The equation we can use to find the value of x in the diagram given is: B. (5x + 30) + 5x = 90.

Angles that give a sum of 90 degrees when added are referred to as complementary angles.

The angles, (5x + 30) and 5x are complementary angles, since the sum of both gives a right angle (90 degrees).

Therefore, the equation that we can use to find x in the diagram is: B. (5x + 30) + 5x = 90.

To isolate x , multiply both the sides by   ( 5/23 )

An equation is formed when two algebraic expressions are equated using an equal sign.

The given equation is

(3/5)(x-10) = 18-4x-1

(3/5)x - 6 = 18-4x-1

(3/5)x - 6 = 17-4x

Factorization of sin²θ + sin²θ cos²θ gives us; 2sin²θ - sin⁴θ

We want to simplify;

Let us factorize out sin²θ to get;

sin²θ(1 + cos²θ)

Now, we know that cos²θ = 1 - sin²θ

Thus;

sin²θ(1 + cos²θ) = sin²θ(1 + 1 - sin²θ)

Answer:

22 8th graders

Step-by-step explanation:

if 25% of the 88 kids are 8th graders then do this.

88x.25=22

88x.75=66

there are 22 eighth graders

and 66 seventh graders.

The amount of time that Lila spent at Yoga and Ballet are approximately equal to 26 hours and 13 hours respectively.

First of all, we would calculate the amount of time that Lila spent at Yoga by multiplying the total time spent by the percentage of time spent on Yoga as follows:

Yoga time = 92 × 28/100

Yoga time = 92 × 0.28

Yoga time = 25.76 ≈ 26 hours.

Next, we would calculate the amount of time that Lila spent at Ballet by multiplying the total time spent by the percentage of time spent on Ballet as follows:

Ballet time = 92 × 14/100

Ballet time = 92 × 0.14

Ballet time = 12.88 ≈ 13 hours.

(a)

the sum of the 3 angles in the triangle = 180° , then

∠ A = 180° - 90° - 48° = 180° - 138° = 42°

(b)

using the tangent ratio in the right triangle

tan48° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{y}{10}[/tex] ( multiply both sides by 10 )

10 × tan48° = y , then

y ≈ 11.1 units ( to the nearest tenth )

(c)

using the cosine ratio in the right triangle

cos48° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{10}{x}[/tex] ( multiply both sides by x )

x × cos48° = 10 ( divide both sides by cos48° )

x = [tex]\frac{10}{cos48}[/tex] ≈ 14.9 units ( to the nearest tenth )

Answer:

B. g(x) = 3/4|x|

Step-by-step explanation:

Multiplying the function by a number in front will stretch, compress, and/or reflect the function over the x-axis.

So if the number in front is negative that will flip it upside down, over the x-axis.

If the number is greater than 1, the function will be vertically stretched, narrower, slimmer, skinnier, taller.

In this case, the graph is vertically compressed, making it flatter, fatter, wider smashed. In this case is where the number multiplied in front of the parent function is LESS than one.

Andy's equation is incorrect and the correct equation of the line is y + 2= 3/4(x - 3)

The given parameters are:

Slope, m = 3/4

Point, (x,y) = (3,-2)

The equation of the line is calculated using:

y - y1 = m(x - x1)

Substitute the known parameters

y + 2= 3/4(x - 3)

From the question;

Andy's equation is y + 2 = 3/4(x - 9/4)

The above equation is different from the actual equation y + 2= 3/4(x - 3)

Step-by-step explanation:

First divide the 400 toys by the 5 people to see how many each did:

400 toys/5 people = 80 toys/person

Next let's see how many hours were worked by multiplying the hours per day by the number of days worked:

5 days x 8 hours/day

40 hours

Now to find how many toys were assembled per hour per person, let's divide the toys/person by the number of hours they each worked:

[tex]\frac{80 toys/person}{40 hours}[/tex]=2 toys/person/hour

The average number of toys per person per hour is 2.

Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

Total number of toys assembled = 400

Total days of work = 5  

Each person work daily for = 8 hrs

Total number of people = 5

Then, the total toys assembled per day

400/5= 80

The number of hours worked by the 5 workers per day = 8 × 5= 40

So, the number of toys assembled per person per hour = 80 / 40= 2

Hence, the average number of toys per person per hour is 2.

There 1,32,600 possibilities to withdrawn 3 different sequence of playing cards from 52 cards.

A permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements.

Here, total number of cards = 52

         Number of Withdrawn cards = 3

Possibilities of different sequences of 3 playing cards = 52 X 51 X 50

                                                                                          = 132600

Answer:

132,600

Step-by-step explanation:

To determine the number of different sequences of 3 playing cards from a 52-card deck, we can use the formula for permutations, which is given by:

P(n, k) = n! / (n-k)!

Where n is the total number of items (in this case, the number of cards in the deck) and k is the number of items chosen (in this case, 3 cards).

Plugging in the values:

n = 52 (total number of cards in the deck)

k = 3 (number of cards chosen)

P(52, 3) = 52! / (52-3)!

Calculating the factorial terms:

52! = 52 x 51 x 50 x ... x 3 x 2 x 1

(52-3)! = 49! = 49 x 48 x ... x 3 x 2 x 1

Simplifying the equation:

P(52, 3) = 52 x 51 x 50

P(52, 3) = 132,600

Therefore, there are 132,600 different sequences of 3 playing cards that can be formed from a single 52-card deck.

plug in y into one of the equations

4x + 3 = 19

4x=16

If not, I am sorry.

Answer:

(4, 3 )

Step-by-step explanation:

4x - 2y = 10 → (1)

4x + y = 19 → (2)

subtract (1) from (2) term by term

(4x - 4x) +y - (- 2y) = 19 - 10

0 + y + 2y = 9

3y = 9 ( divide both sides by 3 )

y = 3

substitute y = 3 into either of the 2 equations and solve for x

substituting into (2)

4x + 3 = 19 ( subtract 3 from both sides )

4x = 16 ( divide both sides by 4 )

x = 4

solution is (4, 3 )
