to all three I will be marking u brilliant
Sedbober [7]

Answer:

1. 18

2. 49.5

3. 48

Step-by-step explanation:

1. Since it is 3 dogs to 1 person we need to multiply 6 with 3, so we get 18 dogs!

2. Since 2 books equal 8.25, we just need to multiply 8.25 by 6, which we get 49.5 from!

Hope this helps and don't forget to follow!

Solve this Expression below : W -1/4 = 3 /7 .So that the Question is to Solve for W. ​
mezya [45]

W-1/4= 3/7

W-1/4+1/4= 3/7+1/4

find the common denominator for the fractions

common denominator is 28

Multiply by 4 , top and bottom for 3/7

Multiply by 7 , top and bottom for 1/4

W= 12/28+7/28

W= 19/28

Answer is W= 19/28

=0.56x−0.25n=0.20x−0.03
katovenus [111]

Given:

m=0.56x-0.25

n=0.20x-0.03

To find:

The sum of m and n.

Solution:

We have,

m=0.56x-0.25

n=0.20x-0.03

The sum of m and n is:

m+n=(0.56x-0.25)+(0.20x-0.03)

Combining the like terms, we get

m+n=(0.56x+0.20x)+(-0.25-0.03)

m+n=(0.76x)+(-0.28)

m+n=0.76x-0.28

Therefore, the sum of m and n is m+n=0.76x-0.28.
