20%+9%+8%=37% so 189.99*37/100=70.3$ so 189.99-70.3=119.7$

The chorus at an elementary school is made up on fifth and sixth graders. This year, the chorus had 12 fifth-grade girls, 9 fift
klemol [59]

Answer:

A: 19:26 B:7:8 C:26:45

Step-by-step explanation:

<u>Question A</u>

First to find the ratio between the boys and girls you would add all of the different groups with boys and girls. This would be done by,

<u>Boys</u>

9+10=19

<u>Girls</u>

12+14=26

Now that you have the total number of boys and girls you make this ratio,

19:26

That is the final answer

<u>Question B</u>

For this it is very similar to the boys to girls ratio. You still add the total on each side and then form a ratio. From before you would start by adding both of the different sides which would be done by,

<u>Fifth Graders</u>

12+9=21

<u>Sixth Graders</u>

14+10=24

Now that you have the total number of both of the different grades you make this ratio,

21:24

You can simplify this by finding the lowest common factor which would be

7:8

<u>Question C</u>

To answer this it is very similar to the first two but instead you will find one group and all of the groups to form the ratio. Now you need to add all of the people in each of the groups.

<u>Girls</u>

12+14=26

<u>All</u>

12+9+14+10=45

Now with the total number of both you will form a ratio

26:45

This is your final answer because you cant simplify this any further

PLZ HELP ASAP TANGENTS OF CIRCLES
bezimeni [28]
First, we are given that the inscribed angle of arc CB which is angle D is equal to 65°. This is half of the measure of the arc which is equal to the measure of the central angle, ∠O. 
 
    m∠O = 2 (65°) = 130°

Also, the measure of the angles where the tangent lines and the radii meet are equal to 90°. The sum of the measures of the angle of a quadrilateral ACOB is equal to 360°. 

     m∠O + m∠C + m∠B + m∠A = 360°

Substituting the known values,
     130° + 90° + 90° + m∠A = 360°

The value of m∠A is equal to 50°.

<em>Answer: 50°</em>

Mark bought gifts for his friends, and each gift cost $9. Let y represent the total cost and x represent the number of gifts. Wr
olga nikolaevna [1]

Answer:

y = 9x

Step-by-step explanation:

You can set up linear equations like this: y = mx + b, where m is the slope or rate, and b is the y-intercept.

9 would be the slope, since he has to pay $9 per gift.

The y-intercept is when x = 0, but if he doesn't buy any gifts, he won't have to pay anything, so b = 0. You don't have to include it since it's 0.

So, it's just y = 9x

Hope that helps! :D
