TRIGINOMETRY HELP PLS, Q 9-13 with working out

Answer:

t=(a+by)/(y-1)

Step-by-step explanation:

(t-b)y =t+a

ty-by = t+a

ty-by=t+a

ty-by=a+by

t(y-1)=a+by

thus,

t=(a+by)/(y-1)

Answer:

C

Step-by-step explanation:

It is 75 cents a game plus 5 dollars admission. You should automatically subtract 5 dollars for admissions. That would give you ten dollars. You would just multiply how many games by how much they cost.

(You can also find the number of games first, and then solve the two inequalities that match that number backwards)

Hope this helps :)

Answer:

The correct answer is a total of 9 arrangements with a total of 8 balloons in each. 4 mb, 3 wb, 2 ob.  

Step-by-step explanation:

There is a total of 72 balloons just divide by 8.

72/8 = 9

since 32, 24, 16 are divisible by 8 now we can divide and get 9 arrangements.

4 maroon ballons

3 white balloons

2 orange balloons

9 total

Answer:

10°

Step-by-step explanation:

It's a right angle so

90° - 52° = 38°

38 - 8 = 30

30 ÷ 3 = 10

check the work

3 × 10 = 30

30 + 8 = 38

38 + 52 = 90

Answer:

x=2.5

Step-by-step explanation:

2x+3x-4=x+6

5x-4=x+6

4x=10

x=10/4

x=5/2

x=2.5

Answer:

4x=10 or x= 10/4 or x= 5/2 or x= 2 and 1/2 or also E

Step-by-step explanation:

You can combine like terms by adding 2x and 3x, as they have the same variable with no extra additions onto them. You get 5x.

The current equation should look like 5x-4=x+6

Then you can subtract 1x from both sides, to get rid of the x on the right side to get 4x-4=6

Then you can do a similar operation to add 4 on both sides to get 4x=10.

Finally you can divide both sides by 4 (simplifying to get unit rates of x)

You get x = 10/4

You simplify to get 5/2 and it can simplify to a mixed number if needed which is 2 and 1/2

Answer:

1)A.{2,3,5,7,11,13}

2) A.{t| t>4}

Step-by-step explanation:

Choose the correct solution in roster form.

1. S is the set of prime numbers that are less than 15

The Definition of a prime number is given as follows:

A prime number can be defined as the number number that can only be divisible of divided by 1 and itself

Hence the list of prime number below 15 is given as:

2, 3, 5, 7, 11 and 13

Hence, option A.{2,3,5,7,11,13} is correct

2. Write the solution to the inequality in set-builder notation.

9t-4>32

Solving for the given inequality

9t > 32 + 4

9t > 36

t >36/9

t > 4

Therefore, the solution to the inequality in set-builder notation is:

Option A.{t| t>4}

Answer:

f = [tex]\frac{1}{9}[/tex] [C - 4(h - p)] grams

Step-by-step explanation:

Given that:

   C = 4h + 9f + 4p

where: C is the calorie count contained in the serving, h is the number of grams of carbohydrate contained in the​ serving, f is the number of grams of fat contained in the​ serving, and p is the number of grams of protein contained in the serving.

To solve for the number of grams of fat, then;

C - 4h - 4p = 9f

C - 4(h - p) = 9f

Divide through by 9, so that:

[tex]\frac{C - 4(h - p)}{9}[/tex] = [tex]\frac{9f}{9}[/tex]

[tex]\frac{C - 4(h - p)}{9}[/tex] = f

∴     f = [tex]\frac{1}{9}[/tex] [C - 4(h - p)]

The number of grams of fat, f, contained in a serving of food is [tex]\frac{1}{9}[/tex] [C - 4(h - p)]

Answer:

Madelyn bought 2 bags of popcorn and 8 pretzels.

Step-by-step explanation:

Madelyn and her children went into a movie theater and she bought $39 worth of bags of popcorn and pretzels. Each bag of popcorn costs $6.50 and each pretzel costs $3.25. She bought 4 times as many pretzels as bags of popcorn. Graphically solve a system of equations in order to determine the number of bags of popcorn, x,x, and the number of pretzels, y,y, that Madelyn bought.

\underline{\text{Variable Definitions:}}

Variable Definitions:

​  

x=

x=

\,\,\text{the number of bags of popcorn}

the number of bags of popcorn

y=

the number of pretzels

One bag of popcorn costs $6.50, so xx bags of popcorn cost 6.50x.6.50x. One pretzel costs $3.25, so yy pretzels cost 3.25y.3.25y. The total 6.50x+3.25y6.50x+3.25y equals \$39:$39:

6.50x+3.25y=39

6.50x+3.25y=39

Since Madelyn bought 4 times as many pretzels as bags of popcorn, there are more pretzels, so if we multiply 4 by the number of bags of popcorn, we will get the number of pretzels, meaning yy equals 4x.4x.

y=4x

y=4x

The xx variable represents the number of bags of popcorn and the yy variable represents the number of pretzels. Since the lines intersect at the point \left(2, 8\right)(2,8) we can say:

Madelyn bought 2 bags of popcorn and 8 pretzels.

Answer:

c. m∠2 = m∠5

Step-by-step explanation:

We can check 1 by 1 and find the false one.

For answer A, measures 2 and 4 are vertical angles, which means they are equal, so that's not false.

For answer b, measures 4 and 8 are corresponding angles, since X and Y are parallel, so that's also not false.

For answer c, measures 2 and 5 are supplementary to each other, and since the transversal is not perpendicular to X nor Y, they are not equal, therefore, this is false, making that the answer.

For answer d, measure 2 and 6 are corresponding angles, so that's also not false.

Therefore, the answer must be c.
