Ans = 62.5% seats occupied

Answer:

A

Step-by-step explanation:

We know that ∠[tex]ABE[/tex] ≅ ∠[tex]DBC[/tex] because they are vertical angles, so that's one pair of congruent angles. However, we can't compare ∠[tex]BAE[/tex] and ∠[tex]DCB[/tex] as they have different measures, so we'll have to find the measure of either ∠[tex]AEB[/tex] or ∠[tex]BDC[/tex]. Let's go with the former. Using the fact that the sum of the measures of the interior angles of a triangle is [tex]180[/tex]°, we know that [tex]m[/tex]∠[tex]AEB=180-(53+42)=180-95=85[/tex]°. Now, we know that ∠[tex]AEB[/tex] ≅ ∠[tex]DCB[/tex] because their measures are equal. That's another pair of congruent angles. Therefore, the angles are similar by [tex]AA[/tex]. Hope this helps!

Answer:

1,600 dollars

Step-by-step explanation:

The easiest way to solve it is to find the dollar for 1 percent.

Since 480 accounts for 30% of the whole thing, we can do 480 divided by 30 to get 16 as 1 percent. This means that 16 times 100 percent would give us the total money spent, giving us 1,600 as our answer.

Answer: y = -2x + 5

Step-by-step explanation:

y = -2x + 5

slope = -2

Slope intercept form of equation of line is given by y = mx + c

where m is the slope of line

c is the y intercept i.e point where given line intersect y axis.

________________________________________________

given equation 4x + 2y = 10

we have to re-write this equation in form y = mx + c

4x + 2y = 10

subtraction 4x from LHS and RHS

4x + 2y - 4x= 10 - 4x

2y = 10- 4x

we have to eliminate 2 from y for that we

divide  LHS and RHS by 2 we

2y /2 = 10/2- 4x/2

y = 5 - 2x

rearranging it in y = mx+c form

y = -2x + 5

thus, m = -2 , c = 5

Answer:

y=-2x+5, slope= -2, y-intercept= 5 (so, first option)

Step-by-step explanation:

y=mx+b. m is the slope, and b is the y-intercept. to get the equation to the slope intercept form, you get y by itself- subtract 4x from both sides and then divide by 2 on both sides.

Answer:

[tex]x=16 \ \ and \ \ y=4[/tex]

Step-by-step explanation:

Suppose the numbers are x and y

One number say x is equal to 4 times another number say y

[tex]x=4y[/tex]  ---------------- (1)

Their difference is 12

[tex]x-y=12[/tex]  ------------(2)

Put x=4y in equation (2)

[tex]4y-y=12[/tex]

[tex]3y=12\\y=4[/tex]

Put y=4 in equation (1)

[tex]x=4(4)\\x=16[/tex]

Answer:

proportion: 1.93/23 = y/x

solve for y: y = x(0.083913)

Step-by-step explanation:

The required relationship of the proportionality is y = 0.08 x.

Given that,
In 23 minutes, Halona travels 1.93 kilometers to a neighbor's home. assuming she moves at a steady pace.
How many kilometers, y, Halona can walk in x minutes, expressed as a proportion. After that, find y using your percentage.

The relationship between two or more sets of values—whether they are directly proportional or inversely proportional to one another—is referred to as proportionality.

Here,
according to the question,
y ∝ x
y = kx
Where k is the constant of the proportionality,
at x = 23, y = 1.93
1.93 = 23 k
k = 1.93/23
k = 0.08
Put k in the proportionality equation,
y = 0.08k

Thus, the required relationship of the proportionality is y = 0.08 x.

Answer:

a) 1 nm = 0. 000 000 001 m

b) 1 nm = 1×10⁻⁹ m

Answer:

let x be cost of a hotdog

let y be cost of hamburger

so,

5x + 4y = 17.75                    eq. 1

4x + 5y = 18.25                    eq. 2

manipulate eq. 1 so solve for x:

5x = 17.75 - 4y

x = 17.75/5 - (4/5)y

x = 3.55 - (4/5)y                  eq. 3

substitute eq. 3 to eq. 2:

4(3.55 - (4/5)y) + 5y = 18.25

14.2 - (16/5)y + 5y = 18.25

14.2 + (9/5)y = 18.25

(9/5)y = 18.25 - 14.2

4.05= (9/5)y

y = 2.25

x = 3.55 - (4/5)(2.25)

x = 1.75

hotdog costs $1.75

hamburger costs $2.25

[tex]Brother = 105 + 3d[/tex]

Step-by-step explanation:

Given

[tex]Drone = d[/tex]

Friend = $35 more expensive than yours.

Brother = 3 * as much as your friend

Required

Write an expression for the cost of your brother's drone

I'll solve by analysing the question one sentence after the other

You:

[tex]Drone = d[/tex]

Your friend:

Friend = $35 more expensive than yours.

This means

[tex]Friend = 35 + You[/tex]

Substitute d for You

[tex]Friend = 35 + d[/tex]

Your brother:

Brother = 3 * as much as your friend

This means:

[tex]Brother = 3 * Friend[/tex]

Substitute 35 + d for Friend

[tex]Brother = 3 * (35 + d)[/tex]

Open bracket

[tex]Brother = 3 * 35 + 3*d[/tex]

[tex]Brother = 105 + 3d[/tex]

Answer:

The values of p and q such that 2·x² - 4·x + 3 = 2·(x - p)² + q, are;

p = 1, q = 1

Step-by-step explanation:

The given equation are;

2·x² - 4·x + 3 = 2·(x - p)² + q

By expanding the right hand side of the equation, we have;

2·x² - 4·x + 3 = 2·(x - p)² + q = 2·x² - 4·p·x + 2·p² + q

2·x² - 4·x + 3  = 2·x² - 4·p·x + 2·p² + q

Comparing the coefficient of x in both equations, gives;

2·x² + (- 4)·x + 3  = 2·x² + (- 4·p)·x + 2·p² + q

-4 = -4·p

∴ p = -4/(-4) = 1

p = 1

Comparing only the constant terms (terms not multiplied by "x" or "x²"), we get;

3 = 2·p² + q

Substituting the value for "p" obtained above (p = 1 ) in the previous equation, we get;

3 = 2 × 1² + q  = 2 + q

∴ q = 3 - 2 = 1

q = 1.

I put a ladder 1.5m away from a tree.

The ladder is inclined at 70 degrees about the horizontal.

We need to find out what is the height of the tree.

It is given by:

Tan Ф = Perpendicular / Base

Draw a figure of the given statement.

<--------1.5m-------->              

Find the AB.

AB = height of the tree.

TanФ = AB / CB

Tan 70° = AB / 1.5m

2.7474 = AB / 1.5m

AB = 2.7474 x 1.5m

AB = 4.12 m

Thus the height of the tree is 4.12 m.
