Molly bought 4 band shirts and 3 pair of pants for 159.99 Christian bought 3 band shirts and 2 pair of pants for 113.00. How much is 5 band shirts and 5 pair of pants

Answer:

AngleCAB = 44°

AngleHAB = 66°

Step-by-step explanation:

AngleEAF is a right angle, equal to 90°.

EH and DC are just two intersecting lines. They form a couple of pairs of vertical angles. Vertical angles are equal to each other. We'll use the vertical angles, AngleEAD and CAH.

Angle EAD and CAH are equal to each other.

EAD = CAH

90°+20° = 2x + 3x

Combine like terms.

110° = 5x

Divide by 5

110/5 = x

22 = x

Angle CAB

= 2x

= 2(22)

= 44

AngleCAB = 44°

AngleHAB

= 3x

= 3(22)

= 66

AngleHAB = 66°

The linear functions will have same or equivalent equations in order to have infinitely many solutions.

Convert the given to slope-intercept form, y = mx + b, to make it equivalent:

Answer:

the portion of the x-axis that the straight line cuts is the interval [5r, -5r].

Step-by-step explanation:

To find the portion of the x-axis that the straight line cuts, we first need to solve the equation for θ. The sine function has a range of [-1, 1], so the value of r must be greater than or equal to 5 in order for the equation to have a solution.

To solve the equation, we can use the fact that sin(π/4 - θ) = cos(θ). Therefore, the equation can be rewritten as:

cos(θ) = 5

We can then use the fact that cos(θ) = x/r to solve for x:

x = 5r

Therefore, the portion of the x-axis that the straight line cuts is the interval [5r, -5r].

Note that this is only valid if r is greater than or equal to 5. If r is less than 5, there are no solutions to the equation and the straight line does not cut the x-axis.

As per the given data, the correlation is 0.7.

Correlation:

in statistics, correlation refers the  association between two quantitative variables.

Given,

Here we have the table of data and now we need to find the correlation of the data.

As per the given data we have calculated the value of r as,

X Values

∑ = 132.38

Mean = 5.295

∑(X - Mx)² = SSₓ = 9.005

And the Y Values

∑ = 170.76

Mean = 6.83

∑(Y - My)² = SSₙ = 26.357

When the X and Y Combined

N = 25

∑(X - Mx)(Y - My) = 10.065

So, the R Calculation

r = ∑((X - My)(Y - Mx)) / √((SSₓ)(SSₙ))

r = 10.065 / √((9.005)(26.357)) = 0.6533

Then the Meta Numeric (cross-check)

r = 0.6533

When we round of these value then we get the value of the correlation as 0.7.

At 9 AM Bob could declare the pool was full of water, using given information about fill rate, discharge rate and time.

What is fill rate and discharge rate ?

The definition of fill rate is the percentage of customers orders you are able to meet without running out of stock at any given time.

The discharge rate is the amount of fluid that is passing through a given cross sectional area per unit time.

We need to divide it in 3 parts:

Part 1: When only 1 hose is filling the pool at 3 gal per hr.

Part 2 : When after 10 hours animals started drinking water .

Part 3: When 2nd hose also started at the rate 2 gal per hr.

Part 1:

For 10 hours it get started . So, pool get filled is 30gal.

Part 2:

After 10 hours, rate decreased by animals at 1 gal/hour.

So, rate = 3-1 = 2 gal/hour.

So, water filled for 5 hour = 10 gal.

So, total pool is filled = 10 + 30 = 40 gal.

Remaining = 60 - 40 = 20 gal.

Part 3:

2nd hose is added at the rate 2gal/hour.

Now, rate = 2+2 = 4 gal/hour.

Time taken for 20 gal = 5 hours.

So, total time taken = 10 + 5 +5

                                 = 20 hours.

We need to find the time ,

Time at which water is started = 1pm

1PM + 11hours = 12AM

For remaining , 9 hours

12AM + 9hours = 9AM.

Represent the cost of each shirt with n

So, we have the following equation

Total cost = Number of shirts * Cost of each shirt + Tax

Substitute the known values in the above equation, so, we have the following representation

Total cost = 7 * n + 6

Acute triangle.

In geomentry, acute triangle is the type of triangle in which all the three internal angles of the triangle are acute

Given,

Here we need to prove that in the acute triangle ABC, the circumcenter of the triangle MNH lies on the line OH.

Let us consider T be the intersection of σ1 and σ1 other than W.

Now, the Lemma 1: T is on XY.

Now, the Proof is written as We have ∠XTW} = ∠YTW = 90 degres because they intercept semicircles.

Therefore, ∠XTY = ∠XTW + ∠YTW = 180 degrees,

Then XTY is a straight line.

Here we know that NHLB is cyclic because ∠BNH and ∠BLH, opposite and right angles, sum to 180 degree. Furthermore, we are given that NTWB is cyclic.

Therefore, the triangle MNH lies on the line OH.

If the probability that the bug moves to its starting vertex on its tenth move is m/n , then the value of m+n is 683 .

In the question ,

it is given that ,

the bug starts from a vertex of an equilateral triangle , and

in each move , it randomly selects one of  two vertices where it is not currently located .

Let the probability that the bug is at its starting vertex after n moves is Pₙ .

If the bug is on its starting vertex after n moves, then it must be not on its starting vertex after n-1 moves .

At this point it will has (1/2) chance of reaching starting vertex in the next move.

Thus Pₙ =  (1/2)(1 - Pₙ₋₁) . P₀ =1 ,

So , the probabilities in each move can be written as

P₁ = 0 ,  P₂ = 1/2, P₃ = 1/4 , P₄ = 3/8 , P₅ = 5/16, P₆ = 11/32 , P₇ = 21/64 , P₈ = 43/128, P₉ = 85/256, P₁₀ = 171/512 ,

The sample standard deviations of the data set 2, 3, 5, 6, 7 rounded up to 2 decimal spaces is 2.07.

The term "standard deviation"  refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. Think about the following data: 2, 1, 3, 2, 4.

The amount of time needed for an isotope's radioactivity to decrease to 50% of its initial value.

The given data is

T1/2=5.25 days.

No=25g

T=11 days

We'll have to find the disintegration constant first.

The formula for finding it is

T½ = In2 / λ

T½ = half-life

λ = disintegration constant

λ = In2 / T½

λ = 0.693 / 5.25

λ = 0.132

In(N / No) = -λt

where,

N = final mass of the radioactive sample

No = initial mass of the sample

λ = disintegration constant

t = time for the radioactive decay

In(N/No) = -λt

N / No = e^-λt

N = No(e^-λt)

N = 25 × e^-(0.132 × 11)

N=5.8525 g.

Given,

Here we have the three long wires hang vertically. The distance between wire 1 and wire 2 is 23.0 cm On the left, wire 1 carries an upward current of 1.50 A. To the right, wire 2 carries a downward current of 3.60 A. Wire 3 is to be located such that when it carries a certain current, each wire experiences no net force.

And now we need to find the position of wire 3 and the magnitude and direction of the current in wire 3.

As per the given question, we know that the

=> Current in wire 1, i1 =1.2A upward

=> Current in wire 2, i2=5A downward

And the distance between wire 1 and 2 is calculated is

=> 20cm = 0.2m

Here the current is calculated as

=> F/l = μo•i1•i3/2πx

So,

=> F/l=6×10⁻⁶N/m

=> 6×10⁻⁶ = μo•i1•i3/2πx

=> 6×10⁻⁶ =4π×10⁻⁷×1.2×i3/(2π×0.0632)

When we do Cross multiply,

=> 2.383×10⁻⁶=4π×10⁻⁷×1.2×i3

Step-by-step explanation:

⭐What is the slope of a line?

⭐What is the slope of a line that is parallel to another line?

Therefore, we can just find the slope of the given line and put that as our answer.

Before we do that, we need to rewrite the equation in slope-intercept form. ([tex]y = mx + b[/tex])

x + y = -6

To do so, subtract x from the LHS (left-hand side) and RHS (right-hand side) to isolate "y"

x + y -x = -6 -x

y = -x + 6

The slope is the coefficient of the x-variable.

-1 is the coefficient of the x-variable.

Therefore, -1 is the slope of this line.

Parallel lines have the same slope of the line they are parallel to.

Therefore, -1 is the slope of the line parallel to this line.
