Answers

Answer 1
Answer: If you would like to solve 12 / 2 + 4 - 2 * 3, you can calculate this using the following steps:

12 / 2 + 4 - 2 * 3 = 6 + 4 - 6 = 4

The correct result would be A. 4.

Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use: Step 1: Choose a point on the line, such as (2, 5). Step 2: Choose another point on the line, such as (1, 3).Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is. Step 4: Substitute those values into the point-slope form. y – y1 = m(x – x1) y – 3 = (x – 1) Which of Talia’s steps is incorrect? Step 1 is incorrect because it uses a point that is not on the line. Step 2 is incorrect because it uses a point that is not on the line. Step 3 is incorrect because it shows an incorrect ratio of the slope. Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form

Which sequence is geometric and has 14 as its fifth term and 12 as the common ratio?

Answers

geometric sequence is
an=a1(r)^(n-1)
an=nth erm
a1=first term
r=common ratio

5th term=14
a5=a1(12)^(5-1)=15

a1(12)^4=15
a1(20736)=15
divide both sides by 20736
a1=15/20736=5/6912
geometric sequence is
an=(5/6912)(12)^(n-1)

Solve the triangle.

B = 72°, b = 12, c = 8

Answers

Answer:

Part 1) C=39.3\°

Part 2) A=68.7\°

Part 3) a=11.8\ units

Step-by-step explanation:

we know that

Applying the law of sines

(a)/(sin(A))=(b)/(sin(B)) =(c)/(sin(C))

In this problem we have

B=72\°

b=12\ units

c=8\ units

Step 1

Find the measure angle C

(b)/(sin(B)) =(c)/(sin(C))

substitute the values and solve for C

(12)/(sin(72\°)) =(8)/(sin(C))\n \nsin(C)=sin(72\°)*(8/12)\n \nsin(C)= 0.6340\n \nC=39.3\°

Step 2

Find the measure of angle A

we know that

The sum of the internal angles of the triangle must be equal to 180 degrees

so

m<A+m<B+m<C=180\°

we have

m<B=72\°

m<C=39.3\°

m<A+72\°+39.3\°=180\°

m<A=180\°-72\°-39.3\°=68.7\°

Step 3

Find the measure of side a

Applying the law of cosines

a^(2)=b^(2)+c^(2)-2(b)(c)cos(A)

substitute

a^(2)=12^(2)+8^(2)-2(12)(8)cos(68.7\°)

a^(2)=208-(192)cos(68.7\°)

a^(2)=138.26

a=11.8\ units
The answer is 12^2=x^2+8^2-16x(cos(72°) 
x^2-4.9443x=80 
(x-2.4721)^2=86.1115 
x-2.4721=±9.2796 
x=11.7517 

B=72°, b=12, c=8, a=11.8 
C=arcsin(8/12*sin(72°))=39.3° 
A=68.7°

baseball card come in packs of a dozen 12 cards matt has 132 baseballcards.how many packs of baseball cards did he buy i need help in proportion

Answers

Well let's see first we have to divide
132 divided by 12 is 11
Now to check and prove your answer we should use the multiplication.
11 times 12 is 132.
So now you have a solid answer with proof behind it.
If u need a sentence you might want it to go something like this;
Matt brought 11 packs of baseball cards since 132 divided by 12 is 11. 12 times 11 is 132 cards.
Hope I helped!

Answer:

11

Step-by-step explanation:

you will need to divide 132 by 12. and you will get 11. Bam that simple hope you have a great day! :)
